  • 00:00Good afternoon, everyone, and welcome
  • 00:02to Grand Rounds.
  • 00:04I've already muted. I'm muted.
  • 00:05Thanks. Sam was just trying
  • 00:06to adjust the comfort level
  • 00:08in the room for anyone
  • 00:08that's, a little bit too
  • 00:10cozy at the moment. Thank
  • 00:11you, Sam.
  • 00:12So today is our last
  • 00:14Grand Rounds of this year.
  • 00:15I'd like to start by
  • 00:16wishing you all a very
  • 00:17happy holiday season and happy
  • 00:19new year. We'll be getting
  • 00:20started on January seventh with
  • 00:22doctor Linda Mays with her,
  • 00:24annual address to kick off
  • 00:26Grand Rounds for next year.
  • 00:27But today, we're ending on
  • 00:29a high, and we're delighted
  • 00:31that doctor Kasia Habarska has
  • 00:33decided to give grand rounds
  • 00:34today. All of you know,
  • 00:36doctor Habarska
  • 00:38and her fantastic work trying
  • 00:39to identify,
  • 00:40early diagnostic farm,
  • 00:42markers and novel treatment targets
  • 00:44for autism spectrum disorders.
  • 00:47Doctor Hovashka is the, Emily
  • 00:48Fraser Beatty professor of child
  • 00:50psychiatry, pediatrics, and statistics,
  • 00:53and is the director of
  • 00:54the NIH funded, Center for
  • 00:56Excellence, for autism spectrum disorders
  • 00:58here at the Yale Child
  • 00:59Study Center. And so, please
  • 01:01join me in welcoming Kasia
  • 01:02and thanking her for giving
  • 01:03the last grand rounds of
  • 01:04twenty twenty four.
  • 01:10Thank you so much. You
  • 01:11know, it's always,
  • 01:13it's always fun to give
  • 01:14talks,
  • 01:15but it's always the greatest
  • 01:16pleasure to do it at
  • 01:17home. So, I'm really grateful
  • 01:19for this opportunity, and thank
  • 01:20you for for inviting me.
  • 01:22And thanks for everyone being
  • 01:24here. I know this is
  • 01:25the busiest time of
  • 01:27the year, and I know,
  • 01:29many of us are still
  • 01:30in connects
  • 01:31right now.
  • 01:33But I really appreciate everyone
  • 01:34online and here in the
  • 01:35room for being here.
  • 01:38So,
  • 01:39the reason behind this talk
  • 01:41is behind this topic is
  • 01:42that,
  • 01:44Kelly,
  • 01:45a group of amazing clinicians
  • 01:47in in our lab, in
  • 01:48our clinic, Kelly,
  • 01:51Paula, Mariana Torres, and Chelsea
  • 01:53Morgan.
  • 01:54And I have been, having
  • 01:56discussions
  • 01:56about,
  • 01:57differential diagnosis in babies.
  • 02:00Right?
  • 02:02Spurred by the fact can
  • 02:04you hear me?
  • 02:05Spurred? No. I I think
  • 02:06I'm I think I'm using
  • 02:08it. Can you hear me?
  • 02:08Yes.
  • 02:10Okay.
  • 02:11Spurred by the fact that,
  • 02:12in, in the past twenty
  • 02:14five years, we've been seeing
  • 02:15a lot of toddlers in,
  • 02:17our clinics and through research
  • 02:18programs.
  • 02:20And, we are always struck
  • 02:21by the complexity
  • 02:22of the clinical presentation
  • 02:25and,
  • 02:26and difficulty sometimes in considering,
  • 02:28what the primary diagnosis might
  • 02:30be and, difficulties in making
  • 02:32predictions,
  • 02:34about outcomes,
  • 02:35of these kids. So today,
  • 02:37I would like to invite
  • 02:38you to kind of walk
  • 02:39with me through what we
  • 02:41know, what we don't know,
  • 02:42and think about,
  • 02:44where we would like to
  • 02:45be in ten years, from
  • 02:46now in terms of,
  • 02:48creating new
  • 02:50or better diagnostic,
  • 02:52approaches to early diagnosis. We're
  • 02:54gonna talk about a little
  • 02:55bit about the,
  • 02:58concept of differentiation.
  • 03:00We'll talk about,
  • 03:02you know, what what do
  • 03:03we know about early manifestation
  • 03:05of some of the,
  • 03:06complex neurodevelopmental
  • 03:08conditions we deal with, including
  • 03:10autism and ADHD,
  • 03:13some clinical implications
  • 03:14about from what we know
  • 03:16or we don't know,
  • 03:18and, perhaps about some new
  • 03:20directions or or or glimpses
  • 03:22of new directions,
  • 03:24that might, might give us
  • 03:25a little bit more a
  • 03:26better sense or different sense
  • 03:28of of,
  • 03:29of, differential diagnosis.
  • 03:32So, I want you to
  • 03:33sit back and imagine
  • 03:35that in a galaxy far,
  • 03:36far away,
  • 03:38little brains,
  • 03:40read the diagnostic instruments.
  • 03:42And,
  • 03:44accordingly they develop accordingly to
  • 03:46what they read and, develop
  • 03:48very nicely separated
  • 03:51phenotypes.
  • 03:52They are very clearly,
  • 03:54delineated
  • 03:55and, very clearly,
  • 03:57defined.
  • 04:01In our galaxy, however,
  • 04:03in our Milky Way galaxy,
  • 04:05things are a little different.
  • 04:07At at the least, we
  • 04:08see significant overlaps between,
  • 04:11children who are presenting with
  • 04:14neurodevelopmental
  • 04:15conditions being autism, global delays,
  • 04:18language,
  • 04:18disorders, or or motor stereotypies.
  • 04:22Actually, this may look,
  • 04:25complicated.
  • 04:27There's a delay in the
  • 04:28display.
  • 04:29Is that okay?
  • 04:32There's a bit of a
  • 04:32delay in the display of
  • 04:33the slides.
  • 04:37Okay. So I'll just now
  • 04:38that I know it's there,
  • 04:40I will be mindful about
  • 04:41that. Sorry about this. So
  • 04:42so this is pretty much
  • 04:43what we see in our
  • 04:44clinics. It's much more likely
  • 04:46to see we're much more
  • 04:47likely to see in the
  • 04:48in our clinics
  • 04:49considerable overlap
  • 04:51between, in symptom expression,
  • 04:53in children representing for differential,
  • 04:56diagnosis.
  • 04:58If that was really the
  • 04:59case, this would be actually
  • 05:00very nice.
  • 05:01In reality, what we are
  • 05:02seeing is something like that.
  • 05:04It's something like that. The
  • 05:06children who are referred to
  • 05:07us for differential diagnosis,
  • 05:09one, two, three,
  • 05:11four,
  • 05:12five,
  • 05:13six, seven, eight, nine, ten.
  • 05:16We have a delay.
  • 05:18Can we?
  • 05:22Can we do something about
  • 05:23it?
  • 05:24Do you want to I
  • 05:26think everything we need to
  • 05:26do is stop share and
  • 05:27reshare.
  • 05:28Uh-huh.
  • 07:30Clinics is something like that.
  • 07:32We see some children who
  • 07:33are presenting with a more
  • 07:34clear clinical pictures,
  • 07:37that we can see here
  • 07:38clustering the same color on
  • 07:39the periphery.
  • 07:40But in reality, we also
  • 07:42see a lot of kids
  • 07:43who are actually presenting in
  • 07:44multiplicity of symptoms
  • 07:46coming from a variety of
  • 07:47different, syndromes. And our
  • 07:50job here is to make
  • 07:52a,
  • 07:53clinically,
  • 07:54informed, relevant, and helpful to
  • 07:57the family,
  • 07:58differentiation.
  • 08:04Sam.
  • 08:06Hi, Sam.
  • 08:14Ten seconds.
  • 08:16I got slides on the
  • 08:17computer here if you want.
  • 08:18Do whatever. Yeah.
  • 08:21Yeah.
  • 08:22Do whatever. So how many
  • 08:24people are, here working with,
  • 08:27faced with the issue of
  • 08:28differential diagnosis on a daily
  • 08:30basis?
  • 08:33Lots of clinicians.
  • 08:34So it's relevant.
  • 08:36You know, I typically do
  • 08:37research. I I don't see
  • 08:39patients these days a lot,
  • 08:41but it's also tremendously important
  • 08:42from us from the, research
  • 08:44standpoint because after all, after
  • 08:46it's all said and done,
  • 08:48we do,
  • 08:49most cases,
  • 08:50come back to the question,
  • 08:52what is the group? What
  • 08:53is the differential? Right? How
  • 08:55can we come how can
  • 08:56we differentiate our complex phenotypes
  • 08:59in order to, at the
  • 09:00end, end up with phenotypes
  • 09:01which are separated enough so
  • 09:03we can actually see something
  • 09:05important or or new, in
  • 09:07terms of our,
  • 09:09outcome variables.
  • 09:23Oh,
  • 09:24that's awesome.
  • 09:26You think? Oh, yeah. She
  • 09:28did that.
  • 09:29She did that thing as
  • 09:30well.
  • 09:41I think everything is in
  • 09:42holiday mode already. So
  • 09:45Just
  • 09:47be chill.
  • 09:48Be chill.
  • 09:49Go down. Down. Down.
  • 09:51Down. Right here.
  • 09:53Okay.
  • 09:55Do I get another five
  • 09:56minutes?
  • 09:57Yeah. Of course.
  • 09:59I'll be very, very fast.
  • 10:01I'll be super fast. So,
  • 10:02anyway, so what do we
  • 10:03have to do?
  • 10:04Advance this? Yeah.
  • 10:07That
  • 10:08yep. Thank you. Okay. So
  • 10:10what do we have to
  • 10:10do? We have to make
  • 10:11this differentiation.
  • 10:12So what is the differentiation
  • 10:14in our case? It's really
  • 10:15an act of identifying differences
  • 10:17between things between entities and
  • 10:19trying to come up with
  • 10:21the the sort of the
  • 10:22sharpest,
  • 10:23boundaries between them in order
  • 10:25to tell them apart.
  • 10:27It's when this principle is
  • 10:29applied to psychopathology, things can
  • 10:31get a little complicated.
  • 10:33The premise here is that,
  • 10:36psychiatric and developmental conditions,
  • 10:38are really manifestations
  • 10:40different kind of,
  • 10:42conditions are manifestations of distinct,
  • 10:45pathophysiology.
  • 10:46And, our role is to
  • 10:49find the boundaries
  • 10:50between these entities and separate
  • 10:53the groups. So separate the
  • 10:54phenotypes into ideologically,
  • 10:56homogeneous groups, groups that will
  • 10:58also have certain clinical significance
  • 11:01in terms of implications for
  • 11:02prognostication
  • 11:03and for treatment.
  • 11:06What's interesting about this approach
  • 11:08is that the boundaries are
  • 11:09actually refined as our knowledge,
  • 11:12expands. And you can see
  • 11:13it very well here in
  • 11:14the d s in the
  • 11:15progression of the diagnostic statistics
  • 11:17manual,
  • 11:19from very early ages. You
  • 11:20see that little thick little
  • 11:22thin thin little thing,
  • 11:24over time. So becoming more
  • 11:26and more thicker,
  • 11:28as more knowledge is accumulated
  • 11:30and as things, as as
  • 11:31the concept diagnostic concepts begin
  • 11:34to evolve.
  • 11:36A very good example of
  • 11:37this evolution is a concept
  • 11:39of autism.
  • 11:41Autism has been around for
  • 11:42a while, not quite a
  • 11:43century yet as a diagnostic
  • 11:45entity. And in nineteen forty
  • 11:47three, Kenner described the first,
  • 11:50set of of clinical cases,
  • 11:52and he called the syndrome,
  • 11:54inborn autistic disturbance of affective
  • 11:57contact.
  • 11:58It's a very mouthful,
  • 11:59kind of thing.
  • 12:02This term has been further
  • 12:04refined,
  • 12:05when, DSM three DSM two
  • 12:07came on board in the
  • 12:09nineteen seventies.
  • 12:10In its label,
  • 12:12autism was linked very closely
  • 12:14to schizophrenia.
  • 12:15It was called childhood schizophrenic
  • 12:17reaction.
  • 12:19DSM
  • 12:20three in nineteen eighty,
  • 12:22began to recognize the idea
  • 12:23that autism is a very
  • 12:25complex disorder. It needs to
  • 12:26be a very heterogeneous disorder
  • 12:29and perhaps will be better
  • 12:30served if we fractionate it
  • 12:33into different subtypes. In this
  • 12:35case, they called it, infantile
  • 12:37autism and then sub threshold
  • 12:39pervasive developmental disorder.
  • 12:43Nineteen ninety four, comes along,
  • 12:45and Fred Bockmar,
  • 12:47leads the DSM,
  • 12:49for,
  • 12:50task for for autism,
  • 12:52and the fractionation
  • 12:55further,
  • 12:56develops and, Asperger
  • 12:58disorder is added to the,
  • 13:00to the to the fold.
  • 13:03But two thousand thirteen.
  • 13:06Another roundtable discussion
  • 13:09results in the ideas that,
  • 13:10you know, we we would
  • 13:11like to fractionate,
  • 13:13this heterogeneous syndrome,
  • 13:15but we really, don't have
  • 13:16a good good way of
  • 13:17doing it. So why don't
  • 13:18we just put this all
  • 13:19together into a single category
  • 13:21called autism spectrum,
  • 13:23disorder?
  • 13:26This is I can tell
  • 13:27you, already, this is twenty
  • 13:29three, eleven years later. I
  • 13:31can tell you that this
  • 13:31is not the end of
  • 13:32the story.
  • 13:34We are beginning to talk
  • 13:35again about fractionation of the
  • 13:37syndrome
  • 13:37into, for instance, something that's
  • 13:39called profound
  • 13:41autism.
  • 13:42So more to come. But
  • 13:44but the idea is that
  • 13:45our diagnostic
  • 13:46boundaries
  • 13:48evolve over time,
  • 13:49and we need to be
  • 13:50mindful of that evolution that
  • 13:52we are part of the
  • 13:53process.
  • 13:54Nothing is written in stone.
  • 13:56So
  • 13:58when we think about young
  • 13:59kids,
  • 14:02there are a number of
  • 14:03disorders that either can
  • 14:06manifest themselves or
  • 14:09may have prodromal
  • 14:10characteristics
  • 14:11already online,
  • 14:13during the first three years
  • 14:14of life. Tons of stuff.
  • 14:16Autism,
  • 14:18attention deficit disorder, hyper hyperactivity,
  • 14:22intellectual disabilities, speech disorders, various
  • 14:25speech disorders, learning disorders,
  • 14:27stereotypic movement disorder, anxiety,
  • 14:30conduct,
  • 14:31and and probably a few
  • 14:32others you can name. So
  • 14:34there's a tremendously
  • 14:36dense space
  • 14:38very early on
  • 14:40in which is these these
  • 14:41symptoms can be expressed, and
  • 14:43they would be expressing very
  • 14:44young and immature neurodevelopmental
  • 14:46systems.
  • 14:49I'm going to focus today
  • 14:50on on two things, on
  • 14:51autism and ADHD, not because
  • 14:53I know anything about ADHD,
  • 14:55but I had to learn
  • 14:56because Kelly would not let
  • 14:58me,
  • 14:59go without that.
  • 15:00So, I'm going to talk
  • 15:02about these two disorders because,
  • 15:04they're actually,
  • 15:07quite co current, and there's
  • 15:08some interesting similarities and differences
  • 15:10between them. And people sometimes
  • 15:12wonder whether this is maybe
  • 15:13the same thing,
  • 15:15or maybe maybe the symptoms
  • 15:17that we see of ADHD
  • 15:19in autism are completely different
  • 15:21story than when we see
  • 15:22them in, ADHD.
  • 15:24So both types the both
  • 15:26disorders have very early onset,
  • 15:28sometimes before the age of
  • 15:29three or five.
  • 15:31Very high
  • 15:32prevalence, in the population. Tremendous,
  • 15:34heritability,
  • 15:36which suggests that genetic factors
  • 15:38play a very, very important
  • 15:40role.
  • 15:41Unaffected family members,
  • 15:44have,
  • 15:45features that are related to
  • 15:47the to the to the
  • 15:48disorder. So they in autism,
  • 15:50we have broader autism phenotype,
  • 15:52and there's something,
  • 15:53similar in, in ADHD.
  • 15:57They are both developmental conditions.
  • 15:58Symptoms change, evolve over time,
  • 16:01as children grow and,
  • 16:04and become,
  • 16:06become more,
  • 16:07capable.
  • 16:09There's higher prevalence in boys.
  • 16:12There's a spectrum severity. Some
  • 16:14kids are very impaired. Some
  • 16:15some are mildly affected.
  • 16:17And each of these conditions
  • 16:19have many co occurring,
  • 16:22conditions as well.
  • 16:26Interesting,
  • 16:28stat there's a number of
  • 16:29studies right now, that suggest
  • 16:31that there's actually quite significant
  • 16:32genetic overlap between autism and
  • 16:34ADHD with about thirty, forty
  • 16:36percent of genes shared between
  • 16:38the two,
  • 16:39disorders.
  • 16:40There are studies emerging on
  • 16:42brain, connectivity,
  • 16:43brain structure also showing some
  • 16:45similarities
  • 16:46as well as differences.
  • 16:48And about thirty percent of
  • 16:49kids with autism will have
  • 16:51ADHD,
  • 16:52and many more will have
  • 16:53some symptoms without meeting formal
  • 16:56diagnosis
  • 16:57of ADHD.
  • 16:59Also, about thirty to forty
  • 17:00percent of kids with ADHD
  • 17:02will have some elevation of
  • 17:05symptoms of autism,
  • 17:07be it in a social
  • 17:08or repetitive domains.
  • 17:11Am I doing okay, Kelly?
  • 17:15So, what do we know
  • 17:16about emergence of these two,
  • 17:19syndromes in early childhood? Right?
  • 17:21Because if you want to
  • 17:22differentiate them, we know what
  • 17:24they are, what they look
  • 17:25like. What is the prototype
  • 17:27of autistic toddlers? What is
  • 17:29the prototype of a toddler
  • 17:30with ADHD?
  • 17:32And only if we have
  • 17:33that, we can begin to
  • 17:34make,
  • 17:35differentiations.
  • 17:37So,
  • 17:39until about twenty years ago,
  • 17:40autism was not diagnosed until
  • 17:42the age,
  • 17:43five years,
  • 17:44of age.
  • 17:45And when I came to
  • 17:46Yale here
  • 17:47twenty five years ago or
  • 17:49so, these were the discussions
  • 17:50Fred and I were having
  • 17:51that, you know, this is
  • 17:52the state of the art.
  • 17:53Anything that's happening could be
  • 17:55earlier. It's really hard to
  • 17:57differentiate from anything, and we
  • 17:59cannot really
  • 18:00we don't have right instruments
  • 18:02to diagnose kids with with
  • 18:04autism.
  • 18:05That changed. You know? Here,
  • 18:06we open in the year
  • 18:08two thousand. We opened one
  • 18:09of the first clinics in
  • 18:10the country that focus on
  • 18:12autism under the age of
  • 18:13three,
  • 18:15which was, which was something
  • 18:16that was extremely innovative at
  • 18:18that point. I'm still happy
  • 18:20to say that we are
  • 18:21running the same clinic.
  • 18:23And,
  • 18:24through our work, through work
  • 18:26of our colleagues around the
  • 18:28country, tremendous effort went in
  • 18:30to understanding the syndrome
  • 18:32in the first,
  • 18:34in in in in toddler's
  • 18:36second or third year of
  • 18:37life.
  • 18:38We found out that, yes,
  • 18:40we can,
  • 18:41identify
  • 18:42symptoms in nonverbal and developmental
  • 18:44light kids that are specific
  • 18:46to autism.
  • 18:47There's a whole list of
  • 18:48them.
  • 18:49And also,
  • 18:51our colleagues,
  • 18:52including Cathy Lord have developed,
  • 18:55valid and reliable instruments for
  • 18:57quantifying
  • 18:58these symptoms in very, very
  • 19:00young kids. So
  • 19:02so we've made tremendous
  • 19:04progress in understanding
  • 19:05what a prototype of autism
  • 19:07might look like in very
  • 19:09early
  • 19:10ages.
  • 19:11And, of course, we had
  • 19:12to ask the question, is
  • 19:13there anything else happening,
  • 19:15before that during this prodromal
  • 19:17stage between birth and the
  • 19:19second birthday?
  • 19:20First birthday,
  • 19:22complex
  • 19:24conditions do not arise overnight.
  • 19:26There's got to be something
  • 19:28else happening
  • 19:29in the brain, in the
  • 19:31behavior that is forecasting
  • 19:33later emergence of the syndrome.
  • 19:35And, indeed,
  • 19:36lots of work
  • 19:38went into studying younger siblings
  • 19:40of children with autism who
  • 19:42have,
  • 19:42elevated risk for developing,
  • 19:44the disorder.
  • 19:46And,
  • 19:48and work here,
  • 19:49in our lab, for instance,
  • 19:52documented,
  • 19:53that,
  • 19:54way before symptoms of autism
  • 19:56come online, we can see
  • 19:57attentional,
  • 19:59vulnerabilities in six month old
  • 20:01babies more recently. We are
  • 20:02looking actually at the,
  • 20:04brain,
  • 20:05structure and connectivity in neonates
  • 20:07in relation to later outcomes
  • 20:09in these siblings.
  • 20:11So,
  • 20:12lots of work, happening in
  • 20:14that space,
  • 20:15and, and it's definitely more
  • 20:17to come.
  • 20:18In that context,
  • 20:20if I can make a
  • 20:21quick plug, we are just
  • 20:22starting a new,
  • 20:24study that's focused on brain
  • 20:26imaging
  • 20:27in newborns.
  • 20:28So if you're pregnant, if
  • 20:29you're thinking of getting pregnant,
  • 20:31if you know someone who's
  • 20:32pregnant, or if you know
  • 20:33someone who's pregnant who has
  • 20:34a family member of a
  • 20:36child with autism, do let
  • 20:37us know.
  • 20:39We'll be delighted delighted to
  • 20:41say hello to them.
  • 20:43So what's happening,
  • 20:45in ADHD? Again, we're looking
  • 20:47for a prototype. What do
  • 20:48we know about ADHD in
  • 20:49young kids? Same stories with
  • 20:51autism.
  • 20:52Not typically diagnosed until the
  • 20:54age of five. People started
  • 20:56asking questions what's happening before
  • 20:59for good reasons,
  • 21:00including the fact that the
  • 21:02parents were telling everyone.
  • 21:04My child always was like
  • 21:06that. Why are we talking
  • 21:07about
  • 21:08the diagnosis now?
  • 21:10So,
  • 21:11there has been some research
  • 21:13in that space, but certainly
  • 21:14not as much as we
  • 21:16did as as it happened
  • 21:17in autism.
  • 21:19There has been some research
  • 21:20on fine tuning diagnostic criteria
  • 21:23so they can be extended
  • 21:24to kids who are younger
  • 21:26by excluding some of the
  • 21:28verbal items. So that was
  • 21:29great.
  • 21:30And research in this space
  • 21:32is actually quite spare. It's
  • 21:34it's largely focused on temperamental
  • 21:36indices
  • 21:37where researchers ask parents to
  • 21:39rate their children along multiple
  • 21:41dimensions
  • 21:42and, children, the
  • 21:44tend to have,
  • 21:46surprisingly, or maybe not high
  • 21:48activity level, elevated
  • 21:50propensity to respond with negative
  • 21:52affect to, challenges, environmental
  • 21:55challenges,
  • 21:56and difficulty sustaining
  • 21:58attention.
  • 21:59And they also may may
  • 22:00show some elevated,
  • 22:03social and repetitive behaviors,
  • 22:05that are typically associated with
  • 22:07autism.
  • 22:09But,
  • 22:10we know much less about
  • 22:12them, as we, know about
  • 22:14toddlers with autism. And when
  • 22:15we think about potential prodrome,
  • 22:17we are not even calling
  • 22:18it necessarily a prodrome yet
  • 22:20in ADHD.
  • 22:21There is not much work.
  • 22:22There's some work on on,
  • 22:25babies who later were diagnosed
  • 22:27with autism, and and they
  • 22:29also this research also suggests
  • 22:30that there are some temperamental
  • 22:32markers
  • 22:33temperamental features,
  • 22:35that are seen in kids
  • 22:36who develop autism, but these
  • 22:38are not diagnostic markers. None
  • 22:40of these are specific to
  • 22:41autism.
  • 22:42ADHD, they are seen in
  • 22:44other kids.
  • 22:45So,
  • 22:48very, very limited.
  • 22:50I wish, you know, if
  • 22:51this was my wish, if
  • 22:52I could do anything, if
  • 22:53I had the same money
  • 22:54as, Bezos,
  • 22:55I would invest it really
  • 22:57into trying to understand the
  • 22:59early program of, a lot
  • 23:01of the new developmental conditions,
  • 23:04because this is the time
  • 23:05and space,
  • 23:06for doing that,
  • 23:08but we are not quite
  • 23:09there yet. So what are
  • 23:10the clinical implications?
  • 23:11So I I'm eternally grateful
  • 23:13to Kelly, Mariana, and Chelsea
  • 23:15for helping with this table,
  • 23:17which basically summarizes,
  • 23:19clinical,
  • 23:22wisdom
  • 23:23of, you know, what happens
  • 23:24when you get into the
  • 23:25room with with a toddler.
  • 23:26The toddler's climbing the walls,
  • 23:28not really responding to name,
  • 23:30not really looking necessarily
  • 23:32in in the eyes,
  • 23:33and not playing so well
  • 23:35that you could say, okay.
  • 23:37They they are finding that
  • 23:38domain.
  • 23:39So how do you how
  • 23:40do you separate? How do
  • 23:42you make a differentiation whether
  • 23:43on a no. These difficulties
  • 23:45are due to
  • 23:46social disability
  • 23:48or attentional
  • 23:49challenges.
  • 23:51I could spend an hour
  • 23:52talking about this table, but
  • 23:54I can only I can
  • 23:55plug some of these things.
  • 23:57So for instance,
  • 23:59young kids, preschoolers with autism,
  • 24:02ADHD have
  • 24:03often elevated scores
  • 24:05on screeners for autism.
  • 24:08It could be an AMCHAT,
  • 24:10SRS,
  • 24:11maybe even an ADOS based
  • 24:13on the work we do
  • 24:14in our in our clinic.
  • 24:16So, in the context of
  • 24:18face to face interaction, they
  • 24:20might not make eye contact.
  • 24:21They may have
  • 24:23a problem with they might
  • 24:24be a little grabby. They
  • 24:25might be getting in your
  • 24:26space. They might be not
  • 24:27looking at you and so
  • 24:29forth. And and what we
  • 24:30found the most important is
  • 24:32to consider context
  • 24:33and manipulate the,
  • 24:36environmental
  • 24:37variables
  • 24:38to see whether we can
  • 24:39enhance the child's engagement
  • 24:42by, limiting number of distractions
  • 24:44by scaffolding in in in
  • 24:46some ways.
  • 24:48And if we can do
  • 24:49that, we can say safely,
  • 24:51okay. This child is not
  • 24:52really making a lot of
  • 24:53eye contact, but,
  • 24:55because he's so distracted
  • 24:56by everything. He's he needs
  • 24:58to grab everything at the
  • 24:59same time and,
  • 25:00climb the walls.
  • 25:02So, his social engagement is
  • 25:03a little,
  • 25:04law on a lower side.
  • 25:08Same goes with with language.
  • 25:09We see language delay across
  • 25:11developmental conditions.
  • 25:13Again, what's important for us
  • 25:15is ability to communicate without
  • 25:17words in autism is profoundly
  • 25:19affected
  • 25:20and,
  • 25:21and,
  • 25:24scaffolding it in a context
  • 25:26of social interaction
  • 25:27hardly ever makes it better,
  • 25:29where it whereas it makes
  • 25:30it much better for kids
  • 25:31with ADHD or other conditions.
  • 25:35Kids, with ADHD
  • 25:36often also show,
  • 25:39repetitive behaviors,
  • 25:41motor therapy, sensory interests, which
  • 25:44are often seen in autism,
  • 25:46and and that often makes
  • 25:48people think, oh, wow. This
  • 25:49kid must have ate, autism.
  • 25:52But, first of all,
  • 25:55therapy or or more or,
  • 25:57repetitive behaviors are not specific
  • 25:59to autism.
  • 26:00They're also present in multiple
  • 26:02conditions. So in and of
  • 26:03themselves, they are not good
  • 26:05diagnostic
  • 26:06indicator.
  • 26:09So, all of this is
  • 26:10not,
  • 26:11is not really,
  • 26:13a a matter of academic
  • 26:14discussion because,
  • 26:16children who have, dual diagnosis,
  • 26:19autism and ADHD,
  • 26:21typically do much worse than
  • 26:22children who only have autism.
  • 26:24And that's true of school
  • 26:26age children and also true
  • 26:28of children,
  • 26:29who are much younger, who
  • 26:30are preschoolers.
  • 26:32And for that reason, we
  • 26:33need to try to include
  • 26:35screenings for screening for ADHD,
  • 26:38for, even very young kids,
  • 26:41in order to identify potential
  • 26:43risk factors, which are going
  • 26:44to actually
  • 26:45affect their outcomes in a
  • 26:47very, very significant way.
  • 26:51So,
  • 26:54given the complexity of our
  • 26:56tasks in clinics on a
  • 26:58on a daily basis,
  • 26:59we need to consider several
  • 27:01things.
  • 27:02Whatever we do, however we
  • 27:04differ try to differentiate
  • 27:05what we see is going
  • 27:07to depend tremendously
  • 27:08on the quality of information
  • 27:10that's available to us.
  • 27:12And yet,
  • 27:14across the world,
  • 27:15we are facing tremendous pressure
  • 27:18to simplify diagnostic processes, to
  • 27:21do less, to do more
  • 27:22with less,
  • 27:24to,
  • 27:25use screening instruments instead of,
  • 27:29instead of more,
  • 27:30direct,
  • 27:31assessment methods, and use less
  • 27:34experienced clinicians to in to
  • 27:36interpret this data, make decisions
  • 27:38about diagnosis,
  • 27:40and, prescribe treatment.
  • 27:44Given the complexity
  • 27:45of of the of the
  • 27:47of the landscape and psychopathology
  • 27:49they are face faced with,
  • 27:51I would like to argue
  • 27:52that we need to stick
  • 27:54to the old school,
  • 27:56for now
  • 27:57until we develop better measures
  • 27:59or biological markers.
  • 28:01Stick to the old school,
  • 28:03assessments where we actually employ,
  • 28:05clinicians who are highly,
  • 28:07highly trained
  • 28:09and are capable of assessing
  • 28:12functioning across multiple areas of
  • 28:14functioning. This this is the
  • 28:15only way we can actually
  • 28:16prescribe
  • 28:17treatment. Treatment will depend
  • 28:19on the child's individual profile
  • 28:22of strength and weaknesses, and
  • 28:23I feel like I'm channeling
  • 28:25Sarah Sparrow here.
  • 28:26Right, Lori?
  • 28:29Amen.
  • 28:32Also a pervasive presence of
  • 28:34of co co occurring conditions
  • 28:35truly,
  • 28:37calls for, paying attention to
  • 28:39other dimensions that that we
  • 28:40don't,
  • 28:41typically, and and screen also
  • 28:43for emotional problems, attentional, and
  • 28:45regulatory functions.
  • 28:49Keeping
  • 28:50while we do all of
  • 28:51this, while we do all
  • 28:52this important work,
  • 28:54in in our clinics, we
  • 28:56also,
  • 28:57give ourselves a bit of
  • 28:58a break
  • 28:59and, and remember that this
  • 29:01uncertainty that we expect experience,
  • 29:05is real.
  • 29:06It's real for several reasons.
  • 29:07One is that the diagnostic
  • 29:08boundaries we are operating
  • 29:10with
  • 29:11are,
  • 29:12are changing.
  • 29:13Right? They're evolving. It's an
  • 29:15evolving science. They are still
  • 29:16under development.
  • 29:18And we need to remember
  • 29:19that.
  • 29:20These are
  • 29:21not platonic
  • 29:23forms, Plato's forms,
  • 29:24that that we are referring
  • 29:26to.
  • 29:28Also,
  • 29:31sometimes the source of uncertainty
  • 29:33is
  • 29:34the changes
  • 29:35in the presentation
  • 29:36over time in very young
  • 29:38kids.
  • 29:41And that's something to be
  • 29:42expected
  • 29:43because we are trying to
  • 29:45nail down or pinpoint some
  • 29:47kind of
  • 29:48constellation of features in the
  • 29:50system, your developmental system that's
  • 29:52rapidly changing,
  • 29:54right, in terms of brain
  • 29:56connectivity,
  • 29:57brain structure, brain
  • 29:59you know, how behavior, environment
  • 30:01shapes shapes these important,
  • 30:03determinants
  • 30:04of outcomes.
  • 30:06And, also, we are changing
  • 30:08the kids.
  • 30:09You know, when a child
  • 30:10comes to to to the
  • 30:11clinic
  • 30:12and we prescribe treatment and
  • 30:14we see them again and
  • 30:15they're fabulous,
  • 30:17we probably changed the kid.
  • 30:19It's not that we've made
  • 30:20a mistake the first time
  • 30:21around.
  • 30:23You know, there's a very
  • 30:24interesting example from the studies
  • 30:26of baby siblings of children
  • 30:28with autism. We have a
  • 30:29consortium that's sort of,
  • 30:31in in the US or
  • 30:32actually international consortium.
  • 30:34And we look at the
  • 30:35babies across time,
  • 30:38several thousands of them. Right?
  • 30:40It's stunning because
  • 30:42once the child
  • 30:44is detected once we detect
  • 30:45that the child has difficulties,
  • 30:47twelve months, fourteen months, sixteen
  • 30:48months, we prescribe treatment.
  • 30:50And then when we look
  • 30:51at this group,
  • 30:53thousands of babies,
  • 30:54they are so doing so
  • 30:56much better than general population
  • 30:58of kids with autism. So
  • 30:59much better.
  • 31:01We're changing reality. There's
  • 31:03there's also possible that there
  • 31:04are some protective factors that
  • 31:05are kicking in. And another
  • 31:07example is, girls with autism.
  • 31:09When we see them when
  • 31:10they're very young, we see
  • 31:11quite a few girls who
  • 31:13have, you know, prototypical
  • 31:14presentation
  • 31:15in a toddler
  • 31:16of autism. But
  • 31:18there is a there's a
  • 31:19significant group of girls who
  • 31:21actually do better over time
  • 31:22than boys.
  • 31:24As if, you know, the
  • 31:25protective some protective factors were
  • 31:27kicking in or compensatory factors
  • 31:29were kicking kicking in, and
  • 31:31their trajectories
  • 31:32are going to diverge from
  • 31:33those that we see in
  • 31:34voice.
  • 31:36When in doubt, always,
  • 31:37fall back on provisional diagnosis.
  • 31:40We use
  • 31:41what do we like? We
  • 31:42like,
  • 31:43un specifying your developmental condition,
  • 31:46treat symptoms, reevaluate,
  • 31:47and,
  • 31:48most importantly, support family
  • 31:51throughout the process.
  • 31:53Your uncertainty should not be.
  • 31:55There are uncertainty.
  • 31:57Okay. So, how much time
  • 31:59do I have?
  • 32:01Twenty five minutes.
  • 32:02Oh my god.
  • 32:05Okay. So I really zoomed
  • 32:07through it. Alright. So,
  • 32:10alright. So this is great.
  • 32:11Fantastic. So I can slow
  • 32:13it down.
  • 32:15So
  • 32:16what are the alternatives?
  • 32:18Right?
  • 32:20What are the alternatives?
  • 32:21I told you about, methods
  • 32:23that
  • 32:24are capitalized on differences.
  • 32:26Right?
  • 32:28Defining boundaries, capitalizing on differences,
  • 32:31comparing groups, and hoping for
  • 32:33the largest separation of of
  • 32:35distributions,
  • 32:37in terms of diagnosis.
  • 32:39So another approach is to
  • 32:42focus on similarities.
  • 32:44Right? We already talk about
  • 32:45the fact that,
  • 32:47there are similarities
  • 32:49in in,
  • 32:51same symptoms might be present
  • 32:52across multiple conditions.
  • 32:55Right?
  • 32:56And so,
  • 32:57we can focus on that
  • 32:58and try to understand what
  • 32:59is that about.
  • 33:01Right?
  • 33:02I mean, there there's there's
  • 33:03several assumptions,
  • 33:05associated with this approach.
  • 33:08First, that symptoms are distributed
  • 33:10on a continuum,
  • 33:11and there are some
  • 33:14some symptoms like social engagement,
  • 33:16social motivation,
  • 33:19selective attention,
  • 33:21variability, nonverbality
  • 33:23is distributed on a continuum
  • 33:24with with some very low
  • 33:26scores and very high scores,
  • 33:28something in the middle.
  • 33:29And different disorders might be
  • 33:31falling onto different kind of,
  • 33:34place in this in this
  • 33:35in this continuum.
  • 33:37And there's also an assumption
  • 33:38in this approach that the
  • 33:39symptoms,
  • 33:41seen across different conditions are
  • 33:43driven by the same psychopathology.
  • 33:45Now these two points may
  • 33:47seem very simple,
  • 33:48and straightforward, but they are
  • 33:50not. They're extremely complicated, and
  • 33:52there's a lot of work
  • 33:53going on to try to
  • 33:54figure out
  • 33:55which symptom dimensions actually fall
  • 33:57under these these these categories.
  • 33:59So if we were to,
  • 34:00for instance, think about
  • 34:03can you see that? Yep.
  • 34:04I can see that. So
  • 34:05if you if if you
  • 34:06can print for instance, think
  • 34:08about two dimensions. Right? You
  • 34:09know, social engagement and repetitive
  • 34:11behaviors, and this is a
  • 34:13zero. You can imagine that
  • 34:14if we take several disorders,
  • 34:17if you take autism, ADHD,
  • 34:19intellectual disability,
  • 34:20individuals
  • 34:21from different,
  • 34:23different individuals might fall into
  • 34:25different,
  • 34:26parts of this distribution.
  • 34:27Right? And this is the
  • 34:29simplest,
  • 34:30two dimensional,
  • 34:31representation
  • 34:32of these of these,
  • 34:34possible,
  • 34:35dimensions.
  • 34:36But, in reality, we're probably
  • 34:38looking at many, many, many
  • 34:40more.
  • 34:41Now this trust diagnostic and
  • 34:43dimensional approach is mostly right
  • 34:45now used in research.
  • 34:47It has not I don't
  • 34:48think unless unless I miss
  • 34:50something, has not trickled down
  • 34:52yet to clinical,
  • 34:54practice or clinical applications.
  • 34:57Just to give you some
  • 34:58like, an example of of,
  • 34:59you know, how this work
  • 35:01can be done, how it's
  • 35:02done, how it might inform
  • 35:03clinical practice
  • 35:05is, I'll I'll I'll walk
  • 35:07you through,
  • 35:08some of the,
  • 35:10recommendations
  • 35:11or frameworks, research frameworks that
  • 35:13were advanced by the National
  • 35:15Institutes of Mental Health.
  • 35:19They identify
  • 35:20several important
  • 35:22domains
  • 35:23of, psychopathology.
  • 35:25And within each domain, there's
  • 35:26specific dimensions.
  • 35:29So, you know, negative positive
  • 35:31valence, cognitive systems, social processing,
  • 35:35and so forth. And within
  • 35:36each of them, are there
  • 35:38specific
  • 35:40groups or dimensions or of
  • 35:41symptoms that can be considered
  • 35:43or important in psychopathology?
  • 35:46One of these,
  • 35:47one of these domains is
  • 35:49a sensory
  • 35:50motor domain, and sensory motor
  • 35:51domain
  • 35:52includes, many different things that
  • 35:54has to do with with
  • 35:55motor planning, habits,
  • 35:59and so forth. But it
  • 36:00also includes something that we
  • 36:01call a repetitive movements or
  • 36:04motors stereotypies. And I'm going
  • 36:05to talk about this for
  • 36:06a moment
  • 36:07just to give you, this
  • 36:09kind of work as an
  • 36:10example of what what we
  • 36:11can do and maybe where
  • 36:12we're gonna go with our
  • 36:13field.
  • 36:14So,
  • 36:15complex motor stereotypies,
  • 36:18involve,
  • 36:19repetitive,
  • 36:20habitual
  • 36:21movements of of fingers, hands,
  • 36:25other body parts.
  • 36:27They're,
  • 36:29they need to be distinguished
  • 36:30from so called simple motor
  • 36:32therapies that could be nail
  • 36:33biting or
  • 36:35or,
  • 36:37similar things that we see
  • 36:38in in very young or
  • 36:39thumb sucking or related,
  • 36:43related behaviors.
  • 36:45Motor steatibis are present,
  • 36:47in autism, and they're also
  • 36:49present in other, conditions.
  • 36:51They are distributed in a
  • 36:53spectrum of severity.
  • 36:55Some are so severe that
  • 36:57they cause,
  • 36:58injury,
  • 36:59self injury, and some of
  • 37:01them are completely benign,
  • 37:03present, but completely,
  • 37:05benign.
  • 37:06There's an ongoing
  • 37:07discussion in the field whether,
  • 37:09these,
  • 37:11repetitive movements are purposeless
  • 37:14or whether we call them
  • 37:15purposeless only because we don't
  • 37:16understand their function.
  • 37:18And,
  • 37:20their function
  • 37:21in theory could involve many
  • 37:23many very helpful things
  • 37:25like regulation of arousal,
  • 37:28and,
  • 37:29reactivity.
  • 37:30And we don't know much
  • 37:31about the underlying
  • 37:33etiology, but we know it's
  • 37:34it's a biological phenomenon.
  • 37:36There's some genetic markers for
  • 37:38for for stereotypies.
  • 37:41So, give you a couple
  • 37:42of examples. This is this
  • 37:44is a beautiful little girl
  • 37:45who,
  • 37:46came to us through our
  • 37:48complex motor therapies
  • 37:50complex
  • 37:53complex neurodevelopmental
  • 37:54condition program. Sorry about that.
  • 37:57And she came to us
  • 37:59when she was about twelve
  • 38:00months old. This is her
  • 38:01six at six months.
  • 38:04And she started doing these
  • 38:05little things
  • 38:08and,
  • 38:10moving her feet
  • 38:12when they're excited.
  • 38:15She's clearly not perturbed.
  • 38:18If anything, she's happy.
  • 38:20But it worried the parents.
  • 38:22This was her a little
  • 38:23bit
  • 38:25later when she could sit
  • 38:26on her own
  • 38:29when she came to see
  • 38:30us, and this was her
  • 38:34Do you wanna go sit
  • 38:35at the table too? So
  • 38:36motor stereotypies here involve
  • 38:38hands and, happy feet, happy
  • 38:40hands,
  • 38:41movements, also adding some, composition
  • 38:44of of, face grimacing,
  • 38:47of of posturing.
  • 38:49This child does not have,
  • 38:52any neurological
  • 38:53condition other than than motor
  • 38:55motor stereotypy.
  • 38:56No no epilepsy.
  • 39:00So,
  • 39:01we wanted to understand,
  • 39:03this phenomenon a little better,
  • 39:04and we've been working with
  • 39:05with Tom and his group.
  • 39:08Tom has truly pioneered the
  • 39:09research on motor stereotypical here
  • 39:11at the child study center.
  • 39:12We started talking
  • 39:14what might what might this
  • 39:15look like in toddlers.
  • 39:17Not too many people actually
  • 39:18look at this phenomenon in
  • 39:19toddlers.
  • 39:20So we wanted to ask
  • 39:21the question,
  • 39:22what are toddlers like,
  • 39:24and what is the underlying
  • 39:25potentially biology?
  • 39:27So we took we leveraged
  • 39:29findings from over seven hundred
  • 39:30toddlers who came through our
  • 39:32clinics,
  • 39:33and we, were able to
  • 39:34evaluate their motorist their tippies
  • 39:36based on direct
  • 39:37assessment.
  • 39:39And, the first thing that
  • 39:40we we found was quite
  • 39:42interesting was that the prevalence
  • 39:43is is actually,
  • 39:45distribution is kind of interesting.
  • 39:47Sixty percent,
  • 39:49of kids with autism had
  • 39:51mother's third tip is so
  • 39:52not everyone.
  • 39:53Right? Thirty percent of kids
  • 39:55without autism, with other conditions,
  • 39:57had motor stereotypies, and about
  • 39:59ten percent
  • 40:00of kids without anything
  • 40:02also showed some stereotype behaviors.
  • 40:05So that was interesting.
  • 40:08What we also did, we
  • 40:09we controlling for the diagnostic
  • 40:12grouping. We also look for
  • 40:13association
  • 40:15between presence
  • 40:16of motor stereotypies
  • 40:18and,
  • 40:19developmental
  • 40:20outcomes both concurrently and prospectively.
  • 40:23And it was also very
  • 40:25interesting because the presence of
  • 40:26motor stereotyping was associated with
  • 40:29a low lower cognitive skills,
  • 40:31a low lower language skills,
  • 40:33less social skills.
  • 40:35And it was true,
  • 40:38both concurrently and also prospectively,
  • 40:41which suggested something something very
  • 40:44interesting,
  • 40:45to us that that
  • 40:47seeing a child with moderate
  • 40:48stereotyping may signal
  • 40:50that we actually should be
  • 40:52paying attention even though the
  • 40:53child may just have simple
  • 40:55motor stereotyping. We need to
  • 40:56actually pay attention to
  • 40:58what is else is happening
  • 41:00in their development.
  • 41:02Now a lot of,
  • 41:03effort went into discussion. What
  • 41:05is the relationship between mother
  • 41:06stereotypies and and, let's say,
  • 41:08cognition
  • 41:09or, language or social functioning?
  • 41:13And some people propose that
  • 41:14mother stereotypies actually cause them.
  • 41:16There's a causal relationship. They
  • 41:18prevent the child from engaging
  • 41:20into something that's more adaptive
  • 41:22and so forth. We see
  • 41:23absolutely no evidence for that.
  • 41:26If anything,
  • 41:27we think that what is
  • 41:29really happening is that the
  • 41:30neural circuitry
  • 41:32that's responsible
  • 41:33or involved in producing,
  • 41:35motor cell TPC is also
  • 41:37involved in controlling
  • 41:40cognition,
  • 41:40attention, executive
  • 41:42function, and language.
  • 41:44So multiple functions
  • 41:46are subserved
  • 41:47by the same
  • 41:49by the same complex and,
  • 41:52subcortical to cortical circuitry.
  • 41:55And
  • 41:56perhaps any kind of alteration
  • 41:58within this when the within
  • 41:59this network can produce a
  • 42:01broad spectrum
  • 42:03of developmental,
  • 42:05outcomes, including,
  • 42:06motors.
  • 42:08So,
  • 42:09so this is really the
  • 42:10first paper of this kind
  • 42:12in in toddlers, but we
  • 42:13we we try to recommend
  • 42:15that,
  • 42:16a presence of,
  • 42:18moderate stereotypies should really, trigger
  • 42:20monitoring, developmental monitoring.
  • 42:22And, if there are,
  • 42:25if there are any persistent
  • 42:27patterns of delays, also intervention
  • 42:29focus not on motor stereotypies,
  • 42:31but on the delays that
  • 42:32we see in other domains.
  • 42:34Intervening on stereotypies, it's a
  • 42:36whole different thing because
  • 42:38a motor stereotypies typically are
  • 42:40not unless they are lead
  • 42:42to self injury,
  • 42:43they're actually not,
  • 42:45impinging upon the child's,
  • 42:48happiness or well-being or or,
  • 42:51they're not distressing.
  • 42:53So,
  • 42:54unless they are distressing, we
  • 42:55need to be very, very
  • 42:56careful and very judicial in,
  • 42:59considering,
  • 43:00treatment.
  • 43:01And in in that consideration,
  • 43:03we need to take,
  • 43:04really, really seriously,
  • 43:07we need to understand very
  • 43:08seriously,
  • 43:09the function
  • 43:10and the, and and what
  • 43:12what really is the family
  • 43:14take on it or the
  • 43:15child's take on what's happening
  • 43:16with their own body.
  • 43:18So it's not an automatic
  • 43:20target for treatment.
  • 43:22So,
  • 43:23with things like stereotypies, which
  • 43:25we think might be a
  • 43:26dimension that cuts across multiple,
  • 43:29disorders,
  • 43:30maybe driven by the same,
  • 43:32mechanisms. We we don't know
  • 43:33yet. We are collecting some
  • 43:35genetic data,
  • 43:36on on our cohort. We
  • 43:38might know a little bit
  • 43:39more,
  • 43:40later.
  • 43:42Tom's earlier work has shown
  • 43:43that there are some overlaps
  • 43:45between,
  • 43:46risk genes for autism and
  • 43:47complex motor
  • 43:49therapies,
  • 43:50in children without autism.
  • 43:52So lots to come. This
  • 43:54is really definitely a space
  • 43:56that that requires a lot
  • 43:57of attention.
  • 43:58But before we even go
  • 44:00to underlying biology, we have
  • 44:01to measure them using the
  • 44:02same instruments.
  • 44:04Everyone measures them differently.
  • 44:06It's really, really hard to
  • 44:08put together,
  • 44:09some sensible conclusions from studies
  • 44:12where where the phenomenon is
  • 44:13measured,
  • 44:14by parent report, by a
  • 44:16checklist of of two items,
  • 44:18by observe
  • 44:19observation
  • 44:20and so forth.
  • 44:25What's also very important is
  • 44:26for us to, we owe
  • 44:28it to our families and
  • 44:29to the kids to understand
  • 44:31their functional significance
  • 44:32because that's a highly neglected
  • 44:34area, right now, and and
  • 44:36we are trying to get
  • 44:37into that space as well.
  • 44:39And and be very, very
  • 44:40careful in terms of interventions.
  • 44:45So
  • 44:49with that, I would like
  • 44:50to thank you. I would
  • 44:51like to thank thank you
  • 44:52for your attention and
  • 44:54acknowledge,
  • 44:55all the families to come
  • 44:57through our,
  • 44:58studies and our funding agencies.
  • 45:00Amazing, amazing team,
  • 45:03in my lab and the
  • 45:04clinic.
  • 45:06And,
  • 45:06thank you very much for
  • 45:08your attention.
  • 45:16Well, thank you very much,
  • 45:17Kasia, especially for giving the
  • 45:19talk. Everybody's on an incredibly
  • 45:21warm room. This is
  • 45:24I'm I'm surprised that no
  • 45:25one's falling asleep.
  • 45:27Well, it's I've seen some
  • 45:28ice closed.
  • 45:32Questions for doctor Habashkin.
  • 45:37Thank you. Thank you, Kasia.
  • 45:39I have a comparative
  • 45:40question. So as you know,
  • 45:41I'm a primatologist
  • 45:43and in
  • 45:44monkey
  • 45:45literature, at least with monkeys
  • 45:47that exhibit self injurious behavior,
  • 45:49there have been studies showing
  • 45:51that they direct their biting
  • 45:53to acupressure points and that
  • 45:54lowers heart rate. So that
  • 45:56supports the arousal reduction.
  • 45:58I'm not aware of any
  • 46:00research into stereotypies, but monkeys
  • 46:02do exhibit stereotypical behaviors as
  • 46:04well. And I'm just wondering,
  • 46:05is there any work that's
  • 46:07starting to examine this arousal
  • 46:09reduction hypothesis
  • 46:10in children?
  • 46:12This is absolutely fascinating.
  • 46:14I I did not know
  • 46:15about that. Well, we,
  • 46:18there's very, very few studies
  • 46:20which try to evaluate Matthew
  • 46:22Goodwin comes to mind from
  • 46:23Northwestern who tried to monitor
  • 46:26arousal throughout the day
  • 46:28in people with autism who
  • 46:29are,
  • 46:31moving around and doing their
  • 46:32going be, about their lives
  • 46:34and try to,
  • 46:36identify some patterns in in
  • 46:38arousal changes, whether there's some
  • 46:39kind of rise be right
  • 46:40before,
  • 46:41what's happened after the the
  • 46:43start of the. It's really,
  • 46:45really hard. Yeah. There was
  • 46:46there was one study from
  • 46:47our colleagues from Netherlands in
  • 46:49the
  • 46:50nineties, I would say. Really
  • 46:52good study. Maybe ten patients.
  • 46:55Matthew did maybe similar number
  • 46:58of so not not really.
  • 47:00There's not much. We're we
  • 47:01are recording,
  • 47:04skin conductance
  • 47:05throughout their visits when they
  • 47:06come to our clinic.
  • 47:09It's a better analyze
  • 47:10data if anyone is interested.
  • 47:15Yes. A lot of work
  • 47:16needs to happen.
  • 47:28K. K. K.
  • 47:29Thank you so much. I
  • 47:30am wondering if you put
  • 47:32on an ethics hat
  • 47:34and
  • 47:35talk about,
  • 47:36to whom it's impairing
  • 47:39these stereotype behaviors and what
  • 47:41movement we've made
  • 47:43societally
  • 47:45to,
  • 47:46be more accepting
  • 47:48of these behaviors that
  • 47:50are not impairing,
  • 47:52to the child.
  • 47:54They might be socially
  • 47:56stigmatizing, but they're not impairing.
  • 47:57And so there's a real
  • 47:58ethical dilemma about targets
  • 48:01of treatment.
  • 48:02And maybe you could tell
  • 48:03us what's happening in the
  • 48:04autism world about
  • 48:07taking an ethics lens
  • 48:09to targets of behavior.
  • 48:11This is an excellent question.
  • 48:13It's about, is it ethical
  • 48:14to to intervene if the
  • 48:16symptoms are not
  • 48:17interfering with the child's well-being?
  • 48:20And this is exactly the
  • 48:21argument that has been raised
  • 48:22by the autism advocates
  • 48:24who,
  • 48:26who
  • 48:27bring up the issue. You
  • 48:28know, these behaviors help me.
  • 48:30When I walk into,
  • 48:32this, you know, very busy
  • 48:33environment and I engage in
  • 48:36something that's comforting,
  • 48:38it helps me stay in
  • 48:39that environment.
  • 48:40So they they point clearly
  • 48:43to functional significance of these
  • 48:45behaviors.
  • 48:46I think in science, we
  • 48:47are behind that because we've
  • 48:49taken the the the perspective
  • 48:51of looking from the outside
  • 48:52in
  • 48:53and saying, you know, this
  • 48:55looks weird.
  • 48:56And and can we can
  • 48:57we normalize it? Right?
  • 49:00And and I think, thankfully,
  • 49:01the field is moving from
  • 49:03from from from this approach.
  • 49:05And it applies to children
  • 49:06with autism, but it also
  • 49:07applies to children with with,
  • 49:09motorist
  • 49:10who have no no other,
  • 49:13cognitive or or language or
  • 49:14other difficulties
  • 49:16and who will display these
  • 49:17behaviors. And we are seeing
  • 49:18them. We are seeing them
  • 49:20in in our through our
  • 49:22program.
  • 49:23Some of them, especially when
  • 49:24we see them as older
  • 49:25kids, Kelly, you can say
  • 49:27something more about that.
  • 49:29They they they developed their
  • 49:30own way of saying about
  • 49:31it. So, you know, I
  • 49:32I was born like that.
  • 49:33Like, we ask, you
  • 49:35know, how does it feel?
  • 49:36You know? What what do
  • 49:37you think about it? You
  • 49:38know? How do you,
  • 49:40like, negotiate
  • 49:41your life in the in
  • 49:42the classroom?
  • 49:43Room? And she's they would
  • 49:45say just, you know, I
  • 49:46was born like that.
  • 49:48And,
  • 49:49and kind of try to
  • 49:50send send their ground,
  • 49:52you know, governing.
  • 49:55So so,
  • 49:57I I think
  • 49:58as a society, we have
  • 50:00a lot to do
  • 50:02to be able to accept
  • 50:03people for who they are
  • 50:05if they are different because
  • 50:06we really don't
  • 50:08our our our tolerance for
  • 50:10otherness
  • 50:12is extremely limited,
  • 50:14and we see it across
  • 50:17multiple phenomena, not just psychopathology.
  • 50:20And and we need to
  • 50:21create space where
  • 50:23people can be who they
  • 50:24are.
  • 50:34Thank you so much.
  • 50:37Now transitioning to putting on
  • 50:39a clinical hat,
  • 50:41I am wondering
  • 50:42I have a lot of
  • 50:43parents that I've been working
  • 50:44with over this year that
  • 50:46will say,
  • 50:47we have a picture of
  • 50:48ADHD
  • 50:49and
  • 50:50some
  • 50:51autistic like traits,
  • 50:53and parents will say, well,
  • 50:55is it autism or is
  • 50:56it not? What does it
  • 50:57mean? What are these extra
  • 50:59stereotypical behaviors or what what
  • 51:01do the extra things mean?
  • 51:03I'm wondering what you might
  • 51:05be
  • 51:06able to say or what
  • 51:08would you say to the
  • 51:09parents in that situation, and
  • 51:11what could be helpful for
  • 51:12us as clinicians to be
  • 51:14able to educate them about?
  • 51:17You know, it's it's a
  • 51:18very important question. We want
  • 51:20certainty.
  • 51:22We really don't like uncertainty.
  • 51:24We don't we don't like
  • 51:25to be sort of, one
  • 51:27foot here, one foot there.
  • 51:31From you know, everyone is
  • 51:33different. Right? So so with
  • 51:34different families, you you take
  • 51:36a different approach.
  • 51:37What's important for us is
  • 51:39that when we see families
  • 51:40for diagnostic evaluation and and
  • 51:42we know there are complex
  • 51:43questions ahead,
  • 51:46Every moment we spend with
  • 51:47them, it's a it's a
  • 51:48psychoeducational
  • 51:49moment.
  • 51:50Right? We discuss, you know,
  • 51:52what are your concerns? What
  • 51:53do you think it it
  • 51:53might be? Right? And, you
  • 51:55know, tell me about your
  • 51:56family. Tell me about,
  • 51:59who else in the family
  • 52:00may have x, y, and
  • 52:01z. Right? And and sort
  • 52:03of try to open them
  • 52:04up to the
  • 52:06to the various possibilities
  • 52:07and the fact that, development
  • 52:09is a beautiful thing. It's
  • 52:11a nonlinear.
  • 52:12And and we often use
  • 52:13that argument with with families,
  • 52:15which is a great thing
  • 52:17because that means possibilities are
  • 52:18endless.
  • 52:28Tasha,
  • 52:34thank you so much for
  • 52:35a great presentation.
  • 52:37Since you spoke about,
  • 52:40ADHD
  • 52:41versus autism,
  • 52:42can you comment a little
  • 52:44bit about, any updates on
  • 52:46the theory of mind research
  • 52:48and how ADHD and autism
  • 52:50might be different with regard
  • 52:52to this theory of mind,
  • 52:54field?
  • 52:57That's an excellent question.
  • 53:00I am I am more
  • 53:02focused on low kids
  • 53:04than
  • 53:06older kids, and I have
  • 53:08less of an understanding
  • 53:10of the theory of mind
  • 53:11differentiation.
  • 53:14In the nineties,
  • 53:17and the odds, there was
  • 53:18a strong emphasis on the
  • 53:20theory of mind impairment in
  • 53:22in autism.
  • 53:24It's the the picture is
  • 53:26probably not as straightforward
  • 53:28as we thought it was,
  • 53:30back then.
  • 53:31So, I'm not up to
  • 53:33speed on this literature in
  • 53:34terms of more sophisticated
  • 53:38levels of differentiation.
  • 53:42Maybe someone else is in
  • 53:43the audience.
  • 53:49Well, I think the message
  • 53:50of resisting the urge to
  • 53:52other people is a wonderful
  • 53:53message
  • 53:54to end the twenty twenty
  • 53:55four grand round series on.
  • 53:57So if there are no
  • 53:58further questions for doctor Vashka,
  • 54:00I'd like to,
  • 54:01thank you very much for
  • 54:02a wonderful presentation.
