Join the Jackson School for Trump in the World 2.0, a series of talks and discussions on the international impact of the second Trump presidency.

This week: Daniel Bessner; Anne H.H. and Kenneth B. Pyle Associate Professor in American Foreign Policy at the Henry M. Jackson School of International Studies.


Monday, June 2, 5:00 – 7:00 pm | (Jackson School)

Mediha Sorma, Ph.D

This talk discusses the unconventional forms of care that emerge out of Kurdish resistance in Turkey, where mothering becomes a powerful response against necropolitical state violence. By centering the stories of two Kurdish mothers who had to care for their dead children and mother beyond life under the violent state of emergency regime declared in 2015; the talk examines how Kurdish mothers 鈥渞escue the dead鈥 (Antoon, 2021) from the necropolitical state and create their necropolitical power through a radical embrace of death and decoupling of mothering from the corporeal link between the mother and the child.


Monday, June 2, 3:30 – 5:00 pm | (The Ellison Center for Russian, East European and Central Asian Studies)

Prof. Masaaki Higashijima

Why do some protests in autocracies attract popular participation while others do not? Masaaki Higashijima’s, University of Tokyo, paper argues that when opposition elites and the masses have divergent motivations for protesting, anti-regime mobilization struggles to gain momentum. Moreover, this weak elite-mass linkage is further exacerbated when autocrats selectively repress protests led by opposition elites while making concessions to those organized by ordinary citizens.

 


Tuesday, June 3, 5:00 – 6:30 pm | (Communications)

Mary Gates Hall

A conversation with local public media leaders about current challenges–including federal funding cuts–and pathways forward for sustaining public service journalism.

Rob Dunlop, President and CEO, Cascade PBS
David Fischer, President and General Manager, KNKX
Tina Pamintuan, incoming President and CEO, KUOW
Matthew Powers, Professor and Co-Director, Center for Journalism, Media and Democracy


Wednesday, June 4, 3:30 – 4:30 pm | (Psychology)

Prof. Hadas Okon-Singer

Cognitive biases 鈥 such as attentional biases toward aversive cues, distorted expectations of negative events, and biased interpretations of ambiguity 鈥 are central features of many forms of psychopathology. Gaining a deeper understanding of the neurocognitive mechanisms underlying these biases is crucial for advancing theoretical models and clinical interventions.

In this talk, Prof. Hadas Okon-Singer will present a series of studies exploring emotional biases in both healthy individuals and participants diagnosed with social anxiety, major depressive disorder, and generalized anxiety disorder.


Wednesday, June 4, 12:30 – 1:30 pm | (Center for Statistics & Social Sciences)

Prof. Tyler McCormick

Many statistical analyses, in both observational data and randomized control trials, ask: how does the outcome of interest vary with combinations of observable covariates? How do various drug combinations affect health outcomes, or how does technology adoption depend on incentives and demographics? Tyler McCormick’s, Professor, Statistics & Sociology, 天美影视传媒, goal is to partition this factorial space into “pools” of covariate combinations where the outcome differs across the pools (but not within a pool).

UW Information School ties for 1st; other UW programs place highly in US News & World Report Best Graduate Schools ranking /news/2025/04/07/uw-information-school-ties-for-1st-other-uw-programs-place-highly-in-us-news-world-report-best-graduate-schools-ranking/ Tue, 08 Apr 2025 04:06:29 +0000 /news/?p=87887 Drone shot
The UW鈥檚 graduate and professional degree programs were widely recognized as among the best in the nation, according to U.S. News & World Report鈥檚 2026 Best Graduate Schools rankings. Photo: 天美影视传媒

UPDATE April 8,2025: An earlier version of this story included outdated rankings that were erroneously posted by U.S. News and have since been removed from the U.S. News ranking site. This story has been updated to reflect most recent rankings.

Many of the 天美影视传媒鈥檚 graduate and professional degree programs were widely recognized as among the best in the nation, according to .

The UW Information School tied for No. 1 alongside the University of Illinois Urbana-Champaign for library and information studies. And, more than 80 UW schools and departments placed prominently in the 2026 rankings.

While the UW celebrates the success and impact of the programs recognized by U.S. News 鈥 and notes that many applicants use these rankings to help them select schools and discover potential areas of study 鈥 the University also recognizes shortcomings inherent in the ranking systems.

The UW School of Law and the UW School of Medicine withdrew from the U.S. News rankings in 2022 and 2023, respectively, citing concerns that some of the methodology in the rankings for those specific disciplines incentivize actions and policies that run counter to the schools鈥 public service missions.

UW leaders continue to work with U.S. News and other ranking organizations to improve their methodologies, to the extent that the organizations are open to it. Schools, colleges and departments continually reevaluate the benefits and potential shortfalls of participating in specific rankings.

鈥淎s these rankings demonstrate, the UW鈥檚 outstanding graduate and professional degree programs are leading the way in training highly skilled people to fill critical workforce needs and advance discovery and innovation in a wide range of fields,鈥 said UW President Ana Mari Cauce. 鈥淚t has never been more important to recognize how much graduate and professional education benefit our nation and people everywhere, and the UW is proud to see these exceptional programs be celebrated.鈥

Excluding the School of Law and the School of Medicine, 32 UW programs placed in the top 10, and more than 80 are in the top 35.

In new rankings released this year, the UW placed in the top 10 nationwide in library and information studies, public affairs, nursing, speech and language pathology, education, public health, computer science, psychology and civil engineering, according to U.S. News.

The UW鈥檚 Evans School of Public Policy & Governance has maintained its top-10 ranking for more than a decade and placed seventh in the nation. The Evans School鈥檚 environmental policy program was ranked second and nonprofit management and social policy each were ranked at No. 8.

This year鈥檚 rankings highlighted UW鈥檚 leadership in nursing and public health: The UW School of Nursing held the No. 1 overall ranking for a public school offering a doctor of nursing practice program, and nursing schools at UW Bothell and UW Tacoma are among the top 10 public institutions that offer a master鈥檚 degree. The School of Public Health has maintained its top-10 ranking for more than a decade, coming in this year tied for No. 10. The school also had three programs in the top 10: biostatistics, environmental health sciences and epidemiology. And overall, the U.S. News rankings noted UW鈥檚 strength in health sciences: The School of Social Work was ranked No. 7 and the School of Pharmacy tied for 12th 鈥 or third among public institutions on the West Coast 鈥 on last year鈥檚 list, while dentistry programs are not ranked.

The UW鈥檚 programs in speech and language pathology tied for No. 5, topping schools on the West Coast.听 Three programs from the College of Education placed in the top 10. And the Paul G. Allen School of Computer Science & Engineering this year tied for seventh place overall, and four programs ranked in the top 10, including artificial intelligence, programming language, systems and theory.

In some cases, such as the College of Arts & Science and the Foster School of Business, U.S. News ranks several professional disciplines housed within academic units. The rankings below are based on preliminary data and may be updated. relies on both expert opinions and statistical indicators.

COVID-19 lockdowns prematurely aged teenage brains, UW study shows /news/2024/09/09/covid-19-lockdowns-prematurely-aged-teenage-brains-uw-study-shows/ Mon, 09 Sep 2024 19:03:32 +0000 /news/?p=86044 Young girl doing schoolwork on a laptop while sitting at a table
New research from the 天美影视传媒 found that lockdowns during the COVID-19 pandemic resulted in unusually accelerated brain maturation in adolescents. Photo: Pixabay

During the COVID-19 pandemic, governments around the world implemented restrictive measures 鈥 such as stay-at-home orders and school closures 鈥 to mitigate the spread of the respiratory illness. It鈥檚 been well-documented that this disruption of daily routines and social activities on the mental health of adolescents.

Adolescence, the period of transition between childhood and adulthood, is marked by dramatic changes in emotional, behavioral and social development. It鈥檚 also a time when a sense of self-identity, self-confidence and self-control are developed. The pandemic reduced social interaction for teenagers and led to documented reports of anxiety, depression and stress, especially for girls.

New research from the 天美影视传媒, published Sept. 9 in the , found the pandemic also resulted in unusually accelerated brain maturation in adolescents. This maturation was more pronounced in girls. When measured in terms of the number of years of accelerated brain development, the mean acceleration was 4.2 years in females and 1.4 years in males.

, ,, , , , , , , , and published related stories.

鈥淲e think of the COVID-19 pandemic as a health crisis,鈥 said , senior author and co-director of the UW (I-LABS), 鈥渂ut we know that it produced other profound changes in our lives, especially for teenagers.鈥

Brain maturation is measured by the thickness of the cerebral cortex, the outer layer of tissue in the brain. The cerebral cortex naturally thins with age, even in teens. Chronic stress and adversity are known to accelerate cortical thinning, which is associated with an increased risk for the development of neuropsychiatric and behavioral disorders. Many of these disorders, such as anxiety and depression, often emerge during adolescence 鈥 with females at a higher risk.

The UW research began in 2018 as a longitudinal study of 160 teens between 9 and 17 years, with the original objective of evaluating changes in brain structure during typical adolescence. The cohort was slated to return in 2020, but the pandemic delayed the repeat tests until 2021. By then, the original intent to study typical teen development was no longer viable.

鈥淥nce the pandemic was underway, we started to think about which brain measures would allow us to estimate what the pandemic lockdown had done to the brain,鈥 said , lead author and research scientist at I-LABS. 鈥淲hat did it mean for our teens to be at home rather than in their social groups 鈥 not at school, not playing sports, not hanging out?鈥

Using the original 2018 data, researchers created a model of expected cortical thinning during the teen years. They then re-examined the brains of the adolescents, over 80% of whom returned for the second set of measurements. The teens鈥 brains showed a general effect of accelerated thinning across adolescence, but this was much more pronounced in females. The cortical thinning effects in females were seen all over the brain, in all lobes and both hemispheres. In males, the effects were only seen in the visual cortex.

The greater impact on female brains as opposed to male brains could be due to differences in the importance of social interaction for girls versus boys, Kuhl said. She added that female teenagers often rely more heavily on the relationships with other girls, prioritizing the ability to gather, talk to each other and share feelings. Boys tend to gather for physical activity.

“Teenagers really are walking a tightrope, trying to get their lives together,鈥 Kuhl said. 鈥淭hey鈥檙e under tremendous pressure. Then a global pandemic strikes and their normal channels of stress release are gone. Those release outlets aren鈥檛 there anymore, but the social criticisms and pressures remain because of social media. What the pandemic really seems to have done is to isolate girls. All teenagers got isolated, but girls suffered more. It affected their brains much more dramatically.鈥

The cerebral cortex is unlikely to get thicker again, Kuhl said, but the potential for recovery might take the form of slower thinning over time, after the return of normal social interactions and outlets. Further research will be needed to see if this is the case.

鈥淚t is possible that there might be some recovery,鈥 Kuhl said. 鈥淥n the other hand, it鈥檚 also possible to imagine that brain maturation will remain accelerated in these teens.鈥

In older populations, measures of cognitive brain function, such as processing speed and the ability to complete typical tasks, correlate with how much the cerebral cortex has thinned. That kind of data is not yet available for teenagers, Kuhl said, but it could be where future research is headed.

鈥淭he pandemic provided a test case for the fragility of teenagers鈥 brains,鈥 Kuhl said. 鈥淥ur research introduces a new set of questions about what it means to speed up the aging process in the brain. All the best research raises profound new questions, and I think that鈥檚 what we鈥檝e done here.鈥

Infants hear significantly more speech than music at home, UW study finds /news/2024/05/30/infants-hear-significantly-more-speech-than-music-at-home-uw-study-finds/ Thu, 30 May 2024 18:42:20 +0000 /news/?p=85604 A woman playing guitar for a toddler. The toddler is laying down and reaching forward to touch the guitar.
For a recent study, researchers analyzed a dataset of daylong audio recordings collected in English-learning infants鈥 home environments at ages 6, 10, 14, 18 and 24 months. Photo: Pixabay

Speech and music are the dominant elements of an infant鈥檚 auditory environment. While past research has shown that speech plays a critical role in children鈥檚 language development, less is known about the music that infants hear.

A new 天美影视传媒 study, published May 21 in , is the first to compare the amount of music and speech that children hear in infancy. Results showed that infants hear more spoken language than music, with the gap widening as the babies get older.

鈥淲e wanted to get a snapshot of what鈥檚 happening in infants鈥 home environments,鈥 said corresponding author , a UW research assistant professor of speech and hearing sciences. 鈥淨uite a few studies have looked at how many words babies hear at home, and they鈥檝e shown that it鈥檚 the amount of infant-directed speech that鈥檚 important in language development. We realized we don鈥檛 know anything about what type of music babies are hearing and how it compares to speech.鈥

Researchers analyzed a dataset of daylong audio recordings collected in English-learning infants鈥 home environments at ages 6, 10, 14, 18 and 24 months. At every age, infants were exposed to more music from an electronic device than an in-person source. This pattern was reversed for speech. While the percentage of speech intended for infants significantly increased with time, it stayed the same for music.

鈥淲e鈥檙e shocked at how little music is in these recordings,鈥 said Zhao, who is also the director of the Lab for Early Auditory Perception (LEAP), housed in the Institute for Learning & Brain Sciences (I-LABS). 鈥淭he majority of music is not intended for babies. We can imagine these are songs streaming in the background or on the radio in the car. A lot of it is just ambient.鈥

This differs from the highly engaging, multi-sensory movement-oriented music intervention that Zhao and her team had . During these sessions, music played while infants were given instruments and researchers taught caregivers how to synchronize their babies鈥 movement with music. A control group of babies then came to the lab just to play.

鈥淲e did that twice,鈥 Zhao said. 鈥淏oth times, we saw the same result: that music intervention was enhancing infant鈥檚 neural responses to speech sounds. That got us thinking about what would happen in the real world. This study is the first step into that bigger question.鈥

Past studies have largely relied on qualitative and quantitative parental reports to examine musical input in infants鈥 environments, but parents tend to overestimate the amount they talk or sing to their children.

This study closes the gap by analyzing daylong auditory recordings made with Language Environment Analysis (LENA) recording devices. The recordings, originally created for a separate study, documented infants鈥 natural sound environment for up to 16 hours per day for two days at each recording age.

Researchers then crowdsourced the process of annotating the LENA data through the citizen science platform. Volunteers were asked to determine if there was speech or music in the clip. When speech or music was identified, listeners were then asked whether it came from an in-person or electronic source. Finally, they judged whether the speech or music was intended for a baby.

Since this research featured a limited sample, researchers are now interested in expanding their dataset to determine if the result can be generalized to different cultures and populations. A follow-up study will examine the same type of LENA recordings from infants in Latinx families. Since audio recordings lack context, researchers are also interested in when music moments are happening in infants鈥 lives.

鈥淲e鈥檙e curious to see whether music input is correlated with any developmental milestones later on for these babies,鈥 Zhao said. 鈥淲e know speech input is highly correlated with later language skills. In our data, we see that speech and music input are not correlated 鈥 so it鈥檚 not like a family who tends to talk more will also have more music. We鈥檙e trying to see if music contributes more independently to certain aspects of development.鈥

Everyday social interactions predict language development in infants /news/2024/04/08/everyday-social-interactions-predict-language-development-in-infants/ Mon, 08 Apr 2024 15:06:32 +0000 /news/?p=84988 A woman sits with a baby facing her on her lap. The woman is talking to the baby using hand gestures. The baby is watching her.
天美影视传媒 researchers found that increased neural activity in response to the social interaction at 5 months predicted enhanced language development at five later ages Photo: Shutterstock

A parent interacting with a baby is a heart-warming and universal scene. The parent speaks in a high-pitched voice 鈥 known as 鈥減arentese鈥 鈥 as they respond positively to the baby鈥檚 babbling and gestures, commonly with eye contact and smiles.

These connections don鈥檛 just make for a touching sight. New research from the 天美影视传媒鈥檚 Institute for Learning & Brain Sciences (I-LABS) shows they鈥檙e important for infant language growth, too.

In a study , researchers used a safe and noninvasive brain-imaging technique called magnetoencephalography, or MEG, to monitor infant brain activity during social and nonsocial interactions with the same adult. They found that when the adult talked and played socially with a 5-month-old baby, the baby鈥檚 brain activity particularly increased in regions responsible for attention 鈥 and the level of this type of activity predicted enhanced language development at later ages. This 鈥榮ocial鈥 scenario was compared with a 鈥榥onsocial鈥 scenario in which the adult turned away from the baby to talk to another person. This interaction showed lower activity levels in the same brain areas.

Watch from I-LABS that explains how infants’ brain responses to social interaction predict future language growth.

鈥淭his is the first study to directly compare infant brain responses to adult-infant social interaction versus nonsocial interaction, and then follow up with the children until they reached the age of 2.5 to see how the early brain activation relates to the child鈥檚 future language abilities,鈥 said lead author , research scientist at I-LABS.

The MEG brain-imaging technology allowed the baby to move and interact naturally with the adult, which enabled researchers to track the firing of neurons from multiple areas in the baby鈥檚 brain as the adult talked to, played with and smiled at the baby. They then monitored the infant鈥檚 brain activity a second time as the adult turned away and paid attention to someone else.

These actions naturally occur every day between adults and babies, and the study showed they have different measurable effects on a baby鈥檚 brain. Researchers found that increased neural activity in response to the social interaction at 5 months predicted enhanced language development at five later ages: 18, 21, 24, 27 and 30 months. The researchers tracked infants鈥 language development using a well-documented and validated survey that asks parents about words and sentences their infants say at home.

鈥淭he connection between early brain reactions and later language is consistent with scientists鈥 fascination with the early age period and opens up many new questions that we, and others, will be exploring,鈥 said co-author , I-LABS co-director and a UW professor of psychology.

Researchers chose 5-month-old babies for the study because that age is just before the 鈥渟ensitive period鈥 for speech-language learning, which begins at about 6 months. Once this period begins, it鈥檚 especially important for infants to observe adults because attention enhances learning.

Using parentese with infants represents an intuitive desire to connect, said , senior author and co-director of I-LABS.

鈥淭here鈥檚 an implicit understanding that language is about connection,鈥 Kuhl said. 鈥淚t鈥檚 about a communicative pathway between you and the other. This starts in infancy with the desire to make that communicative connection.鈥

The study鈥檚 results are particularly important for parents and early educators to understand, Kuhl said.

鈥淲e knew from previous work that social interaction is essential at 9-months of age for foreign-language learning, but the current study shows that social interaction plays a role much earlier,鈥 Kuhl said. 鈥淭he study shows that parents鈥 natural use of parentese, coupled with smiles, touch and their warm back-and-forth responses to the baby鈥檚 actions, have a real-world, measurable impact on the baby鈥檚 brain. We theorize that this parent behavior, which we call 鈥榯he social ensemble,鈥 captures and holds infants鈥 attention and motivates them to learn at a critical time in development.鈥

When the COVID-19 pandemic closed schools nationwide, students of all ages 鈥 from high-schoolers in Advanced Placement classes to preschoolers getting the hang of the ABCs 鈥 shifted to remote learning on a screen.

And while learning to read in an online setting may seem a tall order, a new study by the 天美影视传媒鈥檚 Institute for Learning & Brain Sciences finds that children can develop key reading skills in a virtual classroom with other students. Researchers say their 鈥淩eading Camp鈥 program demonstrates not only the effectiveness of the approach, but also the potential to reach larger numbers of students remotely, by necessity or by choice.

鈥淐hildren are ready to learn to read at the age of 5. But the pandemic robbed children of the opportunity for in-person reading instruction. What we鈥檝e shown here is that an online Reading Camp designed to promote learning socially works phenomenally well. An online camp can be used all over the world by children anywhere, and that is truly exciting,鈥 said faculty author , co-director of I-LABS and a UW professor of speech and hearing sciences.

The , published online March 31 in Frontiers in Human Neuroscience, details a two-week reading program, which teachers provided remotely to 83 5-year-olds beginning in fall 2020.

A screenshot from Reading Camp shows one of the ways the program engaged preschoolers: Teachers wore funny hats, children “voted” for the correct letter and sound with plastic eggs, and each lesson had a theme 鈥 in this case, farm animals. Photo: Institute for Learning & Brain Sciences

Learning to read involves a series of steps, from recognizing distinguished sounds in a language (phonological awareness), to identifying the names of individual letters and how they sound (letter-sound knowledge), to decoding words and their meanings.

The study finds that the participants demonstrated learning of specific reading skills, such as phonological awareness and letter-sound knowledge, when compared to a control group of children who did not receive the instruction.

I-LABS researchers, including study co-author (now at Stanford University), in 2019 offered a two-week reading summer camp to teach early literacy skills to pre-kindergarteners and measure brain activity before and after instruction. With the onset of the pandemic in spring 2020, researchers decided to adapt the in-person Reading Camp into an online version over Zoom.

Ahead of the remote camp, researchers mailed parents a kit of materials, which included headphones, worksheets and books, as well as Play-Doh, toys and other fun items for use in the lessons. Children used colored plastic eggs from the kit, for example, to 鈥渧ote鈥 for the right answer in their virtual classroom, rather than raising a hand.

The Reading Camp grouped children into six-person classrooms, each with two instructors trained in the specific skills lessons. Sessions lasted three hours a day, with several breaks, short lessons broken up by activities, and ending with a story time. The classrooms were often broken into even smaller, three-student breakout rooms, each with a teacher to focus the lessons and games.

鈥淭his shows that we can actually teach kids online if we鈥檙e using the correct methodology, keeping them engaged, and they鈥檙e interacting socially with their peers and teachers,鈥 said , a research scientist at I-LABS and the study鈥檚 first author. 鈥淐ombining all of this made it successful.鈥

Children in both the Reading Camp and control groups took several standardized and non-standardized tests to assess knowledge of letters, sounds and words. The results showed that the Reading Camp participants improved in all of the reading skills measured, and their phonological awareness and knowledge of lowercase letters and sounds, in particular, more than the children in the control group.

鈥淔rankly, I had my doubts about whether 5-year-olds could learn to read online without a live tutor. But when I saw these 5-year-olds on Zoom laughing and encouraging each other to listen and hold up the right color egg, I was amazed. Their social connections to each other were obvious, and their learning was incredible. They called each other by name and seemed very eager to see each other on the screen,鈥 Kuhl said.

Researchers plan to hold additional online reading camps, and to add brain scans prior to and after the camps to evaluate how learning to read affects brain development.

The study was funded by the Bezos Family Foundation, the Overdeck Family Foundation, and the Petunia Charitable Fund.

Additional co-authors were Suzanne Ender, Liesbeth Gijbels, Hailley Loop, Julia Mizrahi and Bo Woo, all of I-LABS.

Scientists identify overgrowth of key brain structure in babies who later develop autism /news/2022/03/29/scientists-identify-overgrowth-of-key-brain-structure-in-babies-who-later-develop-autism/ Tue, 29 Mar 2022 18:12:46 +0000 /news/?p=77900 The amygdala is a small structure deep in the brain important for interpreting the social and emotional meaning of sensory input 鈥 from recognizing emotion in faces to interpreting fearful images that inform us about potential dangers in our surroundings. Historically, the amygdala has been thought to play a prominent role in the difficulties with social behavior that are central to autism.

Researchers have long known the amygdala is significantly larger in school-age children diagnosed with autism, but it was unknown precisely when that enlargement occurs. Now, for the first time, researchers from the Infant Brain Imaging Study (IBIS) Network, which includes the 天美影视传媒, used magnetic resonance imaging (MRI) to demonstrate that the amygdala grows too rapidly in infancy. Overgrowth begins between 6 and 12 months of age, before the characteristics of autism fully emerge, potentially enabling the earliest identification of this condition.

The , published March 25 in the American Journal of Psychiatry, is the first to document amygdala overgrowth before autism appears clinically. The research was conducted through the IBIS Network, a consortium of 10 universities in the United States and Canada.

The study also showed that increased growth of the amygdala in infants who were later diagnosed with autism differed markedly from brain-growth patterns in babies with another neurodevelopmental disorder, fragile X syndrome, where no differences in amygdala growth were observed.

The research found that infants with fragile X syndrome already exhibit cognitive delays at 6 months of age. Infants who will later be diagnosed with autism do not show any deficits in cognitive ability at 6 months but have a gradual decline in cognitive ability between 6 and 24 months, the age when they were diagnosed with Autism Spectrum Disorder in this study.

鈥淲e also found that the rate of amygdala overgrowth in the first year is linked to the child鈥檚 social deficits at age two,鈥 said first author , assistant professor of psychiatry and neuroscience at the University of North Carolina Chapel Hill and faculty of the Carolina Institute for Developmental Disabilities. 鈥淭he faster the amygdala grew in infancy, the more social difficulties the child showed when diagnosed with autism a year later.鈥

by the IBIS team and others 听revealed that even though the social deficits that are a hallmark of autism are not present at 6 months of age, infants who go on to develop autism have altered attention to visual stimuli in their surroundings in the first year of life. The authors hypothesize that these early alterations with processing visual and sensory information may place increased stress on the amygdala, leading to its overgrowth.

鈥淲e are getting closer to understanding why autism occurs by learning more about brain growth alterations early during development, in this case how amygdala growth may be influenced by early sensory processing difficulties and, conversely, how amygdala growth alterations may influence a baby鈥檚 interaction with their environment,鈥 said , professor of radiology in the UW School of Medicine and an adjunct professor of bioengineering.

As part of the IBIS Network, the UW has been involved in several studies over the years. In 2019, the multicenter research team received a five-year, $9.5 million grant from the National Institute of Mental Health to continue their efforts to determine whether brain imaging can help detect infants who are likely to go on to develop autism spectrum disorder.

The UW Autism Center established an infant clinic in 2017, which provides evaluations for infants and toddlers and support for caregivers. Just as with older children with autism, psychologists and behavior analysts help create treatment plans with clinic- and home-based activities.

The Autism Center has also evaluated sleep issues as part of both long-term research studies and in the clinical setting. A 2020 study led by the UW was the first to show links between growth in the hippocampus 鈥 a key part of the brain for learning and memory — and sleep problems in infants who are later diagnosed with autism.

鈥淚t is so exciting see the work of so many dedicated families and researchers over the last 16 years come together to reveal things we have never known before about how autism develops,鈥 said , director of the UW Autism Center. 鈥淏y assessing and monitoring development in infants who have a family history of autism, we can learn better ways to support caregivers and work on finding innovative ways to help infants reach their fullest potential.鈥

The new study was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institute of Environmental Health Sciences, and National Institute of Mental Health, Autism Speaks and the Simons Foundation.

Along with the UW and UNC at Chapel Hill, other participating institutions are Children鈥檚 Hospital of Philadelphia, the University of Pennsylvania, the University of Minnesota, New York University, the University of Texas at Dallas, Washington University, the University of Alberta and McGill University. The imaging sites are located in Seattle, St. Louis, Philadelphia, Chapel Hill, North Carolina, and Minneapolis-St. Paul.

Sleep difficulties in the first year of life linked to altered brain development in infants who later develop autism /news/2020/05/07/sleep-difficulties-in-the-first-year-of-life-linked-to-altered-brain-development-in-infants-who-later-develop-autism/ Thu, 07 May 2020 13:00:35 +0000 /news/?p=67886

Infants spend most of their first year of life asleep. Those hours are prime time for brain development, when neural connections form and sensory memories are encoded.

But when sleep is disrupted, as occurs more often among children with autism, brain development may be affected, too. New research led by the 天美影视传媒 finds that sleep problems in a baby鈥檚 first 12 months may not only precede an autism diagnosis, but also may be associated with altered growth trajectory in a key part of the brain, the hippocampus.

In a published May 7 in the American Journal of Psychiatry, researchers report that in a sample of more than 400 6- to 12-month-old infants, those who were later diagnosed with autism were more likely to have had difficulty falling asleep. This sleep difficulty was associated with altered growth trajectories in the hippocampus.

鈥淭he hippocampus is critical for learning and memory, and changes in the size of the hippocampus have been associated with poor sleep in adults and older children. However, this is the first study we are aware of to find an association in infants as young as 6 months of age,鈥 said lead author , a postdoctoral researcher at the UW Autism Center.

As many as 80% of children with autism spectrum disorder have sleep problems, said , director of the and senior author on the study. But much of the existing research, on infants with siblings who have autism, as well as the interventions designed to improve outcomes for children with autism, focus on behavior and cognition. With sleep such a critical need for children 鈥 and their parents 鈥 the researchers involved in the multicenter , or IBIS Network, believed there was more to be examined.

鈥淚n our clinical experience, parents have a lot of concerns about their children鈥檚 sleep, and in our work on early autism intervention, we observed that sleep problems were holding children and families back,鈥 said Estes, who is also a UW professor of speech and hearing sciences.

Researchers launched the study, Estes said, because they had questions about how sleep and autism were related. Do sleep problems exacerbate the symptoms of autism? Or is it the other way around 鈥 that autism symptoms lead to sleep problems? Or something different altogether?

鈥淚t could be that altered sleep is part-and-parcel of autism for some children. One clue is that behavioral interventions to improve sleep don鈥檛 work for all children with autism, even when their parents are doing everything just right. This suggests that there may be a biological component to sleep problems for some children with autism,鈥 Estes said.

To consider links among sleep, brain development and autism, researchers at the IBIS Network looked at MRI scans of 432 infants, surveyed parents about sleep patterns, and measured cognitive functioning using a standardized assessment. Researchers at four institutions 鈥 the UW, University of North Carolina at Chapel Hill, Washington University in St. Louis and the Children鈥檚 Hospital of Philadelphia 鈥 evaluated the children at 6, 12 and 24 months of age and surveyed parents about their child鈥檚 sleep, all as part of a longer questionnaire covering infant behavior. Sleep-specific questions addressed how long it took for the child to fall asleep or to fall back asleep if awakened in the middle of the night, for example.

At the outset of the study, infants were classified according to their risk for developing autism: Those who were at higher risk of developing autism 鈥 about two-thirds of the study sample 鈥 听had an older sibling who had already been diagnosed. Infant siblings of children with autism have a 20 percent chance of developing autism spectrum disorder 鈥 a much higher risk than children in the general population.

A 2017 study by the IBIS Network found that infants who had an autistic older sibling and who also showed expanded cortical surface area at 6 and 12 months of age were more likely to be diagnosed with autism compared with infants without those indicators.

In the current study, 127 of the 432 infants were identified as 鈥渓ow risk鈥 at the time the MRI scans were taken because they had no family history of autism. They later evaluated all the participants at 24 months of age to determine whether they had developed autism. Of the roughly 300 children originally considered 鈥渉igh familial risk,鈥 71 were diagnosed with autism spectrum disorder at that age.

Those results allowed researchers to re-examine previously collected longitudinal brain scans and behavioral data and identify some patterns. Problems with sleep were more common among the infants later diagnosed with autism spectrum disorder, as were larger hippocampi. No other subcortical brain structures were affected, including the amygdala, which is responsible for certain emotions and aspects of memory, or the thalamus, a signal transmitter from the spinal cord to the cerebral cortex.

The UW-led sleep study is the first to show links between hippocampal growth and sleep problems in infants who are later diagnosed with autism.

Other studies have found that 鈥渙vergrowth鈥 in different brain structures among infants who go on to develop those larger structures has been associated, at different stages of development, with social, language and behavioral aspects of autism.

While the UW sleep study found a pattern of larger hippocampal volume, and more frequent sleep problems, among infants who went on to be diagnosed with autism, what isn鈥檛 yet known is whether there is a causal relationship. Studying a broader range of sleep patterns in this population or of the hippocampus in particular may help determine why sleep difficulties are so prevalent and how they impact early development in children with autism spectrum disorder.

鈥淥ur findings are just the beginning 鈥 they place a spotlight on a certain period of development and a particular brain structure but leave many open questions to be explored in future research,鈥 MacDuffie said.

A focus on early assessment and diagnosis prompted the UW Autism Center to establish an infant clinic in 2017. The clinic provides evaluations for infants and toddlers, along with psychologists and behavior analysts to create a treatment plan with clinic- and home-based activities 鈥 just as would happen with older children.

The UW Autism Center has evaluated sleep issues as part of both long-term research studies and in the clinical setting, as part of behavioral intervention.

鈥淚f kids aren鈥檛 sleeping, parents aren鈥檛 sleeping, and that means sleep problems are an important focus for research and treatment,鈥 said MacDuffie.

The authors note that while parents reported more sleep difficulties among infants who developed autism compared to those who did not, the differences were very subtle and only observed when looking at group averages across hundreds of infants. Sleep patterns in the first years of life change rapidly as infants transition from sleeping around the clock to a more adult-like sleep/wake cycle. Until further research is completed, Estes said, it is not possible to interpret challenges with sleep as an early sign of increased risk for autism.

The study was funded by the National Institutes of Health, Autism Speaks and the Simons Foundation. , professor of radiology at the UW School of Medicine and , research scientist at the UW Autism Center, were co-authors. Additional co-authors, all at IBIS Network institutions, were , , and at the University of North Carolina at Chapel Hill; , now at the James S.
