Feds set $100 mil for autism research


Researchers at the University of California, Davis; the University of California, Los Angeles; Yale University; Duke University; Emory University; George Washington University; the University of North Carolina, Chapel Hill; Drexel University; and Florida State University will receive their share of $100 million from the National Institutes of Health in order to investigate autism, the Disability Scoop reports.

“Autism spectrum disorder has myriad environmental, genetic, neurological, and behavioral components,” the advocacy site quoted Diana Bianchi, director of the NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development, as saying. The institute is one of five institutes funding the program. “These awards will allow us to understand how autism differs in girls versus boys, to develop earlier methods of screening, and to improve treatments based on specific symptoms.”

The Autism Centers of Excellence grants were launched in 2007 and are renewed every five years. This year’s recipients have aimed their research at evaluating universal autism screening in toddlers, testing parent coaching as an intervention for kids on the spectrum, looking for early signs of the developmental disorder in the brains of fetuses and newborns and addressing the transition to adulthood, and other issues.

NIH released the following info about the recipients’ research:

University of California, Davis
Improving ASD treatments based on symptoms

David G Amaral, PhD, and colleagues will continue their efforts to classify children into different subgroups, based on their symptoms, behavioral characteristics and genetic features and will attempt to develop behavioral and drug interventions appropriate for each subtype. The researchers have found that, by age 3, about 15 percent of boys with ASD have brains that are unusually large relative to the size of their bodies. These boys have a higher rate of regression, or loss of social and communications skills, and are more likely to have an intellectual disability. In contrast, at age 3, only 3 percent of girls with ASD had disproportionately large brains. The researchers plan to follow these children through childhood to determine if the structure of their brains differ from those of typically developing children.

University of California, Los Angeles
Tracing ASD symptoms to their origins

Susan Bookheimer, PhD, and colleagues will continue their efforts to look for clues into the nature of different subtypes of ASD by looking at areas of functioning often affected by the condition: sensorimotor processing, or how individuals process information from their senses; social motivation, the need to interact with others and be accepted by them; and social communication, the ability to use language and gestures for interactions with others. They will also test a medication to see if it can improve social functioning.

Yale University, New Haven, Connecticut
Examining development of functional brain connections

Katarzyna Chawarska, PhD, and colleagues will investigate brain connections in fetuses and newborns to identify early indicators of ASD. They will also determine if boys and girls with ASD differ in their brain circuity, with the aim of improving diagnosis and treatment. In addition, they will evaluate an intervention to improve social functioning in children at high risk for ASD.

Duke University, Durham, North Carolina
Understanding and potentially treating ASD-ADHD combination

An estimated 40 to 60 percent of people with ASD have attention deficit hyperactivity disorder (ADHD), which encompasses such symptoms as difficulty paying attention, problems controlling behavior and hyperactivity. Co-investigators Geraldine Dawson, PhD, and Scott Kollins, PhD, aim to learn how ADHD may influence the diagnosis and treatment of autism and plan to observe children who have ASD alone, ASD and ADHD, and ADHD alone and compare them to typically developing children. They will also test whether the stimulant medication used to treat ADHD will help children with both conditions.

Emory University, Atlanta
Studying social interaction to identify the early signs of ASD

Ami Klin, PhD, and colleagues will conduct studies on diagnosing autism early and developing the earliest possible interventions. The center will follow hundreds of infants from birth to 30 months, including those at high risk for ASD. They will study infant social interactions through measures of visual, vocal and brain development. Previously, the group showed that, when looking at videos of people speaking, infants who were later diagnosed with ASD had eye movements that differed from those of typically developing infants. More recently, the group found a genetic basis for those eye movements. When the children are 6 months of age, the researchers will test an intervention that will be easy for care givers to administer and tailored to each infant’s individual characteristics.

George Washington University, Washington, DC
Investigating how ASD differs between boys and girls

Girls are diagnosed with ASD much less frequently than boys. Kevin Pelphrey, PhD, and network colleagues will follow children through adolescence and into adulthood to understand differences in ASD risk between boys and girls and in how they each respond to interventions. They will also collaborate with self-advocates with ASD to understand how well their findings reflect real-life experiences. Together, they aim to uncover information that will help males and females living with ASD better manage the transition to adulthood.

University of North Carolina, Chapel Hill
Tracking brain development, behavior as ASD progresses

Joseph Piven, MD, and network colleagues previously compiled detailed information on brain development and behavior for 300 children at high risk for ASD and 100 children at low risk. The researchers found that brain growth of infants later diagnosed with ASD differed from that of typically developing children. With the new award, the researchers will follow these children through ages 7 to 10 years to determine how their brains change as they grow and the potential effects of ASD on learning and social development. Based on what they learn, they aim to develop interventions tailored to school-age children with ASD.

Drexel University, Philadelphia
Evaluating autism screening for all toddlers. Should every toddler be screened for ASD?

Diana L Robins, PhD, and network colleagues will conduct a randomized, controlled trial of 8,000 toddlers to determine if screening lowers the average age of ASD diagnosis, leads to earlier interventions and improves outcomes. Participating children from network clinics either will be evaluated at 18 months of age or be part of a group which will receive standard pediatric care. All children not screened at 18 months will be screened at 48 months and all children who are diagnosed with ASD will receive one year of behavioral therapy.

University of Florida, Gainesville
Testing parent coaching, home intervention for toddlers

Amy Wetherby, PhD, and network colleagues will test a two-part intervention designed to empower parents of children with ASD. The researchers will offer parents Problem Solving Education, a six-session intervention to help them access the services their children need and to adapt to caring for a child with special needs. Parents will also receive training in Early Social Interaction, which teaches them to support their children’s communication and social skills in everyday routines, activities and settings.
