The development of brain imaging techniques has helped us understand emotion, intellectual and developmental disabilities, and neurodegenerative diseases in ways we could not before.
Autism spectrum disorder (ASD) is an intricate and complicated diagnosis. The spectrum of presentations and severity is as expansive as the theorized causes. Autism’s complexity and breadth of impacts on a person’s life means that it has a multitude of facets to investigate.
Recent studies suggest that older adults with ASD may have shorter life expectancies and more physical and mental health difficulties than the general population. A new, landmark longitudinal study of aging and autism hopes to better understand how differences in aging may impact the health outcomes of individuals with ASD.
The American Academy of Child and Adolescent Psychiatry (AACAP) has awarded Janet E. Lainhart, MD, a pediatrician, psychiatrist, professor in the School of Medicine and Public Health at the University of Wisconsin-Madison, and a Waisman Center investigator, the 2021 AACAP George Tarjan, MD, Award for Contributions in Developmental Disabilities.
What images come to mind when you hear the phrase social brain? Do you think of children running around on a playground laughing together? Do you think of problem solving or imagine colorful brain scans? Do you think of autism? These are the questions that inspired a breadth of autism research that was recently evaluated by a team of Waisman scientists and compiled into a new literature review.
One of the goals of the study is to discover how genetic variations in young people with ASD are related to brain changes that lead to clinical symptoms of the disorder, such as impaired social interaction and repetitive behaviors.
“If you think about it, in between genes and clinical symptoms [of ASD] are changes in brain development,” says Lainhart. “Genes first impact brain development, and as a result of changes in how the brain develops, there are clinical manifestations of what we recognize as ASD.”
The thalamus is a key sensorimotor relay area that is implicated in autism spectrum disorder (ASD). However, it is unknown how the thalamus and white-matter structures that contain thalamo-cortical fiber connections (e.g., the internal capsule) develop from childhood into adulthood and whether this microstructure relates to basic motor challenges in ASD.

A new study by Waisman Center investigators Andy Alexander, PhD, professor of medical physics and psychiatry, Janet Lainhart, MD, professor of psychiatry and Brittany Travers, PhD, assistant professor of kinesiology, indicates a nerve bundle at the base of the brain is structurally compromised in people with autism. The study was recently featured by the Simons Foundation Autism Research Initiative.
March 28, 2014 Lindsey Tanner, Associated Press A small study that examined brains from children who died found abnormal patterns of cell growth in autistic children. The research bolsters evidence that something before birth might …
