“We need more research to be able to understand how to treat core symptoms of autism in this population, as well as common associated symptoms such as anxiety, compulsive behaviors and agitation,” said Jeremy Veenstra-VanderWeele, M.D., assistant professor of Psychiatry, Pediatrics and Pharmacology and Vanderbilt Kennedy Center investigator. “Individuals, families and clinicians currently have to make decisions together, often in a state of desperation, without clear guidance on what might make things better and what might make things worse, and too often, people with autism spectrum disorders end up on one or more medications without a clear sense of whether the medicine is helping.”
