How the autistic brain changes as people age

Brain Aging Across the Lifespan in Neurodevelopmental Disorders

NIH-funded research University of California at Davis · NIH-11235171

What this research studies

From my point of view, the team will use donated adult brains from people with autism who were clinically and genetically characterized to study how the brain changes with age. They will examine specific brain regions linked to memory and social behavior and identify which cell types show loss or damage. The researchers will measure markers of immune activity and inflammation in those cells to see whether inflammation may drive decline. Findings will be compared with non-autistic brains to pinpoint changes unique to adults with ASD.

Who could benefit from this research

Good fit: Adults with autism, especially middle-aged and older individuals, or those willing to join a brain-donation program after death, would be the ideal contributors to this work.

Not a fit: Children, people without ASD, and individuals who cannot or will not participate in brain-donation or clinical characterization programs are unlikely to gain direct benefit from this project in the near term.

Why it matters

Potential benefit: If successful, this work could reveal biological signs that predict or cause memory and thinking problems in adults with autism, helping guide future monitoring and treatments.

How similar studies have performed: Previous research has found brain and immune differences in children with autism and links between ASD and higher dementia risk, but detailed cell-specific aging changes in adult ASD brains remain largely untested and novel.
