What this research studies

We want to learn more about how the brains and thinking abilities of adults with autism spectrum disorder (ASD) change as they age, particularly after 45. We're looking for new insights into how brain structure and function, as well as memory and behavior, might shift over time. Our goal is to identify factors that could lead to challenges as people with ASD get older, such as changes in brain chemistry. We will follow groups of adults with and without ASD over several years, using brain scans and various assessments to understand these changes.

Who could benefit from this research

Good fit: Ideal participants are adults with autism spectrum disorder or typically developing adults between 40 and 70 years old who are willing to participate in long-term follow-up.

Not a fit: Patients outside the specified age range or those not interested in long-term observational participation may not directly benefit from this specific opportunity.

Why it matters

Potential benefit: This work could help us better understand the aging process in people with ASD, leading to earlier support and improved care strategies for older adults.

How similar studies have performed: While some cross-sectional findings exist, this project is novel in its longitudinal approach to understanding aging in ASD, making it a pioneering effort.
