This study will help us develop a better understanding of autistic adults/adults with Autism Spectrum Disorder (ASD) by exploring aging and brain function.

Call to action

Are you an autistic adult/adult with ASD? Consider participating in our study.

Who can participate

We are looking for adults:

  • 40 years and older
  • Have an autism diagnosis
  • With normal or corrected-to-normal vison and hearing


We are looking for neurotypical adults:

  • 40 years and older
  • No history of severe mental health disorders or developmental disorders
  • No first-degree family members with Autism Spectrum Disorder
  • Taking no psychotropic medications

Funding agency

Canadian Institute of Health Research (CIHR)

What's involved

  • You will be asked to answer questionnaires, undergo cognitive assessments, and have brain scans
  • Participation involves two sessions- one initial session and another after 3-4 years
  • Each session will take approximately 2 days.
  • You may also provide a blood sample for genetic analysis (optional)


What are the benefits of participating?

Not enough is known about the aging process in those with autism. By participating you will help us understand how aging happens so that we can develop better supports for autistic adults.

Participants will receive $100 per study session as reimbursement. You can also request the results of your testing.
