Recent studies suggest a fascinating biological link between autism and Alzheimer’s. A 2025 Swedish study found that families with Alzheimer’s are more likely to have autistic children, hinting at shared genetic or environmental factors (Chang et al., 2025). Autistic adults may also face higher risks of early-onset Alzheimer’s—2.6 times more likely than the general population.

For families, this underscores the importance of monitoring cognitive health in aging autistic individuals. Caregivers can prepare by adapting home safety (e.g., grip strips, clear pathways) and exploring dementia care resources. While research is still evolving, these connections could reshape how we support both conditions.
