Autism Linked to Higher Parkinsonism Risk
Tap title to read story
Older adults diagnosed with autism face a significantly higher risk of developing Parkinson’s disease‑related movement disorders compared to the general population, a large study published in the journal Autism reports. Researchers analyzed Medicare and Medicaid claims data covering fifty‑seven million Americans aged forty‑five and older between two thousand seventeen and two thousand nineteen. Individuals on the spectrum, as well as those with intellectual disabilities, were diagnosed with parkinsonism at much higher rates than those without autism. The study excluded antipsychotic users and still found higher rates. In the general population control group, prevalence was one point five seven percent, rising to three point eight three percent among adults with autism alone, four point three two percent for intellectual disability alone, and four point eight six percent for both conditions.

Why it matters
Immediate US impact: Higher Parkinsonism rates may increase healthcare costs for autistic seniors. Possible long-term US impact: Long‑term monitoring could improve early intervention strategies for neurodivergent adults. Most affected groups: Autistic adults and those with intellectual disabilities face greatest risk. Reader priority: Clinicians should consider Parkinsonism screening for older autistic patients.
