A study of quarter of a million people with autism, intellectual disabilities or both has found that their risk of developing symptoms associated with Parkinson’s disease is three times that in the general population.

The study is the largest of its kind, and warrants further investigation into the links between these conditions, researchers say. The findings were presented at the annual meeting of the International Society for Autism Research in Melbourne, Australia, on 16 May, and have not yet been peer reviewed.
