      abstract = {This study examined lifetime medical and psychiatric  morbidity reported by caregivers of 2,917 autistic adults  participating in the US research cohort SPARK. Participants  were78.4% male, 47.3% had intellectual disability, and  32.1% had persistent language impairments. Childhood  language disorders (59.7%), speech/articulation problems  (32.8%), sleep (39.4%) and eating problems (29.4%), motor  delays (22.8%) and history of seizure (15.5%) were the most  frequently reported clinical features. Over two thirds  (67.2%) had been diagnosed with at least one psychiatric  disorder (anxiety disorders: 41.1%; ADHD: 38.7%). Compared  to verbally fluent participants, those with language  impairments had lower frequencies of almost all psychiatric  disorders. Female sex and older age were associated with  higher medical and psychiatric morbidity.},
