Key Points

To compare the sociodemographic, developmental, functional, and medical characteristics of adults with intellectual disability with and without autism spectrum disorder.
Conducted a cross-sectional study of 329 adults with intellectual disability (170 with autism spectrum disorder, 159 without) at a tertiary outpatient clinic in Türkiye.
Assessed participants using standardized clinical evaluations, medical records, and caregiver reports.
Adults with autism were younger, more frequently male, had lower employment rates, and exhibited greater intellectual disability severity, poorer speech, higher support needs, and higher rates of developmental regression.
Non-autistic adults had higher rates of delayed walking, physical disability, immobility, congenital anomalies, and dysmorphic features.
Medical comorbidities, including epilepsy, hypothyroidism, cerebral palsy, and overall medical burden, occurred more frequently in adults without autism.
