Information About Developmental Disabilities
The term developmental disability refers to a severe and chronic disability that is attributable to a mental or physical impairment that begins before an individual reaches adulthood. These disabilities include intellectual disability, cerebral palsy, epilepsy, autism, and disabling conditions closely related to intellectual disability or requiring similar treatment.
For an individual to be assessed in California as having a developmental disability, the disability must begin before the individual's 18th birthday, be expected to continue indefinitely and present a substantial disability. For further information, see Who Is Eligible For Services or contact your local regional center.
