Over 5 million Americans are estimated to have a developmental disability.
According to the DD Act, the term developmental disability means a severe, chronic disability that occurs before an individual is 22 that is likely to continue indefinitely, and results in substantial functional limitations in three or more of the following areas of major life activity:
- receptive and expressive language
- capacity for independent living
- economic self-sufficiency
- These impairments require the individual to sustain lifelong or extended supports or assistance. Diagnosed conditions may include autism, Down syndrome, cerebral palsy, or spina bifida.
