Maryland’s Definition of Developmental Disability


Maryland State Law defines developmental disability as a severe chronic disability that:

  1. is attributable to a physical or mental impairment, other than the sole diagnosis of mental illness, or to a combination of mental and physical impairments; 
  2. is manifested before the individual attains the age of 22; 
  3. is likely to continue indefinitely; 
  4. results in the inability to live independently without external support or continuing and regular assistance; and, 
  5. reflects the need for a combination and sequence of special, interdisciplinary, or generic care, treatment, or other services that are planned and coordinated for that individual.
