Developmental Disabilities

Developmental Disabilities (DD)

Developmental disabilities (DD), as defined in federal law, is a severe, chronic, often lifelong disability that causes substantial limitations in several major life activities such as: self care, receptive and expressive language, learning, mobility, self-direction, the capacity for independent living, and economic self-sufficiency. It is attributable to a mental, emotional, sensory, and/or physical impairment that is apparent before the age of twenty-two. People with developmental disabilities often need a combination of special services, support and other assistance that is likely to continue indefinitely. People with developmental disabilities constitute the most severely under-served population in the Commonwealth. Developmental disabilities include: intellectual disabilities, autism, epilepsy, cerebral palsy, down syndrome and other neurological conditions.


There are many organizations established to assist people with developmental disabilities and their families. As a result of the federal Developmental Disabilities Act, re-authorized in 1990, each state has a planning council, a protection & advocacy organization, and at least one University Center for Excellence in Developmental Disabilities (UCEDDs). All are focused on the needs of individuals with developmental disabilities. In addition, there are many disability specific organizations providing info, advocacy and, in some cases, direct services to people with developmental disabilities.  United Cerebral Palsy Associations and Head Injury Associations are examples of such organizations.

University Centers for Excellence in Developmental Disabilities

Since 1963, University Centers for Excellence in Developmental Disabilities Education, Research, and Service (UCEDD) have been working to accomplish a shared vision that foresees a nation in which all Americans, including Americans with disabilities, participate fully in their communities. Independence, productivity, and community inclusion are key components of this vision. Currently, sixty-seven UCEDDs in every state and territory are located in a university setting.
