This conference presentation describes New York State programs serving elderly mentally retarded (MR) and developmentally disabled (DD) persons. These service providers offer programming that is sensitive to the impact of the aging process, or provide the opportunity to access community aging programs, or a combination. Linkages are being developed among 13 aging and DD network groups. Three state offices are involved in the effort: the New York State Office for the Aging, the Office of Mental Retardation and Developmental Disabilities, and the Developmental Disabilities Planning Council. The Developmental Disabilities Project began in 1986 to test the feasibility of serving older developmentally disabled persons in congregate settings such as senior centers, nutrition sites, and social adult day care programs. The Project's three phases include studying problems in integrating older developmentally disabled persons into aging network programs and proposing strategies for reducing barriers, implementing a series of demonstrations to test integration strategies, and evaluating the relative effectiveness of the integration strategies and developing a how-to manual. Also described is a state-level Memorandum of Understanding which formalizes coordination and cooperation between the State Aging and MR/DD offices and establishes a model agreement that can be used to guide efforts at the county and regional level.
