The APA task force on psychiatric services to mentally retarded and developmentally disabled adults estimated that the prevalence of mental disorders is significantly higher among mentally retarded persons than in the general adult population, ranging between 33 and 70 percent for various disorders (
+10). Many individuals have coexisting problems such as language disorders, impaired mobility, and hearing or visual impairments that may worsen with advancing age. Persons with brain injury who have additional impairments can lose more communication skills over time and become increasingly isolated. This progressive loss of control over their environment is a significant contributing factor to behavioral dysfunction. Behavioral disorders are worsened when others have inappropriate expectations and when attention to the unique nature and extent of each disability is lacking.
In the 1970s, successful advocacy efforts by parents of persons with mental retardation, which were motivated by the desire to distinguish mental retardation from mental illness and avoid the stigma of mental illness, caused a separation of funding resources for mental health and mental retardation services. This dichotomy also is reflected in the training of psychiatry and primary care residents. The guidelines for training programs in psychiatry and family medicine developed by the Accreditation Council of Graduate Medical Education do not specifically mention mental retardation. APA's 1995 curriculum guide in psychiatry and mental retardation (
+12) has not yet been integrated into residency training programs.
Behavioral problems are often not assessed or managed with the expertise required. Hence, developmentally disabled persons who are dually diagnosed or behaviorally disturbed often do not have the benefit of state-of-the-art use of anticonvulsants, newer atypical antipsychotics, and antidepressants.
However, the APA task force report described several successful models of service, training, and research, including a university-affiliated model in Boston and a nationally funded inpatient center at the University of Nebraska (
+10). More than ten years ago, the need for curricula on aging and developmental disabilities began to be emphasized in institutions of higher learning (
+13). More recently, Menolascino and Fleisher (
+14) described a curricular model for the management of dually diagnosed persons, emphasizing special diagnostic skills, the important role of the caregiver, and preparation of skilled personnel. A program on aging in the developmentally disabled population developed by the department of psychiatry at Queen's University in Kingston, Ontario, includes a year-long fellowship in coordination with the department of family medicine (
+15).
A community-based crisis intervention model, funded through the New York State Office of Mental Retardation and Developmental Disabilities, has been developed in Rochester, New York (
+16). Behavioral interventions include operant care plans to reinforce desired behaviors and staff training in instituting the plans. The program has increased the capability of staff and families to manage problem behaviors and has enhanced coordination of care. Another New York State project, carried out by Peoples, Incorporated, of Western New York, included programming for elderly developmentally disabled persons in a specialized nursing home setting. Enhanced quality of life in late life is more likely in such a specialized setting than in general skilled nursing facilities.
Natural progressions in life such as changes in work situations, retirement, change of living arrangements, and financial planning for later life have been dealt with inconsistently. Often legal means must be used to achieve equity for elderly developmentally disabled persons. Court cases have addressed the rights of mentally retarded people to education, treatment, and just compensation. Legal concerns, finances, advanced health care directives, and alternative living situations must be discussed and arranged with an emphasis on each person's autonomy, dignity, and cultural milieu.
Many persons with developmental disabilities live with their families. As both the developmentally disabled person and family members age, the need for respite care services, long-term financial planning, guardianship arrangements, and determination of future residential options increases. The American Association of Retired Persons (AARP) has identified several agencies that can be contacted for assistance with these issues (see box above).

Mengel and associates (
+23) described a support and education group formed for aging parents who served as caregivers. An interesting observation was the change in interaction between parent and child as both aged. They described situations in which the adult child helped to educate the parent about aging and mutual needs for assistance; sometimes the parent needed more care than the aging child, and the child was able to offer assistance. Another positive outcome of this group's experience was enhanced linkages between local service networks for the developmentally disabled and for the elderly populations.
Efforts to bring the aging developmentally disabled and mentally handicapped population into the mainstream of professional training and services are encouraging. The impact of managed care on the provision and quality of services for aging developmentally disabled persons who cannot advocate for themselves must be closely researched and monitored so that public funds are used to promote comprehensive and continuous care for this vulnerable population.•
