Organization of Psychogeriatric Services

Introduction Services specially concerned with mentally ill old people have arisen in response to changing needs and expectations in society. They take advantage of the knowledge gained in recent years of the epidemiology and natural history of the mental disorders of late life and their alleviation. The form of service adopted in a particular locality is usually shaped by patterns of care for the elderly provided by psychiatric and other services in the past. In this review we consider, first, the demographic background and epidemiology ofmental disorders in the elderly. Then we examine the way in which mentally ill old people use health and social services in general; and finally we discuss in some detail the history, planning and variety of those services which are specifically concerned with old people with mental disorders.
