An overview of neuropsychiatric disturbances in the elderly

In no other period of life than old age do neurophysiologic alterations seem to affect behavior and cognition so significantly. Consequently, the relationship between neurology and psychiatry remains substantial when attempts are made to understand and deal with the many problems of aging. This study concerns improvement in the organization of such an approach to the neurologic and psychiatric problems of the elderly and to various interdisciplinary factors. Special consideration is given to changes in the central nervous system with aging, and to the differential diagnosis of dementia and pseudodementia.
