The NNA Program fosters extramural research and training to further the understanding of the aging process in the structure and function of the nervous system. An area of special emphasis is brain-behavior relationships. An important component of this Program is the support of basic, clinical, and epidemiological studies of Alzheimer's disease and related dementias of aging.
The NNA Program is composed of three branches: Neurobiology, Neuropsychology, and Dementias of Aging. Overall, the Program supports a broad spectrum of research aimed at elucidating how the central nervous system and behavior are affected by normal as well as pathological aging. The basic theme throughout the Program is understanding the aging nervous system in order to minimize declines and foster improvements in the quality of life of the older population.
