Neurochemical changes in the aging process: Implications in medication in the elderly

Aging is an inevitable process in human development, which follows a time course that can be delayed, or hastened, by lifestyles, diseases and events. The factors that affect the aging process can be delayed, but not prevented. This paper evaluates the neurochemical changes in the aging process and their relevance in the modality of elderly medication. For clarity and understanding of the relevant neurobiochemical process and effects, the neuroanatomical, physiological, and neurobehavioral changes are reviewed as they relate to medication in the elderly.
