Diet, central nervous system, and aging

Lytle, Loy D. | Altar, Anthony
A variety of morphological, structural, and chemical changes have been described in the central nervous system of aging humans and animals. Brain size and volume decline during senescence; the brain atrophy is accompanied by changes in the number, size, and ultrastructural characteristics of nerve and glial cells. Recent evidence suggests that the ability of central nervous system cells to communicate with one another via the release of neurotransmitter compounds might be impaired in the elderly. Nutritional factors may play important roles in the aging process of the central nervous system by influencing brain neurotransmission, or by accelerating or retarding geriatric changes in the central nervous system structure. Many of the changes thought to be caused by aging might possibly result indirectly from other geriatric disease processes. Further research is needed on the functional importance of aging alterations in the structure and chemistry of the central nervous system.
