Diet, central nervous system, and aging. 1979

L D Lytle, and A Altar

A variety of morphological, structural, and chemical changes have been described in the central nervous systems of aging humans and animals. Brain size and volume decline during senescence, and the brain atrophy is accompanied by changes in the number, size, and ultrastructural characteristics of nerve and glial cells. Moreover, 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 central nervous system structure.

UI MeSH Term Description Entries
D009435 Synaptic Transmission The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES. Neural Transmission,Neurotransmission,Transmission, Neural,Transmission, Synaptic
D009451 Neuroeffector Junction The synapse between a neuron (presynaptic) and an effector cell other than another neuron (postsynaptic). Neuroeffector junctions include synapses onto muscles and onto secretory cells. Junction, Neuroeffector,Junctions, Neuroeffector,Neuroeffector Junctions
D009457 Neuroglia The non-neuronal cells of the nervous system. They not only provide physical support, but also respond to injury, regulate the ionic and chemical composition of the extracellular milieu, participate in the BLOOD-BRAIN BARRIER and BLOOD-RETINAL BARRIER, form the myelin insulation of nervous pathways, guide neuronal migration during development, and exchange metabolites with neurons. Neuroglia have high-affinity transmitter uptake systems, voltage-dependent and transmitter-gated ion channels, and can release transmitters, but their role in signaling (as in many other functions) is unclear.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D001923 Brain Chemistry Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states. Chemistry, Brain,Brain Chemistries,Chemistries, Brain
D002395 Catecholamines A general class of ortho-dihydroxyphenylalkylamines derived from TYROSINE. Catecholamine,Sympathin,Sympathins
D004032 Diet Regular course of eating and drinking adopted by a person or animal. Diets
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000368 Aged A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available. Elderly
