Reported changes in neurotransmitter systems with aging in human and animal brain are briefly reviewed. The effects of age appear to vary from region to region in brain, as well as from system to system. Considerable evidence is available that dopaminergic activity decreases with age, particularly in the striatum and nucleus accumbens; this loss may be important to age-related losses in agility and increases in the incidence and severity of tardive dyskinesia. Lesser, but still convincing, evidence indicates decreases with age in noradrenergic, GABAergic and cholinergic systems, with the most marked effects being found, respectively, in the hypothalamus, thalamus and cortex-hippocampus. The cortical and hippocampal losses in cholinergic activity are markedly accentuated in senile dementia of the Alzheimer type and are probably related to memory defects in aging and dementia.</li><li>2.2.
