title: [Role of the neuroendocrine system in aging].
abstract: The study involves 3 aspects of neuroendocrine control over the organism functions in aging: the decline in reproductive functions, the reduction of growth hormone secretion and the decrease in thymic functional activity and the altered relationship between neuroendocrine and immune systems. The role that an age-related decrease in dopamine and noradrenaline production by hypothalamic neurones plays in the above age changes in neuroendocrine control has been traced. The age-related decrease in functions of hypothalamic catecholaminergic neurones is apparently caused by the damaging effect of hormones (prolactin, glucocorticoids and, especially, estrogen), free radicals and toxins, both of the endogenous and exogenous origin. The restrained nutrition increases lifespan of the experimental animal owing to reduced "wear out" of the neuroendocrine system and organs and tissues that are controlled by this system.
