title: [Central mechanisms of the development of motor disorders during human aging].
abstract: This paper deals with the functional state of the brain and its descending regulatory influences on the brain stem-spinal formations in the elderly. The role of changes revealed in the formation of the clinical syndrome of age-related extrapyramidal insufficiency (EPI) as a risk factor of Parkinson's disease, has been shown. 274 apparently healthy subjects aged from 20 to 102 and 136 patients with early stages of Parkinson's disease were examined. The program of the neurophysiological investigation included: frequency-integrative analysis of EEG, visual and somatosensory potentials, simple motor reaction time and stimulating electroneuromyography (H reflex). It has been found that in aging and in Parkinson's disease one-directional changes in the CNS function that form age-related and pathologic EPI occur. The complex of neurophysiological indices is a reflection of the CNS influence on the underlying spinal formations, and it can be used for early diagnostics of the motor disorders in aging.
