Age-specific changes in cognitive function

Abstract

Currently, the number of cases of pathological aging of the central nervous system, represented by a violation of cognitive functions, is increasing. But there is a social request to prolong the physical and mental activity of older people. The study of the dynamics of cognitive aging is timely and relevant. The article contains a report on a cohore non-repeating study of higher brain functions at various age periods. 148 people involved. Their age is 27 -74 years. They are right handed. We applied the screening neuropsychological method. Statistical data processing was performed using SPSS Statistics 17.0 (Mann-Whitney U-test). The dynamic heterogeneity of the cognitive profile during aging was revealed. The deterioration in the performance of the graphomotor test was the most age-specific. In older study participants, a decrease in the visual gnosis test correlated with a decrease in non-verbal intelligence. The decrease in executive functions correlated with the growth of neurodynamic disorders in elderly study participants. The results obtained are useful for differentiating normative and pathological aging of the central nervous system.
