Abstract

Old age involves significant physiological and mental changes. Of particular importance in the aging process are changes in higher nervous activity, accompanied by a violation of higher mental functions of varying severity and a reduced level of resistance to stress.

There are various attempts to improve cognitive function in the elderly. One of the promising areas in the field of psychological correction is training using neurofeedback.

The cognitive evoked potentials are objective indicators of the state of cognitive functions and can be used to study their disorders. The component of cognitive evoked potentials is a positive wave. The parameters that characterize it are the latency P3 (ms) and the amplitude N2-P3 (μV). It is believed that this component is most closely related to the cognitive processes of perception, attention, memory. The aim of our study was to identify changes in the cognitive evoked potentials before and after the application of neurofeedback training.

The study involved 32 elderly women, of whom two groups of 16 persons were formed – "experimental" and "placebo". The experimental group participated in 15 sessions of the neurofeedback training. Representatives of the placebo group believed that they participated in the training,instead, this was a sham neurofeedback training procedure.

The study found a significant reduction in P3 latency after the next step of neurofeedback training. In addition, the neurofeedback training displays the values of the values of the peak interval in the experimental group. No statistically significant differences in R300 latency were found in the placebo groups surveyed.
