Abstract
In Parkinson's disease (PD), among the clinical and symptomatic manifestations of the disease in recent years, attention has been increasingly paid to the so-called non-motor symptoms, that is, cognitive disorders. In PD, cognitive disorders can manifest themselves in the form of a decrease in executive, visual, and visuospatial activity and memory impairment from mild to severe dementia. Cognitive impairments of a subjective and objective nature are often found at the level of early and mild manifestations. In such situations, it is important to develop a strategy for predicting the progression of cognitive disorders and developing methods for their prevention. Long-term and multicenter studies conducted over the past 30-40 years have shown that after the diagnosis of PD, dementia develops after ten courses of the underlying disease. This, in turn, aggravates the already complex course of PD with a pronounced decrease in the quality of life of patients.
