Piribedil in the treatment of mental and cognitive impairments in Parkinson's disease

Abstract

Mental and cognitive impairments are common non-motor symptoms of Parkinson's disease (PD), which affect more than half of patients at various stages of the disease. These symptoms significantly reduce the quality of life of patients and their relatives. The article reflects the features of the pathogenesis of mental and cognitive impairments in PD, as well as the role of the dopamine receptor agonist piribedil in their correction. Piribedil, having a good safety and tolerability profile, and also, presumably, having a positive effect on such non-motor symptoms of PD as increased daytime sleepiness, depression, apathy, anhedonia and cognitive functions, can significantly improve the quality of life of patients and their adherence to therapy.
