The goal of the research was to investigate some non-motor disorders at patients with Parkinson disease (PD) and to determine their relations to the main manifestations of the disease. 68 patients with PD without dementia were studied. Duration of disease was 4 (2-6) years. The following scales were used: Modifed Fatigue Impact Scale (MFIS), Unifed Parkinson Disease Rating Scale (UPDRS, part 3), Hospital Anxiety and Depression Scale (HADS), A. M. Veyn Questionnaire for autonomic disturbances and the Epworth Sleepiness Scale (ESS). The results of this study have revealed the presence of emotional disorders, fatigue, autonomic dysfunction and dyssomnia at patients with PD. Non-motor symptom severity does not depend on age and sex of the patients, as well as the main motor symptoms of the disease. The relationships of the examined non-motor symptoms were revealed.
