Parkinson's disease (PD) in elderly is mainly associated with motor symptoms. However non-motor symptoms occupy significant part of PD and their prevalence is 20%-60%; visual hallucinations are especially frequent. Manifestation of psychosis is 3%-4% in early stages of PD. More than 50% od existing psychiatric disorders are not identified in clinical practice. In order to identify psychotic symptoms clinicians need to reject other mental disorders, whose clinical picture can be similar: severe depression with psychosis, dementia, delirium and other organic diseases including brain tumors, circulatory diseorders, endocrinal disturbances and medications' impact. Detecting of the psychosis allows choosing an effective strategy of psychopharmacologic treatment. A positive clinical effiect was achieved after the treatment with antipsychotic drug which improved patient's mental state and didn't impair parkinsonism. I am presenting clinical case of a women (58), whose PD manifested with psychotic symptoms, so evaluation of her mental and neurological state was handicap as well as differential diagnosis. The aim of clinical case report was to highlight the importance of careful attention to differential diagnosis of non-motor symptoms.
