In a hospital-based study we investigated the prevalence of Parkinson’s disease among inhabitants of the Vilnius city, the capital of Lithuania. The study group was selected from patients who were diagnosed with Parkinson’s disease during the time frame of 1978-2005. Patients’ time of diagnosis were based on the data of dispensary cards, registration journals and/or other documentation. A questionnaire and Mini Mental State Examination provided data for analysis on the conditions of the patients. The prevalence of Parkinson’s disease in Vilnius is 1.32/1000 inhabitants and is higher in men than in women (p < 0.05). The age of Parkinson’s disease onset in men and women is the same (63.77 ± 0.70 years). The rigidity-tremor form of Parkinson’s disease is the most frequent (76.8% of all cases). The PD prevalence rate in Vilnius inhabitants are close to the mean levels observed in studies made in Finland, Austria, Germany. The prevailing form of Parkinson’s disease is rigidity-tremor.
