Despite some publications on Parkinson’s disease prevalence in Bulgaria, its frequency in the country still remains uncertain. Earlier studies in Bulgaria were carried out on large population groups and were based on medical records without further diagnostic confirmation. The aim of the present study was to perform an epidemiological investigation on Parkinson’s disease in Bulgaria, using strict diagnostic criteria in an attempt to obtain a more accurate estimate of its frequency in this country. We studied the prevalence of Parkinson’s disease in two small regions of Bulgaria. Cases were ascertained by the medical records and confirmed by personal examination. The prevalence of Parkinson’s disease was found to be 164.2 per 100,000 with 47 cases in the first region and 169.8 per 100,000 with 155 cases in the second region. Based on two small population studies, the prevalence ratio in different parts of Bulgaria is not significantly different and is similar to other European countries.
