title: [Familial Parkinson disease].
abstract: We report the clinical findings and the pedigree of 10 patients of a family from Blacos, a small village in the Soria province, who had Parkinson's disease and in whom secondary causes and other diseases such as essential tremor or OPCA, to be considered in the differential diagnosis, had been ruled out. There were 6 males and 4 females with a mean age of 72.1 years; the mean age at the onset of symptoms was 67 years. All had the akinetic-rigid type of disease, and associated tremor was present in two cases. 90% were in functional classes I-II of the UPRS (United Parkinson's disease Rating Scale). 50% are presently receiving levodopa therapy, and only one has complications due to it. Emphasis is made on the etiological and pathogenetical heterogeneity of Parkinson's disease, where exogenous factors are probably superimposed to a genetic susceptibility.
