• An increased prevalence of seborrheic dermatitis has previously been noted in idiopathic Parkinson's disease and in postencephalitic parkinsonism. Our study of 42 hospitalized patients with drug-induced parkinsonism and 47 hospitalized psychiatric patients without that disorder showed a statistically significant higher prevalence of clinically diagnosed seborrheic dermatitis in the group with drug-induced parkinsonism (59.5% v 15%). To our knowledge, this is the first report of an increased prevalence of seborrheic dermatitis with drug-induced parkinsonism.
