We have recently encountered a patient with progressive dementia and parkinsonism beginning at the age of 68 years and developing for 2 years. Pathological examination revealed severe degeneration exclusively in the substantia nigra with absence of Lewy bodies and neurofibrillary changes. The features of this case are reported and discussed.
