Abstract

Motor neuron disease (MND) and frontotemporal dementia often appear together. We report on a 74-year-old woman who presented with a 18-month history of memory deterioration and MND. Her initial clinical diagnosis was probable Alzheimer's disease (AD) coexisting with MND. We conducted 11C-labeled Pittsburgh Compound-B positron-emission tomography (11C-PIB PET) to discriminate AD from other degenerative dementia, the results from which were negative for amyloid deposition.
