title: Dementia pugilistica with clinical features of Alzheimer's disease.
abstract: A 61-year-old ex-boxer presented with a three-year history of progressive memory decline. During a seven-year follow-up period, there was a continuous cognitive decline, very similar to that usually observed in Alzheimer's disease. Parkinsonian, pyramidal or cerebellar signs were conspicuously absent. Neuropathological examination revealed the typical features of dementia pugilistica: cavum septi pellucidi with multiple fenestrations, numerous neurofibrillary tangles in the cerebral isocortex and hippocampus (and rare senile plaques). Immunohistochemistry disclosed a high number of tau protein deposits and scarce beta-amyloid staining. This case shows that dementia pugilistica may present with clinical features practically undistinguishable from Alzheimer's disease.
