Abstract
A 62-year-old man presented with a one-year history of word finding difficulty, impaired single word comprehension and personality changes including aggression, apathy and eating change. Brain MRIs showed severe atrophy in the left anterior temporal lobe. The clinical syndromic diagnosis was semantic variant primary progressive aphasia. He died at age 70 of pneumonia. At autopsy, transactive response DNA-binding protein (TDP) immunoreactive long dystrophic neurites were predominantly found in the cerebral cortices, which were compatible with frontotemporal lobar degeneration-TDP type C pathology.
