A 72-year-old right handed male presented with two and a half year history of communication difficulty. On a detailed speech and language examination, he had significant difficulty with propositional language, but well-preserved auditory comprehension, grammar, naming and repetition. There was no evidence of behavioral dyscontrol. MRI scan showed mild frontal lobe atrophy, and a fluorodeoxyglucose PET scan showed left lateral frontal hypometabolism. His profile was most consistent with the clinical entity known as dynamic aphasia. The detailed speech and language, neurological, neuropsychological and neuroimaging testing sheds light on the features of primary progressive dynamic aphasia.
