[Confirmation of cortical lesions of progressive prosopagnosia by cerebral SPECT].
We present the case of a 78 year old man admitted to the hospital with progressive memory disorder. Neuropsychological examination showed inability to recognize familiar faces (prosopagnosia). MRI documented cortical atrophy, which did not explain the neurological deficit. CT did not show abnormalities. Most patients with prosopagnosia present brain atrophy, as they are more than 65 years old. Scanning by SPECT revealed hypoperfusion in the right parietotemporal region, which was worse in a later examination.
