Abstract:
A subgroup of patients with progressive degenerative dementia that begins with higher visual dysfunction has been referred to as posterior cortical atrophy (PCA). A 55-year-old woman presented with progressive visual disturbance for 4 years, which was followed by geographical disorientation, impairment of writing and calculation, and memory distur-bance. Neuropsychological deficits were characterized by Balint syndrome, visuospatial dysfunction, prosopagnosia, Gerstmann syndrome and apraxia. Brain MRI showed mild diffuse atrophy. F18-FDG-PET disclosed bilateral occipi-totemporoparietal hypometabolism, more pronounced on the right. Biopsy from right temporal lobe revealed neu-ropathological findings consistent with Alzheimer's disease.
