Visual Form of Alzheimer's Disease and Its Response to Anticholinesterase Therapy

Abstract

In a 60-year-old woman with the visual variant of Alzheimer's disease, single photon emission computed tomography abnormalities were most marked in the parieto-occipital regions of the brain. After treatment with donepezil, improvement is noted on neuropsychological testing and on brain SPECT, including increased perfusion (metabolism) in the occipital lobes.
