Abstract

Even a single brain infarct can cause dementia when it occurs in functionally critical areas of the brain. A 71- year-old female developed sudden cognitive impairment without any other focal neurologic deficits. A brain MRI revealed a bilateral anterior fornix infarction. Neuropsychological evaluation revealed verbal and visual memory deficits, visuospatial dysfunction, and frontal executive dysfunction. The cognitive impairment did not improve for 3 months and the patient showed impairments in daily activities. We report a patient who demonstrated strategic infarct dementia after a bilateral anterior fornix infarction. KeyWords:Vascular dementia, Fornix (brain), Infarction
