Memory deficits after bilateral anterior fornix infarction.
The authors report a patient who suddenly developed memory loss without any other focal neurologic deficits. Neuropsychological testing showed severe anterograde verbal and visual memory deficits that improved gradually over several months, but not to the point of the premorbid state. Brain MRI with diffusion-weighted imaging performed 3 days after onset revealed acute infarction involving the bilateral fornices and the right genu of the corpus callosum. The authors suggest that acute fornix infarction may cause anterograde memory deficits.
