Persistent Klüver-Bucy syndrome after bilateral temporal lobe infarction

Klüver-Bucy (KBS) syndrome is a rare and complicated neurobehavioral syndrome in humans resulting from damage of bilateral anterior temporal portion, especially the amygdala. It can be seen in association with a variety of etiologies. Stroke is a rarely reported. Here we present a 50-year-old right handed man who developed persistent KBS after cardioembolic stroke involving bilateral lateral temporal lobes. He exhibited all clinical features of KBS including visual agnosia, hypersexuality, placidity, hyperorality and hypermetamorphosis. The anatomical basis of pathophysiolgy, clinical course and possible treatment are discussed.
