Kluver-Bucy syndrome occurs from bilateral amygdala lesions. Patients with this syndrome may present with hyperphagia, hyperorality, hypersexuality and disinhibited behavior. Other symptoms which may or may not be present include amnesia, docility, and visual agnosia. Development of all of these symptoms is extremely rare, and the presence of three or more is required for diagnosis.
