Klüver–Bucy syndrome is a syndrome resulting from bilateral lesions of the medial temporal lobe (including amygdaloid nucleus). Klüver–Bucy syndrome may present with compulsive eating, hypersexuality, insertion of inappropriate objects in the mouth (hyperorality), visual agnosia, and docility. Klüver–Bucy syndrome is more commonly found in rhesus monkeys, where the condition was first documented, than in humans. Pathology on the syndrome is still controversial with Norman Geschwind's theory and Muller theory offering different explanations for the condition. Treatment for Klüver–Bucy syndrome is minimal with no current cure. Symptoms The list of symptoms generally include the following: Docility, characterized by exhibiting diminished fear responses or reacting with unusually low aggression. This has also been termed "placidity" or "tameness". Dietary changes and hyperphagia, characterized by eating inappropriate objects (pica), or overeating, or both. Hyperorality, described by Ozawa et al. as "an oral tendency, or compulsion to examine objects by mouth". Hypersexuality, characterized by a heightened libido or a tendency to seek sexual stimulation from unusual or inappropriate objects. Visual agnosia, characterized by an inability to recognize familiar objects or people. While this cluster of syndromes is common to such sources as 1997's The Neuropsychiatry of Limbic and Subcortical Disorders, 2005's Functional Neuroanatomy: Text and Atlas and 1997's "Single-Photon Emission CT and MR Findings in Klüver-Bucy after Reye syndrome", an article in the American Journal of Neuroradiology, the three vary thereafter. Inconsistent criteria include: Hypermetamorphosis, characterized by Ozawa et al. as "an irresistible impulse to notice and react to everything within sight". This is included under the classification systems described by The Neuropsychiatry of Limbic and Subcortical Disorders and "Single-Photon Emission CT and MR Findings in Klüver-Bucy". Lack of emotional response, diminished emotional affect. This is a symptom under The Neuropsychiatry of Limbic and Subcortical Disorders and is included under "Single-Photon Emission CT and MR Findings in Klüver-Bucy" along with apathy under docility. Amnesia, characterised by an inability to recall memories. This only occurs when the damage extends bilaterally into the hippocampus. Pathology There are a few theories that attempt to explain the processes behind Klüver–Bucy syndrome and its symptoms. This topic still remains controversial as complete Klüver–Bucy syndrome is rare in humans especially compared to monkeys. Klüver–Bucy syndrome is thought to occur from damage to temporal sections of the limbic networks, which connects to other structures that regulate emotional behavior.Norman Geschwind's theory states that Klüver–Bucy syndrome is caused by disconnect syndrome (a condition of
