Klüver–Bucy syndrome is a syndrome resulting from bilateral lesions of the anterior temporal lobe (including amygdaloid nucleus). Klüver–Bucy syndrome may present with hyperphagia, hypersexuality, hyperorality, visual agnosia, and docility. ==Symptoms== The list of symptoms differs somewhat by source. Generally included are the following: #Amnesia. Characterised by an inability to recall memories. Its nature is both anterograde and retrograde, meaning new memories cannot be formed and old memories cannot be recalled. The level of amnesia is considered to be profound. #Docility. Characterized by exhibiting diminished fear responses or reacting with unusually low aggression. This has also been termed "placidity" or "tameness".〔〔Ozawa, 540.〕〔 #Dietary changes and/or Hyperphagia. Characterized by eating inappropriate objects (pica) and/or overeating.〔〔Ozawa, 540.〕〔 #Hyperorality. This was described by Ozawa et al. as "an oral tendency, or compulsion to examine objects by mouth".〔〔〔 #Hypersexuality. Characterized by a heightened sex drive 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.〔〔 *Memory loss. This symptom is listed in ''The Neuropsychiatry of Limbic and Subcortical Disorders''.〔 It is also referenced by the National Institute of Neurological Disorders and Stroke.〔(【引用サイトリンク】 NINDS Klüver-Bucy Syndrome Information Page )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Klüver–Bucy syndrome」の詳細全文を読む スポンサード リンク
