Klüver–Bucy syndrome results from bilateral lesions of the amygdala(almond-shaped groups of nuclei located deep within the medial temporal lobes of the brain forming a component of limbic system).
Characteristic symptoms are as follows:
Docility. Characterized by exhibiting diminished fear responses or reacting with unusually low aggression. This has also been termed “placidity” or “tameness”.
Dietary changes and/or Hyperphagia. Characterized by eating inappropriate objects (pica) and/or overeating.
Hyperorality – “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.
Inconsistent criteria include:
Hypermetamorphosis, “an irresistible impulse to notice and react to everything within sight”.
Lack of emotional response, diminished emotional affect.
