Which is NOT characteristic of Klüver-Bucy syndrome?

Klüver-Bucy syndrome is a neurological condition typically resulting from bilateral damage to the anterior temporal lobes, particularly the amygdala. The syndrome is characterized by a set of behavioral aberrations, including significant changes in emotion and behavior.

Hypersexuality occurs because of the loss of normal social constraints and sexual inhibition, which is a hallmark of the condition. Visual agnosia, where individuals have difficulty recognizing familiar objects despite intact vision, is also a characteristic symptom due to damage in the temporal lobe areas associated with visual processing. Hyperorality, which involves compulsively examining objects by mouth and an increased tendency to eat inappropriate items, is observed as well. These behaviors stem from the disinhibition of normal controls provided by the temporal lobes, particularly affecting emotional responses and social behavior.

Aggressiveness, while it can occur in various neurobehavioral conditions, is not a defining feature of Klüver-Bucy syndrome. Patients typically display more docility and emotional blunting rather than increased aggression. Thus, the absence of aggressiveness in the presentation of Klüver-Bucy syndrome helps distinguish this condition from others that may feature more aggressive behaviors.
