Although Klüver-Bucy Syndrome is relatively rare, it’s one of the most notorious neurological causes of a complete breakdown in one’s ability to control sexual urges. (…) Dramatic case studies illustrating the devastating effects of Klüver-Bucy Syndrome abound in the clinical literature, and they raise intriguing philosophical questions for us to consider. That some patients so stricken are overcome with excessive carnal urges and are not simply using the disorder as a convenient excuse to become freely promiscuous, lewd, and lascivious is perhaps best demonstrated by a 1998 Clinical Neurology and Neurosurgerystudy by Indian neurologist Sunil Pradhan and his colleagues. In this report, a group of boys between the ages of 2.5 and 6 began to exhibit hypersexualized behaviors after partially recovering from comas induced by herpes encephalitis. One to three months after emerging from the comatose state, „all seven children,“ note the authors, „demonstrated abnormal sexual behavior in the form of rhythmic hip movements (two patients), rubbing genitals over the bed (two patients) and excessive manipulation of genitals (all seven patients).“ Were these children just helpless, hapless puppets of their ancient, pleasure-driven brains? The authors believe so. „As all patients [at the time of study], except one, were 4 years of age, with no possibility of environmental learning of sex, these movements most probably represented phylogenetically primitive reflex activities.“ (…)
In a 2005 letter to the editor of European Psychiatry, two physicians describe the case of a 14-year-old schoolgirl („Ms. A“), who, prior to developing Klüver-Bucy Syndrome after being in an encephalitis-caused coma, „was an intelligent and social girl with a good academic record.“ This quiet, well-behaved teenager became somewhat challenging, to say the least, after recovering from her illness. You think you’re raising a difficult teen? Consider what these parents were dealing with:
[T]he patient started … disrobing in front of others, manipulating her genitals, and making sexual advances toward her father. She would lick any object lying on the ground and whenever she got an opportunity, she would rush to the toilet and try to put urine and feces into her mouth (urophagia and coprophagia, respectively).
In another case, an epileptic woman underwent an unsuccessful left temporal lobectomy to help stop debilitating seizures. Klüver-Bucy symptoms, including hypersexuality, emerged following the surgery. She began masturbating in public and aggressively soliciting her family members and neighbors for sex. After having another seizure, she was brought to the emergency room, where, after a half hour in the waiting area, she began performing fellatio on an elderly cardiac patient. (This may or may not be one of the few examples where one person’s syndrome is another’s lucky day; it’s also unclear if this was a display of hypersexuality or hyperorality, but it’s inevitable, perhaps, that the twain should occasionally meet.)
Other temporal-lobe epileptics have also exhibited hypersexuality in the „postictal“ state, which is the period of recovery time following a seizure. In a recent issue of Epilepsy and Behavior, New York University neurologist Vanessa Arnedo and her colleagues present the case of a 39-year-old man who began having semi-frequent seizures during the middle of the night. After nocturnal convulsions, he’d sleep for another 10 minutes, wake up, and then rape his wife. (In the authors‘ more delicate wording, he was described as „becoming sexually aggressive toward his wife by forcing intercourse.“) Importantly, however, „the tremendous remorse and abhorrence for what he had done when he learned of his actions led him to pursue possible surgery mainly to eliminate this postictal behavior.“
Dies zeigt meiner Meinung nach, wie deutlich unsere Biologie in uns wirkt. Wir sind nicht frei uns zu verhalten, wie wir wollen, sondern unterliegen bestimmten Motivationen und Wünschen, die wir zwar ausgestalten können und auch mißachten können, es erscheint uns aber logisch, ihnen bis zu einem gewissen Grad nachzugehen. Fällt ein Teil aus, dass eine gewisse Hemmung bewirkt, dann brechen sich die Triebe nach wie vor eine Bahn.
