Клиническая ликантропия: психическое расстройство и иллюзия превращения в животное.

Clinical lycanthropy is a rare psychiatric syndrome that involves a delusion that the affected person can transform into, has transformed into, or is, a non human animal. Its name is associated with the mythical condition of lycanthropy, a supernatural affliction in which humans are said to physically shapeshift into wolves.

Clinical lycanthropy is a very rare condition and is largely considered to be an idiosyncratic expression of a psychotic or dissociative episode caused by another condition such as Dissociative Identity Disorder, schizophrenia, bipolar disorder or clinical depression. It has also been associated with drug intoxication and withdrawal, cerebrovascular disease, traumatic brain injury, dementia, delirium, and seizures. However, there are suggestions that certain neurological conditions and cultural influences may result in the expression of the human animal transformation theme that defines the condition.

One important factor may be differences or changes in parts of the brain known to be involved in representing body shape (e. g., see proprioception and body image). A neuroimaging study of two people diagnosed with clinical lycanthropy showed that these areas display unusual activation, suggesting that when people report their bodies are changing shape, they may be genuinely perceiving those feelings.

Because clinical lycanthropy is strongly associated with psychotic disorders, antipsychotic medication is often an effective treatment. It may also be treated with antidepressants or mood stabilizers, in cases in which it is a symptom of depression or bipolar disorder. Patients with clinical lycanthropy may also benefit from a cultural approach to treatment, as the syndrome is generally agreed to be culture bound.

Clinical lycanthropy is a type of delusional misidentification syndrome of the self, and it often overlaps with other delusional misidentification syndromes. For example, there is a case study of a psychiatric patient who had both clinical lycanthropy and Cotard delusion. In rare cases, individuals may believe that other people have transformed into animals. This has been termed "lycanthropic intermetamorphosis" and "lycanthropy spectrum". A 2009 study reported that, after the consumption of the drug MDMA (Ecstasy), a man displayed symptoms of paranoid psychosis by claiming that his relatives had changed into various animals such as a boar, a donkey and a horse.

Catherine Clark Kroeger has written that several parts of the Bible refer to King Nebuchadnezzar's behavior in the book of Daniel 4 as being a manifestation of clinical lycanthropy. Neurologist Andrew J. Larner has written that the fate of Odysseus's crew due to the magic of Circe may be one of the earliest examples of clinical lycanthropy. It is believed that the Armenian king Tiridates III also had this disorder. He was cured by Gregory the Illuminator. According to Persian tradition, the Buyid prince Majd al Dawla was experiencing an illusion that he was a cow. He was cured by Ibn Sina. Notions that lycanthropy was due to a medical condition go back to the seventh century, when the Alexandrian physician Paulus Aegineta attributed lycanthropy to melancholia or an "excess of black bile". During 1563, a Lutheran physician named Johann Weyer wrote that werewolves had an imbalance in their melancholic humour and exhibited the physical symptoms of paleness, "a dry tongue and a great thirst" as well as sunken, dim and dry eyes. Even King James VI and I in his 1597 treatise Daemonologie does not blame werewolf behaviour on delusions created by the Devil but "an excess of melancholy as the culprit which causes some men to believe that they are wolves and to 'counterfeit' the actions of these animals". The perception of an association between mental illness and animalistic behaviour can be traced throughout the history of folklore from many different countries.

On August 15, 2016, Martin County Florida Sheriff's Office deputies found a 19 year old male on top of a bloodied 59 year old man, gnawing on his face, eating pieces of flesh, and making growling sounds. Officers tased, repeatedly kicked, and ultimately required a police dog's assistance in subduing the 19 year old. Inside the garage of the home on Southeast Kokomo Lane, just north of the Palm Beach County line, deputies found a 53 year old woman, beaten, bloodied and unresponsive. Ultimately both the 59 year old man and 53 year old woman would die from their injuries. In the weeks ahead of this incident, the 19 year old told family members he believed he was either half man, half horse or half man, half dog. Clinical psychologist Dr. Phillip Resnick later assessed the 19 year old as having clinical lycanthropy. A 20 year old man was admitted to a mental hospital due to his increasingly agitated and erratic behaviors. During his initial evaluation, he was guarded and preoccupied. He had no previous psychiatric history. Over the next few days, he displayed increasingly psychotic, animal like behaviors. These behaviors included howling loudly, running abruptly, and walking on all fours (known as quadrobics). He appeared to be internally stimulated. When asked about these behaviors, he was initially evasive but eventually admitted that he believed he was a werewolf and would periodically transform into a wolf. He started believing this after having visions of "the Devil" years before and reported hearing random voices. The patient was started on ziprasidone and his symptoms gradually responded and his animal like behaviors eventually ceased altogether. A 25 year old man was sent for treatment during a period of excessive hand washing, irritable behavior, decreased sleep, and acting like a buffalo. The patient reported that he had engaged in sexual activity with his buffalo and believed that buffalo cells had entered his body and were transforming him into a buffalo. He began obsessively washing his hands and genitals in order to avoid the transition. He saw himself as having buffalo body parts and became preoccupied about his appearance. He then began to act as a buffalo by nodding his head, walking on all fours, and seeking out hay and grass to eat. He was ultimately diagnosed with obsessive compulsive disorder and body dysmorphic disorder with delusional beliefs. He was treated with fluoxetine and risperidone, and after 6 months of pharmacotherapy, his body dysmorphia and hand washing were both reduced.
