lycanthropy, a
supernatural affliction in which humans are said to physically

Affected individuals believe that they are in the process of transforming into an animal or have already transformed into an animal. It has been associated with the altered states of mind that accompany
psychosis

A study on clinical lycanthropy from the
McLean Hospital reported on a series of cases and proposed some diagnostic criteria by which clinical lycanthropy could be recognised:
* A patient reports in a moment of lucidity or reminiscence that they sometimes feel as an animal or have felt like one.
* A patient behaves in a manner that resembles animal behavior, for example howling, growling, or crawling.
According to these criteria, either a delusional belief in current or past transformation or behavior that suggests a person thinks of themselves as transformed is considered evidence of clinical lycanthropy. The authors note that, although the condition seems to be an expression of psychosis, there is no specific diagnosis of
mental or
neurological illness

It also seems that clinical lycanthropy is not specific to an experience of human-to-wolf transformation; a wide variety of creatures have been reported as part of the shape-shifting experience. A review

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

'' 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.
Case examples
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 crawling on all fours. 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
