Clinical Lycanthropy - Symptoms

Symptoms

Affected individuals report a delusional belief that they are in the process of transforming into an animal or have already transformed into an animal. It has been linked with the altered states of mind that accompany psychosis (the reality-bending mental state that typically involves delusions and hallucinations) with the transformation only seeming to happen in the mind and behavior of the affected person.

A study on lycanthropy from the McLean Hospital reported on a series of cases and proposed some diagnostic criteria by which lycanthropy could be recognised:

• A patient reports in a moment of lucidity or looking back that he sometimes feels as an animal or has felt like one.
• A patient behaves in a manner that resembles animal behavior, for example crying, grumbling, or creeping.

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 go on to note that, although the condition seems to be an expression of psychosis, there is no specific diagnosis of mental or neurological illness associated with its behavioral consequences.

It also seems that lycanthropy is not specific to an experience of human-to-wolf transformation; a wide variety of creatures have been reported as part of the shapeshifting experience. A review of the medical literature from early 2004 lists over thirty published cases of lycanthropy, only the minority of which have wolf or dog themes. Canines are certainly not uncommon, although the experience of being transformed into a hyena, cat, horse, bird or tiger has been reported on more than one occasion. Transformation into frogs, and even bees, has been reported in some instances. A 1989 case study described how one individual reported a serial transformation, experiencing a change from human, to dog, to horse, and then finally cat, before returning to the reality of human existence after treatment. There are also reports of people who experienced transformation into an animal only listed as "unspecified".
