Apotemnophilia is a disorder characterized by the intense and long-standing desire for amputation of a specific limb. In recent years the word apotemnophilia has come to be seen to carry pejorative overtones, meaning as it does "a love of amputation" and implying that the condition is a sexual paraphilia. In an attempt to move towards a more neutral term for desiring an amputation McGeoch, Brang and Ramachandran proposed that the desire for an amputation be renamed "xenomelia", which derives from the Greek to mean foreign limb. Another term for the condition is body integrity identity disorder (BIID), but this has come to apply to not only those who desire an amputation but also those who want a range of disabilities including deafness, blindness and a spinal cord injury.

Apotemnophilia (xenomelia) has features in common with somatoparaphrenia. Some apotemnophiles seek surgeons to perform an amputation or purposefully injure a limb in order to force emergency medical amputation. (A separate definition of apotemnophilia is erotic interest in being or looking like an amputee. This separate definition should not be confused with acrotomophilia, which is the erotic interest in people who are amputees.

Apotemnophilia (xenomelia) was first described in a 1977 article by psychologists Gregg Furth and John Money: "Apotemnophilia: two cases of self-demand amputation as paraphilia." Until recently, the primary explanation for Apotemnophilia was psychological/psychiatric, however recent research suggests that here may be a neurological etiology for this disorder.

Neurological Etiology

In 2008, V.S. Ramachandran, David Brang and Paul D. McGeoch conducted research that suggested Apotmenophilia/Xenomilia is a neurological disorder caused by an incomplete body image map in the right parietal lobe.

The study carried out David Brang, Paul McGeoch and V.S. Ramachandran in 2008 was on two subjects. In 2011 Paul McGeoch et al. published the results of an experiment in which they were able to obtain MEG images of the parietal lobes for four research subjects, all of whom desired amputation. McGeoch and his co-researchers concluded that the images suggest "that inadequate activation of the right superior parietal lobe (SPL) leads to the unnatural situation in which the sufferers can feel the limb in question being touched without it actually incorporating into their body image, with a resulting desire for amputation". The authors noted that the right parietal lobe has long been associated with formation of the body image, and that damage to this region can cause a variety of body image disorders, such as somatoparaphrenia in which sufferers deny ownership of a limb. McGeoch et al proposed that unlike somatoparaphrenia, which can be viewed as an acquired disorder of body image, xenomelia should be seen as a developmental right parietal lobe disorder. This reported abnormality in the function of the right parietal lobe was subsequently supported by an 2013 anatomical study by Peter Brugger's group, which found a reduced cortical thickness of this part of the brain in people who desired an amputation when compared to controls.

In 2011 a group of researchers at the University of Southern California (Brain and Creativity Institute) proposed an alternative neurological hypothesis. These researchers proposed that "individuals with BIID may have a discrepancy between the commands from the motor cortex to the parietal lobe and from the sensory feedback to the same regions in the parietal lobe". This theory was based on the discovery that individuals who desire amputation sometimes experience phantom limbs after amputation. There is also recent research (2017) which suggests that structural hyperconnectivity within the sensormotor system also plays a significant role in xenomelia.

Classifications: Body Integrity Disorder

Patients diagnosed with apotemnophilia are sometimes classified as being patients who experience body integrity identity disorder (BIID). Apotemnophilia may be classified under BIID because patients feel discontented with their bodies and want to remove an otherwise healthy limb. It should be noted that in a 2014 review of the psychiatric and neurological literature, Anna Sedda and Gabriella Bottini stated that there is no consensus as to the best way to classify the desire for amputation:

"In summary, psychological/psychiatric explanations for the desire to amputate a healthy limb include two main hypotheses: a sexual compulsion, belonging to the paraphilic core, and an identity disturbance, paralleling gender identity disorder. At present, no new psychological/psychiatric explanations have been proposed; neither has this condition been included in the DSM-5 classifications."

Signs and symptoms

Depression

Apotemnophiles will become prone to extreme levels of depression caused by isolation, confusion and the inability to determine what they're supposed to be like physically and emotionally. Patients with apotemnophilia will feel that they are apart from the norm and will isolate themselves from socializing.

Intentional injuries

Injuries are caused by desperate attempts to get the unwanted limbs to be amputated. People with apotemnophilia have an ideal image of their bodies as an amputee with missing limbs. Originally developed at a young age, apotemnophiles will go through drastic measures to ensure that their ideal image of being an amputee is fulfilled. Mentioned below, apotemnophiles will purposely induce infections onto limbs or even harm themselves by going as far as partially sawing off limbs so medical professionals do not have a choice other than to remove the limb.

Sexual motivation

Apotemnophilia has frequently been connected to sexual desires. Apotemnophilia has been connected to sexual desire for a number of years, but it is important not to confuse apotemnophilia with acrotomophilia. One excerpt from a case study from the American Journal of Psychotherapy entitled A case of apotemnophilia: a handicap as sexual preference by Dr. Walter Everaerd, PhD. from Utrecht, The Netherlands interviews an apotemnophile who describes his development of sexual preference:

"He became attracted to amputation in his 10th year. An amputated boy is according to him happier than he himself... When he was about 11 year old, he thought that he would be happier with an amputated leg. He therefore tried to infect sores on his leg. No infections developed at the time. After that he did not make any more attempts. He feels that he would not be able to bear the pain resulting from it... In addition he has photos and drawings of amputated boys and men, war victims, at his disposal. He fantasizes a lot about these photos. The image of amputation takes on erotic importance. When masturbating, amputated boys and men play at the role of partner in his fantasies. He is often occupied with self-amputation or the amputation of possible partners. He fantasizes for example, that a group of young boys who were playing together erected a guillotine. They chopped off each others legs. He does not find his desire for amputated partners and his fantasies about amputation sadistic. He often reacts astonished when I ask him that. It is not the amputation itself that is important but rather the result of it. In the development of this preference alloapotemnophilia and autoapotemnophilia were established. Now amputation of his own leg has no longer a sexual meaning. He says now that he only could feel complete once his leg has been amputated. Wanting to be amputated plays an important role in his sense of identity." Sexual desires from a life experience at a young age can be connected to one of the causes of apotemnophilia.

Treatment

Apotemnophiles are usually normal in terms of psychology and have been proven to be emotionally healthy. However, due to its connections to being neurological, treatments are available to apotemnophiles. The major problem in providing treatment is that most apotemnophiles do not seek professional treatment for their condition. They are more likely to be found in the act of self amputation before actively seeking medical attention themselves. As mentioned in the article "I am in Depression", "One of the most prominent problems in the treatment of this disorder is that most apotemnophiles do not seek professional treatment for the condition, but rather receive it only when they have been caught in the act, referred by a surgeon they approached for getting an amputation or on the request of their sexual partner. Thus, their motivations for change may often stem from a desire to do it for someone else rather than from a genuine desire to change".

Cognitive and behavioral elements

Treatments for apotemnophiles have been studied; however, the two main forms of treatment seem to be a combination of cognitive and behavior elements that have been scientifically modified to change patterns of behavior and fetishes. These combinational therapy have significantly shown that there are reduced rates of recidivism than seen in untreated individuals.

Aversion therapy

Along with a combinational treatment of cognitive and behavioral focuses, another element that has been studied is something known as aversion therapy. The therapy provides aversive conditioning to deviant sexual fantasies. Therapies are provided by medical attention and have shown to reduce the effects of apotemnophiles. Along with therapy, apotemnophiles will be exposed to treatment that focuses on cognitive behavioral programs that include training in social skills that may help maintain the deviant sexual arousal and behavioral patterns.

Ethics

Surgeons are placed in a difficult situation when apotemnophiles confront them about their situation. A surgeon or a medical professional will have to make the decision between amputating a perfectly normal limb or allowing his or her patients to remain unhappy. Whether the medical professional performs this surgery has not been defined as "allowed" or "disallowed". Although many professionals will agree that a patient's happiness is primarily important, amputating a limb may be out of the question because there is nothing medically wrong with the limb itself.

Research directions

Apotemnophilia has been studied for a number of years to determine whether this disorder is actually neurological or psychological. However, in-depth research related to apotemnophilia and its correlation to the mind and body are still not clear. Recent research has shown small breakthroughs such that apotemnophiles are three times more likely to want removal of a left limb than right, in accordance with damage to the right parietal lobe, and also in concordance with sufferers of somatoparaphrenia; in addition, skin conductance response is significantly different above and below the line of desired amputation, and the line of desired amputation remains stable over time, with the desire often beginning in early childhood. Among a convenience sample of 52 apotemnophiles recruited from internet groups, the great majority wanted a single leg removed, cut above the knee. There are parallels between apotemnophilia as a motivation for body integrity identity disorder and autogynephilia as a motivation for some cases of male-to-female gender dysphoria.

A 2014 review concluded that

"In conclusion, the 37 years of study of this desire to be disabled...appears challenging to understand, even using state-of-the-art technologies. Much more effort is needed to find a solution and, finally, a treatment for the distress these individuals experience. This still-obscure condition needs a multidisciplinary approach to go beyond the “simple” clinical/experimental frame, and requires a much more complex model that also includes social and ethical aspects."
