In 1661, The Jesuit Relations reported:

Although in many recorded cases of Wendigo psychosis the individual has been killed to prevent cannibalism from resulting, some Cree folklore recommends treatment by ingestion of fatty animal meats or drinking animal grease; those treated may sometimes vomit ice as part of the curing process.One of the more famous cases of Wendigo psychosis reported involved a Plains Cree trapper from Alberta, named Swift Runner. During the winter of 1878, Swift Runner and his family were starving, and his eldest son died. Twenty-five miles away from emergency food supplies at a Hudsons Bay Company post, Swift Runner butchered and ate his wife and five remaining children. Given that he resorted to cannibalism so near to food supplies, and that he killed and consumed the remains of all those present, it was revealed that Swift Runners was not a case of pure cannibalism as a last resort to avoid starvation, but rather of a man with Wendigo psychosis. He eventually confessed and was executed by authorities at Fort Saskatchewan.Another well-known case involving Wendigo psychosis was that of Jack Fiddler, an Oji-Cree chief and medicine man known for his powers at defeating wendigos. In some cases, this entailed killing people with Wendigo psychosis. As a result, in 1907, Fiddler and his brother Joseph were arrested by the Canadian authorities for homicide. Jack committed suicide, but Joseph was tried and sentenced to life in prison.
With respect to the role of drinking water, changing of water sources to deep well water has been reported to decrease the X-ray metaphyseal detection rate in different settings. In general, the effect of preventive measures however remains controversial, due to methodological problems (no randomised controlled trials), lack of documentation, or, as discussed above, inconsistency of results. Treatment
Treatment of KBD is palliative. Surgical corrections have been made with success by Chinese and Russian orthopedists. By the end of 1992, Médecins Sans Frontières—Belgium started a physical therapy programme aiming at alleviating the symptoms of KBD patients with advanced joint impairment and pain (mainly adults), in Nyemo county, Lhasa prefecture. Physical therapy had significant effects on joint mobility and joint pain in KBD patients. Later on (1994–1996), the programme has been extended to several other counties and prefectures in Tibet. Epidemiology
Kashin–Beck disease occurrence is limited to 13 provinces and two autonomous regions of China. It has also been reported in Siberia and North Korea, but incidence in these regions is reported to have decreased with socio-economic development. In China, KBD is estimated to affect some 2 million to 3 million people across China, and 30 million are living in endemic areas. Life expectancy in KBD regions has been reported to be significantly decreased in relation to selenium deficiency and Keshan disease (endemic juvenile dilative cardiomyopathia). The prevalence of KBD in Tibet varies strongly from valley to valley, and village to village.
