Voodoo death, a term coined by Walter Cannon in 1942 also known as psychogenic death or psychosomatic death, is the phenomenon of sudden death as brought about by a strong emotional shock, such as fear. The anomaly is recognized as "psychosomatic" in that death is caused by an emotional response—often fear—to some suggested outside force. Voodoo death is particularly noted in native societies, and concentration- or prisoner of war camps, but the condition is not specific to any particular culture.
