Demonic Possession
Demonic possession is the state of being physically and mentally possessed by Satan, a demon or evil spirits. This "diagnosis" is very rare and is generally made by religious officials when an individual shows symptoms such as mega-strength, antipathy to religious symbols and substances, etc. When diagnosed this condition is generally treated through the use of an "exorcist," a religious official who has been specifically trained to deal with this type of problem. Comparatively few cases have been well and truly documented and the truth of this condition is strongly debated between scientists and theologists.
