Saints, demons, and faith - A review of the historical interaction between Christianity and epilepsy.

The view that epilepsy is caused by demonic possession prevailed throughout the Middle Ages and re-emerges in rare cases of misguided exorcisms even in modern Western societies. This review reflects on the biblical sources of the demonic understanding of seizures and the subsequent marginalization of people with epilepsy. While the development of science led to a decline in beliefs of supernatural causes of seizures, the link between Christianity and epileptology is sustained through recurrent considerations of epileptic phenomena among religious figures. The influence of epilepsy on the legacy of historical persons of Christianity should be regarded with caution because of limited clinical evidence in historical documents. However, it should be acknowledged that religious experiences, as well as general religiosity, can be important in modern-day epilepsy care as they are shown to have psychological, societal, and even clinical implications. Further studies should expand our knowledge on the contemporary importance of the Christian tradition for people with epilepsy.
