Great article once again Doc! It's an interesting subject alright.

Exorcism the casting out of entities has been a human phenomenon since prehistoric times when medical knowledge was in its infancy.

In olden times spores (ergot poisoning) on tainted flour could cause convulsions and hallucinations in people. That was then perceived to be the work of the devil.

Then there's the power of belief, the main cases of possession come from religious families who believe such things are possible. You don't ever hear of cases of atheists needing exorcisms.

Fascinating case though, not quite sure what to make of it.
