Is Demonic possession merely brain damage?
All things relating to demonic possession such as personality shifts, speaking in tongues, retard strength, animalistic behaviour, and believing they are no longer human.
Such things that seem supernatural could be explained as malformed or damaged parts of the brain acting out.

Many people find demons an easier metaphor to understand than the concept of a malfunctioning brain.

whoops, i meant to include  in my reply as well. 

anyway, nah man, even a simpleton can understand the concept of brain damage. there are elements of actual possession that simply cannot be accounted for within a materialistic/naturalistic/mechanistic worldview. at some point when you examine the phenomenon rigorously you will have to admit that actual spirits are the most likely explanation.

when The Exorcist's director made a documentary about exorcists a few years ago he interviewed a top american neurologist. the neurologist was shown a particularly unsettling video of a possessed woman. do you know what he said? he said that possession seemed a likely possibility in her case. a neurologist, mind you. a highly regarded neurologist. he said that. 

people have this idea that only dummies believe in spirits and it's very, very far from the truth. but ok i'm done rambling. cheers.
