This is an ongoing problem in the paranormal field. We have so called demonoligists that call people with actual diagnosed medical conditions approached by these leaches telling them they have a demon in them and for a price they will remove it. This happens to people with Tourettes, Schizophrenia, Bi-polar, and a host of other known medical conditions. I have been trying to get from these demonoligists what symptoms a person must show to be possessed. I keep getting varying lists and most symptoms they do list are explainable with these diseases.
1. Talking in a strange language
Tourettes all the way
2. Super human strength
Adrenaline pump this is what happens in an accident when a person lifts a car off someone.
3. Hearing strange voices in their heads
Schizophrenia
4. Loss of reality
Schizophrenia
5. Unusually high sex drive
Schizophrenia
These are a few claims with the medical answers. So once again if you think you are experiencing demonic activity or worse yet are told your symptoms are demonic by a psychic or paranormal investigator consider getting a medical or mental examination first.
Don't get taken by a demonologists that says he can cure you for thousands of dollars.
