Problem With Demonic Possesion Options

My problem is that i have a grandmother and since i have known her she always hears things that aren't there or at least that i can hear so a few years ago my mom told me that my grandma use to practice santeria and witchcraft without knowing what she was doing then she one day stop practicing and started going to a catholic church and since that day she began to hear things like people talking about her and stuff. When my mom was about 20 she took my grandma to christian church and there she ask the pastor to pray for my grandma and while they were doing it my grandma lost coinceness and the demon that was tormenting her said that he would not liver and that she belong to him and it didn't live.

Everything was ok until a about a year ago when she began to hear voices again but this time every day and not only that but she began to see thing to. Things like shadows and other things that aren't there.

Last night i went to sleep late around 5 am and this morning i heard people fighting and screaming and was my grandma fighting with my mother. When i ask her what why they were fighting again my mom told me that my grandma said the the voices told her that we had allowed some one to put a microphone and a speaker on her room and that that is why she hears things.

I wanted to know if there is something i could do to help her. Before she harms others or her self.

Ps: wold a demon get mad if you tell the person that is posses that whats inside of them is a demon. Because everything was fine until we began to tell her that what was tormenting her were demons.

Being that you said your G'ma has always heard things as long as you've known her, I would rule out Alzheimer's. As a person who works in the mental health field, I agree with your idea to have her seen by a psychiatrist. A psychologist could also do further testing to find out if she's experiencing a mental health disorder. It's alsways wise to rule out medical causes before you look at spiritual causes. Any spiritual remedy will not help a medical condition. I pray that you and your family find the appropriate remedy for her soon.
