Parkinsons Help with Hallucinations

My dad has had Parkinsons for about 16 years and been pretty healthy in spite of this. A year or so ago he started to hallucinate quite badly.

Anyway the consultant pretty much told him that nothing could now be done for him a while back and for the past month or so he has had really strong hallucinations most of the time. I remember Richard Bandler talking about a case (different illness) where the psychiatrist got the guy to put a black line around the real images to differentiate from the imagined. I’ve concentrated with suggestions about telling the difference and being able to forget about the imagined images. Not had much of an effect and I wondered if a “grown up” NLPer/hypnotherapist may be able to help more?

I’m not expecting a cure per-se as the problem is caused by a chemical imbalance but I would hope that he may be able to at least learn to ignore the hallucinations more often and improve his situation?

I wondered if someone on the site who is skilled in this area would be interested in trying to make a difference here on personal sessions with my dad?

I don't ever believe in giving up, especially when a very respected clinician says that nothing more can be one with traditional medicine ..
