My dad used to get reiki massages. This was something that he would never have thought of trying but it was recommended to him by his Macmillan nurse as he was having real problems sleeping and they thought it might help him.
Anyway, the first time they tried it on dad, he was asleep and snoring his head off after about 10 minutes. Then when he started going to day care, he would get a reiki massage every time and he said it was great for helping him relax and chill out a bit. He would also get feet massage at day care and he said that was great as well.
He also tried Lavender oil, a few drops of it on his pillow at night and relaxation CD's, again to help him relax a bit. I remember one time going round to see him and he was lying on the floor sleeping with one of the relaxation CD's playing, so I guess that helped him a bit!
Best wishes to you and your brother.
