Watched it last night. It can be hard to watch at times because it does deal with an illness associated (generally) with aged people. Somewhat puts the question/fear in you that if you make it that long, will I be affected by Alzheimer or Dementia. Dr. Oz feels there will be cures in the next decade. Hope he is right. It was enlightening to see how well the patients came to life listening to their music.
 
The documentary though doesn't show patients that did not respond. That is my biggest question from the movie. Do some patient not like music? Perhaps they need some other stimulus? The current simple to control methods of medication may keep the patients alive and under control, but at what cost to quality of life. Alternative treatments such a musical therapy should be welcomed. I hope this music remedy can be further promoted, and have many more successes.
