Musical therapy
I was reading a book today about some degenerative neurological illnesses. This has been an interest to me as my mother died from a side effect of a form of dementia. Once I found out what was wrong with her, I've been reading up a storm.
Anyway, a prominent researcher (don't have the book handy will find the page tomorrow) has found that the unknown part of the brain that appreciates music does not degenerate. People with these disorders may lose the ability to eat and even talk, but will still appreciate music.
I wonder if that might be why, especially in early recovery, people are so attracted to music of all forms. Look at the music posts here in Secular, the Cafe etc.
Anyway, just something to think about.
