I'd like to suggest a book to you that was very interesting concerning the firing impulses of the brain, a guy I know who is much older than your boyfriend is reading and doing what the book suggests and he has a shrinking cerebellum disease this has helped him. The name of the book is 'Your bodies many cries for water' it has to do not only with water but certain nutrients that some people need for a correct sparking of the brain and nerve endings. It reads like a book, it doesn't have an index so if something sounds right make notes and mark the pages. I think it may be very helpful to you BF to check it out. You may even be able to find it at a library.
