Dr. Daniel Amen.... has books and a website explaining his Spect scans. I've seen him on PBS lectures, and he is really interesting.
He believes that head injuries really account for reduced brain functions and personality changes. His book Change your Brain, Change your LIfe is really interesting. I found it at our library.
