The book Ghost In My Brain arrived yesterday. The following quote is from the forward:
By the time high functioning individuals with post-traumatic head injury notice that their memories are not what they used to be, or that they have difficulty thinking through a problem they could once have easily solved, massive brain damage has occurred on a microscopic level. Because their symptoms are medically unverifiable and therefore untreatable, they are usually dismissed as the walking wounded, destined to suffer the pain, frustration, and humiliation of not knowing how much longer their condition will last or how much worse it will become.
