autism

A photographic memory is not found in all diagnosed individuals but for those who do have it it is pretty amazing. I remember before my son was diagnosed he could recite the alphabet backwards just as easily as he did forward. Temple Grandin wrote a book called Thinking in Pictures in which she describes her brain like a computer and when somebody asks her a question she retrieves the information and can see it in her head. Lately they have been talking about people with these amazing memories in the media and they have determined a connection to obsessive compulsive disorder. As my son matured he has lost some of these mind capabilities not sure why but some people retain them through life.
