Dear A.,
I haven't had any actual experience with this disorder, but if I were you, I would go on the internet and search for information.
I remember studying about a technique for helping dislexic, (sorry about the spelling) people from Australia and another very good idea about teaching children to read using their own talents. So maybe they have something on the web about Sensory Processing Disorder. I have noticed that our minister is dislexic and has overcome it. I can tell because of being a teacher so long ago, and you never get over paying attention to people.
Could your doctor be talking about autism? That is a sensory problem too.
That is all that I can think of. Good Luck and never stop trying to get more information. Go to the AMA and the CDC websites also.
Sincerely, C. N.
