I can only speak from my experiences. I had terrible visual and auditory processing. It's gotten much better, especially in this last month from vision therapy and syntonics (syntonic phototherapy). I see a behavorial optometrist trained in neuro-optometric rehab. About two months ago I was reading 15 minutes maximum at a time. I could probably do a 90-100 now. I've read lots of people have great success with vision therapy for both visual and auditory processing problems.

Here's the site. There may be a physician near you. Neuro-Optometric Rehabilitation Association

Good luck!
