I don't know if visual perception therapy will help with ADHD or not. I do know that visual perception therapy works. My son(who is now 25 and a submariner in the Navy) was not "diagnosed" with ADHD. However, when he was in first grade, his teachers told me he "didn't want to learn to read"; that he started goofing around, etc., during reading time. However, he would sit in his room at night and cry, saying "I'm so stupid". A chiropractor friend suggested he might have a visual perception problem, and suggested a specialist in Washington, DC. My son's problem was pretty severe - the specialist told me "I'm not surprised this child is having trouble learning to read. I'm surprised this child can read at all." Basically, his left eye just wasn't seeing letters, and sometimes whole words, so nothing was making sense. When he couldn't handle the frustration, he would start talking or goofing around. It took several blocks of therapy to help my son, but it is definitely money I would have spent time and time again. (If the doctor you are seeing is far away, ask if he can set you up with a home therapy program. After 2 blocks of therapy, we had to move to an area where there was no one who did this, and our doctor set up up with a program that I could do with my son at home.) Once my son's visual perception problems were addressed, his behavior issues in school disappeared, and he became an honor roll student. I don't know if this might happen with your son, but wouldn't it be wonderful if it did!
There are many natural supplements that can help children with ADHD. There is a specialist (Dr. Mary Ann Block) in this field who believes that a very high percentage of ADHD cases can be reversed with changes in diet. She became a doctor because of problems with her own child and she worked with children who no one else could help. She wrote a book called "No More Ritalin" and I believe it's a must read for parents of a child diagnosed with ADHD. It's a real eye-opener. You can purchase it from Amazon for less than $10. God bless you in your journey to help your son.
