I would recommend you call Ditt at the Wellness Center that is located near 635 and Preston Rd. in North Dallas. His number is ###-###-####.
They will test for ADD_ADHD for FREE and then they do the brain mapping you were referring to. Once they identify the type and severity of the ADD, then the appropriate treatments are recommended. They DO NOT recommend meds! Their treatments are a SOLUTION.
I have seen first hand a 1st grade boy who had ADD so severely, that he could NOT function in school at all. After the brain scan and afew treatments, his teacher was AMAZED at the changes!
Hope this helps your son.
