ADHD is neurotransmitters on overdrive. Consider neurotransmitters as vehicles on a highway. The average speed is 45-55 MPH for non-ADHD. Those with ADHD are 200-300 MPH or higher. Proper discipline and training can alleviate symptoms and need for medication. Studies have shown that physical activities, requiring discipline alleviate symptoms of both ADHD and ASD/HFA by engaging motor functions, which are affected by both conditions.
