ADHD is a neurobiological-based brain disorder, most often hereditary, affecting nearly one in twenty students. The ADHD brain functions differently because the area between the frontal lobe and rear lobe is having short-circuit problems and is not transmitting necessary information. The technical part of the disorder does not engage us as teachers as much as how the disorder manifests itself in the classroom. Generally, the ADHD student is busier than all of the other students put together. He or she may require 97% of a teacher's energy. He or she cannot stop moving or talking or both. His or her hands are not on his lap or the tabletop. They are on someone or something. He or she is not waiting for instructions or following directions. He or she is obstinate.
