Addressing the single characteristic of attention/concentration through drug therapy is counterproductive and has long-term negative effects. Diagnosing a child or adult as ADD/ADHD based on this single characteristic is also erroneous. Other medical and behavioral problems also have attention/concentration or hyperactivity as a symptom, such as brain damage, nutritional and vitamin deficiencies, behavioral and emotional disorders, thyroid deficiency, environmental toxin exposure, etc. It is critical that a thorough differential diagnostic battery be administered to properly diagnose ADD/ADHD. There is no check sheet or inventory sufficient to diagnose ADD/ADHD properly.
