The team asks local doctors to perform study in which newly diagnosed children with ADHD (n = 20) are matched with other children taking the current medication (n= 20) based on symptoms and physical attributes of the children. The research team will then test all the children after one year to determine the effectiveness of the treatments with a standardized symptom score-sheet (scores can range from 1-50).
