Apologies for the English reply - my Afrikaans is not good enough to answer you query adequately. There is large debate around diagnosing ADHD in children as young as your son. It is important to remember that children at four years of age are very active and if he is a little immature he will have difficulties concentrating which may improve as his maturity does. There are also environmental factors which could cause ADHD-like symptoms including allergies and an abnormally functioning thyroid. If he does have ADHD, there are treatment routes other than medication including change in diet, occupational therapy or neurofeedback. Regarding your question of how long Concerta stays in your system: it ranges from 6-12 hours depending on the child's metabolism. There are other medications available which remain in the system for longer; your paediatrician will be in the best position to determine which, if any, medication would be most suitable.
