We have a 16 year old son who was diagnosed with ADHD many years
    ago 
[Fred A. Baughman Jr., MD: never proved to be an actual disease, meaning your son, with this the only dx., has never been proved to be abnormal. No doubt he and family have been led to believe he is brain-abnormal, diseased.]
.
  He has been on and off medication(aderol, ritlan) for approx. 5 years.
  
[Fred A. Baughman Jr., MD: these are amphetamines, amphetamine-like, addictive dangerous, having caused 186 (FDA-reported) deaths, 1990-2000.]

    We do not wish to give him the medication, but he has not been able to
    succeed in school without it 
[Fred A. Baughman Jr., MD: this is powerful belief in "disease" belief that he is not normal, cannot function without drugs. This must be overcome and meds should be stopped due to accumulative risks, but weaned with assistance of a physician ]
  We are unsure what course we need to take. Can
    you offer any advise on how we can help him succeed in school without
    medication? 
[Fred A. Baughman Jr., MD: I would try contract educators--Sylvan, Huntington, Score, Linda-Mood while never going bact to the belief your sone has a brain disease needing "treatment" Contact me direct should this become a legal matter. ]
