    Adult info particularly helpful, that symptom evaluation is being fine-tuned, and that they are looking at long-term (in)effectiveness of meds. Adult ADHD/inattentive here, VERY small dose of dextromethamphetamine extremely helpful (far superior to Adderall for me and about 1/4 the cost), but as time goes by, attention is waning.

For example, the prevalence of ADHD in both Finland and the US would have to be the same so you would have a controlled variable to study symptoms. Shame on this researcher for violating one of the most important rules of research.

  3. can children or adults live with adhd for there wholle life?
