My daughter was mis-diagnosed with ADHD with a very very devastating outcome from the medication. Same thing happened to another child in the family.
Look into allergies, intestinal malabsorption issues, food additives, and very very importantly and so overlooked in the United States -- SLEEP issues. Excellent sleep hygiene (being aware of both wake-up and sleep, light and dark) and nutrition is critical. Throw away the TV set and video games.
My daughter takes more pills that are supplements than pills that are pharmaceuticals. You might want to consult with a doctor (M.D.) that specializes in INTEGRATIVE medicine.
A lot of what she is on was just to get her BACK to almost the level of functioning she was at prior to the fiasco with the stimulant med she was given for the ADHD which apparently she didn't really have.
