S18 is physically a man but due to his ADHD and learning diaabilititues his mental age is closer to 16 and it causes him a lot of stress and he begins to spin. It's a vicious cycle.
Some exciting new studies came out this year showing that phosphatidylserine (an amino acid supplement, very safe to take) works very well for ADD. In the study I saw, they used 100 mg twice a day for kids (although adults can take up to 200 mg twice a day, I read).
I put my boyfriend on it (he was treated for ADD as a child and definitely has some ADD traits still) at just 100 mg twice a day, and some gingko (because he has a history of mild brain injury) and he said the difference was very noticeable within a WEEK. I can see it too, he's much calmer and less scattered, better able to focus.
You can find the studies if you go to pubmed.com and put "phophatidylserine AND ADHD" into the search engine. Phosphatidylserine is available over the counter in the U.S., I ordered mine from Life Extension (lef.org).
