Can I receive SSI for having ADHD?

Okay. I have heard from a couple different people that I could receive SSI (Social Security Income) for having ADHD. I was diagnosed with is in late February to early April of 2010. I started taking Vyvanse in April and continued that until the summer. Then I started taking Concerta until a month ago or more and now I am taking Adderal. And, I'm 14. Anyway, I was wondering If it is true that I can get SSI for having ADHD.
