Here are a few more. I'm working my way through a very long list. One might say that we haven't reached a definitive conclusion on the genetic links that correlate with ADHD, but not only is it being studied, but there have been many useful discoveries.

Amtram: wow thanks for the links.
Another interesting gene I learned about recently is the "clock" gene and it's role in circadian rhythm, personality traits, bipolar disorder and ADHD.

I recently found out I had the 'not so good' variant allele . Which would help explain why I've never really had a normal circadian rhythm.
