I have a 13 year old cousin who was diagnosed at birth with CAH.  She's doing wonderfully, but has been starting to show signs of ADHD (hyperactivity disorder)

I've been told since she was very little that her medication (I can't think now of what it is) makes her hyperactive.  But she's also confused, distracted and has a hard time concentrating. 

My question, really, is if anyone out there has found a connection between CAH and ADHD, or if it really is the medication.

Thanks,

Judi
