Hi Amy and welcome from a fellow NYer. First off, we aren't doctors here so we can't diagnose, but we can relate our experiences so that you may find the right path for your family. Here's a link that discusses some similarities and differences between ADHD and Bipolar:

You may also want to take a look through the Chandler Papers, located in our FAQ forum.
I won't speak to medication, since I only have very limited, second hand experience with medication for bipolar. Others will be along shortly offering their opinions.
