Lothlorian, I sure don't know the answer, but I will follow this thread with great interest as I'm in a similar situation.
You mention bipolar in your family tree. Heredity was a huge factor when we talked with the psychiatrist about my son. I swear, it seemed he was ready to diagnose my son as having bipolar based on family history alone. (Obviously I think he was overzealous, especially since he admitted he didn't know much about seizures.) I guess it's just me, but I was under the impression that pretty much everyone had a mood disorder or history of addiction in their family tree. We have it in spades!
I did talk to difficult child's neurologist about behavior and partial complex seizures. He told me there's no known cause and effect between seizures and behavioral issues, but that there is a higher incidence of behavioral issues in kids with partial complex seizures. I'm not sure if I understood that correctly, and we're pursuing a new neurologist, so I'll ask the question again. But, when my son was unmedicated for his seizures I could absolutely tell you when he was going to have a "seizure day" based on his behavior. And it was as erratic and unpredictable as - I think - bipolar behaviors must be.
Regarding separating out ADHD and Bipolar, just reading the intersection of symptoms makes my head spin. I hope you have a good team of professionals to help you figure it out!
So, sorry that I have nothing useful to add, but as I said, I'm very interested in what you find out! Good luck.
