Genetics or environment or both? What causes Bipolar Disorder?

Of course. I was just pointing out that environment-trauma can trigger facets of bipolar illness, but without the genetic component, not the full syndromes of bp or sz illness in my experience. I just find it fascinating that epigenetics is likely more critical than mendelian stuff for us. And trauma, bad stuff, can influence epigenetics. Wacky. Very complex.

I have: mgm w bp, dad w mdd, nephew w mdd, two 1st cousins w addiction, mom w addiction.

It's very complex and really quite fascinating when you think about it. All of the puzzle pieces have to be there, but they also have to come together in a very particular fashion in exactly the right time. It's like winning the lottery, but our prize sucks.
