Hello, I come from a family of 6 children, one, a brother has bipolar. I do not have bipolar, but suffer with depression, and have most of my life and take meds for. I have 3 children, my youngest daughter has bipolar. My sons are both married and have 2 children each. One son has a son and a daughter, and his wifes mother has bipolar.
My question is: what are the odds that one of my sons children will develop bipolar? also is there a prenatal test that could tell this information?
