Recently, the NIMH (National Institute of Mental Health) distributed a press release entitled “Largest Study of Its Kind Implicates Gene Abnormalities in Bipolar Disorder.” According to the press release, this “largest genetic analysis of its kind to date for bipolar disorder has implicated machinery involved in the balance of sodium and calcium in brain cells.” As the press release points out, no single gene has been identified as the “bipolar gene.” Researchers generally agree that multiple genes contribute to make an individual more susceptible to the eventual onset of bipolar disorder.

Hi, my fiance is a not identicall twin, he think that his sister might have a bipolar disorder because his father and his family were bipolar. My concern is about our children. What’s the chance (percentage) that our children (in case we decide to have) develop this illness?
Hi, GL–
Check out our two-part series on “Bipolar Disorder & Heredity – The Genetic Link,” which provides the information you need to gauge the chance that any children you have might develop this illness.
