Catherine Zeta-Jones has bipolar II disorder, a form that has more extended down periods, following a difficult time in her personal life. Zeta-Jones went through a period of mood swings following an intense period of stress when her husband, Michael Douglas, battled stage IV throat cancer. Adding to the stress was a fight with Douglas’ first wife over royalties from the actor’s movie, “Wall Street: Money Never Sleeps.” Stress is often a trigger for the disorder.
