The onset of
bipolarBipolar disorder
Bipolar disorder disorder ranges from childhood (as early as age 5) to 50 years, or even older in rare cases, with a mean age of 30 years. I am not aware of any consistent data that suggest that bipolar disorder may be aggravated by birth control pills, menstrual cycles, over-the-counter medications, high sugar diet, caffeine, or nicotine.
