The Internet Mental Health web site is an excellent resource for information on Bipolar I disorder, which primarily effects young adults to adults (14-44 years-old). It is the 6th leading disability in the developed world. Left untreated a typical Bipolar I patient will experience from 8 to 10 episodes of mania and depression in a lifetime.

If left untreated Bipolar I patients have a 15% chance of commiting suicide. Mood-stabilizing medication is essential for a full social life and stable employment. Regardless of medication mild depressive symptoms may persist.
