Here's a link to an article, from Psych Central's archives, by our host Dr. John Grohol, Psy.D. on the subject of bipolar disorder. The article provides links to a number of additional articles on the subject. Also included is a link to a blog, here on PC, on the subject of getting older with bipolar:

I hope you find PC to be of benefit.
