The links on this page are sites that I have personally navigated and have no hesitation in recommending to patients as a source of medical information.  The other nice thing about sites here is that it saves me the trouble of creating web pages which have this information.

(1) Bipolar disorder
Incredibly informative site created and maintained by Dr. Phelps on bipolar disorder.  A must read for anyone looking for more information about this condition, or patients who have bipolar disorder.
