      In response to the above question - yes, the age of onset of bipolar disorder is very related to it's prognosis. Generally pediatric bipolar has a worse prognosis than bipolar disorder that begins at a later date. There is also a big difference between Bipolar I and Bipolar II disorder and whether the episodes have a long or short time between them. Bipolar is a very complex disorder, and medication generally plays a really important role in managing this disorder. I hope this is helpful.

      I wish to know if the age of onset of bipolar disorder affects its prognosis. I mean if this disorder manifests at an earlier age is it more serious for the later years. One of my near and dear one is affected by this disorder.

      This is a great idea for a hub. People should be aware of the things that people face everyday and can't help before they make assumptions and even act on them.
