Hypomania is a phase of bipolar disorder characterized by euphoria, increased energy, decreased need for sleep, and increased productivity. While these symptoms may seem desirable, hypomania often precedes full manic episodes involving disabling symptoms that can lead to hospitalization or job loss. Additionally, the "high" of hypomania does not last and will inevitably flip into a depressive state. Portrayals like Claire Danes' character on Homeland provide a realistic example of the disconnected thought processes and nonstop speech that occur during hypomanic episodes.
