Bipolar Disorder is disorder identified with episodes of mood swings ranging from depressive lows to manic highs.
The exact cause of bipolar disorder is still unknown, but a combination of genetics, environment and altered brain structure and chemistry may play significant a role.
Manic episodes may include symptoms related to high energy, reduced need for sleep and loss of touch with reality.
