Bipolar disorder – known in the past as manic depression – is a condition that affects your moods, which can swing from one extreme to another.
If you have bipolar disorder, you will have periods or “episodes” of:
- depression – where you feel very low and lethargic
- mania – where you feel very high and overactive (less severe mania is known as hypomania)
The symptoms of bipolar disorder depend on which mood you are experiencing. Unlike simple mood swings, each extreme episode of bipolar disorder can last for several weeks or longer, and some people may not experience a “normal” mood very often.
