Bipolar Disorder

Bipolar disorder, which used to be called manic depression, involves both periods of feeling low (depressed) and high (mania).

Most people experience a range of moods depending on what's happening in their lives. When good things happen, like getting a new job, going on a holiday or falling in love, it's natural to feel happy. On the other hand, when there are difficulties like losing a job or a loved one, having money or family problems, it can make a person feel down.

However, people with bipolar disorder experience extreme moods that can change regularly and may not relate to what is happening in their lives, although their mood swings may be triggered by certain events.
