About bipolar disorder

People with bipolar disorder have periods of extreme low mood (depression) and periods of extreme high mood and excitability (hypomania or mania).

The periods of low or high mood and the times with normal mood in between vary from person to person.

Bipolar disorder is not being a moody person, but is a serious illness, affecting sufferers' day-to-day life. It can make ordinary living very difficult.

When a teenager develops bipolar disorder it can seem quite different from bipolar disorder in an adult. In teenagers, it often starts with psychotic symptoms, such as severe social withdrawal, and unusual thinking and beliefs. The classic pattern of very high moods followed by very low moods might not show for several years.
