Bipolar disorder
From Conservapedia
Bipolar disorder was previously diagnosed as ‘manic depression’. As the older name suggests, someone with bipolar disorder will have severe mood swings. These usually last several weeks or months and are far beyond the experiences of the general population. The symptoms can be described as follows:
Low: ''Depressive' feelings of intense depression and despair.
High: 'Manic' feelings of extreme happiness and despair.
Mixed: Depressed mood with the restlessness and overactivity of a manic episode.
About 1 in every 100 adults has bipolar disorder at some point in their life. It usually starts during or after the teenage years and it is unusual for it to start after the age of 40. Men and women are affected equally.

Bipolar I
To meet the diagnostic criteria for Bipolar I, the individual must have experienced at least one high, or manic episode, that has lasted for longer than one week. Some people with Bipolar I will have only manic episodes, although most will also have periods of depression. When untreated, manic episodes can generally last 3 to 6 months, with untreated depressive episodes lasting 6 to 12 months.
Bipolar II
To meet the diagnostic criteria for Bipolar II, the individual must have experienced one episode of severe depression, but only mild manic episodes (hypomania).
Rapid Cycling
To meet the diagnostic criteria for Rapid Cycling, the individual must have experienced more than four mood swings in a 12 month period. This affects around 1 in 10 people with bipolar disorder, and can happen with both types I and II.
Cyclothymia
To meet the diagnostic criteria for Cyclothymia, the individual must have experienced mood swings that are not as severe as those in full bipolar disorder. The length of the mood swing can be longer, however and can develop into full bipolar disorder.
Causes of Bipolar Disorder
Current spychiatric/mental health research suggests that Bipolar Disorder runs in families, as it seems to have more to do with genes than with upbringing. There may be a physical problem with the brain systems which control our moods - this is why bipolar disorder can often be controlled with medication. Episodes can sometimes be brought on by stressful experiences or physical illness.
