Bipolar disorder, formerly called manic depression, is classified as a psychological mood disorder. Those afflicted have an impaired ability to regulate their mood and are prone to episodes of both major depression and mania.
There are many types of depression. Many people experience some depression when they encounter significant disappointments or grief. Those with manic depression experience what is called major depression (a diagnostic contrast to the minor depression that everyone encounters at some point in life). Mental health professionals call the major depression of manic depressive patients bipolar depression.
Signs of major depression may include the presence of some of the following symptoms for a prolonged period of time, occurring every day or nearly every day:
In order to be diagnosed as bipolar, the DSM (the main diagnostic manual used by mental heath professionals) says that a person must have at least one manic episode not involving drug or alcohol abuse, medications or other medical disorder that may have caused the symptoms.
Being manic does not equate with just being in an especially great mood. Mania is an abnormally elevated mood that can include racing thoughts, fast or pressured speech, and irritability.
The following are possible symptoms of mania that are used in clinical diagnosis:
Each of the items on these lists, individually, are things that most people may commonly experience from time to time, even if they don’t have manic depression. To be diagnosed as bipolar, a patient must have several of these symptoms at the same time.
Some people with this disorder have substantial separate episodes of mania and depression throughout their lives. Some struggle more with bouts of depression. Some are more prone to manic episodes. And, although these moods may seem like diametric opposites, bipolar patients may also experience mania and depression at the same time. This is called a mixed episode.
