Also known as manic-depressive illness, a bipolar disorder is a mental illness that is characterized by shifts in mood, thinking, behavior and energy. A person with bipolar disorder may have depression and mania, feeling overactive and very high or incredibly sad and lethargic. The symptoms are severe but also depend on the mood that a person experiences; fortunately, this condition can be treated.
People with a bipolar disorder may experience different symptoms in separate periods referred to as mood episodes. Episodes portray a change in behavior and mood. A very overexcited episode is referred to as a manic episode while a remarkably sad state is called a depressive episode. A mood episode that features both states is called a mixed state. A person that experiences less extreme symptoms usually faces a hypomania state, which is a less severe form of mania.
Many scientists agree that there is no one single cause for bipolar disorder, but many factors act together thus causing it or heightening the risk. Genetic factors and some brain activities are believed to contribute to the condition. This condition can occur to a person of any age. It can become worse in women during pregnancy so it is crucial to consult a doctor in advance.
