Definition for bipolar disorder

Bipolar disorder, once known as manic-depression, is a psychiatric diagnosis referring to a mental health condition defined by periods of extreme, often inappropriate, and sometimes unpredictable mood states.

Bipolar individuals generally experience mania, hypomania or mixed states alternating with clinical depression and euthymic or normal range of mood over varied periods of time. There are many variations of this disorder. A person with bipolar disorder generally tends to experience more extreme states of mood than other people. Moods can change quickly (many times a day) or last for months. Bipolar individuals tend to have very 'black and white' thinking, where everything in life is either a positive aspect or a negative. Mood patterns of this nature are associated with distress and disruption, and a relatively high risk of suicide. Bipolar disorder is also associated with a variety of cognitive deficits, in particular, difficulty in organizing and planning. The disorder may also skew the ability to judge others' emotion, and alter sense of awareness. less
