Bipolar disorder, also known as manic–depressive disorder, is a psychiatric diagnosis that describes a category of mood disorders defined by the presence of one or more episodes of abnormally elevated energy levels, cognition, and mood. These moods are clinically referred to as mania or, if milder, hypomania. Individuals who experience manic episodes also commonly experience depressive episodes or symptoms, or mixed episodes in which features of both mania and depression are present at the same time. These episodes are usually separated by periods of "normal" mood, but in some individuals, depression and mania may rapidly alternate. Extreme manic episodes can sometimes lead to psychotic symptoms such as delusions and hallucinations (Basco, 2005). Genetic factors contribute substantially to the likelihood of developing bipolar disorder, and environmental factors are also implicated. Bipolar disorder is often treated with mood stabilizer medications, and sometimes other psychiatric drugs. Psychotherapy also has a role, often when there has been some recovery of stability. In serious cases in which there is a risk of harm to oneself or others involuntary commitment may be used; these cases generally involve severe manic episodes with dangerous behavior or depressive episodes with suicidal ideation. There are widespread problems with social stigma, stereotypes and prejudice against individuals with a diagnosis of bipolar disorder. People with bipolar disorder exhibiting psychotic symptoms can sometimes be misdiagnosed as having schizophrenia, another serious mental illness (The National Institute of Mental Health, 2009).
The signs and symptoms of this illness are varying between individuals. Bipolar disorder is a condition in which people experience abnormally elevated (manic or hypo manic) and abnormally depressed states for periods of time in a way that interferes with functioning. Not everyone 's symptoms are the same, and there is no blood
