Bipolar disorder is an illness that is characterized by extreme mood shifts and changes in energy levels. It is sometimes referred to as manic-depressive disorder. People with bipolar disorder cycle through periods of depression and mania, which may alternate several times during a single episode. During the manic phase, a person may feel overly confident, energetic, and irritable. During the depressive phase, a person may experience feelings of sadness, hopelessness, fatigue, and a lack of interest in activities that they typically enjoy. Symptoms of bipolar disorder can vary from person to person and can interfere with daily functioning, making it challenging to work or maintain relationships. It is thought that bipolar disorder has biological and environmental components. While the exact causes remain unknown, certain factors may play a role in its development. Genetic factors have been identified as one potential cause, as individuals with a family history of the disorder are more likely to develop it. Stressful life events, such as a divorce or job loss, may also trigger an episode. Certain drugs, including stimulants, may also exacerbate symptoms. Treatment for bipolar disorder typically includes medication and psychotherapy. Antidepressant medications may be prescribed to help regulate moods, while antipsychotics may be used to control mania and other disruptive symptoms. Long-term treatment may be necessary for effective management of both the manic and depressive aspects of the disorder. Psychotherapy is also an important element of treatment. Cognitive-behavioral therapy (CBT) is used to help individuals gain insight into their disorder and learn skills to regulate their emotions, such as relaxation techniques and problem-solving strategies. Support groups can also be beneficial, as they can provide an outlet for people to talk about their experiences and learn from others who are living with the disorder. Bipolar disorder is a serious mental illness that requires proper diagnosis and treatment.
