There are times when you are ecstatic, and your joy knows no bounds. The next moment you are unreasonably irritable, angry, and frustrated. Your mood swings affect your behavior, thought process, sleep, energy levels, and power of judgment. The condition that causes extreme mood swings – episodes of extremely elevated mood (mania/ hypomania) or emotionally low (depression) is known as Bipolar disorder. There are different types of bipolar and related disorders. Bipolar I disorder is defined by manic episodes that last at least a week or by manic symptoms that are so severe that the person needs immediate hospital care. Depressive episodes, which typically last at least two weeks, can also occur. Episodes of depression with mixed features (having depressive symptoms and manic symptoms simultaneously) are also possible. Bipolar II disorder is defined by a pattern of depressive episodes and hypomanic episodes. It is different from the full-blown manic episodes typical of Bipolar I disorder. Cyclothymic disorder also Cyclothymia is defined by periods of hypomanic symptoms and periods of depressive symptoms lasting for at least two years (one year in children and adolescents). However, the symptoms do not meet the diagnostic requirements for hypomanic and depressive episodes. Other types are usually induced by certain drugs or alcohol or due to a medical condition, such as Cushing's disease, multiple sclerosis, or stroke.
