Bipolar disorder, formerly called manic depression, is a mental health condition that causes extreme mood swings. These include emotional highs, also known as mania or hypomania, and lows, also known as depression. Hypomania is less extreme than mania.
When you become depressed, you may feel sad or hopeless and lose interest or pleasure in most activities. When your mood shifts to mania or hypomania, you may feel very excited and happy (euphoric), full of energy or unusually irritable. These mood swings can affect sleep, energy, activity, judgment, behavior and the ability to think clearly.
Episodes of mood swings from depression to mania may occur rarely or multiple times a year. Each bout usually lasts several days. Between episodes, some people have long periods of emotional stability. Others may frequently have mood swings from depression to mania or both depression and mania at the same time.
Although bipolar disorder is a lifelong condition, you can manage your mood swings and other symptoms by following a treatment plan. In most cases, healthcare professionals use medicines and talk therapy, also known as psychotherapy, to treat bipolar disorder.
