Bipolar disorder, previously known as manic depression, is a mental disorder that causes periods of depression and periods of elevated mood.

Bipolar disorder is a mental disorder that affects a person's psychic condition characterized by extreme mood swings in the form of mania and depression, hence the medical term previously referred to as manic depressive

The elevated mood is significant and is known as mania or hypomania, depending on its severity, or whether symptoms of psychosis are present. During mania, an individual behaves or feels abnormally energetic, happy, or irritable. Individuals often make poorly thought out decisions with little regard to the consequences. The need for sleep is usually reduced during manic phases. During periods of depression, there may be crying, a negative outlook on life, and poor eye contact with others. The risk of suicide among those with the illness is high at greater than 6 percent over 20 years, while self-harm occurs in 30–40 percent. Other mental health issues such as anxiety disorders and substance use disorder are commonly associated.
