A disorder associated with episodes of mood swings ranging from depressive lows to manic highs. The exact cause of bipolar disorder isn’t known, but a combination of genetics, environment and altered brain structure and chemistry may play a role.
Manic episodes may include symptoms such as high energy, reduced need for sleep, and a loss of touch with reality. Depressive episodes may include symptoms such as low energy, low motivation, and a loss of interest in daily activities.
Mood episodes last days to months at a time and may also be associated with suicidal thoughts. Treatment is usually lifelong and often involves a combination of medications and psychotherapy.
