Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks.
A person with bipolar disorder can go from feeling very, very high (called mania) to feeling very, very low (depression). This can be disruptive and challenging.
