Man with Bipolar Disorder
Bipolar disorder, also known as manic depression, is characterized by shifts in a person's mood, energy, and capacity to function that range from euphoria to deep depression. The duration and intensity of these mood states vary widely. Fluctuating from one mood state to the next is called cycling. Bipolar disorder tends to run in families, and those families tend to have an increased incidence of depression. There is also a higher rate of suicide. Special consideration must be given to treatment, because certain medications used to treat depression may cause mood swings in these patients.
