A cycle is the period of time an individual takes to go through one episode of mania and one of depression (or hypomania and depression). As for how often these cycles occur, there is, unfortunately, no definitive answer. The frequency and duration of cycles are as varied as the individuals who have them. A study in 1992 found that 35% of people with bipolar disorder had only one cycle in a 5-year period, while 1% of the same group went through a complete cycle about every 3 months (Coryell et al). The phrase rapid cycling is tagged to the diagnosis of those who have four or more cycles in a 12-month period.
