Rapid cycling is generally if a person as more than 4 true episodes , episodes are defined of at least 2 solid weeks of depression and separate 2 weeks of Hypo for BP2 or manic BP 1 ... this happens over a rolling period of 12 months. So not a calendar year.

Often times people think they rapid cycle , but often it’s just a case of having not found true stability and stayed there for a good amount of time. A person needs to have there mood something solid to compare it with.

Just how my Pdoc , T and myself feel about “ rapid cycling”
