Interpersonal and social rhythm therapy (ISRT) is a type of behavioral therapy designed specifically for bipolar disorder. As Wikipedia tells us, it’s:
used to treat the disruption in circadian rhythms that is related to bipolar disorder. ISRT provides a biopsychosocial model for bipolar disorder and recognizes that the illness cannot be fully treated with medication alone, although it is biologically based. It postulates that stressful events, disruptions in circadian rhythms and personal relationships, and conflicts arising out of difficulty in social adjustment often lead to relapses.
