Circadian rhythms regulate changes in mental and physical characteristics that occur during a day. The word circadian, meaning "around a day," comes from the Latin words "circa" (around) and "diem" (a day).
Your body's biological clock controls most circadian rhythms. This clock is in a region of the brain called the hypothalamus.
Many studies have found significant disruptions in circadian rhythms in people with bipolar disorder. These rhythms affect sleep/wake activity, body temperature, and hormonal cycles. Changes to the sleep/wake cycle can precipitate manic and depressive episodes while stabilization of these rhythms is therapeutic. Register now to hear Dr. McClung share her research.
