Man's Bipolar Mood Cycles Linked to the Moon | American Council on Science and Health
The author observed the behavior of a 51-year-old man with bipolar disorder. Patients with bipolar disorder experience manic-depressive cycles. The depressive cycles resemble those of patients suffering from severe depression, while during manic cycles, patients are hyperactive. Sleep patterns are abnormal, with patients sleeping too much during depressive episodes and not enough during manic episodes. In a sort of vicious cycle, disturbances in sleep pattern appear to be both a cause and effect of manic-depressive episodes.
