Which of the following is TRUE about manic-depressive psychosis?
Correct Answer: Mood disorders often have seasonal patterns
Description: Mood disorders often have seasonal patterns. Acute episodes of depression are common in spring and fall, whereas mania appears to cluster in the summer months. Suicide rates also show a peak in the spring and a (smaller) peak in the late fall. Higher rates of hypothyroidism, greater use of antidepressant medication, and changes in reproductive status and gonadal steroids may account for the greater prevalence of rapid-cycling bipolar disorder among women. Cyclothymic disorder consists of hypomania and less severe episodes of depression. Manic episodes typically begin suddenly, with a rapid escalation of symptoms over a few days, often, they are triggered by psychosocial stressors. Ref: Loosen P.T., Shelton R.C. (2008). Chapter 18.
