Abstract
— The experience of using thyroid hormones in affective disorders is summarized. This includes: 1) Using thyroid hormones alone in depression; 2) their combined use with tricyclic antidepressants; 3) addition of thyroid hormones to non‐tricyclic antidepressants; 4) the use of thyroid stimulating hormone; and 5) thy‐rotropin releasing hormone in depression. Suggested mechanisms of action are discussed. A special attention is paid to the place of thyroid hormones in the treatment of rapid cycling affective disorder.
