Premenstrual mood changes. Characteristic patterns in women with and without premenstrual syndrome.

Methodologic errors have compromised previous attempts to establish the relationship between mood and menstruation in women with the premenstrual syndromes. These syndromes cannot be diagnosed by history and require confirmation with longitudinal, prospective ratings. In this paper we present the characteristic pattern of mood changes in women with and without menstrually-related mood syndrome. The theoretical and diagnostic implications of the pattern differences are discussed.
