BACKGROUND: Affective disorders, and possibly also premenstrual dysphoric disorder (PMDD) are risk factors for alcohol abuse in women. Although the majority of prior studies have indicated that alcohol sensitivity does not differ between menstrual cycle phases, patients with PMDD have thus far not been studied. METHODS: We have evaluated the functional sensitivity to a low dose of alcohol in 12 women with and 12 women without PMDD in the mid-follicular and late luteal phases of the menstrual cycle, by comparing the effects of an intravenous alcohol infusion on a number of saccadic eye movement measures, including saccadic eye velocity (SEV), saccade deceleration, and self-rated levels of intoxication. RESULTS: PMDD patients displayed blunted SEV (p<0.01) and saccade deceleration responses (p<0.01) to alcohol infusion in the late luteal phase compared to the mid-follicular phase. Control subjects, on the other hand, did not change their SEV or saccade deceleration responses to alcohol between cycle phases. CONCLUSION: These findings are compatible with altered saccadic eye movement sensitivity in response to alcohol among PMDD patients, particularly in the late luteal phase of the menstrual cycle.
