Attention, response inhibition, impulsivity, and decision-making within luteal phase in women with premenstrual dysphoric disorder

Cognitive impairment is a key feature of depressive disorder. Various forms of cognitive function have yet to be investigated in women with premenstrual dysphoric disorder (PMDD) during early luteal (EL) and late luteal (LL) phases. Therefore, we evaluated response inhibition and attention in PMDD in these two phases. We also examined the associations between cognitive functions, impulsivity, decision-making style, and irritability. There is a total of 63 female participants with PMDD and 53 controls, as determined through psychiatric diagnostic interviewing and a weekly symptoms checklist. The participants completed a Go/No-go task, Dickman’s impulsivity inventory, Preference for Intuition and Deliberation scale, and the Buss–Durkee Hostility Inventory: Chinese Version-Short Form at the EL and LL phases. The women with PMDD had poorer attention in the Go trials at the LL phase and poorer response inhibition in the No-go trials at the EL and LL phases. Repeated measures analysis of variance revealed an LL exacerbation of deficit in attention among PMDD group. In addition, impulsivity negatively correlated with response inhibition at the LL phase. Preference for deliberation correlated with attention at the LL phase. Women with PMDD experienced LL declined attention and impaired response inhibition across the luteal phase. Response inhibition is linked to impulsivity. The deficit in attention links preference for deliberation among women with PMDD. These results reveal the different courses in different domains of cognitive impairment in PMDD. Further studies are required to elucidate the mechanism underlying cognitive dysfunction in PMDD.
