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.

Leptin and ghrelin concentrations and eating behaviors during the early and late luteal phase in women with premenstrual dysphoric disorder.

In this study, we evaluated the changes in leptin and ghrelin concentrations, eating behavior, depression, and impulsivity and their correlations within the luteal phase among women with premenstrual dysphoric disorder (PMDD). In 63 women with PMDD and 53 healthy controls, we prospectively evaluated serum levels of leptin and ghrelin, Body Mass Index(BMI), and self-reported sweet cravings, cognitive restraint, uncontrolled eating, emotional eating, depression, and impulsivity during the early luteal (EL) and late luteal (LL) phases. Compared with the controls, the women with PMDD had higher BMI, higher leptin concentrations in the EL and LL phase, and leptin concentrations increased from the EL to the LL phase. However, there is no significant difference in ghrelin. Women with PMDD increased sweet cravings and uncontrolled eating from EL to LL phase. No significant correlation was observed between the EL-LL changes in leptin or ghrelin concentrations and those in eating behaviors. Both depression and impulsivity correlated with sweet craving and uncontrolled eating. Depression mediated the association between PMDD and uncontrolled eating. The BMI of women with PMDD positively correlated with their EL-LL change in leptin, and LL depression levels and emotional eating. Young women with PMDD had higher leptin concentrations and BMI in the luteal phase. The LL leptin level was not the primary factor responsible for the increased uncontrolled eating of PMDD. Whether the increased eating and depression in the LL phase contribute to the risk of obesity or hyperleptinemia among women with PMDD need to be evaluated in the future.
