Perimenstrual Symptoms and Emotional Dysregulation in Autism

Emotional dysregulation (ED) is defined by difficulties in modulating the experience and expression of emotions, which are characterized by particularly marked reactivity, intensity, and duration. To improve the understanding of ED, its consequences in autistic women, and to be able to offer them appropriate treatments, it seems crucial to investigate the links between ED, known adversities during childhood, and premenstrual dysphoric symptoms. This study aims to characterize the variability of ED throughout a menstrual cycle by measuring it in an ecological real-life context. The variability of ED will be compared to that of women with borderline personality disorder (BPD), women with premenstrual dysphoric disorder (PMDD), and women without a diagnosed disorder.
