RESUMO
INTRODUCTION: The incidence of mood disorders and psychopathology is more frequent in patients with epilepsy (PWE) than in the general population. Also, it has been reported that PWE suffer more seizures during certain phases of their menstrual cycle (MC). Still, limited information exists regarding the relationship between the physical and emotional changes during the MC in PWE. Therefore, in this study, we aimed to evaluate the mood and personality traits of PWE during their MC and to compare them with controls. METHODS: A cohort of 22 PWE and nine controls was gathered. All the participants underwent psychiatric, electroencephalographic, and gynecological evaluations. RESULTS: Overall, PWE scored higher in depression compared with controls (pâ¯<â¯0.05), PWE also obtained higher scores for the personality traits of neuroticism and self-isolation (pâ¯<â¯0.05). During the evaluation of the symptoms of premenstrual syndrome (PMS), PWE were more symptomatic during the early follicular (EF) phase in comparison with the rest of the phases of their MC, whereas the control group showed the known premenstrual pattern of symptoms during the late luteal (LL) phase. The frequency of seizures (40.6%) and electroencephalographic abnormalities (34.8%) was also higher during the EF phase of the MC when compared with the other phases of the MC (pâ¯<â¯0.05). CONCLUSIONS: The results of this study suggest that unlike the PMS present in women without epilepsy, PWE appear to show a "menstrual syndrome" that consists of similar mood changes and physical symptoms. This arrangement of symptoms seems to have an impact on the increase in seizure activity.
