ABSTRACT
INTRODUCTION: Hormonal fluctuation is responsible for worsening of epileptic seizures during the menstrual cycle. OBJECTIVE: To identify irregularities in the menstrual cycles of women with mesial temporal lobe epilepsy (MTLE) and extratemporal focal epilepsy (ETFE) and correlate the frequency of seizures during the menstrual cycles. METHOD: We evaluated prospectively women in the menacme with MTLE and ETFE. Calendars were provided for these patients, and they were asked to mark their seizure frequency according to the menses. Calendars were reviewed in each routine medical appointment. RESULTS: Thirty-nine patients with MTLE and 14 with ETFE were evaluated. We registered 211 cycles in the patients with MTLE and 49 in those with ETFE. Irregular menstrual cycles were found in 28 (28/39, 71.7%) patients with MTLE and 6 (6/14, 42.8%) with ETFE (p=0.052). Premenstrual seizure worsening was observed in 46 (21.8%) patients with MTLE and 9 (18.3%) with ETFE (p=0.596). Menstrual worsening was observed in 47 (22.2%) patients with MTLE and 15 (30.6%) with ETFE (p=0.217). Ovulatory worsening was observed in 36 (17%) patients with MTLE and 13 (26.5%) with ETFE (p=0,126). Catamenial worsening was observed in 58 (27.4%) of the patients with MTLE and in 17 (34.7%) of the patients with ETFE (p=0.315). CONCLUSION: There was no difference between the group of patients with MTLE and ETFE regarding the frequency of irregular cycles and seizure worsening during the premenstrual, menstrual, catamenial or ovulatory periods.
INTRODUÇÃO: Admite-se que a flutuação hormonal seja a responsável para a piora de crises epilépticas no período catamenial. OBJETIVO: Identificar irregularidades nos ciclos menstruais de mulheres com epilepsia de lobo temporal mesial (ELTM) e epilepsia focal extratemporal (EFET); e relacionar a frequencia de crises durante o ciclo menstrual. MÉTODO: Avaliamos mulheres na menacme, que apresentem quadro clínico laboratorial compatível com ELTM e EFET. Foram fornecidos calendários para estas pacientes e instruídas para preenchimento correto da menstruação e das crises epilépticas e serão revistos em cada consulta médica rotineira. RESULTADOS: Foram avaliadas 39 pacientes com ELTM e 14 com EFET. Registramos 211 ciclos nas pacientes com ELTM e 49 nas com EFET. Ciclos menstruais irregulares foram apresentados por 28 (71,7%) pacientes com ELTM e 14 (42,8%) com EFEP (p=0,052). Piora pré-menstrual foi observada em 46 (21,8%) pacientes com ELTM e 9 (18,3%) com EFET (p=0,596). Piora menstrual foi observada em 47 (22,2%) pacientes com ELTM e 15 (30,6%) com EFET (p=0,217). Piora ovulatória foi observada em 36 (17%) pacientes com ELTM e 13 (26,5%) com EFET (p=0,126). Piora catamenial foi observada em 58 (27,4%) das pacientes com ELTM e em 17 (34,7%) das pacientes com EFET (p=0,315). CONCLUSÃO: Não houve diferença entre os grupos de pacientes com ELTM e EFET quanto à freqüência de ciclos irregulares e piora das crises nos períodos pré-menstrual, menstrual, catamenial ou ovulatório.
