Onset of epilepsy and menarche—Is there any relationship?
SummaryPurposeWomen with epilepsy have increased frequency of reproductive health problems compared to women without epilepsy. In puberty, reproductive hormonal changes during sexual maturation may affect epilepsy and induce the debut of seizures as indicated in some studies. On the other hand, epileptic activity affects sex hormone function, which may induce alterations in pubertal endocrine maturation and thereby menarche age. We wanted to investigate the relation between epilepsy and menarche age in a larger population of female epilepsy patients.MethodsA retrospective, questionnaire study of a cohort of 265 female outpatients from three Norwegian hospitals and 142 controls, aged 18–45 years was conducted. Parameters regarding epilepsy and reproductive health issues were registered. Perimenarche was defined as 2 years before and 2 years after the year of menarche.ResultsThere was a significantly higher frequency of patients with epilepsy debut between 10 and 18 year compared to 0–9 years (p<0.01). There was, however, no significant difference in occurrence of epilepsy debut in the perimenarche period compared to the 5 year periods before and after perimenarche, and no significant difference in epilepsy debut in the year of menarche compared to the 5 years before or after. Menarche age was not significantly different in those with epilepsy debut before or after menarche. Epilepsy type (idiopathic generalised or partial) did not influence the menarche age.ConclusionsThe study did not confirm the former observations of clustering of epilepsy debut at menarche or in the perimenarche period or alterations in menarche age in girls with epilepsy. However, onset of epilepsy is more frequent in the adolescent years (10–18), than in childhood (0–9)
