While hormonal changes have been recognised to influence seizure control and have been studied in association with menstrual cycles and pregnancy, there is a paucity of data on the menopause transition in epilepsy. Given the known effects of sex steroid hormones on neuronal excitability, their endogenous fluctuations during perimenopause, as well as menopause hormone treatments, may alter seizure control. Epilepsy may also be associated with premature ovarian insufficiency and early menopause. This is especially important for epilepsy-related comorbidities, for which menopause can constitute a second hit, such as osteoporosis. Additional considerations for females with epilepsy across the menopause continuum include changes in antiseizure medication clearance and potential interactions with menopausal hormone therapy or other concomitant medications. This comprehensive review summarises the currently available literature on epilepsy and menopause, highlights gaps in knowledge, and underscores the need for research efforts, particularly longitudinal studies investigating the menopause transition.

A 46-year-old man, an immigrant from Central America, presented to the emergency department after a motor vehicle collision. He had developed a progressive headache over the previous 48 hours, which had suddenly worsened while driving, causing him to crash. There was no significant head trauma. Clinical and radiological findings prompted a workup for atypical subarachnoid haemorrhage.
