[Influence of menstruation on epilepsy]

Area of Science:

• Neurology
• Gynecology
• Epileptology

Background:

• Epilepsy affects a significant portion of the population, with potential cyclical patterns in seizure frequency.
• The relationship between the menstrual cycle and seizure activity in women with epilepsy is a complex area of study.

Purpose of the Study:

• To investigate the influence of menstruation on epileptic seizures in women of ovulatory age.
• To compare seizure patterns in epileptic females with general epilepsy populations and age-matched males.

Main Methods:

• A cohort of 1,574 epileptic females (12-50 years) was analyzed for menstruation's impact on fits.
• Comparison groups included general epilepsy patients and 476 age-matched males with monthly seizure rhythms.

Main Results:

• Epilepsy was influenced by menstruation in 353 (22.4%) females.
• Seizure exacerbation predominantly occurred during premenstrual and menstrual phases.
• No significant difference in monthly seizure frequency was found between females and males (14% vs. 16%), questioning a direct menstrual correlation.
• Focal non-temporal abnormalities were more common in females whose epilepsy was affected by menstruation.

Conclusions:

• Menstruation demonstrably influences epilepsy in a notable percentage of women, particularly with seizure worsening during the cycle.
• The lack of significant difference in monthly seizure rhythms between sexes suggests that factors beyond menstruation may drive cyclical epilepsy patterns.
• Focal non-temporal abnormalities characterize menstruation-influenced epilepsy in women.
