Catamenial epilepsy, where seizures cluster around menstruation, is uncommon. Patient reports of seizure timing often differ from strict diagnostic criteria, highlighting the need for a standardized definition.

Area of Science:

  • Neurology
  • Gynecology
  • Epilepsy Research

Background:

  • Catamenial epilepsy is defined by seizure occurrence in relation to the menstrual cycle.
  • Accurate identification is crucial for effective epilepsy management.
  • Patient perception of seizure timing may influence diagnosis.

Purpose of the Study:

  • To investigate the prevalence of catamenial epilepsy using a standardized definition.
  • To compare patient-reported seizure patterns with objective criteria.
  • To assess the relationship between premenstrual tension and catamenial epilepsy.

Main Methods:

  • Prospective study of 40 women with refractory epilepsy over 3 months.
  • Detailed recording of seizures, menstrual periods, and premenstrual tension symptoms.

  • Application of a strict definition for catamenial epilepsy (≥75% of seizures within a 10-day window around menstruation).

    • Main Results:

    • Only 12.5% of patients met the strict criteria for catamenial epilepsy.
    • However, 78% of patients claimed most seizures occurred near menstruation.
    • No significant difference in premenstrual tension symptoms was observed between groups.

    Conclusions:

    • Catamenial epilepsy, by strict definition, is uncommon.
    • Patient self-reporting of seizure timing relative to menstruation may be inaccurate.
    • A standardized diagnostic criterion for catamenial epilepsy is essential for clinical management.
