Catamenial seizures, linked to hormonal shifts during the menstrual cycle, show varied manifestation rates. GnRH-analogue treatment successfully reduced seizure frequency in many epilepsy patients.

Area of Science:

  • Neurology
  • Endocrinology
  • Epilepsy Research

Background:

  • Catamenial seizures are epilepsy events linked to menstrual cycle hormonal fluctuations.
  • Estrogens may increase neuronal excitability, while progesterone can lower it, influencing seizure occurrence.

Purpose of the Study:

  • To investigate the actual incidence of catamenial seizures in women reporting increased frequency.
  • To evaluate the efficacy of a gonadotropin-releasing hormone (GnRH) analogue in managing catamenial seizures.

Main Methods:

  • Studied 21 women with epilepsy reporting catamenial seizure increases.
  • Administered a synthetic GnRH-analogue to 16 patients to suppress gonadotropin release.

Main Results:

Related Experiment Videos

  • Only 24% of women exhibited consistent catamenial seizure patterns.
  • Four of six patients with exclusively catamenial seizures became seizure-free after GnRH-analogue treatment.
  • Seven of ten patients with both catamenial and non-catamenial seizures experienced over 50% seizure frequency reduction.

    • Conclusions:

    • Confirms that not all reported catamenial seizure increases are consistently linked to the menstrual cycle.
    • GnRH-analogue therapy shows promise for managing refractory catamenial epilepsy, particularly in seizure-focused cases.
