Study Reveals Sleep May Worsen Epilepsy After Seizures

Summary

Story summary

Mayo Clinic researchers report that after a seizure, sleep reinforces seizure pathways, potentially worsening epilepsy.
The study analyzed brain recordings from 11 epilepsy patients and found post-seizure sleep features prolonged non-rapid eye movement (NREM) sleep.
This process, called seizure-related consolidation, strengthens abnormal neural circuits and increases the risk of future seizures.
Intervening during the post-seizure sleep window could disrupt the cycle and guide targeted epilepsy treatments.
