Lancet (London, England)·2025

Epilepsy significantly increases mortality risk. Uncontrolled seizures are a major factor, with patients experiencing seizures having a 40x higher mortality risk than those in remission.

Area of Science:

  • Neurology
  • Public Health
  • Epidemiology

Background:

  • Epilepsy is linked to a 2-3 fold increase in mortality.
  • Mortality causes in epilepsy patients include direct/indirect epilepsy relation, underlying pathology, or unrelated factors.
  • Directly epilepsy-related deaths are infrequent in community settings.

Purpose of the Study:

  • To analyze cause-specific mortality in epilepsy patients.
  • To differentiate between epilepsy-related and unrelated causes of death.
  • To identify risk factors contributing to increased mortality in epilepsy.

Main Methods:

  • Review of cause-specific mortality studies in epilepsy.
  • Classification of deaths into epilepsy-related and unrelated categories.

  • Analysis of mortality data from community-based and hospital/institution-based studies.

    • Main Results:

    • Pneumonia, CNS/non-CNS neoplasias, and cerebrovascular disease are frequent causes of death.
    • Sudden unexpected death in epilepsy (SUDEP) accounts for up to 17% of deaths in institutional settings.
    • Lack of seizure control is a probable significant risk factor for mortality.

    Conclusions:

    • While direct epilepsy deaths are rare, overall mortality is significantly elevated.
    • SUDEP is a notable cause of death in epilepsy, particularly in institutionalized patients.
    • Effective seizure control is crucial for reducing mortality risk in epilepsy patients.
