Summary

Epilepsy surgery can effectively control seizures in 50-90% of drug-resistant patients when the seizure focus is identifiable. Early presurgical evaluation is crucial for patients not responding to medication, offering a viable treatment option.

Area of Science:

  • Neurology
  • Neurosurgery
  • Epileptology

Context:

  • 20-25% of epilepsy patients remain seizure-free with medication.
  • Intractable epilepsy affects 25-50% of patients, with localized, non-eloquent seizure foci.
  • Hungary has a significant unmet need for epilepsy surgery, with low current surgical rates.

Purpose:

  • To highlight the efficacy of epilepsy surgery for intractable cases.
  • To emphasize the importance of timely presurgical evaluation.
  • To review the diagnostic tools and success rates of epilepsy surgery.

Summary:

  • Epilepsy surgery offers significant seizure relief for drug-resistant cases, particularly temporal lobe epilepsy (60-90% cure rate), lesional neocortical epilepsy (50-80%), and childhood hemispheric epilepsy (70-80%).

  • Presurgical evaluation, including detailed history, high-resolution MRI, and video-EEG monitoring, is essential for identifying surgical candidates and planning resections.
  • Advanced imaging like ictal SPECT and PET, along with intracranial EEG, may be necessary for precise epileptic focus localization.

    • Impact:

    • Epilepsy surgery can significantly improve quality of life for patients with intractable epilepsy.
    • Increased awareness and accessibility of epilepsy surgery could benefit thousands of patients annually.
    • Optimizing presurgical evaluation protocols can enhance surgical outcomes and reduce the burden of uncontrolled seizures.
