Area of Science:

  • Neurology
  • Neurosurgery
  • Epileptology

Background:

  • Severe epilepsy with frequent partial seizures has limited treatment options, with only 15% of patients improving with further drug therapy.
  • Epileptic seizures cause neuron loss, mental deterioration, and increased mortality, necessitating effective treatments.
  • Surgical resection of the epileptogenic zone offers a potential cure for epilepsy.

Purpose of the Study:

  • To evaluate the efficacy of epilepsy surgery in achieving seizure freedom.
  • To compare surgical outcomes for different epilepsy types (mesial temporal sclerosis, lesional vs. non-lesional cortical epilepsy).
  • To assess the role of advanced neuroimaging and invasive monitoring in localizing the epileptic focus.

Main Methods:

  • Review of surgical outcomes for various epilepsy types.

Related Experiment Videos

  • Utilizing volumetric MRI, MR spectroscopy, SPECT, and PET to reduce the need for invasive monitoring.
  • Employing invasive recordings when non-invasive methods fail to identify the epileptic focus.

    • Main Results:

    • Surgery for mesial temporal sclerosis and lesional cortical epilepsy achieves 70-80% seizure freedom.
    • Non-lesional cortical epilepsy surgery results in 30-40% seizure freedom.
    • Invasive monitoring diagnoses 50% of patients undiagnosed by non-invasive methods, with 70% becoming seizure-free and 10% improving post-surgery.

    Conclusions:

    • Epilepsy surgery is a viable and effective treatment for drug-resistant epilepsy.
    • Advanced imaging and invasive monitoring aid in precise localization of the epileptogenic zone.
    • Considering surgery in children is crucial for optimal vocational outcomes and preventing chronic illness and associated handicaps.
