Epilepsy surgery can improve seizure control, but some patients develop nonepileptic seizures postoperatively. Preoperative psychiatric evaluation may identify individuals at risk for these nonepileptic seizures.

Area of Science:

  • Neurology
  • Psychiatry
  • Epilepsy Surgery

Background:

  • Medically intractable partial epilepsy often necessitates surgical intervention for improved seizure control.
  • While generally effective, epilepsy surgery carries risks, including the potential development of nonepileptic seizures.

Purpose of the Study:

  • To report on a series of patients who developed nonepileptic seizures (pseudoseizures) after epilepsy surgery.
  • To identify common characteristics in patients experiencing post-surgical nonepileptic seizures.
  • To explore the utility of preoperative psychiatric assessment in predicting this adverse outcome.

Main Methods:

  • Case series of six patients who underwent surgery for refractory complex partial seizures.
  • Postoperative confirmation of pseudoseizures using electroencephalogram (EEG) monitoring.

  • Psychiatric assessment of the affected patient group.

    • Main Results:

    • Six patients developed nonepileptic seizures post-epilepsy surgery, confirmed by EEG.
    • Three of these patients had pre-existing nonepileptic seizures alongside their epilepsy.
    • Psychiatric evaluation revealed shared characteristics among these patients.

    Conclusions:

    • Epilepsy surgery can precipitate or unmask nonepileptic seizures in susceptible individuals.
    • Preoperative psychiatric screening may be crucial for identifying patients at risk of developing nonepileptic seizures.
    • Multimodal treatment including anticonvulsants and behavioral therapy is indicated.
