Ictal vomiting, a seizure symptom, is often linked to the right temporal lobe in epilepsy patients. This symptom can be effectively treated with right temporal lobectomy.

Area of Science:

  • Neurology
  • Epileptology

Background:

  • Ictal vomiting, or ictus emeticus, is an uncommon seizure manifestation.
  • Understanding its neurological basis and treatment is crucial for patient management.

Purpose of the Study:

  • To investigate the characteristics of ictal vomiting.
  • To determine the hemispheric lateralization of seizures causing vomiting.
  • To evaluate the efficacy of surgical intervention for this condition.

Main Methods:

  • Simultaneous video and electroencephalography (EEG) recordings of 31 ictal vomiting episodes in 9 patients.
  • Subdural electrode array recordings in 4 patients.
  • Analysis of seizure semiology, EEG findings, and post-surgical outcomes.

Main Results:

Related Experiment Videos

  • All ictal vomiting events were associated with right-hemisphere ictal epileptiform abnormalities, predominantly involving temporal lobe structures.
  • Eight of nine patients experienced amnesia for the vomiting episodes.
  • Three of four surgically treated patients became seizure-free after right temporal lobectomy.

Conclusions:

  • Ictal vomiting is consistently lateralized to the right hemisphere, often involving the temporal lobe.
  • Patient unawareness and association with other ictal phenomena are key indicators.
  • Right temporal lobectomy can be an effective treatment for refractory ictal vomiting.
