[Vomiting: symptom of an epileptic seizure].

The authors present 3 cases of ictal vomiting with 2 seizures recorded on the EEG. The critical vomiting is always sudden, projectile, and lasts a short period. The interictal and ictal EEG recording showed a focus or a seizure involving the frontal temporal regions. The seizures were kept under control by a therapy with carbamazepine. Vomiting can be a particular semiological aspect of a possible seizure as are other vegetative features. The authors stress this critical aspect on one hand differentiating it from non-epileptic ictal phenomena (in particular children's cyclic vomiting), on the other hand from post-ictal vegetative phenomena of a major or partial seizure.
