Summary
This summary is machine-generated.

Ictal smiling during partial seizures is uncommon but can help localize the seizure focus. This study found smiles occurred in temporal or parietal lobe seizures, often in the right hemisphere.

Area of Science:

  • Neurology
  • Epileptology

Background:

  • Smiling can occur during partial seizures.
  • The diagnostic value of ictal smiling for localizing the epileptogenic zone is not well-established.

Purpose of the Study:

  • To investigate the utility of ictal smiling as a potential indicator for localizing the epileptogenic focus.

Main Methods:

  • Reviewed patients undergoing video-EEG monitoring with ictal smiling as a symptom.
  • Defined ictal smile as an emotional expression during seizures with concurrent epileptic symptoms and EEG activity.

Main Results:

  • Five out of 86 patients exhibited ictal smiling during partial seizures.
  • Smiling was observed in seizures originating from the parietal (2 patients) and temporal lobes (3 patients).
  • The right hemisphere was more frequently implicated in seizures with ictal smiles.

    • Conclusions:

    • Ictal smiling is a rare manifestation of partial seizures.
    • It is associated with seizures involving the temporal or parietal lobes, predominantly in the right hemisphere.
