Ictal unilateral arm and hand paresis during complex partial seizures (CPS) can help pinpoint the seizure

Area of Science:

  • Neurology
  • Epileptology
  • Clinical Neuroscience

Background:

  • Complex partial seizures (CPS) are a type of focal epilepsy.
  • Lateralizing seizure onset is crucial for effective treatment.

Observation:

  • Ictal unilateral arm and hand paresis occurred in 5.3% of patients with partial epilepsy during CPS.
  • This paresis was observed during 27 of 34 CPS events.

Findings:

  • The paresis consistently occurred contralateral to the epileptogenic temporal lobe.
  • In some cases, the paretic limb was flaccid, without postictal (Todd's) paralysis.

Implications:

  • Ictal unilateral paresis is a distinct clinical sign differentiating from other seizure manifestations.

  • This behavior aids in lateralizing and localizing the seizure onset zone, particularly in the temporal lobe.
  • Recognition of this sign can improve surgical planning and patient outcomes.
