Elderly patients with syncope are typically not seizure patients, despite some EEG similarities. Syncope involves complex cardiac and cerebral interactions, with epileptiform activity potentially contributing mildly.

Area of Science:

  • Neurology
  • Geriatrics
  • Clinical Neurophysiology

Background:

  • Distinguishing seizure disorders from syncope in the elderly is clinically significant.
  • Electroencephalography (EEG) is a key tool in evaluating these conditions.

Purpose of the Study:

  • To compare EEG findings in elderly patients with definite seizure disorders versus those presenting with syncope.
  • To determine if syncope could be considered a seizure phenomenon in this population.

Main Methods:

  • Comparative analysis of EEG data from 161 seizure patients (302 EEGs) and 122 syncope patients (133 EEGs).
  • Evaluation of specific EEG parameters including etiology, epileptiform discharges, slow waves, and background frequencies.

Main Results:

Related Experiment Videos

  • Seizure and syncope groups differed significantly in etiology, incidence and characteristics of epileptiform discharges, and EEG background activity.
  • While 49% of syncope patients showed epileptiform discharges, their characteristics differed from the seizure group.
  • Syncope etiologies included cerebrovascular (33%) and cardiac (21%) factors.

Conclusions:

  • Syncope in the elderly is generally not a manifestation of a simple seizure disorder.
  • A complex interplay between cardiac and cerebral mechanisms underlies syncope.
  • Epileptiform activity in syncope patients may be mildly epileptogenic and require additional cardiovascular factors for unconsciousness.
