Using Quantitative EEG Spectrograms to Detect Seizure Subtypes

Seizure; 2018 Feb; Goenka et al.


Using quantitative EEG (QEEG) can help differentiate among several types of seizures suggests an analysis of 562 seizures among 58 patitents.

  • Investigators from Montefiore Medical Center and Albert Einstein College of Medicine in New York evaluated the sensitivity of the Persyst 12 QEEG spectrograms for detecting focal, focal with secondary generalized, and generalized onset seizures.
  • Patients included in the analysis had 2 or more seizures successfully recorded during continuous EEG monitoring in the ICU or epilepsy monitoring unit from July 2016 to January 2017.
  • QEEG spectrograms detected seizures with a sensitivity of 43% to 72%.
  • Asymmetry spectrograms generated the highest sensitivity for detecting local seizures (94%).
  • FFT spectrograms were most sensitive for diagnosing secondarily generalized seizures (84%).
  • Seizure detection trend was most sensitive for generalized onset seizures (79%).
