Area of Science:

  • Neuroscience
  • Medical Technology

Background:

  • Automated detection of interictal epileptiform discharges (IEDs) is crucial for epilepsy diagnosis.
  • Evaluating the performance of commercial software packages is essential for clinical application.

Purpose of the Study:

  • To compare the performance of three commercial automated spike detection software packages: Persyst, Encevis, and BESA.
  • To determine which software package offers the best performance in detecting IEDs.

Main Methods:

  • Thirty prolonged EEG records from individuals aged 16 years and older were analyzed.
  • Interictal epileptiform discharges (IEDs) were marked by three human experts and by each software package.
  • Performance metrics including Kappa scores, sensitivity, and specificity were calculated, using expert consensus as the gold standard.

Main Results:

  • Persyst achieved 95% sensitivity (30-min epochs) and 82% (10-sec epochs), with 88%-99% specificity.
  • Encevis showed 86% sensitivity (30-min epochs) and 61% (10-sec epochs), with 88%-99% specificity.
  • BESA had 40% sensitivity and 100% specificity, with low interrater agreement.

Conclusions:

  • Persyst automated software provides IED detection performance comparable to human experts.
  • Persyst outperforms Encevis and BESA in IED detection accuracy.
  • These findings assist clinicians in selecting appropriate automated EEG analysis software.
