Summary

Digital electroencephalography (EEG) is a reliable replacement for paper EEG, and quantitative EEG aids in seizure detection and monitoring. However, challenges remain, potentially leading to false-positive results in clinical applications.

Main Results:

  • Digital EEG is a suitable replacement for traditional paper EEG.
  • Quantitative EEG techniques are beneficial for epilepsy monitoring, seizure detection, and intraoperative/ICU trend monitoring.
  • Some applications are promising, while others require further development; false-positive results remain a concern.

Conclusions:

  • Digital EEG offers a viable alternative to paper-based methods.
  • Quantitative EEG demonstrates significant clinical value in specific neurological monitoring scenarios.
  • Further research is needed to address limitations and optimize the clinical use of advanced EEG technologies.
