Area of Science:

  • Neuroscience
  • Medical Imaging
  • Epileptology

Background:

  • Seizure prediction is vital for timely intervention and patient safety.
  • Optical imaging offers high-resolution monitoring of hemodynamic parameters.

Purpose of the Study:

  • To review literature on optical imaging and hemodynamic changes for seizure prediction.
  • To discuss the application of preictal hemodynamic changes in neurosurgery.

Main Methods:

  • Critical literature review of neocortical epilepsy and optical imaging studies.
  • Analysis of preictal hemodynamic changes.

Main Results:

  • Optical mapping studies have identified preictal hemodynamic changes in human and animal neocortex.
  • Hemodynamic parameters are increasingly recognized for their role in seizure localization.

Conclusions:

  • Optical measurements of blood flow and oxygenation are key for predicting and localizing epileptic events.
  • Predicting seizure onsets can enable closed-loop abortive therapies.
