Summary

This review clarifies how physiological mechanisms explain non-epileptiform electroencephalogram (EEG) abnormalities, correlating EEG findings with neuroimaging data. Understanding these EEG patterns aids in diagnosing brain lesions and dysfunction.

Area of Science:

  • Neurophysiology
  • Clinical Neurophysiology
  • Neuroimaging

Context:

  • Review of current knowledge on physiological mechanisms of nonepileptiform EEG abnormalities.
  • Correlation between electroencephalogram (EEG) and neuroimaging findings.
  • Discussion of focal and widespread slow waves, background abnormalities, and rhythmic slow activity.

Purpose:

  • To clarify the correlation between EEG and neuroimaging.
  • To elucidate the physiological underpinnings of EEG abnormalities.
  • To integrate EEG data with structural neuroimaging information.

Summary:

  • EEG phenomena correlate with lesion characteristics like size, location, and type (white vs. gray matter, density).
  • Polymorphic slow activity likely originates in the cerebral cortex due to subcortical deafferentation.

  • Abnormalities in background activity and paroxysmal slow waves suggest thalamic or thalamocortical circuit dysfunction, potentially with cortical pathology.

    • Impact:

    • EEG serves as a functional test, offering complementary information to neuroimaging studies.
    • Enhanced understanding of EEG abnormalities aids in diagnosing brain lesions and dysfunction.
    • Provides a framework for interpreting EEG in conjunction with neuroimaging for comprehensive patient assessment.
