Area of Science:

  • Neuroscience
  • Neurology
  • Medical Imaging

Background:

  • Transient global amnesia (TGA) is a benign memory disorder with unclear pathophysiology.
  • Characteristic clinical and imaging features are known, but underlying brain activity changes require elucidation.

Purpose of the Study:

  • To explore brain activities and elucidate the pathophysiological changes underlying TGA.
  • To investigate quantitative EEG (QEEG) power spectra and network analysis in TGA patients.

Main Methods:

  • Recruited 215 TGA patients and 252 age/sex-matched controls.
  • Performed MRI and quantitative EEG (QEEG) studies, including power spectra and network analysis.
  • Conducted subgroup analyses based on symptom duration, EEG timing, and MRI findings.

Main Results:

  • TGA patients exhibited a global decrease in absolute power across all brainwave bands.
  • Relative alpha wave power decreased, while theta wave power increased, indicating atypical compensation.
  • Network analysis revealed increased activation in alpha1 band-waves in TGA patients, suggesting a compensatory process.
  • QEEG changes were consistent regardless of MRI cytotoxic lesions and persisted up to one week post-onset.

Conclusions:

  • TGA leads to prolonged and widespread alterations in brain activity and connectivity.
  • Quantitative EEG (QEEG) offers valuable insights into the pathophysiology of Transient Global Amnesia.
