Syncope is associated with electroencephalography changes

I read with interest the article by Muppidi et al., titled "The clinical utility of qualitative electroencephalography during tilt table testing" (Muppidi et al., 2018). In a retrospective study, the authors reported qualitative electroencephalography (EEG) findings during tilt-table testing among 87 patients referred for clinical evaluation. Seven patients had neurally-mediated syncope during testing, but only three developed corresponding EEG changes. The loss of consciousness with syncope is caused by impaired cerebral perfusion and consequent neuronal dysfunction.
