Resolution of cerebral pathophysiology immediately following thrombectomy in acute ischaemic stroke: Monitoring via quantitative EEG
Quantitative EEG (QEEG) has demonstrated value in assessment of cerebral pathophysiology following acute ischaemic stroke (AIS; e.g., (Finnigan et al., 2013). Various reports indicate that EEG/QEEG can promptly detect cerebral responses to successful reperfusion therapy, even when this cannot be assessed clinically (Finnigan et al., 2006; de Vos et al., 2008, Finnigan et al., 2013). Additionally QEEG can indicate lack of favourable response to therapy, (e.g. unsuccessful alteplase) and may help expedite decisions regarding intra-arterial interventions (e.g.

Improved cerebral pathophysiology immediately following thrombectomy in acute ischaemic stroke: Monitoring via quantitative EEG

QEEG may uniquely inform and expedite decisions regarding intra-arterial clot retrieval in acute stroke
A recent review highlights that QEEG can uniquely inform ischaemic stroke (IS) management and treatment (). IS produces abnormal, slow EEG activity (delta and theta) and attenuation of faster (alpha and beta) activity (). One key QEEG index is “power” (signal intensity; units microvolts squared) of frequency-specific activity. Numerous studies indicate that global delta and alpha power measures and the delta/alpha ratio (DAR) can uniquely inform IS management (e.g., ). Broadly, DAR below 1 is normative whereas higher values are abnormal (). Several observations indicate that continuous EEG/QEEG can detect cerebral resp...
