Defining abnormal slow EEG activity in acute ischaemic stroke: Delta/alpha ratio as an optimal QEEG index
Highlights • All QEEG indices (sensitive to power of delta, theta, alpha, and/or beta bands) differed highly significantly between acute ischaemic stroke (IS) and control samples. • Delta/alpha power ratio (DAR) demonstrated maximal accuracy for discriminating between acute IS patients and controls....

| description | Highlights • All QEEG indices (sensitive to power of delta, theta, alpha, and/or beta bands) differed highly significantly between acute ischaemic stroke (IS) and control samples. • Delta/alpha power ratio (DAR) demonstrated maximal accuracy for discriminating between acute IS patients and controls. • DAR 3.7 was 100% sensitive for the presence, of a radiologically-confirmed IS lesion. |
