Key result
Ischemic lesions decreased the synchrony of alpha band oscillations between affected brain regions and the rest of the brain, which linearly correlated with cognitive and motor deficits.
Why the study?
Does EEG alpha band synchrony correlate with cognitive and motor performance in patients with ischemic stroke?
Population
20 patients three months after ischemic stroke and 19 age-matched healthy participants
Comparison
Ten-minute resting-state electroencephalography… vs Age-matched healthy participants
Design
Cross-sectional

Alpha synchrony may index post-stroke deficits; hypothesis-generating for EEG biomarkers, prospective validation needed.
Case-Control (n=39)
Does EEG alpha band synchrony correlate with cognitive and motor performance in patients with ischemic stroke?
Ischemic lesions decrease alpha band synchrony between affected regions and the rest of the brain, which correlates with cognitive and motor deficits.
Dubovik et al. (2013) conducted a case-control in Ischemic stroke (n=39). Ischemic stroke vs. Age-matched healthy participants was evaluated on Resting-state functional connectivity (FC) assessed via alpha band imaginary component of coherence (IC). Ischemic lesions decreased the synchrony of alpha band oscillations between affected brain regions and the rest of the brain, which linearly correlated with cognitive and motor deficits.
