CT, computed tomography, EEG, electroencephalography (Color figure online) On initiation of monitoring, clusters of SDs were identified on the depth electrode (Fig. Such EEG correlates are easily identified in patients with hemicraniectomy and have been used to guide clinical care at our institution but have not been apparent in nonoperative cases using standard EEG visualization and analysis [[7]]. Typically monitored with invasive electrocorticography from subdural or depth electrodes [[4]], SDs can also be observed on scalp electroencephalography (EEG) in patients after hemicraniectomy [[5]]. Spreading depolarizations (SDs) are pathologic waves in cerebral gray matter defined by the near complete breakdown of electrochemical membrane gradients, consequent silencing of electrical activity (spreading depression), and, in some cases, associated cytotoxic edema (CE) on magnetic resonance imaging (MRI) [[1]].
