DOI: 10.1002/ana.25147
Abstract: Restoring the circulation is the primary goal in emergency treatment of cerebral ischemia. However, better understanding of how the brain responds to energy depletion could help predict the time available for resuscitation until irreversible damage… read more here.

Cilostazol decreases duration of spreading depolarization and spreading ischemia after aneurysmal subarachnoid hemorrhage

DOI: 10.1002/ana.25361
Abstract: Traditionally, angiographic vasospasm (aVS) has been thought to cause delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH). However, successful treatment of aVS alone does not result in improved neurological outcome. Therefore, there may be… read more here.

Monitoring Cortical Spreading Depolarization: Advancements and Applications in Neurocritical Care: A Scoping Review

DOI: 10.1002/syn.70021
Abstract: Cortical spreading depolarization (CSD) describes a slow, sustained depolarization within the cerebral gray matter that renders neurons unable to fire action potentials, resulting in widespread neuronal depression. CSD has been observed in stroke, subarachnoid hemorrhage,… read more here.

Direct electrophysiological evidence that spreading depolarization-induced spreading depression is the pathophysiological correlate of the migraine aura and a review of the spreading depolarization continuum of acute neuronal mass injury

DOI: 10.1007/s11357-019-00142-7
Abstract: Spreading depolarization is observed as a large negative shift of the direct current potential, swelling of neuronal somas, and dendritic beading in the brain’s gray matter and represents a state of a potentially reversible mass… read more here.

DOI: 10.1007/s12975-024-01242-z
Abstract: The recently published DISCHARGE-1 trial supports the observations of earlier autopsy and neuroimaging studies that almost 70% of all focal brain damage after aneurysmal subarachnoid hemorrhage are anemic infarcts of the cortex, often also affecting… read more here.

DOI: 10.1016/j.nbd.2018.07.026
Abstract: Recurrent spreading depolarizations occur in the cerebral cortex from minutes up to weeks following acute brain injury. Clinical evidence suggests that the immediate reduction of cerebral blood flow in response to spreading depolarization importantly contributes… read more here.

DOI: 10.1038/s41598-017-01284-4
Abstract: Spreading depolarizations (SDs) occur spontaneously in the cerebral cortex of subarachnoid hemorrhage, stroke or traumatic brain injury patients. Accumulating evidence prove that SDs exacerbate focal ischemic injury by converting zones of the viable but non-functional… read more here.

DOI: 10.1038/s41598-017-07119-6
Abstract: Spreading depolarization (SD) is a slow propagating wave of strong depolarization of neural cells, implicated in several neuropathological conditions. The breakdown of brain homeostasis promotes significant hemodynamic and metabolic alterations, which impacts on neuronal function.… read more here.

Abstract: The ability of chill-sensitive insects to function at low temperatures limits their geographic ranges. They have species-specific temperatures below which movements become uncoordinated prior to entering a reversible state of neuromuscular paralysis. In spite of… read more here.
