a CT scan is required to definitively distinguish between these two categories of stroke. The use of CT is mandatory due to the opposite management approaches for ischemic vs. hemorrhagic stroke.
Ischemic stroke, which accounts for 87% of cerebrovascular accidents, is responsible for massive global burden both in terms of economic cost and personal hardship. Many stroke survivors face long-term disability—a phenotype associated with an increasing number of genetic variants. While clinical varia...
Arrange emergency neuroimaging, e.g., noncontrast CT head, to rule out intracranial hemorrhage. Treat eligible patients with reperfusion therapy for acute ischemic stroke (e.g., IV thrombolytics, mechanical thrombectomy) Identify inclusion and exclusion criteria. Lower BP to < 185/110 mm Hg prio...

Acute ischemic change on CT is subtle and often does not show infarct until 12–24 h after stroke onset (James et al., 2006). Reading an acute CT scan may not be difficult however it is not self-evident as pointed out by Józwiak and Ostrek (2011). Even DWI may not show the acute...

Within the secondary injury phase after hemorrhagic stroke, although many of the physiological changes in the acute phase, such as cerebral hemorrhage and increased intracranial pressure, gradually subside and the subarachnoid space is progressively cleared of clots, a second focus of neuronal damage occ...
