7 de may. de 2024 · Taking these 3 features one at a time, the first step in all circumstances should be to determine stroke severity, best measured by one of a number of stroke scales. 8 This will help determine the underlying pathology; the more severe the neurological deficit, the more likely the patient is harboring a large vessel occlusion or ...
14 de may. de 2024 · Stroke is an acute, focal neurological deficit with no other explanation than a cerebrovascular cause. Common symptoms include hemiparesis, dysarthria, sensory deficits, aphasia, and visual deficits. Globally, with only little variation, ischaemic strokes constitute between 60–70% of all strokes and result from an acute arterial occlusion.
17 de may. de 2024 · Although characterised by mild neurological symptoms, typically ranging from 0 to 5 on the National Institutes of Health Stroke Scale (NIHSS), minor ischaemic stroke is associated with frequent long-term disability and a significant risk of stroke recurrence.
20 de may. de 2024 · Terminology. The term hemorrhagic transformation is somewhat variably used and collectively refers to two different processes, which have different incidence, appearance and prognostic implications. These are: hemorrhagic infarction (petechial hemorrhages) parenchymal hematoma.
20 de may. de 2024 · Ischemic stroke is an episode of neurological dysfunction due to focal infarction in the central nervous system attributed to arterial thrombosis, embolization, or critical hypoperfusion.
8 de may. de 2024 · The National Institutes of Health Stroke Scale (NIHSS) score is a measure of the severity of stroke. NIHSS scores range from 0 to 42, with higher scores indicating more severe neurologic deficits.
7 de may. de 2024 · The ASCOD classification system 1, published in 2013, aims to define phenotypes of ischemic strokes for individual patients by assigning a degree of probability to each of the most common causes of this pathology. It serves most strictly as a research tool but is also useful clinically as a mnemonic to consider common causes of ischemic stroke.
