stroke [ strohk ]
Subclass of:
Cerebrovascular Disorders
Also called:
Brain attack; Cerebrovascular accident (CVA)
Definitions related to stroke:
-
(undetermined stroke) An acute episode of focal or global neurological dysfunction caused by presumed brain, spinal cord, or retinal vascular injury as a result of hemorrhage or infarction but with insufficient information to allow categorization as ischemic or hemorrhagic.CDISC TerminologyClinical Data Interchange Standards Consortium (CDISC), 2021
-
A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
Blockage or rupture of a blood vessel supplying the brain; often leads to impaired brain function or death.Harvard Dictionary of Health TermsHarvard Medical Publishing, 2011
-
In medicine, a loss of blood flow to part of the brain, which damages brain tissue. Strokes are caused by blood clots and broken blood vessels in the brain. Symptoms include dizziness, numbness, weakness on one side of the body, and problems with talking, writing, or understanding language. The risk of stroke is increased by high blood pressure, older age, smoking, diabetes, high cholesterol, heart disease, atherosclerosis (a build-up of fatty material and plaque inside the coronary arteries), and a family history of stroke.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021

Sudden impairment of blood flow to a part of the brain due to occlusion or rupture of an artery to the brain.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
Sudden neurologic impairment due to a cerebrovascular disorder, either an arterial occlusion or an intracranial hemorrhage.CRISP ThesaurusNational Institutes of Health, 2006

A stroke happens when there is a loss of blood flow to part of the brain. Your brain cells cannot get the oxygen and nutrients they need from blood, and they start to die within a few minutes. This can cause lasting brain damage, long-term disability, or even death. If you think that you or someone else is having a stroke, call 911 right away. Immediate treatment may save someone's life and increase the chances for successful rehabilitation and recovery. There are two types of stroke: Ischemic stroke is caused by a blood clot that blocks or plugs a blood vessel in the brain. This is the most common type; about 80 percent of strokes are ischemic.; Hemorrhagic stroke is caused by a blood vessel that breaks and bleeds into the brain. Another condition that's similar to a stroke is a transient ischemic attack (TIA). It's sometimes called a "mini-stroke." TIAs happen when the blood supply to the brain is blocked for a short time. The damage to the brain cells isn't permanent, but if you have had a TIA, you are at a much higher risk of having a stroke. Certain factors can raise your risk of a stroke. The major risk factors include High blood pressure. This is the primary risk factor for a stroke.; Diabetes.; Heart diseases. Atrial fibrillation and other heart diseases can cause blood clots that...MedlinePlusU.S. National Library of Medicine, 2021

A stroke occurs when the blood supply to part of your brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes.Mayo Foundation for Medical Education and Research

Stroke, sudden impairment of brain function resulting either from a substantial reduction in blood flow to some part of the brain or from intracranial bleeding. The consequences of stroke may include transient or lasting paralysis on one or both sides of the body, difficulties in speaking or...Encyclopedia Britannica, Inc., 2020
