n. Abbr. CVA
See stroke1.

cerebrovascular accident (CVA)

an abnormal condition of the brain characterized by occlusion by an embolus, thrombus, or cerebrovascular hemorrhage or vasospasm, resulting in ischemia of the brain tissues normally perfused by the damaged vessels. The sequelae of a cerebrovascular insult depend on the location and extent of ischemia. Paralysis, weakness, sensory change, speech defect, aphasia, or death may occur. Symptoms remit somewhat after the first few days as brain swelling subsides. In the United States, 80% of cerebrovascular incidents are ischemic and 20% are hemorrhagic. Also called brain attack, cerebrovascular insult, stroke.

cerebrovascular accident

Medical jargon or euphemism for any of the events causing STROKE, such as cerebral thrombosis, cerebral haemorrhage or EMBOLISM of a cerebral artery.

cerebrovascular accident

; CVA; stroke rapidly developing focal dysfunction of brain tissue persisting for longer than 24 hours, commonly caused by interruption of normal blood supply to brain or spinal cord (e.g. infarction), exacerbated by atherosclerosis and thrombus formation; 1:3 of those affected by CVA are aged less than 65 years; patients with diabetes mellitus are especially prone to CVA; CVA effects vary widely, and presenting features depend on extent and location of central nervous system damage; third most common cause of death in the UK: 20% die within 1 month of CVA and 50% of survivors show permanent change in physical capability, speech and language, cognitive or emotional function; cause of major mobility impairment, e.g. hemiplegia, with footdrop and circumductory gait; surviving CVA cases are likely to be on lifelong anticoagulant therapy, e.g. warfarin or aspirin

cerebrovascular

pertaining to the blood vessels of the cerebrum or brain.

Patient discussion about cerebrovascular accident

Q. Stroke My granny got stroke. Now she is in the hospital, but she doesn't identify me or my mother. When I asked her what are the season now - she answers that it's winter now. I don't know how to help her. What I have to prepare for?

A. I was sorry to hear about your grandmother. You should remeber that after the initial phase, there may be changes in her functioning, especially with rehabilitation program. It's a vast subject, so you can read about it here (http://www.stroke.org.uk/information/after_a_stroke/), and also talk to other people in the stroke community here (http://www.imedix.com/Stroke)

Q. Migraine stroke Hi, I'm 58 years-old male and I have migraines with aura since age 14. Two weeks ago, I felt weakness in the left side of my body, and at the hospital the doctors told me I had a stroke. I underwent several tests, but they still don't know the cause for the stroke (my lab tests are normal; I don't have diabetes or hypertension). My neurologist said that although it's very rare, he thinks that my stroke was caused by my migraine. I tried to find information about it, but couldn't find much – do you know where I can get some more info? Thanks!

A. I supposedly had two strokes that caused one sided weakness and temporary aphasia. The most recent time it happened, I went to a different hospital's ER where their neurologist and stroke specialist told me I have "complex migraines." Apparently this type of migraine can mimic a stroke with all the symptoms. If you look up "complex migraine" at webmd.com or other similar sites, it will give you more informaton. My opinion, for what it's worth, is that I'd rather have a migraine than another stroke since migraines can be treated with preventive meds and/or meds that help the symptoms once it gets started.

Q. What Are the Risk Factors for Developing Stroke? My father had a stroke recently, at the age of 73. What are the risk factors for developing this?

A. Primary risk factors include:

1) smoking
2) excessive alcohol intake
3) uncontrolled high blood pressure
4) high cholesterol
5) overweight/unhealthy diet
6) illegal drugs/abuse of Rx drugs
7) known or unknown heart problems
8) diabetes
9) known or unknown vascular brain defects - aneurysm, etc.
10)family history of stroke
