what is the difference between TIA and CVA?

Answer 1

TIA or mini stroke results from a small blood clot causing symptoms of stroke but lasts only 24 hours. The importance of this, is that if you don't do some thing about it, you are more likely to have CVA or stroke in the future. CVA is a stoke ( part of the brain has been damaged irreversibly).
Hope that helps

Answer 2

Tia Vs Cva

Answer 3

It's actually important to distinguish between the two.

CVA (cerebro vascular accident) is an umbrella term covering both TIAs and Strokes. It's a term used in hospitals, when a patient first presents as you don't know whether or not it's going to be a TIA or a stroke at thsi point. (usually within 24 hours) It is a term that should not be used after a formal diagnosis has been made as it is entirely unhelpful as it doesn't say what's happened.

TIAs are defined as a "focal neurological lesion lasting less than 24 hours" but they usually have resolved within 1-2 hours and you'd be a bit surprised if it took any longer.

After you're past the 24 hour mark it should be defined medically as a stroke which is either due to a blood clot (ischemic) or a bleed (heamorrhagic) and by the part of the brain it has affected (known as the Oxford classification).

CVA is an incredibly unhelpful term and is literally used as short hand for both TIAs and strokes, but when describing as specific patient should never be used as it tells you nothing

Answer 4

TIA is a trans ischemic attack
CVA is a cerebral vascular accident

TIA's can mean that if you do not get help you can get a CVA.
TIA's are for a short while (trans) there is not enough oxygen (ischemic) to a part of the brain. It is temporary.
CVA's are a permanent damage to a part of the brain affecting part of the body. Sometimes it gets better, sometimes not.

Answer 5

A TIA is exactly what its called. It is a transient event of low oxygen to the brain. It may be a warning signal of a CVA to come. A CVA can be ischemic, where the blood flow to the brain is reduced or stopped by a spasm in the blood vessels or be a clot or other foreign body blocking the blood flow. It can also be hemorrhagic, in which a blood vessel leaks blood into the surrounding tissue.

Answer 7

All CVA's start as a TIA. If the TIA persists past 24 hours it is considered a CVA.

Answer 8

My understanding, though I'm not, in any way medically qualified, is that a TIA (transient ischaemic attack), sometimes referred to as a 'mini-stroke' is, generally, more of a short-term complaint, (which may need treatment to rectify matters) where people make more of a recovery. A CVA (cerebrovascular accident) is a 'full' stroke. These, generally, take a longer time to overcome, and is not always fully recovered from. This is due to a full blockage of a blood vessel, which may need treatment to break down the blockage, before any recovery can be made.

Answer 9

TIA is due to a transient block in a blood vessel, which is relieved in a few minutes without permanent damage. In cva, the block lasts longer and the effects take days or months to heal and may be permanent.

Answer 10

TIA = transient ischemic attack...in layman terms, temporary stroke. CVA= cerebral vascular accident...in layman terms, a stroke with more permanent damage. TIA's are usually called mini-strokes and unfortunately can occur more than once, leading up to a CVA. With TIA's the "damage" is temporary, minor and fleeting. With CVA's - damage is more severe and can involve paralysis.
