What's the difference between a tia and a cva?

TIA & Stroke: Transient ischemic attack by definition symptoms resolve within 24 hours, be it slurred speech or weakness of extremity. This is due to temporary occlusion of the aren't decry of the brain. In contrast a stroke with residual defects occur when an artery is completely blocked. At this time it is not reversible.

Deficit: Tia, or transient ischemic attack, as the name suggests comes and goes away without leaving any neurologic deficit behind it. Cva (cerebral vascular accident) is another name for a stroke. It usually causes deficits (weakness, numbness, speech difficulty) that stay.
