Final answer:
A TIA is a temporary disruption of blood flow to the brain that causes temporary loss of neurological function, while a CVA is a stroke that can lead to permanent brain damage.
Step-by-step explanation:
A transient ischemic attack (TIA) and a cerebrovascular accident (CVA) are both related to strokes, but they have some key differences. A TIA is a temporary disruption of blood flow to the brain that causes temporary loss of neurological function, often referred to as a mini-stroke.
A CVA, on the other hand, is a stroke that occurs due to a lack of blood flow caused by a blood clot or bleeding from a broken blood vessel in the brain. Unlike a TIA, a CVA typically results in lasting effects and can cause permanent damage to the brain.
In summary, the main difference between a TIA and a CVA is that a TIA is temporary and does not cause significant long-term damage, while a CVA is a stroke that can lead to permanent brain damage.
