What is the Difference Between CVA and Stroke?
🆚 Go to Comparative Table 🆚A stroke, sometimes referred to as a cerebrovascular accident (CVA) or brain attack, occurs when an area of the brain becomes damaged due to a lack of blood supply, which can be caused by a blocked or ruptured blood vessel. There are two main types of stroke: ischemic and hemorrhagic.
- Ischemic stroke: This is the most common type of stroke, accounting for about 80% of cases. It is caused by a blood clot that blocks or plugs a blood vessel in the brain.
- Hemorrhagic stroke: This type of stroke is caused by a blood vessel that breaks and bleeds into the brain.
A transient ischemic attack (TIA), sometimes called a "mini-stroke," occurs when the blood supply to the brain is blocked for a short period of time.
In summary, a stroke is a brain attack that results from a disruption in blood flow to the brain, causing brain cells to die due to a lack of oxygen and nutrients. A CVA is another term for stroke, and the two main types of stroke are ischemic and hemorrhagic, with TIA being a related but less severe condition.
Comparative Table: CVA vs Stroke
A cerebrovascular accident (CVA), also known as a stroke, is a syndrome characterized by the rapid onset of neurologic symptoms such as hemiparesis, hemianopsia, or difficulties with speech. There are two main types of strokes: ischemic and hemorrhagic. Ischemic strokes occur when blood flow to the brain is blocked by a blood clot, while hemorrhagic strokes result from a ruptured blood vessel. Here is a table summarizing the differences between CVA and stroke:
Feature | CVA (Cerebrovascular Accident) | Stroke |
---|---|---|
Definition | CVA is a rapid onset of neurologic symptoms | Stroke is a type of CVA with blood vessel blockage or rupture |
Types | Not applicable (CVA is an umbrella term for various events) | Ischemic (blockage by blood clot) and Hemorrhagic (ruptured blood vessel) |
Symptoms | Hemiparesis, hemianopsia, speech difficulties | Vary depending on stroke type, may include numbness, weakness, trouble speaking, vision, balance, or paralysis |
It is important to note that CVA is a broader term that encompasses various events, while stroke is a type of CVA specifically related to blood vessel issues. Early diagnosis and treatment are crucial for minimizing complications and long-term deficits in stroke patients.
