Answer: the answer is Cerebrovascular accident.
Explanation: cerebrovascular accident is also known as stroke. It occurs when there is a loss of blood flow and oxygen to the brain due to a blood clot or rupture of blood vessels in the brain.
It is classified into two:
1. Ischaemic stroke
2. Hemorrhagic stroke
Ischaemic stroke occurs due to blockage of the lumen of artery in the brain either from blood cloth in the brain or blood cloth in another part of the body dislodged in the brain. This blockage leads to a decrease in blood volume reaching the brain and consequently leads to decreased oxygen level in the brain.
Ischaemic stroke accounts for 80-85% of cases of stroke.
Hemorrhagic stroke results from rupture of a brain blood vessel preventing blood flow to the brain. It accounts for 15-20% of stroke cases.
Signs and symptoms of cerebrovascular accident include:
1. Difficulty walking
2. Dizziness
3. Loss of balance and coordination
4. Difficulty speaking
5. Numbness or paralysis
6. Blurred vision
7. Sudden headache
