A
A rupture of a blood vessel in the brain
B
An infection in the brain tissue
C
A blockage in a blood vessel supplying the brain
D
A genetic mutation affecting brain function
Verified step by step guidance1
Understand the definition of an ischemic stroke: It occurs when there is a blockage in one of the blood vessels supplying blood to the brain, leading to a reduction in blood flow and oxygen to brain tissue.
Differentiate between ischemic and hemorrhagic strokes: Ischemic strokes are caused by blockages, while hemorrhagic strokes are due to ruptures in blood vessels.
Evaluate the options given: A rupture of a blood vessel would indicate a hemorrhagic stroke, not ischemic.
Consider the role of infections: An infection in the brain tissue does not directly cause an ischemic stroke, though it can lead to other complications.
Identify the correct cause: A blockage in a blood vessel supplying the brain is the most accurate description of the cause of an ischemic stroke.
