Final answer:
Hemorrhagic stroke is the most fatal type of stroke, unlike ischemic stroke or transient ischemic attack (TIA), even though it is less common than ischemic strokes.
Step-by-step explanation:
When comparing the different types of strokes, the hemorrhagic stroke is considered to be the most fatal. A hemorrhagic stroke occurs due to bleeding from a broken blood vessel within the brain, which can lead to cell death both from the deprivation of blood flow to brain tissue and from the pressure exerted by the accumulating blood. Although constituting about 10% of strokes, hemorrhagic strokes have a higher fatality rate than ischemic strokes, which are more common but less likely to be fatal.
A transient ischemic attack (TIA), sometimes known as a mini-stroke, does not typically have lasting effects because the blood flow is restored quickly. An ischemic stroke occurs when a blood clot obstructs an artery going to the brain, but with timely treatment, at times recovery can be significant.
