What are the two major types of strokes?

• A. Ischemic stroke and thrombotic stroke
• B. Hemorrhagic stroke and subdural stroke
• C. Ischemic stroke and hemorrhagic stroke
• D. Transient ischemic attack and hemorrhagic stroke

Answer: (C)

The two major types of strokes are ischemic stroke and hemorrhagic stroke. Ischemic strokes are caused by a blockage in a blood vessel that supplies blood to the brain, leading to reduced blood flow and therefore oxygen and nutrient supply to that part of the brain, which can result in brain cell death. This type of stroke can further be subdivided into thrombotic and embolic categories, but both fall under the broader classification of ischemic.

On the other hand, hemorrhagic strokes occur when a blood vessel in the brain ruptures, causing bleeding either within the brain itself or in the surrounding areas. This bleeding increases pressure in the skull, which can damage brain cells and interfere with brain function.

Understanding these two categories helps in diagnosing and determining the appropriate treatment strategies, as the causes and therapies for ischemic and hemorrhagic strokes differ significantly. The other options involve subtypes or conditions related to strokes, but they do not represent the two major classifications recognized in the medical field.
