What are the two types of cerebrovascular accidents (CVAs)?

The correct answer identifies the two primary classifications of cerebrovascular accidents (CVAs) as ischemic and hemorrhagic.

Ischemic strokes occur when there is a blockage in a blood vessel supplying blood to the brain, often due to a clot. This lack of blood flow results in reduced oxygen and nutrient delivery, leading to potential brain damage if not resolved promptly. On the other hand, hemorrhagic strokes happen when a blood vessel in the brain ruptures, causing bleeding within or around the brain. This type of stroke can increase pressure on brain tissues and disrupt normal blood flow, which can also result in significant injury to brain cells.

Recognizing these two categories is crucial because the treatment approaches differ significantly between ischemic and hemorrhagic strokes. Ischemic strokes may be treated with clot-busting medications or procedures, while hemorrhagic strokes may require surgical intervention to repair the damaged vessel and manage the bleeding.

The other options, while they describe various aspects of medical conditions, do not pertain specifically to the categories of cerebrovascular accidents. Acute and chronic refer more broadly to the duration and severity of conditions rather than specific types of strokes, transient and permanent describe the duration of neurological deficits, and palliative and curative relate to treatment
