What is the most common area for a cerebrovascular accident (CVA)?

The most common area for a cerebrovascular accident (CVA), also known as a stroke, is the middle cerebral artery (MCA). The MCA supplies a large portion of the lateral aspect of the cerebral hemisphere, including areas that control motor and sensory functions for the upper limbs and face, as well as language centers in the dominant hemisphere. Occlusion or hemorrhage in this artery can lead to significant neurological deficits, making it the most frequently affected area during a stroke.

The occurrence of CVAs in the MCA region is often due to a combination of factors, including its size and the territory it supplies, which is critical for many major functions in the brain. The MCA's anatomical proximity to the circle of Willis also contributes to its frequent involvement in stroke events.

Other areas, such as the anterior cerebral artery (ACA), posterior cerebral artery (PCA), and vertebral arteries, are important, but they are less commonly affected in comparison to the MCA. The ACA primarily supplies the medial portions of the frontal lobes and the superior medial parietal lobes, which leads to different patterns of deficits when involved in a CVA. The PCA is associated with visual processing and deficits in vision are more common when this artery is affected. Vertebral artery
