The Crucial Role Of Left Middle Cerebral Artery In Ischemic Stroke-Induced Right Sided Hemiparesis

Chronicle 07 Jun 2024

What happens when the left middle cerebral artery is affected by ischemic stroke?

The left middle cerebral artery (MCA) is a major blood vessel that supplies oxygen and nutrients to the left hemisphere of the brain. When the MCA is blocked by a blood clot, it can cause an ischemic stroke, which can lead to right-sided hemiparesis, or weakness on the right side of the body.

The MCA supplies blood to several important brain regions, including the motor cortex, which is responsible for movement, and the sensory cortex, which is responsible for sensation. When the MCA is blocked, these brain regions can become damaged, leading to paralysis or weakness on the right side of the body.

Ischemic stroke is a serious medical condition that can have a significant impact on a person's life. However, there are treatments available that can help to improve outcomes, such as clot-busting medications and surgery.
