which artery supplies blood to frontal lobe
Anterior cerebral artery. The anterior cerebral artery supplies most of the superior-medial parietal lobes and portions of the frontal lobes with fresh blood. Blood supply to the brain is essential to its functionality, and a lack of blood flow to the vital processes of the brain can cause serious harm. If blood flow is blocked in the anterior cerebral arteries, paralysis or sensory deficits may occur, or even a stroke. Anterior cerebral arteries supply blood to the frontal lobes' anterior (front) aspects, areas responsible for higher-level cognition, including judgment and reasoning. Blockages of these arteries can result in cerebral dementia and speech difficulties.
