Ischemic Stroke (Anterior Cerebral Artery)

An ischemic stroke in the anterior cerebral artery (ACA) occurs when blood flow to the front part of the brain is blocked, usually by a clot. This artery supplies blood to the medial portions of the frontal lobes and superior medial parietal lobes, which control movement and sensation in the legs and feet, as well as some aspects of behavior and decision-making. When the brain tissue in these areas does not get enough oxygen, it can cause sudden weakness or numbness, especially in the leg on the opposite side of the body. Other symptoms may include difficulty walking, changes in personality, and problems with bladder control. This condition affects the nervous system and can lead to lasting disability if not treated promptly.

Ischemic stroke (anterior cerebral artery) is a type of cerebrovascular accident caused by an occlusion of the anterior cerebral artery, leading to ischemia and infarction of the brain regions it supplies. The ACA primarily perfuses the medial frontal lobes, medial parietal lobes, and anterior corpus callosum. The most common mechanism is thromboembolism from large artery atherosclerosis or cardioembolism. Clinically, it presents with contralateral lower extremity weakness and sensory loss, abulia or akinetic mutism in severe cases, and urinary incontinence due to involvement of the medial frontal micturition centers. The condition is significant because it can cause profound motor and cognitive deficits, impacting patient independence and quality of life. Early recognition and management are critical to limit permanent neurological damage.
