What happens if the anterior cerebral artery is damaged?
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.
What symptoms could be associated with damage to the anterior cerebral artery?
Distinctive symptoms in ACA territory infarction include altered mental status, abulia, mutism, decreased verbal fluency, aphasia, and urinary incontinence [3, 4]. Abulia and mutism are associated with cingulate gyrus and supplementary motor area involvement; these areas are important for human behaviour [17,18,19].
Why does anterior cerebral artery stroke cause urinary incontinence?
Lesions of the medial frontal micturition center can result in the activation of the pontine and spinal micturition centers when the bladder is full, causing urinary incontinence.
What causes anterior cerebral artery stroke?
The risk factors and etiology of strokes in this vascular territory are largely the same as for the other principal cerebral arteries including hypertension, dyslipidemias, diabetes mellitus, smoking, atherosclerosis, and cardioembolism.
Does everyone have an anterior communicating artery?
The anterior communicating artery (AComm) is a short vessel that connects the left and right anterior cerebral arteries, forming the anterior border of the cerebral arterial circle of Willis….Anterior communicating artery.

What is an anterior cerebral artery infarct?
Anterior cerebral artery (ACA) infarct. Anterior cerebral artery (ACA) territory infarcts are much less common than either middle or posterior cerebral artery territory infarcts .
Can MRI predict stroke mechanisms of anterior cerebral artery infarction?
Background: Stroke mechanisms and clinical features of anterior cerebral artery (ACA) territory infarction have rarely been investigated using MRI. Objectives: To verify stroke mechanisms and to make clinical imaging correlation. Methods: Clinical, MRI, and angiographic findings of 100 consecutive patients with ACA infarction were studied.
How common are anterior cerebral artery (ACA) territory infarcts?
Anterior cerebral artery (ACA) territory infarcts are much less common than either middle or posterior cerebral artery territory infarcts. ACA territory infarcts are rare, comprising ~2% of ischemic strokes 1,2.
What is the pathophysiology of anterior cerebral artery atherosclerosis?
Conclusion: Anterior cerebral artery (ACA) atherosclerosis is the most important stroke etiology in our population, causing infarction with various mechanisms. Topographic lesion patterns and consequent clinical features of ACA infarction are determined by diverse pathogenic mechanisms and the status of collateral circulation.
