"Differentiating anterior from posterior circulation disease based solely on clinical neurologic deficits is a perilous task; neuroimaging is vital to accurately localise cerebral infarction 3."
"unilateral weakness and/or sensory deficit of at least two areas (out of face, arm and leg)"
"Broadly, the most common cause of anterior circulation infarct is embolism, which includes thromboembolism of cardiac origin, alongside atherosclerotic embolism from proximal intracranial vessels, the carotids and aorta 5. Less common causes include vasculopathies, haematologic disorders, hypercoagulability and arterial dissection. Internal carotid artery dissection is a cause of anterior circulation infarct that may occur at any age but is disproportionately common in younger patients 5."
"higher cerebral dysfunction (e.g. dysphasia, visuospatial disorder)"
