The left hemisphere is usually considered the “dominant” hemisphere because it contains the language centers of the brain for most people. In the vast majority of people, a large left middle cerebral artery (MCA) territory ischemic stroke will cause dysfunction of one or both of the language centers. This will produce either a non-fluent aphasia (injury to Broca’s area in the frontal lobe), fluent aphasia (injury to Wernicke’s area in the posterosuperior temporal lobe), or global aphasia (injury to both). Additionally, though impairment varies with infarct size, large left MCA territory ischemic infarcts also present with right arm greater than leg weakness with sensory deficits, right homonymous hemianopia, and a left gaze deviation.
