Left Inferior Division MCA Infarct Deficits

Visual and Sensory Deficits

The International Journal of Stroke reports that right homonymous hemianopsia occurs due to involvement of the optic radiations coursing through the temporal and parietal lobes supplied by the inferior division, affecting the right visual field in both eyes 1, 2
The International Journal of Stroke also notes that right hemisensory loss affecting the face, arm, and leg can occur, though typically less severe than in complete MCA territory infarcts, with the sensory deficit being more prominent in the face and arm compared to the leg 1, 2

The International Journal of Stroke states that right-sided neglect may occur but is less prominent than in right hemisphere strokes 1, 2
According to the American Heart Association, as referenced in the International Journal of Stroke, visual-spatial processing deficits are generally absent in left inferior division MCA infarcts, as these functions are predominantly right hemisphere-mediated, however this specific fact is noted in Praxis Medical Insights, an alternative source from the International Journal of Stroke notes similar findings 3
