The Full form of MCA is Middle Cerebral Artery. MCA is a condition whereby the blood supply from the Middle Cerebral Artery is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, the corona radiata, globus pallidus, temporal and parietal lobes, caudate and putamen. The MCA is the most common site for the occurrence of brain infraction or ischemic stroke. The MCA is by far the largest cerebral artery and is the vessel most commonly affected by cerebrovascular accident. The MCA supplies most of the outer convex brain surface, nearly all the basal ganglia, and the posterior and anterior internal capsules. The signs and symptoms of MCA are: Hemiparesis of the lower half of the contralateral face, Hemiparesis of the contralateral upper and lower extremities, Sensory loss of the contralateral face, arm and leg, Ataxia of contralateral extremities, Speech impairments/aphasia: Broca’s area, Wernicke’s or Global aphasia as a result of a dominant hemisphere lesion (usually the left brain), Perceptual deficits: hemispatial neglect, anosognosia, apraxia, and spatial disorganization as a result of a non-dominant hemisphere lesion (usually the right brain) and Visual disorders: a gaze preference towards the side of the lesion; contralateral homonymous hemianopsia.
