What symptoms would result from a blood clot blocking the right branch of the middle cerebral artery?
Blockage of the Middle Cerebral Artery (MCA), the blood vessel which provides most of the blood to the brain, would be classified as a stroke, falling under the name Middle Cerebral Artery Syndrome. This refers to any circumstance where the blood flow through the MCA is limited or blocked, and is a type of vascular occlusion. If the MCA is blocked on the right side, the symptoms will largely affect the left side of the body, following the general rule that each brain hemisphere affects the contralateral side of the body. Specific symptoms would include weakness and possible paralysis of the entire left side of the body, general sensory loss on the left side, and visual disorders such as deviation conjugée, where the gaze tends towards the affected side (Wikipedia). Because the blockage is on the right, non-dominant symptoms would be present, such as spatial awareness and motor failure, disconnect from the problem itself (patient would be unaware that he is affected), and loss of the ability to perform learned movement despite deliberate mental intention.
