* Most common * Contralateral hemiparesis * Sensory loss of face * Homonymous hemianopsia * Aphasia in (L) hemisphere * Perceptual deficits in (R) hemisphere* (R) side of this lacks insight into deficits * Supplies lateral aspect of cerebral hemisphere (frontal, temporal, and parietal lobes)
A
Anterior Cerebral Artery (ACA)
B
Middle Cerebral Artery (MCA)
C
Posterior Cerebral Artery (PCA)
D
None of the above
Explanation: 

Detailed explanation-1: -Contralateral hemiparesis and hemisensory loss of the lower extremity is the most common symptom associated with ACA syndrome.

Detailed explanation-2: -MCA strokes are generally caused by a blood clot that travels from outside the brain. Typically, it’s from the heart or carotid artery. Then the clot gets lodged in the MCA and blocks blood flow.

Detailed explanation-3: -People who have experienced brain injuries to the non-dominant hemisphere typically experience problems on the opposite side of their body, as well as problems with spatial judgment, and with understanding and remembering things.

Detailed explanation-4: -As described previously, MCA strokes typically present with the symptoms individuals associate most commonly with strokes, such as unilateral weakness and/or numbness, facial droop, and speech deficits ranging from mild dysarthria and mild aphasia to global aphasia.
