Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
* 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: -[1] HH can also be characterized as contralateral hemianopsia (unilateral involvement at the optic tract, lateral geniculate nucleus, optic radiations, or occipital cortex opposite to the side of field loss) in contrast to bitemporal hemianopsia (involvement at the optic chiasm).

Detailed explanation-3: -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-4: -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.
