What typical symptom triad is associated with carotid artery occlusion?

The symptom triad associated with carotid artery occlusion includes headache, ipsilateral Horner’s syndrome, and contralateral hemiparesis. This triad arises due to the disruption of blood flow to specific brain regions as well as involvement of the sympathetic pathways.

Headache is often a result of the irritation of the carotid artery and potentially ischemia. Horner’s syndrome occurs when there is damage to sympathetic nerves to the eye, which can happen due to carotid artery occlusion. This results in ptosis (drooping of the eyelid), miosis (constricted pupil), and anhidrosis (lack of sweating) on the affected side. Contralateral hemiparesis refers to weakness or paralysis on one side of the body opposite to the side of the blockage. This is due to the neurological pathways that govern motor control crossing over to the opposite side of the brain.

The other options do not encompass the hallmark triad associated with carotid artery occlusion, which is why those combinations of symptoms are less indicative of this condition.
