Which of the following is NOT typically associated with a Carotid Artery TIA?

In the context of carotid artery transient ischemic attacks (TIAs), the primary symptomatology is related to the hemisphere of the brain that is supplied by the affected carotid artery. Carotid artery TIAs are characterized by focal neurological deficits that are typically unilateral, meaning they affect one side of the body.

Bilateral vision loss (as noted in the correct answer) is not commonly associated with carotid artery TIAs. This is because the blood supply to both visual fields primarily comes from the posterior cerebral arteries, which are not directly affected by carotid artery occlusions. Therefore, when carotid artery circulation is compromised, the resulting symptoms tend to manifest as unilateral deficits rather than bilateral ones.

In contrast, contralateral hand/arm weakness and contralateral sensory loss are both classic presentations of TIAs when one hemisphere of the brain is deprived of adequate blood supply due to carotid artery blockage. These symptoms reflect the lateralization of brain function, where one side of the brain controls the opposite side of the body. Ipsilateral amaurosis fugax, which is transient vision loss in one eye due to retinal ischemia, clearly ties in with the carotid arterial supply since the retina is fed by the central retinal artery, a
