Which of the following is a common sign of carotid stenosis?

Transient ischemic attacks (TIAs) are temporary episodes of neurologic dysfunction caused by a brief interruption in blood flow to the brain, which can occur due to carotid stenosis. Carotid stenosis is the narrowing of the carotid arteries, typically due to atherosclerosis, leading to reduced blood flow to the brain. When this narrowing is significant, especially during activities like mild exertion, it can result in symptoms such as transient ischemic attacks. TIAs might present as sudden weakness, numbness on one side of the body, difficulty speaking, or loss of balance and coordination. Recognizing TIAs is crucial as they can be precursors to a full-blown stroke.

While palpitations, chest pain, and swollen ankles can be associated with cardiovascular issues, they are not specific indicators of carotid stenosis or its direct effects on cerebral blood flow. It's important to focus on cerebrovascular symptoms like TIAs when evaluating potential carotid artery disease.
