The most common symptom of carotid artery disease is transient ischemic attacks (TIAs) or strokes. Carotid artery disease usually develops due to atherosclerosis, a condition where plaque builds up in the arteries, narrowing them and reducing blood flow to the brain. When this occurs, it can lead to sudden neurological symptoms that are characteristic of TIAs or strokes.

TIAs, often termed "mini-strokes," are temporary episodes that can cause symptoms such as weakness or numbness on one side of the body, sudden confusion, trouble speaking, or visual disturbances. Although they are temporary and resolve within a short time, TIAs are significant warnings of the potential for a more debilitating stroke.

In contrast, symptoms like chest pain, shortness of breath, or a persistent cough typically relate to conditions affecting the heart or lungs rather than carotid artery disease specifically. Therefore, the presence of TIAs or strokes is directly linked to the complications of carotid artery disease, making it the most relevant symptom to recognize in patients with this condition.
