What symptoms typically go along with carotid artery disease?

Sometimes none: Carotid artery disease often causes no symptoms at all. Sometimes it's detected accidentally, when a sound ("bruit") is heard in the neck, or a doppler is done because of non-specific symptoms such as dizziness. When it does cause symptoms, it's usually a temporary loss of vision in one eye, or a weakness or numbness on one side of the body.

Risk of stroke: Carotid disease is a risk factor for stroke. Prior to a stroke, a patient may have transient ischemic attacks (tias), which are brief episodes of weakness or numbness on one side of the body, coordination or speech difficulties. A specific TIA attributable to carotid disease is a brief loss of vision in one eye called amaurosis fugax. Treatment of asymptomatic carotid disease is controversial.
