Patient LoginThe carotid arteries carry blood to the front of your brain; a key section, which processes speech, movement, thinking and sensory response. Like the coronary arteries, which supply blood to the heart, the carotid arteries can become clogged with fatty substances and cholesterol over time.
If this takes place, blood flow to the brain is reduced, and this can result in a stroke. If blood is prevented from reaching the brain for more than three to six hours, the resulting damage is normally irreversible.
Silent Symptoms
Rather unnervingly, the majority of people with carotid artery disease will experience no symptoms at all. Their first warning sign is actually the stroke itself.
It’s always a good idea to be aware of the symptoms of a stroke, to ensure that you can react as quickly as possible, and prevent permanent damage or death. Symptoms include:
- Weakness or tingling down one side of the face or body.
- Dizziness
- Difficulty speaking
- Loss or blurring of vision
- Difficulty balancing
- Severe headache
- Trouble remembering things / confusion
- Trouble swallowing (dysphagia)
Diagnosing Carotid Artery Disease
As there are often no symptoms accompanying carotid artery disease, it’s incredibly important to have regular physical examinations with a doctor or neurospinal surgeon.
In order to ascertain whether or not you have the disease, it’s likely your doctor will listen to the carotid arteries in your neck using a stethoscope, in order to detect any unnatural rhythms (often referred to as a ‘bruit’).
You may also be referred for an ultrasound, MRA or CTA scan; and if there is cause for concern, it’s possible that your surgeon may suggest a cerebral angiography; an invasive surgical procedure which provides your doctor with the opportunity to observe blood flow through the carotid arteries in real time.
Avoiding Carotid Artery Disease
In addition to getting regular check-ups, it’s advisable to make lifestyle decisions that minimize chances of developing the condition. Smoking is a major contributing factor to carotid artery disease, as is obesity, high blood pressure and lack of exercise.
