Dizziness, headaches, and blurry vision: the vascular concern

Dizziness, headaches, and blurry vision: the vascular concern. Carotid stenosis refers to the narrowing of the carotid arteries, which are the major arteries that supply blood to the brain. The narrowing is often caused by the buildup of fatty deposits (plaque) on the inner walls of the arteries. Carotid stenosis can increase the risk of stroke if a blood clot forms and blocks the narrowed artery or if a piece of the plaque breaks off and travels to the brain. The severity of symptoms can vary, and in some cases, carotid stenosis may be asymptomatic. Common symptoms and signs associated with carotid stenosis include:

Transient Ischemic Attacks (TIAs): Also known as “mini-strokes,” TIAs are temporary episodes of neurological symptoms that are similar to a stroke but typically last for a short duration. They may include:

Sudden weakness or numbness on one side of the body, usually the face, arm, or leg.

Trouble speaking or understanding speech.

Vision problems, such as blurred or blackened vision.

Stroke: In severe cases, carotid stenosis can lead to a full-blown stroke, which causes more prolonged and severe neurological symptoms.

Speech and Language Difficulties: Difficulty speaking or slurred speech may occur, especially during a TIA or stroke.

Visual Disturbances: Sudden vision loss or blurred vision in one or both eyes may occur.

Dizziness or Vertigo: Some individuals with carotid stenosis may experience dizziness or a spinning sensation.

Balance Issues: Difficulty maintaining balance or coordination.

Severe Headache: In rare cases, severe headache may occur, particularly if a stroke is imminent.

It’s important to note that carotid stenosis can be asymptomatic, and individuals may not experience any noticeable signs until a TIA or stroke occurs. Regular medical check-ups, especially for individuals at higher risk (such as those with a history of cardiovascular disease or risk factors like hypertension and diabetes), are important for early detection and management.

If you or someone else is experiencing symptoms suggestive of a stroke or TIA, it’s crucial to seek medical attention immediately. Please call to set an appointment with our vascular specialists right away. Rapid intervention can help minimize the potential impact of a stroke and improve outcomes. Diagnostic tests such as ultrasound, CT angiography, or magnetic resonance angiography may be used to confirm the diagnosis of carotid stenosis and determine the degree of narrowing in the carotid arteries. Treatment options may include lifestyle changes, medication, or, in some cases, surgical procedures to reduce the risk of stroke.
