Meta Description: Experience sudden neck pain, headache, or dizziness? Learn about vertebral artery dissection (VAD), a serious condition causing these symptoms. This comprehensive guide details VAD symptoms, diagnosis, and treatment. Don't ignore potential signs; early detection is crucial. Read now for vital information on recognizing and managing VAD.
Vertebral artery dissection (VAD) is a serious condition that occurs when a tear develops in the inner layer of the vertebral artery, one of the major blood vessels supplying blood to the brain. This tear can cause blood to leak into the artery wall, creating a blood clot that may partially or completely block blood flow. Understanding the symptoms of VAD is crucial for early diagnosis and treatment, as it can lead to stroke and other life-threatening complications.
Understanding Vertebral Artery Dissection
Before diving into the symptoms, let's briefly understand the anatomy. The vertebral arteries are two major arteries that run up the neck, alongside the spinal column. They join at the base of the skull to form the basilar artery, which supplies blood to the brainstem and cerebellum. A dissection in this artery can disrupt blood flow to these critical areas.
Common Symptoms of Vertebral Artery Dissection
The symptoms of VAD can vary widely depending on the location and severity of the dissection. Some individuals experience only mild symptoms, while others face a devastating stroke. Recognizing these potential signs is key.
Neck Pain
- Character: Often described as sudden, sharp, and severe pain in the neck, possibly radiating to the head or shoulders.
- Onset: The pain can begin spontaneously or follow a minor neck injury, such as a whiplash or even seemingly insignificant twisting movement.
- Severity: The intensity can vary from mild discomfort to excruciating pain.
Headache
- Character: Severe, often sudden onset headache, potentially accompanied by nausea and vomiting. This is not your average tension headache.
- Location: Headache may be localized or diffuse, depending on the location of the dissection.
- Associated Symptoms: Dizziness, visual disturbances, and neck pain often accompany the headache.
Dizziness and Vertigo
- Character: Feelings of lightheadedness, unsteadiness, or a spinning sensation.
- Severity: Can range from mild to severe, potentially leading to falls.
- Associated Symptoms: Nausea, vomiting, and imbalance are common accompanying symptoms.
Neurological Symptoms
- Weakness or Numbness: Weakness or numbness in the face, arms, or legs, usually on one side of the body.
- Vision Changes: Blurred vision, double vision (diplopia), or loss of vision in one eye.
- Speech Difficulties: Difficulty speaking or understanding speech (aphasia).
- Coordination Problems: Difficulty with balance and coordination (ataxia).
Important Note: Not all individuals with VAD experience all these symptoms. Some may only present with mild neck pain, while others experience a full-blown stroke. The absence of classic "stroke symptoms" does not rule out VAD.
Less Common but Significant Symptoms
While the above are the most common symptoms, other signs of VAD may include:
- Horner's syndrome (drooping eyelid, constricted pupil, decreased sweating on one side of the face)
- Tinnitus (ringing in the ears)
- Facial numbness or weakness
- Difficulty swallowing (dysphagia)
When to Seek Immediate Medical Attention
If you experience any of the symptoms described above, especially sudden and severe neck pain accompanied by neurological symptoms, seek immediate medical attention. VAD is a time-sensitive condition, and prompt treatment can significantly improve outcomes and reduce the risk of stroke.
Diagnosis of Vertebral Artery Dissection
Diagnosing VAD often involves a combination of:
- Physical examination: Your doctor will assess your neurological function and check for tenderness in your neck.
- Imaging studies: These may include CT angiography, MRI angiography, or conventional angiography to visualize the vertebral arteries and identify the dissection.
- Doppler ultrasound: This non-invasive test can help detect blood flow abnormalities in the arteries.
Treatment for Vertebral Artery Dissection
Treatment for VAD depends on the severity of the dissection and the presence of symptoms. Options may include:
- Anticoagulant medications: To prevent blood clot formation and further blockage of the artery.
- Antiplatelet medications: To reduce blood clotting.
- Surgery: In rare cases, surgery may be necessary to repair the damaged artery.

Early diagnosis and treatment are crucial for improving outcomes and reducing the risk of complications from VAD.
