Which sign indicates double vision in cases of VAD?

• A. Dysphagia
• B. Dysarthria
• C. Diplopia
• D. Dizziness

Answer: (C)

In cases of Vertebrobasilar Artery Dissection (VAD), one of the hallmark signs is diplopia, which is the medical term for double vision. This occurs because VAD can affect the cranial nerves that control the eye muscles, disrupting the coordination needed for normal binocular vision. When these nerves are impaired, it often leads to misalignment of the eyes, resulting in the perception of two images instead of one. Recognizing diplopia as a significant symptom is crucial in the context of VAD, as it may help in the early identification and management of the condition. The presence of double vision can indicate that the brainstem is being compromised or that blood supply is altered, which are critical in diagnosing and taking appropriate action for potential strokes or vascular events. Other symptoms, such as dysphagia (difficulty swallowing), dysarthria (slurred or slow speech), and dizziness, while they can occur in various neurological conditions, do not specifically point to double vision as a primary indicator of VAD. Each of these symptoms can result from different mechanisms and may not directly relate to visual disturbances like diplopia does. Understanding the specific symptom of diplopia within the context of VAD is essential for effective diagnosis and treatment.
