How would dizziness typically present in a patient with cervical artery dissection compared to non-vascular vestibular dizziness?

• A. Dizziness is not reproducible with cervical rotation
• B. Dizziness is reproduced with active cervical rotation and stable head
• C. Dizziness is reproducible only with trunk rotation
• D. Dizziness is constant and does not vary with neck movements

Answer: (B)

In cases of cervical artery dissection, dizziness often presents as a manifestation of altered blood flow or irritation of cranial nerves associated with cervical structures. When cervical rotation occurs, it can influence the position of the vertebral arteries, potentially exacerbating symptoms. This symptom presentation is typically characterized by dizziness that is reproducible with active cervical rotation while the head is stable. This is distinctly different from non-vascular vestibular dizziness, which usually does not change based on cervical position.

The reproducibility of dizziness with active cervical rotation indicates a connection between the cervical spine movement and the vascular or neural structures involved. This understanding helps clinicians differentiate the underlying causes of dizziness, providing necessary insights into the patient's condition and guiding appropriate interventions.
