Cervical arterial dysfunction (CAD) is an area that requires a broader conceptual framework and updated clinical guidelines. CAD can initially manifest as neck and head pain and assessing blood pressure and performing cranial nerve and eye exams may help direct patient management. A new classification system categorizes CAD into 5 classes based on symptoms and risk level to better frame the condition. Evidence around CAD continues to emerge so re-evaluation of current practices is needed.
