Cervicogenic headache: diagnostic criteria

Area of Science:

• Neurology
• Pain Medicine
• Headache Disorders

Background:

• Cervicogenic headache (CeH) is a secondary headache disorder.
• Accurate diagnosis of CeH remains challenging due to overlapping symptoms with other headache types.
• Standardized diagnostic criteria are needed for consistent clinical identification and research.

Purpose of the Study:

• To propose and define clear diagnostic criteria for cervicogenic headache.
• To differentiate CeH from primary headache disorders like migraine and tension-type headache.
• To establish criteria based on clinical presentation and diagnostic testing.

Main Methods:

• Review of existing literature on cervicogenic headache pathophysiology and diagnosis.
• Clinical observation and case study analysis.
• Expert consensus on defining key diagnostic features.

Main Results:

• Proposed criteria include unilateral head pain, neck pain/stiffness, and limited neck range of motion.
• Mandatory features: head pain originating in the neck, neck involvement signs/symptoms, and positive response to anesthetic block of a neck structure.
• Optional features: dizziness, phonophobia, photophobia, autonomic symptoms, and visual disturbances.

Conclusions:

• The proposed criteria provide a framework for diagnosing cervicogenic headache.
• These criteria aim to improve diagnostic accuracy and facilitate further research into CeH.
• Distinguishing CeH is crucial for targeted treatment and management strategies.
