Management of cluster headache.

Area of Science:

• Neurology
• Pain Medicine

Background:

• Cluster headache affects 0.1% of the population, frequently misdiagnosed as migraine or sinusitis.
• A significant diagnostic delay, averaging 7 years, hinders timely patient care.
• Attacks involve severe unilateral orbital/periorbital pain (15-180 min) with autonomic symptoms and agitation.

Purpose of the Study:

• To highlight the diagnostic challenges and treatment strategies for cluster headache.
• To emphasize the importance of early diagnosis for effective management.
• To review current acute and prophylactic treatment options for episodic and chronic cluster headache.

Main Methods:

• Review of epidemiological data on cluster headache prevalence and diagnostic delay.
• Analysis of clinical characteristics and diagnostic criteria for cluster headache.
• Evaluation of current treatment modalities, including acute attack management and prophylactic therapies.

Main Results:

• Cluster headache is characterized by severe unilateral pain and associated autonomic symptoms.
• Effective acute treatments include oxygen and subcutaneous sumatriptan.
• Verapamil is the first-line prophylactic treatment, with higher doses often required.
• Alternative and add-on therapies include corticosteroids, nerve blocks, lithium, and neuromodulation for refractory cases.

Conclusions:

• Despite available treatments, delayed diagnosis remains a major challenge in cluster headache management.
• Prompt recognition of characteristic symptoms by primary care physicians is essential for referral to specialists.
• Comprehensive management strategies, combining acute and prophylactic treatments, can significantly improve patient outcomes.
