Evidence-based treatments for cluster headache

Area of Science:

• Neurology
• Pain Medicine

Background:

• Cluster headache (CH) is an extremely painful neurological disorder.
• Acute attacks require rapid-acting treatments due to their severity and brevity.
• Preventive strategies are necessary for frequent or chronic cases.

Purpose of the Study:

• To review the pathogenesis of cluster headache.
• To evaluate the evidence supporting current acute and preventive treatment options for CH.
• To discuss emerging surgical interventions for refractory CH.

Main Methods:

• Review of existing literature on cluster headache treatment.
• Analysis of clinical evidence for acute therapies like oxygen inhalation and subcutaneous sumatriptan.
• Evaluation of preventive medications, particularly verapamil.
• Assessment of surgical options, including hypothalamic deep brain stimulation.

Main Results:

• Oxygen inhalation and subcutaneous sumatriptan are effective acute treatments for CH.
• Verapamil is the most effective preventive medication, though evidence is limited for many agents.
• Current treatments can be ineffective for chronic or refractory CH.
• Hypothalamic deep brain stimulation is a promising surgical option for severe, refractory cases.

Conclusions:

• Effective acute and preventive treatments exist for cluster headache, but evidence quality varies.
• Management of chronic refractory cluster headache may require advanced interventions like deep brain stimulation.
• Further research is needed to strengthen the evidence base for CH therapies.
