Chronic Cluster Headache with Daily Attacks: What to Do When Standard Preventive Therapy Has Failed
This protocol applies to patients with chronic cluster headache (ICHD-3 3.1.2) experiencing daily attacks — or near-daily attacks with remissions lasting under 3 months — persisting for at least 1 year, in whom adequate standard preventive treatment has not achieved a meaningful reduction in attack frequency.
Clinical Scenario
Chronic cluster headache is the less common presentation of cluster headache, accounting for fewer than 20% of cases (ICHD-3 3.1.2). Attacks occur on a daily basis; when symptom-free intervals do occur, these last fewer than 3 months, with the pattern maintained for at least 1 year.
Previous Treatment — Goal Not Achieved
Standard preventive therapy — including lithium carbonate and alternatives such as topiramate, valproic acid, or melatonin — did not achieve the expected reduction in attack frequency. This protocol addresses the step taken after these agents, noninvasive neuromodulation, and peripheral nerve blocks have all proved insufficient.
Next-Line Approach (Partial Overview)
For this refractory presentation, a targeted interventional neurostimulation approach has demonstrated efficacy in both terminating individual attacks and reducing overall attack frequency. Patient selection criteria, procedural details, and the full management algorithm are available in the complete protocol below.
Treatment Goals
Reduction in attack frequency and termination of attacks.

- In patients suffering from the less common chronic presentation (<20% of cluster headaches, ICHD-3 3.1.2), attacks often occur on a daily basis; if symptom-free periods are experienced, these last <3 months, for at least 1 year.
- Based on consensus, nVNS and SPG stimulation are the most promising approaches and should be discussed with the individual patient.
- SPG stimulation was efficacious in treating attacks and in reducing attack frequency in patients with chronic cluster headache.
