Cluster headache prophylaxis has been explored using neurostimulation approaches that target the circuits thought to drive CH, especially the hypothalamic region and the trigeminovascular pathway. The posterior hypothalamus appears to play a key role in the circadian pattern of attacks, so stimulating this area with deep brain stimulation aims to modulate hypothalamic output and reduce attack frequency. At the same time, occipital nerve stimulation targets peripheral input to the trigeminal system, helping to dampen pain signaling and autonomic features during a cluster period. These approaches have been studied particularly in refractory CH and have shown potential benefit, making them among the best-supported neurostimulation options for CH prophylaxis. Other methods like frontal cortex stimulation, vagus nerve stimulation, or transcranial magnetic stimulation of the motor cortex have less robust evidence for CH prophylaxis, which is why they are not as established for this purpose.
