Transcranial magnetic stimulation (TMS) for cluster headache involves non-invasive magnetic stimulation of specific brain regions, particularly the motor cortex, to modulate neuronal excitability and disrupt pain signaling pathways. By delivering focused magnetic pulses, TMS can potentially reduce neuroinflammation, alter cortical excitability, and interrupt the trigeminovascular pain mechanisms associated with cluster headache. Studies suggest that repetitive TMS may have both acute pain-relieving effects and prophylactic potential in managing cluster headache episodes.
