Bridge therapy should buy time safely, not delay definitive prevention, and the overlap with cranial neuralgia means localization and phenotype still matter during early follow-up.

Bridge therapy is useful when a new cluster cycle begins before prevention is effective; Occipital nerve block and corticosteroids can provide rapid temporary control; Noninvasive vagus nerve stimulation can help both acute and preventive cluster treatment; Cranial autonomic symptoms arise through the trigeminal-autonomic reflex; Classical trigeminal neuralgia is the most common major cranial neuralgia syndrome
