Trigeminal Autonomic Cephalalgias (B Vargas, Section Editor)
Part of the following topical collections:
  1. Topical Collection on Trigeminal Autonomic Cephalalgias


Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting neuralgiform headache attacks with cranial autonomic features (SUNA) are rare headache disorders characterized by severe, short-lasting headaches. These headache disorders are often refractory to treatment and can be secondary phenomena. This article reviews the history, pathophysiology, and treatment of these disorders. Both pharmacotherapy and procedural interventions are discussed in context of historical and more recent reports.
