Abstract
Abstract The trigeminal autonomic cephalalgias (TACs) are a group of primary headache disorders characterized by unilateral head pain that occurs in association with often prominent ipsilateral cranial autonomic features (Goadsby and Lipton, 1997). The TACs include cluster headache (CH), paroxysmal hemicrania (PH), short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT), and shortlasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA). CH, PH, and SUNCT are currently grouped into section 3 of the revised International Classification of Headache Disorders (ICHD-II) (Headache Classification Committee of The International Headache Society, 2004) whereas SUNA is described in the appendix section. Hemicrania continua (HC) is currently not considered a TAC, being classified under Section 4, Other Primary Headaches, although one might argue for its inclusion here.
