title: Objective assessment of autonomic signs during triggered first division trigeminal neuralgia.
abstract: A total of 26 episodes of V-1 trigeminal neuralgia attacks have been recorded in two female patients. Autonomic phenomena were assessed according to a semiquantitative scale. Attacks lasted 17 +/- 5 s. Mild lacrimation without conjunctival hyperaemia, rhinorrhea or ptosis was observed, even in relatively long lasting episodes. This is in clear contradiction with SUNCT (shortlasting, unilateral, neuralgiform headache with conjunctival injection, tearing and rhinorrhea) attacks that are always dramatically accompanied by both lacrimation and conjunctival injection of the symptomatic side from the very onset of symptoms. Carbamazepine provided complete and sustained relief of symptoms in both patients. Herein we will show differential autonomic features of V-1 trigeminal neuralgia vs. SUNCT that will both aid the clinician to distinguish both syndromes and stress that both entities are nosologicaly different.
