N2 - OBJECTIVE: The presence of aura is rare in cluster headache, and even rarer in other trigeminal autonomic cephalalgias. We hypothesized that the presence of aura in patients with trigeminal autonomic cephalalgias is frequently an epiphenomenon and mediated by comorbid migraine with aura.METHODS: The study retrospectively reviewed 480 patients with trigeminal autonomic cephalalgia in a tertiary medical center for 10 years. Phenotypes and temporal correlation of aura with headache were analyzed. Trigeminal autonomic cephalalgia patients with aura were further followed up in a structured telephone interview.RESULTS: Seventeen patients with aura (3.5%) were identified from 480 patients with trigeminal autonomic cephalalgia, including nine with cluster headache, one with paroxysmal hemicrania, three with hemicrania continua, and four with probable trigeminal autonomic cephalalgia. Compared to trigeminal autonomic cephalalgia patients without aura, trigeminal autonomic cephalalgia patients with aura were more likely to have a concomitant diagnosis of migraine with aura (odds ratio [OR] = 109.0, 95% CI 30.9-383.0, p < 0.001); whereas the risk of migraine without aura remains similar between both groups (OR = 1.10, 95% CI = 0.14-8.59, p = 0.931). Aura was more frequently accompanied with migraine-like attacks, but not trigeminal autonomic cephalalgia attacks.INTERPRETATION: In most patients with trigeminal autonomic cephalalgia, the presence of aura is mediated by the comorbidity of migraine with aura. Aura directly related to trigeminal autonomic cephalalgia attack may exist but remains rare. Our results suggest that aura may not be involved in the pathophysiology of trigeminal autonomic cephalalgia.
