Popis: Introduction: Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) are rare primary headache disorders. Aim: The aim of the study is to describe and compare the clinical characteristics of patients with SUNA and SUNCT. Methods: Patients with SUNCT or SUNA observed in a neurology clinic of a tertiary hospital in India between January 2017 and December 2022 were evaluated. Results: Thirteen patients with SUNA (seven female, 54%) and 16 patients with SUNCT (nine female, 56%) were identified for the evaluation. The mean ages at the onset of SUNA and SUNCT were 36.8.5 ± 8.1 years and 37.2 ± 8.4 years, respectively. The age of onset in our patients was somewhat younger than that of other large series. The demographic and clinical features of SUNA patients were comparable to those of SUNCT patients. Orbital/retro-orbital area was the most common site of pain in both types of headaches. The pattern of pain was noted as single stab (in all patients), repetitive stabs (SUNA vs. SUNCT: 77% vs. 75%), and sawtooth patterns (SUNA vs. SUNCT: 23% vs. 25%). The majority of attacks in both groups lasted less than two minutes. Conjunctival injection and tearing were present in all SUNCT patients (as a part of the diagnostic criteria). The prevalence of conjunctival injection and tearing in SUNA was 46% and 31%, respectively. All patients reported spontaneous attacks. Triggers were reported in seven (54%) patients with SUNA and nine (56%) with SUNCT. Only one patient in each group had a refractory period following a trigger-induced episode. Two patients in the SUNCT group had compression of the trigeminal nerve by a vascular loop. Conclusion: This is the largest case series from India. There were no significant differences between patients with SUNA and SUNCT.
