Abstract
Long COVID is frequently associated with persistent autonomic dysfunction, cognitive impairment, and psychological distress, reflecting sustained neuroimmune and autonomic dysregulation. Effective disease-modifying therapies remain scarce. To evaluate the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on autonomic symptoms, post-traumatic stress symptoms, and cognitive performance in patients with long COVID. In this open-label, single-arm prospective pilot study, seventeen patients with long COVID underwent weekly one-hour taVNS sessions for eight consecutive weeks. Autonomic symptoms were assessed using the Composite Autonomic Symptom Score-31 (COMPASS-31), psychological symptoms using the PTSD Checklist for DSM-5 (PCL-5), and cognitive function using a standardized attention and executive function battery (COGBAT). Outcomes were evaluated at baseline and post-intervention. Paired non-parametric analyses were performed. Following taVNS, autonomic symptoms improved significantly, with mean COMPASS-31 scores decreasing from 33.71 ± 16.81 to 13.78 ± 9.38 (p
