Prevalence of Central Sensitization in Postural Tachycardia Syndrome

These findings suggest that CSS was common in patients with POTS and may represent a higher-order sequela of cerebrovascular, respiratory, and autonomic dysregulation. This heightened central processing may amplify symptom perception through altered interoceptive signaling. Central sensitization and autonomic impairment may coexist, and management should focus on both conditions.
