Clinical insights for early detection of acute transverse myelitis in the emergency departement
… by motor weakness, sensory changes, and autonomic dysfunction. However, diagnosis of ATM is based on early-stage clinical features only (and clarification of the cause of disease), which are difficult for emergency department (ED) physicians owing to low incidence rates. We performed …

ALTERED HEMODYNAMIC, NEUROHUMORAL, AND BRAIN METABOLITE PROFILES IN CHILDREN WITH ORTHOSTATIC INTOLERANCE AND CHRONIC NAUSEA
Orthostatic Intolerance (OI) is a type of autonomic dysfunction affecting >500,000 adults and children in the United States. Upon standing, subjects with OI have impaired blood pressure (BP) regulation that leads to debilitating symptoms of dizziness, fatigue, nausea, and fainting. The development …

What Resonates with you? Methods of Induced Cardiovascular Resonance
Patients with autonomic dysfunction have benefited from balancing of parasympathetic and sympathetic activity through the practice of slow breathing exercises. In preliminary studies, patients with various autonomic dysfunctions used biofeedback of respiratory activity to slow breathing to a …
