Impaired resting vagal tone in patients with functional movement disorders.

Article Synopsis
- The autonomic nervous system is crucial for maintaining balance in the body, especially during stress, and is linked to functional movement disorders (FMD) due to psychological stress.
- 35 FMD patients and 38 healthy controls were studied through overnight ECG recordings, measuring heart rate variability (HRV) to assess autonomic function.
- FMD patients showed lower parasympathetic activity (measured by RMSSD) and higher heart rates compared to controls, suggesting impaired vagal tone and potential increased stress vulnerability in these patients.
A biological measure of stress levels in patients with functional movement disorders.

Introduction: While the presence of co-existing psychological stressors has historically been used as a supportive factor in the diagnosis of functional neurological disorders, many patients with functional neurological disorders deny the presence of these stressors. The stress response circuitry in these patients remains largely unexplored.
Methods: We performed an observational study examining biological stress levels in patients with functional movement disorders as compared with matched healthy controls.
