Frequency and characteristics of multi‐domain autonomic dysfunction in patients with spontaneous intracranial hypotension

Headache: The Journal of Head and Face Pain, Volume 66, Issue 8, Page 1890-1897, September 2026.
Plain Language Summary Spontaneous intracranial hypotension (SIH) is caused by leakage of cerebrospinal fluid and often produces symptoms that worsen when standing, which may resemble autonomic disorders (conditions related to blood flow and heart rate).

Total blood volume and red blood cell volume are not associated with orthostatic intolerance in adults with myalgic encephalomyelitis/chronic fatigue syndrome

Physiological Reports, Volume 14, Issue 17, September 2026.
Abstract Orthostatic intolerance is common in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and may worsen daily functioning. Although hypovolemia has been proposed as a contributor, its relationship to objective orthostatic abnormalities remains uncertain.

Atypical Autonomic‐Predominant Guillain‐Barré Syndrome With Pandysautonomia Mimicking Parkinsonism and Recurrent Syncope: A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Guillain‐Barré syndrome with pandysautonomia can mimic neurodegenerative and cardiogenic conditions, particularly in elderly patients presenting with autonomic symptoms and parkinsonian features. Timely neurologic evaluation and ganglioside antibody testing—especially anti‐GM2—are essential for accurate diagnosis and the initiation of ...

Perioperative care of an adolescent with postural orthostatic tachycardia syndrome

Saudi Journal of Anaesthesia, 2010
Postural orthostatic tachycardia syndrome (POTS) is a disorder characterized by postural tachycardia in combination with orthostatic symptoms without associated hypotension. Symptoms include light-headedness, palpitations, fatigue, confusion, and anxiety,

Cooccurrence of Postural Orthostatic Tachycardia Syndrome with Two Different Clinical Entities

Case Reports in Pediatrics, 2016
Postural orthostatic tachycardia syndrome (POTS) is an abnormal heart rate response to a positional change. Several potential mechanisms for pathophysiology of POTS are defined. This syndrome can coexist with different clinical situations. In our report,

Reduced Stroke Volume and Brain Perfusion Drive Postural Hyperventilation in Postural Orthostatic Tachycardia Syndrome

JACC: Basic to Translational Science
Summary: Postural hyperventilation has been implicated as a cause of postural orthostatic tachycardia syndrome (POTS), yet the precise mechanisms underlying the heightened breathing response remain unclear.

No increased risk of spinal cerebrospinal fluid leak after spinal manipulative therapy: A retrospective cohort study

PM&R, Volume 18, Issue 8, Page 874-884, August 2026.
Abstract Background Spinal cerebrospinal fluid (CSF) leaks, a rare but debilitating condition, have been described following spinal manipulative therapy (SMT) in case reports. However, the nature of the potential association between SMT and CSF leak is uncertain, and symptoms such as neck pain or headache may reflect preexisting leaks rather than ...

Postural orthostatic tachycardia syndrome in children and adolescents [PDF]

Autonomic Neuroscience, 2018
Postural orthostatic tachycardia syndrome (POTS) affects up to 3,000,000 people in the United States, with at least one-third of them developing POTS before the age of 18. POTS as a disorder is similar in adult and pediatric populations, but there are factors specific to pediatric patients that affect how it presents and how it is experienced that make
