Background The physiology underlying "brain fog" in the absence of orthostatic stress in postural tachycardia syndrome (POTS) remains poorly understood. Methods and Results We evaluated cognitive and hemodynamic responses (cardiovascular and cerebral: heart rate, blood pressure, end‐tidal...

Post copied from this thread: EDS, hypermobility, and the link, if any, to ME/CFS I didn't know where to post this, but the ME Association had an online survey about common health conditions in pwME. The current result: Which of the following conditions, which are more common, or appear to be...

Abstract Postural Orthostatic Tachycardia Syndrome (POTS) is a complex, multisystem disorder characterized by orthostatic intolerance and tachycardia and may be triggered by viral infection. Recent reports indicate 2-14% of COVID-19 survivors develop POTS and 9-61% experience POTS-like...

[Anxiety in patients with postural tachycardia syndrome (POTS)] Article in German C Wagner, S Isenmann, H Ringendahl, C-A Haensch Background: The postural tachycardia syndrome (POTS) is a condition of the autonomic nervous system with symptoms of orthostatic intolerance. In POTS patients...

Despite its increasing recognition and extensive research, there is no unifying hypothesis on the pathophysiology of the postural tachycardia syndrome. In this cross-sectional study, we examined the role of fear conditioning and its association with tachycardia and cerebral hypoperfusion upon...

Background: Orthostatic intolerance (OI) is a core finding in individuals with myalgic encephalomyelitis /chronic fatigue syndrome (ME/CFS). Deconditioning is often proposed as an important determinant for OI. Deconditioning can be objectively classified using the predicted peak oxygen...

Introduction: In patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) a higher-than-normal resting heart rate has been reported in a number of studies. As heart rate is linked to stroke volume, the present study explored the relationship between the supine heart rate and...

Detection of G Protein-Coupled Receptor Autoantibodies in Postural Orthostatic Tachycardia Syndrome Using Standard Methodology (the title is a bit misleading, read the whole abstract) Main author is Dr Satish Raj from Calgary. Abstract Background: Postural orthostatic tachycardia syndrome...

Abstract Background: Orthostatic tachycardia (OT) affects some patients after concussion/mild traumatic brain injury (mTBI). In this study, we sought to identify the factors associated with increased risk for OT in patients with mTBI. Methods: We conducted a retrospective review of 268...

Objectives: Pediatric acute-onset neuropsychiatric syndrome (PANS) is characterized by an abrupt-onset of severe psychiatric symptoms including OCD, anxiety, cognitive difficulties, and sleep issues which is thought to be a post-infection brain inflammatory disorder. We observed postural...

Abstract Purpose Postural orthostatic tachycardia syndrome (POTS) is a debilitating and poorly understood disorder of the autonomic nervous system with many different causes, mostly seen in females of child-bearing age. This study used an illness representation framework to explore the lived...

Abstract Background: Postural tachycardia syndrome (POTS) is characterized by excessive upright tachycardia and disabling presyncopal symptoms, which are exacerbated after consuming a high-carbohydrate meal; it is unknown, however, what is the precise underlying mechanism. We seek to...

Abstract Purpose Previous studies demonstrated M2 muscarinic acetylcholine receptor-activating autoantibodies (M2R-AAb) were present in some patients with postural tachycardia syndrome (POTS). This study examines how these autoantibodies might contribute to the pathophysiology of POTS, and...

Abstract In normal subjects natriuresis is tightly coupled to dietary salt ingestion to maintain sodium balance. Likewise, blood pressure remains unchanged over a wide range of salt intake because of pressure natriuresis, whereby an increase in blood pressure stimulates renal sodium excretion...
