Cognitive and psychological issues in postural tachycardia syndrome
Open accessAbstract
Postural tachycardia syndrome (POTS) is one of the most common forms of chronic orthostatic intolerance. In addition to orthostatic symptoms, many POTS patients report incapacitating cognitive dysfunction or "brain fog" even while lying down or seated. Consistent with these subjective reports, there is accruing objective evidence of specific cognitive difficulties in POTS, with studies showing mild to moderate cognitive impairment using standardized neuropsychological assessment batteries. The precise profile of cognitive dysfunction in POTS patients has been shown to vary among these studies potentially due to the neuropsychological tests used, postural position, comorbidities and length of illness, inclusion of adolescent versus adult patients, and sites of recruitment. The extent of the impact that this cognitive challenge has in patients justifies ongoing investigation and research into lifestyle and pharmacological treatments. Psychologically, patients face challenges congruent with many chronic illnesses, perhaps especially early in adjusting to the condition. POTS patients often exhibit mild to moderate depression symptoms as well as symptoms of anxiety disorders. Since even low levels of anxiety can exacerbate symptoms, and a high number of patients experience sub-clinical low mood and sleep disturbances, there is a likely role for psychotherapy in helping control adjustment-related issues, and possibly aberrant physiology, in POTS.

When anxiety questionnaires included autonomic items, POTS patients did not report symptoms of anxiety disorders more often than control groups, unlike when questionnaires excluded autonomic items.
“previous studies have shown that although POTS patients scored high on a range of anxiety measures; when comparing anxiety questionnaire scores that included autonomic items (such as State-Trait Anxiety Inventory) with those that excluded autonomic items (such as ASI), POTS patients did not report symptoms of anxiety disorders more often than control groups (Raj et al., 2018”
From Self-reported symptom burden in postural orthostatic tachycardia syndrome (POTS): A narrative review of observational and interventional studies (2023) · cites this paper as Raj et al., 2018
Section 2.3 (Anxiety; page unavailable) reports the opposite questionnaire pattern: POTS patients scored as moderately anxious on the Beck Anxiety Inventory, which includes somatic and psychological symptoms, but did not have elevated anxiety on the Anxiety Sensitivity Index, weighted toward psychological symptoms. The section separately reports no increased prevalence of diagnosed anxiety disorders; that finding does not support the claimed reversal of questionnaire results. (LLM, conf=0.90)

Sections 5.4 and 5.5 report evidence for CBT in chronic conditions, including chronic pain, and describe benefits for psychological stress and functioning. They do not establish the claimed evidence for ACT or Autogenic Training, or for improvements across the full list of outcomes, including immune function and heart rate variability.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
