Abstract

The Postural Orthostatic Tachycardia Syndrome (POTS) is a condition in which heart rate increases abnormally when the individual assumes an upright position. In addition to the marked tachycardia, presyncope, and syncope, patients with POTS often complain of light-headedness, fatigue, and difficulty in concentrating. The present study assessed individuals with POTS for psychiatric comorbidity, anxiety sensitivity and health related quality of life and examined general cognitive ability. Data was obtained from patients with POTS (n = 15, 12 female, aged 30 ± 3 years) and age matched healthy subjects (n = 30, 21 female, aged 32 ± 2 years). Patients with POTS commonly presented with symptoms of depression, elevated anxiety and increased anxiety sensitivity, particularly with regards to cardiac symptoms, and had a poorer health related quality of life in both the physical and mental health domains. While patients with POTS performed worse in tests of current intellectual functioning (verbal and non-verbal IQ) and in measures of focused attention (digits forward) and short term memory (digits back), test results were influenced largely by years of education and the underlying level of depression and anxiety. Acute changes in cognitive performance in response to head up tilt were evident in the POTS patients. From results obtained, it was concluded that participants with POTS have an increased prevalence of depression and higher levels of anxiety. These underlying symptoms impact on cognition in patients with POTS, particularly in the cognitive domains of attention and short-term memory. Our results indicate that psychological interventions may aid in recovery and facilitate uptake and adherence of other treatment modalities in patients with POTS.

  • Cerebral blood flow reductions, orthostatic symptoms, and cognitive impairment can occur during and after upright as well as seated positions in people with POTS.

    “cerebral blood flow reductions, orthostatic symptoms and cognitive impairment can occur during and after upright as well as seated positions in people with POTS”

    From Self-reported symptom burden in postural orthostatic tachycardia syndrome (POTS): A narrative review of observational and interventional studies (2023) · cites this paper as Anderson et al., 2014

    The Results (Cognitive function in response to head up tilt; page not specified) show impaired attention during 60° head-up tilt in patients with POTS. The Discussion reports reduced cerebral blood flow during head-up tilt, citing earlier research. The paper does not establish that these effects occur after upright positioning or while seated; its comparison position was semi-recumbent. (LLM, conf=0.87)

  • Antidepressant use is likely high in POTS patients, given the high incidence of polypharmacy and the perception of increased depression in this population.

    “Given the high incidence of polypharmacy in POTS patients (10), coupled with the perception of increased depression in POTS patients (74), antidepressant use is likely high in this patient population.”
  • Other studies have suggested that patients with POTS may have increased prevalence of depression and anxiety.

    “However, other studies have also suggested that patients with POTS may have increased prevalence of depression and anxiety 30.”

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.
