Abstract

Summary: Purpose: Psychogenic nonepileptic seizures (PNES) have long been considered as paroxysmal dissociative symptoms characterized by an alteration of attentional functions caused by severe stress or trauma. Although interpersonal trauma is common in PNES, the proposed relation between trauma and attentional functions remains under explored. We examined the attentional processing of social threat in PNES in relation to interpersonal trauma and acute psychological stress. Methods: A masked emotional Stroop test, comparing color‐naming latencies for backwardly masked angry, neutral, and happy faces, was administered to 19 unmedicated patients with PNES and 20 matched healthy controls, at baseline and in a stress condition. Stress was induced by means of the Trier Social Stress Test and physiologic stress parameters, such as heart rate variability (HRV) and cortisol, were measured throughout the experiment. Results: No group differences related to the acute stress induction were found. Compared to controls, however, patients displayed a positive attentional bias for masked angry faces at baseline, which was correlated to self‐reported sexual trauma. Moreover, patients showed lower HRV at baseline and during recovery. Discussion: These findings are suggestive of a state of hypervigilance in patients with PNES. The relation with self‐reported trauma, moreover, offers the first evidence linking psychological risk factors to altered information processing in PNES.

  • Some people with FND show deficits in sensory processing, interoceptive accuracy, biased attention and impairments in motor learning.

    “While individual differences are important, data indicate that some people with FND show deficits in sensory processing, interoceptive accuracy, biased attention and impairments in motor learning.90,91,[179][180][181][182][183][184]”

    From A new science of emotion: implications for functional neurological disorder (2022) · cites this paper as [181]

    The Discussion reports that patients with psychogenic nonepileptic seizures showed an attentional bias toward masked angry faces and describes impaired emotional information processing. This supports the biased-attention part of the claim, but the paper does not establish deficits in interoceptive accuracy or motor learning, or a general sensory-processing deficit. (LLM, conf=0.88)

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.
