Neurocognitive impairments in eating disorders patients with and without comorbid food addiction.
Article in Journal of eating disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundResearch into the presence of Food Addiction (FA) in Eating Disorders (EDs) has gained increasing attention due to its association with greater symptom severity and poorer treatment outcomes. While the clinical and psychopathological significance of FA in EDs is well established, its neurocognitive impact remains largely unexplored. This study had two primary aims: (1) to examine the psychopathological profile and neurocognitive performance of patients with Eating Disorders (EDs), comparing those with Food Addiction (ED FA+) to those without (ED FA-), alongside a Healthy Control (HC) group; and (2) to explore potential correlations between neurocognitive performance and clinical-psychopathological variables.
methodsThe sample consisted of N = 152 female participants that met the following conditions: EDs FA+ (N = 65), EDs FA- (N = 24), and HC (N = 63). All participants completed a comprehensive battery of questionnaires, including the Yale Food Addiction Scale 2.0. (YFAS-2), and others for the assessment of the eating disorder symptoms, general psychopathology, impulsivity and emotion regulation. Decision-making and inhibitory control were assessed using the Iowa Gambling Task and The Connors Continuous Performance Test II.
resultsNeurocognitive differences were moderate, with lower IGT performance in Block 3 and greater CPT variability, especially in the ED FA + group. Although the ED FA + group presented a more severe clinical profile-characterized by heightened eating symptomatology and general psychopathology (ED F - vs. ED FA+: EDI-2 Total score p 0.001 d 0.95; SCL-90R Global Severity Index p 0.008 d 071)-this was not directly associated with greater cognitive impairment.
conclusionsThe results underscore the need to assess Food Addiction in ED patients, as its presence may exacerbate symptom severity. Additionally, the results suggest that patients with EDs could benefit from incorporating cognitive rehabilitation into their treatment plans, regardless of FA status.
