Nutritional Influences on the Brain in ADHD: Evidence from Neuroimaging Studies.
Review in Neurology international, 2026. 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
BACKGROUND/
objectivesAttention-deficit/hyperactivity disorder (ADHD) is increasingly recognized as a neurodevelopmental condition shaped by early-life biological and environmental factors. Emerging evidence highlights the role of nutrition in modulating key brain processes involved in ADHD, from gestational development through childhood. This review aims to examine how dietary interventions influence neuroimaging outcomes in individuals with ADHD, assessing whether nutritional approaches can modulate brain structure, function, or connectivity.
methodsA systematic search of PubMed, Scopus, and Web of Science was conducted to identify studies examining the effects of dietary interventions on neuroimaging outcomes in individuals with ADHD. Study quality was assessed using Cochrane RoB 2.0, ROBINS-I, the Newcastle-Ottawa Scale, and the JBI Critical Appraisal Checklist, according to study design.
resultsA total of 1059 records were identified, and 4 studies met the final inclusion criteria. The included studies suggest that prenatal vitamin D exposure, omega-3 fatty acids, and micronutrients such as zinc may be associated with structural, functional, and neurometabolic brain characteristics relevant to ADHD. Reported findings included associations with brain volume, glutamatergic regulation, white matter organization, resting-state network integrity, and inattentive symptom.
conclusionsCurrent evidence supports the hypothesis that nutrition may influence neurodevelopmental processes involved in ADHD, including brain maturation and neural network organization. Although findings remain heterogeneous and limited in number, nutrition appears to represent a biologically plausible and potentially modifiable factor within the developmental framework of ADHD. Further longitudinal and multimodal neuroimaging studies are needed to clarify the mechanisms linking nutrition, brain development, and ADHD.
