Perinatal insults, genetic susceptibility, and the pathogenesis of neurodevelopmental disorders: from epigenetic remodeling to neural circuit dysfunction-a narrative review.
Review in Translational pediatrics, 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 and Objective: Neurodevelopmental disorders (NDDs)-including autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), intellectual disability (ID), epilepsy, and schizophrenia-affect approximately 10-15% of children worldwide. Emerging evidence suggests that NDDs arise from complex interactions between genetic susceptibility and environmental insults, particularly during perinatal periods. This narrative review aims to synthesize current evidence on the molecular and circuit-level mechanisms linking perinatal insults and genetic vulnerabilities to NDD pathogenesis, and to propose an integrative framework across epidemiology, genetics, epigenetics, and neurobiology. Methods: We searched PubMed/MEDLINE, Web of Science, and Google Scholar for articles published from January 2000 to April 2026, combining terms for NDDs, genetic susceptibility, perinatal exposures, and molecular mechanisms. We prioritized original research, meta-analyses, systematic reviews, and consortium studies; human studies were given precedence, with animal and organoid studies included only when providing unique mechanistic insights. Key Content and Findings: The review covers five themes: (I) genetic architecture from rare variants to polygenic risk; (II) gene-environment interplay, distinguishing true interaction from genetic confounding; (III) epigenetic mediation (DNA methylation, histone modifications, noncoding RNAs); (IV) circuit dysfunction from synaptic/ion channel deficits to brain-wide networks (cortex, cerebellum, thalamus, brainstem); and (V) emerging therapeutic strategies with a translational roadmap. Its distinctive innovation lies in integrating these layers across developmental time, proposing epigenetic remodeling as a key molecular transducer linking early insults to persistent circuit dysfunction. Conclusions: Critical gaps persist-ancestry bias, lack of unified quantitative risk models, and limited therapy translation. Future priorities include diversifying genomic cohorts, establishing multi-omic birth cohorts, developing early-detection biomarkers for the perinatal window, and evaluating targeted interventions in genetically defined subgroups. This integrative framework aims to guide developmentally sensitive, precision-oriented approaches to NDD research and clinical care.
