Brain region and cell type-specific DNA methylation profiles in association with ADHD.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Previous studies identified DNA methylation (DNAm) associations with ADHD in peripheral tissue and the brain. Given that DNAm is highly cell type-specific, it is crucial to understand which cell types are driving the DNAm differences observed in ADHD. Here, we report the first brain cell type-specific epigenome-wide association study (EWAS) for ADHD (25 individuals with ADHD, 33 individuals without ADHD) in postmortem anterior cingulate cortex (ACC) and caudate nucleus (CN) based on epigenomic deconvolution. We identified distinct cell type-specific DNAm patterns in both brain regions. On the single site level, we identified significant associations with ADHD in microglia. We identified that in the ACC most differentially methylated regions (DMRs) differences were driven by glutamatergic neurons, whereas differences in the CN were mainly driven by GABAergic neurons. Enrichment of DMRs implicated genes involved in brain development, both in bulk and on the cell type-specific level. Genome-wide DNAm differences in microglia and GABAergic neurons were enriched in genetic risk variants for ADHD. Lastly, the results of EWAS were dependent on cell type reference panels used in statistical analyses. Altogether, these results could provide new insights into the molecular mechanisms underlying ADHD and considerations for EWAS in brain tissue.
