This study compared the gut microbiota of children with ADHD with that of a control group of healthy children, and examined their dietary and sleep habits. Ten medication\u2010na\u00efve children aged 612 years who had recently been diagnosed with ADHD and ten healthy controls were included. ADHD diagnoses were confirmed using the Schedule for Affective Disorders and Schizophrenia for School\u2010Age ChildrenPresent and Lifetime Version (K\u2010SADS\u2010PL). Sleep and eating habits were assessed using the 2nd Level Sleep Disorder Short Form, the Children's Eating Behaviour Inventory, and a form to collect sociodemographic and clinical information. The gut microbiota were analysed using 16S NGS metagenome analysis. A significant decrease in the Shannon and Simpson diversity index values was observed in the ADHD group compared to the control group. Despite the presence of a percentage difference, no statistically significant differences were observed between the groups with respect to species, genus, family, order, class or phylum. Following evaluation of the sleep and eating habit scale scores, no statistically significant difference between the groups was determined.These findings suggests that children with ADHD may alter gut microbiota diversity.However, the absence of significant taxonomic differences and the small sample size mean that these results should be interpreted with caution. Further, larger, adequately powered studies are needed to validate these findings and clarify the potential role of gut microbiota in the pathophysiology of ADHD.<\/jats:p>","DOI":"10.1002\/dneu.70057","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T04:20:23Z","timestamp":1788236423000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Does the Gut Microbiota Play a Role in Attention\u2010Deficit\/Hyperactivity Disorder in Childhood?
