Previous evidence links gut microbiota to attention-deficit/hyperactivity disorder (ADHD) through the gut-brain axis. However, the specific microbiota contributing to symptoms remain unclear. To characterize the gut microbial profile related to different symptoms and explore the mediation mechanism between microbiota alterations and the core ADHD symptoms, we conducted shotgun metagenomic sequencing and fecal metabolomics analysis on 94 ADHD patients and 94 age- and gender-matched controls….
