Gut-brain axis in Attention Deficit Hyperactivity Disorder (ADHD): A narrative review of the links between gut microbiota and ADHD pathophysiology
Key Points
ADHD is linked to variations in gut microbiota composition, indicating possible connections to disease mechanisms.
Notably, alterations in bacterial diversity may influence neurotransmitter levels in individuals with ADHD.
Narrative review examined existing literature on gut-brain interactions related to ADHD pathology and gut health.
Findings suggest underlying biological pathways in ADHD could be modulated by gut microbiota, highlighting new therapeutic avenues.
