Abstract
Twenty-four articles were identified, including 20 studies on autism spectrum disorder (ASD) and 4 on attention-deficit hyperactivity disorder (ADHD).
- For ASD, several studies indicated a difference in gut microbiota diversity, although no consistent specific bacterial changes were reported across all studies.
- Common functional characteristics of gut microbiota were identified in individuals with ASD when compared to controls.
- The results for ADHD were more varied, with no definitive differences in gut microbiota composition observed.
- The association between gut microbiota and ADHD remains unclear due to the heterogeneous results across studies.
- Methodological differences among studies hindered the ability to compare findings effectively for both ASD and ADHD.
