This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether probiotics—live beneficial bacteria that support gut health—might help improve attention and focus in children with mild ADHD. Researchers believe there may be a connection between gut health and how the brain works, sometimes called the 'gut-brain axis.' This trial will see if taking a probiotic supplement over several weeks makes a difference in ADHD symptoms compared to a placebo (an inactive pill).
Many children struggle with attention and focus, and current treatments don't work well for everyone. Scientists have discovered that the bacteria living in our digestive system may influence how our brain functions, so this medication could offer a new, natural way to help support attention in children with ADHD.

If your child is selected for this study, they will receive either the probiotic supplement or a placebo pill to take daily. You'll visit the clinic at scheduled times so researchers can check how your child is doing and ask about any changes in attention or behavior. The study will track your child's symptoms over several weeks to compare how the probiotic group does compared to the placebo group.
