詳細な説明
Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. Emerging evidence suggests that neuroinflammation, altered gut microbiota, and impaired neuroplasticity may contribute to ADHD pathophysiology. Nutritional interventions that target these mechanisms may provide additional therapeutic benefit.
This study is a randomized, placebo-controlled, parallel-group clinical trial designed to investigate whether supplementation with prebiotics, probiotics, omega-3 fatty acids, and vitamin B1 can improve ADHD symptoms and related biological markers in children. Sixty-eight participants aged 6 to 12 years with DSM-5 confirmed ADHD will be enrolled and randomly assigned in equal numbers to one of four intervention groups: (1) prebiotics plus probiotics, (2) omega-3 fatty acids plus vitamin B1, (3) combined supplementation, or (4) placebo.
The intervention duration will be 12 weeks. ADHD symptoms and behavioral scores will be assessed at baseline and after treatment using validated rating scales, including Conners 3 and Vanderbilt ADHD forms. Blood samples will be collected at baseline and week 12 for measurement of inflammatory and neuroplasticity biomarkers, including interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), brain-derived neurotrophic factor (BDNF), short-chain fatty acids (SCFA), Claudin-5, and complete blood count parameters.
The primary objective is to determine the effect of supplementation on ADHD symptom scores. Secondary objectives include comparison of treatment groups for biomarker changes and evaluation of associations between biological markers and clinical outcomes. Results may help identify safe adjunctive nutritional strategies for children with ADHD.

Parent and Teacher ADHD Rating
時間枠:Baseline and Week 12
|
Change in Attention-Deficit/Hyperactivity Disorder (ADHD) symptom severity measured using the Conners 3 Parent and Teacher ADHD Rating Scales. The Conners 3 assesses inattention, hyperactivity/impulsivity, executive functioning, learning problems, aggression, and peer relations. Raw scores are converted to T-scores, with higher scores indicating greater symptom severity and functional impairment. Scale Information: T-score range: approximately 40-90 Higher scores indicate worse ADHD symptoms. |

ADHD Diagnostic Parent and Teacher Rating
時間枠:Baseline and Week 12
|
