ABSTRACT
Objectives:
The etiological causes of attention deficit and hyperactivity disorder (ADHD) are not fully understood yet. Recent studies have reported that the anti-oxidant activity is reduced and the oxidative stress is increased in ADHD. The aim of this study is to compare serum antioxidant vitamin levels, which are important components of anti-oxidant defense system, between the children and adolescents with ADHD and healthy controls.
Materials and Methods:
Serum levels of vitamin A, C and E were compared between 39 children and adolescents diagnosed with ADHD and 25 healthy controls with similar age and gender by using clinical evaluation and rating scales.
Results:
There were no significant differences in serum vitamin A,C and E levels between ADHD and control groups.
Conclusion:
This study concludes no significant effect of serum A, C and E vitamin levels on ADHD. There is still need for future studies on larger samples.
