[Nutrition intervention in the management of attention deficit hyperactivity disorder in children].

Attention Deficit Hyperactivity Disorder (ADHD) is a chronic neurodevelopmental disorder with an estimated prevalence of approximately 6.4% among children and adolescents aged 6 to 16 in China. The etiology and pathogenesis of ADHD remain incompletely understood, and conventional treatment methods often have limited effectiveness. With advances in research into the etiology of ADHD, nutritional intervention has emerged as a potential adjunctive treatment and has garnered widespread attention. Multiple studies have demonstrated the potential effectiveness of nutritional interventions for ADHD. This review aims to summarize the progress in nutritional interventions for pediatric ADHD, particularly focusing on nutrient-level interventions (including polyunsaturated fatty acids, minerals, and vitamins), nutrition-related factors (such as probiotics), as well as the combined use of multiple nutrients and dietary nutrition (including dietary patterns). We will analyze and discuss the effectiveness of different nutritional interventions to provide a valuable reference for clinical nutritional diagnosis and treatment of the disease.
