Objective: The purpose of this study is to examine the effect of chronic rhinitis treatment on attention-deficit/hyperactivity disorder (ADHD) symptoms in children with ADHD.
Methods: Children and adolescents with ADHD were screened for chronic rhinitis symptoms. Participants with positive chronic rhinitis screening underwent the skin prick test and received rhinitis treatment for 3 months. All participants were evaluated using the parent's and teacher's Vanderbilt ADHD rating scales, total nasal symptom score, and Quality of Life Questionnaire (OSA-18) for pediatric obstructive sleep apnea at pretreatment and posttreatment.
Results: Overall, 140 children and adolescents with ADHD were enrolled and screened for chronic rhinitis. Fifty-four children and adolescents with positive screening results underwent the skin prick test and received rhinitis treatment. After 3 months of treatment, inattentive, hyperactive/impulsive, and total ADHD symptom scores were significantly decreased as reported by parents ( p = 0.031 to <0.001) and teachers ( p = 0.001 to <0.001) compared with those before treatment. A subgroup analysis also showed improvement in ADHD symptoms as reported by parents and teachers in the allergic and nonallergic rhinitis groups. Pearson's correlation coefficient analyses showed positive correlations between improvement in the ADHD symptom scores reported by parents and improvement in the quality of life related to sleep problems from the OSA-18 questionnaire (r = 0.377-0.387).
Conclusion: Treating chronic rhinitis can improve ADHD symptoms in children and adolescents with ADHD. Pediatricians should be aware of and treat chronic rhinitis to maximize ADHD symptom control.
