Neurocognitive function in moderate–severe pediatric atopic dermatitis: A case–control study

Background/Objectives Epidemiological studies have shown an increased prevalence of attention deficit hyperactivity disorder (ADHD) in children with atopic dermatitis (AD), but many of the features of ADHD may occur as a result of the poor sleep and itch distraction associated with AD. Methods A case–control study was performed in children aged 6‐17 years with moderate/severe AD compared with age‐/sex‐matched healthy controls. Participants were screened for ADHD using Vanderbilt assessments. Results Seventeen patients with AD and 18 controls completed the study. Two children with AD (11.7%) and one control (5.56%) met screening criteria for ADHD via parent‐completed Vanderbilt assessments; AD patients were not significantly more likely to screen positive for ADHD (P = 0.47), or comorbid behavior disorders (P = 0.23). However, AD patients were more likely than controls to exhibit ADHD‐associated behaviors, most significantly inattention. Conclusions Our AD cohort did not have a significantly increased prevalence of ADHD. Certain neurocognitive symptoms are increased in children with moderate‐to‐severe AD compared to controls.
