Guo MMH, Wang LJ, Hsu TY, et al. - Given a link between childhood allergic diseases and symptoms of attention-deficit hyperactivity disorder, but the existing lack of clarity regarding the temporal link between these conditions, researchers performed this inquiry among 97 children, to address this topic. Clinical tests and blood samples for total and specific IgE were obtained at 6 and 12 years old. They identified higher inattention score at 12 years old in relation to allergic rhinitis at 6 years old, after accounting for the impact of confounding variables. Also, they noted a correlation between higher specific IgE levels for peanuts at 6 years of age and higher hyperactivity/impulsivity scores, as well as the correlation between higher specific IgE for peanuts at 12 years of age and higher opposition/defiance scores at 12 years old in the final linear regression models. Overall, it was inferred that more symptoms of attention-deficit hyperactivity and oppositional defiant disorder in adolescence may be seen in relation to allergic rhinitis and peanut sensitization in childhood.
