A previous study indicated that atopic dermatitis (AD) was associated with better cognitive function in males during late adolescence. This association was examined among 2 021 369 males who had a medical examination and cognitive function testing during a military conscription assessment in late adolescence in Sweden. Sibling-comparison analysis to tackle confounding indicated that AD is associated with poorer cognitive function, suggesting AD in childhood is detrimental for the development of cognitive function.
