FLG and Alzheimer disease: We performed a single‐centre, prospective, parallel‐group, randomised, pragmatic study to compare the incidence of moderate or severe AD in a cohort of at‐risk infants of predominantly Asian descent, in the first year of life, with at least 2 first‐degree family members with atopy, commenced within the first 2 weeks of life on a ceramide and filaggrin‐product containing moisturiser, to a control group of infants not treated with the same moisturiser.
