The discovery is disconcerting and counterintuitive, to say the least. Newborns have blood levels of a typical Alzheimer's biomarker, called p-tau27, three times higher than those of older adults with the disease, according to a study published in Brain Communications.
A few months later, these levels returned to normal. Faced with this rather enigmatic phenomenon, a team is working to understand what this biomarker might be used for early in life and how babies manage to get rid of it. The team hopes to find a new way to combat the development of Alzheimer's disease in adults.
