A recent study published in Nature found that our brains may go through three bursts of accelerated ageing, with peaks in protein levels occurring at ages 57, 70, and 78. The research, based on nearly 11,000 MRI scans and blood samples, suggests a connection between specific proteins and predicted brain ageing, particularly pointing to the protein brevican. While testing blood protein levels at these ages could potentially be a protective factor against conditions like dementia, it is not a definitive diagnosis. Further research is needed, but the study highlights the importance of monitoring brain health as we age.
