Circulating Protein Biomarkers Correlate with Future Risk of Dementia

Researchers here demonstrate a predictive biomarker panel for Alzheimer's disease risk based on protein levels assessed in a blood sample. This is a one of a number of similar tests developed in recent years. The question is what one might do given a measurement that suggests high risk of Alzheimer's disease. At present, the only option is to generally improve lifestyle choices, but Alzheimer's is not as correlated with lifestyle factors as is the case for, say, type 2 diabetes. Based on the suggestion that senescent cells are important to neurodegeneration, one might take senolytic drugs intermittently, a few times a year at most. Based on the evidence for persistent viral infection to be important to the development of Alzheimer's disease, one might choose to take antiviral drugs. Other options are thin on the ground at present. Scientists used the largest cohort of blood proteomics and dementia to date, including blood samples from 52,645 healthy participants recruited from UK Biobank - a population-based study cohort. Blood samples collected between 2006 and 2010 were frozen and then analysed 10-15 years later by the research team who analysed them between April 2021 and February 2022. Until March 2023, a total of 1,417 participants went on to develop dementia - and these people's blood showed dysregulation of protein biomarkers. Of 1,463 proteins analysed, aided by with a type of artificial intelligence known as machine learning, 11 proteins were identifi...
