Identifying Blood-Protein Imbalance as a Marker for Future Dementia Risk

A study has identified proteins that are linked to the development of dementia if their levels are unbalanced during middle age. The researchers found 32 proteins that, if dysregulated in people aged 45 to 60, were strongly associated with an elevated chance of developing dementia in later life. These proteins have functions unrelated to the brain, suggesting that mechanisms below the neck could also play a role. The findings could contribute to the development of new diagnostic tests and treatments for dementia-causing diseases.
