One factor can age your brain faster – and you can do something about it

Researchers from Jilin University and China Medical University analyzed blood metabolites from 22,000 individuals and used machine learning on 37,500 UK Biobank participants to establish that elevated glucose levels are causally linked to accelerated brain aging and seven neurological disorders including Alzheimer's disease, Parkinson's disease, and dementia.

The precise biological mechanism remains unclear; lifestyle modifications (diet, exercise, weight management) can reduce but not eliminate genetic risk factors.
