What diabetes and Alzheimer’s have in common

Type two diabetes is associated with high levels of tau protein in the cerebral spinal fluid, suggesting the protein may be key to the connection between T2DM and Alzheimer’s disease, an Australian study reveals.

Levels of total and phosphorylated tau were higher in 124 people with type 2 diabetes mellitus (T2DM) than in 692 patients without diabetes, report the study authors, led by Associate Professor Velandai Srikanth, of Monash University.
