Description

Kaj Blennow studies a blood marker for Alzheimer's disease in a 2025 paper. The marker, a changed form of tau protein, is read as a ratio against its unchanged form in some tests. That ratio was hoped to sharpen detection of Alzheimer's-type change.

Blennow shows that fast brain cell loss and sudden injury can skew the ratio in both spinal fluid and blood. The unchanged form rises with general cell damage, dragging the ratio with it. Data came from large groups with Alzheimer's, a prion disease, and acute injury, read by two methods. Clinics should read the ratio with care when other brain harm is present.
