Blood test may spot Alzheimer's early?
NCT ID NCT00647478
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study measured levels of two substances (IGF-I and IGFBP-3) in the blood of 693 older adults: some with Alzheimer's disease, some with mild cognitive impairment, and some with normal memory. The goal was to see if these levels differ between groups and relate to thinking abilities. It is an observational study, not a treatment trial.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help identify biological markers for early detection or progression of Alzheimer's disease.
What could go wrong
This is an observational study, not a treatment trial. It only measures substances in the blood, so it cannot prove cause or lead directly to a therapy.
