New spinal fluid test aims to solve dementia misdiagnosis puzzle
NCT ID NCT07166744
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study will test whether measuring a specific abnormal protein (alpha-synuclein) in spinal fluid can reliably distinguish dementia with Lewy bodies (DLB) from Alzheimer's disease. Researchers will collect samples and perform cognitive tests on 286 older adults with suspected DLB or Alzheimer's. A better diagnostic test could prevent dangerous medication errors in DLB patients.

What this could lead to
If successful, this could lead to a reliable diagnostic test for dementia with Lewy bodies, reducing misdiagnosis and preventing harmful treatments.
What could go wrong
This is an observational study, not a treatment trial. The test may not prove accurate enough in real-world settings, and results may not change clinical practice quickly.
