Brain wave test could spot Alzheimer's early
NCT ID NCT04954183
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a simple, non-invasive brain wave test (EEG) can help diagnose Alzheimer's disease at different stages. Researchers collected EEG data from 29 people, including those with mild cognitive impairment, Alzheimer's at various stages, dementia with Lewy bodies, and healthy volunteers. The goal was to see if brain wave patterns differ between these groups, which could lead to a cheaper and more accessible diagnostic tool.
What this could mean
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 lead to a non-invasive, low-cost EEG-based tool to help diagnose Alzheimer's disease earlier and more accurately.
- What could go wrong
- This is a very small, early feasibility study with only 29 participants. It is designed to collect data, not to prove a diagnostic test works. Many more studies are needed before this could be used in clinics.
