Summary

Story summary

Brown University researchers identified a brain-based biomarker using magnetoencephalography that may predict Alzheimer's disease progression from mild cognitive impairment.
The study was published in Imaging Neuroscience and marks the first time this brain activity has been linked to Alzheimer's.
In 85 patients, those who later developed Alzheimer's showed lower beta wave rates, shorter durations, and weaker power.
