Our daily life is based on being able to remember information over long intervals of time. This week we publish an article in PNAS, which shows a possible link between abnormal brainwaves in patients with Alzheimer’s disease and a decline in cognitive function.

We measured the brainwaves of patients with Alzheimer’s disease and healthy subjects using a non-invasive method called magnetoencephalography (MEG – a method almost similar to electroencephalography (EEG)) . We found that the brainwaves in patients with Alzheimer’s disease were less stable and had weaker correlations over time compared to healthy subjects.
Our results shows that (1) non-invasively measured biomarkers of abnormal brainwave can identify certain aspects of Alzheimer’s disease, and (2) brainwaves might give us a better understanding of Alzheimer’s disease and brain function in general.
