Myelin Damage Triggers Abnormal Brain Rhythms During Sleep

Demyelination triggers abnormal, epileptiform electrical spikes coupled with Stage 2 NREM sleep spindles and induces a severe slowing of rhythmic REM sleep oscillations, establishing overnight sleep recordings as a non-invasive biomarker for tracking MS and Alzheimer's progression.

This shows a person sleeping, surrounded by sound waves.
