Griffith University Ties ME/CFS to Right-Brain Glymphatic Impairment in 31 Patients
3 articles · Updated · ScienceAlert · Jul 9
Summary
MRI scans of 31 ME/CFS patients showed reduced glymphatic function in the brain’s right hemisphere versus 27 healthy controls, marking the first study to link the brain’s waste-clearance system to the illness.
The Griffith team used a non-invasive MRI method that estimates how cerebrospinal fluid diffuses around small blood vessels, offering a possible mechanism for the inflammation and neurological symptoms reported in ME/CFS.
Worse sleep problems and concentration deficits tracked with greater right-hemisphere dysfunction, reinforcing researchers’ view that disrupted sleep-related brain clearance may contribute to “brain fog” and fatigue.
Published in Frontiers in Neuroscience, the preliminary study cannot explain why the effect appears only on the right side, but researchers say it could support future non-invasive diagnosis and treatment research.
Why might chronic fatigue selectively impair the waste disposal system in only the brain's right hemisphere?
This discovery links a brain 'waste system' to chronic fatigue. Could therapies that flush the brain become a future cure?
Could a 'clogged' brain drainage system be the hidden cause of chronic fatigue and its debilitating brain fog?
Direct Imaging Reveals Impaired Glymphatic Brain Waste Clearance in ME/CFS: DTI-ALPS as a Breakthrough Diagnostic Biomarker
Overview
A groundbreaking study by Griffith University, published in June 2026, has provided the first direct imaging evidence of impaired brain waste clearance in people with ME/CFS. Using a non-invasive technique called DTI-ALPS, researchers were able to measure glymphatic flow—the brain’s system for removing toxins during sleep. The study found that this waste clearance system is significantly disrupted in ME/CFS patients, offering a clear biological explanation for their symptoms. This breakthrough not only advances understanding of ME/CFS but also opens the door to objective diagnosis and new treatment possibilities.
