The brain’s waste clearance system is impaired in people living with Myalgic Encephalomyelitis\/Chronic Fatigue Syndrome (ME\/CFS) which can lead to various symptoms including brain fog, Griffith University researchers have discovered.<\/p>\n
The research demonstrates, for the first time, the impact ME\/CFS has on glymphatic function which is responsible for clearing the brain of metabolic waste products and is mostly active during sleep and disengaged while a person is awake.<\/p>\n
Lead author Dr Kiran Thapaliya from Griffith’s National Centre for Neuroimmunology and Emerging Diseases (NCNED) said when the brain’s waste clearance system did not work properly, harmful waste could build up causing neuroinflammation.<\/p>\n
“This study is the first to demonstrate impaired glymphatic function\u00a0in ME\/CFS using MRI, providing a mechanistic explanation for the inflammatory changes reported by other Australian and international teams,” he said.<\/p>\n
“This suggests that dysfunction in the brain’s natural cleaning system may be a key driver of this condition.”<\/p>\n
Professor Sonya Marshall-Gradisnik, NCNED Director, said not only did reduced glymphatic function cause brain fog, but also caused sleep disturbance.<\/p>\n

The study found worse sleep is associated with poor brain waste clearance, reinforcing the notion that sleep plays a critical role in maintaining brain health,” she said.<\/p>\n

We hope the results can pave the way for better diagnosis through the use of non-invasive procedures, and importantly, future treatment for patients.”<\/p>\n
