The Claim
In individuals with ME/CFS, lower global DTI-ALPS indices are significantly associated with greater severity of sleep disturbance (r = −0.47, p = 0.013), indicating that reduced brain waste clearance correlates with worse sleep quality in this population.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people with ME/CFS, lower values of a brain imaging measure of waste clearance are linked to more severe sleep disturbances.

In individuals with ME/CFS, lower global DTI-ALPS indices are significantly associated with greater severity of sleep disturbance (r = −0.47, p = 0.013), suggesting that reduced brain waste clearance correlates with worse sleep quality in this population.
Poor sleep reduces the flow of fluid through the brain's waste-clearance system, causing toxins and inflammatory molecules to build up. This buildup irritates brain tissue, disrupts normal brain activity, and makes sleep even worse, creating a cycle that gets harder to break.
What the research says
1 studyIn people with ME/CFS, the study found that those with poorer brain cleaning during sleep also had worse sleep problems—like a clogged drain leading to more mess. The data shows a clear link between the two.
