The Claim
There is no statistically significant difference in the DTI-ALPS asymmetry index between individuals with ME/CFS and healthy controls.
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.
The difference in glymphatic system asymmetry between people with ME/CFS and healthy individuals is not statistically detectable.
See the scientific wording
No significant difference in DTI-ALPS asymmetry index was found between individuals with ME/CFS and healthy controls (p = 0.357), suggesting that while right-hemisphere glymphatic function is reduced in ME/CFS, the degree of asymmetry relative to controls is not statistically distinct.
In people with ME/CFS, the brain's waste-clearance system works less effectively on the right side than on the left, but this imbalance is not stronger than what occurs in healthy people. The right side clears fluid and toxins more slowly due to reduced flow in the channels around blood vessels, leading to buildup of waste and inflammation on that side, yet the difference between left and right remains similar to that seen in individuals without ME/CFS.
What the research says
1 studyThe study found that while the right side of the brain clears waste less effectively in people with ME/CFS, the difference between the left and right sides isn’t any bigger than in healthy people — so this imbalance isn’t something special to ME/CFS.
