The Claim
In individuals with ME/CFS, the right hemisphere exhibits significantly lower DTI-ALPS indices (mean 1.41 ± 0.097) compared to the left hemisphere (mean 1.47 ± 0.11, p = 0.012), indicating lateralized glymphatic dysfunction that is absent in healthy controls.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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, brain imaging shows reduced glymphatic system activity in the right hemisphere compared to the left hemisphere, a difference not seen in healthy individuals.
See the scientific wording
In individuals with ME/CFS, the right hemisphere shows significantly lower DTI-ALPS indices (mean 1.41 ± 0.097) than the left hemisphere (mean 1.47 ± 0.11, p = 0.012), indicating lateralized glymphatic dysfunction that is not observed in healthy controls.
In people with ME/CFS, fluid flow around blood vessels in the right side of the brain is reduced, causing waste products to build up more than on the left side. This buildup triggers inflammation in the right hemisphere, which disrupts brain function and causes symptoms like fatigue and trouble concentrating.
What the research says
1 studyThe study found that people with ME/CFS have lower brain waste-cleaning scores on the right side, but so do healthy people — the difference between right and left sides is the same in both groups. So, the asymmetry claimed in the statement doesn’t actually exist in this data.
