Many recent studies had already suggested a role of sodium accumulation in brain tissue loss in MS. Previous work had also shown significant sodium accumulation in regions where there was no apparent cell death, suggesting that cell-death does not drive measured sodium concentrations. What's cool about this result is 1) that sodium measurements from the brain are better indicators of cognitive defects than actual death of brain cells. 2) Abnormal sodium accumulation occurred in neocortex, which is the first place you'd suspect cognitive impairment to originate. That's a correlation across patients, and brain areas, suggesting at the least that NaMRI is a good tool for early MS detection. I doubt it's dietary sodium. Likely, sodium accumulation occurs when normal processes are disrupted. I wouldn't expect increased sodium in your diet to lead directly to increased sodium in selective areas of the brain (could be wrong here).
