The Claim
Increased atrophy of the medial temporal lobe, as measured by MRI visual rating scale, is associated with worse cognitive performance on the Montreal Cognitive Assessment, Mini-Mental State Examination, and Frontal Assessment Battery in patients with progressive supranuclear palsy and corticobasal syndrome.
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 patients with progressive supranuclear palsy and corticobasal syndrome, greater shrinkage of the medial temporal lobe observed on MRI scans is linked to lower scores on tests of memory, attention, and executive function.

Unstable blood sugar levels damage blood vessels in the brain, causing reduced blood flow to the memory center, which kills brain cells and shrinks the area. At the same time, low insulin levels in the brain stop it from protecting neurons and keeping brain chemicals balanced, making memory and thinking worse.
What the research says
1 studyIn people with these rare brain diseases, the more the memory part of the brain shrinks, the worse they do on memory and thinking tests—exactly what the claim says.
