The Claim
In cognitively healthy adults, cortical thickness in speech motor regions is not significantly correlated with performance on standard cognitive tests after correcting for multiple comparisons.
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 adults without cognitive impairment, the thickness of brain regions involved in speech does not relate to scores on standard memory or thinking tests when accounting for statistical comparisons.
See the scientific wording
In cognitively healthy adults, cortical thickness in speech motor regions is not significantly correlated with performance on standard cognitive tests after correcting for multiple comparisons, suggesting these structural changes may reflect intrinsic aging rather than cognitive decline.
As people age, the outer layer of the brain in areas that control speech naturally becomes thinner, but this thinning does not affect how well the brain performs memory or attention tasks because these processes rely on different brain networks that remain structurally stable.
What the research says
1 studyThe study found that how thin the brain's speech areas get as people age doesn't tell us anything about how well someone remembers things or pays attention — so those changes are just part of normal aging, not signs of memory problems.
