Intraindividual cognitive variability has no effect on white matter lesions in humans (all p's > .05).
“IIV showed no significant association with WMLs, neither within nor across the domains examined (all p’s>.05).”

Intraindividual cognitive variability raises the risk of cognitive impairment in humans (OR 0.94, 95% CI 0.92–0.96).
“for every one‐unit increase in CoV, the odds of developing cognitive impairment decreased by 6% (OR 0.94, CI95% 0.92 – 0.96)”
