Differences in the association between white matter hyperintensities and gait performance among older adults with and without cognitive impairment.

Our findings suggest that gait variability measures are more sensitive to subtle underlying neurological pathologies including WMHs in older adults. The cognitive-dependent differences found in the association between WMHs and gait performance suggests that the level of cognitive function interferes with the association between WMH and gait performance.
