Ward ME, et al. - This study entailed an inquiry of the tie-up between visual contrast sensitivity (a functional measure of low contrast vision) and poor cognitive performance or dementia in a population-based cohort with final adjudication of mild cognitive impairment (MCI)/dementia. Data shed light on the connection between reduced contrast sensitivity with a greater risk of MCI/dementia among older women. Visual system neurodegeneration or dysfunction possibly appeared to parallel or precede dementia-related cortical or subcortical degeneration. Moreover, it was illustrated that contrast sensitivity testing could be beneficial for detecting the aging adults at high risk for dementia.
