Optimizing Vision May Slow Cognitive Decline, Helping Prevent Dementia

Vision impairment could prove to be a beneficial addition to the Lancet Commission’s life-course model of potentially modifiable dementia risk factors. The estimated population attributable fractions (PAFs) of dementia associated with vision impairment and other dementia risk factors (11 of those included in the Lancet Commission’s life-course model) were calculated to assess and strengthen an existing model of potentially modifiable dementia risk factors, say researchers of study published in JAMA Neurology.
