   Proposal Description:
   Aim 1: To test the hypothesis that visual impairment is associated with cognitive  decline and to examine the effect of visual impairments on the pace of the cognitive decline.     Aim 2: To examine whether visual impairment influences the cognitive functioning of older adults through the pathway of brain neurodegeneration.   Whether visual impairment is associated with brain structure change is unknown.   We hypothesized that visual impairment is associated with brain structure change  and greater brain volumetric declines in older adults.
