Visual issues may be an early indicator of cognitive decline as the
toxic amyloid plaques associated with Alzheimer's disease may first
affect areas of the brain associated with vision, with parts of the
brain associated with memory becoming damaged as the disease
progresses. So vision tests may find deficits before memory tests do.

Another early sign of Alzheimer's is a deficit in the "inhibitory
control" of eye movements, where distracting stimuli seem to hold
attention more readily. People with Alzheimer's seem to have an issue
ignoring distracting stimuli, which may show up as
eye-movement-control issues.
