ABSTRACT
This chapter presents Alzheimer's disease (AD) as a simultaneous visuoperceptual and cognitive illness, with a view to educating care-givers about the types of visual deficits and resultant difficulties that persons can experience. Typical visuo-cognitive errors made by persons with AD throughout the illness process are presented to illustrate the ever-changing nature of the visual world to a person with AD. This chapter also provides possible ways of making care environment adaptations to aid in the perception of key visual information.
