Alzheimer's disease is a disorder which is typified by a deterioration in cognition and a range of behavioural problems which result in a loss of functional ability and often necessitate transfer to residential care. This article looks at a growing body of research which is revealing the presence of changes in vision, particularly contrast sensitivity and acuity. We discuss the possible pathological basis for such deficits, and examine the possibility that such changes in vision may impact on the behavioural and functional outcomes of the demented individual.
