Cognitive decline can also occur on the basis of factors not intrinsic to a particular subtype. The term ‘excess disability’ refers to a patient's functioning which declines more rapidly than is expected on the basis of cerebral pathology alone. This article discusses some relevant studies which show how the concept of ‘excess disability’ contributes to understanding the total disability of the Alzheimer's
