Dementias and Mild Cognitive Impairment in Adults

The Little Black Book of Neuropsychology

Abstract

Dementia does not describe a specific disease entity, but rather describes a clinical syndrome characterized by a loss of previously acquired cognitive functions that adversely affects an individual’s ability to complete day to day activities. The decline in cognitive functioning is greater than what occurs during the normal aging process. This chapter will review prominent definitions of dementia and a number of the etiologies of this syndrome. The prodromal phase between dementia and normal aging, Mild Cognitive Impairment (MCI), is reviewed later in this chapter. Readers interested in a more detailed review of dementia syndromes and conditions presenting as dementia are referred to Mendez and Cummings (Dementia: a clinical approach, 3rd edn, Butterworth Heinemann, Philadelphia, 2003).
