Decline of cognitive capacity during aging

Abstract

Decline of cognitive capacity (DCC) is due to normal physiological aging processes or to pre-dementia stage. Epidemiological studies show that elderly with decline of cognitive capacity have higher risk to develop Alzheimer's disease (AD), especially those with episodic memory deficits. This review presents the most important diagnosis criteria, neuropathological and neuropsychological findings of decline of cognitive capacity during aging.
