Abstract

Performance on neuropsychological tests is affected by age and education, which makes the early detection of cognitive impairment difficult when assessing individuals of varying levels of education. We examined the effects of age, education, and gender on three memory indexes of the Wechsler Memory Scale-III, Delayed Memory, Working Memory and the difference between Working-Delayed Memory in a sample of patients with amnestic Mild Cognitive Impairment, patients with mild probable Alzheimer's disease, and a nondemented elderly comparison group. Whereas Delayed and Working Memory scores were affected by participant type, age, and education, the Working-Delayed Memory difference score was affected by participant type, only. Our preliminary conclusions, pending replication of the findings with a larger sample, are that working-delayed memory difference was sensitive to early memory decline without being affected by age and education.

Alzheimer's Disease: Early Markers

Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive cognitive and behavioral decline. Targeting markers in the earliest stages of the disease may mitigate the progression of AD. This feed focuses on early diagnosis and markers, as well as environmental, pharmacological, and drug-response biomarkers associated with this disease.
