Dimensions of cognitive reserve and their predictive power of cognitive performance and decline in the elderly.

ABSTRACT:

Background

The relative importance of different components of cognitive reserve (CR), as well as their differences by gender, are poorly established.

Objective

To explore several dimensions of CR, their differences by gender, and their effects on cognitive performance and trajectory in a cohort of older people without relevant psychiatric, neurologic, or systemic conditions.

Methods

Twenty-one variables related to the education, occupation, social activities, and life habits of 1,093 home-dwelling and cognitively healthy individuals, between 68 and 86 years old, were explored using factorial analyses to delineate several dimensions of CR. These dimensions were contrasted with baseline cognitive performance, follow-up over 5 years of participants' cognitive trajectory,
