This chapter considers cognitive functioning in persons age 65 or older. Persons within this age group commonly report difficulty with memory and other cognitive abilities compared to an earlier period. These perceptions may contribute to concern about Alzheimer’s disease (AD) and other dementing illnesses. In view of the prevalence of AD and other conditions that affect cognition in this age group (e.g., Parkinson’s disease, stroke), such concern is understandable. Indeed, impaired cognitive function in older persons is associated with loss of independence, increased morbidity and mortality, and reduced quality of life. Not surprisingly, therefore, considerable scientific effort has been expended in attempts to understand age-related cognitive decline, its neural bases, and factors which may modify or delay it.
