Abstract

The present study was conducted to determine whether anxiety among community-dwelling elders is associated with cognitive decline over a period of one year as well as to verify whether there are sex differences in the association between anxiety and cognitive decline. Participants (n=1942) were community-dwelling adults aged 65-96 years assessed at study entry (T0) and one year later (T1). Anxiety was identified with a semi-structured interview and cognitive functioning was assessed using the Mini-Mental State Examination. Results revealed that the presence of a clinically significant anxiety disorder did not predict cognitive decline in men and women. Subclinical anxiety symptoms predicted cognitive decline in women only. Moreover, for men, the presence of symptoms from at least two anxiety disorders predicted cognitive decline. For women, cognitive decline was predicted by the presence of symptoms from one anxiety disorder only. Overall, the results illustrate the role of anxiety in cognitive decline in community-dwelling older adults.
