Abstract
Data from a two-wave longitudinal study of an elderly community sample were used
to assess whether cognitive complaints either predict subsequent cognitive decline or reflect past
cognitive decline. Cognitive complaints and cognitive functioning were assessed on two occasions
three and a half years apart. Cognitive complaints at Wave 1 were found not to predict future
cognitive change on the Mini-Mental State Examination, an episodic memory test or a test of
mental speed. Similarly, cognitive complaints at Wave 2 were unrelated to past cognitive changes
on these tests after statistically controlling for the effects of anxiety and depression. Furthermore,
cognitive complaints did not predict either mortality (after controlling for anxiety and depression)
or future dementia. These results are evidence against the inclusion of cognitive complaints in
diagnostic criteria for proposed disorders such as age-associated memory impairment, mild
cognitive disorder and ageing-associated cognitive decline.
