    Abstract:
    BACKGROUND: Previous studies have assessed the relationship between subjective cognitive complaints and objective impairment. While some of them found that cognitive complaints were explained by affective disorders, other researches found a relationship between cognitive complaints and neuropsychological performance. Most of them focused on memory functioning. However, elderly normal adults also display a decline in executive functions. This study aimed to assess the relationship between cognitive complaints, objective memory and executive performance and affective disorders. METHODS: This study was carried out with 937 community-dwelling elderly individuals recruited from the electoral list of the city of Saint-Etienne, France. Cognitive complaints were assessed using the MacNair scale. Cognitive performances were measured via a large battery of memory and executive-performance tests chosen for their capacity to detect subtle cognitive impairment. Anxiety and depressive symptoms were assessed using scales devised by Pichot and Goldberg. RESULTS: Cognitive complaints were associated with lower scores on verbal-memory tests and several executive-performance tests. Moreover, affective disorders were related to some of the executive-performance test scores, but they were not related to scores on the Free and Cued Selective Reminding Test, Digit Symbol Substitution Test and Trail Making B scores. CONCLUSIONS: Cognitive complaints of the elderly can reflect objective memory and executive-performance impairments, independent of affective disorders. Cognitive complaints should be assessed using both memory and executive-performance tests.
