Neuropsychological approach to subjective cognitive complaints in cognitively unimpaired older people: A systematic review

Abstract

Objective: A systemized approach to subjective cognitive complaints (SCCs) in elderly people is needed owing to the high prevalence of such complaints and their impact on the psychosocial well-being of those affected. The aim of this study was to carry out a systematic review of the characteristics and effectiveness of intervention programmes that use a neuropsychological approach to target SCCs in cognitively unimpaired older people and that are tested in randomized controlled trials. Methods: The search included a time-unlimited query of Scopus, PsycInfo and Medline, yielding 215 articles, of which only 7 met the inclusion/exclusion criteria. Results: The number of intervention programmes was very limited (11 interventions), but diverse, with cognitive stimulation, physical exercise, psychoeducation and cognitive restructuring all used to address SCCs. Conclusions: Interventions including only cognitive stimulation were not effective in reducing SCCs, but interventions including cognitive stimulation and psychoeducation, physical exercise, and group sessions and discussions reinforced by the therapist were effective.
