Cognitive interventions in mature and older adults, benefits for psychological well-being and quality of life: a systematic review study

Few recently published studies investigating the benefits of educational and cognitive interventions on quality of life (QoL), psychological well-being, and depressive symptoms are available. The aim of this study was to investigate the effects of educational and cognitive interventions on psychological well-being, QoL, and mood in mature and older adults without dementia and/or with mild cognitive impairment (MCI). The systematic review took place from September to October 2020 and the following databases were used to select the studies: SciELO, LILACS, PubMed, and Medline. The search terms used were idos* AND "treino cognitivo" AND "bem-estar psicológico" AND "qualidade de vida" and their corresponding translations in English and Spanish. Of the 241 articles retrieved, 26 primary studies were included in the review. Of these, 18 showed improvement in QoL, psychological well-being, or cognition. The studies reported beneficial effects of educational and cognitive interventions for QoL, psychological well-being, and depressive symptoms of mature and older adults without dementia or depression.
