The cognitive intervention for the ageing population is growing rapidly. This review aimed to explore the impact of cognitive intervention on the cognitive abilities among adults over 50 with mild cognitive impairment (MCI) in Asia. Articles on randomised controlled trials (RCT) studies published between 2010 and December 2020 in PubMed, Science Direct, Web of Science, and Scopus databases were searched. A total of 13 studies were included in this review for further analysis. The results showed that cognitive training can be effective in improving the cognitive function in adults with MCI in various aspects, including memory, attention, executive functioning, reducing subjective memory complaints, and improving daily living skills. The findings indicated that different modalities of cognitive intervention, namely single-domain, multi-domain, and multimodal modalities could be a promising intervention in improving the overall cognitive abilities of adults with MCI in Asia. The single-domain cognitive intervention was influenced by the far transfer effect that improved other untrained cognitive areas. Both multi-domain and multimodal cognitive interventions showed improvement in the global cognitive function and transfer effect on the non-cognitive areas such as daily activities and mood. Future review could explore the impact of intervention duration on cognitive abilities and the transfer effect for each modality to understand the ideal intervention package for adults over 50 with MCI in Asia.

Background: The effects of aging and its associated cognitive decline is particularly acute in Asia given the exponential growth of older adults as a proportion of the population as a whole. Many structured cognitive interventions have been proposed to prevent the cognitive decline typically seen in older age, but their utility as a viable means of achieving these goals is questionable., Objectives: To summarize and synthesize evidence on the utility and methodological quality of cognitive-based interventions on cognitive performance and associated secondary outcomes among healthy older adults in Asia, as well as novel, culture-specific components of cognitive interventions across the region., Data Sources: The PubMed/Medline, Web of Science, Scopus, and ScienceDirect databases were searched through May 2020., Eligibility: Studies including individuals aged 60 years and above, who had no previous history of physical and/or mental illness. Few restrictions placed on intervention design, duration and mode of delivery, provided that participants were randomized to study conditions, and intervention included components addressing at least one cognitive domain., Results: A total of 17 studies from six countries met the eligibility criteria and were included in the final review. Evidence from those studies indicated that cognitive interventions may be most effective when the design and aims were directed towards improvement in specific cognitive domains, but evidence regarding long-term effectiveness in preventing progression to clinical-level cognitive deficits is still unclear. Several studies highlighted culture-specific activities as components of their interventions, though these will need to be further outlined and standardized clearly in future research., (Copyright © 2021 Elsevier B.V.
