IntroductionBrain health has garnered increasing attention as a requisite condition for healthy aging. The rapid growth in mobile health and increasing smartphone ownership among older adults has paved the way for smartphones to be utilized as effective tools for improving mental fitness.ObjectivesThere are few studies that have explored the efficacy of smartphone-based cognitive training. The present study examined the memory-enhancing effects of smartphone-based memory training for older adults.AimsWe explored whether newly developed application “Smartphone-based brain Anti-aging and memory Reinforcement Training (SMART)” improved memory performance in older adults with subjective memory complaints.MethodsA total of 53 adults (mean age: 59.3 years) were randomised into either one of two smartphone-based intervention groups (SMART vs. Fit Brains®) or a wait-list group. Participants in the intervention groups underwent 15–20 minutes of training per day, five days per week for 8 weeks. We used objective cognitive measures to evaluate changes with respect to four domains: attention, memory, working memory (WM), and executive function (inhibition, fluency, etc.). In addition, we included self-report questionnaires to assess levels of subjective memory complaints.ResultsThe performance on WM test increased significantly in the SMART group (t[17] = 6.27, P < 0.0001) but not in the control groups. Self-reports of memory contentment, however, increased in the Fit Brains® group only (t[18] = 2.12, P = 0.048).ConclusionsUse of an 8-week smartphone-based memory training program may improve working memory function in older adults. However, objective improvement in performance does not necessarily lead to decreased subjective memory complaints.Disclosure of interestThe authors have not supplied their declaration of competing interest.
