The increasing global aging population and the rising incidence of dementia create urgent demands for medical professionals. Innovation in medical technology is driving novel approaches to facilitate early diagnosis, rehabilitation, treatment, and care. Researchers worldwide are increasingly exploring the potential of mobile applications to support effective cognitive training for older adults and individuals living with dementia. Cognitively stimulating activities have consistently demonstrated a positive influence on cognitive functions such as processing speed, memory, reasoning, and verbal abilities. These activities are among the non-pharmacological approaches recommended for dementia care. Consequently, engaging in cognitively stimulating activities could benefit older adults by decreasing the risk of developing neurodegenerative conditions or helping to halt the progression of mild cognitive impairment in some individuals. The increasing use of mobile devices across all demographics, including 61% of adults aged 65+ according to a 2022 Pew Research Center study in the United States (Faverio, 2023), makes mobile platforms a promising vehicle to expand access, ease, and usability in cognitive training. This review aims to summarise findings from scientific literature on existing mobile applications designed to promote cognitive training and their potential to support cognition in older adults. The review presents examples of commercially available mobile games for cognitive training and exercise, discussing their potential advantages and disadvantages in usability for cognitive stimulation therapy in older adults.
