Information Technology (IT) plays a vital role in promoting sustainability and enabling independent living. People with cognitive disabilities face numerous challenges in their daily lives, such as social interactions, learning new things, and improving specific abilities. A variety of therapies and treatments have been introduced to help address these challenges. Recently, computer-assisted therapeutic procedures, treatment procedures, and assistive systems have emerged as beneficial tools to improve the lives of people with cognitive disabilities. Advances in technology have made it possible to develop effective applications specifically designed for this group of individuals. The objective of this paper is to identify potential applications of these developed solutions for people with cognitive disabilities, evaluate their effectiveness, strengths, and limitations, and understand their contribution in addressing various difficulties due to cognitive impairments. To achieve this goal, we reviewed 23 studies that demonstrate several applications developed for people with cognitive disabilities to address their unique issues. Our investigation indicates that the developed applications hold promise, although a few issues with cost-effectiveness, device transparency, and specific disability dependency may limit their effectiveness. Hence, this paper aims to shed light on these innovative applications, their implications, and their role in aiding users in tackling their specific challenges.
