A recent study suggests that playing video games for 30 minutes a day could help older adults gradually fight the effects of dementia by improving memory function. Games that involve a 3D environment with more advanced graphics appear to be more effective, as they offer more immersive gameplay. During the study, participants were asked to play video games for about 30 to 45 minutes per day over four weeks. Improvements in both cognition and memory skills were found in the group that played video games with 3D graphics. This could offer a simple and fun anti-dementia approach for older adults!
