Study questions benefits of computerized brain exercise
The short-term benefits of computerized cognitive training (CCT) on healthy older adults is being questioned after researchers reviewed and analyzed 51 previous studies involving 4,885 individuals.
The current study, published in PLOS Medicine, was conducted by researchers at the University of Sydney in Australia. The study authors found that CCT was only "modestly effective" in improving cognitive performance in healthy older adults and showed no significant effects on executive functions, such as planning and judgement or attention spans.
The study also found that training more than three times per week was counterproductive and that training at home with no supervision was considerably less effective than in a supervised group environment.
Since the study only looked at short-term gains, the researchers admit that longer-term outcomes were not evaluated.
