When both groups had cognitive testing, they found both posted nearly identical rates of improvement in various measures. Suggesting the specially designed games were no better than video games in general.
Important to note of course, that this test was in young, healthy volunteers – not the intended audience for brain training games.
But it goes to show how much more we need to learn before we can find an antidote to dementia.
