Abstract
A new research from Western University in Ontario, Canada showed brain training apps don’t make any difference between the brain trainers and non-brain trainers.
They checked 12 cognitive tests for the participants. The results unaffected any conditions that are like participants' ages or how long brain training was used.

Are you surprised by the results of this study?
I was surprised by it. Because such brain training apps likely have a good effect on our brain. But the research suggests such time when we use brain training apps is a waste.
It is ok using the apps to just enjoy, but when we want to improve our brain function, we have to check the evidence against the ways of training.
