According to a study conducted by the BBC brain training don't train your brain.The investigation saw a sample of 11,430 people play games such as
Dr. Kawashima's Brain Training for ten minutes a day, three times a week over a six-week course. The aim was to see if it provided any positive benefits to mental cognition. At least this was more intensive than
the last test we saw.
The result was that, while players got better at the games themselves, they "gained nothing in terms of general reasoning, memory, planning or visuospatial abilities."
Nintendo defended itself by releasing a statement that said that it never claimed such games to be scientifically proven to improve mental fitness. The company said that the
Brain Training games provide "fun challenges incorporating simple arithmetic, memorization and reading. In this way it is like a workout for the brain and the challenges in the game can help stimulate the player's brain."
Rebecca Wood of the Alzheimer's Research Trust told the BBC that more research was required to confirm whether the games had any beneficial effect on cognition over a long-term period.
