Brain-training games do not improve overall brain power, a scientific study launched by the BBC suggests.
The largest investigation of its kind followed 11,430 people over six weeks to see what effect, if any, playing brain-training computer games would have.
The results, published in the journal Nature, showed that while players got progressively better at the games, they did not improve brain function beyond the tasks that were actually being trained to do.
