Can brain training smartphone apps and computer games really help you stay sharp?

A large number of apps and computer programs claim to help keep the mind sharp and improve memory. Since there is limited evidence that these programs bring cognitive benefits, be skeptical of these claims and choose the ones that you enjoy. Meanwhile, practice proven brain-protecting strategies such as staying physically active, eating a healthy diet, socializing, and avoiding brain-harming habits such as drinking excess alcohol, getting too little sleep, and using illegal drugs.
