A recent brief review by Jane Brodie points to work showing a small effect of cognitive training programs engaging memory, reasoning, or speed of processing. After 10 years 60% of those in the training programs, compared with 50 percent of the controls, had maintained or improved their ability to perform activities of daily living. Reasoning and speed, but not memory, training resulted in improved targeted cognitive abilities for 10 years. The article also contains a brief video demonstrating the NeuroRacer program developed by Gazzaley and colleagues. The article points out that very few of the potions and gizmos on the market "...have been proven to have a meaningful, sustainable benefit beyond lining the pockets of their sellers. Before you invest in them, you’d be wise to look for well-designed, placebo-controlled studies that attest to their ability to promote a youthful memory and other cognitive functions."
