American consumers spend close to $300 million a year on computer-based brain-training programs — "mind workouts" — from such companies as MindSparke, Lumosity and PositScience. For just a few minutes (and a few dollars) a day, these programs promise enhanced memory and improved productivity. But do they work?

It depends on whom you ask. Much of the excitement around brain training is due to the relatively recent discovery that the brain remains plastic — able to change structurally and functionally —throughout life. But while a plastic brain means cognitive improvement is possible, clinical studies examining computer-based brain-training programs offer mixed results. Some show slight improvement with regular use; others find they're nothing more than a fun distraction. The largest clinical trial to date, conducted by British researchers and published in the April 20, 2011, issue of Nature, found no significant cognitive gains after several weeks of brain training.
