If keeping the brain in shape was as straightforward as lifting weights, everyone would want to purchase the ideal piece of cognitive drift hunters training equipment. However, creating activities to counteract the cognitive impacts of aging is difficult. A new computer game developed by neuroscientists shows potential for correcting certain indicators of deterioration. Now, the researchers want to demonstrate that video game training may be more than just the newest exercise trend.

Games developed to keep the brain healthy as we age have found a receptive audience. "Many, many people have gotten into the business," says neuropsychologist Glenn Smith from the Mayo Clinic in Rochester, Minnesota. The brain seems to be capable of altering structure and learning new abilities over the course of a lifetime. However, not all products on the market are based on scientific understanding of the aging brain, and their capacity to create substantial, long-term changes has yet to be shown, according to Smith, who researches games as a therapy for early indications of dementia. "There's an awful lot of skepticism out there," he acknowledges.

The crux of the question is whether playing a video game may improve abilities that are valuable outside of the computer. According to Smith, early studies demonstrated that humans may improve on computerized memory and speed tests in the lab. However, it is unclear if these advantages will transfer into daily life. A current trend emphasizes games that address the underlying issue—the reduction in people's capacity to recall and respond as they age.
