John DenBoer and his grandmother.

How Smart Brain Aging hopes to hold off dementia with brain training games

My 85-year-old mother has dementia, a memory loss disease that affects about 60 million people in the U.S. And so I can relate to the challenges of fighting the disease that John DenBoer has dedicated his life to fighting. He has started a company called Smart Brain Aging that has created brain-training exercises that he hopes can hold off the onset of dementia, which has seven different stages.

DenBoer’s own grandmother suffered from dementia when he was going to medical school, and it became his obsession to treat it. He became a clinical neuropsychologist and researcher in hopes of treating dementia. And his research shows that cognitive and functional impairment in early stage dementia can be slowed by the right kind of cognitive exercise. His company has created a cognitive training program, an iOS app called Brain U Online, that prevents memory loss and mitigates functional decline.
