A specific regimen of computer-based brain exercises focused on visual processing speed may lower the long-term risk of receiving a dementia diagnosis. A new analysis of data spanning two decades suggests that older adults who engaged in this adaptive training, provided they participated in follow-up sessions, were approximately 25 percent less likely to be diagnosed with dementia compared to a control group. These results were published in the journal Alzheimer’s & Dementia: Translational Research & Clinical Interventions. The search for effective ways to prevent or delay Alzheimer’s disease and related dementias is a primary focus of modern medical research. While physical exercise and diet are frequently cited as potential protective factors, the role of specific cognitive training remains a subject of intense debate. Many commercial products promise to sharpen the mind, yet scientific evidence supporting their ability to prevent disease has been inconsistent. To address this uncertainty, researchers revisited data from a gold-standard clinical trial to see if specific interventions had lasting effects on brain health. The research was led by Norma B. Coe, a …
