For a younger-working brain -Cognitive training

Researchers at the Center for BrainHealth at The University of Texas at Dallas say their research could provide new hope for extending our brain function as we age. In a randomized clinical study involving adults age 56 to 71 that recently published in Neurobiology of Aging, researchers found that after cognitive training, participants’ brains were more energy efficient, meaning their brain did not have to work as hard to perform a task.

To investigate changes in brain efficiency, the research team studied neural activity while the participant performed a task. For the study, 57 cognitively normal older adults were randomly assigned to a cognitive training group, a wait-listed control group, or physical exercise control group. The cognitive training utilized the Strategic Memory Advanced Reasoning Training (SMART) program developed at the Center for BrainHealth.
