Just like how we stay physically fit by lifting weights and going for runs, our brains also benefit from exercise. In a new study, researchers explored a novel method called cognitive training with neurofeedback to enhance the cognitive abilities of seniors with mild cognitive impairment (MCI). They used a technique called functional near-infrared spectroscopy (fNIRS) to provide feedback on brain activity, specifically in the prefrontal cortex. By engaging in cognitive tasks while receiving this feedback, participants were able to improve their working memory over a period of four weeks. Interestingly, the level of brain activity in the targeted region decreased as participants’ cognitive performance improved. These findings highlight the potential of brain-computer interfaces in enhancing cognitive function among older adults with MCI. The study also underscores the importance of non-pharmacological interventions in managing MCI and preventing further decline. Want to dive deeper into the fascinating world of cognitive training?

IntroductionMild cognitive impairment (MCI) is often described as an intermediate stage of the normal cognitive decline associated with aging and dementia. There is a growing interest in various non-pharmacological interventions for MCI to delay the onset and inhibit the progressive deterioration of daily life functions. Previous studies suggest that cognitive training (CT) contributes to the restoration of working memory and that the brain-computer-interface technique can be applied to elicit a more effective treatment response. However, these techniques have certain limitations. Thus, in this preliminary study, we applied the neurofeedback paradigm during CT to increase the working memory function of patients with MCI.MethodsNear-infrared spectroscopy (NIRS) was used to provide neurofeedback by measuring the changes in oxygenated hemoglobin in the prefrontal cortex. Thirteen elderly MCI patients who received CT-neurofeedback sessions four times on the left dorsolateral prefrontal cortex (dlPFC) once a week were recruited as participants.ResultsCompared with pre-intervention, the activity of the targeted brain region increased when the participants first engaged in the training; after 4 weeks of training, oxygen saturation was significantly decreased in the left dlPFC. The participants demonstrated significantly improved working memory compared with pre-intervention and decreased activity significantly correlated with improved cognitive performance.ConclusionOur results suggest that the applications for evaluating brain-computer interfaces can aid in elucidation of the subjective mental workload that may create additional or decreased task workloads due to CT.
