The research team divided 60 participants between the ages of 65 and 88 into three groups: one group wore the device but didn’t get any electrical stimulation the second received stimulation in the region associated with working memory and the third received stimulation in the area associated with long-term memory. The research team was interested in two main areas: one that’s linked with working memory (which holds information temporarily and overlaps with short-term memory) and another linked with long-term memory. The brain stimulation done in this study, published Monday in Nature Neuroscience, came from a swim cap-like device studded with electrodes positioned to deliver the electric current to specific areas of the brain. But easy, quick treatments like this one could become even more important as the world’s population rapidly ages - especially if future research shows that it can help with more serious cognitive conditions. This new study is only a first look at a potential solution.

Pulsing electrical currents through the brain for 20 minutes can boost memory for older adults for at least a month, according to a new study.Īround 8 percent of people in the US get diagnosed with Alzheimer’s disease or dementia as they get older - significantly impairing their memory - and an even larger group of older adults has some degree of age-related memory loss.
