Electrical currents to the brain improve memory for older adults, study finds

The study targeted two areas of the brain linked to memory.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.
Around 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. This new study is only a first look at a potential solution. 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.
The brain stimulation done in this study, published Monday in Nature Neuroscience, came from a swim…
