Brain stimulation boosts memory in older people

Study findings could point to new ways to boost brain function in people with dementia and Alzheimer's

Electrical brain stimulation using a non-invasive cap can help boost older people's mental scores to those of people 20-30 years younger, according to a US study.


Age-related decline in working memory can be reversed by stimulating two key brain areas at a specific rhythm, the researchers say in Nature Neuroscience.

The findings are early and only relate to healthy volunteers at this stage, but they could point to ways to boost brain function in people with age-related cognitive decline, such as dementia and Alzheimer's disease.
