Electrical brain stimulation can boost memory function in older people.
LONDON - Electrical brain stimulation using a non-invasive cap can help boost older people's mental scores to those of people 20 to 30 years younger, according to a study published on Monday.
The findings are early and only relate to healthy volunteers at this stage, but could point to new ways to boost brain function in people with age-related cognitive decline such as dementia and Alzheimer's patients. The study involved 42 younger adults aged 20 to 29 and 42 older adults aged 60 to 76, who were all assessed for their performance in a working-memory task.
While receiving active brain stimulation, older adults improved their working-memory test scores to the levels of the younger people. The effect lasted for at least 50 minutes after the stimulation was given, said Robert Reinhart, a researcher at Boston University in the United States who co-led the study.
