Electric shocks which are not strong enough if applied to the brain can result in the reversal of memory loss even if caused decades ago, if only for a restricted time.
Scientists who were in the pursuit of exploring memory loss discovered that the poor performance observed in the older people had an association with the defective circuits in the most vital parts of the brain.
They found that these regions if stimulated with an electrical current could result in the return of mental abilities in the retired people who were deprived of that since their twenties.
The leader of the study, Doctor Robert Reinhart stated: “Negative age-related changes are not unchangeable – we can bring back the more superior working memory function you had when you were much younger.”
Along with his colleague John Nguyen, Reinhart mapped out the decline in this ability to circuits in the sophisticated parts of the brain becoming disconnected.
They tested these stimulators in the brain of young and older people and observed their abilities through a simple task related to memory check.
The findings indicated that nearly 30 minutes of brain stimulation increased the accuracy of forty-two older people so their results had resemblance with the age group of twenty to twenty-nine.
With a swift increase in the aging population worldwide and only a limited treatment options accessible for those with dementia, and memory loss, experts welcomed the findings of the team as a vital tool for development in the field.
Professor at the University of Oxford, Dorothy Bishop said: “There is no indication that any beneficial effects of stimulation persist beyond the experimental session.”
Doctor Reinhart said he was fascinated to see that companies are already engaged to bring this type of technology to the market.
