Electrical discharges that are not strong enough if applied to the brain can cause the memory loss to change, even if it occurred decades ago, even if it was only for a limited time.
Scientists who sought to explore memory loss discovered that the poor performance observed in older people had an association with the faulty circuits of the most important parts of the brain.
They discovered that these regions, if they were simulated with an electric current, could cause the return of mental abilities in retired people, who were deprived of them since their twenties.
The study leader, Dr. Robert Reinhart, stated: "Age-related negative changes are not immutable: we can recover the highest working memory function that I had when I was much younger" .
Together with his colleague John Nguyen, Reinhart traced the decrease in this circuit capacity to the skeptical parts of the brain disconnected.
They tested these stimulators in the brain of young and old people and observed their abilities through a simple task related to checking memory.
The conclusions indicated that about 30 minutes of brain stimulation increased the accuracy of forty-two older people, so that their results were similar to the twenty-twenty-nine age group.
With a rapid increase in the aging population around the world and only limited treatment options accessible to people with dementia and memory loss, the experts welcomed the conclusions of the team as a vital tool for the development of the field.
Dorothy Bishop, a professor at the University of Oxford, said: "There are no indications that the beneficial effects of stimulation persist beyond the experimental session."
Dr. Reinhart affirmed that he was fascinated to see that companies are already committed to bringing this type of technology to the market.
