Scientists will look at whether diseases such as Alzheimer's can be alleviated using the same method.
Scientists have discovered they can boost people's memory for a least a month by harmlessly stimulating parts of the brain with electricity.
People on the trial wore a cap filled with electrodes. A controlled electrical current, which feels similar to an itch or a tingle, was then used to precisely alter brainwaves in targeted regions of the brain. Scientists think the four rounds of stimulation reinforced those patterns and led to lingering improvements as the brain adapted and rewired itself - known as neuroplasticity.
Becoming more forgetful is often a sign of age, but whether this form of stimulation could aid the aging brain in the real world, beyond word games, is still unknown. Dr Susan Kohlhaas, the director of research at Alzheimer's Research UK, said: "We don't know if brain stimulation techniques have potential to help people with dementia but there is research under way in this area."
