Recent research has shown that stimulating the brain with a mild electric current, known as transcranial direct current stimulation, can improve memory.
Researchers at the University of Illinois at Chicago tested these outcomes by having younger and older sets of participants – 48 people between the ages of 18 and 35, as well as 48 adults between the ages of 60 and 79 – try to learn information and remember 60 face-name pairs.
Some of the study participants were given stimulation and others fake stimulation. Their memories were tested immediately after stimulation and again 24 hours later to assess effects on memory. The researchers found that while the younger adults showed memory improvement from stimulation, the older adults did not.
