New study suggests brain-zapping cap improves short-term memory loss in older adults

A new study says that a cap filled with electrical currents can improve short-term memory loss for older adults when zapped into their brains.

The study used 150 participants between ages 65-88 who had not been diagnosed with a neurological disorder. While asking them to recall five lists of 20 words, the participants were zapped with a mild electrical current to their brain using the cap. The process took 20 minutes and was done over the course of four consecutive days. 

The memory of the participants improved by over 50% compared to the placebo group who did not receive the treatment. The study found that the group was able to recall four to six more words than the placebo participants of a similar age.
