Researchers out of UCLA looked at how we store memories and identifed a mechanism that could potentially help against age-related memory loss. According to the study, our brains “store memories in groups so that the recollection of one significant memory triggers the recall of others that are connected chronologically. As we age, however, our brains gradually lose this ability to link related memories.” The researchers found the mechanism that causes the memory linking and they were able to restore its function in aging mice. These findings suggest “new method for strengthening human memory in middle age and a possible early intervention for dementia.”
