Washington: Scientists at the University of California, Berkeley have for the first time found a link between poor sleep, memory loss and brain deterioration in older adults.They have found that the slow brain waves generated during the deep, restorative sleep we typically experience in youth play a key role in transporting memories from the hippocampus - which provides short-term storage for memories - to the prefrontal cortex`s longer term "hard drive."However, in older adults, memories may be getting stuck in the hippocampus due to the poor quality of deep `slow wave` sleep, and are then overwritten by new memories, the findings suggested.Their discovery opens the door to boosting the quality of sleep in elderly people to improve memory."What we have discovered is a dysfunctional pathway that helps explain the relationship between brain deterioration, sleep disruption and memory loss as we get older - and with that, a potentially new treatment avenue," said UC Berkeley sleep researcher Matthew Walker, an associate professor of psychology and neuroscience at UC Berkeley and senior author of the study.
