(MEDICALNEWSTODAY) — Poor quality sleep among the elderly can cause significant memory loss and brain deterioration, according to a recent study by researchers at the University of California, Berkeley. The study is the first of its kind to confirm the link between poor sleep and memory loss.

The researchers found that during sleep important brain waves are produced which play a vital role in storing memories. The brain waves transfer memories from a part of the brain called the hippocampus to the prefrontal cortex, a part of the brain where long term memories are stored.

Poor quality sleep in adults causes memories to stay stuck in the hippocampus and not reach the prefrontal cortex. This results in forgetfulness and difficulty remembering names.
