Sleep and Memory

Recent research published in the journal Nature Neuroscience looked at the effects of lighter sleep — which often accompanies aging — on memory skills. The small study involved 18 young people (average age 20) and 15 older adults (average age 72).

Given a memory test after sleeping, the older persons scored 55 percent lower than the young persons. The researchers think that the older adults remembered less than their younger counterparts during the memory task because the older persons’ sleep was not as deep.

With age, sleep may become lighter due to sleep interruptions caused by aches, pains and/or the need to urinate. However, sleep quality can be improved which might, in turn, lead to better everyday memory function.
