While studying sleep and the effects that it can have on memory in my classes and research studies, it has been known that sleep does affect memory, but not dramatically. As a college student, the less sleep you get, the less information you retain, which in turn slows down the activity of your brain. As you get older, many functions of your body begins to slow down anyway and without increased functioning of the brain, your memory begins to deteriorate. Many older people do not do activities that promote continuous brain functioning and without doing so, it's apparent that without activity, you lose memory, but many older people get much more sleep than they ever get. Sleep plays a major role in developing Alzheimer's Disease, but other factors must be stated also.
