Could Extra Sleep Improve Memory For People With Alzheimer's?

Paul Shaw, PhD, professor of neurobiology at the Washington University School of Medicine, and colleagues conducted their study on three groups of fruit flies - whose brains regulate sleep in a similar way to humans.

In each group of flies, the researchers disabled a gene to cause different memory problems, but all of which interfered with their ability to make new memories.

In one group, the disabled gene triggered the development of a memory condition similar to Alzheimer's disease. Another group of flies had problems making brain connections that encode memories while another group had too many of these brain connections.
