In today's Health Matters, interrupted sleep can mess with your memory. That's the finding of a new study at Stanford University.

Mice were used in the study, but most parents of young children, who get up several times a night, know the feeling.Researchers found that when the lab mice were rested, they were highly curious and investigated new objects in their cages.

But, when their sleep was interrupted, they showed signs of memory loss. The findings are published in the "Proceedings of the National Academy of Sciences."
