Sleep Deprivation And Memory Loss

A good night's sleep may be the best gift you can get this holiday season.

A new study says when the brain does not get enough rest, it simply stops making certain kinds of cells, contributing to memory and learning difficulties.

The research from Princeton shows that when lab rats go without sleep for 72 hours, levels of a stress hormone go way up.

That increase may explain why the brain stops producing brain cells in an area that is known for making new memories.
