Shift workers: Sleep loss may cause brain damage, new research says - CNN.com

Cramming in extra hours of shut-eye may not make up for those lost pulling all-nighters, new research indicates.

When the mice lost a little sleep, nerve cells reacted by making more of a protein, called sirtuin type 3, to energize and protect them.
But when losing sleep became a habit, that reaction shut down. After just a few days of "shift work" sleep, the cells start dying off at an accelerated pace.
The discovery that long-term sleep loss can result in a loss of brain cells is a first, Veasey said.
"No one really thought that the brain could be irreversibly injured from sleep loss," she said. That has now changed.
