Can a Lack of Sleep Cause Psychiatric Disorders?
Study shows that sleep deprivation leads to a rewiring of the brain's emotional circuitry

By Nikhil Swaminathan

There's no question that people need their sleep: studies have linked a lack of shut-eye to everything from disruptions in the immune system to cognitive deficits to weight control.

In fact, psychologist Matthew Walker of the University of California, Berkeley, says that "almost all psychiatric disorders show some problems with sleep.'' But, he says that scientists previously believed the psychiatric problems triggered the sleep issues. New research from his lab, however, suggests the reverse is the case; that is, a lack of shut-eye is causing some psychological disturbances.

Walker's team and collaborators from Harvard Medical School reached their conclusions, published in Current Biology, after studying 26 healthy students aged 24 to 31 after either an all-nighter or a full night's sleep.
