Lack of sleep can provoke sleepwalking

Université de Montréal team publish results in Annals of Neurology

Sleepwalkers are advised to keep a regular bedtime to avoid unwanted evening strolls, according to research from the Université de Montréal. Somnambulism, which affects up to four percent of adults, can cause mental confusion or bouts of amnesia in those affected as they wander unresponsive to their environment.

In a recent issue of the Annals of Neurology, the official journal of the American Neurological Association, authors Antonio Zadra, Mathieu Pilon and Jacques Montplaisir explain how they evaluated 40 suspected sleepwalkers. Each was referred to the Sleep Research Centre at Sacré-Coeur Hospital, a Université de Montréal teaching hospital, between August 2003 and March 2007.

“Our study found that sleep deprivation can precipitate sleepwalking in predisposed individuals,” said lead investigator Antonio Zadra. “Sleepwalkers are best to maintain a regular bedtime and avoid sleep deprivation if they wish to steer clear of somnambulism.”

One night of sleep, one night awake

Subjects who took part in the study agreed to have their baseline sleep patterns monitored during an initial all-night assessment. During a subsequent visit, patients were kept awake for the entire evening and remained under constant supervision.

Recovery sleep was allowed the next morning after patients had been awake for 25 hours. Subjects were videotaped during each sleep period as the research team evaluated their behaviour, which ranged from playing with bed sheets to trying to jump over the bed rails. Subjects were evaluated on a three-point scale based on the complexity of their actions.

Results were striking. During baseline sleep, only half of patients exhibited some 32 behavioral episodes. During recovery sleep, 90 percent of patients demonstrated a total of 92 behavioral episodes.

The study also found that sleepwalkers, previously thought to suffer from an inability to sustain slow-wave or deep sleep, had increased difficulty in passing from slow-wave sleep to another sleep stage or to be fully awake following sleep deprivation. “This research also reveals that objective methods can now be used for investigating and diagnosing sleepwalking,” said Dr. Zadra.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
