High-resolution images show how the brain resets during sleep
Striking electron microscope pictures from inside the brains of mice suggest what happens in our own brain every day: our synapses grow strong and large during the stimulation of daytime, then shrink by nearly 20% while we sleep, creating room for more growth and learning the next day. The 4-year research project published today in Science offers a direct visual proof of the “synaptic homeostasis hypothesis.”

Chronic sleep deprivation suppresses immune system
Researchers took blood samples from 11 pairs of identical twins with different sleep patterns and discovered that the twin with shorter sleep duration had a depressed immune system, compared with his or her sibling. The findings of this study, one of first conducted outside of sleep lab, were published January 25th in the journal Sleep.

AASM response to ‘Screening for Obstructive Sleep Apnea in Adults: Evidence Report’
The American Academy of Sleep Medicine recommends screening patients who have a high risk for OSA, even if they don't have any sleep-related symptoms. Screening high-risk populations could improve the quality of life and health outcomes for these patients and also reduce the individual and public health burden of untreated OSA.

Foot wrap offers alternative to medication for patients with restless legs syndrome
Authors from Lake Erie Research Institute in Pennsylvania report an adjustable foot wrap used to treat restless legs syndrome is 1.4 times more effective than the standard pharmaceutical treatment. The small pilot study is published today in The Journal of the American Osteopathic Association.

Shift work unwinds body clocks, leading to more severe strokes
A new study using an animal model has found that shift work can lead to more severe ischemic strokes outcomes, in terms of both brain damage and loss of sensation and limb movement. Also that in males, the gravity of stroke outcomes in response to shift work schedules was much worse than in females.

Scientists find gene responsible for sleep deprivation and metabolic disorders
Researchers at Florida Atlantic University have established that translin is an essential integrator of sleep and metabolic state, with important implications for understanding the neural mechanism underlying sleep deprivation in response to environmental challenges. These findings will be published in the April 4 issue of Current Biology.

New research highlights need to give greater consideration to sleep in stroke care
Researchers identify sleep as a problem in patients with stroke, and highlight the need to give greater consideration to sleep in stroke care, and in particular stroke rehabilitation. The findings from the University of Surrey and University of Freiburg are published in PLOS ONE.

Changes in heart activity may signal epilepsy
Research published online in the Journal of Neurophysiology suggests that changes in the parasympathetic tone precede the onset of epilepsy in children. Also that pronounced alterations in heart rate variability may contribute to sudden unexpected death in epilepsy (SUDEP).

Sleep changes seen with fetal alcohol exposure partly explain learning and mood problems
According to a study recently published online in the journal Neuroscience, exposure of a developing brain to binge levels of alcohol results in a permanent fragmentation in slow-wave sleep, with the extent of the fragmentation influencing the severity of related cognitive disorders.
