The secret connection between anxiety and sleep
A new study reveals a role of the BNST GABAergic system in sleep/wakefulness control, especially in shifting animals' behavioral states from NREM sleep to wakefulness. It also provides insight into the pathophysiology of insomnia and the role of orexin in arousal regulation.

Deep sleep maintains the learning efficiency of the brain
For the first time, researchers have demonstrated the causal context of why deep sleep is important to the learning efficiency of the human brain. They have developed a new, non-invasive method for modulating deep sleep in humans in a targeted region of the brain.

Insomnia associated with increased risk of heart attack and stroke
A meta-analysis assessing the association between insomnia symptoms and incidence or death from cardiovascular disease, stroke, or a combination of events found that difficulty initiating sleep, difficulty maintaining sleep, and non-restorative sleep were significantly associated with higher risks of cardiovascular and stroke events.

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.
