Circadian Therapeutics, a life sciences spinout of Oxford University, has been established to identify and bring to market pharmaceutical and diagnostic platforms ...

Sleep helps process traumatic experiences

If we sleep in the first 24 hours after a traumatic experience, this helps pigeonhole and process the distressing memories more effectively, as researchers from the University of Zurich and the Psychiatric University Hospital Zurich demonstrate in a new study. Sleep could thus be used as an early prevention strategy for posttraumatic stress disorders. ... Full story

Neurons paralyze us during REM sleep

During REM sleep, the brain inhibits the motor system, which makes the sleeper completely immobile. CNRS researchers working in the Centre de Recherche en Neurosciences de Lyon (CNRS/Université Claude Bernard Lyon 1/INSERM/Université Jean Monnet) have identified a population of neurons that is responsible for this transient muscle paralysis. The animal model created will shed light on the origin of some paradoxical sleep disorders, and more particularly the condition that prevents this paralysis. It will also be most useful in the study of Parkinson's disease, since these pathologies are related. This work was published on December 12, 2016 on the website of the journal Brain. ... Full story

Lack of Sleep Costing UK Economy Up to £40 Billion a Year

•Lower productivity levels and the higher risk of mortality resulting from sleep deprivation have a significant effect on a nation's economy. •Sleep deprivation increases the risk of mortality by 13 per cent and leads to the UK losing around 200,000 working days a year. •Increasing nightly sleep from under six hours to between six and seven hours could add £24 billion to the UK economy. ...

Sleep disorders: 3D video monitoring with intelligent software as new analysis option

Vienna - The usual method of recording periodic leg movements in sleep for people with sleep disorders is to use electromyography (EMG), an electrophysiological method used in neurological diagnosis that measures muscle activity. However, the cables that this method requires can interfere with the patient's sleep and electrodes can become detached, thereby compromising the quality of the data. In a study led by MedUni Vienna’s Department of Neurology, Austrian scientists have now demonstrated that superior data can be obtained using supplementary 3D scene analysis of movements, which is now being used for the first time. ...

Poor sleep may increase risk for irregular heart rhythms

•Poor sleep – even if you don’t have sleep apnea – may be linked to higher risks of developing an irregular heartbeat. •In addition, getting less rapid-eye movement (REM) sleep may also be linked to higher atrial fibrillation risks. ... Full story
