Just one night without sleep can increase the amount of the chemical dopamine in the human brain, according to new imaging research in the August 20 issue of the Journal of Neuroscience. Because drugs that increase dopamine, like amphetamines, promote wakefulness, the findings offer a potential mechanism explaining how the brain helps people stay awake despite the urge to sleep.
However, the study also shows that the increase in dopamine cannot compensate for the cognitive deficits caused by sleep deprivation.

There is new promise on the horizon for those who suffer from REM Sleep Behavior Disorder (RBD), according to researchers at the University of Toronto.
RDB, a neurological disorder that causes violent twitches and muscle contractions during rapid eye-movement (REM) sleep, can lead to serious injuries.

Mayo Clinic researchers and a group of international collaborators have discovered a correlation between an extreme form of sleep disorder and eventual onset of parkinsonism or dementia. The findings appear in the current issue of the journal Brain.
Clinical observations and pathology studies, as well as research in animal models, led to the findings that patients with the violent rapid eye movement sleep (REM) behavior disorder (RBD) have a high probability of later developing Lewy body dementia, Parkinson’s disease or multiple system atrophy (a Parkinson’s-like disorder), because all of these conditions appear to stem from a similar neurodegenerative origin.

On an average day, the human mouth will normally produce two to four pints of saliva — enough to fill a half gallon carton of milk. While most people don’t often think about saliva, it plays a role in almost everything that happens in the mouth. It protects, lubricates, and buffers the mouth, and saliva helps people with speaking functions, digesting food, and flowing bacteria away from teeth to keep the mouth clean.
But for millions of people, including many CPAP and BiPAP users, it may feel like their mouths produce almost no moisture at all, possibly hindering these functions. These individuals may suffer from a health condition known as dry mouth, or xerostomia, a feeling of inadequate saliva or dryness in the mouth. Now, Oasis Moisturizing Mouthwash and Mouth Spray, from the makers of Sensodyne, offers solutions for those who suffer from dry mouth.
