H1N1-triggered narcolepsy may stem from 'molecular mimicry,' Stanford study finds
In genetically susceptible people, narcolepsy can sometimes be triggered by a similarity between a region of a protein called hypocretin and a portion of a protein from the pandemic H1N1 virus, according to a new study by researchers at the Stanford University School of Medicine. (2013-12-17)

UCLA researchers find new clue to cause of human narcolepsy
UCLA researchers have found that an excess number of brain cells that produce the chemical histamine may cause the loss of other cells that produce hypocretin, the neuropeptide that keeps us awake, elevates mood and alertness, and, by their absence, explains the sleepiness of narcolepsy.

Study identifies how muscles are paralyzed during sleep
Two powerful brain chemical systems work together to paralyze skeletal muscles during rapid eye movement (REM) sleep, according to new research in the July 18 issue of the Journal of Neuroscience.

New research showing how real-life exposure to violence disrupts a child's sleep habits
Violence in a child's world impacts sleep, new research shows. The result is measurable, affected by the severity of the violence and can last over time. The more severe the violence, the more sleep is impacted. Characteristics of the violent act also touch different aspects of the child's sleep. Children who are victimized during a violent event tend to sleep less and more poorly; children who witness homicide have more inconsistent sleep as time passes. (2012-06-13)

Sleep apnea linked to increased risk for carbohydrate craving among diabetics
Researchers are encouraging primary care physicians to screen for sleep apnea in patients with Type 2 diabetes after finding a high risk for sleep apnea among diabetics vs. non-diabetics in a clinic-based sample of 55 patients. They also determined that the sleep apnea appeared to be associated with carbohydrate craving, providing an indication of the magnitude of the risk between sleep apnea and self-reported carbohydrate craving in the diabetic population. (2012-06-13)

Obesity, depression found to be root causes of daytime sleepiness

CPAP found to improve sexual function, satisfaction in men with sleep apnea
A new study found erectile dysfunction in 45 percent of men under age 60 suffering from sleep apnea. CPAP improved sexual function and satisfaction in the majority of men during six months, regardless of their level of ED at the very start. Those with ED had more robust improvements, but many without ED reported improved sexual function and satisfaction. ED is common in OSA patients; the average age of the men in this study was 45. (2012-06-13)

2 new studies show connection between sleepiness and pro-athlete careers
Two new studies have uncovered a link between a pro athlete's longevity and the degree of sleepiness that athlete experiences in the daytime. They show that less-sleepy football players remained with their drafting NFL teams after college, and that attrition rates for sleepier baseball players were higher than MLB averages. This information could be useful for managing player drafts or, if sleepiness causes are addressed, for managing player performance. (2012-06-12)

PAP therapy improves depressive symptoms in all patients with sleep apnea
Study of 779 patients using positive airway pressure (PAP) to treat sleep apnea had improvements in depressive symptoms, even if they followed the prescribed PAP regimen only partly, new study reports. Bigger improvements were seen by using PAP four or more hours/night. Sleep apnea patients often have depressive symptoms, but improvements remained significant in this study even after taking into account a prior diagnosis of depression or anti-depressant use. (2012-06-12)

Sleep apnea persisting into teens can impact life skills, study finds
Sleep apnea numbers decline as kids enter adolescence, but for those with persistent sleep apnea, the teens can be a devastating trial of behavior and learning problems. New research looks at 263 children at two different time periods five years apart and finds kids with persistent sleep apnea have higher rates attention problems, hyperactivity, aggressiveness, difficulties controlling emotions and managing social situations, and a diminished capacity to independently care for themselves. (2012-06-12)

Top risk of stroke for normal-weight adults: Getting under 6 hours of sleep
Habitually sleeping less than six hours significantly increases stroke risk among middle-age to older adults of normal weight and at low risk for sleep apnea, study of 5,666 people followed for up to three years reports. Participants started with no stroke history or high risk for sleep apnea, BMI was adjusted for. First stroke symptoms were measured, along with demographic information, stroke risk factors, depression symptoms, health behaviors. Study found no association among overweight participants. (2012-06-11)

Some adults with sleep disturbances are actually afraid of the dark, study says
Sleep researchers are shedding light on a contributing factor to insomnia maybe hard to admit -- an adult fear of the dark. A pilot study reports that nearly half of the students reporting poor sleep also were found (with objective measurement) to have a phobia of the dark. Researchers said traditional insomnia treatments might not work for these patients, and suggest they be adapted to account for the dark-related phobia. (2012-06-11)

Sleep deprivation may lead to higher anxiety levels, fMRI scans show
New research shows that sleep loss exaggerates anticipation impulses, leading to anxiety issues, particularly among people already highly anxious. Since two common features of anxiety disorders are sleep loss and an amplification of emotional response, results from this study (using fMRI scans) suggest that they may not be independent of one another but interact instead. Activity takes place in the amygdala, associated with responding to negative and unpleasant experiences. (2012-06-10)

MRI scans show how sleep loss affects the ability to choose proper foods
fMRI scans reveal how sleep deprivation impairs higher-order regions in the human brain where food choices are made - not the deeper brain structures reacting to basic desire. This new evidence offers another explanation for the link between sleep loss and obesity. Impaired brain activity in the frontal lobe was observed but not significant differences in areas traditionally associated with basic reward reactivity. Therefore, sleep loss may be more about higher brain functions than cravings. (2012-06-10)

Brain scans show specific neuronal response to junk food when sleep-restricted
The sight of unhealthy food during a period of sleep restriction activated reward centers in the brain less active than with adequate sleep, a new study using fMRI scans shows. Previous research has shown restricted sleep leading to increased food consumption in healthy people and increased desires for sweet and salty food. Results from this study provides additional support for the role of inadequate sleep in appetite-modulation and obesity. (2012-06-10)

3 p.m. slump? Why a sugar rush may not be the answer
A new study has found that protein and not sugar activates the cells responsible for keeping us awake and burning calories. The research, published in the Nov. 17 issue of the scientific journal Neuron, has implications for understanding obesity and sleep disorders. (2011-11-16)

Why narcoleptics get fat
People with narcolepsy are not only excessively sleepy, but they are also prone to gaining weight. In fact, narcoleptic patients will often pack on pounds even as they eat considerably less than your average person. Now researchers reporting in the October issue of Cell Metabolism, a Cell Press publication, appear to have an answer as to why. It seems a deficiency of the neuropeptide hormone orexin, an ingredient that encourages hunger and wakefulness, may leave them with a lack of energy-burning brown fat. (2011-10-04)
