Untreated sleep apnea in children can harm brain cells tied to cognition and mood A study comparing children 7 to 11 years old with moderate or severe obstructive sleep apnea to children the same age who slept normally found significant reductions of gray matter -- brain cells crucial to most cognitive tasks -- in several regions of the brains of children with sleep apnea. The finding points to connections between this common sleep disturbance and the loss of neurons or delayed neuronal growth in the developing brain.
Abnormal development of the brain in an intractable disease, thanatophoric dysplasia Thanatophoric dysplasia (TD) is an intractable disease with abnormalities of bones and the brain. Because of experimental difficulties, its pathophysiology is largely unknown. In this study, by combining ferrets, whose brain is rather similar to that of humans, and unique technique developed by the present researchers, neuronal translocation along radial glial fibers to the cerebral cortex during fetal brain development has been discovered to be aberrant, which suggests the cause underlying TD.

Scientists are gauging how mood influences eating habits Many of us lie or can’t remember what we ate when asked to reveal our eating habits, and that makes it difficult for doctors and researchers to guide us toward better diets and behaviors. But what if there was a way for them to monitor us? Donna Spruijt-Metz, director of the mHealth Collaboratory at the [...]
A prescription for touch: Early experiences shape preterm babies’ brains Newborn babies experience the world through touch. Now, researchers who have measured the brain responses of 125 infants–including babies who were born prematurely and others who went full-term–show that a baby’s earliest experiences of touch have lasting effects on the way their young brains respond to gentle touch when they go home. The findings reported [...]
A preference for casual sex increases risk of harassment Adolescents who sexually harass others have had casual sex more often than those who do not harass others. They also fantasize more about casual sex and find it more acceptable to have sex without any commitment or emotional closeness. What may be even more surprising is that adolescents who have been sexually harassed are more [...]
Treating cocaine addiction by reducing our appetite for drugs? The hypocretin/orexin (HCRT) system of the brain is best known for promoting wakefulness and appetite. A new paper in Biological Psychiatry suggests that blocking hypocretin signaling via the HCRT-1 receptor (HCRT-R1) might also reduce the appetite for cocaine. The study, led by first author Dr. Brooke Schmeichel in George Koob’s laboratory at the National Institute [...]
Study: Improving your sleep quality is as beneficial to health and happiness as winning the lottery Improving your sleep quality is as beneficial to health and happiness as winning the lottery, according to research by the University of Warwick.

Psychology turns to online crowdsourcing to study the mind, but it’s not without its pitfalls You may not know this, but a great deal of our data about the human mind is based on a relatively small but intensively studied population: first-year undergraduate university students. There has long been concern about the over-reliance on students as a source of data, particularly around lack of demographic diversity and limited sample sizes. [...]
Patient in Chief Diagnosing Donald Trump from afar comes with a cost--including further dividing the country. Understanding the debate--and the one way we might heal as a nation.
Class and family structure alienate young middle-class black women from other women of the same race The presumed sisterhood between young black women in the United States doesn’t exist between the different classes. In fact, a tense relationship is actually par for the course between poorer black women and their more affluent counterparts, with those in the middle and upper classes feeling like shunned “stepsisters.” Young middle-class black women feel “different” [...]
Delirium in critically ill children admitted to intensive care units common and widespread One out of every four children admitted to intensive care units (ICUs) for critical illness develops delirium, according to an international study led by Weill Cornell Medicine and NewYork-Presbyterian investigators. The researchers also found the prevalence of delirium nearly doubles after five days of hospitalization in a pediatric ICU, underscoring the need for routine monitoring [...]
Empathy from the sick may be critical to halting disease outbreaks A little empathy can go a long way toward ending infectious disease outbreaks. That’s a conclusion from researchers at the Georgia Institute of Technology, who used a networked variation of game theory to study how individual behavior during an outbreak of influenza – or other illness – affects the progress of the disease, including how [...]
