WESTCHESTER, Ill. – Insufficient sleep among adolescents may not only contribute to lower grades and a lack of motivation, but may also increase the odds of serious levels of emotional and behavioral disturbances, including ADHD, according to a research abstract that will be presented on Monday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
The study, authored by Fred Danner, PhD, of the University of Kentucky, focused on 882 high school freshmen who provided information about their sleep habits and school grades and also completed psychological and behavioral assessments.Advertisements
Since 1996, Kyla Wahlstrom and her research team at the Center for Applied Research and Educational Improvement (CAREI) have led the way in the study of later start times for high school students, beginning with their study of the impact of later start times on educational achievement in two different districts.
Scientists have known for decades that the ability to remember newly learned information declines with age, but it was not clear why. A new study may provide part of the answer.
The report, posted online on Sunday by the journal Nature Neuroscience, suggests that structural brain changes occurring naturally over time interfere with sleep quality, which in turn blunts the ability to store memories for the long term.
Boys are physically maturing earlier than ever, and pediatricians should warn parents that deeper voices may mean that boys need more, not less, supervision in some ways, according to a European study.
Research at the Max Planck Institute for Demographic Research in Rostock, Germany, noted that the age of sexual maturity has been decreasing by about 2.5 months each decade at least since the middle of the 18th century. But Joshua Goldstein, the institute’s director, said that even though it is widely accepted that girls are maturing earlier and earlier, only recently have researchers been able to actually document that trend for boys.

Here now, for distributing far and wide, is a list of common misconceptions surrounding “Folk Neuroscience” — a term clinical and neuropsychologist Vaughan Bell uses to describe the imprecise, “sometimes wildly inaccurate,” concepts that are commonly used to explain the brain. They’re borrowed from the end of a fantastic feature, published in last Sunday’s Observer, wherein Bell explores how inaccurate depictions of neuroscience have grown in tandem with a burgeoning public interest in the mind and its mechanisms.
