A study published online as an accepted paper in the Journal of Clinical Sleep Medicine found that later school start times were associated with a significant drop in vehicle accidents involving teen drivers.
While fear memory -- or the ability to remember contexts in which to be afraid -- is important for survival, too much of it, and an inability to forget contexts that no longer apply, hinders daily activities. Recently, scientists from Japan found that a certain opioid drug can help mask some fear memory without causing undesirable side effects. This could make new therapies possible for anxiety disorders like phobias or PTSD.
A new study suggests that for women, poor sleep could contribute to unhealthy food choices, increasing the risk of obesity and heart disease.
Military service is a risk factor for sleep disorders. Recognizing this, the US Departments of Veterans Affairs and Defense issued new guidelines for assessing and treating insomnia and obstructive sleep apnea in military personnel and veterans.
A pre-specified secondary analysis of a double-blind placebo-controlled randomized trial found that low-dose methotrexate (LD-MTX) was associated with a small to modest increase in the risk for some adverse events, including skin cancer and gastrointestinal, infectious, pulmonary, and hematologic effects in patients at risk for heart disease. The risk for kidney-related side-effects was decreased. The findings are published in Annals of Internal Medicine.
The scent of a romantic partner can improve sleep, suggests new psychology research from the University of British Columbia.
A new study of molecular interactions central to the functioning of biological clocks explains how certain mutations can shorten clock timing, making some people extreme 'morning larks' because their internal clocks operate on a 20-hour cycle instead of being synchronized with the 24-hour cycle of day and night. Researchers found that the same molecular switch mechanism affected by these mutations is at work in animals ranging from fruit flies to people.
It is not uncommon for children and teens with autism spectrum disorder to struggle with sleep. To help families, neurologists and other healthcare providers make decisions on the best treatments, the American Academy of Neurology (AAN) has issued a new guideline for sleep problems in children and teens with autism, published in the Feb. 12, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Researchers have discovered through a vast and novel computational library the first molecules that can modulate circadian rhythms by binding with high selectivity to the MT1 melatonin receptor in the brain.
An online survey of nearly 500 veterans with Gulf War illness (GWI) suggests a high burden of disease almost three decades after the conflict.
