Study points to potential misuse/abuse of ADHD drugs
A new British Journal of Clinical Pharmacology study indicates that methylphenidate, a central nervous system stimulant approved to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy, may be subject to misuse and/or abuse. (2018-03-07)

ADHD medication linked to slightly increased risk of heart rhythm problems

Study of sleeping fur seals provides insight into the function of REM sleep
All land mammals and birds have two types of sleep: rapid eye movement (REM) and non-REM (also called slow-wave sleep). Earlier evidence had suggested that REM sleep is essential for physical and mental well-being and learning, but the underlying function of REM sleep has been a mystery. Now researchers reporting in Current Biology on June 7 have new insight into the function of REM sleep, based on studies of an unlikely animal: the fur seal. (2018-06-07)

Hormone links sleep, hunger and metabolism, researchers find

Sleepless in Latin America: Blind cavefish, extreme environments and insomnia
A study led by researchers from Florida Atlantic University has found that differences in the production of the neuropeptide Hypocretin, previously implicated in human narcolepsy, may explain variation in sleep between animal species, or even between individual people. It may also provide important insight into the evolution of sleep and how we might build a brain that does not need to sleep. (2018-02-06)

A wakefulness molecule is abundant in the brains of heroin addicts
Researchers have discovered that the brains of heroin addicts harbor a greater number of neurons that produce hypocretin, a molecule involved in arousal and wakefulness, and one lacking in abundance in people with narcolepsy. In mice with narcolepsy, these researchers went on to show, administering morphine -- an opioid similar. (2018-06-27)

Targeted therapy for sleep disorders helps patients with muscular dystrophy
Myotonic dystrophy type 1 (DM1) is the most common adult muscular dystrophy, and many patients with DM1 suffer from various sleep and respiratory disorders. In a study in the current issue of the Journal of Neuromuscular Diseases, researchers found that because there is wide range of sleep problems, treatments do not fit a 'one size fits all' model. (2017-01-13)

Study shows a bidirectional relationship between chronic stress and sleep problems
According to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, people with chronic stress report shorter sleep duration, worse sleep quality, and more daytime functioning impairments.

The findings suggest a different clinical course of treatment for people suffering with Parkinson's that may ameliorate their sleep symptoms. (2007-05-11)

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.

Enhancing sleep after a head injury may help prevent some damage to brain cells, according to a study in rats published March 23 in The Journal of Neuroscience. Researchers at University Hospital of Zurich, Switzerland found that enhancing the slow-wave cycle of sleep after head trauma minimized damage to axons -- the thin extensions that nerve cells use to send signals to other cells -- and helped preserve normal brain function.

Screening to help prevent stroke in kids increases, but limited access a problem
The number of children with a certain blood disorder undergoing an ultrasound to help prevent stroke is up significantly in the past 10 years since the publication of a major study showing its benefits. However, limited access to labs that perform this type of screening appears to be a barrier to helping these children who are at a high risk of stroke. The research is published in the April 14, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology. (2009-04-13)

Is being a morning person in your DNA?

Study links long sleep duration to an increased risk of metabolic syndrome in older adults
Participants reporting a daily sleep duration of eight hours or more including naps were 15 percent more likely to have metabolic syndrome. This relationship remained unchanged after full adjustment for potential confounders.
