"Eszopiclone was well tolerated and significantly improved sleep onset, sleep efficiency, total sleep time and sleep quality over the study period," said McCall, director of the sleep laboratory at Wake Forest University Baptist Medical Center and professor and chairman of the Department of Psychiatry and Behavioral Medicine, in the study published in Current Medical Research and Opinion.
He said eszopiclone significantly reduced wakefulness after sleep had begun, wake time during the sleep period and daytime napping.
McCall said daytime napping was more common in elderly patients with insomnia than in good sleepers and that napping increases with age. "The finding of less daytime napping associated with eszopiclone treatment in the present study could be interpreted as evidence of improvement in some aspects of daytime function in these elderly insomniacs."
The study compared eszopiclone with an inert placebo in patients 64 to 86 years old over a two-week period and used both measurements made in sleep laboratories and patients' own reports of their sleep activity during the study.
The 136 patients in the eszopiclone group reported greater quality of sleep and greater depth of sleep than the 128 patients in the control group, he said. "Upon awakening, patients treated with eszopiclone reported less morning sleepiness compared with placebo."
Since patients were in the study for only two weeks, McCall said longer-term studies are needed to determine the safety of longer treatment. The study – conducted in 49 sleep laboratories -- was the largest sleep-lab-based trial of nightly doses of a sleeping pill in elderly patients with insomnia, he said.
"Chronic insomnia is an under-recognized, under-diagnosed and under-treated disorder that is not only more prevalent in the elderly than the general population, but also potentially serious, as it can be associated with increased risk for injurious falls and impairment of cognitive function, which can be misdiagnosed as dementia," McCall and his colleagues said. "In patients with dementia, insomnia is also the most frequently cited reason for nursing home placement."

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
