New Genes Linked to Restless Legs Syndrome

Posted 18 Oct 2017 by Drugs.com

WEDNESDAY, Oct. 18, 2017 – Scientists have pinpointed more gene mutations that may cause restless legs syndrome. A new study involving roughly 46,000 people with restless legs syndrome turned up 13 new gene variants that appear to raise the risk for the condition, which affects up to 10 percent of the U.S. and European populations. "We were able to identify a total of 19 risk-associated genetic variants, of which 13 are new. We're confident that our findings will significantly improve our understanding of the molecular causes of restless legs syndrome," said study first author Dr. Barbara Schormair. She's with the Institute of Neurogenomics at the Helmholtz Center in Munich, Germany. People with the condition experience unpleasant sensations in their legs at night, including tingling and the urge to move their legs. For the study, an international team of researchers from the Technical ... Read more

Living With Purpose May Help Seniors Sleep Soundly

Posted 10 Jul 2017 by Drugs.com

MONDAY, July 10, 2017 – Seniors who believe they have a purpose in life may sleep better, researchers say. Those who have good reasons to get up every day are less apt to have problems that keep them awake at night, such as sleep apnea and restless leg syndrome, according to a new study. People tend to have more trouble sleeping as they age, the researchers added. "Helping people cultivate a purpose in life could be an effective drug-free strategy to improve sleep quality, particularly for a population that is facing more insomnia," said study senior author Jason Ong. He's an associate professor of neurology at Northwestern University's Feinberg School of Medicine in Chicago. The study included more than 800 people between the ages of 60 and 100 who did not have dementia. Those who said their lives had meaning were 63 percent less likely to have sleep apnea and 52 percent less likely ... Read more

Scientists Working on Solar-Powered Prosthetic Limbs

Posted 23 Mar 2017 by Drugs.com

THURSDAY, March 23, 2017 – It may be possible to use the sun's energy to power artificial limbs, U.K. researchers report. The University of Glasgow team previously developed an "electronic skin" covering for prosthetic hands made from graphene, a transparent substance that is stronger than steel. Graphene's transparency allows around 98 percent of the light that strikes its surface to pass through it. This makes it ideal for gathering solar energy, the researchers explained in a university news release. In their new study, the scientists integrated photovoltaic cells into their graphene skin. Photovoltaic cells generate power when illuminated. The graphene skin requires just 20 nanowatts of power per square centimeter. That's easily provided by even the poorest-quality photovoltaic cells currently available, the Scottish team noted. Currently, energy generated by the graphene skin's ... Read more

Better Sleep Could Mean Better Sex for Older Women

Posted 1 Feb 2017 by Drugs.com

WEDNESDAY, Feb. 1, 2017 – A more satisfying sex life may be only a good night's sleep away for women over 50, new research finds. Researchers led by Dr. Juliana Kling of the Mayo Clinic in Scottsdale, Ariz., tracked data from nearly 94,000 women aged 50 to 79. The investigators found that 31 percent had insomnia, and a little more than half (56 percent) said they were somewhat or very satisfied with their sex life. But too little sleep – fewer than seven to eight hours a night – was linked with a lower likelihood of sexual satisfaction, the findings showed. "This is a very important study since it examines a question which has tremendous potential impact on women's lives," said Dr. Jill Rabin, who reviewed the findings. She's co-chief of the Women's Health Program at Northwell Health in New Hyde Park, N.Y. Age played a key role in outcomes. For example, the study found that older ... Read more

Study Finds Genetic Link Between Sleep Problems and Obesity

Posted 19 Dec 2016 by Drugs.com

MONDAY, Dec. 19, 2016 – There seems to be a genetic link between poor sleep and some medical conditions, including obesity, restless legs syndrome and schizophrenia, researchers report. "This clinical science is an important step forwards in understanding the biological basis for these conditions, so it's very exciting," said study co-author Dr. Martin Rutter. He is senior lecturer in cardiometabolic medicine at the University of Manchester in England. "Scientists have long observed a connection between sleep disorders and these conditions in epidemiological studies. But this is the first time these biological links have been identified at a molecular level," Rutter said. The researchers, from the University of Manchester and Massachusetts General Hospital in Boston, examined the mapped genes of more than 112,000 people in search of links between the participants' genes and their ...

Specially Designed Video Game Might Ease 'Phantom Limb' Pain

Posted 2 Dec 2016 by Drugs.com

THURSDAY, Dec. 1, 2016 – Amputees who experience what is known as phantom limb pain may benefit from playing a virtual reality game that simulates the movement of missing limbs, a small study suggests. "Phantom limb pain is a difficult condition to treat that can seriously hinder patients' quality of life," said study lead author Max Ortiz Catalan. He is an assistant professor at Sweden's Chalmers University of Technology. Phantom limb pain occurs when amputees feel painful sensations that appear to be coming from limbs that no longer exist. In about one-third of cases, the pain can lead to poor mental health and worsening disability, the study authors noted. "The results from our study suggest that it may be useful to 'exercise' the phantom limb," Catalan explained. "Our treatment offers an engaging way to do this while also providing a non-invasive and non-pharmacological treatment, ... Read more

Exercise Speeds Seniors' Recovery From Disability

Posted 26 Sep 2016 by Drugs.com

MONDAY, Sept. 26, 2016 – Elderly adults who regularly exercise are less likely to suffer a disability – and if they do, they tend to recover faster, a new clinical trial finds. Researchers found that when they got sedentary older adults into an exercise routine, it curbed their risk of suffering a disabling injury or illness. And those who did develop a physical disability were one-third more likely to recover from it, compared to seniors who remained sedentary. Experts said the findings underscore an important message: It's never too late to reap the benefits of exercise. "And it doesn't have to be some heavy-duty regimen. You don't have to join a gym," said Patricia Katz, a professor of medicine at the University of California, San Francisco. In this study, she pointed out, moderate walking was the main activity. Katz wrote an editorial published online with the study Sept. 26 in ... Read more

Amputee 'Feels' With Bionic Fingertip

Posted 9 Mar 2016 by Drugs.com

TUESDAY, March 8, 2016 – A bionic fingertip enabled an amputee to feel different textures, researchers report. The fingertip was linked to electrodes surgically implanted into nerves in Dennis Aabo Sorensen's upper arm. Sorenson was able to feel smoothness and roughness with the fingertip, the researchers said. A machine controlled the movement of the fingertip over pieces of plastic with different rough or smooth patterns. As the fingertip moved over the plastic surfaces, sensors generated electrical signals that were sent to the nerves in Sorensen's upper arm. He could tell the difference between smooth and rough textures 96 percent of the time, the researchers said. The successful test of the bionic fingertip could help speed efforts to develop artificial limbs that provide sensory feedback, according to Silvestro Micera, from Ecole Polytechnique Federale de Lausanne (EPFL) in ...

Artificial Skin Could Bring Sense of Touch to Prosthetics

Posted 15 Oct 2015 by Drugs.com

THURSDAY, Oct. 15, 2015 – In a step toward giving prosthetic limbs a sense of touch, scientists have developed an artificial skin that can "feel" pressure and send those signals to brain cells. Reporting in the Oct. 16 issue of Science, researchers say the plastic skin mimics the ability of human skin to tell the difference between a firm handshake and the dead-fish variety. It can then transmit that information to cells of the central nervous system. So far, the principle has only been tested using brain cells from mice, and much work remains before it could be useful for people with prosthetic limbs. "But, we know what we need to do to move this forward, and I'd estimate this could be available in three to six years," said researcher Alex Chortos, a doctoral candidate at Stanford University, in California. Recent years have seen major advances in the function of prosthetic limbs, and ... Read more
