http://medicalxpress.com/ en-us Medical Xpress internet news portal provides the latest news on Health and Medicine. Three myths about sleepwalking – sleepwalkers have no memory of their actions, sleepwalkers' behaviour is without motivation, and sleepwalking has no daytime impact – are dispelled in a recent study led by Antonio Zadra of the University of Montreal and its affiliated Sacré-Coeur Hospital. Working from numerous studies over the last 15 years at the hospital's Centre for Advanced Studies in Sleep Medicine at the Hôpital du Sacré-Cœur de Montréal and a thorough analysis of the literature, Zadra and his colleagues have raised the veil on sleepwalking and clarified the diagnostic criteria for researchers and clinicians. http://medicalxpress.com/news/2013-03-sleepwalkers-theyve.html Neuroscience Thu, 14 Mar 2013 04:45:56 EST news282455141 Sleep is disrupted in people who likely have early Alzheimer's disease but do not yet have the memory loss or other cognitive problems characteristic of full-blown disease, researchers at Washington University School of Medicine in St. Louis report March 11 in JAMA Neurology. http://medicalxpress.com/news/2013-03-loss-alzheimer-symptoms.html Alzheimer's disease & dementia Mon, 11 Mar 2013 16:00:03 EST news282221783 Sleeping just five hours a night over a workweek and having unlimited access to food caused participants in a new study led by the University of Colorado Boulder to gain nearly two pounds of weight. http://medicalxpress.com/news/2013-03-weight-gain.html Health Mon, 11 Mar 2013 15:00:07 EST news282221542 (Medical Xpress)—In the first study of its kind, researchers have determined that teens who are homeschooled benefit from healthier sleep habits than those who go to most private and public schools.
