Geographic variation of human gut microbes tied to obesity Posted: 14 Feb 2014 02:31 PM PST People living in cold, northern latitudes have bacteria in their guts that may predispose them to obesity, according to a new study by researchers at the University of California, Berkeley, and the University of Arizona, Tucson. The researchers’ analysis of the gut microbes of more than a thousand people from around the world showed that those living in northern latitudes had more gut bacteria that have been linked to obesity than did people living farther south. read more

Researchers find increased sleep apnea risk in study of MS patients Posted: 14 Feb 2014 02:19 PM PST People with multiple sclerosis (MS) might assume that the fatigue they often feel just comes with the territory of their chronic neurological condition. But a new University of Michigan study suggests that a large proportion of MS patients may have an undiagnosed sleep disorder that is also known to cause fatigue. And that disorder – obstructive sleep apnea – is a treatable condition. read more

Two Parents with Alzheimer’s Disease? Disease May Show up Decades Early on Brain Scans Posted: 14 Feb 2014 02:06 PM PST People who are dementia-free but have two parents with Alzheimer’s disease may show signs of the disease on brain scans decades before symptoms appear, according to a new study published in the February 12, 2014, online issue of Neurology, the medical journal of the American Academy of Neurology. read more

Can Citrus Ward Off Your Risk of Stroke? Posted: 14 Feb 2014 01:57 PM PST Eating foods that contain vitamin C may reduce your risk of the most common type of hemorrhagic stroke, according to a study released today that will be presented at the American Academy of Neurology’s 66th Annual Meeting in Philadelphia, April 26 to May 3, 2014. read more

Passive smoking impairs children’s responses to asthma treatment Posted: 14 Feb 2014 01:47 PM PST Children exposed to cigarette smoke at home have lower levels of an enzyme that helps them respond to asthma treatment, a study has found.   Passive smoking is known to worsen asthma symptoms in children and impair their response to inhaled steroid treatment, but how this effect occurs was not known.   read more

Impaired recovery from inflammation linked to Alzheimer's disease Posted: 14 Feb 2014 01:35 PM PST New research from Karolinska Institutet shows that the final stage of the normal inflammatory process may be disrupted in patients with Alzheimer's disease. A study published in the journal Alzheimer's & Dementia shows that levels in the brain and cerebrospinal fluid of the molecules necessary for tissue recovery through the clearance of harmful inflammatory substances are lower than normal in patients with Alzheimer's disease. The study also showed association between the lower levels of these molecules with impaired memory function. read more
