(Ivanhoe Newswire) — Alzheimer´s is a progressive disease that affects approximately 5.3 million Americans, particularly the elderly. These numbers are expected to increase, unless a cure is found. New research shows the higher levels of a certain fat in the blood called ceramides may increase a person´s chance of developing Alzheimer´s disease. Study author Michelle M. Mielke, Ph.D, an epidemiologist with the Mayo Clinic in Rochester, Minn. was quoted as saying, "Our...

Imaging technique offers novel way to monitor neurodegenerative disorders in live animal models of Parkinson's disease Using a two-photon microscope capable of peering deep within living tissue, researchers at the University of California, San Diego School of Medicine have found new evidence that alpha-synuclein protein build-up inside neurons causes them to not only become "leaky," but also to misfire due to calcium fluxes. The findings — the first recorded in vivo using a...

redOrbit Staff & Wire Reports - Your Universe Online Finding may suggest new treatments for sleep disorders Understanding sleep disorders including REM sleep behavior disorder, narcolepsy and grinding of the teeth could be linked to two strong brain chemicals and a system network that works together to stop rapid eye movement and muscle movement during sleep. New research in the July 18 issue of  The Journal of Neuroscience may help scientists better understand and treat sleep...

Early diagnosis without treatment options creates individual, societal conundrum Diagnostic tests are increasingly capable of identifying plaques and tangles present in Alzheimer's disease, yet the disease remains untreatable. Questions remain about how these tests can be used in research studies examining potential interventions to treat and prevent Alzheimer's disease. Experts from the Perelman School of Medicine at the University of Pennsylvania will today participate in a panel at the...

A buildup of sodium in the brain detected by magnetic resonance imaging (MRI) may be a biomarker for the degeneration of nerve cells that occurs in patients with multiple sclerosis (MS), according to a new study published online in the journal Radiology. The study found that patients with early-stage MS showed sodium accumulation in specific brain regions, while patients with more advanced disease showed sodium accumulation throughout the whole brain. Sodium buildup in motor areas of the...

(Ivanhoe Newswire) — A new study marks the beginning of important research that could potentially help develop and assess treatments for multiple sclerosis (MS). Researchers found that patients with early-stage MS revealed a sodium accumulation in certain regions of the brain, and patients with a more advanced stage of the disease showed sodium accumulation throughout the whole brain. There was a direct correlation between sodium buildup in motor areas of the brain and the degree of...

Connie K. Ho for redOrbit.com — Your Universe Online Even though information on Alzheimer´s is relatively sparse, researchers are ramping up their projects to find out more about the disorder. In particular, representatives at the Alzheimer´s Association International Conference in Vancouver recently stated that there´s a possible correlation between sleep quality and quantity with the risk of cognitive decline. Based on a number of studies, they concluded that naps...
