New research in the FASEB Journal suggests that tangles, 1 of the 2 main Alzheimer's markers, consist of proteins called neurofilaments and vimentin as well as the tau protein Scientists from the National Institutes of Health in the United States have made an important discovery that should forever change the scope and direction of Alzheimer's research. Specifically, they have discovered that the protein tangles which are a hallmark of the disease involve at least three different proteins...

Breakthrough discovery paves way for potential treatments Scientists at the Gladstone Institutes have discovered how a form of the protein linked to Huntington's disease influences the timing and severity of its symptoms, offering new avenues for treating not only this disease, but also a variety of similar conditions. In a paper being published today in Nature Chemical Biology, the laboratory of Gladstone Senior Investigator Steven Finkbeiner, MD, PhD, singles out one form of a...

In a development that sheds new light on the pathology of Alzheimer's disease (AD), a team of Whitehead Institute scientists has identified connections between genetic risk factors for the disease and the effects of a peptide toxic to nerve cells in the brains of AD patients. The scientists, working in and in collaboration with the lab of Whitehead Member Susan Lindquist, established these previously unknown links in an unexpected way. They used a very simple cell type–yeast...

When people dream that they are performing a particular action, a portion of the brain involved in the planning and execution of movement lights up with activity. The finding, made by scanning the brains of lucid dreamers while they slept, offers a glimpse into the non-waking consciousness and is a first step toward true "dream reading," according to a report published online in the Cell Press journal Current Biology on October 27. "Dreaming is not just looking at a dream movie," said...

(Ivanhoe Newswire) — Patients with mild Alzheimer´s disease whose vision improved after a cataract surgery also showed improvement in cognitive ability, mood, sleep patterns and other behaviors.   This is the first study to specifically assess whether cataract surgery could benefit Alzheimer's patients. Thirty-eight patients, average age 85 and all exhibiting mild dementia due to Alzheimer's disease, completed lead researcher Brigitte Girard´s, MD, study. All...

With age, forgetfulness and other signs of memory loss sometimes appear, prompting elderly individuals to seek a medical evaluation amid fears that they may be experiencing early symptoms of Alzheimer's disease (AD), the most common type of dementia among Americans aged 65 and older. But even when early memory problems suggest the potential for impending AD, the actual risk is variable. Some patients are at high risk while others are not. The challenge for doctors has long been to...

Circadian disruption and sleep restriction contributing factors Researchers from Sweden have uncovered an association between shift work and increased risk of multiple sclerosis (MS). Those who engage in off-hour employment before the age of 20 may be at risk for MS due to a disruption in their circadian rhythm and sleep pattern. Findings of this novel study appear today in Annals of Neurology, a journal published by Wiley-Blackwell on behalf of the American Neurological Association and...
