Disruption of cytoskeleton pathways contribute to ALS pathogenesis A new genetic mutation that causes familial amyotrophic lateral sclerosis (ALS), a fatal neurological disorder also known as Lou Gehrig's Disease, has been identified by a team of scientists led by researchers at the University of Massachusetts Medical School (UMMS). Mutations to the profilin (PFN1) gene, which is essential to the growth and development of nerve cell axons, is estimated to account for one to two percent of...

NIH-supported research provides more complete picture of the disease Researchers have linked newly discovered gene mutations to some cases of the progressive fatal neurological disease amyotrophic lateral sclerosis — ALS, also known as Lou Gehrig's disease. Shedding light on how ALS destroys the cells and leads to paralysis, the researchers found that mutations in this gene affect the structure and growth of nerve cells. ALS attacks motor neurons, the nerve cells responsible for...

Connie K. Ho for redOrbit.com - Your Universe Online Scientists from the Washington University School of Medicine recently revealed that they have developed a “timeline” that shows early signs of Alzheimer´s, even with unseen progress. The team of researchers examined families who had a genetic risk of having the disease. The findings, which were published recently in the New England Journal of Medicine, show that signs of Alzheimer´s can appear up to 25 years...

Simulations by UC Santa Barbara researchers improve understanding of plaque formation and suggest new diagnostic and treatment options Alzheimer's disease is one of the most dreaded and debilitating illnesses one can develop. Currently, the disease afflicts 6.5 million Americans and the Alzheimer's Association projects it to increase to between 11 and 16 million, or 1 in 85 people, by 2050. Cell death in the brain causes one to grow forgetful, confused and, eventually, catatonic....

Research published today in Biomed Central's open access journal Journal of Neuroinflammation suggests that chronic inflammation can predispose the brain to develop Alzheimer's disease. To date it has been difficult to pin down the role of inflammation in Alzheimer's disease (AD), especially because trials of NSAIDs appeared to have conflicting results. Although the ADAPT (The Alzheimer`s Disease Anti-inflammatory Prevention Trial) trial was stopped early, recent results suggest that...

Our eyes don´t just take in the world around us, they can also reflect our emotional state, influence our memories, and provide clues about the way we think. Here is some of the latest research from the journals Psychological Science and Current Directions in Psychological Science in which scientists show there´s much more to the eyes than people might think. Pupil Dilation Reflects the Creation and Retrieval of Memories Many people know that our pupils shrink when our eyes...

Long-term aim is to develop new treatments to block the spread of damaged proteins in the brain Van Andel Institute announces that researchers at Lund University in Sweden have published a study detailing how Parkinson's disease spreads through the brain. Experiments in rat models uncover a process previously used to explain mad cow disease, in which misfolded proteins travel from sick to healthy cells. This model has never before been identified so clearly in a living organism, and the...

An international team led by human genetic researchers at the University of British Columbia and Vancouver Coastal Health has identified the latest gene associated with typical late-onset Lewy body Parkinson's disease (PD), with the help of a Canadian Mennonite family of Dutch-German-Russian ancestry. Twelve of the 57 members of the Saskatchewan family who participated in the study had previously been diagnosed with PD. UBC Medical Genetics Prof. Matthew Farrer, who led the research,...

In a recent Journal of Biological Chemistry "Paper of the Week," research led by Ayae Kinoshita at the Kyoto University Graduate School of Medicine in Japan reveals the benefits of exercise in combating Alzheimer's disease. The most common cause of dementia, Alzheimer's disease results in the loss of cognitive faculty. In the majority of cases, Alzheimer's disease occurs after age 65, and factors such as diet and exercise appear to play a role in its development, with high-fat diets as a...
