#Another Fatal Brain Disease May Come from the Spread of'Prion'Proteins A rare and fatal brain disorder called multiple system atrophy (MSA) may be caused by a newly discovered prion, a protein similar to the ones
Eventually, the buildup of misfolded proteins can cause lesions to form in the brain, leading to disease."
Because prion diseases can be transmitted through certain types of contact with infected tissue, the findings suggest a potential concern for doctors
The disease is rare: About three out of 100,000 Americans over age 50 are diagnosed with MSA yearly.
"We conclude that MSA is a transmissible human neurodegenerative disease caused by alpha-synuclein prions,
and even other similar diseases, such as Parkinson's.""We do not yet know whether or not MSA prions exhibit the same ability to stick to surgical instruments,
and that there is no evidence that MSA spreads in the way that other prion diseases do.
Dr. Valerie Sim, of the Centre for Prions and Protein Folding Diseases at the University of Alberta in Canada, said that the traditional definition of a prion is an infectious protein that can transmit disease to another host.
because brain tissue from MSA patients did not cause disease in normal mice. Rather brain tissue from MSA patients caused disease only in mice that were engineered genetically to have a mutant alpha-synuclein protein.
In contrast,"true"prions can cause disease in normal mice, Sim said.)""The problem with branding something a prion is it induces fear,
because people have heard of it as a scary transmissible disease, "Sim said. But the new study,
"if anything, shows MSA is not easily transmissible, "she said. Still, the new findings are important to consider in research and treatment of MSA,

#White blood cell Mediated Therapy for Neurons in Patients with Parkinson Disease Scientists at the University of North carolina at Chapel hill have begun researching the delivery of neurotropic factors to the brain as a potential therapeutic for Parkinson disease.
However, one potential therapy is the development of smarter immune cells that deliver neurotropic factors to neurons damaged by the disease.

#Blood test to Detect Alzheimer Disease Close to Development Early detection presents new opportunities to slow or perhaps even halt disease progression.
Researchers from the Rowan University School of Osteopathic Medicine are nearing development of a blood test that can accurately detect the presence of Alzheimer disease,
which would give physicians an opportunity to intervene at the earliest, most treatable stage. Robert Nagele, Phd, presented his team most recent findings October 18 at OMED 15 in Orlando.
Dr. Nagele work focuses on utilizing autoantibodies as blood-based biomarkers to accurately detect the presence of myriad diseases
and pinpoint the stage to which a disease has progressed. By detecting Alzheimer disease long before symptoms emerge
Dr. Nagele hopes those with disease-related autoantibody biomarkers will be encouraged to make beneficial lifestyle changes that may help to slow development of the disease.
The blood test developed by Dr. Nagele has shown also promise in detecting other diseases, including Parkinsons, multiple sclerosis and breast cancer.

because we now know that many of the same conditions that lead to vascular disease are also significant risk factors for Alzheimer.
People found to have preclinical disease can take steps to improve their vascular health, including watching their diet,
exercising and managing any weight and blood pressure issues to help stave off or slow disease progression,
Nagele said. While the cause of Alzheimer remains elusive, it is clear that maintaining a healthy blood-brain barrier is a critical preventative measure.
The blood test developed by Dr. Nagele has shown also promise in detecting other diseases, including Parkinsons, multiple sclerosis and breast cancer.
An individual autoantibody profile is influenced strongly by age, gender and the presence of specific diseases or injuries;
Diseases cause characteristic changes in autoantibody profiles that, when detected, can serve as biomarkers that reveal the presence of the disease.
