Gas-blockers might slow down Alzheimer's disease
October 31, 2005A noxious gas speeds up brain degeneration in Alzheimer's disease, according to a study in the November 7 issue of The Journal of Experimental Medicine. Carl Nathan and colleagues at Cornell University Weill Medical College found that an enzyme that triggers the production of nitric oxide (NO) - a gas that helps immune cells fight off invading pathogens - accelerates the formation of brain lesions in Alzheimer's-prone mice. The study suggests that inhibitors of this enzyme (called iNOS) - which have already been produced and tested in humans - might be a promising and thus far overlooked therapy for the treatment of this devastating disease.
Alzheimer's disease is a lethal neurodegenerative disease that causes progressive memory loss and dementia. The disease is associated with a build-up in the brain of abnormal fragments of a resident brain protein called beta-amyloid protein. Researchers have not yet figured out exactly how the fragments of this protein (referred to as A-beta) cause disease, but they have some clues.
For nearly a decade, researchers have known that iNOS was present in the brain lesions of patients with Alzheimer's disease, but nobody had addressed whether its presence was making the disease worse. Nathan and colleagues now show that Alzheimer's-prone mice that lack iNOS live twice as long and develop fewer brain lesions than iNOS-expressing mice. Both groups of mice developed some brain lesions initially, but the iNOS-deficient mice were spared the rapid accumulation of lesions later in life.
Based on these results, Nathan suggests that iNOS inhibitors might turn out to be more effective than current therapies for Alzheimer's disease, which temporarily improve performance on cognitive tests, but do not increase survival.

Alzheimers Disease Current Events and Alzheimers Disease News RSSCold sore virus might play role in Alzheimer's disease
A gene known to be a major risk factor for Alzheimer's disease puts out the welcome mat for the virus that causes cold sores, allowing the virus to be more active in the brain compared to other forms of the gene.
Study offers window into human behavior, brain disease
UCSF scientists have identified a cell population that is a primary target of the degenerative brain disease known as frontotemporal dementia, which is as common as Alzheimer's disease in patients who develop dementia before age 65.
New imaging compound might 'see' Alzheimer's earlier
A new imaging molecule that can detect and map plaques and tangles in the brains of people with Alzheimer's disease could eventually lead to earlier diagnosis of the devastating disease, researchers at the University of California, Los Angeles report in the Dec. 21, 2006, issue of the New England Journal of Medicine.
Testosterone therapy may prevent Alzheimer's disease
Researchers at the University of Southern California have discovered a direct link between loss of testosterone and the development of an Alzheimer's-like disease in mice. They also discovered that testosterone treatment slows progression of the disease.
Androgen therapy may slow progress of Alzheimer's disease
Experiments on mouse models of Alzheimer's disease (AD) suggest that treatment with male sex hormones might slow its progression.
Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease
Scientists collaborating at Cornell University in Ithaca and Weill Cornell Medical College in New York City have identified a panel of 23 protein biomarkers in cerebrospinal fluid that acts as a neurochemical "fingerprint," which doctors might use someday to identify patients living with Alzheimer's disease.
Study shows cats can succumb to feline Alzheimer's disease
Ageing cats can develop a feline form of Alzheimer's disease, a new study reveals. Scientists at the Universities of Edinburgh, St Andrews, Bristol and California have identified a key protein which can build up in the nerve cells of a cat's brain and cause mental deterioration.
Scientists develop a new way to target Alzheimer's disease
The pathological embrace between two proteins plays a key role in the development of Alzheimer's disease by triggering the formation of neuron-killing plaques of amyloid beta protein. Now a group of scientists at NYU School of Medicine have devised a way to reduce amyloid beta deposition by interfering with the deadly embrace of these proteins.
Complaints About Memory Are Associated With Alzheimer-Related Brain Damage
Researchers at Rush University Medical Center found that having complaints about memory problems is associated with changes in the brain related to Alzheimer's disease. They reported their findings in the November 2006 issue of Neurology.
More insight into Alzheimer's disease with Stanford discovery of possible cause
A peacekeeper in the body's defenses against infection may hold the key to understanding-and eventually treating-Alzheimer's disease. Researchers at the Stanford University School of Medicine discovered that when a molecule responsible for dialing down the immune system malfunctions in the brain cells of mice, the rodents develop symptoms of the degenerative brain disease.

Alzheimer's from the Inside Out by Richard Taylor (Author) Receiving a diagnosis of Alzheimer’s disease profoundly alters lives and creates endless uncertainty about the future. How does a person cope with such a life-changing discovery? What are the hopes and fears of someone living with this disease? How does he want to be treated? How does he feel as the disease alters his brain, his relationships, and ultimately himself?
Richard Taylor provides illuminating responses to these and many other questions in this collection of provocative essays. Diagnosed with Alzheimer’s disease at age 61, the former psychologist courageously shares an account of his slow transformation and deterioration and the growing division between his world and the world of others.
With poignant clarity, candor, and even occasional humor, more than... |

FlameEz-Memory, 60 Capsules/Bottle by FlameEz Memory loss is caused by a condition in which cells of the brain are damaged or lost. Dementia and Alzheimer's disease are the common disorders that cause memory loss. Studies have shown that neuron damage begins long before an individual experiences any symptoms and the symptoms are only recognized when many cells have died and the brains can no longer function properly. Unlike many cells in the rest of the body, neurons are not readily regenerated. For this reason, memory loss is a progressive condition that only gets worse, there is no coming back from it. Advanced science has shown critical role of inflammation in Alzheimer's and neurodegenerative diseases. When the brain is injured or infected, cells in the brain called microglia produce inflammatory cytokines. Normally, this... |
