Delirium in ICU patients a predictor of mortality

Between 60 percent to 80 percent of these patients develop a brain dysfunction known as delirium, which according to a group of physicians at Vanderbilt Medical Center is an independent predictor of mortality.

Possible new treatment strategy for Alzheimer's disease

A new study in mice identifies one of the missing steps in how Alzheimer's develops and suggests a possible new treatment strategy, according to researchers at Columbia University Medical Center and Weill Cornell Medical College and their colleagues.

Scientists discover gene for Parkinson's disease

UCL scientists have discovered a new gene implicated in the early development of Parkinson's disease. In a study of families with early onset disease, Professor Nick Wood and colleagues at University College London's Institute of Neurology identified a novel gene which produces a malfunctioning protein that could pave the way for new treatments for Parkinson sufferers.

Liptor helps Alzheimer’s disease

In a small clinical trial enrolling 63 individuals with Alzheimer’s disease, half of those who received atorvastatin (Lipitor) stabilized or improved after one year of treatment, the trial’s principal investigator D. Larry Sparks, Ph.D., reported today at a professional meeting on Alzheimer therapy.

Women get better picture on hormone replacement therapy

Detailed results of the "estrogen-alone" study within the Women's Health Initiative (WHI), which was terminated in early March 2004, are providing some of the first answers to questions about the efficacy of estrogen alone to prevent chronic disease in healthy, postmenopausal women who have had a hysterectomy.

Cinnamon's role as an insulin substitute in type II diabetes

Cinnamon may be more than a spice – it may have a medical application in preventing and combating diabetes. Cinnamon may help by playing the role of an insulin substitute in type II diabetes, according to cellular and molecular studies at the University of California, Santa Barbara, Iowa State University and the U.S. Department of Agriculture.

Alzheimer fact sheet released

Dementia is a syndrome consisting of a number of symptoms that include loss of memory, judgment and reasoning, and changes in mood, behaviour and communication abilities. Alzheimer Disease, the most common form of dementia, accounts for 64 per cent of all dementias in Canada.

Estrogen-alone hormone therapy had no effect on coronary heart disease risk

A large, multi-center heart disease prevention study, part of the Women's Health Initiative (WHI), found that estrogen-alone hormone therapy had no effect on coronary heart disease risk but increased the risk of stroke for postmenopausal women.

Vitamin C can reduce levels of C-reactive protein, a marker of inflammation and chronic disease

Vitamin C supplements can reduce levels of C-reactive protein, a marker of inflammation and chronic disease risk in humans, according to a new study led by researchers at the University of California, Berkeley.

A protein involved in the release of neurotransmitters in the brain is essential to learning and memory

A study published today in Neuron offers the first evidence that lack of this protein - known as RIM1 alpha - causes profound deficits in the learning process. The discovery is a major step in understanding the molecular events that underlie learning and memory - complex processes that can be impaired in human neuropsychiatric disorders such as Alzheimer's disease, mental retardation and schizophrenia.

Alzheimer's live about half as long as those of similar age without dementia

Age, seriousness of impairment, and the severity of other medical conditions are important indicators of how long an individual might survive after an Alzheimer's disease diagnosis, Eric B. Larson, M.D., M.P.H. and colleagues report in the April 6 Annals of Internal Medicine. Study authors include Linda Teri, Ph.D., recipient of an Alzheimer's Association $1 million Pioneer research grant.

Study Identifies Predictors of Alzheimer's Disease Longevity

It's among the first questions asked after someone is diagnosed with Alzheimer's disease: "What can we expect?" It's a tough question that has been difficult to answer. But a new study suggests that assessing several key clinical aspects of the disease soon after diagnosis could help families and physicians better predict long-term survival in individuals with AD.

Common cholinesterase inhibitor eases behavioral symptoms like agitation, depression, and psychosis in patients

The so-called "memory drugs" used to treat Alzheimer's disease and other causes of dementia also ease or prevent a barrage of troublesome behaviors that affect the majority of patients, ultimately lightening the burden on caregivers, researchers have found. They report their results in the March issue of the American Journal of Psychiatry.

Alzheimer’s Association asks for $40 million in additional funding

The Alzheimer’s Association today called on the House of Representatives to provide $40 million in additional funding this year to the National Institutes of Health NIH) to support large-scale clinical trials for treatments that would slow or delay the progression of Alzheimer’s disease.

Joint Research Collaboration to Predict 3-D Protein Structures and Support Drug Discovery

IBM today announced that the University at Buffalo (UB) Center of Excellence in Bioinformatics, The State University of New York, will use IBM technologies and research expertise to study the structure and behavior of human proteins. The outcome of this research could lead to more targeted drugs to treat diseases such as cancer, Alzheimer's, AIDS and multiple sclerosis.

Study tracks behaviour changes in Alzheimer sufferers

Alzheimer’s sufferers are having their DNA measured and behaviour monitored to pinpoint who is most at risk from developing behaviour problems from dementia.

Design of artificial prion may aid fight against mad cow disease

The culprit behind mad cow disease, a.k.a. bovine spongiform encephalopathy, is the most infamous mammalian form of prions. Prions are misfolded proteins that are capable of growing, replicating, and being passed on to daughter cells, that is, they are by themselves heritable. Beyond their disease manifestation, prions also occur naturally in some organisms (such as yeast) and may play important roles in their growth and development. Now, Osherovich and colleagues have identified the amino acid sequences that allow prions to aggregate and replicate, and thereby pass through generations of cells - and prove this by designing an artificial yeast prion that does not exist in nature.

New Theory About Alzheimer's Disease

A group of scientists at The Scripps Research Institute has proposed a new theory about the cause of Alzheimer's disease, the progressive neurodegenerative disorder that currently afflicts some 4.5 million Americans. According to the hypothesis, the disease arises as a consequence of inflammation, which creates abnormal metabolites out of normal brain molecules.

Cigarette Smoking May Lower Rates of Neurodegenerative Diseases like Parkinson's and Alzheimer's

While the health risks of tobacco are well known, several studies have shown that people with a history of cigarette smoking have lower rates of neurodegenerative diseases like Parkinson's and Alzheimer's disease. However, the explanations for nicotine's neuroprotective effects continue to be debated.
