Zeroing in on Alzheimer'sSeptember 25, 2003Hereditary Alzheimer's disease has been shown to be the result of mutations in certain specific genes. Other cases of Alzheimer's are also assumed to be traceable to the influence of a number of still unidentified genes. It is probable that these genes are located in a large area on chromosome 10q, which contains more than 100 genes. Working with researchers in Gothenburg and Los Angeles, scientists at the Karolinska Institute in Stockholm, Sweden have now narrowed down the area of interest on chromosome 10 to include only three genes. The results are being published in the journal Human Mutation Online, September 24, 2003. One of these highly interesting genes codes for the protein insulin degrading enzyme (IDE). This protein is a strong candidate for a role in Alzheimer's owing to its biological function -- it breaks down extracellular amyloid-beta protein, one of the substances that make up the senile plaque that is formed in Alzheimer's. The study has analyzed the DNA from 648 patients with Alzheimer's and 663 healthy individuals. The results show a significant coupling between the limited three-gene region including the gene for IDE and the risk of disease and the severity of the disease.

New data demonstrate potential for early detection of Alzheimer's disease Data published in the June issue of the Journal of Alzheimer's Disease demonstrated that minimally-invasive biospectroscopy was able to identify changes in oxidative stress (OS) levels in blood plasma, which may prove to be a useful biomarker in the early detection of Alzheimer's disease. Another McGill/JGH breakthrough opens door to early Alzheimer's diagnosis A new diagnostic technique which may greatly simplify the detection of Alzheimer's disease has been discovered by researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital (JGH). Measuring brain atrophy in patients with mild cognitive impairment Scientists at the University of California, San Diego School of Medicine have shown that a fully automated procedure called Volumetric MRI - which measures the "memory centers" of the brain and compares them to expected size - is effective in predicting the progression from mild cognitive impairment (MCI) to Alzheimer's disease. Commonly used medications may produce cognitive impairment in older adults Many drugs commonly prescribed to older adults for a variety of common medical conditions including allergies, hypertension, asthma, and cardiovascular disease appear to negatively affect the aging brain causing immediate but possibly reversible cognitive impairment, including delirium, in older adults. Commonly used ulcer drugs may offer treatment potential in Alzheimer's disease In a new study, published in the May issue of Elsevier's Experimental Neurology, scientists at the University of British Columbia have discovered that drugs commonly used to treat ulcers have significant neuroprotective properties, which appear to be enhanced when used in combination with ibuprofen, a widely used anti-inflammatory drug. New test for mysterious metabolic diseases developed at Stanford/Packard Scientists at Stanford University School of Medicine have devised a much-needed way to monitor and find treatments for a mysterious and devastating group of metabolic diseases that arise from mutations in cells' fuel-burning mechanism. Recalibrating 'fight or flight' A Canadian/U.S. research team has reported a novel approach to stimulating recovery from chronic stress disorders. Details of the therapeutic model, which exploits the natural dynamics of the body's "fight or flight" system, are published January 23 in the open-access journal PLoS Computational Biology Vitamin B does not slow cognitive decline in Alzheimer's A clinical trial led by Paul S. Aisen, M.D., professor of neurosciences at the University of California, San Diego School of Medicine, showed that high-dose vitamin B supplements did not slow the rate of cognitive decline in patients with mild to moderate Alzheimer disease. Protecting patient privacy the new fashioned way Protecting patient privacy has been recognized as the duty of health-care providers for about as long as doctors have seen patients. In 1996 that duty became a legal obligation when Congress passed the Health Insurance Portability and Accountability Act. More Alzheimer Disease Current Events and Alzheimer Disease News Articles |
