Washington, Feb 24 - The growing demand for shark fin soup is not only endangering the marine species, but is also a deadly threat to brain health because of high neurotoxin levels.
University of Miami (UM) scientists discovered high concentrations of neurotoxin BMAA in shark fins, linked with neurodegenerative diseases such as Alzheimer's and Lou Gehrig's Disease.
Washington, Feb 20 - Drugs for Alzheimer's disease currently undergoing clinical trials may have adverse side-effects, warns a new study.
The drugs could act like a bad electrician, causing neurons (nerve cells) to be miswired and tripping their ability to message the brain, suggests the study.
London, Jan 26 : Scientists have made a breakthrough in understanding the causes of Alzheimer's disease, which could potentially lead to the development of new drugs to treat it.
London, Sept 14 : A new study has found that large doses of B-vitamins could slow the cognitive decline in older people that is the precursor to dementias such as Alzheimer's disease.
Washington, Sep 13 - People with high cholesterol may have a higher risk of developing Alzheimer's disease, a study says.
"We found that high cholesterol levels were significantly related to brain plaques associated with Alzheimer's disease," said study author Kensuke Sasaki, of Kyushu University in Fukuoka, Japan, in a press release.
Washington, August 17: Moderate social drinking - a maximum of two drinks per day for men and 1 drink per day for women - significantly reduces the risk of dementia and cognitive impairment, according to a new study.
Washington, July 21: Scientists have discovered that inherited forms of Alzheimer's disease may be detected as early as 20 years before problems with memory and thinking develop.
They say the results demonstrate the feasibility of clinical trials to prevent Alzheimer's in patients who are at risk.
London, July 19 : A study has found that Alzheimer's can be prevented by making some simple lifestyle changes like smoking less and exercising more.
Study author Dr Deborah Barnes, from San Francisco VA Medical Centre, called the findings "exciting".
Washington, July 14 : A new study has found that metallic molecules can highlight Alzheimer's roots when they naturally attach themselves to a collection of beta amyloid proteins called fibrils.
Fibrils form plaques in the brains of Alzheimer's sufferers, and when the molecules, complexes of dipyridophenazine ruthenium, latch onto amyloid fibrils, their photoluminescence increases 50-fold.
Washington, June 30 : An unidentified component of coffee interacts with the beverage's caffeine which seemingly offers protection against Alzheimer's.
A new mouse study by University of South Florida has found that this interaction boosts blood levels of a critical growth factor that seems to counteract Alzheimer's disease process.
Washington, June 28: A new study has revealed that cinnamon has the potential to prevent the degenerative brain disorder, Alzheimer''s disease, which affects at least one in eight Americans over the age of
A team of researchers from the Tel Aviv University (TAU) discovered `Ceppt', the cinnamon extract obtained from its bark that curbs the progression of Alzheimer''s.
London, June 24 : Scientists designed molecular inhibitors that could delay the onset of Alzheimer's disease and prevent the sexual transmission of HIV.
Washington, June 21: Scientists have shown a molecular chaperone is working like a waste management company to collect and detoxify high levels of toxic amyloid beta peptide found in Alzheimer''s disease.
It was known that the molecular chaperone, HspB1, was present in the hallmark plaque of Alzheimer''s patients but its role remained a mystery.
Washington, June 3: Researchers have developed a new `prodrug' slow-release compound that can protect mice from the neurodegenerative effects of both Huntington''s and Alzheimer''s disease.
The ''prodrug'' known as JM6 works through a pathway involved in the breakdown of the amino acid tryptophan.
Washington, June 2: Scientists have discovered a new compound, which could be a potential therapy for Alzheimer''s disease.
Washington, May 31: Scientists have pinpointed a small RNA that spurs cells to manufacture a particular splice variant of a key neuronal protein, potentially promoting Alzheimer's disease (AD) or other types of neurodegeneration.
Although scientists have identified numerous proteins and RNAs that influence alternative splicing, they haven't deciphered how cells fine-tune the process to produce specific protein versions.
Washington, May 31 : Scientists have come a step closer to finding out what the causes of Alzheimer''s disease are.
Recently the number of genes known to be associated with Alzheimer''s disease has increased from four to eight, including the MS4A gene cluster on chromosome 11.
Washington, May 28 : Scientists have discovered that the increased release of stress hormones in rats leads to the generation of abnormally phosphorylated tau protein in the brain and ultimately, memory loss.
Washington, May 27: A new study has found that a family of naturally occurring plant compounds could help prevent or delay memory loss associated with Alzheimer's disease.
The study by the Translational Genomics Research Institute (TGen) showed that beta-carboline alkaloids could potentially be used in therapeutic drugs to stop, or at least slow down, the progressively debilitating effects of Alzheimer's.
Washington, May 27 : Scientists have found that the increased release of stress hormones could ultimately lead to Alzheimer's disease.
Scientists from the Max Planck Institute of Psychiatry in Munich found stress hormones in rats lead to generation of abnormally phosphorylated tau protein in the brain and ultimately, memory loss.
London, May 27 : Don't stress yourself too much, else an increased release of stress hormones could trigger Alzheimer's disease, to go by new research based on mice. Scientists from the Max Planck Institute of Psychiatry, Germany, have discovered that increased release of stress hormones in rats leads to production of excess tau protein in the brain and ultimately, memory loss.
Washington, May 25: The Feinstein Institute for Medical Research scientists have discovered that a molecule c-Abl, which has a known role in leukaemia, also has a hand in Alzheimer''s disease.
The finding offers a new target for drug development that could stave off the pathological disease process.
London, April 28 : A trial of 41 people over 60 years with mild cognitive impairment, a precursor to full-blown Alzheimer's, found that the rate of mental decline was lower in the half given 150 mg of lithium daily, compared to those given a simulated medical intervention.
While all participants showed a decline in memory function and attention tasks over the years, the rate of decline among those on lithium was significantly less.
Washington, April 28: A study led by researchers at Bay Pines VA Healthcare System and the University of South Florida has found that Cotinine, a compound derived from tobacco, reduced plaques associated with dementia and prevented memory loss in a mouse model of Alzheimer''s disease.
Washington, April 14 : Researchers from Rush University Medical Center and Massachusetts General Hospital (MGH) found that, among individuals in whom specific brain structures were thinnest, the risk of developing Alzheimer''s was three times greater than in those with above-average thickness.
