New Cholesterol gene linked to Alzheimer's

...riant revealed significantly higher levels of beta amyloid deposits than those without the variant. Dr. Benjamin Wolozin of Loyola University Medical Center in Maywood, said in an accompanying editorial that this and earlier studies suggest that inhibiting cholesterol breakdown in the brain might represent ...

Lithium May help in Alzheimer's Disease

...by the buildup in the brain of one protein, called amyloid beta, outside nerve cells and a second, called tau.... Many scientists believe that the accumulation of amyloid beta causes the debilitating effects of the memory-robbing disease. The recent issue of the jour...

Key enzyme protects against Alzheimer's

...ave been diagnosed with the illness. A build-up of amyloid plaque and tangles of a protein called tau cause the incurable progressive illness that robs people of their memory and mental ability. In studies of transgenic mice which lacked the Pin1 gene, the scientists also discovered that the deletion of th...

They had followed up the patients for 22 months and found no side effects or adverse reactions in them. Scientists had used Mini...

Alzheimer’s vaccine may be a reality soo

...ccine aims at stimulating an immune attack on beta amyloid without any threat of brain inflammation. The results from the interrupted tests show that there had been significant increase in memory retention by patients who have received the vaccine against those who received the placebo. Researchers feel tha...

Fish is good for Alzheimer's patients

... were fed food with DHA had a 70% less build up of amyloid protein in their brain. This happened after a period of three to five months of feeding them the fortified chow. When taken as equivalent to human life, this will approximate to about a few years of human life. Amyloid protein build up in the brain ...

The 'bitter' proteins

...genic mice that produce two human proteins – human amyloid precursor protein (hAPP) and human alpha-synuclein (hSYN).Of the two proteins, hAPP is linked with Alzheimer’s and hSYN with Parkinson’s; and mice that produce one of these proteins develop the symptoms of the associated disease. The researchers di...

Researchers Identified Process That Aids Spread Of Alzheimer’s’ Diseae

...odged in the cell’s membrane, including one called amyloid precursor protein, or APP. Nicastrin then guides membrane-bound proteins to the active area of gamma-secretase, which then splits the proteins. APP, for example, is chopped into two parts: amyloid-beta, which is then shipped to the outside of the cel...

Number Of Dementia Cases To Rise Drastically

...lzheimer's disease is believed to be caused by the amyloid beta protein plaques building up within the brain. The mental functions can be preserved through adopting a healthy lifestyle which involves both physical and mental activity. ...

Obesity could lead to Alzheimer's

...er for obese people. In fact, heightened levels of amyloid in the blood vessels and the brain indicate the start of the Alzheimer's process. Dr Gandy and his colleagues measured the body mass index and beta-amyloid levels in the blood. They also looked at several other factors associated with heart diseas...

Alzheimer's Can Be Slowed Down By Gold Nanoparticles

...sts attached gold nanoparticles to a group of beta amyloid fibrils, incubated the resulting mixture for several days and then exposed it to weak microwave fields for several hours. The energy levels of the fields were six times smaller than that of conventional cell phones and unlikely to harm healthy cells....

Experimental Alzheimer’s Drug curbs the disease in mic

...e in mice. This compound (AF267B) curbs both the amyloid protein plaques that collect in Alzheimer's-affected brains, as well as another lesion, the tangles of protein called tau. In mice that have been genetically designed to mimic Alzheimer's disease AF267B also appears to reverse cognitive declines. R...
