BBC News (January 14, 2010): Eye Test May Detect Alzheimer's

A simple eye test might be able to detect Alzheimer's and other diseases before symptoms develop, according to UK scientists.

The technique uses fluorescent markers which attach to dying cells which can be seen in the retina and give an early indication of brain cell death.

The research has been carried out on mice, but human trials are planned.

Scientists from University College London hope this could lead to a high street opticians test for the disease.

WebMD (January 12, 2010): Hypertension Drugs May Cut Alzheimer's Risk

Drugs commonly used to treat high blood pressure and heart disease may reduce the risk of dementia and Alzheimer's disease, a new study suggests.

Boston University scientists, reporting in the journal BMJ, say a class of high blood pressure drugs called angiotensin receptor blockers is associated with a striking decrease in the risk of occurrence and progression of dementia.

The (UK) Press Association (January 12, 2010): Smell Loss Could Signal Alzheimer's

Publication Date:

Loss of a sense of smell may be an early indication of Alzheimer's disease, research suggests.

Scientists found that changes linked to the most common form of dementia begin in mice in an area of the brain responsible for recognising smells.

The physical symptoms coincided with impaired olfactory, or smell, function. Affected animals had to sniff odors for longer to remember them than healthy mice. They also had problems differentiating between smells.

People with a gene linked to long life and good health are also less likely to develop Alzheimer's disease, U.S. researchers said on Tuesday.

They said people with two copies of a certain version of the cholesteryl ester transfer protein or CETP gene had significantly slower memory declines compared with people who had different versions of the gene.

Science Daily (January 12, 2010): New Compound Improves Cognitive Decline, Symptoms of Alzheimer's Disease in Rodents

Publication Date: 
Tue, 01/12/2010

A fast-acting compound that appears to improve cognitive function impairments in mice similar to those found in patients with progressive Alzheimer's disease has been identified by scientists at Wake Forest University School of Medicine and the Vanderbilt University Medical Center Program in Drug Discovery. Researchers hope to one day replicate the result in humans.

Science Daily (January 11, 2010): Neuroimaging May Shed Light on How Alzheimer's Disease Develops

Publication Date: 
Mon, 01/11/2010

Current Alzheimer's Disease (AD) research indicates that accumulation of amyloid-beta (Aβ) protein plaques in the brain is central to the development of AD. Unfortunately, presence of these plaques is typically confirmed only at autopsy. In a special issue of the journal Behavioral Neurology, researchers review the evidence that positron emission tomography (PET) can image these plaques during life. This exciting new technique provides researchers with an opportunity to test the amyloid hypothesis as it occurs in living patients.

The Harvard Crimson (January 8, 2010): Unequal Distribution of Assisted Living Homes Hint at Problems, Study Says

Elderly assisted-living facilities are disproportionally located in more affluent areas, with Massachusetts lagging far behind other states in terms of the number of assisted-living units available, according to a recent Harvard Medical School study.

Boston Globe (January 7, 2010): 2-Track Therapy Shows Promise in Study of Alzheimer's in Mice

Publication Date: 
Thu, 01/07/2010

Alzheimer's disease may be better treated with a cocktail of therapies that limit production of the plaque that impairs the brain rather than with a single treatment, a study in mice suggests.

The combination approach preserved memory with few side effects, something individual treatment methods haven't been able to do as well, researchers at Johns Hopkins University School of Medicine said in a report published yesterday in the journal Science Translational Medicine.

Science Daily (January 6, 2010): New Brain Scan Better Detects Earliest Signs of Alzheimer's Disease in Healthy People

Publication Date: 
Wed, 01/06/2010

A new type of brain scan, called diffusion tensor imaging (DTI), appears to be better at detecting whether a person with memory loss might have brain changes of Alzheimer's disease, according to a new study published in the January 6, 2010, online issue of Neurology, the medical journal of the American Academy of Neurology.

National Geographic News (January 6, 2010): Cell Phone Use May Fight Alzheimer's, Mouse Study Says

Publication Date: 
Wed, 01/06/2010

Microwave radiation from cell phones may protect against and even reverse Alzheimer's-like symptoms, according to a new study involving genetically-tweaked mice.

The results were so surprising that study co-author Juan Sanchez-Ramos didn't believe them at first.

"It's such a dramatic and counterintuitive effect," said Sanchez-Ramos, a Unverisity of Florida neuroscientist.

"I joked that the animals must have been mislabeled or that the power wasn't switched on."
