Alzheimer's Disease News and Research

RSS

Alzheimer's disease (AD) is an irreversible, progressive brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living. In most people with AD, symptoms first appear after age 60. AD is the most common cause of dementia among older people, but it is not a normal part of aging. Dementia refers to a decline in cognitive function that interferes with daily life and activities. AD starts in a region of the brain that affects recent memory, then gradually spreads to other parts of the brain. Although treatment can slow the progression of AD and help manage its symptoms in some people, currently there is no cure for this devastating disease.

Latinos and African Americans with Alzheimer's live longer than white people with the disease

Latinos and African Americans with Alzheimer's disease live longer than white people who have the disease, according to a study published November 14, 2007, in the online edition of Neurology, the medical journal of the American Academy of Neurology.

New drug may restore memory with Alzheimer's disease

A 2006 study by MetLife found that adults over age 55 fear Alzheimer's disease more than cancer, and with good reason. Alzheimer's creeps up on patients and their families, robbing more than half of all Americans over age 85 of their memory and ability to care for themselves.

Research looks at how environment inside a living cell affects protein structure

The syrupy soup of proteins, ribosomes and membranes inside a living cell is so tightly packed it may increase the structural content of proteins by as much as 25 percent, according to new research from Rice University and the University of Houston (UH).

New insights into cataracts

Using the tools and techniques of soft condensed matter physics, a research team in Switzerland has demonstrated that a finely tuned balance of attractions between proteins keeps the lens of the eye transparent, and that even a small change in this balance can cause proteins to aggregate and de-mix.

Overexpression of neuroglobin reduces severity of Alzheimer's disease in mice

Mice genetically engineered to both overproduce the protein neuroglobin and to develop Alzheimer's disease (AD) had a much milder form of the disease when compared to mice engineered to have AD alone, researchers at the Buck Institute for Age Research have reported.

Tiny fluorescent probes illuminate protein interactions in living cells

While fluorescence has long been used to tag biological molecules, a new technology developed at Yale allows researchers to use tiny fluorescent probes to rapidly detect and identify protein interactions within living cells while avoiding the biological disruption of existing methods, according to a report in Nature Chemical Biology.

Omega-3 rich oils lower risk of memory problems, omega-6 rich oils may increase risk

A diet rich in fish, omega-3 oils, fruits and vegetables may lower your risk of dementia and Alzheimer's disease, whereas consuming omega-6 rich oils could increase chances of developing memory problems, according to a study published in the November 13, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

Could a new vaccine be the key to stopping Alzheimer's disease?

A new study from the Oklahoma Medical Research Foundation (OMRF) shows that immunization could offer a way to blunt or even prevent the deadly, memory-robbing disease.

Ageing exhibition reveals scientists' plans for lifelong health

The UK population is rapidly getting older: a predicted 1 in 4 people will be over the age of 65 by 2031. Ensuring that an increasingly ageing population stays healthy and mobile is a challenge for both the Government and the scientific research community.

False memory syndrome

Duke University Medical Center neuroscientists say the places a memory is processed in the brain may determine how someone can be absolutely certain of a past event that never occurred.

Your Apo E genotype plays part in likelihood of Alzheimer's and heart disease

We all carry the Apo E gene. It plays a key role in the development of Alzheimer's Disease and heart disease, along with a host of chronic ailments.

Prazosin curbs brain damage from post-traumatic stress disorder

A drug used to treat high blood pressure and enlargement of the prostate may protect the brain from damage caused by post-traumatic stress disorder, Alzheimer's disease, depression and schizophrenia.

Maternal link to Alzheimer's disease found

People who have a mother with Alzheimer's disease appear to be at higher risk for getting the disease than those individuals whose fathers are afflicted, according to a new study by NYU School of Medicine researchers.

Link between statins and cognitive decline a complex one

Previous explorations of a link between statins, a cholesterol lowering medication, and cognitive decline have produced inconsistent results.

Hypertension or atrial fibrillation linked to Alzheimer's disease progression

Alzheimer's disease (AD) may progress more rapidly in people with high blood pressure or a form of irregular heartbeat, atrial fibrillation, according to results of a Johns Hopkins study published in the Nov. 6, 2007, issue of Neurology.

Children with apoE4 gene show reduced cognitive function

Children who possess a gene known to increase the risk of Alzheimer's disease already show signs of reduced cognitive function, an Oregon Health & Science University study has found.

PET scan distinguishes Alzheimer's from other dementia

A PET scan (positron emission tomography) that measures uptake of sugar in the brain significantly improves the accuracy of diagnosing a type of dementia often mistaken for Alzheimer's disease, a study led by a University of Utah dementia expert has found.

Merck Serono and EPFL announce neuroscience, oncology and drug delivery partnership

Merck Serono, a division of Merck KGaA, and EPFL (Ecole Polytechnique Fédérale de Lausanne), one of the two Swiss Federal Institutes of Technology, announced the signing of a research collaboration agreement in the areas of Neuroscience, Oncology and Drug Delivery. Under this agreement, three Merck Serono-endowed Chairs will be created at EPFL: in neurodegenerative diseases, such as Alzheimer's and Parkinson's; in cancer, in the framework of the Swiss Institute for Experimental Cancer Research (ISREC); and in innovative drug delivery technologies, for instance nanoparticle vaccines.
