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.

Low doses of bisphenol–A (BPA) can impair brain function

Low doses of the environmental contaminant bisphenol–A (BPA), widely used to make many plastics found in food storage containers, including feeding bottles for infants, can impair brain function, leading to learning disabilities and age–related neurodegenerative diseases, according to Yale researchers and colleagues.

Tissue engineering to grow bone, ligaments and cartilage

A future in which laboratory-grown organs and stimulated growth of muscle, bones and nerves could play a major role in treating medical conditions was revealed at a recent Tissue Engineering Symposium at Wake Forest University Baptist Medical Center.

The liver may produce most of the body's good cholesterol

Research in mice suggests that the liver may produce most of the body's "good" cholesterol, an unexpected finding that might one day help scientists develop new treatments to raise levels of this heart-protecting molecule in humans.

Researchers shed light on the brain cell damage caused by Alzheimer's disease

The researchers hope that by gaining a better understanding of the disease's cellular impacts, progress can be made towards developing a treatment. The research is reported in the current edition of the Journal of Alzheimer's Disease, published by IOS publishers.

Why different tissues in the human body vary in their susceptibility to "amyloid" diseases

Researchers at The Scripps Research Institute are reporting the results of a recent study that addresses why different tissues in the human body vary in their susceptibility to "amyloid" diseases, which include Alzheimer's disease and a cluster of ailments called the familial amyloidoses.

Osteoporosis drug reduces women's risk of mild cognitive impairment

A drug prescribed for the prevention of osteoporosis reduced women's risk of mild cognitive impairment by 33 percent in a worldwide clinical trial led by researchers at San Francisco VA Medical Center (SFVAMC).

Blue-green algae linked to Alzheimer's disease

An international team of researchers, including scientists from the University of Dundee have announced that cyanobacteria (blue-green algae) found throughout the world may produce a toxin linked to certain types of neurological disease.

Light therapy effectively treats mood disorders

A study commissioned by the American Psychiatric Association and led by a psychiatrist at the University of North Carolina at Chapel Hill School of Medicine has found that light therapy effectively treats mood disorders, including seasonal affective disorder (SAD) and other depressive disorders.

Potential therapeutic role for the ataxin-3 protein for Machado-Joseph disease

The repetition of three little "letters" within the gene that codes for the ataxin-3 protein is both the cause of and perhaps a solution to Machado-Joseph disease and an entire family of similar genetic disorders, according to researchers at the University of Pennsylvania.

Sea floor may yield disease cures

On Monday, the Harbor Branch drug discovery group will begin a 2-week expedition to explore the Straits of Florida in search of organisms that produce chemicals with the potential to cure diseases such as cancer and Alzheimer's.

Fish is brain food

Researchers with the Department of Veterans Affairs (VA) and the University of California at Los Angeles (UCLA) found that a diet high in docosahexenoic acid, or DHA--an omega-3 fatty acid found in relatively high concentrations in cold-water fish--dramatically slowed the progression of Alzheimer's disease in mice.

Docosahexaenoic acid may protect against the accumulation of a protein believed to be linked to Alzheimer's disease

Docosahexaenoic acid (DHA), an omega-3 fatty acid, may protect against the accumulation of a protein believed to be linked to Alzheimer's disease, according to the results of a new study published in the March 30, 2005 issue of The Journal of Neuroscience. The study used Martek DHA, which is produced from microalgae.

Alzheimer's treatment improves with new diagnostic method

Earlier detection and treatment for Alzheimer's Disease are now more practical for larger segments of the population through a more refined use of existing, well-validated neuropsychological tests.

Neuronal death and processing of Tau protein in Alzheimer’s Disease (AD)

In a research report recently published in the Journal of Alzheimer's Disease, published by IOS Press, a research group from the International School for Advanced Studies (ISAS\SISSA) in Trieste (Luisa Fasulo, Gabriele Ugolini e Antonino Cattaneo) showed that a processed form of tau protein induces neuronal death by apoptosis (programmed cell death) when expressed in cultured rat hippocampal neurons.

Decision to cut Alzheimer's drugs challenged

Four major drugs, the only drugs licensed in Britain for the treatment of Alzheimer's disease and available on the NHS may be withdrawn. Aricept, Exelon, Reminyl and Ebixa are the only drugs licensed in Britain for the treatment of the disease.

College in retirement helps stave off mental decline

A new study from the University of Toronto helps explain why higher education appears to slow down cognitive decline as people age. It seems possible that education strengthens the ability to "call in the reserves" of mental prowess.

New twist on the role that estrogens play in the development of behavioral differences between men and women

What makes a man behave like a man and a woman a woman? The answer may be partly in your genes. Researchers at the University of Virginia Health System have discovered a new twist on the role that estrogens play in the development of behavioral differences between males and females.

High-dose radiation and bone marrow transfer treatments on glaucoma-susceptible mice completely blocked development of glaucoma

In a discovery that could point to new treatments for a wide range of neurodegenerative diseases, Jackson Laboratory researchers have found that high-dose radiation and bone marrow transfer treatments on glaucoma-susceptible mice completely blocked the development of glaucoma, by preventing neurodegeneration.

Active brains stave off Alzheimer's signs

Mice who keep busy playing with toys also keep their brains and bodies active; more importantly, they also have lower levels of the peptides and brain plaques associated with Alzheimer's disease, compared to mice raised in environments not "enriched" with chew toys, running wheels,and tunnels, according to a new study in the 11 March issue of the journal Cell.
