Research pinpoints antibodies that may prevent Alzheimer's

Antibodies to a wide range of substances that can aggregate to form plaques, such as those found in Alzheimer's patients, have been identified in the blood and cerebrospinal fluid of healthy people. Levels of these antibodies decline with age and, in Alzheimer's patients, with increasing progression of the disease.

Delirium in hospitalized adults: Situation critical, no relief available

Every year as many as seven million adults in the United States experience delirium during hospitalization. In a systematic review of the scientific literature on delirium prevention and treatment, investigators from the Regenstrief Institute, Indiana University, and Wishard Health Services found that despite the significant health and financial burdens of delirium for hospitalized adults, no effective way to prevent or treat the condition has been identified.

The single life can increase some people's dementia risk

The researchers from the Karolinska Institute suggest that people who have a particular gene variation and live alone in middle-age, have a higher risk of developing dementia.

New pieces in the autism inheritance puzzle

Pieces in the complex autism inheritance puzzle are emerging in the latest study from a research team including geneticists from the University of Pennsylvania School of Medicine and The Children's Hospital of Philadelphia (CHOP). The study identified 27 different genetic regions where rare copy number variations - missing or extra copies of DNA segments - were found in the genes of children with autism spectrum disorders, but not in the healthy controls. The findings are published June 26 in the open-access journal PLoS Genetics.

Recent trends in breast cancer incidence in U.S. white women by urban/rural and poverty status

The recent decline in invasive breast cancer in the US was significantly less pronounced in the poor and those who live in rural areas. Researchers writing in the open access journal BMC Medicine suggest this may be due to varying reductions in the numbers of women taking hormone therapy (HT).

Even moderate exercise helps keep the brain healthy

Scientists at the University of Queensland (UQ) say they have found that exercise helps keep the brain healthy and even moderate exercise directly increases the number of stem cells in the ageing brain.

Heart attacks kill 10,000 Australians each year and many could be avoided

A new report by Access Economics has revealed that this year 80,000 Australians can expect to be treated in hospital for heart attacks or chest pain - at a cost to the economy of $18 billion and 10,000 people will die from a heart attack.

Cognitive health among seniors in the United States and in England

American over-65s scored significantly better than their English counterparts at a memory and awareness test. The authors of the research, published in the open access journal BMC Geriatrics, suggest that differences in relative levels of depression, education, and the aggressiveness of treatment for heart disease may be to blame.

Underweight and extremely obese die earlier

Underweight people and those who are extremely obese die earlier than people of normal weight - but those who are overweight actually live longer than people of normal weight.

Researchers to reveal the underlying causes of ageing

Four of the biologists who described the underlying causes of aging will soon share their findings with an international audience during a symposium at the upcoming World Congress of Gerontology and Geriatrics, taking place from July 5-9, 2009, in Paris, France.

Migraines with aura in middle age associated with late-life brain lesions

Women who suffer from migraine headaches in middle age accompanied by neurological aura (visual disturbances, dizziness or numbness that can precede migraines) are more likely to have damage to brain tissue in the cerebellum later in life, according to a study by researchers at the National Institute on Aging (NIA) of the National Institutes of Health, the Uniformed Services University of the Health Sciences and the Icelandic Heart Association in Reykjavik.

Women warned not to wait too long to have a baby

Women are being warned that they should consider starting a family before the age of 35 or they will risk missing out on motherhood.

Omega-3 fatty acids may protect against progression of age-related macular degeneration

Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration (AMD), but the benefits appear to depend on the stage of disease and whether certain supplements are taken, report researchers at the Laboratory for Nutrition and Vision Research (LNVR), Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University.

Increased risk of stroke and transient ischemic attack in survivors of Hodgkin lymphoma

Patients treated for Hodgkin lymphoma with radiation therapy have a substantially higher risk of stroke, according to a new study published June 17 online in the Journal of the National Cancer Institute.

“Life force” linked to body’s ability to withstand stress

Our ability to withstand stress-related, inflammatory diseases may be associated, not just with our race and sex, but with our personality as well, according to a study published in the July issue of the journal Brain, Behavior and Immunity. Especially in aging women, low levels of the personality trait extraversion may indicate that blood levels of a key inflammatory molecule have crossed over a threshold linked to a doubling of risk of death within five years.

New diagnostic technique detects possible Alzheimer's biomarker in blood

A new diagnostic technique which may greatly simplify the detection of Alzheimer's disease has been discovered by researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital (JGH).

Simple blood test detects molecular marker of aging in humans

In 2004, researchers at the University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center announced a crucial discovery in the understanding of cellular aging. They found that as cells and tissues age, the expression of a key protein, called p16INK4a, dramatically increases in most mammalian organs. Because p16INK4a is a tumor suppressor protein, cancer researchers are interested in its role in cellular aging and cancer prevention.

Preventing spread of infectious diseases is everyone’s responsibility – and everyone’s job

According to a report published today, we must all share responsibility for preventing the spread of diseases such as swine flu, SARS, avian influenza, diarrhoeal and skin diseases, and even the common cold.
