Alzheimer's gene slows brain's ability to export toxic protein

The only known genetic risk factor for Alzheimer's disease slows down the brain's ability to export a toxic protein known as amyloid-beta that is central to the damage the disease causes, scientists have found.

Hope for treating relapse to methamphetamine abuse

"Reinstatement of drug-seeking behavior after an extended period of abstinence is the number-one cause of drug-addiction relapse," said Brookhaven neuroanatomist Stephen Dewey, who led the research team. "This animal study suggests that vigabatrin could potentially prevent human methamphetamine addicts from relapsing."

Breakthrough in cell-type analysis offers new ways to study development and disease

Like skilled assassins, many diseases seem to know exactly what types of cells to attack. While decimating one cadre of cells, diseases will inexplicably spare a seemingly identical group of neighbors. What makes cells vulnerable or not depends largely on the kinds and amounts of proteins they produce - their 'translational profile,' in the lingo of molecular biology. For this reason, scientists have struggled to parse the subtle molecular differences among the hundreds of specialized cell types that are tangled together in tissues like the brain.

Discovery of unique approach for delivering drugs to the brain - potential for Alzheimer's and stroke

Saint Louis University researchers have identified a novel way of getting a potential treatment for Alzheimer's disease and stroke into the brain where it can do its work.

Isoflurane induces Alzheimer's-associated changes in mouse brains

For the first time researchers have shown that a commonly used anesthetic can produce changes associated with Alzheimer's disease in the brains of living mammals, confirming previous laboratory studies.

Novel tool helps study the biochemical basis of Alzheimer's

A new study being published in this Friday's online edition of Cell will help answer the question, what causes Parkinson's disease?

Researchers uncover beneficial mechanism of the helpful "Dr. Jekyll" side of the Cdk5 protein

Researchers at UT Southwestern Medical Center have uncovered new insights into the "Dr. Jekyll and Mr. Hyde" nature of a protein that stimulates stem-cell maturation in the brain but, paradoxically, can also lead to nerve-cell damage.

All stem cells are not created equal, explains expert

During the course of the Presidential campaign, Obama signaled his intention to reverse Bush's controversial limit on federal funding of embryonic stem cell research.

Raptor Pharmaceuticals announces positive results for Convivia program

Raptor Pharmaceuticals Corp. has announced positive results in its Phase IIa study of oral 4-methylpyrazole ("4-MP") in subjects with ALDH2 deficiency, or ethanol intolerance, as the initial development stage of its Convivia program.

Researchers describe how cells recycle protein waste

Garbage collectors are important for removing trash; without them waste accumulates and can quickly become a health hazard.

One in five U.S. hospital admissions are for patients with mental disorders

According to the latest figures from the Agency for Healthcare Research and Quality (AHRQ) in the United States, one in five hospital admissions are for patients with mental disorders.

Education delays onset of the dementia

A test that reveals brain changes believed to be at the heart of Alzheimer's disease has bolstered the theory that education can delay the onset of the dementia and cognitive decline that are characteristic of the disorder.

Greater thinking, learning and memory abilities delay symptoms of Alzheimer's disease

Individuals with higher education levels appear to score higher on cognitive tests despite having evidence of brain plaques associated with Alzheimer's disease, according to a report in the November issue of Archives of Neurology , one of the JAMA/Archives journals.

Education lessens the effects of Alzheimer's

The scientists from the Washington University School of Medicine, St. Louis, say their research supports the 'cognitive reserve' hypothesis and individuals with levels of higher education levels score higher on cognitive tests despite having Alzheimer's disease.

Study finds 25% of family caregivers of AD patients go to ER or are hospitalized

One quarter of all family caregivers of Alzheimer's disease patients succumb to the stress of providing care to a loved one and become hospital patients themselves, according to an Indiana University study published in the November 2008 issue of the Journal of General Internal Medicine.
