Valproic acid may help slow the progression of dementia

Researchers have found that a common anticonvulsant drug improved cognitive function and appeared to restore nerve cells in the brains of patients with HIV-related dementia. The results of the Phase I clinical trial are published in the March issue of the scientific journal Neurology.

Smoking and CYP2D6 gene avert Parkinson's

It has long been known that smoking offers some protection against developing Parkinson's disease and now a Queensland University of Technology PhD researcher has found out part of the reason why.

Researchers find compound that interferes with the pathogenic effects of Huntington's disease

There is no cure for Huntington's, a neurodegenerative disorder that now afflicts 30,000 Americans, with another 150,000 at risk. The fatal disease, which is genetically inherited, usually strikes in midlife and causes uncontrolled movements, loss of cognitive function and emotional disturbance.

Potential new treatment for Huntington and Parkinson patients

A potential new treatment for neurodegenerative disorders, which seems to be able to reduce the toxic protein aggregates characteristic of many of these diseases, is published online this week in the journal Proceedings of the National Academy of Sciences.

Study looks at how two forms of vitamin E affect the health of animal cells

One of the most powerful antioxidants is truly a double-edged sword, say researchers at Ohio State University who studied how two forms of vitamin E act once they are inside animal cells.

Better tests needed for fuller view of head injuries

Concussion patients with a normal head CT scan may believe they are free of brain injury, but CT scans often miss damage at the molecular level, warns a University of Rochester Medical Center study.

Cell-death mechanism linked to developmental and degenerative brain disorders

Conclusive evidence that neurodevelopmental disorders such as mental retardation and neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease and ataxias can be caused, at least in part, by specific gene defects that interfere with the electrical impulses of rapid-firing brain nerve cells called bursting neurons.

Spinocerebellar ataxia and other neurodegenerative diseases might be treatable with drugs that alter the activity of potassium channels

For the first time, researchers have linked mutations in a gene that regulates how potassium enters cells to a neurodegenerative disease and to another disorder that causes mental retardation and coordination problems.

Engineers identify tiny iron oxide particles associated with Alzheimer's

Engineers have found a way to pinpoint and identify the tiny iron oxide particles associated with Alzheimer's and other neurodegenerative diseases in the brain.

SRY protein explains why men more likely to develop Parkinson's

Scientists at Prince Henry's Institute, Melbourne, and the University of California, Los Angeles, have discovered that SRY, the male protein that forms the testes is also produced in the brain region affected in Parkinson's disease.

SRY gene directly controls neuronal function in the brain

Shaped by much previous research, the prevailing view regarding sex-specific differences in the brain is that they are caused by circulating sex hormones, which are generated outside the brain and influence certain aspects of brain development, as well as brain function in adults.

Pig cells reverse diabetes in monkeys

A team of researchers in the U.S. have successfully reversed diabetes in monkeys using transplanted islet cells from pigs.

Thrill seekers at less risk of Parkinson's disease

According to a new study by British researchers, risk takers stand less chance of getting Parkinson's disease, live longer, and have more friends.

Research suggests that a common mechanism may underlie a variety of protein folding diseases

Misfolded and damaged proteins are common to all human neurodegenerative diseases. Clumps of these aggregated proteins destroy neurons within the brain and cause disease.

Gene therapy cures depressed mice

Researchers in the U.S. say that deleting a specific gene in the brain of mice that have been conditioned to be depressed, has the same effect as antidepressants.

Anticholinergic drugs may lead to mild mental impairment in elderly

Anticholinergic drugs may lead to mild cognitive (mental) impairment in elderly people, finds a study published online by the British Medical Journal.

HMRI researcher lights a path to understanding brain diseases

Neurologist Mike Harrington of Pasadena, California's Huntington Medical Research Institutes argues that soon we may be able to detect brain disease before symptoms even begin. The secret is in the cerebrospinal fluid, the clear liquid that cushions our brain and spinal cord.
