Exendin-4 significantly minimizes damage in TBI animal models

Although the death toll is relatively low for people who suffer from traumatic brain injury (TBI), it can have severe, life-long consequences for brain function. TBI can impair a patient's mental abilities, impact memory and behavior, and lead to dramatic personality changes. And long-term medical treatment carries a high economic cost.

Glia seem to play two opposing roles in protecting nerve cells from damage

A protein produced by the central nervous system's support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.

Neural protein plays two opposing roles

A protein produced by the central nervous system’s support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.

Better education early in life may help protect cognitive abilities

Exposure to solvents at work may be associated with reduced thinking skills later in life for those who have less than a high school education, according to a study published in the May 29, 2012, print issue of Neurology, the medical journal of the American Academy of Neurology.

EMA CHMP issues positive opinion to Eisai’s Fycompa for treatment of partial-onset seizures

Eisai announced today that the European Medicines Agency's Committee for Medicinal Products for Human Use (CHMP) has issued a positive opinion for the use of Fycompa (perampanel) as an adjunctive treatment of partial-onset seizures, with or without secondarily generalised seizures, in patients with epilepsy aged 12 years and older.

UCSD scientists receive new CIRM grants to conduct stem cell-based research

Five scientists from the University of California, San Diego and its School of Medicine have been awarded almost $12 million in new grants from the California Institute for Regenerative Medicine (CIRM) to conduct stem cell-based research into regenerating spinal cord injuries, repairing gene mutations that cause amyotrophic lateral sclerosis and finding new drugs to treat heart failure and Alzheimer's disease.

Hearing loss linked to several chronic diseases

The Better Hearing Institute (BHI) is raising awareness of the link between hearing loss and some chronic diseases during National Men's Health Week (June 11 – 17).

Insurance refunds in Arizona; Mass. House passes dementia care standards

Arizona consumers and businesses can expect to collect more than $36 million in refunds this summer from health-insurance companies under new provisions of the nation's health care law, according to two reports.

Immune system involved in removing Alzheimer's-causing substance in the brain

Recent work in mice suggested that the immune system is involved in removing beta-amyloid, the main Alzheimer's-causing substance in the brain. Researchers have now shown for the first time that this may apply in humans.

UCSF receives $20M Sandler Foundation gift for neuroscience research and care

UCSF has received a challenge gift of $20 million from the Sandler Foundation that will provide major support for the university's groundbreaking research and clinical care efforts regarding neurological diseases.

PERK protein necessary to maintain behavioral flexibility

Researchers have identified a protein necessary to maintain behavioral flexibility, which allows us to modify our behaviors to adjust to circumstances that are similar, but not identical, to previous experiences. Their findings, which appear in the journal Cell Reports, may offer new insights into addressing autism and schizophrenia—afflictions marked by impaired behavioral flexibility.

Scientists discover how microglia detect the site of injury

Like emergency workers rushing to a disaster scene, cells called microglia speed to places where the brain has been injured, to contain the damage by 'eating up' any cellular debris and dead or dying neurons. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now discovered exactly how microglia detect the site of injury, thanks to a relay of molecular signals.

Study sheds light on role of microglia in the normal brain

Researchers have shown in mice how immune cells in the brain target and remove unused connections between brain cells during normal development. This research, supported by the National Institutes of Health, sheds light on how brain activity influences brain development, and highlights the newly found importance of the immune system in how the brain is wired, as well as how the brain forms new connections throughout life in response to change.

Brain cells prune circuits in the brain by eating away excess synapses

We’re born with our brains prewired, but as information comes in from our environment, this circuitry is updated. A study from Boston Children’s Hospital provides a new glimpse of how this happens: Brain cells known as microglia, tuned into the crosstalk between neurons, literally engulf unnecessary connections, known as synapses, and prune them away.

Omega-3 fatty acids may provide more benefits for elderly people with Alzheimer's

According to a recent study published online in Neurology, Omega-3 fatty acids, like those found in Omega XL fish oil extract containing DHA and EPA from the New Zealand green-lipped mussel, may provide more benefits for elderly people suffering from Alzheimer's.

Brains that maintain healthy nerve connections as we age help keep us sharp in later life

Brains that maintain healthy nerve connections as we age help keep us sharp in later life, new research funded by the charity Age UK has found.

Viewpoints: The promise and perils of prostate screening; Presidential candidates shy away from frank discussion of spending

After an exhaustive process, the U.S. Preventive Services Task Force has announced its final recommendation on PSA-based prostate cancer screening. It finds that the known harms of screening outweigh the potential benefits for men who have no cancer symptoms. It notes that all screening studies have demonstrated considerable harms associated with screening, but only one major study found evidence that screening saves lives -- and that study has some internal inconsistencies.

Astrocytes appear to retaliate against AD

When brain cells start oozing too much of the amyloid protein that is the hallmark of Alzheimer's disease, the astrocytes that normally nourish and protect them deliver a suicide package instead, researchers report.

Researchers to initiate Crenezumab clinical trial to treat Alzheimer's

After an announcement by federal officials approving clinical trials for the drug Crenezumab, researchers searching for a way to treat Alzheimer's Disease are gearing up for a rare study that will allow them to test a therapy for a genetically predestined disease -- before its onset.
