The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Change in sickle cell anemia prevention strategies decreases racial disparities in stroke-related deaths

The disparity in stroke-related deaths among black and white children dramatically narrowed after prevention strategies changed to include ultrasound screening and chronic blood transfusions for children with sickle cell anemia, according to research presented at the American Stroke Association's International Stroke Conference 2012.

Pediatricians lead statewide effort to raise awareness about childhood vaccination

Two Saint Louis University pediatricians are leading a Missouri State Medical Association statewide effort to change the way doctors respond to parents' fears of vaccines, and to raise awareness about the importance of getting children vaccinated.

New drug might effectively prevent clot-related strokes in patients with AF

For patients with a type of irregular heart beat called atrial fibrillation (AF), a new anti-clotting drug might be better at preventing clot-related strokes while minimizing the risk of causing a bleeding stroke.

Stryker announces results from clinical study of Trevo System on acute ischemic stroke

On February 2, at the Late-Breaking Science Session at the International Stroke Conference, Stryker announced the results of the TREVO Study (Thrombectomy REvascularization of large Vessel Occlusions in acute ischemic stroke). This was one of the first prospective, multi-center clinical studies of clot-removing stent retriever technology.

Minimally invasive technique gets rid of potentially lethal blood clots in the brain

Johns Hopkins neurologists report success with a new means of getting rid of potentially lethal blood clots in the brain safely without cutting through easily damaged brain tissue or removing large pieces of skull.

Postmenopausal women at higher risk of stroke than they think

A new study by researchers at NYU Langone Medical Center and colleagues found that traditional risk factors for stroke - such as high cholesterol - are not as accurate at predicting risk in postmenopausal women as previously thought. Instead, researchers say doctors should refocus their attention on triglyceride levels to determine which women are at highest risk of suffering a devastating and potentially fatal cardiovascular event.

International conference focuses on where and how memory is formed

The University of Haifa is hosting an international conference of leading brain researchers from around the world next week, where the participants will be attempting to answer the question of where and how memory is stored; or in less ordinary terms: "Cell and molecular mechanisms of memory formation".

Cedars-Sinai experts to present research updates at International Stroke Conference

Stroke experts from Cedars-Sinai Medical Center will present research updates at the International Stroke Conference of the American Heart Association/American Stroke Association Feb. 1 through Feb. 3 in New Orleans.

Concussions linked with number of hits received by football players

A two-year study of high school football players suggests that concussions are likely caused by many hits over time and not from a single blow to the head, as commonly believed.

Transcranial magnetic stimulation that treats depression gains momentum

A new magnetic therapy that treats major depression "is rapidly gaining momentum," said Dr. Murali Rao of Loyola University Medical Center, one of the first Chicago-area centers to offer the treatment.

Scientists uncover genes that govern male and female behaviors

Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviors that separate men from women. But how? Now a team of scientists at the University of California, San Francisco (UCSF) has uncovered many genes influenced by the male and female sex hormones testosterone and estrogen that, in turn, govern several specific types of male and female behaviors in mice.

Researchers tease out toxic role of tau oligomers in Alzheimer's

One of the most distinctive signs of the development of Alzheimer's disease is a change in the behavior of a protein that neuroscientists call tau. In normal brains, tau is present in individual units essential to neuron health. In the cells of Alzheimer's brains, by contrast, tau proteins aggregate into twisted structures known as "neurofibrillary tangles."

DNA-based prenatal blood test can also identify trisomy 13 and 18

A newly available DNA-based prenatal blood test that can identify a pregnancy with Down syndrome can also identify two additional chromosome abnormalities: trisomy 18 (Edwards syndrome) and trisomy 13 (Patau syndrome). The test for all three defects can be offered as early as 10 weeks of pregnancy to women who have been identified as being at high risk for these abnormalities.

Strong link between triglyceride levels and ischemic stroke in older women

In a surprising finding with significant implications for older women, researchers at Albert Einstein College of Medicine of Yeshiva University and NYU School of Medicine have found that high levels of triglycerides (blood fats) are the strongest risk factor for the most common type of stroke in older women – more of a risk factor than elevated levels of total cholesterol or of low-density lipoprotein (LDL) cholesterol.

Anemia triples risk of dying within a year after having a stroke

Being anemic could more than triple your risk of dying within a year after having a stroke, according to research presented at the American Stroke Association's International Stroke Conference 2012.

Version of 'Goldilocks' gene could determine future treatment for TB patients

'Goldilocks' gene could determine best treatment for TB patients Tuberculosis patients may receive treatments in the future according to what version they have of a single 'Goldilocks' gene, says an international research team from Oxford University, King's College London, Vietnam and the USA.

Researchers caution against over-reliance on CNT in return-to-play decisions

A new study by researchers at Indiana University-Purdue University Columbus and Pace University is critical of the widespread use of computerized neuropsychological tests (CNT) in decisions regarding when athletes can return to play after suffering a concussion.

Skin cells converted to brain cells without intermediate stem cell stage

Researchers from California have successfully converted mouse skin cells into cells which develop into the main components of the brain. The experiment, reported in Proceedings of the National Academy of Sciences, is notable because it skipped the middle “stem cell” stage in the process.

Assay analyzing multiple biomarkers could be valuable aid to diagnose major depression

The initial assessment of a blood test to help diagnose major depressive disorder indicates it may become a useful clinical tool. In a paper published in the journal Molecular Psychiatry, a team including Massachusetts General Hospital (MGH) researchers reports that a test analyzing levels of nine biomarkers accurately distinguished patients diagnosed with depression from control participants without significant false-positive results.
