Researchers find link between low cognitive score and risk of brain injury

It is estimated that there are 10 million cases of traumatic brain injury globally every year with mild traumatic brain injuries being responsible for 70-90% of these. Incidence is highest among young males.

Current literature suggests that mild traumatic brain injuries cause changes in brain tissues and have important long-term consequences on cognitive function. Deficits have been described in attention, memory, verbal learning and processing speed and may occur in 15-25% of those suffering one of these injuries.

Using fat to fight brain cancer

In laboratory studies, Johns Hopkins researchers say they have found that stem cells from a patient's own fat may have the potential to deliver new treatments directly into the brain after the surgical removal of a glioblastoma, the most common and aggressive form of brain tumor.

Study: Brain imaging after mild head injury/concussion can show lesions

SAN DIEGO – Brain imaging soon after mild traumatic brain injury (mTBI) or mild concussion can detect tiny lesions that may eventually provide a target for treating people with mTBI, according to a study released today and that will be presented at the American Academy of Neurology's 65th Annual Meeting in San Diego, March 16 to 23, 2013.

'I don't want to pick!' Preschoolers know when they aren't sure

Children as young as 3 years old know when they are not sure about a decision, and can use that uncertainty to guide decision making, according to new research from the Center for Mind and Brain at the University of California, Davis.

Autistic children may be at greater risk of suicide ideation and attempts

Children with an autism spectrum disorder may be at greater risk for contemplating suicide or attempting suicide than children without autism, according to Penn State College of Medicine researchers.

"We were looking at suicidal ideation and suicide attempts among children with autism versus those that didn't have autism," said Angela Gorman, assistant professor of child psychiatry, Penn State College of Medicine. "What we found is that there were some risk factors that were much more greatly associated with suicidal ideation and suicide attempts than others."

Computer model may help athletes and soldiers avoid brain damage and concussions

Concussions can occur in sports and in combat, but health experts do not know precisely which jolts, collisions and awkward head movements during these activities pose the greatest risks to the brain. To find out, Johns Hopkins engineers have developed a powerful new computer-based process that helps identify the dangerous conditions that lead to concussion-related brain injuries. This approach could lead to new medical treatment options and some sports rule changes to reduce brain trauma among players.

Neural 'synchrony' may be key to understanding how the human brain perceives

Despite many remarkable discoveries in the field of neuroscience during the past several decades, researchers have not been able to fully crack the brain's "neural code." The neural code details how the brain's roughly 100 billion neurons turn raw sensory inputs into information we can use to see, hear and feel things in our environment.

Updated 'stereo EEG' workflow simplifies planning of epilepsy surgery

Philadelphia, Pa. (March 12, 2013) – For patients with "drug-resistant" epilepsy requiring surgery, an updated stereoelectroencephalography (SEEG) technique provides a more efficient process for obtaining critical data for surgical planning, according to a study in the March issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Ruptured aneurysm has lasting impact on quality of life

Philadelphia, Pa. (March 12, 2013) – Ten years after stroke caused by a ruptured aneurysm of the brain, surviving patients have persistent difficulties in several areas affecting quality of life, reports a study in the March issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Tickling the brain with magnetic stimulation improves memory in schizophrenia

Philadelphia, PA, March 12, 2013 – Cognitive impairments are disabling for individuals with schizophrenia, and no satisfactory treatments currently exist. These impairments affect a wide range of cognition, including memory, attention, verbal and motor skills, and IQ. They appear in the earliest stages of the disease and disrupt or even prevent normal day-to-day functioning.

Infants prefer individuals who punish those not like themselves, Yale researchers find

Infants as young as nine months old prefer individuals who punish those who are not like them, and this seemingly innate mean streak grows stronger in the next five months of life, a study by researchers at Yale University has found.

Low T3 syndrome predicts unfavorable outcomes in surgical patients with brain tumor

Charlottesville, VA (March 12, 2013). In a study of 90 patients undergoing surgery for brain tumor, researchers in Lithuania (Lithuanian University of Health Sciences) and the United States (University of North Carolina at Chapel Hill and Brigham & Women's Hospital, Harvard University) have discovered that the finding of low T3 (triiodothyronine) syndrome is predictive of unfavorable clinical outcomes and depressive symptoms.

Children who avoid scary situations likelier to have anxiety, Mayo Clinic research finds

ROCHESTER, Minn. -- Children who avoid situations they find scary are likely to have anxiety a Mayo Clinic study of more than 800 children ages 7 to 18 found. The study published this month in Behavior Therapy presents a new method of measuring avoidance behavior in young children.

Sleep discovery could lead to therapies that improve memory

RIVERSIDE, Calif. — A team of sleep researchers led by UC Riverside psychologist Sara C. Mednick has confirmed the mechanism that enables the brain to consolidate memory and found that a commonly prescribed sleep aid enhances the process. Those discoveries could lead to new sleep therapies that will improve memory for aging adults and those with dementia, Alzheimer's and schizophrenia.

The groundbreaking research appears in a paper, "The Critical Role of Sleep Spindles in Hippocampal-Dependent Memory: A Pharmacology Study," published in the Journal of Neuroscience.

Friend or foe: Babies choose sides early

Babies have a dark side under their cute exteriors, according to University of British Columbia-led study that finds infants as young as nine months embrace those who pick on individuals who are different from them.

While previous research has shown that babies generally prefer kind actors, the new study – published by the Association for Psychological Science – is the first to suggest that infants condone antisocial behavior when it is directed at individuals who are dissimilar.
