Older people who take omega-3 fish oil supplements are probably not reducing their chances of losing cognitive function, according to a new Cochrane systematic review. Based on the available data from studies lasting up to 3.5 years, the researchers concluded that the supplements offered no benefits for cognitive health over placebo capsules or margarines, but that longer term effects are worth investigating.

STANFORD, Calif. — A team led by investigators at the Stanford University School of Medicine has found that the most common genetic risk factor for Alzheimer's disease disrupts brain function in healthy older women but has little impact on brain function in healthy, older men. Women harboring the gene variant, known to be a potent risk factor for Alzheimer's disease, show brain changes characteristic of the neurodegenerative disorder that can be observed before any outward symptoms manifest.
Teenagers with autism spectrum disorder are in a bind. The disorder is characterized by impairments in communication and social interaction, but it's a continuum, so some teens diagnosed with ASD are considered high functioning and healthy enough to be "mainstreamed" in school.
But without the proper social skills, even mainstreamed teens don't quite fit into the general social milieu of middle school or high school. As a result, they suffer from all the slings and arrows of that world.
Bethesda, MD—As science rushes to develop safe weight loss drugs, a new research report approaches this problem from an entirely new angle: What if there were a pill that would make you want to exercise harder? It may sound strange, but a new research report appearing online in The FASEB Journal suggests that it might be possible. That's because a team of Swiss researchers found that when a hormone in the brain, erythropoietin (Epo), was elevated in mice, they were more motivated to exercise.
One of the brain's jobs is to help us figure out what's important enough to be remembered. Scientists at Yerkes National Primate Research Center, Emory University have achieved some insight into how fleeting experiences become memories in the brain.
Their experimental system could be a way to test or refine treatments aimed at enhancing learning and memory, or interfering with troubling memories. The results were published recently in the Journal of Neuroscience.
(Santa Barbara, Calif.) –– You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements.
The key ingredients for a successful foster family aren't complicated, said former foster youths in a new study. Most adolescents in foster care simply need a stable home life that provides a sense of belonging, love and someone who shows a genuine interest in their lives.
But the new study, by researchers at the University of Washington, also revealed that the most common challenges in foster families included overwhelmed foster parents and a lack of trust between caregivers and foster children.
A principal standing in the hallway says, "You are one of my favorite students!" In class, a smart girl says, "You are the nicest person in our class!"
Many children would smile and eagerly return those compliments, but some with social anxiety may be too terrified to respond.
Unprofessional behavior among hospitalists is rare, but those who do behave poorly share common features, according to research published in the Journal of Hospital Medicine.
American researchers spoke to 77 Illinois hospitalists - doctors who provide care tailored to the needs of hospitalized patients as a general internist, rather than focusing on an organ, disease or a specific patient age-group.
June 12, 2012 - A father's love contributes as much — and sometimes more — to a child's development as does a mother's love. That is one of many findings in a new large-scale analysis of research about the power of parental rejection and acceptance in shaping our personalities as children and into adulthood.
Financial loss can lead to irrational behavior. Now, research by Weizmann Institute scientists reveals that the effects of loss go even deeper: Loss can compromise our early perception and interfere with our grasp of the true situation. The findings, which recently appeared in the Journal of Neuroscience, may also have implications for our understanding of the neurological mechanisms underlying post-traumatic stress disorder.
DURHAM, N.C. -- Researchers at Duke University and the National Institutes of Health have found a way to calm the fears of anxious mice with a drug that alters their brain chemistry. They've also found that human genetic differences related to the same brain chemistry influence how well people cope with fear and stress.
It's an advance in understanding the brain's fear circuitry that the research team says may hold particular promise for people at risk for anxiety disorders, including those suffering post-traumatic stress disorder (PTSD).
DARIEN, IL – The number of children with obstructive sleep apnea (OSA) declines as they enter adolescence, but the teen years can be a devastating trial of behavior and learning problems for kids with persistent OSA, new research shows.
BOSTON, MA—In the hospital it is not only direct patient care, but also the environment that contributes to recovery. A critical component of a healing environment is a peaceful space for a patient to get enough sleep.
However, according to a new study by researchers at Brigham and Women's Hospital (BWH), Massachusetts General Hospital and Cambridge Health Alliance, there are certain noises in a common hospital setting that can disrupt sleep. Such disruption can negatively affect brain activity and cardiovascular function.
MINNEAPOLIS – The American Academy of Neurology has issued an updated guideline outlining the best treatments for infantile spasms, a rare type of seizure that can occur in infants and young children. The guideline, which was co-developed with the Child Neurology Society, is published in the June 12, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology.
