Multiple sclerosis (MS) may progress from the outermost layers of the brain to its deep parts, and is not always an “inside-out” process as previously thought, reported a new collaborative study from researchers at the Mayo Clinic and the Cleveland Clinic. The traditional understanding is that the disease begins in the white matter that forms the bulk of the brain’s inside, and extends to involve the brain’ ...

od maltreatment is associated with reductions in cerebral gray matter volume, and even if adolescents reporting exposure to maltreatment do not have symptoms that meet full criteria for psychiatric disorders, they may have cerebral gray matter changes that place them at risk for behavioral difficulties, according to a report in the December issue of Archives of Pediatrics & Adolescent Medicine, one of t ...

Pediatric researchers analyzing genetic influences in attention-deficit/hyperactivity disorder (ADHD) have found alterations in specific genes involved in important brain signaling pathways. The study raises the possibility that drugs acting on those pathways might offer a new treatment option for patients with ADHD who have those gene variants - potentially, half a million U.S. children. ...

In the largest study of brain development in preschoolers with autism to date, a study by UC Davis MIND Institute researchers has found that 3-year-old boys with regressive autism, but not early onset autism, have larger brains than their healthy counterparts. The study is published online today in the Proceedings of the National Academy of Sciences Early Edition. ...

Before she could seek to convince the world that her computer model of a key brain circuit explains a fundamental, 80-year-old mystery of neuroscience with potential relevance to Parkinson's disease, Stephanie Jones sought to convince Christopher Moore. The new Brown neuroscience professors are now close collaborators, but when they first started talking about the beta oscillations of the cortex, Moore thou ...

A healthy diet and the right amount of exercise are key players in treating and preventing obesity but we still know little about the relationship both factors have with each other. A new study now reveals that an increase in physical activity is linked to an improvement in diet quality. Many questions arise when trying to lose weight. Would it be better to start on a diet and then do exercise, or the other ...

As we get older, our cognitive abilities change, improving when we're younger and declining as we age. Scientists posit a hierarchical structure within which these abilities are organized. There's the "lowest" level -- measured by specific tests, such as story memory or word memory; the second level, which groups various skills involved in a category of cognitive ability, such as memory, perceptual speed, o ...

Experienced meditators seem to be able switch off areas of the brain associated with daydreaming, as well as psychiatric disorders, such as autism and schizophrenia, according to a new brain imaging study by Yale researchers. Meditation's ability to help people stay focused on the moment has been associated with increased happiness levels, said Judson A. Brewer, assistant professor of psychiatry and lead au ...

Images of prisoners’ brains show important differences between those who are diagnosed as psychopaths and those who aren’t, according to a new study led by University of Wisconsin-Madison researchers. The results could help explain the callous and impulsive anti-social behavior exhibited by some psychopaths. ...

Results from the first multi-center pilot study of deep brain stimulation (DBS) for major depressive disorder were published online today by the Journal of Neurosurgery. The study, conducted at three research facilities in Canada, was designed to replicate and build upon an earlier study by Dr. Andres Lozano and Dr. Helen Mayberg which was published in the journal Neuron in 2005. Sponsored by St. Jude Medic ...
