NIH takes another shot at studying environment, child health The National Institutes of Health is launching a new project to help unravel how early-in-life environmental exposures may affect autism, obesity and certain other childhood disorders.
HIV to depression: New medical guidelines for kids Pediatricians release updated guidelines for children's medical screening.
Can light therapy treat non-seasonal depression too? Experts say light therapy could be a new treatment option for depression, either on its own or with medication.
Enhancing neuroplasticity: Study suggests physical activity makes it easier for the brain to change Learning, memory, and brain repair depend on the ability of our neurons to change with experience. Now, researchers reporting in the Cell Press journal Current Biology on December 7 have evidence from a small study in people that exercise may enhance this essential plasticity of the adult brain. The findings focused on the visual cortex [...]
Pharmaceutical cannabidiol shows promise for children with severe epilepsy Around the globe there is high interest in the use of cannabidiol (CBD), a type of cannabinoid, for the treatment of people with epilepsy, especially children who have treatment-resistant forms of the disorder such as Lennox-Gastaut Syndrome (LGS) and Dravet Syndrome (DS). Three studies presented at the American Epilepsy Society’s 69th Annual Meeting in Philadelphia [...]
A supplement for myelin regeneration Multiple sclerosis patients continually lose the insulating myelin sheath that wraps around neurons and increases the speed of impulses in the central nervous system. Whenever neurons are demyelinated, OPCs migrate toward these cells and differentiate into mature, myelin-producing oligodendrocytes, but this process becomes less and less effective as people age. A nuclear receptor protein called [...]
Negative beliefs about aging predict Alzheimer’s disease Newly published research led by the Yale School of Public Health demonstrates that individuals who hold negative beliefs about aging are more likely to have brain changes associated with Alzheimer’s disease. The study suggests that combatting negative beliefs about aging, such as elderly people are decrepit, could potentially offer a way to reduce the rapidly [...]
Chomsky was right, researchers find: We do have a ‘universal grammar’ in our head A team of neuroscientists has found new support for MIT linguist Noam Chomsky’s decades-old theory that we possess an “internal grammar” that allows us to comprehend even nonsensical phrases. “One of the foundational elements of Chomsky’s work is that we have a grammar in our head, which underlies our processing of language,” explains David Poeppel, [...]
Testosterone-lowering therapy for prostate cancer may increase Alzheimer’s risk Men taking androgen deprivation therapy (ADT) for prostate cancer were almost twice as likely to be diagnosed with Alzheimer’s disease in the years that followed than those who didn’t undergo the therapy, an analysis of medical records from two large hospital systems by Penn Medicine and Stanford University researchers has shown. Men with the longest [...]
Study explains why men tend to have a better sense of direction than women It’s been well established that men perform better than women when it comes to specific spatial tasks. But how much of that is linked to sex hormones versus cultural conditioning and other factors? Researchers at the Norwegian University of Science and Technology (NTNU) decided to explore this idea by administering testosterone to women and testing [...]
Parkinson’s disease research puts designer dopamine neurons within reach For decades, the elusive holy grail in Parkinson’s disease research has been finding a way to repair faulty dopamine neurons and put them back into patients, where they will start producing dopamine again. Researchers have used fetal material, which is difficult to obtain and of variable quality. Embryonic stem cells represented a tremendous innovation, but [...]
New algorithm helps scientists analyze neuron images Scientists looking for ways to stimulate the growth of neurons can spend hours painstakingly analyzing microscope images of cells growing in petri dishes. A new algorithm developed by Brown University researchers automates that process and analyzes images more accurately than previous automated approaches. The algorithm and an initial round of testing are described in Nature [...]
Home-delivered meals reduce loneliness, study finds When Congress passed the Older Americans Act in 1965 to support elderly people who were struggling — often alone — to continue to live at home, a major plank of the legislation provided for home delivery of meals to ensure their adequate nutrition. In the midst of the holiday season, a newly published study confirms [...]
Liking or not liking babies linked with testosterone responses to sexual stimuli in young men Young men’s interest in babies is associated with their physiological reactivity to sexually explicit material, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The study showed that young men who reported more interest in babies showed a lower increase in testosterone in response to sexually explicit material [...]
Study: Critical periphery of ‘slacktivists’ greatly amplify a movement’s message You know them well. You might even be one of them. They’re the people who tint their Facebook profile pictures with the French flag to support Parisians, or pink to get behind Planned Parenthood. They sign online petitions, share activist videos, and retweet celebrities who take a political stand. They’re willing to lift a finger [...]
How our brains overrule our senses: Experiments reveal brain circuits that shape perceptions Scientists have long known that when sounds are faint or objects are seen through fog in the distance, repetition of these weak or ambiguous sensory ‘inputs’ can result in different perceptions inside the same brain. Now the results of new research, described online Dec. 7 in the journal Nature Neuroscience, have identified brain processes in [...]
Mindfulness-based stress reduction diminishes chemo brain Participation in a mindfulness-based stress reduction program yields robust and sustained improvement in cancer-related cognitive impairment, a prevalent and potentially debilitating condition that affects attention, memory and executive function in survivors, according to a new study from the Regenstrief Institute and Indiana University School of Medicine. Although cancer-related cognitive impairment, sometimes referred to as chemo [...]
