Study: Energy drinks possibly linked to ADHD in children

Kids, beware: A new Yale research study has found a possible link between energy drinks and ADHD in middle school children. Out of the 1,649 middle school students surveyed, those who drank beverages high in sugar and caffeine were 66 percent more likely to have symptoms of hyperactivity and inattention. The study found that boys …

Why Reading On A Screen Is Bad For Critical Thinking

“Think fast!” As kids, that’s what we used to say at school recess when tossing the ball around. Is “Think fast!” what we’re now saying when we read? Historically, thinking and reading have gone hand-in-hand. Eric Havelock argued years back that development of alphabetic writing in Greece enabled a level of analysis not earlier possible. …

The connections in autistic brains are idiosyncratic and individualized

Each autistics’ brain is distinct; non-autistics’ brains are remarkably uniform. The New York Times Magazine recently ran a cover article about mapping the connectome, all of the connections that link all of the neurons in someone’s brain. Many of these connections are formed and reinforced as a result of our experiences, and their sum total …

Scientists Have Found That Memories Can Be Passed Down Through Generations In Our Genes

New research from Emory University School of Medicine, in Atlanta, has shown that it is possible for some information to be inherited biologically through chemical changes that occur in DNA. During the tests they learned that that mice can pass on learned information about traumatic or stressful experiences – in this case a fear of the smell of …

What Do Resident Physicians Know about Nutrition? An Evaluation of Attitudes, Self-Perceived Proficiency and Knowledge

Abstract Objective Despite the increased emphasis on obesity and diet-related diseases, nutrition education remains lacking in many internal medicine training programs. We evaluated the attitudes, self-perceived proficiency, and knowledge related to clinical nutrition among a cohort of internal medicine interns. Methods Nutrition attitudes and self-perceived proficiency were measured using previously validated questionnaires. Knowledge was assessed …

How does the brain develop in individuals with autism?

Geneticists at Heidelberg University Hospital’s Department of Molecular Human Genetics have used a new mouse model to demonstrate the way a certain genetic mutation is linked to a type of autism in humans and affects brain development and behavior. In the brain of genetically altered mice, the protein FOXP1 is not synthesized, which is also …

Why Is Physical Activity So Good for Your Brain?

This is really interesting. Apparently physical activity increases white matter integrity. White matter consists of cells and axons that are responsible for communication between the different parts of the brain. The axons in the white matter work best if they are myelinated which means a fatty layer forms around them. This allows nerve cells to …
