Playing outdoors can be beneficial to your child’s eyesight

More time outdoors had a protective effect and reduced the chances that a child would go on to need myopic refractive correction in the future. The size of the effect was impressive

Playing outdoors can be beneficial to your child’s eyesightThe ready availability of technology may make the children of today faster at configuring a new smartphone, but does all of that screen time affect the development of their eyes? While conventional wisdom dictates that children should do less up-close viewing, sit farther from the television and perhaps even wear their eyeglasses less, we have […]

Biomarkers for cognitive impairment in Parkinson’s found by researchers

The biomarkers that were found to predict this cognitive decline were: a deficiency in dopamine, a "diffuse" decrease in the brain volume across the frontal, temporal, parietal, and occipital lobes, pathological levels of beta-amyloid plaques - just like those found in Alzheimer's disease - and some genetic variations

Biomarkers for cognitive impairment in Parkinson’s found by researchersParkinson’s disease (PD) is “the second most common neurodegenerative disease after Alzheimer’s disease,” according to the Centers for Disease Control and Prevention (CDC). While there is no cure for PD, there are therapies that aim to slow down the advancement of the disease. Usually, however, PD is diagnosed when the symptoms become apparent, by which […]

What happens to your brain when you give up sugar?

Most of us prefer sweets over sour and bitter foods because, evolutionarily, our mesolimbic pathway reinforces that sweet things provide a healthy source of carbohydrates for our bodies

What happens to your brain when you give up sugar?Anyone who knows me also knows that I have a huge sweet tooth. I always have. My friend and fellow graduate student Andrew is equally afflicted, and living in Hershey, Pennsylvania — the “Chocolate Capital of the World” — doesn’t help either of us. But Andrew is braver than I am. Last year, he gave […]

Dopamine is one of the reasons why you don’t feel motivated to exercise

While many people are aware of the benefits of physical activity in theory, many of us find it particularly hard in practice to stay physically active. New research may help to explain why this is so

Dopamine is one of the reasons why you don’t feel motivated to exercisePerhaps you have told yourself many times that, as of next week, you will start exercising more. Perhaps next month, maybe even next year. For many of us, however, sticking to a disciplined program of physical exercise is one of the hardest New Year’s resolutions. New research offers clues as to why finding the motivation […]

New information reveals how dopamine works in Parkinson’s patients

Researchers use high-end technology to examine dopamine levels in Parkinson’s patients who were undergoing brain surgery at thousand times faster rate than previously recorded in humans

New information reveals how dopamine works in Parkinson’s patientsResearchers from Virginia Tech’s Carilion Institute have known about dopamine’s link to learning for some time, but they wanted to dig a little deeper in a new study. Using high-end technology, the researchers examined dopamine levels in Parkinson’s patients who were undergoing brain surgery at a rate a thousand times faster than previously recorded in […]
