Futurity | 'Bendable' brain adapts to what eyes see - 0 views

  • The human brain never stops adapting to its environment in a quest to formulate what the mind perceives based on what the eyes see, according to a new study. The research adds credence to the notion that adult brains can be retrained following trauma or surgery or even from the effects of aging or eye misalignment, says Jan Brascamp, a research associate working with Randolph Blake, Centennial Professor of Psychology at Vanderbilt University. Details appear in the July 29 issue of Current Biology.

WebMD | Positive Thinking Helps Heart Patients - 0 views

  • Hospitalized patients diagnosed with coronary artery disease who had a positive outlook about their recovery were less likely to die over the next 15 years and had better physical functioning after one year, according to a new study. Previous studies have found that heart patients’ optimism and expectations have positively influenced their functional status and return to work. But researchers say this study takes it a step further by showing how patient beliefs affect their health over the long term and ultimate survival. The findings are published in the Archives of Internal Medicine.
  • Researchers at Duke University Medical Center followed 2,818 heart patients after they had coronary angiography to evaluate blood flow in the coronary arteries of the heart. They measured how patient expectations affected their recovery and ability to perform normal physical activities. Patients completed a questionnaire about their future lifestyle (e.g. “My heart condition will have little or no effect on my ability to do work,” “I expect that my lifestyle will suffer because of my heart condition”) and their future outcome (e.g. “I can still live a long and healthy life,” “I doubt that I will ever fully recover from my heart problems”).
  • the death rate of patients with the highest expectations was 31.8 deaths per 100 patients, compared to those with the lowest expectations at 46.2 deaths per 100 patients.

  • The patients with optimistic expectations had an associated 17% decrease in their likelihood of dying over the 15-year study period.

MSN | Stay-Calm Solutions From Stress Survivors - 0 views

  • "Research shows it's possible to cushion yourself against stress, and the tactics we're using with soldiers also apply to real folks and more common types of anxiety." Key to the recent breakthroughs is a much clearer picture of how destructive stress can be. Persistent anxiety can kill neurons in brain structures concerned with memory and decisionmaking, and such damage is even visible on brain scans.
  • Fortunately, experts are learning that all along the continuum—from severe anxiety disorders to garden-variety worry—coping and even prevention tactics are highly effective. Here's what new PTSD science can teach all of us about outsmarting stress. If these solutions work for soldiers in Iraq and Afghanistan, they can certainly help the rest of us on the home front.
  • Researchers are learning that exercise doesn't just soothe stress, it also fortifies brain cells so they're less vulnerable to anxiety in the future.

  • While all exercise adds to your resilience, PTSD experts find that outdoor activities are particularly beneficial

That's Fit | New Study Shows Exercise Improves Math Scores in Overweight Kids - 0 views

  • According to a recent study, regular exercise improves the ability of inactive, overweight children to do better in math. Researchers at Georgia Health Sciences University studied 171 sedentary and overweight 7- to 11-year-olds in an effort to identify what happens to children's brains with regular, vigorous exercise.
  • After allowing the kids to engage in fun, playful exercises, such as running games, hula hooping and jump roping, which raised their heart rates to 79 percent of their maximum, scientists used the Cognitive Assessment System and Woodcock-Johnson Tests of Achievement III, tests that measure abilities such as planning and academic skills, to identify brain activity before and after the bouts of physical activity. Students showed an increase in complex thinking and decision making -- the areas of the brain that are used in math. In fact, the more the children exercised, the more their brains responded. Intelligence scores increased an average 3.8 points in those exercising 40 minutes per day for three months. Those who exercised just 20 minutes a day also benefited, just in a smaller dose. Researchers noted that the improved math skills were "remarkable," since no math lessons were given as part of the study. This suggests longer, more sustained periods of vigorous physical activity throughout the entire school year could produce even higher results. And researchers believe all children -- not just those who are overweight -- could benefit with improved reasoning and complex thinking skills.
  • In a country where one-third of our children are overweight, it is increasingly important to motivate schools and parents to encourage daily physical activity. The Center for Disease Control recommends at least 60 minutes of exercise a day for children, yet there is no federal mandate for minimum standards in schools. Each state is responsible for setting their own requirements, and unfortunately, with increasing budget cuts, not all schools comply or engage the children in quality-rich physical education.

American Journal of Medicine | Adherence to Healthy Lifestyle Habits in US Adults, 1988... - 0 views

  • Lifestyle choices are associated with cardiovascular disease and mortality. The purpose of this study was to compare adherence to healthy lifestyle habits in adults between 1988 and 2006.
  • Analysis of adherence to 5 healthy lifestyle trends (≥5 fruits and vegetables/day, regular exercise >12 times/month, maintaining healthy weight [body mass index 18.5-29.9 kg/m2], moderate alcohol consumption [up to 1 drink/day for women, 2/day for men] and not smoking) in the National Health and Nutrition Examination Survey 1988-1994 were compared with results from the National Health and Nutrition Examination Survey 2001-2006 among adults aged 40-74 years.
  • Generally, adherence to a healthy lifestyle pattern has decreased during the last 18 years, with decreases documented in 3 of 5 healthy lifestyle habits. These findings have broad implications for the future risk of cardiovascular disease in adults.
