Scientists have performed the first successful neural stem cell transplant into the brains of four boys with Pelizaeus-Merzbacher disease. The disorder is a rare but tragic condition that impacts motor abilities, coordination and cognitive function. Pelizaeus-Merzbacher disease does its damage by stripping away the fatty substance called myelin that surrounds brain cells. Myelin acts as an insulator, like rubber on the outside of a wire, helping the electrical impulses that carry information in the brain travel at high speeds.

With no cure in hand for Alzheimer's disease, many ask why someone would necessarily want an early diagnosis. But research continues to focus on detecting the earliest signs of dementia, and on the factors that give rise to some dementias or fuel their relentless progression. Those findings may point the way to prevention strategies. And they may allow physicians to recognize Alzheimer's disease and other dementias before they have taken a measurable toll. Stopping or slowing it there might be easier than reversing it, and could, for all practical purposes, be as good as a cure.

There's little argument that exercise is good for your body, but researchers have found that exercising to music may make you smarter too. An Ohio State University study found that verbal skills improved significantly in cardiac rehabilitation patients who exercised on a treadmill while listening to Vivaldi's "Four Seasons." "There have been a number of studies that have looked at the effects of just exercise or music on cognitive function," said Charles F.

Adolescent soccer players need better education about the symptoms of concussion and dangers of playing with head injuries, medical experts said Tuesday. In a new report, the Institute of Medicine, part of the National Academy of Sciences, said that studies of the effects of "heading"--hitting the ball with the head--have been inconclusive and that additional research is needed. But the risk of concussion in contact sports, including soccer is real, according to the report.

Walking promotes good physical health, but it may also help maintain memory and cognitive function for years, a study finds. The research, published online Wednesday in the journal Neurology , is based on a study of 299 men and women, average age 78, who were followed for nine years. The study participants were asked about their physical activity, which was calculated as number of blocks walked per week (walking was the most common exercise). Study subjects walked from zero to 300 blocks over a one-week period.

I have suffered from insomnia for many years. My doctor prescribed Ambien , but it doesn't seem to be working very well anymore. I also suspect that it affected my memory. Now the doctor is suggesting the antidepressant amitriptyline (Elavil) . The side effects I have read about make me nervous. Is there any herb or home remedy that might help me get some sleep? Amitriptyline is an old-fashioned (tricyclic) antidepressant. Some people experience a morning hangover effect that leaves them drowsy and disoriented.

Looking for ways to save money in 2014? Here's some advice from doctors: Stop buying vitamins. Time after time, studies have shown that vitamin and mineral supplements don't prevent disease or death. And yet consumers keep buying them, lament the authors of an editorial published in Tuesday's edition of the Annals of Internal Medicine. A 2011 report from the National Center for Health Statistics estimated that 53% of American adults used some type of supplement in the years 2003 to 2006, with multivitamin/multimineral formulations being the most popular.

There's a phrase that has haunted America for decades, one fraught with failure: "Breaking the cycle of poverty. " Despite the ongoing efforts of government and a host of private foundations, income inequality continues to grow and the poor are ever more likely to remain poor. Many factors favor the rich getting richer while the poor stagnate. The wealthy benefit from economies of scale, as the best prices and lowest interest rates are more readily available to those who least need them.

It can take several days to recover after experiencing a few nights of little sleep, according to a new study. Researchers found that even a catch-up night of 10 hours of sleep may not be enough to restore many people after they have a few nights of bad sleep. The study involved 159 adults who were assigned to sleep a certain number of hours a night. The participants underwent computerized neurobehavioral tests during the day to assess their cognitive function. Their results were compared to see how well they recovered after various amounts of sleep deprivation.
