Restless legs syndrome (RLS) is a sensory-motor disorder that
causes an irresistible urge to move the legs, often accompanied
by an uncomfortable "creepy-crawly" sensation. RLS affects 3% to
5% of adults and is twice as common in women as in men. Symptoms
typically flare at night, just as you're settling down in bed,
but they may also arise when you're resting in a chair. RLS not
only causes discomfort and distress, but can also wreak havoc on
sleep, causing daytime sleepiness and mood changes. Fortunately,
certain lifestyle strategies can help you manage milder forms of
RLS, and several medications can provide relief for more serious
Resolutions are notoriously hard to keep, especially when they're aimed at health behaviors such as losing weight, eating better, and exercising more. In fact, no matter when we decide to make a change — or how strongly we're motivated — adopting a new, healthy habit, or breaking an old, bad one, can be terribly difficult. But research suggests that any effort you make is worthwhile, even if you encounter setbacks or find yourself backsliding from time to time.
Scientists have long known that certain nutrients are essential for brain development and function. There's also evidence that good nutrition can help stave off cognitive decline in older people. But studies of single nutrients have largely been disappointing, and research on the relationship between overall diet and brain function generally relies on food frequency questionnaires, which can be misleading because of faulty memories and the inability to take account of nutrient absorption.
Now researchers have conducted the first study using nutrient biomarkers and brain imaging to analyze the effect of diet on cognitive function and brain volume. Their main finding is that higher blood levels of omega-3 fatty acids and vitamins B, C, D, and E are associated with better memory and thinking in older people.
Women who undergo breast-conserving surgery (lumpectomy) for early-stage breast cancer usually receive radiation therapy as a part of their treatment. Numerous studies have found that mastectomy (which removes the entire breast) is no more effective than lumpectomy plus radiation in improving survival rates.
