The King’s Speech has won almost universal praise for its portrayal of reluctant monarch George VI’s stuttering. Harvard Health Letter editor Peter Wehrwein takes you behind the scenes with Alex Johnson, an expert in speech and stuttering at the MGH Institute of Health Professions in Boston; Caroline Bowen, an Australian speech-language therapist; and a few other scattered sources.

Cereal fiber–from whole wheat bread, whole wheat pasta, brown rice, barley and other whole grains–seems to offer more protection against heart disease and other chronic conditions than fiber from fruits and vegetables. The benefit isn’t necessarily from the fiber alone, but the natural package of nutrients that comes with the fiber. Processed foods, which are often stripped of their fiber and nutrients and then “fortified” in the manufacturing process, don’t measure up.

An elegant new study showing that a cell phone can stimulate brain activity is certain to heat up the debate about whether or not cell phone use is linked to cancer. It’s an important signal that it’s high time scientists take a harder look at how the energy radiated by a cell phone, a mobile phone, or any other energy-emitting device we hold next to our heads affects the brain.

The latest hubbub about taking zinc to shorten a cold is media hype at its finest. The review that sparked the media storm on zinc and colds says there’s a lot more to be done before recommending taking zinc for the common cold. The negative side effects of zinc are also worth considering.

Deep brain stimulation, an experimental treatment for obsessive compulsive disorder (OCD), is being misused, say prominent neuroscientists and ethicists in a hard-hitting paper in the journal Health Affairs. Their concerns echo cautions reported last year in the Harvard Mental Health Letter.

Tomorrow night at 6:30 p.m., tens of millions of television sets will be turned on as Americans sit down and participate in that unofficial national holiday called “watching the Super Bowl.” For many, it’s an excuse to see funny ads and the half-time show and to eat (how many of those spanking new Dietary Guidelines will be broken?), drink, and socialize. But […]

This picture shows the view from my office window in Boston: dull, dreary, and depressing — at least on overcast days like today. Lack of light is one of the reasons that people feel mentally foggy. One of the bloggers I follow, Rachel Zimmerman of WBUR’s CommonHealth blog, recently wrote that she’s been drinking three […]

When reports arrived that accused gunman Jared Lee Loughner had opened fire in Tucson, Arizona on January 7, journalistic first responders linked the incident to the fierceness of political rhetoric in the United States. Upon reflection, some of the discussion has turned to questions about mental illness, guns, and violence. And plenty of reflection is […]

Here’s an important equation that all of us—doctors included—should know about health care, but don’t: More ≠ Better “More does not equal Better” applies to diagnostic procedures, screening tests meant to identify problems before they appear, medications, dietary supplements, and just about every aspect of medicine. That scenario is spelled out in alarming detail in […]

For years now, both individual researchers and respected scientific organizations such as the Institute of Medicine have tried to refute a persistent myth — that childhood vaccines cause autism. The myth began after a small study published in 1998 in the Lancet by Andrew Wakefield and colleagues at Royal Free Hospital and School of Medicine […]

Does echinacea, the popular natural cold remedy, really work? It depends on what you mean by “work.” Results reported in today’s Annals of Internal Medicine found that echinacea may reduce the length of a weeklong cold by 7 to 10 hours and make symptoms a little less onerous. That can’t be characterized as a major effect, so many people may figure that […]

Perhaps as many as one in every 5 American adults will get a prescription for a painkiller this year, and many more will buy over-the-counter medicines without a prescription. These drugs can do wonders—getting rid of pain can seem like a miracle—but sometimes there’s a high price to be paid. Remember the heavily marketed COX-2 inhibitors? Rofecoxib, sold as Vioxx, […]

Stroke killed 2,000 fewer Americans in 2008 (the last year with complete numbers) than it did in 2007, the Centers for Disease Control and Prevention (CDC) said yesterday in its latest annual Deaths report. That dropped stroke from the third leading cause of death in the United States to the fourth. Good news? Yes and […]

Vitamin D has been talked about as the vitamin — the one that might help fend off everything from cancer to heart disease to autoimmune disorders, if only we were to get enough of it. “Whoa!” is the message from a committee of experts assembled by the Institute of Medicine (IOM) to update recommendations for vitamin D (and for calcium).

One of the things I like most about Thanksgiving is the laughter around the dinner table. The food is great, make no mistake. But it’s the sounds of happiness—the high peal, the good-natured guffaw, the snort-and-shaking-shoulders, and the deep belly laugh—that really make me give thanks. Laughter isn’t just a way to stay connected with […]

As usual, Harvard Health Publishing’ writers and editors have been busy covering a range of health topics. Here is a small sampling. To read more, visit us at www.health.harvard.edu. Health apps.

Lung cancer is usually discovered late when it’s difficult to treat and has often spread outside the lung. A reliable screening test to find it at an earlier, more treatable stage would be a legitimate breakthrough—and could potentially save thousands of lives. About 160,000 Americans die each year from lung cancer, which is more than who die from breast, prostate, and […]
