If you take prescription opioids, you may have experienced withdrawal symptoms at some point—perhaps when you forgot to take a scheduled dose of medication. Opioid withdrawal is highly unpleasant. If you experience withdrawal symptoms, this does not meant that you cannot get off opioids...
Over the last century, myopia (short-sightedness) has risen to epidemic proportions. In South-East Asia nearly 90% of school leavers are now affected. In the West the figures are not as dramatic, but it appears to be similarly increasing.
The most exciting recent development in human genetics research has been the ability to perform large-scale systematic studies of genetic variation in thousands of people.
My mother-in-law called me yesterday. She doesn’t quite know what I do for a job but has a vague idea I work with a group seeking to understand and ultimately prevent Alzheimer’s disease.
What you say when a doctor asks how you feel is as good—or perhaps even better—than any test to predict long-term illness or death.
Being overweight and not getting enough exercise are considered major contributors to insulin resistance and, ultimately, type 2 diabetes. But new research suggests specific imbalances in gut bacteria play a role, too
Organ transplantation saves lives. People with end-stage kidney disease who receive a transplant tend to live much longer than those who undergo dialysis. A kidney from a living donor will last from 12 to 20 years, on average, compared to eight to 12 years for a kidney from a deceased donor.
Head trauma is a major public health concern in the United States, with indirect and direct health-care costs approaching nearly US$1 billion annually. Worse, head trauma also can cause short- and long-term health problems and, in children, problems with academics, headaches and behavioral health issues.
You have forgotten where you put your car keys, or you can’t seem to remember the name of your colleague you saw in the grocery store the other day. You fear the worst, that maybe these are signs of Alzheimer’s disease.
Something as simple as picking up a cup of tea requires an awful lot of action from your body. Your arm muscles fire to move your arm towards the cup. Your finger muscles fire to open your hand then bend your fingers around the handle.
Chronic fatigue syndrome, a condition where normal exertion leads to debilitating fatigue that isn’t alleviated by rest, has long mystified scientists. There are no known triggers, and diagnosis requires lengthy tests.
The estimated annual health care costs related to obesity are over $210 billion, or nearly 21 percent of annual medical spending in the United States.
On any ranked list of nasty diseases transmitted by mosquitoes, ticks and fleas in the Western world, Borrelia burgdorferi, would have to lie near the top. These bacteria cause Lyme disease, which was first recognised in the US in the early 1970s among patients in Lyme, Connecticut.

For thousands of years humans have defended themselves from harm by others. But many have proceeded to regularly harm themselves. They have actively searched for substances to ingest, inhale, inject and apply which may give them some immediate relief but damage or destroy their lives over time.
The World Health Organisation’s cancer arm made two announcements this week: one welcome and one not so welcome.
The “common cold” is common. Most of us will have at least one or two per year. Children get sick more often and very young children often get more than five colds per year.
Scientists have uncovered a link between emotional stress and diabetes, with roots in the brain’s ability to control anxiety.
A recent study by the National Institutes of Health found that more than one in three people in the United States have experienced pain of some sort in the previous three months. Of these, approximately 50 million suffer from chronic or severe pain.
Everyone knows that Britain’s conclusive victory over Napoleon was at Waterloo. The story of that day – the squares of infantry repulsing cavalry charges, the Imperial Guard retreating under murderous musket fire delivered by a red line of soliders, the just-in-time arrival of Field Marshal Blücher’s Prussian army – is one of excitement, horror and heroism.
The near panic caused by the rapid spread of the Zika virus has brought new urgency to the question of how best to control mosquitoes that transmit human diseases. Aedes aegypti mosquitoes bite people across the globe, spreading three viral diseases: dengue, chikungunya and Zika.
Marisa Fisher's research suggests people with Williams syndrome can learn to say no to strangers, refuting past studies that indicated sociability may be hard-wired in individuals with Williams syndrome.
Alcohol: why do we drink it? People have been consuming alcohol for at least 10,000 years. And when drinking water was rather risky, alcohol seemed a much safer bet. Amaldus of Villanova, a 14th-century monk, even wrote that alcohol “prolongs life, clears away ill humors, revives the heart and maintains youth”.
"As doctors, we throw things like antihistamines, ointments, and lotions at patients who suffer chronic itching, but if there is something profoundly abnormal about the immune system—as it appears there is—then we can't solve the itching until we address those underlying causes," says Brian S. Kim.
