Stigma often prevents patients from acknowledging an Alzheimer’s diagnosis. A series of high-profile disclosures may help change that.

The 1918 Spanish flu outbreak killed more people than both world wars. Don’t imagine such a thing could never happen again, says the Guardian columnist Martin Kettle

The Centers for Disease Control is sending a bizarre new warning -- urging people to stop using dead bats as Halloween decorations. The national Fish & Wildlife Service says they're seizing illegal dead bats shipped into the U. S. Most of the time the spooky specimens are fully taxidermied. People use them as wall hangings or outdoor decor. The biggest problem? Dead bats can carry disease.

Revolutionary work on the body’s immune system and a host of new drug trials mean that beating cancer may be achievable

Dogs have been trained to sniff out malaria in socks worn by African children, and they are remarkably good at it.

Alzheimer’s is a spectrum disorder that exhibits differently in everyone. Learn how to treat the individual in this informative interview with neurologist Gayatri Devi, M.D.

A recent study suggests that people diagnosed with stress-related disorders may be more prone to autoimmune disease, but did not prove cause and effect.

Scientists know genes are responsible for roughly half your chance of having a heart attack, but they didn't know which genes were important. Now, in a huge world-first study, Australian scientists say they have discovered the DNA patterns that can raise our risk. People with high-risk DNA are more than four times more likely to have a heart attack than people with low-risk DNA, their study reveals.

A study in mice hints at a new approach for thwarting neurodegenerative diseases—but many questions remain.

'There haven’t been any new drugs last 15 years, so it’s very promising to have uncovered a reason why some of that research may have failed'

Influenza viruses circulate better in cold, dry air. But scientists who've studied six years of illness data from across the country have found out that the weather isn't as big a factor in transmission rates in big cities. The flu is more persistent all winter in a big metro area.

Hints at potential treatments for age-related dementia and memory loss

The Spanish flu emerged as the world was recovering from years of global war. It was to have some surprising and far-reaching effects.

By releasing specially bred mosquitoes that can't transmit viruses, scientists have been able to virtually eradicate dengue fever from the city of Townsville, Queensland, in north-eastern Australia – and they say the same methods could be scaled up

How did British medical worker Janet Parker become the world's last victim of smallpox? By Monica Rimmer.

A study shows higher risk of fatal lung disease in adults exposed to cigarette smoke in childhood.

Nearly 700 million people suffer from mosquito-borne diseases—such as malaria, West Nile, Zika and dengue fever—each year, resulting in more than 1 million deaths. Increasingly, many species of mosquitoes have become resistant to the popular pyrethroid-based insecticides. Today, researchers report a new class of mosquito repellents based on naturally occurring compounds that are effective in repelling mosquitoes with potentially fewer environmental side effects than existing repellents.

The World Health Organization says the number of measles cases in Europe jumped sharply during the first six months of 2018 and at least 37 people have died. The U.N. agency’s European office said Monday more than 41,000 measles cases were reported in the region during the first half of the year — more than in all 12-month periods so far this decade.

It may be possible in the future to screen patients for Alzheimer’s disease using an eye exam. Using technology similar to what is found in many eye doctors’ offices, researchers at Washington University School of Medicine in St. Louis have detected evidence suggesting Alzheimer’s in older patients who had no symptoms of the disease. Their study, involving 30 patients, is published Aug. 23 in the journal JAMA Ophthalmology.

The Netherlands is pioneering new ways to treat dementia, with sensory aids, soothing music and other tools to calm and nurture patients.

Taking a low-dose aspirin every day has long been known to cut the chances of another heart attack, stroke or other heart problem in people who already have had one, but the risks don't outweigh the benefits for most other folks, major new research finds.

Migration and a global shipping network have flattened biodiversity worldwide.

Money has poured into Alzheimer's research, but until very recently not much of it went toward investigating infection in causing dementia. A million dollar prize may lead more scientists to try.

New research from USC has uncovered a previously unknown genetic risk factor for Alzheimer’s disease and related dementias. The study provides insights on how these conditions, and other diseases of aging, might one day be treated and prevented. The research from the Cohen Lab at the USC Leonard Davis School of Gerontology sheds new light on the protective role of a naturally occurring mitochondrial peptide, known as humanin.

Many specimens were discovered to be carrying bacteria and worms that can be passed on to humans, prompting experts to talk about a public health problem

For the first time, a case of rat hepatitis E has been discovered in a human in Hong Kong. A 56-year-old man has been diagnosed with the disease, researchers from the University of Hong Kong said. It was not previously known the disease could be passed from rats to humans. "Previous laboratory experiments have found that rat hepatitis E virus cannot be transmitted to monkeys, and human hepatitis A virus cannot be transmitted to rats," said Dr. Siddharth Sridhar...

Tuberculosis (TB) isn’t a disease Americans hear about much about these days, but that’s not true for the rest of the world. TB is currently the deadliest infectious disease, responsible for 1.6 million deaths last year, most of them in the developing world.

China has announced a 14% jump in the number of its citizens who are living with HIV and Aids. More than 820,000 people are affected in the country, health officials say. About 40,000 new cases were reported in the second quarter of 2018 alone. The vast majority of new cases were transmitted through sex, marking a change from the past. Traditionally, HIV spread rapidly through some parts of China as a result of infected blood transfusions.

A new study from Johns Hopkins shows that individuals with early onset Alzheimer's disease—those under the age of 65—don't benefit from deep brain stimulation, a treatment already proven to be effective for easing motor symptoms of people with Parkinson's disease. "Our results suggest that as we look at deep brain stimulation as a treatment for Alzheimer's disease, we should probably focus on those over 65, which is the bulk of people with Alzheimer's," says Jeannie-Marie Leoutsakos, associate professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine.

British woman who can smell Parkinson’s disease has helped scientists discover 10 molecules linked to the condition which could lead to the first diagnostic test. Researchers at Manchester University first began to believe Parkinson’s might have a discernible odour when Joy Milne of Perth, Scotland, claimed she detected a change in the odour of her husband Les six years before he was diagnosed with the condition.

A strong virus, a less-than-effective vaccine, and an IV bag shortage that goes back to Hurricane Maria.

An ingredient commonly found in toothpaste could be employed as an anti-malarial drug against strains of malaria parasite that have grown resistant to one of the currently used drugs.

Overhead far-UVC light, a type of ultraviolet light that is harmless to humans, effectively killed airborne flu virus, found researchers at Columbia University.

The gut microbiota, the collection of all bacterial members in the intestinal tract, plays a key role in health. Disruption of the indigenous microbiota by a variety of stressors, including antibiotic therapy and intestinal infections, is associated with multiple health problems.

Melioidosis quietly causes thousands of deaths each year. Meet the doctor who made it his mission to make the world take notice.
