Sustained stress can cause Alzheimer’s diseaese in advanced years.
A research on mice has indicated there is an increased risk of dementia in case one remains constantly stressed. Sara Bengtsson, a PhD student from Umea University, in Sweden, tested her theory on mice and found that mice with higher levels of the hormone in their brains suffered impaired learning and memory, Daily Mail reported.

They also had increased brain levels of beta-amyloids — the proteins that form plaque deposits in the brains of Alzheimer’s sufferers.

The American Heart Association’s seven steps for a healthy heart– dubbed Life’s Simple 7 – can also help keep cancer at bay, a new study has claimed.

Laura Rasmussen-Torvik, a professor of preventive medicine at Northwestern University’s Feinberg School of Medicine, said that following even six of the steps can cut cancer risk in half, ABC News reported.

She said that she and her colleagues had a hunch that following healthy-heart guidelines would also decrease the risk of cancer and their findings confirmed it.

According to researchers, a stressful lifestyle can lead to Alzheimer’s disease.

In a mice study, they found that chronic stress sends levels of steroids in the brain soaring. This not only accelerates the development of Alzheimer’s but also boosts levels of the toxic plaque amyloid beta, which can ravage the brain, the Daily Express reported.

Stress steroids could affect the brain’s general activity, said Sara Bengtsson, of Sweden’s Umea University.

Children who avoid scary situations are likely to have anxiety disorders, a new study has found.

The researchers developed two eight-question surveys – the Children`s Avoidance Measure Parent Report and the Children`s Avoidance Measure Self Report.

The questionnaires ask details about children`s avoidance tendencies, for instance, in addressing parents, “When your child is scared or worried about something, does he or she ask to do it later?”

Obese cardiac patients are less likely to die compared to their normal weight counterparts, researchers have claimed.

The British Heart Foundation said that where people stored fat, not just general obesity, was important in this.

One explanation has been that maybe such patients were fitter, despite their size for example they were taking more exercise.

To see if this was the case, University College London researchers looked at data from patients who took part in the Health Survey for England or Scottish Health Survey .

A new plague of antibiotic resistant infections may emerge with even common urinary tract infections now resistant to conventional treatment, Australia`s superbug experts have warned.

They noted that powerful intravenous antibiotics are now being used to beat urinary tract infections that previously could be treated simply with a pill, News.com.au reported.

And unless the government regulates antibiotic use medical advances like organ transplants, joint replacements and critical care medicine will be under threat from rampant infections, the stated.

A new study has found that fretting over stressful events could trigger inflammation in one`s body.

The study found that levels of C-reactive protein, a marker of tissue inflammation, rose when participants were asked to ruminate on a stressful incident.

This is the first study to directly measure the effect of negative thought on the body.

Peggy Zoccola, an assistant professor of psychology at Ohio University, US, the study`s lead author, said: “Much of the past work has looked at this in non-experimental designs.”

London, Mar 17 (ANI): Chocolate-flavoured teas that are low on calories but high on treat­factor have won Newcastle-based twins Jodi and Stella Kean the backing of a Start-Up team.

The 24-year-olds started their own novelty tea business after their plans to open a tea bar collapsed.

“When the lease on the shop fell through we came up with the idea for choclateas. I don’t think people realise how many calories and how much sugar is in a cup of hot chocolate. We wanted to create something that felt like a treat but was healthy,” the Daily Express quoted Stella as saying.

Olive oil leads to satiety, shows a study that points out the mechanism behind it.

Reduced-fat food products are gaining popularity. More and more people are choosing “light” products in an attempt to lose weight, or at least in the hope that they would not gain pounds.

But whether these products are effective or not is a matter of dispute: while it is true that they contain fewer calories, people tend to overcompensate by eating more if they do not feel full.

The contrast between your facial features and surrounding skin may reveal your age, as it is a tell-tale sign that people unconsciously use to decipher how old someone looks, researchers say.

Contrast between the features and the surrounding skin decreases as we age resulting in older faces to have less contrast than younger ones, Psychology Professor Richard Russell who collaborated with researchers from Epidermal and Sensory Research and Investigation Center CERIES, said.

Stressing the need for better healthcare, President Pranab Mukherjee Friday said here that progress in the health sector was the key to India`s future prominence in the world.

Anyone who needs a reason not to overindulge on St. Patrick`s Day or on any other day of the year, the American Chemical Society (ACS) video shows alcohol`s effects on the body.

For those celebrating St. Patrick`s Day with green beer, moderation is key, as alcohol has several negative effects on your body – many of which usually amount to a miserable morning-after.

Produced by the American Chemical Society (ACS) Office of Public Affairs, The Chemistry of Alcohol and Hangovers video explains the science behind these unpleasant after-effects that excessive drinking can have on the body.

Unhealthy eating can cause women who are concerned about their diet and self-image, to experience a worsening of their moods, a new study has revealed.

In the study by Penn State researchers, college-age women who were concerned about their eating behaviors reported that moods worsened after bouts of disordered eating, Kristin Heron, research associate at the Survey Research Center Penn State researchers.

“There was little in the way of mood changes right before the unhealthy eating behaviors. However, negative mood was significantly higher after these behaviors,” Heron said.

Autism may result from chronic danger signaling by mitochondria, cell structures that supply our cells with energy, a new study has suggested.

The study, which presents a novel theory about the cause and potential treatment of autism, is being supported by one of Autism Speaks` first Suzanne and Bob Wright Trailblazer Awards ( Autism Speaks is the world`s leading autism science and advocacy organization).

It is being conducted by Trailblazer researcher and mitochondrial medicine specialist Robert Naviaux, M.D., Ph.D., of the University of California, San Diego.

Women who work the night shift may have an increased risk of ovarian cancer, new research has warned.

The authors base their findings on 1101 women with the most common type (epithelial) of advanced ovarian cancer; 389 with borderline disease; and a comparison group of 1832 women without ovarian cancer.

The women, who were all aged between 35 and 74, were asked about the hours they worked, including whether they had ever worked night shifts.

Treatment as soon as HIV infection has been identified may be enough to “functionally cure” about a 10th of those diagnosed early, researchers in France have suggested.

The researchers said that 14 people who stopped therapy have since shown no signs of the virus resurging, the BBC reported.

The group of patients, known as the Visconti cohort, all started treatment within 10 weeks of being infected. They were given a course of antiretroviral drugs for three years, on average, but then stopped.

A surprisingly high number of women – one in seven – suffers from postpartum depression, according to a new, large-scale study by a Northwestern Medicine researcher.

The study, which included a depression screening of 10,000 women who had recently delivered infants at single obstetrical hospital, revealed a large percentage of women who suffered recurrent episodes of major depression.

Lead study author Katherine L. Wisner, M.D said the study underscored the importance of prenatal as well as postpartum screening.

Adding daily green tea and coffee to your daily diet may help lower your risk of having a stroke, according to researchers.

This is the first large-scale study to examine the combined effects of both green tea and coffee on stroke risks, said Yoshihiro Kokubo, M.D., Ph.D., F.A.H.A., F.A.C.C., F.E.S.C., lead author of the study at Japan`s National Cerebral and Cardiovascular Center.

“You may make a small but positive lifestyle change to help lower the risk of stroke by adding daily green tea to your diet,” Kokubo stated.

For those with irritable bowel syndrome who wonder if stress aggravates their intestinal disorder, a new study has shown that it’s not all in their head.

Researchers at the University of Michigan Health System revealed that while stress does not cause IBS, it does alter brain-gut interactions and induces the intestinal inflammation that often leads to severe or chronic belly pain, loss of appetite and diarrhea.

Early detection and prevention is the best option to manage the rapidly rising chronic kidney disease in India, doctors said Wednesday on the eve of World Kidney Day.

“Kidney disease often goes undetected because symptoms may not appear until the organs are actually failing. Those who have poor diabetic control, high blood pressure, smokers and have a family history of chronic kidney disease should do early detection by simple urine analysis and blood test,” said Dinesh K. Dhanwal, a professor of medicine and an endocrinologist at Maulana Azad Medical College.

Exercising just two or three times a month from childhood can lead to improved brain function in later life, according to a new study.

People perform better in mental tests at the age of 50 if they have engaged in regular intense activity, such as playing sport, running, swimming or working out in the gym, since childhood, UK researchers have found.

Levels of exercise in more than 9,000 people were examined at the ages of 11, 16, 33, 42, 46 and 50.

Nearly 6,000 chickens were culled and a large quantity of eggs destroyed in Bihar`s Purnea district in the last five days following an outbreak of bird flu and officials asked to take all preventive measures to check the spread of the virus, an official said Thursday.

Rajesh Kumar, director of state animal husbandry department, said he has ordered the administration to keep a close watch on the situation for two months.

“Three blocks in the district have been declared high risk zones,” he said, adding that the H5N1 virus was detected in chickens last week.

Delhi Chief Minister Sheila Dikshit Wednesday launched the Delhi State Cancer Institute Centre at Janakpuri Super-Speciality Hospital.

She said the government intended to make the unit in the west Delhi hospital a comprehensive cancer care centre with latest equipment for radio-therapy, radio-diagnosis and labs.

“The government would commission two more such centres in south Delhi`s at Chhatarpur and north Delhi`s Alipur,” she said.
