Strokes are increasingly hitting younger people and the incidence of the crippling condition worldwide could double by 2030, warns the first global analysis of the problem.
Though the chances of a stroke jump dramatically with age, the growing number of younger people with worrying risk factors such as bulging waistlines, diabetes and high blood pressure means they are becoming increasingly susceptible.
Worldwide, stroke is the second-leading cause of death after heart disease and is also a big contributor to disability.
Most strokes occur when a clot blocks the blood supply to the brain. Patients often experience symptoms including a droopy face, the inability to lift their arms and garbled speech. If not treated quickly, patients can be left with long-term side effects, including speech and memory problems, paralysis and the loss of some vision.
Scientists combed through more than 100 studies from 1990 to 2010 studying stroke patients across the world and also used modeling techniques when there wasn’t enough data. They found the incidence of stroke has jumped by a quarter in people aged 20 to 64 and that those patients make up almost one-third of the total number of strokes.
Researchers said most strokes still occur in the elderly and that the numbers of people suffering strokes are still increasing as the world’s population ages.
“Some of the increase we will see in strokes is unavoidable because it has to do with people aging, but that doesn’t mean we should give up,” said Majid Ezzati of Imperial College London, one of the study’s authors. Ezzati said countries should focus on reducing smoking rates further, aggressively controlling blood pressure and improving eating habits.
Ezzati said developing countries such as Iran and South Africa that have set up national systems to monitor maternal and child health are a good model for similar initiatives that could help keep stroke risk factors, such as high blood pressure, in check.
Ezzati and colleagues found the death rate from strokes dropped 37 percent in developed countries and 20 percent in developing countries, largely because of better diagnosis and treatment.
Stroke prevalence was highest in East Asia, North America, Europe and Australia. It was lowest in Africa and the Middle East -though researchers said people in those regions may be dying of other ailments before they get old enough to have a stroke.
In the U.S., doctors have already noted an alarming increase in strokes among young and middle-aged Americans, while the number has been dropping in older people.
The research was paid for by the Bill & Melinda Gates Foundation and published online Thursday in the journal Lancet.
“Young people think stroke is only a problem of the elderly, but we need to educate them,” said Dr. Yannick Bejot of the University Hospital of Dijon in France, who co-wrote an accompanying commentary. He added that using illegal drugs such as marijuana and cocaine also boosts the chance of a stroke.
“If young people understood how debilitating a stroke is, maybe they would change their behavior,” he said.
The NIH is donating millions of dollars to fund research that will investigate whether or not vitamin D supplements can effectively prevent type 2 diabetes, Medical Daily reported. The Vitamin D and Type 2 Diabetes study – also known as D2d – will involve more than 20 health centers across the United States. Each health center has pledged to take up the task of analyzing vitamin D’s potential benefits.
The researchers cited the recent increase in the use of vitamin D supplements as a motivating factor for their study.
“Vitamin D use has risen sharply in the U.S. in the last 15 years, since it has been suggested as a remedy for a variety of conditions, including prevention of type 2 diabetes,” said Dr. Myrlene Staten, the project officer for D2d at the National Institute of Diabetes and Digestive and Kidney Diseases. “But we need rigorous testing to determine if vitamin D will help prevent diabetes. That’s what D2d will do.”
The study will follow more than 2,500 volunteers, over the age of 30, who have been diagnosed with prediabetes, a condition characterized by glucose levels that are higher than normal. According to Medical Daily, half of the participants will receive 4,000 international units (IUs) of vitamin D and the other half will receive a placebo.
According to the Centers for Disease Control and Prevention, 25.8 million Americans (8.3 percent of the population) suffer from diabetes, and 18.8 million Americans remain undiagnosed. Characterized by the body’s inability to properly metabolize sugar, type 2 diabetes can lead to a range of health problems, including cardiovascular disease, stroke, nerve damage, kidney failure and many more.

For years, people with a family history of Alzheimer’s disease have shied away from genetic testing, which could reveal that they carry the ApoE4 protein – a genetic risk factor associated with a 10-fold higher chance of developing the incurable neurodegenerative condition.
However, new research has highlighted a potential pathway for early intervention methods that could help those at a high risk for Alzheimer’s, making genetic screening for the disease as important as cholesterol tests are to preventing heart disease.
Researchers from The Buck Institute for Research on Aging, an independent research association based in Novato, Calif., have long been interested in discovering why ApoE4 is associated with such a high risk for Alzheimer’s disease.
“Why is this the dominant risk factor?” study author Dr. Dale Bredesen, founding CEO of the Buck Institute, told FoxNews.com. “Though people have known this for 20 years, it’s never been clear what it is that ApoE4 does to confer such risk.”
Prior research had focused on the discovery that ApoE4 appears to affect the clearance of amyloid-beta (A-beta), a plaque that builds up in the brains of patients with Alzheimer’s disease. However, Bredesen and his colleagues weren’t convinced that this finding told the whole story of why ApoE4 causes Alzheimer’s.
“Treating that hasn’t worked very well,” Bredesen said. “There’s an emerging feeling, which we believe, that this is more than just about A-beta.”
In a study published in The Proceedings of the National Academy of Sciences, Bredesen and his colleagues analyzed ApoE4 cell cultures and discovered that ApoE4 was also associated with a dramatic reduction in SirT1 – a protein associated with anti-inflammation, anti-aging and longevity.
Bredesen said that as SirT1 decreases, it affects a certain protein crucial to the storage or loss of memories – the amyloid precursor protein (APP).
“You have a molecule called the APP, present in neurons and most cells in your body, and at all times this APP is getting cleaved,” Bredesen said. “It turns out there are two alternative patterns. So it is a little bit like how the government can go on shutdown or active. APP can go in the direction of memory or forgetting.”
In Alzheimer’s, Bredesen says people are on the ‘wrong side’ of this process – causing them to forget rather than retain memories.
However, by maintaining SirT1 levels, researchers believe they may be able to prevent these proteins from going awry. As a result of their discovery, Bredesen and his colleagues attempted to identify drugs that might be able to maintain levels of SirT1 in ApoE4 cell cultures. So far, they have successfully identified four drugs that seem to be effective – though they have yet to test their findings in humans.
“It gives us a leg up on saying, ‘Okay, we can begin to look at how to treat people with ApoE4 even when they’re young to make sure they never get Alzheimer’s, by affecting that link between ApoE4and Alzheimer’s,’” Bredesen said.
Furthermore, Bredesen and his colleagues also performed experiments in which they successfully reinserted SirT1 proteins back into cells already affected by ApoE4. By doing this, they were able to correct the abnormalities present in the cell and return it to a healthy state. This led Bredesen and his colleagues to speculate that treatment might be possible even for those already entering the early stages of Alzheimer’s.
“Most people today don’t want to know if they have ApoE4 because what can they do about it? This could change the landscape where we say everyone should know, just like with high cholesterol or high blood pressure, because you can do something about it,” Bredesen said.

We all know that our health depends on what we eat. Our diet consists of different varieties of food items which are prepared and processed using different methods. During the preparation, storage and processing various changes occur to the naturally obtaining foods and some of these changes are damaging to our body cells. There are many food items which are considered as carcinogenic or which act as cancer causing agents and hence are to be avoided completely, if you want to enjoy a healthy life for a long time. Cancer is one of the most dreaded diseases of the modern age and diet plays an important role in causing cancer, apart from other factors such as genetics, exposure to chemicals and life style. To avoid cancer risk one should have basic knowledge about the food items that are harmful to our body. Most of the mouth watering foodstuffs available in the market are actually carcinogenic and hence a careful selection of food is necessary to protect ourselves and our family members from the risk of developing cancer. The top ten foods which are cancer causing are discussed here.
1. Processed Meat
There are different methods used for processing and preserving meat.
Smoking, salting, curing, pickling and chemical preservatives are the common methods used to preserve meat.
Processed meat items like bacon, hot dogs, sausages, packaged ham, pepperoni etc contain preservatives which make them appear as fresh.
Sodium nitrite and nitrate are the preservatives which are commonly used and these preservatives are found to be carcinogenic. These preservatives increase the chances of colon cancer and pancreatic cancer.
According to World Cancer Research Fund, the consumers should avoid eating processed meats to protect themselves from cancer.
2. Smoked And Burned Food Items
One of the major food items liked by people is the barbequed foods.
Smoking and barbecuing produces polycyclic aromatic hydrocarbons. These chemicals increase the risk of cancer.
Studies have shown that eating burned or charred food items increases the chance of pancreatic cancer by about 60%.
Cooking the food items at high temperature causes the production of chemicals such as hetero cyclic amines which increases the chances of bowel or gullet cancer.
3. GMO Foods
The development of biotechnology has led to the increased production of genetically modified organisms for food purpose.
There are genetically modified vegetables, fish and poultry which are produced using chemicals which promote rapid growth of tumors in humans.
The genetically modified corn, tomatoes, potatoes, soybeans, canola, salmons poses threat to our health and hence should not be considered as cancer –free diet.
It is necessary to execute caution while purchasing food items. Select food items which are certified as non-GMO foods or organic foods which are produced using natural methods.
4. Sweetened Beverages
Sweetened and carbonated beverages like soda and other drinks sold commercially have high levels of refined sugar, added color and preservatives.
Scientific studies have proved that people who consume more than two servings of soda per week have 87% more chance of developing cancer of the digestive system.
The excess sugar present in these beverages provides the best medium for the cancer cells to grow as they provide all the nourishment for the tumor cells.
Chemicals present in soda such as caramel color and its derivative 4-methylimidazole (4-MI) have been considered as cancer causing.
5. Foods With Artificial Sweeteners
In the modern day, people are more aware about the need for maintaining healthy weight and in order to achieve this they depend on various diet foods and beverages which claim to be sugar free.
These foods and beverages which contain artificial sweeteners are more dangerous than the refined sugar.
Artificial sweeteners such as aspartame, Saccharain and Sucralose causes different health related problems including cancer.
6. Contaminated Produce
Most of the conventionally produced fruits and vegetables are contaminated by the use of pesticides.
The most contaminated food produce includes apples, grapes strawberries, oranges and potatoes. More than 90 % of the samples tested found to have pesticide residue.
Pesticides, as such, are toxic to humans and the chemicals in the pesticides increase the risk of cancer and lowered IQ in children.
You should buy fruits and vegetables which are organic or with pesticide-free label.
7. Fried Food Items
Fried items like chips and crisps contain chemical called Acrylamide which may cause cancer in humans.
French fries are cooked using oils containing trans-fats which are unhealthy for the heart.
Frying food items in re -heated oil releases toxic aldehydes which causes cancer and other neurodegenerative diseases.
Most of the fast food outlets use re-heated oil to fry potatoes and other items.
8. Microwave Popcorn
This is another food to be avoided to prevent cancer.
The lining of the microwave popcorn bag contain perfluoroctanoic acid (PFOA) which belongs to a class of compounds that is linked to liver, testicular, and pancreatic cancers.
When the bag is microwaved, the chemicals vaporize and get absorbed by the popcorn, which will ultimately reach your body.
9. Canned Food Items
Most of the canned food items contain preservatives which may react with the can material.
The lining of the cans contains bisphenol-A which is proven to disrupt the normal hormonal activity of the body. This chemical is suspected to cause various problems including cancer.
10. Hydrogenated Oil
Hydrogenated oils are used for preparing the food which needs a longer shelf life.
Hydrogenated vegetable oils can change the structure of the cell membrane and make them more susceptible to diseases like cancer.
These trans-fats are still used by commercial food manufacturing units. Check the food labels to make sure that they are free of hydrogenated vegetable oil.
Do you want to prevent the risk of cancer? Are you looking for the foods to be avoided to lead a cancer free life? Try avoiding the above mentioned food items and select only organic and pest free food items. Avoid artificially colored and sweetened food items. This will help to avoid the fear of developing cancer and lead a relaxed and quality life for many years.
High blood pressure (HBP) is an easily preventable condition, but according to studies it plays a contributing role in more than 15% of deaths in the United States. It doesn’t have any visible symptoms, but can boost the risk of heart attack, stroke, cognitive decline and kidney failure. Thankfully, many most people can reduce their blood pressure the natural way. Your first step should be to get to a healthy weight, then try these strategies for added health benefits.
Just breathe. Slow breathing and meditation decrease stress hormones, which elevate renin, a kidney enzyme that raises blood pressure. Try 5 minutes in the morning and at night. Inhale deeply and expand your belly. Exhale and release all of your tension.
Remember the three Ps: pack in the potassium-rich produce. Loading up on potassium-rich fruits and vegetables is an important part lowering blood pressure. High potassium foods include sweet potatoes, tomatoes, potatoes, bananas, kidney beans, peas, cantaloupe, honeydew melon, prunes and raisins.
Cut the salt. Certain groups of people are more likely than others to have blood pressure that’s particularly sodium sensitive. There’s really no way to tell who is sodium sensitive and who isn’t, but if your HPB is a problem, it’s probably worth cutting out some salt. Experts recommend a diet with a max intake of 1,500 mg of sodium daily. Check the labels on your processed food and season foods with spices, herbs, lemon and salt-free seasoning blends.
Indulge yourself with dark chocolate. Dark chocolate varieties feature flavanols that make blood vessels more elastic. Have up to ½ ounce of dark chocolate with 70% cocoa daily.
Hug a cat. Entertain the idea of owning a pet or spending time with animals. Animals have a natural calming ability and studies have shown people who interact with pets have decreased blood pressure.
If you’re in pain, you may be able to harness your thoughts to help fight it. Skeptical? Studies suggest these pain relief tools can work.
Some techniques work for short term (or acute) pain, others for chronic pain. Either way, here are 12 methods to try.
Thinking about food—whether it’s warm, gooey chocolate brownies or a juicy roast beef meal—has been shown to help alleviate pain from menstrual cramps, migraines, and more.
A study conducted by University researchers found that fantasizing about a favorite food took away some of the pain associated with plunging a hand in icy water (a pretty painful process used in research).
Chocolate was the favorite food fantasy, preferred by 32% of participants in the study, followed by a roast dinner (31%), pasta (14%), pizza (14%) and fruit (4%).
Meditation may be one of the most powerful tonics for pain.
One 2011 study found that mindfulness meditation, which focuses on the breath, reduced pain intensity anywhere from 11% to 70% and pain unpleasantness from 20% to 93% in people who had a heat probe applied to their calves. And these study participants received only 80 minutes of training—other studies indicate that the more meditation hours the better when it comes to subverting pain.
You don’t have to be an expert meditator to reap the benefits of breathing. Practicing deep, diaphragmatic breathing (that’s breathing from the belly rather than shallow inhaling and exhaling from the chest) can be very helpful, says Singles, who is a distinguished psychologist in orthopedics and rehabilitation at the University of Wisconsin.
Focusing elsewhere means the pain isn’t hogging all your attention. This could simply be focusing on other parts of the body one at a time to induce progressive relaxation or another activity such as reading or watching a movie.
“Positive distractions are very helpful because the more you focus on pain guaranteed the worse you’re going to feel,” she says.
Saying a mantra
As little as 30 seconds of using a mantra can dampen unpleasant sensations, says Ellen Slawsby, PhD, director of Pain Services at the Benson Henry Institute at Massachusetts General Hospital in Boston. Slawsby recommends a picking neutral or positive word or phrase rather than a sound.
imagine yourself on the beach or seeing your worries melt away. “The key is knowing what kinds of things are relaxing for you and envisioning that can be helpful,” says Slawsby. “Visualization can be great for arthritis patients to ease joint pain.”
You can imagine you’re in a warm bath with hands floating on the water. “Go through the whole imagery of going into the tub, your toes, ankles, knees, hip joint, lower back, middle back, shoulders,” she says. “Imagine the joints being warm and relaxed without the pressure of the regular planetary pull because you’re in the water. It gives you a buoyancy.”
Activating pressure points
Also known as self massage, applying pressure to areas that hurt, especially if it’s a tension headache or muscle pain, can be very beneficial, says Slawsby. It’s not clear why it works but it does.
Some people think that soothing messages from the massage counteract pain messages. Or it could be that the pressure reduces muscle tension, which is the culprit behind many different types of pain.
Try to switch to more positive thoughts and, in particular, avoid catastrophizing or imagining the worst.
Listening to music
Music can provide a welcome distraction, but also offers so much more. One study, which looked at rheumatoid arthritis patients and others suffering from chronic pain, found that listening to music for one hour over one week subdued pain, depression, and disability while increasing feelings of power.
Getting your thoughts and feelings on paper has been shown to relieve pain in many different populations. It can even enhance immune function. James W. Pennebaker, PhD, a leading researcher in the field, recommends writing before bed for a minimum of 15 minutes a day for at least three or four days.
Some possible topics: Something that you are thinking or worrying about too much, something you’ve been avoiding, or something you think is affecting your life in an unhealthy way.
Tapping into your creativity
Art therapy is gaining more credibility in medical settings, with some hospitals having dedicated therapy—often geared to children.
But the technique works in adults as well, with one study reporting that one hour of art therapy relieved physical and psychological symptoms in people living with HIV/AIDS.
The same group of researchers earlier found that playing with clay, glitter glue, yarn, beads, colored pencils, and an array of other art supplies relieved symptoms of pain and anxiety in cancer patients.
The adage “laughter is the best medicine” is no joke. A pilot study conducted at UCLA found that children and adolescents who watched humorous videos while their hands were soaking in frigid water were better able to tolerate the pain.
Another study attributed the effects of laughter on the release of endorphins, nature’s own analgesic.
