Treating Alzheimer’s Disease

Are scientists close to finding a cure?

The number of Americans suffering from Alzheimer's, a degenerative brain disease, is projected to more than double by 2050, from 5.3 million today to 13.8 million. At the same time, as Baby Boomers age and medical expenses rise, the cost of treating and caring for people with the disease is expected to rise fivefold to $1.1 trillion. No treatment can yet prevent or cure Alzheimer's. However, advances in brain science and diagnostic technologies are creating breakthroughs unimagined even a few years ago. Rapidly expanding knowledge in genetics, neuroscience, biology and computing is leading to clinical trials on potential new drug therapies, research on how to prevent the disease and new tests to help diagnose it — perhaps even before symptoms appear. Scientists are debating whether the main hypothesis of what causes the disease — a buildup of amyloid protein into plaques that kill nerve cells in the brain — is correct. Patient advocates say federal Alzheimer's research is underfunded, but Congress is clearing the way for more research funds.

Al Capone

    Born in 1899 in Brooklyn, New York, to poor immigrant parents, Al Capone went on to become the most infamous gangster in American history. In 1920 during the height of Prohibition, Capone’s multi-million dollar Chicago operation in bootlegging, prostitution and gambling dominated the organized crime scene. Capone was responsible for many brutal acts of violence, mainly against other gangsters. The most famous of these was the St. Valentine’s Day Massacre in 1929, in which he ordered the assassination of seven rivals. Capone was never indicted for his racketeering but was finally brought to justice for income-tax evasion in 1931. After serving six-and-a-half years, Capone was released. He died in 1947 in Miami. Capone’s life captured the public imagination, and his gangster persona has been immortalized in the many movies and books inspired by his exploits.

W.H.O. calls ‘vaccine hesitancy’ an increasing concern globally

Rick Gladstone

August 18, 2015

    The World Health Organization warned Tuesday of what it called the growing problem of “vaccine hesitancy,” when people delay or refuse vaccines for themselves or their children. In a statement on its website, the organization called the problem “a growing challenge for countries seeking to close the immunization gap.” Globally, the organization said, one in five children still do not receive routine lifesaving immunizations, and 1.5 million children die each year of diseases that could have been thwarted by vaccines.

Social life in youth may impact health decades later

Robert Preidt

August 6, 2015

    Having good social connections at age 20 can lead to improved well-being later in life, a new study suggests. Previous research has shown that people with poor social links are at increased risk for early death. “In fact, having few social connections is equivalent to tobacco use, and [the risk is] higher than for those who drink excessive amounts of alcohol, or who suffer from obesity,” study author Cheryl Carmichael, who conducted the study while a doctoral candidate at the University of Rochester in New York, said in a university news release.

    The study included 133 people who enrolled when they were 20-year-old college students in the 1970s. The participants kept track of their daily social interactions at ages 20 and 30. At age 50, they completed an online survey about the quality of their social lives and emotional well-being, including questions about loneliness and depression, and their relationships with close friends.

    The findings showed that frequent social interactions at age 20 and good-quality relationships – defined as intimate and satisfying – at age 30 were associated with higher levels of well-being at age 50. The study findings were published in a recent issue of the journal Psychology and Aging.

    A high number of social interactions at age 20 are beneficial later in life because they help young adults determine who they are, the researchers said. “It’s often around this age that we meet people from diverse backgrounds, with opinions and values that are different from our own, and we learn how to best manage those differences,” said Carmichael, now an assistant professor of psychology at Brooklyn College. “Considering everything else that goes on in life over those 30 years – marriage, raising a family and building a career – it is extraordinary that there appears to be a relationship between the kinds of interactions college students and young adults have and their emotional health later in life,” she concluded.

How stress affects your health

Stress: We've all felt it. Sometimes stress can be a positive force, motivating you to perform well at your piano recital or job interview. But often — like when you're stuck in traffic — it's a negative force. If you experience stress over a prolonged period of time, it could become chronic — unless you take action.

Even short-lived, minor stress can have an impact. You might get a stomach-ache before you have to give a presentation, for example. More major acute stress, whether caused by a fight with your spouse or an event like an earthquake or terrorist attack, can have an even bigger impact.

Multiple studies have shown that these sudden emotional stresses — especially anger — can trigger heart attacks, arrhythmias and even sudden death.

When stress starts interfering with your ability to live a normal life for an extended period, it becomes even more dangerous. The longer the stress lasts, the worse it is for both your mind and body. You might feel fatigued, unable to concentrate or irritable for no good reason, for example. But chronic stress causes wear and tear on your body, too.

Stress can make existing problems worse. In one study, for example, about half the participants saw improvements in chronic headaches after learning how to stop the stressproducing habit of “catastrophizing,” or constantly thinking negative thoughts about their pain. Chronic stress may also cause disease, either because of changes in your body or the overeating, smoking and other bad habits people use to cope with stress. Other forms of chronic stress, such as depression and low levels of social support, have also been implicated in increased cardiovascular risk. And once you're sick, stress can also make it harder to recover. One analysis of past studies, for instance, suggests that cardiac patients with so-called “Type D” personalities — characterized by chronic distress — face higher risks of bad outcomes.

Technology isn’t working

The digital revolution has yet to fulfil its promise of higher productivity and better jobs

      If there is a technological revolution in progress, rich economies could be forgiven for wishing it would go away. Workers in America, Europe and Japan have been through a difficult few decades. In the 1970s the blistering growth after the second world war vanished in both Europe and America. In the early 1990s Japan joined the slump, entering a prolonged period of economic stagnation. Brief spells of faster growth in intervening years quickly petered out. The rich world is still trying to shake off the effects of the 2008 financial crisis. And now the digital economy, far from pushing up wages across the board in response to higher productivity, is keeping them flat for the mass of workers while extravagantly rewarding the most talented ones.

      It seems difficult to square this unhappy experience with the extraordinary technological progress during that period, but the same thing has happened before. Most economic historians reckon there was very little improvement in living standards in Britain in the century after the first Industrial Revolution. And in the early 20th century, as Victorian inventions such as electric lighting came into their own, productivity growth was every bit as slow as it has been in recent decades.

Rio 2016 unveils innovative Olympic torch

The innovative design, which is _________________ by the warmth of the Brazilian people, features moveable segments that expand vertically to reveal the colours of Brazil when the Olympic flame is passed from one torchbearer to another. The triangular shape of the torch, meanwhile, alludes to the three Olympic Values of excellence, friendship and respect, while the floating effect of its different segments represents the efforts of the athletes.
