Think ahead, live longer

Wednesday, March 18th, 2009

This article published in ABC Health and Wellbeing is very much in keeping with thoughts from Cognitive Hypnotherapy – imagine the future you want, and then allow the unconscious mind to guide you towards it (whilst doing a little work along the way to help the process, of course!

The Pulse

by Peter Lavelle

People who plan ahead and think of the future are often healthier than those living for the here-and-now, argues a prominent US psychologist. Published 12/03/2009 

Do you live for the present, without worrying about tomorrow? Do you view the future through the prism of what’s happened to you in the past? Or do you keep one eye on the future in everything you do? Whichever you do, will impact directly on your health, argues US psychologist Philip Zimbardo. Zimbardo, Emeritus Professor at Stanford University, is the author of a new book The Time Paradox: The New Psychology of Time That Will Change Your Life. In it he argues people tend to make decisions based on whether they are orientated to the past, present or future. Some people are dominated by their past experiences and this influences how they make decisions now. These past experiences may be positive – family or cultural traditions or rewards for good things they’ve done in the past – or they may be negative events – past traumas influencing what they do in the present. People with post-traumatic stress syndrome have been negatively influenced by their past. Other people are orientated towards the present. They seek immediate rewards, without much thought for the future, and are influenced by their body sensations and physiology (hunger, thirst, desire for sex etc) or what their peer group is doing. Rather than plan ahead, these people often rely on luck or fate and they tend to have lower levels of impulse control and emotional stability. Zimbardo says people who have addictions are very often present-thinkers, as are gamblers or those who run up credit card debts. Then there are people who are focused on the future, these people think of the consequences of their actions. They are good at controlling their egos and impulses; are conscientious, consistent, non-aggressive, and have low levels of depression. In reality we all have a bit of past, present and future orientation, but we tend to be skewed to one and underuse the others, says Zimbardo. He argues your time perspective may depend on many things including the climate you live in, your religion, your education (more educated people tend to be more future thinking), your gender (women are more future thinking than men), what income you earn (poorer people tend to be more present-orientated) and your age. In fact, we are all born present-thinkers, but become more focused on the future as we age, often in response to pressure from society. Many of the stories, nursery rhymes and games we play as kids encourage us to be forward-thinking; as does school and higher education. But being totally future-oriented is also unhealthy, says Zimbardo. Excessive emphasis on the future causes anxiety in the here and now, (as to how things might turn out) which can lead to social isolation and performance anxiety (especially anxiety about sexual performance). This is where present-oriented thinkers have some advantages; they make friends easily (being the ‘life of the party’), they are creative thinkers and have plenty of energy to enable them to achieve their goals. Being past-oriented (especially if your past experiences are positive) also has some advantages. Your family or culture may give you a sense of identity and continuity and provide you with positive role models. So what we need is a balance of all three ways of thinking. Healthy future So what does all this have do with your health? Zimbardo suggests there’s a very strong correlation between future orientation and health – the more future-oriented you are, the healthier you’ll be and the longer you’re likely to live. Research published in the British Journal of Health Psychology last month supports Zimbardo’s theory. Studies show people who are future thinkers tend to use drugs less, and adopt safe sex practices, the researchers say. Future thinkers also tend to be less likely to smoke and have healthier body mass indices, they conclude, after studying a group of about 400 people who answered questions about their health and lifestyles and who also underwent psychological testing including the Zimbardo Time Perspective Inventory (ZPTI) – a questionnaire Zimbardo helped develop in 1999 to test how people’s time perspective affects their decision making. (If you’re curious about which orientation you might be, do Zimbardo’s inventory yourself – just follow the link at the bottom of this page). On the other hand, other studies have shown that future-thinking doesn’t have much effect on whether people will get vaccinated, or stick to taking blood pressure or cholesterol medications. So future-thinking seems to be a factor in changing some behaviour but not others, say the British researchers. Getting the message out One of the challenges facing policymakers and health workers in preventative health is how to get people to forego junk food, drugs and alcohol, a sedentary lifestyle, for rewards that may be long into the future. But some public health messages may not be reaching their intended audience, says Zimbardo. Anti-drug campaigns warning of the future health risks of drug taking, for example, may be doomed to failure because their target audience (people inclined to use drugs) often live in the present and won’t listen to messages about the future. Peter Sainsbury, an Adjunct Professor of Public Health at Sydney University, agrees one of the challenges of mounting an effective public health program is to get people to change their behaviour for long-term benefits. “So you may need to give them a reason to change their behaviour in the here-and-now,” says Sainsbury. “For example, smokers may be more likely to quit if they think there’s an immediate benefit – better smelling breath, more success with the opposite sex for example, rather than the promise of better health twenty years from now.”

IVF and fertility problems? Just relax

Just one of the ways Cognitive Hypnotherapy can help for fertility. See www.anitamitchell.co.uk for further details.

Women struggling to have a baby are being told their problem may be all in the mind, with some happy results Rachel Carlyle Sophia Mackintosh is all too aware that she is a walking stereotype. After two miscarriages and a failed IVF attempt, she decided to give up trying for a baby and buy a dog instead. With Lulu happily installed in their newly renovated house in Islington, North London, Mackintosh and her husband, James, launched themselves wholeheartedly into the adoption process. Then, five years after that first traumatic miscarriage, she discovered that she was pregnant. Hers is a familiar story of the type gleefully recounted by those who believe that women today try too hard to get pregnant. Mackintosh agrees – she believes that during those five years her mind was sabotaging her chances. “I became obsessed. Every month I would pee on an awful lot of sticks and be disappointed each time that I was not pregnant,” she says. “But, deep down, there was relief that at least I would not spend the next 12 weeks panicking about having another miscarriage.” After beginning the adoption process, Mackintosh, a charity director, began seeing a fertility counsellor. “I began to see my body in a positive way again, and she taught me to be calmer about life and confident that I would have a baby one day. And because we were about to adopt, James and I weren’t trying quite so desperately to conceive.” After the fifth session, she was pregnant, and now, at the age of 40, she has two sons, aged 3 and 1 (plus Lulu the dog). Mackintosh’s story is one of 15 collected by Michaela Ryan for a book, Trying to Conceive (Vermilion, £10.99). Related Links IVF advance promises leap in success rates Our IVF journey Top ten ways to boost your fertility The idea that the mind has a large part to play in fertility is also advocated by the midwife Zita West, who last month launched a Manage Your Mind programme at her London clinic. Each hour-long session costs £110 and a course of one to six sessions is recommended. Techniques include guided relaxation, art therapy, hypnotherapy and cognitive behaviour therapy (turning negative thoughts into positive ones). West says: “I know it makes me sound woolly, which I most certainly am not, but I have been doing this for a long time and I’m convinced that the mind-body link is crucial.” She says that “unexplained infertility” accounts for up to 23per cent of infertility cases, and 80 per cent of these could be down to the mind. The cause could be a subconscious fear of having a baby or the stress that comes from worrying about being unable to conceive. “Negative messages from the past are very important; they stay with you.” Although evidence for “mindset infertility” is scant, there is a growing acceptance that stress can affect the part of the brain governing reproductive hormones. “Basically, when an animal is stressed, it sends signals to suppress reproduction,” says Dr Jacky Boivin, a Cardiff University psychologist who specialises in infertility. “This has been proved in rats, sheep, cows and bulls, but in humans it’s more difficult to prove.” The Boston obstetrician Dr Alice Domar, a pioneer of the mind-body connection, has carried out several studies. In one, she recruited 185 IVF patients; a third did her ten-week mind-body programme, a third joined a support group and the remaining third had no extra support. She found that 55per cent of the mind-body group , 54 per cent of the support group and 20 per cent of the control group conceived. Seeta Rashid was 28 when she and husband, Tahir, began trying for a baby. After a year nothing had happened and medical investigations proved inconclusive, so the couple joined the estimated 400,000 people in Britain with “unexplained infertility”. After three failed attempts at intrauterine insemination (IUI), where the sperm is injected into the uterus, Rashid joined Cradle, a local support group in Renfrewshire. “Infertility consumes you; it puts your life on hold. Every time you go out, all you see are pregnant women or women pushing prams. You think everyone in the world is pregnant except you,” she says. At Cradle she learnt relaxation, changed her diet, took up yoga and studied techniques to challenge negative thinking. Soon after, she began her fourth IUI, which succeeded, and the couple’s daughter, Hema, was born in September, 2005. While on maternity leave, Rashid and a fellow Cradle member, the geneticist Sam MacCuish, persuaded Domar to visit Scotland. The pair secured Lottery funding and were trained in Domar’s ten-session mind-body programme. They have run one pilot and one “proper” course, each for six IVF couples who had previous miscarriages and/or failed treatments. From the second programme, five of the women got pregnant, and the sixth decided not to go ahead with treatment – an 83 per cent success rate. While running the course, Rashid put the ideas into practice, and naturally conceived her son, Gibran, who celebrated his first birthday last weekend. “I can’t say for certain what made the difference, but the mind is a very powerful thing and we should never underestimate it.” Many doctors remain sceptical, however. “Just look at some of the stressful states that people have lived in – the Second World War, starvation in Africa – yet women still conceived easily,” says Richard Kennedy, a fertility specialist at University Hospital Coventry and secretary-general of the International Federation of Fertility Societies. He won’t dismiss a mind-body link completely, however. “You hear of couples who get to the point where their doctor says that there is nothing more that can be done, so they decide to get a dog or spend their money on a world cruise. They relax – then they get pregnant naturally. But to my knowledge there is no research on that link.”

Overthinking 'disrupts golf putt'

Friday, January 30th, 2009

Just ask Tiger, he’s ‘gone’ when he makes a shot. Find out how cognitive hypnotherapy  and NLP can help reduce your handicap www.anitamitchell.co.uk.

Found on the BBC News website:

Golfers who think too much about their technique between shots could be seriously affecting their performance, a study has suggested.

St Andrews University and US scientists said they had established that too much analysis made the golfer’s game worse.

They said thinking too much about the previous shot can disrupt performance.

In total, 80 golfers were given shots to practise until they got it right. Those who discussed their putting between strokes took twice as long.

The study suggested talking could “overshadow” motor skills Golfers who think too much about their technique between shots could be seriously affecting their performance, a study has suggested. St Andrews University and US scientists said they had established that too much analysis made the golfer’s game worse. They said thinking too much about the previous shot can disrupt performance. In total, 80 golfers were given shots to practise until they got it right. Those who discussed their putting between strokes took twice as long. The study found that when the mix of skilled and novice golfers tried again, those who had discussed the shot took longer to get the shots right as those people who had spent a couple of minutes engaged in other, unrelated activities. Simply describing one’s putting skill after it has been executed can be incredibly disruptive to future putting performance Prof Michael Anderson St Andrews University Psychology Professor Michael Anderson, from St Andrews University, said: “This effect was especially dramatic in skilled golfers who were reduced to the level of performance of novices after just five minutes of describing what they did. “Novices, by contrast, were largely unaffected, and perhaps even helped a little, by verbally describing their movements. “It’s a fairly common wisdom in sport that thinking too much hurts performance; during a game it can be an obvious distraction. “However, what we found surprising is that simply describing one’s putting skill after it has been executed can be incredibly disruptive to future putting performance.” He said overthinking did not seem to affect novices because “they probably haven’t developed enough skills to forget in the first place” and claimed that top professionals would be less susceptible as they were very focused in their approach. The researchers think the loss of performance was due to an effect called verbal overshadowing, which makes the brain focus more on language centres rather than on brain systems that support the skills in question. The study, which also involved the University of Michigan, marks the first time researchers have claimed to demonstrate that verbal overshadowing can adversely affect motor skills. Prof Anderson said the findings may have consequences for people who take part in other sports. “This observation may have repercussions for athletes who depend on effective mental techniques to prepare for events,” he added. “Moreover, those who teach golf, or any motor skill, might be undoing their own talent in the process.”

Slow Starvation of Brain Triggers Alzheimer's

Saturday, January 10th, 2009

A slow starvation of the brain over time is one of the major triggers of the biochemistry that causes some forms of Alzheimer’s, according to a new study that is helping to crack the mystery of the disease’s origins.

An estimated 10 million baby boomers will develop Alzheimer’s in their lifetime, according to the Alzheimer’s Association. The disease usually begins after age 60, and risk rises with age. The direct and indirect cost of Alzheimer’s and other dementias is about $148 billion a year.

Robert Vassar of Northwestern University, the study’s lead author, found that when the brain doesn’t get enough of the simple sugar called glucose — as might occur when cardiovascular disease restricts blood flow in arteries to the brain — a process is launched that ultimately produces the sticky clumps of protein that appear to be a cause of Alzheimer’s.

Working with human and mice brains, Vassar discovered that a key brain protein is altered when the brain’s supply of energy drops. The altered protein, called eIF2alpha, increases the production of an enzyme that, in turn, flips a switch to produce the sticky protein clumps.

“This finding is significant because it suggests that improving blood flow to the brain might be an effective therapeutic approach to prevent or treat Alzheimer’s,” Vassar said.

The best ways to improve blood flow to the brain and thereby reduce the chances of getting Alzheimer’s is to reduce cholesterol intake, manage high blood pressure and exercise, especially entering mid-life.

“If people start early enough, maybe they can dodge the bullet,” Vassar said. For people who already have symptoms, vasodilators, which increase blood flow, may help the delivery of oxygen and glucose to the brain, he added. The study is published in the Dec. 26 issue of the journal Neuron.

No candy bars

When it comes to prevention of Alzheimer’s, eating candy bars is not the solution to improving the flow of blood glucose to the brain, Vassar told LiveScience.

A decreasing blood flow to the brain happens over time, as we age, and that slowly starves the brain of glucose. This could be a general aging phenomenon, or it could be that some individuals are particularly prone to it, Vassar said. Also, decreased blood flow is associated with atherosclerosis, or hardening of the arteries, and hypertension, or high blood pressure.

“We need to improve our cardiovascular health, not eat more sugar,” Vassar said. “What is coming out in terms of the epidemiological studies is that exercise during mid-life is one of the best prevention strategies for Alzheimer’s disease, so people should stay active physically, and they should watch their diets and reduce cholesterol intake, because cholesterol contributes to atherosclerosis, and that is true for the heart and the rest of the body as well as for the brain.”

Vassar said it also is possible that drugs could be designed to block the elF2alpha protein that begins the formation of the protein clumps, known as amyloid plaques.

Earlier Alzheimer’s findings

Ten years ago, Vassar discovered the enzyme, BACE1, that was responsible for making the sticky, fiber-like clumps of protein that form outside neurons and disrupt their ability to send messages.

But the cause of the high levels of the protein in people with the disease has been unknown. Vassar’s new study now shows that energy deprivation in the brain might be the trigger starting the process that forms plaques in Alzheimer’s.

Vassar said his work suggests that Alzheimer’s disease may result from a less severe type of energy deprivation than occurs in a stroke. Rather than dying, the brain cells react by increasing BACE1, which may be a protective response in the short term, but harmful in the long term.

“A stroke is a blockage that prevents blood flow and produces cell death in an acute, dramatic event,” Vassar said. “What we are talking about here is a slow, insidious process over many years where people have a low level of cardiovascular disease or atherosclerosis in the brain. It’s so mild, they don’t even notice it, but it has an effect over time because it’s producing a chronic reduction in the blood flow.”

Vassar said when people reach a certain age, some may get increased levels of the enzymes that cause a build-up of the plaques. “Then they start falling off the cliff,” he said.

'Mind's Eye' Influences Visual Perception

Saturday, July 5th, 2008

This was posted on ScienceDaily, showing scientific proof of what NLP has known for about 25 years.

ScienceDaily (July 4, 2008) — Letting your imagination run away with you may actually influence how you see the world. New research from Vanderbilt University has found that mental imagery—what we see with the “mind’s eye”—directly impacts our visual perception.

“We found that imagery leads to a short-term memory trace that can bias future perception,” says Joel Pearson, research associate in the Vanderbilt Department of Psychology. and lead author of the study. “This is the first research to definitively show that imagining something changes vision both while you are imagining it and later on.”

“These findings are important because they suggest a potential mechanism by which top-down expectations or recollections of previous experiences might shape perception itself,” Pearson and his co-authors write.

It is well known that a powerful perceptual experience can change the way a person sees things later. Just think of what can happen if you discover an unwanted pest in your kitchen, such as a mouse. Suddenly you see mice in every dust ball and dark corner—or think you do. Is it possible that imagining something, just once, might also change how you perceive things?

“You might think you need to imagine something 10 times or 100 times before it has an impact,” says Frank Tong, associate professor of psychology and co-author of the study. “Our results show that even a single instance of imagery can tilt how you see the world one way or another, dramatically, if the conditions are right.”

To test how imagery affects perception, Pearson, Tong and co-author Colin Clifford of the University of Sydney had subjects imagine simple patterns of vertical or horizontal stripes, which are strongly represented in the primary visual areas of the brain. They then presented a green horizontal grated pattern to one eye and a red vertical grated pattern to the other to induce what is called binocular rivalry. During binocular rivalry, an individual will often alternately perceive each stimulus, with the images appearing to switch back and forth before their eyes. The subjects generally reported they had seen the image they had been imagining, proving the researcher’s hypothesis that imagery would influence the binocular rivalry battle.

Additional experiments found that the effect of imagery on perception was approximately the same as showing the research subject a faint representation of one of the patterns between trials. Stronger shifts in perception were found if subjects either viewed or imagined a particular pattern for longer periods of time. They found that both imagery and perception can lead to a build-up of a “perceptual trace” that influences subsequent perception.

Pearson, Clifford and Tong also discovered that changing the orientation of the image from what had been imagined greatly reduced the impact of imagery on perception. Because orientation is processed in early visual areas, this suggests that imagery’s interaction with perception may occur at early stages of visual processing.

The new findings offer an objective tool to assess the often-slippery concept of imagination.

“It has been very hard to pin down in the laboratory what exactly someone is experiencing when it comes to imagery, because it is so subjective,” Tong says. “We found that the imagery effect, while found in all of our subjects, could differ a lot in strength across subjects. So this might give us a metric to measure the strength of mental imagery in individuals and how that imagery may influence perception.”

The findings may also help settle a longstanding debate in the research community over whether mental imagery is visual—that one imagines something just as one sees it—or more abstract.

“More recently, with advances in human brain imaging, we now know that when you imagine something parts of the visual brain do light up and you see activity there,” Pearson says. “So there’s more and more evidence suggesting that there is a huge overlap between mental imagery and seeing the same thing. Our work shows that not only are imagery and vision related, but imagery directly influences what we see.”

The research was funded by the National Institutes of Health, an Australian Research Council Discovery Grant and an Australia National Health and Mental Research Council Martin Fellowship. Pearson is a member of the Vanderbilt Vision Research Center. Tong is a member of the Vanderbilt Vision Research Center and the Vanderbilt Center for Integrative and Cognitive Neuroscience.
