Key concepts: College, Hypnosis and Anxiety

(NaturalNews) A lot is expected of today’s college students. They are under an enormous amount of pressure to succeed in academics. The pressure comes from themselves, parents, professors, and friends. This causes a lot of stress for students. Success in college is a stepping stone to being successful in a career after graduation, so students feel the need to perform at their full potential. It is important for struggling college students to seek help in reducing their stress with natural treatments such as hypnotherapy. For some students, the stress and anxiety of school and academics can become overwhelming. Stress affects students in many different ways. For some students, their grades start to suffer, which can affect their GPA in the long-run. Other students become so overwhelmed by stress that they drop out of college. According to the 2000 census, 50% of the population in the United States over the age of 25 attended college. However, only 60% of those who attended college earned an associate, bachelor, or graduate degree. This means that 40% did not finish college for various reasons. Sapp (1990) studied the role hypnosis plays on treating test-anxiety in college students. The participants in the study were randomly divided into two groups. One group served as the control group and received no form of treatment. The other group received cognitive-behavioral hypnosis. The researcher evaluated the effects of hypnosis in improving academic performance and decreasing test anxiety. Both groups were enrolled in a demanding psychology course. All students were evaluated based on their midterm grade and anxiety levels. The hypnosis group reported a significant reduction in test anxiety and improvement in academic achievement. Both groups were evaluated 6 weeks after the end of the course and the hypnosis group was found to have maintained their hypnosis treatment gains in achievement and reduction in anxiety. Cognitive behavioral hypnosis is a highly effective form of treatment that helps students improve performance and reduce anxiety. Carrese (1998) outlines the benefits of teaching self-hypnosis to college freshman. The researcher describes the steps taught to students, including relaxation techniques and the usage of imagery. Self-hypnosis was able to help the college freshman cope with stress and the pressures of college. Whether cognitive-behavioral hypnosis is used or self-hypnosis is used, hypnotherapy is a very effective form of treating stress and anxiety in college students. Having the ability to better manage stress not only improves their academic performance in college, but will continue to help them cope with stress in other situations throughout their lives.

Building Blocks of Bliss

Thursday, April 9th, 2009

Interesting how after all the research done on the subject, we don’t really know what the key to happiness is. It would seem that we can’t just put it down to one or two things, but it looks like we might be getting closer to knowing … This article from Psychology Today explains the latest findings.
An optimistic outlook and strong interpersonal bonds are key to happiness.

By: Anna Schneider-Mayerson

If Tolstoy was correct in his famous statement that happy families are essentially “happy in the same way,” researchers have yet to find that common denominator. When it came to analyzing extremely happy college students, researchers were reduced to triangulation: The very happy are not more religious, nor do they exercise or sleep more than the rest of us. True, they spend more time socializing and receive the highest self and peer ratings on the quality of their relationships.

But some unhappy students were equally social and boasted satisfactory relationships, according to Martin Seligman, Ph.D., a professor of psychology at the University of Pennsylvania, and Edward Diener, Ph.D., a psychology professor at the University of Illinois at Urbana-Champaign, who compared college students in the top 10 percent on bliss indices to those whose moods were average to miserable. The researchers liken happiness to “symphonic music necessitating many instruments, without any one being sufficient for the beautiful quality.”

Diener describes the top-rated students as “happy most of the time, rather than intensely happy a lot.” Interestingly, 6 of the 22 extremely happy students exhibited a degree of hypomania indicative of “active, energetic people who are very self-confident.”

While optimism is not tantamount to happiness, optimists and the very happy both have strong social networks. This support system, as well as coping mechanisms such as the “every cloud has a silver lining” mentality, known as “positive reinterpretation and growth,” enables optimists to better weather stress and depression.

“Most personality psychologists examine the benefits of optimism in terms of what optimists do for themselves,” explains Ian Brissette, Ph.D., an assistant professor of psychology at Rutgers University, who studied 89 college freshmen during their first semester at school. But “benefits may also stem from the ability to develop social support,” says Brissette. “Optimists experience better mental health not only because of what they do but because of what others do for them.” The results were published in the Journal of Personality and Social Psychology.

Video Games Can Encourage Positive Behavior, Too

Saturday, March 28th, 2009

With so much bad press for video games and the people who partake in them, this article  from Miller-McCune makes a refreshing change

 By: Tom Jacobs  |  March 27, 2009  |  01:07 PM (PDT)  |  

 

If violent video games encourage violent behavior, as a series of studies suggests, do prosocial games — those that reward helpful behavior — inspire players to act in more constructive, cooperative ways? A newly published paper, featuring studies of three different age groups in three different countries, suggests the answer is yes.

“Video games are not inherently good or bad,” concludes the team of 12 researchers led by psychologist Douglas Gentile of Iowa State University. Their findings suggest this popular form of entertainment “can have both positive and negative effects.”

The paper, published in the Personality and Social Psychology Bulletin, begins with a survey of secondary school students in Singapore (adolescents in the equivalent of seventh or eighth grade). They listed their favorite games, the number of hours they spend playing them each week and how often the games involve a) helping others, or b) hurting or killing others.

They were then asked a series of questions to measure their emotional awareness and empathy for others. After controlling for several variables, “prosocial game exposure was positively related to prosocial behavior,” the researchers report.

The second survey was of fifth-, eighth- and eleventh-grade students in Japan. They were asked how often in the past month they had played games in which characters help troubled people, or games in which friendship or a positive parent-child relationship was featured.

Finally, the youngsters were asked how often in the previous month they had acted in one of four specific helpful ways (such as “I helped a person who was in trouble”). The researchers discovered a strong relationship between playing prosocial games and self-reported prosocial behavior.

For the third study, the researchers conducted an experiment using 161 American college students, who were randomly assigned to play specific parts of one of six video games. Two of the games were violent (Ty2 and Crash Trinsanity), two were neutral (Pure Pinball and Super Monkey Ball Deluxe), and two were deemed prosocial: Chibi Robo, in which the goal is to make your family happy by cleaning up and helping out with the chores; and Super Mario Sunshine, in which players gain points by cleaning up a polluted island.

After playing one of the games for 20 minutes, participants were asked to assign a partner 11 puzzles to complete. They were told that if their partners completed 10 of the puzzles within 10 minutes, the partner would win a $10 gift certificate. They could choose puzzles from one of three difficulty levels, depending upon whether they were disposed to help their partner win the prize, or to place difficulties in his or her path.

The researchers found that “participants who played a prosocial game helped their partners significantly more than did either those who had played a violent game, or those who had played a neutral game.” Furthermore, “the violent gamers hurt their partners significantly more than did either those who had played a prosocial game or those who had played a neutral game.”

Taken together, the three studies found that “prosocial game play was significantly positively related to all four measured prosocial behaviors and traits” — helping behavior, cooperation and sharing, empathy and emotional awareness. These findings complement a 2008 study from Britain that found listening to songs with prosocial lyrics encourages charitable behavior.

According to Gentile and his colleagues, these results “make it clear how critical it is to separate amount of play from the content of play.” In other words, video game playing per se isn’t the issue: Rather, the important factor is the underlying messages contained in specific games.

“Content matters,” they conclude, “and games are excellent teachers.”

Visual learners convert words to pictures in the brain and vice versa

Friday, March 27th, 2009
This interesting article published in Science Centric on 26 March 2009 demonstrates why, as an NLP Learning Coach, I realise how important it is for us to learn in our prefered style. If a visual person only ever hears the voice of their teacher telling them the things they need to know, the visual person has to convert that teaching into visual images before they can fully understand it. This makes twice the work. Alternatively, the student may just loose interest in learning at all, because they haven’t learned the skill of converting the information yet. As an NLP Learning Coach, I help my clients know their prefered learning type, and then show how they can use that information to help them the most. See further details at www.anitamitchell.co.uk. Here’s the article.

A University of Pennsylvania psychology study, using functional magnetic resonance imaging technology to scan the brain, reveals that people who consider themselves visual learners, as opposed to verbal learners, have a tendency to convert linguistically presented information into a visual mental representation. The more strongly an individual identified with the visual cognitive style, the more that individual activated the visual cortex when reading words.

The opposite also appears to be true from the study’s results.

Those participants who considered themselves verbal learners were found under fMRI to have brain activity in a region associated with phonological cognition when faced with a picture, suggesting they have a tendency to convert pictorial information into linguistic representations.

The study was presented this week at the 16th Annual Cognitive Neuroscience Society Meeting.

Future research based on the findings from this study may be able to determine whether cognitive styles are something one is predisposed to or can learn. Depending on the flexibility with which one can adopt a style, educators could cater to one style over another to improve learning.

It has long been thought that propensities for visual or verbal learning styles influence how children acquire knowledge successfully and how adults reason in every-day life; however, there was no empirical link to this hypothesis from cognitive neuroscience.

‘Often, job applicants are required to offer opinion on whether they consider themselves visual or verbal learners,’ Sharon Thompson-Schill, professor in the Department of Psychology and a member of Penn’s Centre for Cognitive Neuroscience, said. ‘Some school districts even require students to wear buttons identifying themselves as visual or verbal learners. Until this study, however, there was no direct evidence linking these cognitive styles to specific neural systems in the brain.’

In the Penn study, visual and verbal cognitive styles were measured in 18 subjects by a self-report exam called the Verbaliser – Visualiser Questionnaire. The Wechsler Adult Intelligence Scale, a standard intelligence test used here to grade visual against verbal learning styles, then measured cognitive abilities. Participants subsequently participated in a functional magnetic resonance imaging experiment.

During the fMRI session, participants performed a novel psychological task, a more sophisticated version of the childhood board game Memory, involving both word-based and picture-based feature-matching conditions designed to permit the use of either a visual or a verbal processing style.

Results of the study demonstrated a pattern of activity in modality-specific areas of the brain that distinguished visual from verbal cognitive styles. The areas did correspond with prior knowledge of brain utilisation. During word-based tasks, activity in a functionally defined brain region that responded to viewing pictorial stimuli, the fusiform gyrus, correlated with self-reported visualiser ratings on the VVQ test.

In contrast, activity in a phonologically related brain region, the supramarginal gyrus, correlated with the verbaliser dimension of the VVQ during the picture-based condition. These findings suggest that modality-specific cortical activity underlies processing in visual and verbal cognitive styles.

Kids with ADHD May Learn Better by Fidgeting

Thursday, March 26th, 2009

This article published on March 25th 2009, in Time, Health & Science talks about a four year study which suggests that a better approach (than some of the medications currently prescibed)  for ADHD children (at least those who are not hyperactive to the point of breaking things) is to let them move around as much as they would like.

Cognitive Hypntherapy and NLP have long suggested that we need to work at our clients pace and allow them to do it their way, not our way. We, as therapists know that all behaviour has a purpose. It’s good to find our that studies back up our therories.

Here is the article. Hope you find it interesting.

By John Cloud

Like nose-picking and a preoccupation with feculence, the inability to sit still for long periods is a defining characteristic of childhood. But children with attention-deficit/hyperactivity disorder (ADHD) often squirm constantly, even when other kids can remain still. Many parents and teachers respond by trying to get ADHD kids, at any cost, to stop fidgeting. The assumption is that if they could just stop wriggling, they would be able to focus and learn.

But a new study suggests that a better approach for ADHD kids (at least those who are not hyperactive to the point of breaking things) is to let them move all they want. That’s because many kids use their movements — like swiveling in a chair or folding a leg underneath themselves and bouncing in a desk seat or repeatedly lolling and righting their head — the way many adults use caffeine: to stay focused. In other words, it may be that excessive movement doesn’t prevent learning but actually facilitates it. (See the top 10 medical breakthroughs of 2008.)

Longtime ADHD researcher Mark Rapport supervised the study, which is set to be published in the Journal of Abnormal Child Psychology. Rapport, a professor at the University of Central Florida (UCF) in Orlando, notes that our activity level — how much we move around in everyday situations — is one of the most fixed parts of our personalities. If you are a fidgety kid, you will be a fidgety adult, even if you learn to manage your movements with caffeine, stress-reduction, a personal trainer or other adult accoutrements.

The idea that stimulants like caffeine (or Ritalin or even something stronger like cocaine) can help you sit still and pay attention seems counterintuitive at first. But that surprising fact lies at the heart of Rapport’s work: stimulants augment your working, or short-term, memory, where information is stored temporarily and used to carry out deliberate tasks like, say, solving a challenging math problem. ADHD kids have a hard time with working memory because they lack adequate cortical arousal, and Rapport believes that their squirms and fidgets help stimulate that arousal.

His study was small — just 23 boys ages 8 to 12 participated — but uncompromisingly meticulous; it took four years to complete. Twelve of the boys had an ADHD diagnosis. The other 11 were developing normally. All underwent a battery of tests at Rapport’s lab over four consecutive Saturdays.

Since I’ve always been fidgety, I asked Rapport if he wouldn’t mind putting me through the same tests he gave the boys. And so last week I found myself at the UCF Psychology Department, where a grad student affixed a device called an actigraph to my left wrist. Actigraphs look like digital watches and generate a signal each time they are moved, even slightly. They allow researchers to measure, quite precisely, a subject’s kinetic activity. The boys in Rapport’s experiments wore actigraphs on their ankles as well as their wrists because kids are often just as twitchy below the waist as above. (See the most common hospital mishaps.)

Wearing the actigraph, I sat before a computer in a small windowless room and took working-memory tests. For one test, I had to recite aloud a series of numbers that appeared on the screen. I was asked not only to remember the numbers but also to restate them in proper numerical order. So if I saw 4, then 3, then 1, then 8, I had to say, “One, three, four, eight.” Each series of numbers also included a random letter, which I had to state at the end: “One, three, four, eight, D.”

At first the test sounded simple, not least because I knew an 8-year-old could ostensibly complete it. But I found it quite difficult. Working-memory tests require intense concentration, and I was distracted because I was nervous. Rapport, several of his grad students, a UCF public relations official and a friend of mine were all watching me through an open doorway while I performed the tests. I ended up scoring worse than some of Rapport’s kids.

My experience of being nervous was instructive because it mimicked, in a way, the cognitive strain under which an ADHD kid takes such tests. ADHD compromises the brain’s executive functioning — its ability to master unexpected exercises. The same way I got nervous, ADHD kids get momentarily lost, their attention fractured for a few seconds. Think about when you’re reading and get to the end of a paragraph and realize you haven’t been paying attention: that’s what it’s like for ADHD kids, all the time. My actigraph scores confirmed that I wasn’t operating normally for a 38-year-old adult. Instead, during the experiment, I displayed the involuntary body movements of a typical 12-year-old boy. (See pictures of a diverse group of American teens.)

Rapport also conducted a control experiment with the boys in which they watched the pod-racing scene from Star Wars: Episode I — The Phantom Menace. He showed me a video of a couple of the boys watching the scene, and I was shocked: even the ADHD kids who had spun around endlessly during their cognitive tests sat perfectly still while they watched the pod race. The film clip required almost no working memory, no concentrated effort. The scene simply washed over the passively watching boys, none of whom had to move around to stay alert.

Which suggests a classroom technique for ADHD kids: Don’t overly tax their working memory. Rapport, who used to be a school psychologist, says the average teacher doesn’t understand how ADHD kids process information. “If you go into a typical classroom,” he told me, “you might hear, ‘Take out the book. Turn to page 23. Do items 1 through 8, but don’t do 5.’ And you’ve just given them four or five directions. The child with working-memory problems has dropped three of them, and so he’s like, ‘Page 23 — what I am supposed to do?’ ” Similarly, a parent might tell a kid, “Take my keys, go to the car, get your sister’s toy, and before you go, take the trash with you.” The ADHD kid will get to the car without remembering what else to do. Their instructions must be broken down carefully because their working memory is weak.

When I asked Rapport whether there’s a cure other than breaking down instructions, his answer was a bit depressing: no. ADHD is incurable. Drugs like Ritalin are a common answer for controlling the condition, which affects about 3% to 5% of children, but Rapport notes that they have proven to be only a limited solution. In the short term, they can facilitate a child’s ability to read — undoubtedly a crucial benefit — but Rapport says longitudinal studies have failed to show that Ritalin or other psychostimulants have consistent long-term behavioral effects. (Even if they did, another question would arise: Would you want to be dependent on a stimulant for the rest of your life?) Rapport hopes that his work will lead to the development of early behavioral and cognitive interventions that could help the youngest ADHD kids recognize, predict and somehow avoid ADHD’s concentration gaps.

Such research is in its infancy, though, and if you have a child with ADHD, it’s important to understand that he processes the world in a different way. He might be (literally) running circles around you, but that may be his way of paying attention.

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! See my website for details www.anitamitchell.co.uk):

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

Sunday, February 22nd, 2009

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

From

February 21, 2009

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.”

Sleep is needed to form memories

Saturday, February 14th, 2009

Sleep is something we all need! If  you need help having a good nights sleep take a look at my website to find out how I might help www.anitamitchell.co.uk.

First-of-its-kind study shows how brain connections strengthen during sleep

PHILADELPHIA – If you ever argued with your mother when she told you to get some sleep after studying for an exam instead of pulling an all-nighter, you owe her an apology, because it turns out she’s right. And now, scientists are beginning to understand why.

In research published this week in Neuron, Marcos Frank, PhD, Assistant Professor of Neuroscience, at the University of Pennsylvania School of Medicine, postdoctoral researcher Sara Aton, PhD, and colleagues describe for the first time how cellular changes in the sleeping brain promote the formation of memories.

“This is the first real direct insight into how the brain, on a cellular level, changes the strength of its connections during sleep,” Frank says.

The findings, says Frank, reveal that the brain during sleep is fundamentally different from the brain during wakefulness.  

“We find that the biochemical  changes are simply not happening in the neurons of animals that are awake,” Frank says. “And when the animal goes to sleep it’s like you’ve thrown a switch, and all of a sudden, everything is turned on that’s necessary for making synaptic changes that form the basis of memory formation. It’s very striking.”

The team used an experimental model of cortical plasticity – the rearrangement of neural connections in response to life experiences. “That’s fundamentally what we think the machinery of memory is, the actual making and breaking of connections between neurons,” Frank explains

In this case, the experience Frank and his team used was visual stimulation. Animals that were young enough to still be establishing neural networks in response to visual cues were deprived of stimulation through one eye by covering that eye with a patch. The team then compared the electrophysiological and molecular changes that resulted with control animals whose eyes were not covered. Some animals were studied immediately following the visual block, while others were allowed to sleep first.

From earlier work, Frank’s team already knew that sleep induced a stronger reorganization of the visual cortex in animals that had an eye patch versus those that were not allowed to sleep. Now they know why.

A molecular explanation is emerging. The key cellular player in this process is a molecule called N-methyl D-aspartate receptor (NMDAR), which acts like a combination listening post and gate-keeper. It both receives extracellular signals in the form of glutamate and regulates the flow of calcium ions into cells.

Essentially, once the brain is triggered to reorganize its neural networks in wakefulness (by visual deprivation, for instance), intra- and intercellular communication pathways engage, setting a series of enzymes into action within the reorganizing neurons during sleep.

To start the process, NMDAR is primed to open its ion channel after the neuron has been excited. The ion channel then opens when glutamate binds to the receptor, allowing calcium into the cell. In turn, calcium, an intracellular signaling molecule, turns other downstream enzymes on and off.

Some neural connections are strengthened as a result of this process, and the result is a reorganized visual cortex. And, this only happens during sleep.

“To our amazement, we found that these enzymes never really turned on until the animal had a chance to sleep,” Frank explains, “As soon as the animal had a chance to sleep, we saw all the machinery of memory start to engage.” Equally important was the demonstration that inhibition of these enzymes in the sleeping brain completely prevented the normal reorganization of the cortex.

Frank stresses that this study did not examine recalling memories. For example, these animals were not being asked to remember the location of their food bowl. “It’s a mechanism that we think underlies the formation of memory.” And not only memory; the same mechanism could play a role in all neurological plasticity processes.

As a result, this study could pave the way to understanding, on a molecular level, why humans need sleep, and why they are so affected by the lack of it. It could also conceivably lead to novel therapeutics that could compensate for the lack of sleep, by mimicking the molecular events that occur during sleep.

Finally, the study could lead to a deeper understanding of human memory. Though how and even where humans store long-lasting memories remains a mystery, Frank says, “we do know that changes in cortical connections is at the heart of the mystery. By understanding that in animal models, it will bring us close to understanding how it works in humans.”

 

Overthinking 'disrupts golf putt'

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

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.
