Too much sleep — either all at once or including naps during the day — may be just as bad as too little sleep

By Pamela Fayerman, Vancouver Sun July 17, 2012 10:15 AM
VANCOUVER — Seven hours — not more and not less — appears to be the magic number when it comes to how much sleep we need to keep our brains sharp and possibly avoid mental decline or even Alzheimer’s disease, according to the researchers of new studies presented in Vancouver Monday.

The preliminary (unpublished) research was discussed at the Alzheimer’s Association International Conference, being held here this week for about 4,000 researchers and Alzheimer’s experts.

Too much sleep — either all at once or including naps during the day — may be just as bad as too little; both are associated with mental decline. People who have disrupted sleep because of snoring and sleep apnea, or daytime sleepiness, are also more likely to experience mild cognitive impairment or dementia.

But whether sleep problems are a cause of mental decline, an effect, or both, is still open for more study, debate and proof.

“Is it a chicken or egg scenario? The truth is, we don’t yet know, and at this point, my guess is it’s bi-directional,” said researcher Elizabeth Devore, conceding that sleep problems aren’t exactly uncommon in people over 65. Indeed, more than half of those over that age have sleep disturbances that are also associated with many other health conditions like depression, stroke and cardiovascular disease — also risk factors for dementia.

However, Devore, of Brigham and Women’s Hospital in Boston, and other researchers, said that in all their studies, they took into account those confounding factors, and they still came up with results showing sleep and cognitive decline are linked.

“What we can say is that extreme sleep durations [too little or too much] may contribute to cognitive loss,” she said.

The research conducted by Devore and colleagues was based on data from more than 120,000 nurses who were aged 30 to 55 when they enrolled in the Nurses’ Health Study. They have answered questionnaires every few years and queries about sleep were added in 1986 and 2000. Cognitive testing was also done between 1995 and 2001, when the nurses were all at least age 70.

The researchers found that nurses who slept five hours a day or less had lower average memory and cognition scores than those who slept seven hours a day.

Those who slept at least nine hours a day also had lower cognition scores than those who slept seven hours.

An analysis of the results revealed that women whose sleep changed by at least two hours a day had worse mental function than those with no change in sleep time.

Dr. Kristine Yaffe of the University of California (San Francisco) said that in other studies on more than 1,300 women over age 75, those with sleep apnea or some other disordered breathing had more than twice the odds of developing cognitive impairment or dementia over a five-year study period, compared to those with no such breathing problems.

Women who had greater nighttime wakefulness, or insomnia, were more likely to get worse scores on cognition and verbal fluency tests. Sleep apnea (suspension of breathing during sleep) and snoring — which a third of the elderly experience — both decrease oxygen levels in the blood, causing a state called hypoxia.

Yaffe said she thinks hypoxia deserves far more study in the context of dementia. Referring to an unrelated study, she noted that in resuscitated cardiac arrest patients, there was a rise of blood amyloid levels immediately afterwards. Amyloid is a protein that accumulates in the brains of Alzheimer’s patients, causing sticky plaques. There may be a connection, then, between oxygen deprivation from something as banal as snoring, and dementia.

In light of the new findings, Devore said doctors should be assessing patients for sleep problems and referring them to sleep specialists who may be able to prescribe treatment to perhaps delay or prevent dementia. Machines called CPAPs have been shown in some small studies to improve cognition, she noted.

Presenting results from a continuing eight-year three-city study done on nearly 5,000 people in France, Dr. Claudine Berr told delegates that excessive daytime sleepiness, often necessitating napping, was an independent risk factor for cognitive decline.

By contrast, difficulty staying asleep was not associated with cognitive decline; in fact it appeared to have a protective effect, according to data from the National Institutes of Health and Medical Research study.

“It may be that excessive sleepiness, which was shown in our study to be associated with a 30-per-cent increased risk of cognitive decline, may be due to early stage brain lesions in areas [of the brain] associated with circadian rhythm abnormalities,” she said.

During the question and answer session with delegates, an American neurologist noted that some patients who are prescribed a hormone supplement called melatonin experience vastly improved sleep patterns. So instead of prescribing sleeping pills, doctors should think about recommending melatonin because of its safer profile.

There was general agreement that studies on melatonin and dementia prevention should be done and that doctors also need some standard prescribing guidelines for melatonin, which some people use for jet lag and insomnia.

Drug for diabetes may help improve brain injuries

Triggers neuron growth, potential to regenerate brain cells: study

By Sheryl Ubelacker, THE CANADIAN PRESS July 6, 2012

TORONTO — A drug commonly used to control Type 2 diabetes can help trigger stem cells to produce new brain cells, providing hope of a potential means to treat brain injuries and even neurodegenerative diseases like Alzheimer’s, researchers say.

A study by scientists at Toronto’s Hospital for Sick Children found the drug metformin helps activate the mechanism that signals stem cells to generate neurons and other brain cells.

“If you could take stem cells that normally reside in our brains and somehow use drugs to recruit them into becoming appropriate neural cell types, then you may be able to promote repair and recovery in at least some of the many brain disorders and injuries for which we currently have no treatment,” said principal investigator Freda Miller.

“This work is happening against a background of a lot of excitement in the stem cell field about the idea that since we now know that we have stem cells in many of our adult tissues, then perhaps if we could figure out how to pharmacologically tweak those stem cells, then perhaps we could help to promote tissue repair,” added Miller, a senior scientist at SickKids.

The research, published online Thursday in the journal Cell Stem Cell, involved lab-dish experiments using both mouse and human brain stem cells, as well as learning and memory tests performed on live mice given the drug.

Researchers started by adding metformin to stem cells from the brains of mice, then repeated the experiment with human brain stem cells generated in the lab. In both cases, the stem cells gave rise to new brain cells.

They then tested the drug in lab mice and found that those given daily doses of metformin for two or three weeks had increased brain cell growth and outperformed rodents not given the drug in learning and memory tasks.

One standard test involves a water maze in which the mice must swim around until they locate a hidden platform.

“And the remarkable thing is the mice that got the metformin, what they showed was increased flexibility in terms of the way they learned the location of things,” said Miller, explaining that the drug-treated mice had a greater ability to learn and remember.

“If you then, for example, moved the platform some place completely different, the metformin-treated animals were remarkably good at just saying, ‘OK, things have changed’ and learning the new thing and (were) much better than the controls (untreated mice).”

Miller said it was serendipity that led the team to conduct the study. About 18 months ago, they found a pathway known as PKC-CBP that signalled embryonic neural stem cells to make brain cells. At about the same time, some U.S. collaborators at Johns Hopkins University found the same pathway was activated by metformin in liver cells — the means by which the drug controls glucose levels that go awry in diabetes.

Based on those findings, Miller’s team thought metformin might activate the same pathway in neural stem cells.

“I love this story because it’s a classic example of how very basic research into how things work has led to a potential therapeutic endpoint,” she enthused.

One big bonus for researchers is that metformin has been well-tested and long prescribed for a number of diseases, including metabolic disorders in children. The drug also has been shown to have anti-cancer properties.

“The advantage again is that because metformin has been in people from seven until 107, we have lots of safety data on it, we know exactly what kinds of doses, et cetera, et cetera,” she said. “So that’s a really huge plus with moving forward.”

When it comes to progressive neurodegenerative diseases such as Alzheimer’s, Miller said there is a lot of excitement among scientists about finding a drug that could recruit stem cells to produce healthy neurons, “at least to give people just a bit longer healthier cognition, if you will.”

Metformin might be such a drug, but the difficulty is that stem cells age and diminish as people get older, so it’s unclear whether there would be adequate numbers of healthy brain stem cells to produce new neurons that would have a therapeutic benefit.

Still, it’s a possible and worthwhile line of investigation, she said.

Miller’s team is already in discussions with clinical colleagues about launching a pilot study to test metformin in young patients with acquired brain damage, either as result of treating a childhood brain tumour or from a traumatic head injury.

Such a study would try to determine if the drug could increase brain cell mass — using a functional MRI scan, for instance — and measuring any improvement in cognition and behaviour.

If approved, Miller said a pilot study could begin within the next year or so.

 

Too few patients call an ambulance after suffering a stroke: study

By Helen Branswell, THE CANADIAN PRESS July 12, 2012 1:02 PM

TORONTO — A new study on stroke care in Ontario highlights the fact that many people who suffer from a stroke are still waiting too long to seek medical attention.

The study says more than one in three people who experience a stroke don’t arrive at the hospital by ambulance.

It says calling 911 is the appropriate response to signs or symptoms of strokes.

Patrice Lindsay of the Canadian Stroke Network says ambulance staff assess patients for the telltale signs of stroke and will ensure a patient gets to the right hospital for care.

Small hospitals without CT scanners cannot diagnose strokes and give the clot-busting drugs that are crucial for minimizing the damage of a stroke.

Lindsay says ambulances will also call ahead so hospitals can arrange to free up CT scanners and have stroke teams on hand when the patient arrives.

Getting care quickly is critical with a stroke. The medical community uses the adage “time is brain” — referring to the fact that clot-busters received with the first few hours after a stroke can significantly reduce the damage a stroke patient sustains.

Lindsay, who is the stroke network’s director of performance and standards, says too often people don’t recognize the symptoms of stroke.

And many people downplay them, thinking the weakness or dizziness they feel will go away if they take a nap, she says.

“So the message we have to get out is a) recognize the symptoms and b) don’t take that chance. Because it could be the difference between walking out of the hospital of your own accord in a week or two versus ending up in permanent long-term care,” says Lindsay, who is a stroke survivor.

Symptoms of stroke include sudden weakness or loss of sensation in the face, arm or leg; difficulty speaking or understanding speech; sudden trouble with vision; sudden severe headache and dizziness or a sudden loss of balance.

The study, released by the Canadian Institutes for Health Information, looked at treatment of more than 62,000 stroke patients in Ontario from 2006-2007 through 2009-2010.

Taxi Saver Program Decision Reversed

TaxiSaver Program Update

July 11, 2012

TaxiSaver Program Update #2
Message from Nancy Olewiler, TransLink Board Chair
July 11, 2012

TransLink’s Board of Directors will maintain the TaxiSaver program, reversing its original decision to eliminate the program.

The original decision grew out of discussions on how to meet growing demand for custom transit services, including HandyDART. The goal was to redirect funding from TaxiSavers to improve these services. On May 30, the board put that decision on hold pending further engagement with a broader range of stakeholders. For the past several weeks, TransLink’s board and staff have been participating in meetings in the region to listen to concerns and discuss ideas. We have heard that the TaxiSaver program provides a valuable service to those in need, and is integral to making the transit system accessible for them.

Through this engagement, TransLink has also heard many good ideas and suggestions on how to make overall custom transit services better for those who need it most. We are committed to working closely with Access Transit’s Users’ Advisory Committee, persons with disabilities, seniors and other stakeholders from across the region on an ongoing basis to help find ways of improving these services. By continuing to listen to a broad spectrum of stakeholders on their ideas, TransLink’s goal is to continue to provide reliable, valuable and sustainable custom transit services.

Thank you to everyone who participated in the meetings, wrote and called us. We appreciate that you shared your insights with us. On behalf of the TransLink board, management and staff, we sincerely look forward to your continued feedback to help us improve accessibility of the public transit network for everyone.

Better armour, treatment saves more wounded soldiers, but many left in chronic pain

By Sharon Kirkey, Postmedia News April 18, 2012

When the pain hits hard, it feels as if Maj. Mark Campbell’s left foot has been set on fire.

Except, there is no foot. Campbell’s legs were blown off on a midday in June 2008, when a buried improvised explosive device was detonated beneath him during a Taliban ambush in Afghanistan.

His left leg was all but vaporized in the explosion; his right leg barely hung on by a few strands of shredded bone and tissue.

Today, he suffers phantom limb pain where his left leg below the knee used to be — an excruciating kind of torment so severe he needs methadone to manage it. He’s on maximum allowable doses of other pain medications, their list of side-effects long. “But I have no choice,” the 47-year-old father of two says. “It’s that, or I don’t want to live.”

As the nation’s largest military deployment since the Second World War ends, a new and constant companion will follow many wounded soldiers from the battlefield: Chronic, life-altering pain.

Leaders in Canada’s pain community say the unprecedented number of soldiers who survived injuries that in past wars would have killed them will need a high level of care in a country where pain is under-treated, and under-funded. U.S. doctors are reporting that half of Iraq and Afghanistan vets treated at military hospitals are experiencing some form of persistent and significant pain.

“We owe Canadian warriors the best pain care possible,” says Dr. Mary Lynch, director of research at the Pain Management Unit at the Queen Elizabeth II Health Sciences Centre in Halifax.

“But if the military has to rely on the civilian system of complex pain care, it will be grossly inadequate,” she said. Canadian civilians are facing waits of more than a year at specialized pain clinics. Vast areas of the country have no access at all.

A first-ever Canadian pain summit to be held next week in Ottawa will hear how a U.S. army-led task force on pain has led to an overhaul of how wounded soldiers are being treated, from the battlefield through rehabilitation once home. Specialized pain clinics are being set up at civilian and army medical centres across the U.S. that take a holistic approach. A military criticized for over-relying on opioids to manage pain — leading to high rates of addiction among injured soldiers — is now embracing acupuncture, meditation, yoga and other alternative therapies.

“We know that this is something that we need to be aggressively managing,” states Col. Chester (Trip) Buckenmaier III, program director for the U.S. Defense and Veterans Center for Integrative Pain Management.

“We’ve been talking about the ‘rock stars,’ if you will, of the conflict — those soldiers that have obvious injuries from an IED, for example, where there’s a limb missing,” he said.

“But the business of being in the military and the business of being in the war zone is hard, it’s hard on human beings,” Buckenmaier said. “We have these guys now in 40 pounds of body armour. They’re often running around with rucks that are another additional 50 pounds.

Soldiers are returning from war with severe back strain, joint pain and other musculoskeletal injuries, as well as constant headaches from exposure to multiple blasts.

“When a soldier comes back broken, that impacts everybody,” Buckenmaier said. “And until you’ve managed the pain adequately, they can’t focus on anything else. We really become the basest, the most base that we can be as human beings,” he said. “We’re animals. All you can think about is escaping the pain.”

Until the military began offering a combination of therapies, many people did just that by using opioids to excess, “because you could essentially send yourself into oblivion.”

While post-traumatic stress disorder and traumatic brain injury have been called the “signature injuries” of war, Buckenmaier says there is a third: Pain.

No land army in the history of warfare has achieved the level of survival as seen in the war in Afghanistan, he said.

“We have a less than 10 per cent died-of-wounds rate, and I’m pretty sure the Canadian military is enjoying a similar statistic.”

In the Second World War, 30 per cent of wounded troops died.

According to the Canadian Forces Surgeon General report in 2010, if a wounded CF soldier, sailor or airman makes it to the military hospital at the Kandahar Airfield with vital signs, they have a 97 per cent chance of making it back to Canada alive.

Advanced body armour, advanced trauma life support provided by medics on the battlefield and rapid evacuation of the wounded — all are factors behind the improved survival rates.

Still, more than 600 Canadian soldiers have been wounded in action in Afghanistan; more than 1,400 others have sustained non-battle injuries (such as injuries from traffic accidents or the accidental discharge of a weapon).

Many of these injuries will result in pain that is relentless, Lynch says. In addition, research in the U.S. shows that more than half of military personnel suffering physical pain from combat wounds are also plagued by depressionanxietypanic disorder and other psychological problems — a phenomenon experts have dubbed “post-deployment multi-symptoms disorder,” or PMD.

Blast-related injuries can dominate — wounds from IEDs and landmines and rocket-propelled grenades. The blast force can cause head-to-toe trauma, from “de-gloving injuries” — stripping of skin and soft tissue from bones — avulsion of limbs requiring amputation, shattered pelvic bones, genital amputation, bowel and bladder injuries, hand or finger amputation, punctured lungs and traumatic brain injury.

Soldiers can survive their wounds only to be left with complex regional pain syndrome — “nerve damage that causes pain that is excruciating,” says Lynch, past president of the Canadian Pain Society, co-host of next week’s pain summit. “Even the touch of a cotton ball can be painful, or the sound of a plane overhead or a newspaper rustling in the same room.”

Until Canada pulled out of its combat role in Afghanistan, Lt.-Col. Markus Besemann received casualty and wounded reports regularly.

“Amputees are certainly the most graphic ones,” said Besemann, head of the CF’s rehabilitation program. But other severe injuries involve “multiple orthopedic trauma” — broken bones, shattered pelvis — nerve damage, head trauma, spinal cord injuries and internal organ damage from blasts.

Most military hospitals in Canada were shuttered in the 1990s, their role handed to the civilian sector. Military personnel who need specialized care are treated at civilian hospitals and rehabilitation centres, with followup care provided by their base health clinics. But not all have multi-disciplinary pain programs.

The Canadian Forces has two chronic pain management programs — one in Halifax, the other in Ottawa — that teach patients breathing techniques, mindfulness meditation and other exercises to help manage their pain. The plan, Besemann said, is to expand them to major bases across the country.

Patients are sent to the teams after everything that can be done medically is done, he said.

In addition, doctors specializing in rehabilitation medicine are being hired for bases in Gagetown, Edmonton and Quebec City.

He said soldiers needing complex care could be fast-tracked to civilian pain clinics within a matter of months.

Lynch says the decision on who should take priority should be made on the basis of urgency of need, “and not whether a person is a civilian or in the military.”

“The whole system needs to be fixed,” she said. “There is massive ignorance about the appropriate treatment for chronic pain.”

Pain researchers, doctors and patient groups across Canada want a national pain strategy that would see more investment in training doctors — civilian and military — in pain and more specialized pain clinics.

But for soldiers, there are other challenges in seeking care: The “tough-it-out” mentality embedded within the military can make soldiers fearful that their careers will end if they report that they’re in pain.

“I guess it’s inbred in their training to suck it up,” Besemann says. “They often come back and tell me that: I was basically taught as an infanteer I have to just suck it up and get on with it.”

Many delay seeking care until their pain becomes chronic, he said.

“People are desperately wanting to maintain their careers, and so they’ll push through pain. . . . And those are significant challenges, trying to convince people, ‘Look, you need to come to us earlier, rather than later.’ ”

Pain isn’t a threat to a career, he said, “so long as the condition they have is treatable.”

Yet a recent Postmedia News series on Canada’s combat mission in Afghanistan told how the number of soldiers being “medically released” jumped from a low of about 675 a year in 2002 to almost 1,200 a year in 2006.

Many of these were forced out, their injuries from Afghanistan leaving them unable to fulfil the military’s requirement that all personnel be physically able to go into combat. Then-chief of defence staff Rick Hillier would later promise to exempt any soldier wounded in Afghanistan from that requirement — a promise some have complained is inconsistently applied.

Campbell, of Edmonton, says for serving soldiers with pain, “the career is on the line, and every soldier knows it.” For those with back pain, knee pain, shoulder pain: “You walk it off, you suck it up, and you do what you’ve got to do.”

The difference for him is that, “I’m done.”

“I’m never going to be an infantry officer again. I’m finished. My career is over,” he says. “What’s holding me back from saying: ‘Hell, I hurt. I want it fixed.’ ”

It took two tourniquets on each leg to stop his severed femoral arteries from bleeding him out. He was lucid — and in “indescribable agony” — the entire time it took soldiers to run with him on a carpet stretcher, through irrigation ditches and with gunshots and grenades exploding around them, to a secure area where an evacuation helicopter could safely land.

Campbell spent two months at Edmonton’s Glenrose Rehabilitation Hospital — a rehab centre that a 2008 Senate committee report on national security and defence said stands out in Canada “like a 2009 Lamborghini on a car lot dotted with too many 1970 Ladas.”

After Campbell was discharged home, the phantom pain was so severe he couldn’t sleep most nights. His military psychiatrist referred him to a University of Alberta Hospital specialized pain clinic, where his doctor suggested methadone.

“Campbell remembers thinking: “The pain is so bad that I need a heroin treatment for it?”

The drug, he says, has been a “life changer.”

It allows him to sleep; it helps keep him from thinking about the pain.

For Campbell, the road to rehabilitation has been long. “You don’t ever fully recover from wounds like mine,” he says.

His pain, he says, is exacerbated by the struggle for fair compensation from the government of Canada.

“One moment you’re in combat, then the next thing you know you’re in a hospital bed, and you’ve got no legs,” he said. “The last thing you remember was that whole horrible incident you hope was just a nightmare.

“Except once the drugs wear off, you realize, ‘this isn’t a nightmare. This is real.’

“And the nightmare never really lets up.”

Neuroscientist’s book gives tips, exercises for training your brain to boost emotional connections

By HEIDI STEVENS, McClatchy News, June 18, 2012

“Life’s slings and arrows” is Harvard-educated neuroscientist Richard J. Davidson’s phrase for the events we spend our days ducking, sometimes unsuccessfully.

Losing out on that promotion. Getting dumped. Navigating a cocktail party of boors (or bores). The stuff that conspires to keep us in a foul mood, despite our best intentions.

And Davidson argues that our response to such events — and even to full-on tragedies, such as the death of a loved one — is as much a part of our identity as our fingerprints.

“Each of us is a colour-wheel combination of the resilience, outlook, social intuition, self-awareness, context and attention dimensions of emotional style,” he writes in his book, The Emotional Life of Your Brain, “a unique blend that describes how you perceive the world and react to it, how you engage with others and how you navigate the obstacle course of life.”

Unlike our fingerprints, though, our emotional style can be altered. “We have the power,” Davidson contends, “to live our lives and train our brains in ways that will shift where we fall on each of the six dimensions of emotional style.”

That may sound more like your yoga instructor than a guy who has spent the past three decades studying brain chemistry. But study brain chemistry he does, which makes his findings all the more compelling. (And he did spend three months during graduate school in India and Sri Lanka studying meditation, therefore he’s entitled to sound a little like a yogi.)

So, the six dimensions. Davidson, a professor of psychology and psychiatry at the University of Wisconsin-Madison, identifies them as such, based on activity he has identified in specific brain circuits:

Resilience: How slowly or quickly you recover from adversity.

Outlook: How long you are able to sustain positive emotion.

Social intuition: How adept you are at picking up social signals from the people around you.

Self-awareness: How well you perceive bodily feelings that reflect emotions.

Sensitivity to context: How good you are at regulating your emotional responses to take into account the social context you find yourself in.

Attention: How sharp and clear your focus is.

The book offers exercises to help assess your emotional style, mostly from true-or-false statements. (“When I go to a museum or attend a concert, the first few minutes are really enjoyable, but it doesn’t last.” “Often, when someone asks me why I am so angry or sad, I respond or think to myself, ‘But I’m not!’ ”)

Answers yield a score that places you on a spectrum for each of the six dimensions. Scoring 1 in resilience, for example, means “fast to recover”; a 10 indicates “slow to recover.”

“There’s no single optimal emotional style,” Davidson said. “Emotional diversity is crucial for the successful operation of society. It’s good, for example, that we have people who prefer to interact with machines over people.

“Neither end of the spectrum is necessarily better or worse than its opposite.”

Still, he contends, certain emotional styles make it harder to lead a meaningful, productive life. Which inspires both the bad news and the good news from the book. A person who is self-opaque in the self-awareness department, puzzled in the social intuition department and unfocused in the attention department will likely struggle at dinner parties. (Bad news.) But Davidson’s findings say the brain is malleable enough to kick your scores up or down each spectrum a few notches, paving the way for future social success. (Good news!)

“It’s best to regard your emotional well-being as a skill that can be trained,” he says. “In many ways, it’s no different than learning to play the violin. If you practice, you’ll get better.”

Essentially, Davidson argues, our brains — and therefore, our personalities — are hybrids of our genes and our environment.

“We can’t do anything about our genes per se,” he says. “We’re all born with a complement of DNA that’s just not possible to change. But our brains are constantly being shaped by the forces around us, and we can take more responsibility for the optimal shaping of our brains by engaging in certain, deliberate behaviours.”

The extent to which certain genes are expressed, he notes, is largely affected by our environment — whether it’s stressful or safe, perilous or nurturing.

“The decades-old neuroscience dogma that the adult brain is essentially fixed in form and function is wrong,” he writes.

The final chapter is devoted to specific exercises for adjusting your emotional style — rewiring your brain, if you will.

To change your outlook: Write down one positive characteristic of yourself and one of someone you regularly interact with. Do this three times a day.

For social intuition: To enhance your sensitivity to vocal cues of emotion, when you are in a public place such as a subway, a busy coffee shop, a store or an airport terminal, close your eyes and pay attention to the voices around you. Tune into specific voices; focus not on the intent but on the tone of voice. Describe to yourself what that tone conveys: serenity, joy, anxiety, stress, etc.

“One of the central messages of the book is that different things work differently for different people,” he says. “I encourage people to try things, to have an inquisitive curiosity and a playful attitude to see what works.”

Different strokes for different folks, emotional diversity, we get all that. But we have to know: Is there one person who embodies a truly enviable emotional style?

“The Dalai Lama,” Davidson replies, without skipping a beat. “He is someone who I believe has extraordinary resilience, who recovers very quickly from adversity. He has a very positive outlook, in that he is able to maintain very high levels of positive emotion across time. He has extraordinary social intuition — he’s able to pick up on non-verbal cues of others in uncanny ways.

“Self-awareness: He is intimately in tune with what’s going on inside himself. He has tremendous awareness of context so that he can behave in ways that are appropriate to any given context. He has an enormous capacity to control his attention. On every one of the six emotional styles, he is an extreme end point.”

And he’s probably delightful at cocktail parties.

Sleeplessness eroding public health, say docs

By Charlie Fidelman, Postmedia News May 4, 2012

MONTREAL — Emergency room doctors helped implement seatbelt use, lung specialists led the charge to reduce cigarette smoking. Now, a group of sleep specialists meeting in Montreal is agitating for a sleep policy.

That’s right. A good night sleep is so important for physical and mental well-being that its lack poses a grave risk to public health, experts say.

If science has yet to unravel the mystery of why we need to sleep, the toll of inadequate slumber is well-documented in studies linking bad sleep to obesitycancercardiovascular diseases and metabolic disorders. Lack of sleep weakens the immune system.

Look at the numbers: 25 per cent of adults don’t get enough sleep or have chronic insomnia, said psychologist Reut Gruber, director of the attention, behaviour and sleep lab at the Douglas Mental Health University Institute in Montreal.

But the worst group for sleeplessness is adolescents: up to 80 per cent of Canadian students come to school extremely sleep-deprived, while the portrait of school age children “isn’t pretty . . . 43 per cent are going to bed at a very, very late time.”

Robust evidence on sleep deprivation and health consequences led most medical schools in North America, including Montreal’s McGill University, to abolish 24-hour shifts for medical residents. Not only do sleepless nights impede students’ ability to learn, they can lead to medical errors that put patients at risk.

Fatigue is cumulative, and crashing on weekends to play catch-up doesn’t work, said Gruber, who is bringing together about 40 sleep scientists from across Canada and the United States to discuss how to translate sleep medicine research, specifically pediatric sleep, into educational and public policies and lifestyle changes.

Some people suffer from sleep apnea or other medical problems that interfere with slumber, but for many, the chief culprit is the mistaken belief that sleep is a waste of time.

“Sleep feels like it’s something we can give up when we have other competing priorities,” said Gruber, who is chair of the pediatric interest group, Canadian Sleep Society. “Our choices are going to affect many things that are important to us.”

In fact, sleep should be a high health priority, along with eating well and exercising, she said.

Children, for example, need at least nine hours of sleep, Gruber said. Among other functions, sleep allows the brain to do its “executive actions”, consolidating learning and memory, something that is imperative for academic performance, she said.

Working guidelines on good sleep hygiene would mean, for example, that sports and cultural activities would not be scheduled late on school nights

“I’m very excited to hear presentations from the (Quebec) institute of public health on this topic. It’s a great step forward,” Gruber said. “My request to each presenter was to identify barriers to integrating pediatric sleep into public health and the education systems.

“We have the knowledge. We have the evidence. Why can’t we integrate it and overcome the barriers?”

Five common myths about sleep.

1. Sleep is a time when your body and brain shut down for rest and relaxation.

False. Our bodies and brains actually do a lot of work while we sleep, which helps us to refuel and to stay healthy and happy. Sleep also plays an important role in memory and learning; as we sleep, we consolidate all the information we learned during the day.

2.  Sleep is less important than some of our other important basic needs, such as eating.

False. Even cutting our sleep by one hour one night has a serious impact on our health, mood, and behaviour the following day. Furthermore, a single night of partial sleep deprivation is enough to impair our immune functioning, which heightens our risk for acquiring a virus or illness.

3.  Adolescents need less sleep than younger children.

False. While it is true that adolescents tend to get less sleep than younger children and may have a harder time falling asleep, getting an adequate amount of sleep is still just as important for their development and well-being as it is for younger people.

4.  Sleeping in on weekends compensates for lack of sleep throughout the week.

False. Having a consistent bedtime and wake time throughout the week is important to ensure we maintain healthy sleep habits. Waking up early throughout the week and then sleeping in on the weekends creates an irregular sleeping schedule and confuses our bodies. If we do not get enough sleep one night, a better way to compensate for this is a short nap in the afternoon.

5.  Alcohol and other sedatives help us to sleep.

False. While alcohol may help us to fall asleep easily and quickly, it actually disrupts our sleep and prevents us from achieving a deep, restful sleep. Sleeping pills can be problematic. If we use them regularly and then stop, it becomes difficult to fall asleep without their use, thus starting a vicious cycle of dependence.

Could poor mental health be driving Canada’s obesity epidemic?

By Sharon Kirkey, Postmedia News June 18, 2012

Canada is losing the war against obesity because we’re ignoring one of its major drivers, doctors say: the state of our mental well-being.

Some say obesity and mental health are so intricately entwined, they should be considered a “double epidemic.”

Depressionanxietysleep disordersattention deficit disorderspost traumatic stressaddictions — all can cause changes in appetite, energy and metabolism that can prime people to gain weight. What’s more, antidepressants, mood stabilizers and newer generation anti-psychotics — drugs Canadians are being prescribed in record numbers — can themselves cause rapid and dramatic weight gain.

No one is suggesting that everyone with a weight problem has a mental illness.

But missing in the relentless drumbeat to “eat less, move more” is any public discussion about the role common mental health problems are playing in the obesity dilemma, observors say.

“We absolutely have not looked at this issue at all,” says Dr. Valerie Taylor, chief psychiatrist at Toronto’s Women’s College Hospital.

“This is probably one of the number one reasons that we’re not getting anywhere in terms of battling the obesity epidemic.”

The relationship works both ways.

Fat tissue isn’t inert. It’s biologically active. It produces cortisol, a stress hormone, as well as inflammatory chemicals, both of which have been linked to mental illness. Cortisol is neuro-toxic. It can act on the brain in vulnerable people — putting them at increased risk for depression.

Conversely, people with depression produce excess cortisol. And one of the effects of cortisol on the body, Taylor and her colleagues recently reported in the Canadian Journal of Psychiatry, is a propensity to accumulate fat around the abdomen.

The interplay between obesity and mental health is complex, but “we have not had a public discourse on how tightly these two epidemics are linked,” says Dr. Arya Sharma, professor of medicine and chair in obesity research and management at the University of Alberta.

Nowhere in the recent report from Canada’s mental health commission is there a mention of obesity, he says. “And vice versa. With all the talk about healthy weights, there’s a lot of focus on diet and exercise, but I don’t see any focus on improving the mental health of our kids and our adults. And that is a huge part of what is really driving the obesity epidemic.”

Studies have found that 66 per cent of those seeking bariatric, or weight loss surgery have had a history of at least one mental health disorder. Attention deficit disorder occurs in an estimated one in four. “These people really struggle with being able to eat healthy — they make impulsive choices, they can never make it to the gym, or they get to the gym, they’ve forgotten half their stuff,” Taylor says. “If you get that illness under control they can be successful in losing weight.”

Currently, 62 per cent of the nation’s adult population is either overweight or obese, a trend that’s tracking at an even faster pace among children and adolescents. Today, there are more overweight than “normal” weight Canadians, and the heaviest weight classes are growing the fastest.

In many cases, the weight gain happens so insidiously, people can’t put their finger on exactly how it happened.

Humans have been hard-wired through evolution to eat as much, and as often, as we can, and the food industry, critics say, has done a formidable job creating extraordinarily seductive foods loaded in sugar and fat. Some of the world’s leading addiction researchers believe today’s highly processed foods interact with the brain in ways similar to cocaine or heroin.

It takes significant impulse control to resist the smorgasbord before us, “because your brain wants all of those things and can’t get enough,” says Sharma, who will be among the featured speakers at a three-day conference on obesity and mental health in Toronto later this month sponsored by the Canadian Obesity Network, the International Association for the Study of Obesity and the Centre for Addiction and Mental Health.

“Even the slightest problem with impulse control and decision-making is going to expose you, and make you much more likely to gain weight,” Sharma said.

“I can’t think of a single mental health problem which would not, in some form or fashion, contribute to weight gain, or make weight management extremely difficult for someone who has the genetics to put on weight.”

Mood affects metabolism and changes the way the body responds to certain foods, he said.

Depression or bipolar disorder can cause changes in appetite, energy and motivation. Depression and anxiety cause play havoc with sleep, and the link between sleep problems and weight has never been stronger.

In a normal, sleep-wake cycle, leptin — the satiety or “I’m full hormone” that tells the brain to reduce food intake — increases, while ghrelin, which triggers appetite, decreases. That’s so that people don’t feel hungry when they’re sleeping.

But when sleep is disrupted, the opposite occurs, Taylor’s team wrote, so that people are not only awake, but they’re also hungry.

Taylor says the links are also strong between adult obesity and abuse in childhood — emotional abuse, physical abuse and neglect. “Sexual abuse is probably the biggest one,” she says. “Often times children incorrectly blame themselves for causing the abuse, so they want to change the way they look.”

Psychiatric drugs — among the most commonly prescribed pills nationwide — are adding to the problem. Antipsychotics — medications that are now even being used for insomnia — can trigger “hedonic hyperphagia” — eating in pursuit of reward, rather than to ease hunger.

“With some drugs, they can put on massive amounts of weight,” says Rohan Ganguli, professor of psychiatry and Canada Research Chair at the University of Toronto. One of his patients gained more than 100 pounds over the course of a year.

The drugs are often necessary. “But we have to mitigate risk,” Taylor said. “We need to be aware of these side effects and prescribe correctly.”

Food soothes anxiety and stress. It becomes a coping mechanism. Certain foods like carbohydrates can boost serotonin, which affects mood. For brief periods of time, we feel relaxed and comforted. But it doesn’t last, and so people get into a cycle, Taylor says, “where they’re constantly using food to feel better.

“We have to teach people how to stop doing that.”

Taylor says she can’t think of a more stigmatized group than those who have both obesity and mental illness. “Lots of times people don’t come forward and say they have a psychiatric illness going on when they’re looking for obesity treatment. Family doctors don’t ask about it.

“We need to raise awareness. This is a complicated illness. It’s not a blame thing. There are associations and things occurring that people aren’t aware of,” Taylor says.

“You have to care about the whole person, and not just one symptom.”

New motorcycle helmet law rides into B.C.

By Ted Laturnus, June 14, 2012, The Georgia Straight

After almost 30 years, the B.C. beanie is history. As of June 1, there are new rules governing motorcycle helmets in British Columbia, and so-called novelty helmets—in particular, the B.C. beanie—are out.

Offering about as much protection to riders’ heads as a Tupperware bowl, the low-cost beanies managed to slip through the cracks in the late 1980s when—among other things—the existing helmet laws were challenged in court by various groups, one of which claimed that being obliged to wear a motorcycle helmet infringed on their right to wear religious headgear. Since then, law enforcement has essentially overlooked the beanie, despite common knowledge that it’s not legal and does almost nothing to prevent head trauma in the event of an accident.

The statistics are hard to argue with. According to the B.C. Ministry of Justice, helmet laws—and proper headgear—have been found to reduce accident fatalities by as much as 37 percent. Since motorcyclists are eight times more likely to be killed and some 40 percent more likely to be injured in a vehicle collision than other road users, wearing proper headgear is a bit of a no-brainer. If you ride regularly and wear a beanie or a skid lid, the only reason you haven’t been injured is sheer luck. Even a relatively low-speed collision can have dire consequences if all you have on your head is a one-centimetre-thick piece of fibreglass.

Unbelievably, some riders in B.C. have even found store-bought beanies to be too large, whittling down their “helmets” to skullcaps the size of a yarmulke. Other riders claim that a full-sized helmet with a front visor and proper padding limits their peripheral vision and deadens road noise so they can’t hear what’s going on around them. Interestingly, authorities in Italy also recently banned the use of inadequate helmets on scooters and motorcycles.

So what constitutes a proper helmet? First of all, it must meet industry standards established by the U.S. Department of Transport, which Canada adopted years ago, or those established by the Snell Memorial Foundation. This latter group is a nonprofit research foundation whose purpose is to define what constitutes proper head protection “through scientific and medical research, standards development, helmet testing and public education”. It was founded after the death of amateur racing driver Pete Snell in 1957, and is recognized by virtually every sanctioned motorsport body in North America, including the American Motorcyclist Association, the National Hot Rod Association, NASCAR, the Sports Car Club of America, and others.

Although several high-profile accidents have brought the helmet issue to the fore, law-enforcement personnel in B.C. have chafed over the beanie loophole for years. Says Jamie Graham, former Vancouver chief of police and chair of the B.C. Association of Chiefs of Police traffic safety committee, in a news release, “We have seen the harm that inadequate safety equipment and poor choices cause. You have to be responsible for your actions, dress appropriately, pay attention and focus on driving.”

What happens if you defy the law and ride around with a beanie now? The first fine is $138, and if you can’t produce a legal helmet, that’s another $276, thank you.

Some other motorcycle safety regulations were brought forward by the B.C. government at the same time the beanie law was introduced. As of June, passengers riding on the rear pillion have to be able to “place their feet on foot pegs or floorboards”. If you have kids who can’t reach the rear pegs, they can’t ride. Ontario has had this law on the books for the past couple of years, and it makes sense all around.

As well, the size of the font on motorcycle licence plates has been increased slightly—some 0.95 centimetres—to “improve visibility and enforcement for police”.

Perhaps the best news to come out of the B.C. government’s announcements is that it intends to move forward with a graduated licensing program for new riders that may include restrictions on power and bike size. The U.K. has had this kind of system in place for years, and Ontario also has a type of graduated licensing program that restricts where and when you can ride but says nothing about the size or power level of the bike.

Most of these new regulations are for the good, but it’ll be interesting to see if another legal challenge is mounted against the new helmet laws.
