Specific types of “mindfulness practices” including Zen meditation have research-proven benefits for patients with certain physical and mental health problems, according to a report in the July Journal of Psychiatric Practice. The journal is published by Lippincott Williams & Wilkins,a part of Wolters Kluwer Health.

“An extensive review of therapies that include meditation as a key component—referred to as mindfulness-based practices—shows convincing evidence that such interventions are effective in the treatment of psychiatric symptoms and pain, when used in combination with more conventional therapies,” according to Dr William R. Marchand of the George E. Wahlen Veterans Affairs Medical Center and the University of Utah in Salt Lake City.
Mindfulness Techniques Show Health Benefits

Dr Marchand reviewed published studies evaluating the health benefits of mindfulness-based practices. Mindfulness has been described as “the practice of learning to focus attention on moment-by-moment experience with an attitude of curiosity, openness, and acceptance.” Put another way,
“Practicing mindfulness is simply experiencing the present moment, without trying to change anything.”

The review focused on three techniques:

Zen meditation, a Buddhist spiritual practice that involves the practice of developing mindfulness by meditation, typically focusing on awareness of breathing patterns.

Mindfulness-based stress reduction (MBSR), a secular method of using Buddhist mindfulness, combining meditation with elements of yoga and education about stress and coping strategies.

Mindfulness-based cognitive therapy (MBCT), which combines MBSR with principles of cognitive therapy (for example, recognizing and disengaging from negative thoughts) to prevent relapse of depression.

Dr Marchand found evidence that MBSR and MBCT have “broad-spectrum” effects against depression and anxiety and can also decrease general psychological distress. Based on the evidence, MBCT can be “strongly recommended” as an addition to conventional treatments (adjunctive treatment) for unipolar depression. Both MBSR and MBCT were effective adjunctive treatments for anxiety.

Research data also supported the effectiveness of MBSR to help reduce stress and promote general psychological health in patients with various medical and/or psychiatric illnesses. On its own, MBSR was helpful in managing stress and promoting general psychological health in healthy people.

There was also evidence that Zen meditation and MBSR were useful adjunctive treatments for pain management.

How do these practices work to affect mental and physical health? Dr Marchand discusses recent research showing the impact of mindfulness practices on brain function and structure, which may in part account for their psychological benefits. “These mindfulness practices show considerable promise and the available evidence indicates their use is currently warranted in a variety of clinical situations,” he concludes.
The article includes some proposed evidence-based guidelines for incorporating mindfulness-based practices into health care. So far there’s little evidence on which patients are most likely to benefit, but Dr Marchand suggests that patient preferences and enthusiasm are a good guide. He comments, “The most important considerations may be desire to try a mindfulness-based practice and willingness to engage in the regular practice of seated meditation.”

A landmark study of police officers in Buffalo, N.Y., reveals increased incidence of chronic disease, finds suicides higher among those still working.

The daily psychological stresses that police officers experience in their work put them at significantly higher risk than the general population for a host of long-term physical and mental health effects. That’s the overall finding of a major scientific study of the Buffalo Police Department called Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) conducted over five years by a University at Buffalo researcher.

“This is one of the first police population-based studies to test the association between the stress of being a police officer and psychological and health outcomes,” says John Violanti, PhD, professor of social and preventive medicine in the UB School of Public Health and Health Professions, and principal investigator on the study, funded by the National Institutes of Health.

The research, which is in press this month in a special issue of the International Journal of Emergency Mental Health, reveals connections between the daily stressors of police work and obesity, suicide, sleeplessness and cancer, as well as general health disparities between police officers and the general population.

The study was prompted by the assumption that the danger, high demands and exposure to human misery and death that police officers experience on the job contribute to an increased risk of cardiovascular disease and other chronic health outcomes.

“We wanted to know, in addition to stress, what are other contributing factors that lead to cardiovascular disease in police?,” says Violanti, a former New York State trooper. [continue reading…]

Why Chronic Pain is All in Your Head

When people have similar injuries, why do some end up with chronic pain while others recover and are pain free? The first longitudinal brain imaging study to track participants with a new back injury has found the chronic pain is all in their heads –- quite literally.

A new Northwestern Medicine study shows for the first time that chronic pain develops the more two sections of the brain — related to emotional and motivational behavior — talk to each other. The more they communicate, the greater the chance a patient will develop chronic pain.

The finding provides a new direction for developing therapies to treat intractable pain, which affects 30 to 40 million adults in the United States.

Researchers were able to predict, with 85 percent accuracy at the beginning of the study, which participants would go on to develop chronic pain based on the level of interaction between the frontal cortex and the nucleus accumbens.

The study is published in the journal Nature Neuroscience.

“For the first time we can explain why people who may have the exact same initial pain either go on to recover or develop chronic pain,” said A. Vania Apakarian, senior author of the paper and professor of physiology at Northwestern University Feinberg School of Medicine.

“The injury by itself is not enough to explain the ongoing pain. It has to do with the injury combined with the state of the brain. This finding is the culmination of 10 years of our research.”

The more emotionally the brain reacts to the initial injury, the more likely the pain will persist after the injury has healed. “It may be that these sections of the brain are more excited to begin with in certain individuals, or there may be genetic and environmental influences that predispose these brain regions to interact at an excitable level,” Apkarian said.

The nucleus accumbens is an important center for teaching the rest of the brain how to evaluate and react to the outside world, Apkarian noted, and this brain region may use the pain signal to teach the rest of the brain to develop chronic pain.

“Now we hope to develop new therapies for treatment based on this finding,” Apkarian added.

Chronic pain participants in the study also lost gray matter density, which is likely linked to fewer synaptic connections or neuronal and glial shrinkage, Apkarian said. Brain synapses are essential for communication between neurons.

“Chronic pain is one of the most expensive health care conditions in the U. S. yet there still is not a scientifically validated therapy for this condition,” Apkarian said. Chronic pain costs an estimated $600 billion a year, according to a 2011 National Academy of Sciences report. Back pain is the most prevalent chronic pain condition.
