Largest Neuroscience Study of Mindfulness as a Treatment for Addiction Published in Science Advances

The largest neuroscience study to date of mindfulness as a treatment for addiction shows that Mindfulness-Oriented Recovery Enhancement (MORE) can decrease opioid misuse by changing the brain.

Mindfulness-Oriented Recovery Enhancement Amplified Frontal Midline Theta EEG Power During Meditation

The study, published in the top journal Science Advances, provides new insight into the neurobiological mechanisms by which mindfulness treats addiction. Study findings provide a promising, safe and accessible treatment option for the more than 9 million Americans misusing opioids. Eric Garland is the lead author on the paper and is a distinguished professor, and associate dean for research at the University of Utah College of Social Work. He also directs the University of Utah’s Center on Mindfulness and Integrative Health Intervention Development. 

Garland’s study builds on previous research measuring the positive effects of theta waves in the human brain. Researchers have found that individuals with low theta waves tend to experience a wandering mind, trouble concentrating or they ruminate on thoughts about themselves. Theta waves can best be viewed on electroencephalogram, or EEG scans of the frontal midline regions of their brains. Low theta waves result in a loss of self-control as the brain slips into its default mode of automatic habits. In contrast, when a person is focused, present and fully absorbed in a task, EEG scans will show increased frontal midline theta wave activity.

“With high theta activity, your mind becomes very quiet, you focus less on yourself and become so deeply absorbed in what you are doing that the boundary between yourself and the thing you are focusing on starts to fade away. You lose yourself in what you are doing,” said Garland.

Garland’s new study showed it is in this mindful, theta wave state that people begin to experience feelings of self-transcendence and bliss, and the brain changes in ways that actually reduce one’s addictive behaviors. 

ABOUT THE STUDY

Garland’s research team recruited 165 adults with long-term opioid use for study. Participants were randomly placed into either the control group that participated in supportive group psychotherapy, or the experimental group taught to incorporate Mindfulness-Oriented Recovery Enhancement (MORE) into their daily lives. Before and after the eight weeks of study treatment, all participants were brought into the research lab and had their brain waves measured with EEG while they were asked to try to practice mindfulness meditation. Participants were assessed for opioid misuse for nine months after the treatment ended.

MORE is an eight-week, mindfulness-based therapy created by Garland to treat addiction, pain and emotional distress by promoting self-awareness and self-regulation of automatic and addictive habits. In a large clinical trial recently published in JAMA Internal Medicine, MORE was shown to reduce opioid misuse by 45%, more than doubling the effect of standard therapy.

Study participants in the MORE group learned to practice mindfulness meditation by focusing their attention on their breath or body sensations for sustained periods of time, and to refocus their attention when their minds began to wander into obsessive thinking about drugs or life stressors. 

STUDY FINDINGS

Participants showed more than twice as much frontal midline theta brain activity following treatment with MORE, whereas those in supportive therapy showed no increase in theta. Participants in MORE who showed the biggest increases in theta waves reported more intense experiences of self-transcendence during meditation, including the sense of one’s ego fading away, a sense of oneness with the universe or feelings of blissful energy and love.

Mindfulness-Oriented Recovery Enhancement Significantly Increased Self-Transcendent Experiences
The Effect of MORE on Reducing Opioid Misuse was Mediated by Increased Frontal Midline Theta

MORE also led to significant decreases in opioid misuse through the nine-month follow-up. These reductions in opioid misuse were caused in part by the increases in frontal midline theta brain waves. Garland explained that by achieving “tastes of self-transcendence” through meditation, the mindfulness therapy boosted theta waves in the frontal lobes of the brain to help participants gain self-control over their addictive behaviors.  

“Mindfulness can create a pathway for us to transcend our limited sense of self,” said Garland. “Civilizations have known for thousands of years that self-transcendence, the experience of being connected to something greater than ourselves, has powerful therapeutic benefits.”

This, he explained, is a part of why some cultures engage in spiritual practices, practice deep meditation or use psychedelic substances like psilocybin mushrooms. Even in the popular 12-step addiction treatment program, the 11th step—seeking conscious contact with a higher power through prayer or meditation—taps into this same mechanism to promote recovery from addiction.

The state of transcendence can be like a blissful, natural high. Garland stated, “Rather than seeking a high from something outside of yourself like a drug, meditation can help you to find an even greater sense of pleasure, peace and fulfillment from within.”

Dr. Garland Designated the Most Prolific Author of Mindfulness Research in the World

In a recent bibliometric analysis of mindfulness research published over the past 55 years, I was found to be the most prolific author of mindfulness research in the world. While I’m truly honored and humbled by this achievement, the real meaning of this body of work goes beyond numbers and world records. My deepest aspiration is that the scientific discoveries I’ve made over the past 15 years will reduce suffering and advance human flourishing.

Healing Pain and the Opioid Crisis with Mindfulness-Oriented Recovery Enhancement

On May 4, I had the honor of giving an invited lecture for the National Center for Complementary and Integrative Health (NCCIH) of the National Institutes of Health, entitled “Healing the Opioid Crisis with Mindfulness-Oriented Recovery Enhancement: Clinical Efficacy and Neurophysiological Mechanisms.” The full video of this lecture can be found here. In this lecture, I described my decade-long research program focused on developing and testing MORE as a treatment for chronic pain, opioid misuse, and addiction, and reported results from the largest clinical trial of MORE to date.

Dr. Garland presents his research on Mindfulness-Oriented Recovery Enhancement to NIH Leadership

I began the talk discussing the destructive processes that unwittingly propel a person suffering from prolonged pain down the path toward an eventual loss of control over opioid use. I have been studying these risk mechanisms undergirding opioid misuse and OUD in people with chronic pain for more than a decade, and the discoveries I have made, along with great science from the field, informed the development of MORE. Then I described the Mindfulness-to-Meaning Theory, a key theoretical framework underlying MORE, as well as MORE’s treatment components, including mindfulness meditation, reappraisal, and savoring. Finally, I detailed MORE’s clinical outcomes and mechanisms of action across four randomized controlled trials involving nearly 500 patients. MORE works by strengthening self-control, reducing the brain’s reactivity to drug cues, increasing the brain’s response to natural, healthy rewards, enhancing meaning in life, and eliciting experiences of self-transcendence.

Following the lecture, I had a fascinating dialogue with the Director of NCCIH, Dr. Helene Langevin, and the Deputy Director of NCCIH, Dr. David Shurtleff about the emergence of self-transcendence in biological systems and its impact on health, and the use of mindfulness as a prevention and treatment strategy. This dialogue then opened up into a fantastic question and answer period. After the talk, I had the honor of discussing my research with multiple program directors and branch chiefs at NIH. If you didn’t have a chance to listen in, you can still watch the videocast here!

Mindful positive emotion regulation as a treatment for addiction: from hedonic pleasure to self-transcendent meaning

My new theory paper was just published online in Current Opinion in Behavioral Sciences. This paper outlines my recent ideas about how an addictions treatment approach based on mindfulness can enhance healthy pleasure, joy, and meaning in life. Most addictions treatments are focused on decreasing negative psychological experiences (e.g., stress, craving) and unhealthy behaviors. Few have focused on increasing positive psychological experiences as a core treatment approach. This oversight ignores fundamental discoveries from addiction neuroscience that demonstrate the plasticity of the brain reward circuitry underlying addiction. Therapies that use mindfulness techniques to savor natural rewarding objects and events, self-generate internal reward responses, and access self-transcendence may remediate the dysfunction in the reward system and thereby reduce addictive behavior.

The abstract is below:

Chronic drug use is theorized to induce cortico-striatal neuroplasticity, driving an allostatic process marked by increased sensitivity to drug-related cues and decreased sensitivity to natural rewards that results in anhedonia and a dearth of positive affect. As such, positive emotion regulation represents a key mechanistic target for addictions treatment. This paper provides a conceptual model detailing how mindfulness may synergize a range of positive affective mechanisms to reduce addictive behavior, from savoring the hedonic pleasure derived from natural rewards, to self-generating interoceptive reward responses, and ultimately to cultivating self-transcendent meaning. These therapeutic processes may restructure reward processing from overvaluation of drug-related rewards back to valuation of natural rewards, and hypothetically, ‘reset’ the default mode network dysfunction that undergirds addiction.

Dr. Garland Discusses MORE for Chronic Pain and Addiction, Mindfulness Neuroscience, and Self-Transcendence – Full Podcast

I was recently interviewed by renowned psychotherapist Lisa Dale Miller for her Groundless Ground Podcast about a range of topics. It was definitely my favorite interview I’ve had to date. Lisa and I had a really fun conversation ranging from the treatment of chronic pain and addiction with mindfulness, to the neuroscience of reward, to Buddhist philosophy, to self-transcendence, and finally, to the arcane Tantric notion that the dynamic Primordial Bliss of Consciousness lies at the heart of all experience.

Eric Garland Interviewed on Groundless Ground Podcast by Lisa Dale Miller

Using my research on Mindfulness-Oriented Recovery Enhancement (MORE) as a launchpad, Lisa and I delve into specific clinical issues around the use of meditation as a means of alleviating physical pain and drug craving, providing mindfulness instruction to people suffering trauma, and how to enhance the sense of meaning and joy in life through reappraisal and savoring. We dig deep into the science of restructuring reward processes in the brain as novel approach to addictions treatment. Finally, we give a brief history of the science of mindfulness and how it developed from a core of mechanistic cognitive psychology to begin to explore the outer edge of meditative states of consciousness – including the study of how people can transcend their limited sense of self and come to feel intimately interconnected with the world around them.

We let it all hang out! Come check it out! The podcast is also available on Spotify.

Cultivating Joy through Mindfulness: An Antidote to Opioid Misuse, the Disease of Despair

New research shows that a specific mind-body therapy, Mindfulness-Oriented Recovery Enhancement (MORE), increases the brain’s response to natural, healthy rewards while also decreasing the brain’s response to opioid-related cues.

Brain function during viewing of opioid- and natural reward-related images was assessed with EEG

The study, published today in the journal Science Advances, examined data from four experiments involving 135 adults who took opioids daily for chronic pain. The study participants were randomly assigned to two groups where they participated in eight weeks of MORE or eight weeks of a therapist-led support group. At the beginning and end of the study period, researchers collected electroencephalogram (EEG) data, which measures brain function through electrical activity at the scalp.

The results showed that over the course of the study, the brains of the study participants in the MORE group became significantly less reactive to cues related to their opioid medications, while also becoming significantly more responsive when participants used mindfulness to savor natural pleasure.

“Previous research shows that prolonged use of opioids makes our brains more sensitive to pain and less receptive to the joy one might normally experience from natural rewards, like spending time with loved ones or appreciating a beautiful sunset,” explained Eric Garland, associate dean for research at the University of Utah College of Social Work and lead author of the study. “This blunted ability to experience natural positive feelings leads people to take higher and higher doses of opioids just to feel okay, and ultimately propels a downward spiral of opioid dependence and misuse. Because of this downward spiral, scholars are increasingly referring to chronic pain and opioid misuse as ‘diseases of despair.’” 

“The results of this study show that MORE can actually reverse that devastating trajectory,” said Garland.

In addition to these objective EEG findings, participants in MORE also reported feeling enhanced joy and more meaning in life, results which Garland detailed in a paper published earlier this month in the Journal of Consulting and Clinical Psychology. They also reported experiencing significantly less pain and greater positive psychological health (positive emotions, the ability to savor natural pleasure and self-transcendence) than those in the support group. The study concluded that three months after treatment, MORE reduced risk of opioid misuse by increasing positive psychological health and decreasing pain. 

Garland developed MORE as an integrative mind-body therapy designed to promote positive psychological health while simultaneously addressing addiction, pain and stress. MORE teaches mental training techniques to help people to find meaning in the face of adversity while simultaneously alleviating physical and emotional pain by cultivating positive feelings and experiences.

“MORE teaches people to better notice, appreciate and amplify the good things in life, while also deriving meaning and value from difficult situations,” said Garland.

Taken together, Garland explains, these studies indicate that by changing brain function and promoting positive psychological health, MORE may increase happiness and an enhanced sense of meaningfulness in the face of adversity. These positive psychological effects, in turn, appear to reduce pain and prevent the misuse of opioids. Thus, enhancing joy and meaning in life through mindfulness may be an antidote to diseases of despair, Garland explains.

It is estimated that approximately 20-30 percent of U.S. adults experience chronic pain. Opioid painkillers are often prescribed to these patients, but a quarter of those who take these powerful drugs long-term end up misusing them. With opioids accounting for 63 percent of all drug overdose deaths in 2015, the widespread misuse of this class of drugs has been deemed a public health crisis. 

“Our nation’s opioid crisis kills more than 100 people a day,” said Garland. “So it is critical that we help develop new and effective ways to prevent opioid misuse. The data shows that MORE can play that key role.”

New Research Funding: Understanding the Neural Mechanisms of MORE as a Treatment for Smoking Cessation

Along with my colleagues Drs. Brett Froeliger and nidaMichael Saladin (Medical University of South Carolina), I was recently awarded a 5-year, $2.3 million grant from the National Institute on Drug Abuse to study the neural mechanisms of Mindfulness-Oriented Recovery Enhancement (MORE) as a smoking cessation intervention. In this study, 100 smokers will be randomly assigned to receive eight sessions of MORE or eight sessions of cognitive-behavioral therapy (CBT) to assist them in quitting smoking. Before and after the eight session intervention, participants will complete a task while their brain activity is being recorded in a fMRI scanner to measure their neural response natural rewards and cigarette cues. According to the allostatic model of addiction, as addiction progresses, the brain becomes hypersensitive to drug-related cues and triggers, and insensitive to natural, healthy rewards and pleasures, resulting in a lack of hedonic pleasure and dysphoria that pushes the individual to take higher and higher doses of the drug just to feel okay. This study is designed to test my restructuring reward hypothesis, which states that mindful savoring can reduce addictive behaviors by causing a shift in brain reward circuitry from valuing of drug-related rewards back to valuing natural rewards – reversing the allostatic process of addiction. This new research grant builds upon our earlier published proof-of-concept study showing that MORE increases savoring-related neural activation in the MORE-fMRI-SBmedial prefrontal cortex and ventral striatum – key reward-related brain areas. This increase in brain activity was associated with significant reductions in cigarette smoking. Here we will seek to replicate this finding using a rigorous, randomized clinical trial design. It is my sincere hope that this work will help to free people from smoking – the leading cause of preventable death in the United States.

Research on MORE Covered by NIDA: Prescription Opioid Misuse Treatment Leverages Mindfulness To Amplify Natural Rewards

nidaThe National Institute on Drug Abuse (NIDA) covered a recently published study of Mindfulness-Oriented Recovery Enhancement (MORE) on their NIDA Notes page. NIDA Notes has provided in-depth coverage of research findings on drug abuse and addiction for the past 25 years. Each month, 2-4 research articles from the entirety of addiction science are covered on NIDA’s webpage, so this is great recognition for the MORE research program.

We previously demonstrated that MORE can reduce chronic pain patients’ misuse of opioids (Garland et al., 2014, Journal of Consulting and Clinical Psychology). Now, a follow-up analysis of data from that study found these reductions in opioid misuse to be associated with an increase in patients’ cardiac-autonomic responsiveness to cues for natural rewards relative to cues for drug rewards (Garland et al., 2017, Psychotherapy and Psychosomatics). This is one of the most important discoveries I have made in the past decade, and suggests that MORE may reduce risk for opioid misuse by increasing physiological sensitivity to natural rewards. Thus, using mindfulness to amplify savoring of natural, healthy pleasures and promote meaning in life may be an antidote to opioid misuse, a condition that has been called a “disease of despair.”

Mindfulness-Based Treatment of Addiction: Current State of the Field and Envisioning the Next Wave of Research

I am pleased to announce that my colleague Matthew Howard and I had a new, invited manuscript accepted in the journal Addiction Science and Clinical Practice, an open access forum for clinically-relevant research that was previously published by the National Institute on Drug Abuse. The abstract for this paper (which is freely available to the public), entitled Mindfulness-Based Treatment of Addiction: Current State of the Field and Envisioning the Next Wave of Research is appended below:

“Contemporary advances in addiction neuroscience have paralleled increasing interest in the ancient mental training practice of mindfulness meditation as a potential therapy for addiction. In the past decade, mindfulness-based interventions (MBIs) have been studied as a treatment for an array addictive behaviors, including drinking, smoking, opioid misuse, and use of illicit substances like cocaine and heroin. This article reviews current research evaluating MBIs as a treatment for addiction, with a focus on findings pertaining to clinical outcomes and biobehavioral mechanisms. Studies indicate that MBIs reduce substance misuse and craving by modulating cognitive, affective, and psychophysiological processes integral to self-regulation and reward processing. This integrative review provides the basis for manifold recommendations regarding the next wave of research needed to firmly establish the efficacy of MBIs and elucidate the mechanistic pathways by which these therapies ameliorate addiction. Issues pertaining to MBI treatment optimization and sequencing, dissemination and implementation, dose–response relationships, and research rigor and reproducibility are discussed.”

First fMRI Pilot Study Published on the Effects of Mindfulness-Oriented Recovery Enhancement on Reward Processing in Addiction

IMORE-fMRI-SB‘m pleased to announce that the first fMRI brain imaging study of Mindfulness-Oriented Recovery Enhancement (MORE) has been published in the open-access journal Evidence-Based Complementary and Alternative Medicine (Froeliger et al., 2017). My colleague Brett Froeliger and I conducted this proof-of-concept pilot study at his TRAIN Lab at the Medical University of South Carolina to examine the effects of MORE on reward processes in the brains of people addicted to cigarettes. A sample of 13 smokers participated in a study testing MORE versus a comparison group. All participants underwent two fMRI scans 8 weeks apart. Between the first and second fMRI scan, participants in the MORE group learned mindfulness and reappraisal skills to decrease addictive reactions to cigarettes and savoring skills to increase responsiveness to natural rewards (e.g., social connection, natural beauty, healthy behaviors). Participants in the comparison group completed research measures but did not receive any treatment. Relative to the comparison group, MORE was associated with significant decreases in smoking (66% decrease) and significant increases in positive emotions. Crucially, MORE participants evidenced significant decreases in neural activity while viewing cigarette images in reward-related brain regions including the ventral striatum and ventromedial prefrontal cortex. MORE participants also demonstrated significant increases in neural activity in these same reward-related brain regions while they savored positive, natural-reward related images. Importantly, increases in brain activity during savoring were significantly correlated with smoking reduction and increased positive affect. These pilot findings provide preliminary evidence that MORE may facilitate the restructuring of reward processes and play a role in treating the pathophysiology of nicotine addiction. These findings converge with results from our other psychophysiological studies indicating that MORE may restructure reward processes in prescription opioid misuse (Garland, Froeliger, & Howard, 2014; Garland, Froeliger, & Howard, 2015; Garland, Howard, Zubieta, & Froeliger, 2017). Taken together, these data provide initial support for my restructuring reward hypothesis which asserts that mindfulness training may enhance a domain-general cognitive resource for restructuring reward learning from valuation of drug-related rewards to valuation of natural rewards and thereby reverse the downward spiral of addiction.

New R01 Grant from the National Institute on Drug Abuse: Targeting Chronic Pain and Prescription Opioid Misuse in Primary Care with Mindfulness-Oriented Recovery Enhancement

nidaRecently, I was awarded a R01 grant from the National Institute on Drug Abuse to conduct a full-scale clinical trial of Mindfulness-Oriented Recovery Enhancement (MORE) as an intervention to reduce chronic pain and prescription opioid misuse in primary care. This five-year study will compare the efficacy of MORE to supportive therapy for 260 chronic pain patients receiving long-term opioid therapy who are at risk for opioid misuse.

Opioids may be medically necessary for some individuals experiencing prolonged and intractable pain, and most patients take medicine as prescribed. Unfortunately, opioids rarely completely alleviate chronic pain, and when taken in high doses or for long periods of time, can lead to serious side effects, including death by overdose, as well as risk for opioid misuse, which affects about 1 in 4 opioid-treated patients. Misusing opioids by taking higher doses than prescribed or by taking opioids to self-medicate negative emotions can alter the brain’s capacity for hedonic regulation, making it difficult to cope with pain (e.g., causing hyperalgesia – an increased sensitivity of the nervous system to pain) and experience pleasure in life (e.g., reducing sensitivity of the brain to natural reward). As such, non-opioid pain treatments that target hedonic dysregulation may be especially helpful for reducing chronic pain and prevent opioid misuse.

Multiple studies suggest that MORE improves hedonic regulation in the brain, resulting in decreased pain and an increased ability to savor natural, healthy pleasure. People who participate in MORE show heightened brain and body responses to healthy pleasures, and report feeling more positive emotions by using of mindfulness as a tool to enhance savoring. These therapeutic effects of MORE on savoring may be critically important, because findings from several studies show that increasing sensitivity to natural reward through savoring may lead to decreased craving for drugs – a completely novel finding for the field of addiction science (Garland, 2016). Our NIDA-funded R01 will provide a rigorous test of whether MORE improves chronic pain and opioid misuse by targeting hedonic dysregulation.

In our NIDA-funded R01, patients are receiving MORE at community medical clinics throughout Salt Lake City. Providing MORE in the naturalistic setting where most chronic pain patients seek medical care will make the therapy accessible to the people who need it the most. Ultimately, my hope is that this project will advance a new form of integrative healthcare, in which doctors and nurses work alongside social workers and other behavioral health professionals to help patients reclaim a meaningful life from pain.

New Interview by Mind and Life Institute

mind_and-_lifeI was recently interviewed by Michael Juberg for the Mind and Life Institute, the world’s premier multi-disciplinary organization for the study of contemplative science. Michael and I had a wide ranging discussion that covered the span from philosophy to science to alleviating human suffering. He asked me some seriously thought-provoking questions that made me reflect back on the roots of my career and where it is all headed in the future. At the end of the interview, I offered a bit of advice for folks aspiring to become scientists in this field. The interview was really well done and I’m pleased to share it with you here.

New Research Funding: Neuroimaging Research on the Effects of Mindfulness-Oriented Recovery Enhancement on Hedonic Regulation

mindfulness-centered-regulation-in-brainChronic pain is often treated with extended use of opioid analgesics, yet these drugs can alter the brain in ways that may make it difficult to cope with pain and may reduce the experience pleasure in life. Mindfulness-based interventions appear to be a promising means of addressing these issues, but research is needed to understand how such interventions change the brain to reduce suffering.

To that end, in September, 2016, I was recently awarded a five-year phased innovation grant from the National Institutes of Health’s (NIH) National Center for Complementary and Integrative Health entitled Effects of Mindfulness-Oriented Intervention on Endogenous Opioid Mechanisms of Hedonic Regulation in Chronic Pain (R61AT009296). The objective of the project is to study the effects of an innovative mindfulness-based intervention on brain mechanisms linked with pain and pleasure.

In the first two-year phase of the study ($800,000), I (Principal Investigator), along with my Co-Principal Investigator Jon-Kar Zubieta (Co-Principal Investigator), chair of the University of Utah’s Department of Psychiatry, will use positron emission tomography (PET) neuroimaging to assess the effects of Mindfulness-Oriented Recovery Enhancement (MORE) on restoring brain levels of endorphins in patients with chronic back pain who are being treated with prescription opioids.

This study represents the first use of PET in the history of science to quantify the effects of a mindfulness-based therapy on levels of endogenous opioids in the brain.

We will also use functional magnetic resonance imaging (fMRI) methods to assess how mindfulness training through MORE may increase people’s capacity to savor natural pleasure from positive and meaningful events in everyday life – a capacity that becomes diminished over time through the deleterious effects of chronic pain and prolonged opioid use on the brain. We will use a fMRI paradigm developed by my Co-Investigator Brett Froeliger, Assistant Professor of Neuroscience at the Medical University of South Carolina.

This study aims to test whether MORE might reverse this insensitivity to natural reward by targeting the endogenous opioid system and brain reward functions.

Following a successful first phase of the project, a three-year second phase ($2.2 million) will investigate whether patients with a particular genetic makeup that affects the expression of opioid receptors in the brain might benefit more from the mindfulness-based treatment. The second phase of the project will also assess the dose of mindfulness skill practice as a predictor of changes in endogenous opioid function and clinical correlates.

Based on the results of previous research, we hypothesize that mindfulness meditation training through MORE will restore proper function to the brain’s opioid receptors.  We will be able to measure how MORE changes the brain’s ability to regulate pain and respond to natural rewards, as well as deepen our understanding of exactly how these changes in neural mechanisms happen.

more-conceptual-framework-opioid

Overall, this project will unite expertise in mindfulness-based interventions with expertise in neurogenetics and the use of PET and fMRI to probe the neurobiological mechanisms of pain and emotional experience. By elucidating a key mechanism of meditation-based therapies, this program of translational research will further the emerging field of social work neuroscience and enable us to rapidly optimize MORE to increase the effectiveness of the intervention as it is rolled out in clinical practice.
