Meditation Can Reduce the Age-Associated Degeneration of the Brain

“The brain begins to decline in the 20s, and continues to decrease in volume and weight through old age. Meditation, in addition to boosting emotional and physical well-being at any time in life, may be an effective way to prevent neurodegenerative diseases like dementia, Alzheimer’s and Parkinson’s, as well as help stave off some of the normal cognitive decline that comes with aging. The strategy is free, and it comes with no side effects.” – Carolyn Gregoire

Human life is one of constant change. We revel in our increases in physical and mental capacities during development, but regret their decreases during aging. The aging process involves a systematic progressive decline in every system in the body, the brain included. Starting in the 20s there is a progressive decrease in the volume and activity of the brain as the years go by.

The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. These changes in the brain are called neuroplasticity. Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread area. and have found that meditation practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits. In addition, they have been able to investigate various techniques that might slow the process of neurodegeneration that accompanies normal aging. They’ve found that mindfulness practices reduce the deterioration of the brain that occurs with aging restraining the loss of neural tissue. Indeed, the brains of practitioners of meditation and yoga have been found to degenerate less with aging than non-practitioners.

In today’s Research News article “Reduced age-associated brain changes in expert meditators: a multimodal neuroimaging pilot study.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5578985/, Chételat and colleagues recruited expert meditators with at least 10 years of experience and a total of at least 15,000 hours of meditation practice and age matched meditation naïve controls. They also included non-meditators at a wide range of ages, 20-87 years. They all underwent scanning of the brain with either Positron Emission Tomography (PET) or Magnetic Resonance Imaging (MRI). They were measured for verbal fluency, episodic memory, short-term memory, and working memory, processing speed and executive functions, frequency of participation in leisure activities before 30 and from 30 to 65 years, and the highest level of occupation reached, adherence to Mediterranean diet, sleep quality and sleep disturbance.

They found that the older the meditation naïve participants the lower the volume of the brain gray matter and the lower the brain metabolism. Hence, they demonstrated, as have many others, age related degeneration of the brain. On the other hand, the expert meditators had significantly greater brain gray matter volume and metabolic activity than the age matched controls in the bilateral ventromedial prefrontal and anterior cingulate cortex, insula, temporo-parietal junction, and posterior cingulate cortex /precuneus. All of the expert meditators were over 60 yet their brain volumes were in the range of meditation naïve controls in their 30s and 40s.

These are remarkable results that suggest that large amounts of meditation practice can help to preserve the brain countering age related decline. The amount of meditation performed by these expert meditators is so high as to be unrealistic for use with the general population. Fortunately, other research suggests that the elderly brain changes positively in response to much lower amounts of mindfulness practice. So, mindfulness training may well be a feasible practice to protect the brains of seniors from further deterioration.

So, use meditation to reduce the age-associated degeneration of the brain

“A growing body of research supports the immediate benefits of meditation, such as reduced stress and anxiety levels, lower blood pressure, and enhanced happiness. Studies on mindfulness interventions show these effects are common in as few as eight weeks. While these initial perks may be reason enough for us to practice, meditation’s positive impact appears to be even more far-reaching, potentially adding years to our lives and improving cognitive function well into old age.” – Rina Deshpande

Abstract

Aging is associated with progressive cerebral volume and glucose metabolism decreases. Conditions such as stress and sleep difficulties exacerbate these changes and are risk factors for Alzheimer’s disease. Meditation practice, aiming towards stress reduction and emotion regulation, can downregulate these adverse factors. In this pilot study, we explored the possibility that lifelong meditation practice might reduce age-related brain changes by comparing structural MRI and FDG-PET data in 6 elderly expert meditators versus 67 elderly controls. We found increased gray matter volume and/or FDG metabolism in elderly expert meditators compared to controls in the bilateral ventromedial prefrontal and anterior cingulate cortex, insula, temporo-parietal junction, and posterior cingulate cortex /precuneus. Most of these regions were also those exhibiting the strongest effects of age when assessed in a cohort of 186 controls aged 20 to 87 years. Moreover, complementary analyses showed that these changes were still observed when adjusting for lifestyle factors or using a smaller group of controls matched for education. Pending replication in a larger cohort of elderly expert meditators and longitudinal studies, these findings suggest that meditation practice could reduce age-associated structural and functional brain changes.

Protect the Aging Brain with Meditation

By John M. de Castro, Ph.D.

“long-term engagement in mindfulness meditation may enhance cognitive performance in older adults, and that with persistent practice, these benefits may be sustained. That’s great news for the millions of aging adults working to combat the negative effects of aging on the brain.” B. Grace Bullock

In today’s Research News article “Promising Links between Meditation and Reduced (Brain) Aging: An Attempt to Bridge Some Gaps between the Alleged Fountain of Youth and the Youth of the Field.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5447722/, Kurth and colleagues review and summarize the published research literature on the neuroprotective effects of meditation in the elderly. They discuss the ideas that the aging based deterioration of the brain is due to a number of processes, including changes in the DNA telomeres, inflammation, stress, and neuroplasticity and that meditation appears to effect all of these processes.

There has accumulated evidence that meditation protects against age related decline at the molecular genetic level. As we age the length of a DNA structures called the telomeres progressively shorten. It is thought that the shorter the telomeres get the more difficult it becomes for cells to replicate properly and thus leads to decline. Mindfulness training in general and meditation specifically, has been shown to reduce the shortening of the telomeres with aging. Kurth and colleagues speculate that this is one mechanism by which meditation protects the brain from age related decline.

As we age the natural inflammatory response that normally occurs to protect against infection begins to increase in general and lose its specificity to fighting particular diseases, pathogens, and injuries. It becomes more widespread damaging normal tissues. Mindfulness training in general and meditation specifically has been shown to reduce inflammatory responses. It seems reasonable that this is another mechanism by which meditation protects the body from age related decline.

Stress is present throughout life. But if it is too intense or prolonged the biological responses to stress begin to damage the body. These stress induced changes are similar to age related deterioration. Stress effects may accumulate over time. Hence, the older we get the greater the total stress induced damage. Mindfulness training in general and meditation specifically has been shown to improve emotion regulation and to reduce the physiological and psychological responses to stress. This is hypothesized to be another mechanism by which meditation protects the brain from deterioration with aging.

Neuroplasticity is a change in the size and connectivity of brain structures as they are exercised over a prolonged period of time. Mindfulness training in general and meditation specifically has been shown to produce neuroplastic changes in the brain, increasing the size and connectivity of brain structures. This process would tend to counteract brain degeneration with aging and may be another mechanism by which meditation protects the brain during aging.

Hence there has accumulated evidence that meditation reduces the deterioration of the brain with aging. It appears to do so by altering a number of different mechanisms including changes in the DNA telomeres, inflammation, stress, and neuroplasticity. This protection of the brain may be responsible to the ability of meditation to reduce the decline in mental abilities that occur with aging. This would tend to make aging a more benign process.

So, protect the aging brain with meditation.

We expected rather small and distinct effects located in some of the regions that had previously been associated with meditating. Instead, what we actually observed was a widespread effect of meditation that encompassed regions throughout the entire brain.” – Florian Kurth

Abstract

Over the last decade, an increasing number of studies has reported a positive impact of meditation on cerebral aging. However, the underlying mechanisms for these seemingly brain-protecting effects are not well-understood. This may be due to the fact, at least partly, that systematic empirical meditation research has emerged only recently as a field of scientific scrutiny. Thus, on the one hand, critical questions remain largely unanswered; and on the other hand, outcomes of existing research require better integration to build a more comprehensive and holistic picture. In this article, we first review theories and mechanisms pertaining to normal (brain) aging, specifically focusing on telomeres, inflammation, stress regulation, and macroscopic brain anatomy. Then, we summarize existing research integrating the developing evidence suggesting that meditation exerts positive effects on (brain) aging, while carefully discussing possible mechanisms through which these effects may be mediated.

Mindfulness Impairs the Formation of Automatic Habits

Mindfulness Impairs the Formation of Automatic Habits

By John M. de Castro, Ph.D.

“The very fact of paying too much attention or being too aware of stimuli coming up in these tests might actually inhibit implicit learning. That suggests that mindfulness may help prevent formation of automatic habits — which is done through implicit learning — because a mindful person is aware of what they are doing.” – Chelsea Stillman

When people think of learning they’re usually visualizing learning information like historical facts, people’s names, mathematical formulas, etc. This is called explicit memory. But, there’s another very important form of learning, called implicit learning, which is learning how to perform automatic tasks rapidly and efficiently. Things like riding a bike, playing a musical instrument, serving a tennis ball and tying your shoelaces all require implicit learning and memory.

Implicit learning requires the person to actually perform and practice a task to master it. Many athletic skills fall into this category. The skills are mastered with repetition so that they can be performed instinctively and mindlessly when needed. Implicit learning also involves most mundane tasks that we perform constantly throughout our day. Walking, producing speech, even typing this sentence on a keyboard all involve implicitly learned skills. So, implicit learning is important and helps to reduce the cognitive load on our nervous system for everyday behaviors. We don’t have the think about them so we can devote our brain capacity to higher level thoughts and ideas.

It has been demonstrated that mindfulness helps with explicit learning, such as academic material. For example, mindfulness training can improve college entrance exam scores in students. But, mindfulness appears to disrupt implicit learning. In today’s Research News article “Task-Related Functional Connectivity of the Caudate Mediates the Association Between Trait Mindfulness and Implicit Learning in Older Adults.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4955759/, Stillman and colleagues examine this disruptive effect of mindfulness and the neural systems responsible.

They recruited a group of healthy young adults (aged 18-37 years) and a group of healthy older adults (aged 60-90 years). They were measured for mindfulness and they completed an established implicit learning task. The task, Triplets Learning Task, involves a presentation of three stimuli with, unbeknownst to the participant, some triplets occurring more frequently than others. In general, people learn to respond to the more frequent triplets faster without awareness that there’s any difference between sets. In other words, they learn implicitly. While they were performing this task, their brains were scanned with functional Magnetic Resonance Imaging (f-MRI).

The researchers found that for the younger group, there was no significant relationship between mindfulness and implicit learning. On the other hand, the older group had a significant relationship between mindfulness and implicit learning with the higher the mindfulness score, the lower the score on the Triplets Learning Task. Hence, mindfulness disrupted implicit learning in older but not younger participants.

Investigating the brain scans of this older group, they found that the degree of relationship between mindfulness and implicit learning was related to the level of connectivity between the Caudate Nucleus and the Medial Temporal Lobe, a system previously shown to be associated with implicit learning. In particular, the greater the connectivity the better the implicit learning, but the greater the mindfulness, the lower the connectivity. A further mediational analysis indicated that the negative influence of mindfulness on implicit learning was mediated by its negative effect on the connectivity. In other words, mindfulness changed the brain which resulted in disruption of implicit learning.

These are complicated findings. But, they are particularly interesting as they suggest that mindfulness effects the brain and this produces the behavioral effects. The results suggest that the disruptive influence of mindfulness on implicit learning occurs primarily in older adults and that it is mediated by mindfulness’ negative influence on the functional connectivity of the Caudate Nucleus with the Medial Temporal Lobe. It is known that there is deterioration in the Caudate Nucleus and the Medial Temporal Lobe with aging. It is possible, then, that mindfulness can only exert its disruptive effects when there is an already weakened Caudate Nucleus – Medial Temporal Lobe system present.

It is interesting that mindfulness did not disrupt implicit learning in the younger participants. This might explain why mindfulness training improves athletic performance. Athletes are generally young and the lack of disruption of implicit learning by mindfulness allows mindfulness to produce psychological enhancements that improve performance. This might not be true for older athletes.

Regardless, it is clear that mindfulness disrupts the establishment of automatic unconscious habits in older adults as a result of its negative effects on the interaction of two brain areas, Caudate Nucleus and the Medial Temporal Lobe.

“people reporting low on the mindfulness scale tended to learn more—their reaction times were quicker in targeting events that occurred more often within a context of preceding events than those that occurred less often.” – Georgetown University Medical Center

Cognitive, Affective & Behavioral Neuroscience, 16(4), 736–753. http://doi.org/10.3758/s13415-016-0427-2

Abstract

Accumulating evidence shows a positive relationship between mindfulness and explicit cognitive functioning, i.e., that which occurs with conscious intent and awareness. However, recent evidence suggests that there may be a negative relationship between mindfulness and implicit types of learning, or those that occur without conscious awareness or intent. Here we examined the neural mechanisms underlying the recently reported negative relationship between dispositional mindfulness and implicit probabilistic sequence learning in both younger and older adults. We tested the hypothesis that the relationship is mediated by communication, or functional connectivity, of brain regions once traditionally considered to be central to dissociable learning systems: the caudate, medial temporal lobe (MTL), and prefrontal cortex (PFC). We first replicated the negative relationship between mindfulness and implicit learning in a sample of healthy older adults (60–90 years old) who completed three event-related runs of an implicit sequence learning task. Then, using a seed-based connectivity approach, we identified task-related connectivity associated with individual differences in both learning and mindfulness. The main finding was that caudate-MTL connectivity (bilaterally) was positively correlated with learning and negatively correlated with mindfulness. Further, the strength of task-related connectivity between these regions mediated the negative relationship between mindfulness and learning. This pattern of results was limited to the older adults. Thus, at least in healthy older adults, the functional communication between two interactive learning-relevant systems can account for the relationship between mindfulness and implicit probabilistic sequence learning.

Reduce Pain with Mindfulness

Reduce Pain with Mindfulness

By John M. de Castro, Ph.D.

“Mindfulness is an effective practice for approaching chronic pain. It teaches individuals to observe their pain, and be curious about it. And, while counterintuitive, it’s this very act of paying attention that can help your pain.” – Margarita Tartakovsky

We all have to deal with pain. It’s inevitable, but hopefully it’s mild and short lived. For a wide swath of humanity, however, pain is a constant in their lives. At least 100 million adult Americans and 1.5 billion people worldwide, have common chronic pain conditions. It is important to remember that pain is an important signal that there is something wrong or that damage is occurring. This signals that some form of action is needed to mitigate the damage. This is an important signal that is ignored at the individual’s peril. So, in dealing with pain, it’s pain signals should not be completely blocked or prevented. They need to be perceived. But, methods are needed to mitigate the pain and the psychological distress produced.

The most common treatment for chronic pain is drugs. These include over-the-counter analgesics and opioids. But opioids are dangerous and prescription opioid overdoses kill more than 14,000 people annually. The situation in the U.S. with opioid overdoses has become so severe that it’s taken on epidemic proportions. So, there is a great need to find safe and effective ways to lower the psychological distress and improve the patient’s ability to cope with the pain. Pain involves both physical and psychological issues. The stress, fear, and anxiety produced by pain tends to elicit responses that actually amplify the pain. So, reducing perceived stress and the emotional reactions to pain may be helpful in pain management. Indeed, mindfulness practices have been shown to reduce the physiological and psychological responses to stress and to improve emotion regulation producing more adaptive and less maladaptive responses to emotions. As a result, mindfulness practices have been shown to be effective in treating pain.

In today’s Research News article “Mindfulness meditation–based pain relief: a mechanistic account.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4941786/, Zeidan and Vago review the published research literature on the effectiveness of mindfulness practices in the treatment of pain. They report that the scientific research finds that mindfulness practices are safe and effective in treating perceived pain from a wide variety of conditions, including fibromyalgia, migraine, chronic pelvic pain, irritable bowel syndrome, and chronic low back pain.

Further, they report that the reduction in perceived pain appears to result from alterations of the nervous system. In particular, long-term meditators have significant increased activation of sensory processing–related brain regions (thalamus, insula) and reduced activation in brain areas that process the evaluation of pain (Medial Prefrontal Cortex), Orbital Frontal Cortex). There was also a significant relationship between meditative experience, lower perceived pain, and greater deactivation of the Medial Prefrontal Cortex / Orbital Frontal Cortex. Even after only brief meditation practice changes can be detected in brain areas that process pain stimuli (insula and anterior cingulate cortex) and the psychological appreciation of pain (Orbital Frontal Cortex).

These findings strongly suggest that in response to mindfulness practices multiple areas of the brain change, resulting in reduced subjective pain. These benefits can be obtained by short-term mindfulness practice but are further improved with long-term practice. Hence, mindfulness practices appear to be safe and effective alternative treatments to drugs and thereby may be useful in addressing the opioid epidemic.

So, reduce pain with mindfulness.

“When it comes to chronic pain, the key is learning to live with it rather than vainly trying to avoid or eradicate it . . . Mindfulness practice is a wonderful opportunity to do just that. It helps to shift the locus of control from the outside (“this is happening to me and there is nothing I can do about it”) to the inside (“this is happening to me but I can choose how I relate to it”).” -Christiane Wolf

Abstract

Pain is a multidimensional experience that involves sensory, cognitive, and affective factors. The constellation of interactions between these factors renders the treatment of chronic pain challenging and financially burdensome. Further, the widespread use of opioids to treat chronic pain has led to an opioid epidemic characterized by exponential growth in opioid misuse and addiction. The staggering statistics related to opioid use highlight the importance of developing, testing, and validating fast-acting nonpharmacological approaches to treat pain. Mindfulness meditation is a technique that has been found to significantly reduce pain in experimental and clinical settings. The present review delineates findings from recent studies demonstrating that mindfulness meditation significantly attenuates pain through multiple, unique mechanisms—an important consideration for the millions of chronic pain patients seeking narcotic-free, self-facilitated pain therapy.

Change the Brain with Mindfulness

Change the Brain with Mindfulness

By John M. de Castro, Ph.D.

“The picture we have is that mindfulness practice increases one’s ability to recruit higher order, pre-frontal cortex regions in order to down-regulate lower-order brain activity. In other words, our more primal responses to stress seem to be superseded by more thoughtful ones.” – Tom Ireland

There has accumulated a large amount of research demonstrating that meditation has significant benefits for psychological, physical, and spiritual wellbeing. Its positive effects are so widespread that it is difficult to find any other treatment of any kind with such broad beneficial effects on everything from mood and happiness to severe mental and physical illnesses. This raises the question of how meditation could do this. One possibility is that mindfulness practice results in beneficial changes in the nervous system.

The results of the research concerning the changes in the brain that occur with mindfulness practice have not presented a consistent picture. One issue may be the way that mindfulness is measured. This issue was explored in today’s Research News article “A distinction between two instruments measuring dispositional mindfulness and the correlations between those measurements and the neuroanatomical structure.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5524689/, Zhuang and colleagues compared Magnetic Resonance Images (MRIs), depression, and emotion regulation, between college students who had been measured for mindfulness with Mindful Attention Awareness Scale (MAAS) to those measured with the Five Factor Mindfulness Questionnaire (FFMQ).

They found that higher MAAS scores and FFMQ Describing, Acting with Awareness, and Non-judging scores the lower levels of depression. In addition, higher FFMQ Describing scores were significantly associated with higher emotion regulation. In regard to the brain scans they found that the higher the MAAS score the greater the size of the Precuneus area of the cortex. Mediation analysis demonstrated that the higher the volume of the precuneus cortical region the higher the MAAS score which in turn was associated with lower depression. So, mindfulness as measured by the MAAS was associated greater volume of the precuneus and was responsible for the relationship of the Precuneus volume with depression.

In regard to mindfulness measured with the FFMQ and the brain scans they found that the larger the size of the Superior Prefrontal Cortex, the higher the Describing and Non-judging facets and the lower the Non-reacting facet. In addition, the larger the size of the dorsolateral prefrontal cortex and the inferior parietal cortex the higher the Describing FFMQ facet. Mediation analysis demonstrated that the higher the volume of the Superior Prefrontal Cortex the higher the Describing FFMQ facet which in turn predicted higher emotion regulation. So, mindfulness as measured with the Describing FFMQ facet was associated greater size of the Superior Prefrontal Cortex and was responsible for the relationship of the Superior Prefrontal Cortex size with emotion regulation.

These results are interesting and suggest that the kind of relationship observed between changes in the brain and mindfulness is affected by the way mindfulness is measured. This could account for some of the conflicting findings in the published research. Also, since the Precuneus is associated with awareness of self, the results suggest that mindfulness as measured by the MAAS mainly measures self-awareness while since the inferior parietal cortex is also associated with awareness of self, the results suggest that mindfulness as measured by the Describing FFMQ facet also measures self-awareness. But the FFMQ mindfulness measure goes further and also documents other abilities. Since, the Prefrontal cortex is associated with attention control and emotion regulation, the results suggest that mindfulness as measured by the Describing and Non-reacting FFMQ facets also measure attention control and emotion regulation.

Clearly, mindfulness is associated with different sizes of areas in the brain’s cortical regions. But, even though the brain is different with mindfulness, the types of differences observed depends upon how mindfulness is measured. The Five Factor Mindfulness Questionnaire (FFMQ) measure appears to be superior to the Mindful Attention Awareness Scale (MAAS) as it breaks mindfulness down into component parts providing greater refinement in observed brain changes. These results will be helpful in future research unravelling the relationship of mindfulness to the characteristics of the nervous system.

“The practice of mindfulness can train our brains to have a new default. Instead of automatically falling into the stream of past or future rumination that ignites the depression loop, mindfulness draws our attention to the present moment. As we practice mindfulness, we actually start wiring neurons that balance the brain in a way that is naturally an antidepressant. “ – Debbie Hampton

Scientific Reports, 7, 6252. http://doi.org/10.1038/s41598-017-06599-w

Abstract

The most widely used measurements of mindfulness are the Mindful Attention Awareness Scale (MAAS) and the Five Facet Mindfulness Questionnaire (FFMQ). However, controversies exist regarding the application of these scales. Additionally, the neural mechanisms of dispositional mindfulness have become a topic of interest. In the current study, we used surface-based methodology to identify the brain regions underlying individual differences in dispositional mindfulness in a large non-clinical sample and compared the two instruments for measuring the dispositional mindfulness. The results indicated that the MAAS scores were significantly associated with increased grey matter volumes in the right precuneus and the significant association between the precuneus and depression symptomatology was mediated by MAAS scores. Regarding the FFMQ, the Describing, Nonjudging, and Nonreactivity facets were selectively associated with the cortical volume, thickness and surface area of multiple prefrontal regions as well as the inferior parietal lobule. Importantly, Describing mediated the association between the dorsolateral PFC volume and the cognitive reappraisal strategies of emotion regulation. These results suggested that the MAAS were mainly associated with self-awareness, while the FFMQ facets were selectively involved in emotion regulation, attention control and self-awareness. Therefore, this study characterized the differences in inter-individual variability between the two typical measurements of dispositional mindfulness and the correlations between those measurements and imaging analyses.

Alter Brain Networks and Cognitive Ability with Tai Chi

Alter Brain Networks and Cognitive Ability with Tai Chi

By John M. de Castro, Ph.D.

” Another great benefit of Tai Chi is that it’s accessible to people of all ages and fitness abilities. It’s the focus on the subtle movements that exercise the brain and boost cognitive abilities.” – Karl Romain

Tai Chi is an ancient Chinese practice involving mindfulness and gentle movements. It is easy to learn, safe, and gentle. Tai Chi has been practiced for thousands of years with benefits for health and longevity. Tai Chi training is designed to enhance function and regulate the activities of the body through controlled breathing, mindful concentration, and gentle movements. Only recently though have the effects of this practice been scrutinized with empirical research. This research has found that it is effective for an array of physical and psychological issues. It appears to strengthen the immune system, reduce inflammation and increase the number of cancer killing cells in the bloodstream, improve cardiovascular health, reduce arthritis pain, improve balance and reduce falls. It also appears to improve attentional ability and relieve depression.

In today’s Research News article “Mind-Body Practice Changes Fractional Amplitude of Low Frequency Fluctuations in Intrinsic Control Networks.” See summary below or view the full text of the study at: http://journal.frontiersin.org/article/10.3389/fpsyg.2017.01049/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_325025_69_Psycho_20170711_arts_A

Wei and colleagues recruited healthy long-term practitioners of Tai Chi (average 14 years of practice) and age, gender, and education matched non-practitioners. All participants performed a flanker task, a measure of executive cognitive function, in which the participant had to respond to the direction of an arrow surrounded by distracting arrows. They found that the longer the practitioners had been practicing Tai Chi the faster they responded in the flanker, executive function, task. This suggests that Tai Chi practice enhances cognitive function.

The participants then underwent functional Magnetic Resonance Imaging (fMRI) brain scanning. The brain scans revealed that the Tai Chi practitioners had a significant reduction in amplitude of low frequency fluctuations in the brain areas called the Default Mode Network (DMN) which underlies mind wandering and self-referential thinking. There was also a significant reduction in amplitude of low frequency fluctuations in the brain areas called the frontoparietal network (FPN) and the dorsal prefrontal-angular network which are associated with cognitive control and executive function. These changes in the low frequency fluctuations suggest that Tai Chi practice produces changes in these networks increasing their functional connectivity.

These results are very interesting and suggest that Tai Chi practice can produce changes in the brain improving the connectivities within large-scale neural systems. At least in terms of the frontoparietal network (FPN) and the dorsal prefrontal-angular network these changes may underlie the ability of Tai Chi practice to improve cognitive control and executive function while the changes in the Default Mode Network (DMN) may underlie the ability of Tai Chi practice to reduce mind wandering and self-referential thinking. Hence, Tai Chi practice alters the nervious system and produces very beneficial effects

So, alter brain networks and cognitive ability with Tai Chi.

“Neuroplasticity may sound like an out of this world term to a normal Tai Chi practitioner but to those who pursue the path of the mind, Warriors of Intention, then this is the proven way of enabling our mind to permanently rewire the way we move.” – Mushin

Abstract

Cognitive control impairment is a typical symptom largely reported in populations with neurological disorders. Previous studies have provided evidence about the changes in cognitive control induced by mind-body training. However, the neural correlates underlying the effect of extensive mind-body practice on cognitive control remain largely unknown. Using resting-state functional magnetic resonance imaging, we characterized dynamic fluctuations in large-scale intrinsic connectivity networks associated with mind-body practice, and examined their differences between healthy controls and Tai Chi Chuan (TCC) practitioners. Compared with a control group, the TCC group revealed significantly decreased fractional Amplitude of Low Frequency Fluctuations (fALFF) in the bilateral frontoparietal network, default mode network and dorsal prefrontal-angular gyri network. Furthermore, we detected a significant association between mind-body practice experience and fALFF in the default mode network, as well as an association between cognitive control performance and fALFF of the frontoparietal network. This provides the first evidence of large-scale functional connectivity in brain networks associated with mind-body practice, shedding light on the neural network changes that accompany intensive mind-body training. It also highlights the functionally plastic role of the frontoparietal network in the context of the “immune system” of mental health recently developed in relation to flexible hub theory.

Do Spiritual Experiences Reveal Ultimate Truth or Merely Brain Activity?

Do Spiritual Experiences Reveal Ultimate Truth or Merely Brain Activity?

By John M. de Castro, Ph.D.

Spiritual experiences, be they called awakenings, mystical experiences, or enlightenments, involve a shift in how the individual perceives reality. This could be viewed as a spiritual revelation. But it could also be viewed as a change in the neural systems integrating and interpreting experiences. So, are spiritual awakenings revelations of a reality beyond physical reality or are they simply hallucinatory experience evoked by changes in the nervous system?

One way of investigating this question is to study the brain-spirituality connection. Research along these lines has revealed that there is a clear association between spirituality and the brain. Modern neuroscience has developed methods, such as neuroimaging, to investigate the relationship. Applying these techniques it has been demonstrated that spirituality is associated with changes in the size, activity, and connectivity of the frontal and parietal lobes of the brain (see http://contemplative-studies.org/wp/index.php/2015/07/19/spirituality-mindfulness-and-the-brain/). So spirituality and changes in neural systems co-occur. But, this does not demonstrate a causal connection, whether spirituality alters the brain or brain alteration causes spirituality, or some third factor is responsible for both.

A better way to demonstrate if brain activity cause spiritual experiences is to investigate what happens to spirituality when the brain changes. One place to look at this is with accidental brain injuries incurred by humans that afford an opportunity to glimpses associations between brain change and spirituality. In general people who have incurred damage to the right inferior parietal area show an increase in spirituality. So, brain alteration affects spirituality. But, increased spiritual beliefs and spiritual seeking is not the same thing as spiritual experiences. So, we cannot conclude that these changes in the brain are responsible for awakening experiences.

Another manipulation of the brain occurs with drugs. Indeed, various hallucinogenic drugs such as mescaline, LSD, psilocybin, etc. have been shown to produce experiences that are extremely similar to spiritual experiences. These drugs have been shown to alter the activity in specific neurochemical systems in the brain and when that happens, experiences that are very similar to spiritual awakenings are evoked. Many people who have used these drugs are altered spiritually but vast numbers of people find hallucinatory drugs as fun recreation but are not affected spiritually.

Spiritual seekers who have used psychedelic substances report that they experience something like but not the same as spiritual awakening experiences. The following quote from Alan Watts is illustrative.

“Psychedelic experience is only a glimpse of genuine mystical insight, but a glimpse which can be matured and deepened by the various ways of meditation in which drugs are no longer necessary or useful. If you get the message, hang up the phone. For psychedelic drugs are simply instruments, like microscopes, telescopes, and telephones. The biologist does not sit with eye permanently glued to the microscope, he goes away and works on what he has seen…”

Also a quote from Ralph Metzner

“While psychedelic use is all about altered states, Buddhism is all about altered traits, and one does not necessarily lead to the other.”

Hence, it appears that although there are great similarities between manipulation of brain chemistry with drugs and the experiences occurring with spiritual awakenings, they are in fact quite different.

So, what should we conclude regarding the clear relationship between the brain and spiritual experiences? It has been established that spirituality changes the brain and that changes in the brain are associated with spiritual experiences. Does this indicate that spirituality is nothing but a brain function? This would suggest that spirituality and spiritual experiences are nothing but physical events and don’t represent experience of true transcendence or an indication of a god. If this were true then it would suggest that there is nothing beyond the physical, that spiritual awakenings are nothing other than evoked changes in the nervous system.

It should be noted that reported spiritual experiences most frequently involve changes in sensory experiences. We know that sensory experiences are produced by the nervous system. So, it would be expected that if a spiritual experience occurs then there would be changes in the nervous system. As a result it is not surprising that nervous system changes would accompany spiritual experiences.

Neural changes may represent the effects of spiritual experiences on the physical body. After all, when we become aware of any kind of remarkable occurrence we react emotionally, physically, and thoughtfully. This would imply that the neural changes occur after the spiritual experience and not before it as a causal relationship would demand. In addition, changing the brain with drugs may simply induce the same effects as the sequela of spiritual experience and not the spiritual experiences themselves.

The most common report of spiritual experience is that everything is perceived as one. This oneness experience is not reported to be a change in the actual sensory information, but rather as a perception of the interconnectedness of all things such that they are seen as all a part of a singular entity, like seeing individual waves as all being part of one ocean. The more modern science studies events and their interconnections the more that the truth of oneness is revealed. The entire science of ecology has developed to study the interconnectedness among biological entities, meteorology has determined that atmospheric conditions over the entire planet are interconnected, and geology has revealed the interconnectedness of all movement of the planet’s surface and interior. Just think how interconnected everything is with sunlight. Without this energy, life could not exist and even the weather would not be changing. Everything about us and our planet is interconnected to the sun’s energy.

So, perhaps the oneness revealed in spiritual experiences may actually be a more accurate glimpse of the truth of existence. Perhaps, the changes observed in the brain may simply be the effect of this revelation rather than the cause. At this point we cannot reach a clear conclusion as to whether spiritual experiences are material and physical or true revelation of a non-physical reality. But the research is exciting and will continue to explore these ultimate questions regarding existence.

Improve Social Anxiety Disorder with Mindfulness

Improve Social Anxiety Disorder with Mindfulness

By John M. de Castro, Ph.D.

“Using mindfulness, we can begin to notice what happens in the body when anxiety is present and develop strategies to empower clients to “signal safety” to their nervous system. Over time, clients feel empowered to slow down their response to triggers, manage their body’s fear response (fight-or-flight) and increase their ability to tolerate discomfort. The client experiences this as feeling like they have a choice about how they will respond to a trigger.” – Jeena Cho

It is a common human phenomenon that being in a social situation can be stressful and anxiety producing. This is particularly true when asked to perform in a social context such as giving a speech. Most people can deal with the anxiety and can become quite comfortable. But many do not cope well and the anxiety is overwhelming, causing the individual to withdraw. Social Anxiety Disorder (SAD) is characterized by a persistent, intense, and chronic fear of being watched and judged by others and feeling embarrassed or humiliated by their actions. This fear may be so severe that it interferes with work, school, and other activities and may negatively affect the person’s ability to form relationships.

SAD is the most common form of anxiety disorder and it is widespread, occurring in about 7% of the U.S. population and is particularly widespread among young adults. Anxiety disorders have generally been treated with drugs. But, there are considerable side effects and these drugs are often abused. There are a number of psychological therapies for SAD. Although, these therapies can be effective they are costly and because of availability, cost, and inconvenience, are only available to small numbers of sufferers. As a result, there is a growing trend to using group based therapy. But, about 45% of the patients treated do not respond to the therapy. So, there is a need to develop alternative treatments. Recently, it has been found that mindfulness training can be effective for anxiety disorders including Social Anxiety Disorder (SAD). Mindfulness-Based Stress Reduction (MBSR) contains three mindfulness trainings, meditation, body scan, and yoga, and has been shown to be effective in treating anxiety disorders. So, it would be reasonable to expect that MBSR training would improve the symptoms of Social Anxiety Disorder (SAD) in young adults.

In today’s Research News article “Group CBT versus MBSR for Social Anxiety Disorder: A Randomized Controlled Trial.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4837056/, Goldin and colleagues compared the efficacy of Group Cognitive Behavioral Therapy (Group-CBT) to Mindfulness-Based Stress Reduction (MBSR) program for the relief of Social Anxiety Disorder (SAD). They recruited through clinician referrals and community listings, patients who were diagnosed with SAD but had not been treated with drugs, CBT or MBSR in the recent past. In Group-CBT 6 patients met once a week for 2.5 hours over 12 weeks while the standard MBSR program was modified to include meetings of 6 patients once a week for 2.5 hours over 12 weeks. They were assigned in consecutive blocks of 6 patients to either Group-CBT, MBSR, or a wait-list control group. They were measured before and after treatment and every 3 months for the next year for social anxiety, emotion regulation, cognitive reappraisal self-efficacy, subtle avoidance, cognitive distortions, mindfulness, attention control, and rumination.

They found that compared to the wait-list control patients both Group-CBT and MBSR produced clinically significant improvements in social anxiety, increases in mindfulness, cognitive reappraisal, cognitive reappraisal self-efficacy, and attention control, and decreases in subtle avoidance, cognitive distortions, and rumination. There were no significant differences in the effectiveness of Group-CBT and MBSR and the effects appeared to last for a year afterward. Hence, both forms of therapy were highly effective and long-lasting for patients with Social Anxiety Disorder (SAD), improving emotions and thought processes.

It is interesting that the two therapies had such similar effects given that they target different processes. But, the results showed that both therapies equally improved the processes that are targeted by Group-CBT, thought processes, and the processes that are targeted by MBSR, mindfulness and attention. So, although designed to effect different processes the two therapies produced the same outcomes. Regardless, they were both highly effective in oriducing long-lasting improvements in the conditions of these patients suffering from SAD.

So, improve social anxiety disorder with mindfulness.

“The power of a mindfulness practice, however, may come in the realization that one can live a meaningful life even with social anxiety. (Participant) says that he still feels nervous in social situations but now feels compassion — not judgment — for himself, and sees that “I can be more the person I want to be.”’ – Jason Drwal

Study Summary

Goldin, P. R., Morrison, A., Jazaieri, H., Brozovich, F., Heimberg, R., & Gross, J. J. (2016). Group CBT versus MBSR for Social Anxiety Disorder: A Randomized Controlled Trial. Journal of Consulting and Clinical Psychology, 84(5), 427–437. http://doi.org/10.1037/ccp0000092

Abstract

Objective

To investigate treatment outcome and mediators of Cognitive-Behavioral Group Therapy (CBGT) vs. Mindfulness-Based Stress Reduction (MBSR) vs. Waitlist (WL) in patients with generalized social anxiety disorder (SAD).

Method

108 unmedicated patients (55.6% female; mean age = 32.7, SD = 8.0; 43.5% Caucasian, 39% Asian, 9.3% Hispanic, 8.3% other) were randomized to CBGT vs. MBSR vs. WL and completed assessments at baseline, post-treatment/WL, and at 1-year follow-up, including the Liebowitz Social Anxiety Scale – Self-Report (primary outcome) as well as measures of treatment-related processes.

Results

Linear mixed model analysis showed that CBGT and MBSR both produced greater improvements on most measures compared to WL. Both treatments yielded similar improvements in social anxiety symptoms, cognitive reappraisal frequency and self-efficacy, cognitive distortions, mindfulness skills, attention focusing and rumination. There were greater decreases in subtle avoidance behaviors following CBGT than MBSR. Mediation analyses revealed that increases in reappraisal frequency, mindfulness skills, attention focusing and attention shifting, and decreases in subtle avoidance behaviors and cognitive distortions mediated the impact of both CBGT and MBSR on social anxiety symptoms. However, increases in reappraisal self-efficacy and decreases in avoidance behaviors mediated the impact of CBGT (vs. MBSR) on social anxiety symptoms.

Conclusions

CBGT and MBSR both appear to be efficacious for SAD. However, their effects may be a result of both shared and unique changes in underlying psychological processes.

Improve Anxiety in Adolescents with Mindfulness

Improve Anxiety in Adolescents with Mindfulness

By John M. de Castro, Ph.D.

“Mindfulness also helps us to get to know our real self which is never a bad thing! People suffering from social anxiety are often marred by an exaggerated perception of their shortcomings which leads them to believe that they are inadequate and that everybody must be noticing. Practicing mindfulness based cognitive therapy will help them to reestablish a more realistic self-image.” – Kyle MacDonald

Anxiety disorders are the most common mental illness in the United States, affecting 40 million adults, or 18% of the population. Anxiety Disorders affects about 3.1% of the U.S. population. Severe anxiety affects about 6% of adolescents. Physically, anxiety sufferers will often show excessive fatigue, irritability, muscle tension or muscle aches, trembling, feeling twitchy, being easily startled, trouble sleeping, sweating, nausea, diarrhea or irritable bowel syndrome, and headaches.

Anxiety disorders in adults have generally been treated with drugs. It has been estimated that 11% of women in the U.S. are taking anti-anxiety medications. But, there are considerable side effects and these drugs are often abused. The drugs are also not appropriate for children and adolescents with developing nervous systems. So, there is a need to develop alternative treatments. Recently, it has been found that mindfulness training can be effective for anxiety disorders. Mindfulness-Based Cognitive Therapy (MBCT) has been shown to be effective in treating anxiety in adults. Mindfulness training has also been shown to produce changes in the nervous system. It is not known, however, what changes in the nervous system underlie the effect of MBCT on anxiety.

In today’s Research News article “Neural Function Before and After Mindfulness-Based Cognitive Therapy in Anxious Adolescents at Risk for Developing Bipolar Disorder.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4876535/, Strawn and colleagues examine the effects of Mindfulness-Based Cognitive Therapy (MBCT) on the nervous systems of youth with high levels of anxiety. They recruited children and adolescents, aged 9 to 16 years, who were diagnosed with an anxiety disorder and who were at risk for developing bipolar disorder. They were treated with a 12-week program of MBCT. Before and after the treatment they were measured for anxiety, clinical symptoms, and mindfulness and also underwent functional Magnetic Resonance (f-MRI) brain scans while performing a continuous processing task with emotional and neutral distractors.

They found that following MBCT there was a significant increase in activity of the insula, lentiform nucleus, and thalamus, and anterior cingulate cortex with the presentation of emotional pictures. So, MBCT produces changes in the brains of children and adolescents similar to those seen in adults. They also found that the greater the reduction in anxiety resulting from MBCT the greater the decrease in activity of the insula and anterior cingulate cortex.

The insula and the anterior cingulate cortex have been shown to be involved in emotional processing and MBCT is aimed at altering the thought processes revolving around the interpretations of emotions. So, the changes in the functional activity of these structures following MBCT are commensurate with the changes in emotionality. Hence, MBCT appears to change the brains of children and adolescents with anxiety disorders to improve emotional processing.

It should be noted that this was a pilot study with a very small number of participants and no control group. So, the findings must be interpreted with caution. But the findings are sufficiently interesting to justify conducting a larger randomized clinical trial in the future.

“If you have unproductive worries, you can train yourself to experience those thoughts completely differently. ‘You might think ‘I’m late, I might lose my job if I don’t get there on time, and it will be a disaster!’ Mindfulness teaches you to recognize, ‘Oh, there’s that thought again. I’ve been here before. But it’s just that—a thought, and not a part of my core self,‘” – Elizabeth Hoge

Journal of Child and Adolescent Psychopharmacology, 26(4), 372–379. http://doi.org/10.1089/cap.2015.0054

Abstract

Objective: We sought to evaluate the neurophysiology of mindfulness-based cognitive therapy for children (MBCT-C) in youth with generalized, social, and/or separation anxiety disorder who were at risk for developing bipolar disorder.

Methods: Nine youth (mean age: 13 ± 2 years) with a generalized, social, and/or separation anxiety disorder and a parent with bipolar disorder completed functional magnetic resonance imaging (fMRI) while performing a continuous processing task with emotional and neutral distractors (CPT-END) prior to and following 12 weeks of MBCT-C.

Results: MBCT-C was associated with increases in activation of the bilateral insula, lentiform nucleus, and thalamus, as well as the left anterior cingulate while viewing emotional stimuli during the CPT-END, and decreases in anxiety were correlated with change in activation in the bilateral insula and anterior cingulate during the viewing of emotional stimuli (p < 0.05, uncorrected; p < 0.005 corrected; cluster size, 37 voxels).

Conclusions: MBCT-C treatment in anxious youth with a familial history of bipolar disorder is associated with increased activation of brain structures that subserve interoception and the processing of internal stimuli—functions that are ostensibly improved by this treatment.

Improve Executive Function with Mindful Movement

Improve Executive Function with Mindful Movement

By John M. de Castro, Ph.D.

“Tai Chi may just be a form of exercise that will preserve a sharp mind!” – Tai Chi and Health

Human life is one of constant change. We revel in our increases in physical and mental capacities during development, but regret their decreases during aging. Over time there is a systematic progressive decline in every system in the body, the brain included. This includes our mental abilities which decline with age including impairments in memory, attention, and problem solving ability. It is inevitable and cannot be avoided. Using modern neuroimaging techniques, scientists have been able to view the changes that occur in the nervous system with aging. In addition, they have been able to investigate various techniques that might slow the process of neurodegeneration that accompanies normal aging. They’ve found that mindfulness practices reduce the deterioration of the brain that occurs with aging restraining the loss of neural tissue.

Mindfulness practices have been shown to improve cognitive processes and mood while gentle mindful movement exercises such as Tai Chi, Qigong and Baduanjin mind-body training have been shown to slow age related cognitive decline. But, most studies of mindful movement effects on cognitive decline and mood, are performed in the elderly. Hence, the effectiveness of these practices with younger people to enhance cognitive function and mood have not been extensively studied. In today’s Research News article “Baduanjin Mind-Body Intervention Improves the Executive Control Function.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5233682/, Chen and colleagues studied the effects of Baduanjin mind-body practice on mood and cognitive function of college students.

They recruited college students and randomly assigned them to receive either 8 weeks, 5 days per week, for 90 minutes per day of Baduanjin mind-body training or progressive muscle relaxation training. The Baduanjin mind-body training consisted of 8 movements for limbs, body-trunk, and eye movements. The participants were measured before and after training for mood and cognitive executive function with a flanker task. The flanker task required the participants to respond to the direction of an arrow when distracting arrows were present alongside the target arrow. This test for attention and filtering of irrelevant information. During the flanker task their brain activity was measured with near-infrared spectroscopy which measures blood flows in the brain.

They found that following Baduanjin mind-body training, but not relaxation training, there was a significant decrease in the levels of depression and increase in flanker task performance with incongruous distracting stimuli. The flanker task improvement demonstrated that the Baduanjin mind-body training participants were better able to filter out distracting material. In addition, during the flanker task, with distracting incongruent stimuli present, the Baduanjin mind-body training group had an increase in blood flow in the left prefrontal cortex while the relaxation group did not. This suggests that the Baduanjin mind-body training produced a change in the brain that may underlie the improvements in mood and executive function.

It has been demonstrated that increases in the activity and size of the prefrontal cortex occurs with improved executive function ability. This suggests that Baduanjin mind-body training changes the brain to improve cognitive function. It is quite remarkable that such a gentle practice can produce neural changes resulting in such beneficial effects. It is also important that these effects were produced in young participants. So, the benefits of participation in mindful movement programs are not restricted to the elderly and do not just protect against cognitive decline but can improve cognitive function even for those at the peak of their abilities.

Baduanjin mind-body training is a gentle practice, completely safe, can be used by anyone, including the elderly and sickly, is inexpensive to administer, can be performed in groups or alone, at home or in a facility or even public park, and can be quickly learned. In addition, it can also be practiced in social groups without professional supervision. This can make it fun, improving the likelihood of long-term engagement in the practice.

So, improve executive function with mindful movement.

Abstract

This study aims at comparing the effects of the Baduanjin mind-body (BMB) intervention with a conventional relaxation training program on enhancing the executive function. The study also attempts to explore the neural substrates underlying the cognitive effect of BMB intervention using near-infrared spectroscopy (NIRS) technique. Forty-two healthy college students were randomly allocated into either the Baduanjin intervention group or relaxation training (control) group. Training lasted for 8 weeks (90 min/day, 5 days/week). Each participant was administered the shortened Profile of Mood States to evaluate their mood status and the flanker task to evaluate executive function before and after training. While performing the flanker task, the NIRS data were collected from each participant. After training, individuals who have participated in BMB exercise showed a significant reduction in depressive mood compared with the same measure before the intervention. However, participants in the control group showed no such reduction. The before vs. after measurement difference in the flanker task incongruent trails was significant only for the Baduanjin intervention group. Interestingly, an increase in oxygenated hemoglobin in the left prefrontal cortex was observed during the Incongruent Trails test only after the BMB exercise intervention. These findings implicate that Baduanjin is an effective and easy-to-administering mind-body exercise for improving executive function and perhaps brain self-regulation in a young and healthy population.
