“While meditating the last day I finally could see love as an underlying force in the universe, and I had a waking dream of some fractal patterns realigning, it is hard to describe with words. It is still embarrassing to remember all the details of this, but it can be summarized with one word: delirium. I was totally out of myself, and what is worse, I was acting in inappropriate ways with other people. For instance, I was being hosted by a girl, and I acted violently smashing a cup against a wall, and throwing a chair to the floor. I still remember how my mind was watching in horror how my body was acting. It was stuff for nightmares…” – TLDR

There have been a number of reports that mindfulness meditation can lead to psychotic like symptoms in a few individuals. This appears to be amplified by participation in meditation retreats. It has been reported that around 60% of participants in intensive meditation retreats experienced at least one negative side effect, including panic, depression and confusion and about 7% experienced psychotic-like symptoms. Hence, meditation, although highly beneficial, does have some potential negative effects for many people and extreme negative consequences for a few.

There has, unfortunately been very little research on these negative effects of meditation. In today’s Research News article “Schizotypy and mindfulness: Magical thinking without suspiciousness characterizes mindfulness meditators.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5514306/, Antonova and colleagues, to address this issue, examine whether psychotic like symptoms are present in experienced meditators. They recruited male meditators who have been consistently practicing over at least 2 years, meditating at least 6 days per week for at least 45 minutes per day and males who had never practiced meditation and any other mindfulness practice. The participants were measured for five facets of mindfulness, including describing, observing, acting with awareness, non-judging, and non-reacting, and schizotypal personality characteristics, including ideas of reference, excessive social anxiety, magical thinking, unusual perceptual experiences, odd/eccentric behavior, no close friends, odd speech, constricted affect and suspiciousness.

They found that meditators had significantly lower scores on suspiciousness and excessive social anxiety, and higher scores on magical thinking. They were also higher in mindfulness, including observing, non-judging, and non-reacting. In addition, the higher the scores on acting with awareness and non-judging, the lower the levels of schizotypal personality characteristics including suspiciousness, excessive social anxiety, and constricted affect (blunted emotions). Hence, experienced meditators tend to have fewer psychotic-like symptoms and higher mindfulness and high levels of mindfulness were associated with lower psychotic-like symptoms.

These results are interesting and tend to counter the notion that meditation is associated with increased negative psychotic-like symptoms. This may be due, though, to the fact that people who meditate consistently over a long period of time are generally psychological healthy individuals to begin with. It is also possible that those individuals who are sensitive of the negative effects of meditation simply drop out and don’t continue meditating as the negative consequences present themselves. The higher levels of magical thinking in the meditators may result from the fact that the meditators all practiced in the Buddhist tradition where metaphysical ideas are taught.

This is an important line of research and could be best addressed with longitudinal research investigating beginning meditators and following their progress over an extended period of time. Unfortunately, the present results do not provide a clearer understanding of the potential hazards of meditation practice, particularly while engaging in meditation retreats. Perhaps research that closely follows meditators while participating in a retreat may help to elucidate the factors responsible for the reported negative consequences.

So, reduce psychotic symptoms with meditation.

Study Summary

Antonova, E., Amaratunga, K., Wright, B., Ettinger, U., & Kumari, V. (2016). Schizotypy and mindfulness: Magical thinking without suspiciousness characterizes mindfulness meditators. Schizophrenia Research: Cognition, 5, 1–6. http://doi.org/10.1016/j.scog.2016.05.001

Abstract

Despite growing evidence for demonstrated efficacy of mindfulness in various disorders, there is a continuous concern about the relationship between mindfulness practice and psychosis. As schizotypy is part of the psychosis spectrum, we examined the relationship between long-term mindfulness practice and schizotypy in two independent studies. Study 1 included 24 experienced mindfulness practitioners (19 males) from the Buddhist tradition (meditators) and 24 meditation-naïve individuals (all males). Study 2 consisted of 28 meditators and 28 meditation-naïve individuals (all males). All participants completed the Schizotypal Personality Questionnaire (Raine, 1991), a self-report scale containing 9 subscales (ideas of reference, excessive social anxiety, magical thinking, unusual perceptual experiences, odd/eccentric behavior, no close friends, odd speech, constricted affect, suspiciousness). Participants of study 2 also completed the Five-Facet Mindfulness Questionnaire which assesses observing (Observe), describing (Describe), acting with awareness (Awareness), non-judging of (Non-judgment) and non-reactivity to inner experience (Non-reactivity) facets of trait mindfulness. In both studies, meditators scored significantly lower on suspiciousness and higher on magical thinking compared to meditation-naïve individuals and showed a trend towards lower scores on excessive social anxiety. Excessive social anxiety correlated negatively with Awareness and Non-judgment; and suspiciousness with Awareness, Non-judgment and Non-reactivity facets across both groups. The two groups did not differ in their total schizotypy score. We conclude that mindfulness practice is not associated with an overall increase in schizotypal traits. Instead, the pattern suggests that mindfulness meditation, particularly with an emphasis on the Awareness, Non-judgment and Non-reactivity aspects, may help to reduce suspiciousness and excessive social anxiety.

Correct Brain Rhythms and Reduce Depression with Mindfulness

Correct Brain Rhythms and Reduce Depression with Mindfulness

By John M. de Castro, Ph.D.

“Mindfulness, or paying full attention to the present moment, can be very helpful in improving the cognitive symptoms of depression. . . Through mindfulness, individuals start to see their thoughts as less powerful. These distorted thoughts – such as “I always make mistakes” or “I’m a horrible person” – start to hold less weight. . . We ‘experience’ thoughts and other sensations, but we aren’t carried away by them. We just watch them come and go.” – Margarita Tartakovsky

Clinically diagnosed depression is the most common mental illness, affecting over 6% of the population. Major depression can be quite debilitating. It is also generally episodic, coming and going. Some people only have a single episode but most have multiple reoccurrences of depression. Depression can be difficult to treat and usually treated with anti-depressive medication. But, of patients treated initially with drugs only about a third attained remission of the depression. After repeated and varied treatments including drugs, therapy, exercise etc. only about two thirds of patients attained remission. But, drugs often have troubling side effects and can lose effectiveness over time. In addition, many patients who achieve remission have relapses and recurrences of the depression. Even after remission some symptoms of depression may still be present (residual symptoms).

Being depressed and not responding to treatment or relapsing is a terribly difficult situation. The patients are suffering and nothing appears to work to relieve their intense depression. Suicide becomes a real possibility. So, it is imperative that other treatments be identified that can be applied when the typical treatments fail. Mindfulness training is another alternative treatment for depression. It has been shown to be an effective treatment for depression and is also effective for the prevention of its recurrence. Mindfulness training is also known to change the nervous system.

The brain shows synchronous activity where large numbers of neural cells are active together in burst. This activity can be recorded in the electroencephalogram (EEG). They appear as oscillations (waves) in the electrical signals that occur at certain frequencies. Over time these frequencies are fairly stable which is reflected in a correlation over time of the waves. This is called Long-Range Temporal Correlations (LRTC). This signal changes with mental illness and brain disease. So, it is reasonable to study the LRTC in depressed patients and the effect of mindfulness training on it.

In today’s Research News article “Aberrant Long-Range Temporal Correlations in Depression Are Attenuated after Psychological Treatment.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5488389/, Gärtner and colleagues recruited depressed and healthy control patients and randomly assigned them to receive either 2 weeks of mindfulness training or education on stress reduction. Mindfulness training consisted of two 25-minute guided meditation per day for 6 days per week. The stress reduction education group was asked to rest on the same schedule. Before and after training they were measured for mental illness, depression, and rumination, and the EEG recorded at rest with eyes closed.

They found that the there was a significant elevation of the Long-Range Temporal Correlations (LRTC) in the depressed patients in the frontal and temporal cortices. In addition, mindfulness training, but not stress reduction education, produced a significant reduction in both depression and rumination. Further, after mindfulness training there was a significant reduction in the LRTC signal and the larger the reduction in the LRTC the greater the reduction in depression. Hence, they found that depression was associated with heightened neural synchrony and that mindfulness training reduced that synchrony to normal levels while relieving depression. These appeared to be related, as the larger the reduction, normalizing, in the synchrony the greater the reduction in depression.

These are interesting results that suggest that mindfulness training changes the brain in beneficial ways for depressed patients, normalizing the brain activity and the depressive symptoms. Mindfulness training has been previously demonstrated to reduce depression. The present results suggest how the training may be altering the brain to relieve depression by correcting aberrant brain activity in the frontal and parietal lobes of the brain. These results, however, only demonstrate that both brain activity and depression change after mindfulness training and does not demonstrate a causal connection between the brain activity and depression. It will remain for future research to investigate whether they are causally connected.

So, correct brain rhythms and reduce depression with mindfulness.

“Mindfulness practices of MBCT allowed people to be more intentionally aware of the present moment, which gave them space to pause before reacting automatically to others. Instead of becoming distressed about rejection or criticism, they stepped back to understand their own automatic reactions—and to become more attuned to others’ needs and emotions. Awareness gave them more choice in how to respond, instead of becoming swept up in escalating negative emotion.” – Emily Nauman

Aberrant Long-Range Temporal Correlations in Depression Are Attenuated after Psychological Treatment. Frontiers in Human Neuroscience, 11, 340. http://doi.org/10.3389/fnhum.2017.00340

Abstract

The spontaneous oscillatory activity in the human brain shows long-range temporal correlations (LRTC) that extend over time scales of seconds to minutes. Previous research has demonstrated aberrant LRTC in depressed patients; however, it is unknown whether the neuronal dynamics normalize after psychological treatment. In this study, we recorded EEG during eyes-closed rest in depressed patients (N = 71) and healthy controls (N = 25), and investigated the temporal dynamics in depressed patients at baseline, and after attending either a brief mindfulness training or a stress reduction training. Compared to the healthy controls, depressed patients showed stronger LRTC in theta oscillations (4–7 Hz) at baseline. Following the psychological interventions both groups of patients demonstrated reduced LRTC in the theta band. The reduction of theta LRTC differed marginally between the groups, and explorative analyses of separate groups revealed noteworthy topographic differences. A positive relationship between the changes in LRTC, and changes in depressive symptoms was observed in the mindfulness group. In summary, our data show that aberrant temporal dynamics of ongoing oscillations in depressive patients are attenuated after treatment, and thus may help uncover the mechanisms with which psychotherapeutic interventions affect the brain.

Improve Brain Processing of Cognitive Conflict with Mindfulness

Improve Brain Processing of Cognitive Conflict with Mindfulness

By John M. de Castro, Ph.D.

“Mindfulness should no longer be considered a “nice-to-have” for executives. It’s a “must-have”: a way to keep our brains healthy, to support self-regulation and effective decision-making capabilities, and to protect ourselves from toxic stress. When we take a seat, take a breath, and commit to being mindful, particularly when we gather with others who are doing the same, we have the potential to be changed.” – Christina Congleton

There is a tremendous amount of information present at any moment. It is a challenge to the nervous system to sort it out and pay attention to only the most significant information. This involves ignoring competing or conflicting stimuli and concentrating on only the most salient and pertinent stimuli. Mindfulness training can help. It involves a greater emphasis on attention to the immediate stimulus environment. So, it builds the capacity to focus on what is transpiring in the present moment. Mindful people generally have better attentional abilities and have fewer intrusive thoughts and less mind wandering. As a result, mindfulness has been shown to be associated with differences in thought processes.

One indirect method to monitor cognitive functions is through recording the electrical signals from the brain with the electroencephalogram (EEG). Electrical activity occurring at different frequencies is representative of the nature of the activity in the underlying brain tissue. The theta rhythm occurs in the frequency region of 4-7 cycles per second (Hz.). Recordings of Theta, particularly in the frontal regions of the brain have been shown to increase when attention is focused and mind wandering is minimized. Hence, the effects of mindfulness practice on the nervous may be seen in alterations to the Theta Rhythm in the frontal areas of the brain and the structures connected to them.

In today’s Research News article “Frontal Theta Dynamics during Response Conflict in Long-Term Mindfulness Meditators.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5461248/, Jo and colleagues recruited adult long-term (> 5 years) meditators (average 13.1 years) and non-meditators matched on gender and age. All participants had EEGs recorded while performing a flanker task, a measure of executive cognitive function, in which the participant has to respond to the direction of an arrow, when it is surrounded by distracting arrows that point either in the same (no-conflict) or opposite (conflict situation) directions.

They found that the meditators responded more accurately on the flanker task, making significantly fewer errors, particularly when the conflict situation was present. Hence, meditators demonstrated superior cognitive control and attentional ability. The Theta Rhythm power over the frontal areas was found to be higher for both groups during the conflict but not the no-conflict situation. The synchrony of the Theta Rhythm over the frontal areas and especially between the frontal areas and the motor cortex was greater for both groups during the conflict situation, but was significantly greater in the meditators. In addition, the greater the level of synchronization during the conflict situation the fewer the error made on the flanker task.

These are interesting results and suggest that long-term meditation practice enhances the individual’s cognitive and attentional ability particularly when conflicting stimuli are present. In addition, long-term meditation practice appears to alter the frontal areas of the nervous system enhancing their ability to resolve conflicts. So, meditation practice improves the brain and as a result the meditators cognitive attentional processing.

So, improve brain processing of cognitive conflict with mindfulness.

“Importantly, research has shown mindfulness to increase activity in brain areas associated with attention and emotion regulation. Mindfulness also facilitates neuroplasticity — the creation of new connections and neural pathways in the brain.” – Carolyn Gregoire

Abstract

Mindfulness meditators often show greater efficiency in resolving response conflicts than non-meditators. However, the neural mechanisms underlying the improved behavioral efficiency are unclear. Here, we investigated frontal theta dynamics—a neural mechanism involved in cognitive control processes—in long-term mindfulness meditators. The dynamics of EEG theta oscillations (4–8 Hz) recorded over the medial frontal cortex (MFC) were examined in terms of their power (MFC theta power) and their functional connectivity with other brain areas (the MFC-centered theta network). Using a flanker-type paradigm, EEG data were obtained from 22 long-term mindfulness meditators and compared to those from 23 matched controls without meditation experience. Meditators showed more efficient cognitive control after conflicts, evidenced by fewer error responses irrespective of response timing. Furthermore, meditators exhibited enhanced conflict modulations of the MFC-centered theta network shortly before the response, in particular for the functional connection between the MFC and the motor cortex. In contrast, MFC theta power was comparable between groups. These results suggest that the higher behavioral efficiency after conflicts in mindfulness meditators could be a function of increased engagement to control the motor system in association with the MFC-centered theta network.

Improve Creativity with Mindfulness

Improve Creativity with Mindfulness

By John M. de Castro, Ph.D.

“Mindfulness meditation is a great technique to learn to help improve creativity. There have been studies done specifically to measure the cognitive rigidity of people who meditate and their ability to solve problems in novel ways. The research shows non-meditators had greater cognitive rigidity than regular meditators, and they also had a tendency to apply difficult or outdated solutions to easy problems based on their past experiences, this was not the case for people who meditated.” – Bianca Rothschild

The problem solving ability of humans has been a key to their dominance of their environment. So, it’s important that we understand it and discover how to train it and maximize it. Problem solving most frequently involves logic and reasoning, sometimes along with mathematics. In this case focused attention is the key. The mind wandering off topic interferes with the concentration required for obtaining the solution. But, when a solution does not occur and the individual fails to solve the problem a completely different process transpires producing insight. If logic and reason fail, then fanciful and out-of-the box thinking may be needed. In this case mind wandering, taking the thought process away from the failed logical strategy, is superior, often producing a solution in a flash, an “aha” moment. In this case focused attention prevents the individual from seeing an unusual or creative solution. While the mind wandering off topic increases the discursive thinking that is required for obtaining the insightful solution.

Mindfulness is the ability to focus on what is transpiring in the present moment. It involves a greater emphasis on attention to the immediate stimulus environment. Mindful people generally have better attentional abilities and have fewer intrusive thoughts and less mind wandering. As a result, mindfulness has been shown to be associated with differences in thought processes. Most of the time these differences are associated with beneficial results, but sometimes they can lead to negative outcomes including a greater tendency to have false memories. So mindfulness should improve problem solving involving logic, reason, and focused attention, while it should interfere with insightful, creative problem solving.

These two forms of problem solving are, in general, associated with different neural systems. Focused attention involves a number of brain structures centered in the frontal lobes. Creative, discursive thinking involves a system of structures known as the Default Mode Network (DMN) involving the parietal lobe, cingulate cortex, and insula. One way to investigate the influence of mindfulness on creative problem solving is to look at the activity of the Default Mode Network (DMN) during creative problem solving and insight in practitioners with varying amounts of mindfulness training.

In today’s Research News article “Creativity Is Enhanced by Long-Term Mindfulness Training and Is Negatively Correlated with Trait Default-Mode-Related Low-Gamma Inter-Hemispheric Connectivity.” (See summary below). Berkovich-Ohana and colleagues recruited non-meditators and meditators with short (180-1430 hours), intermediate (1740-2860 hours), and long-term (3870-23,000 hours) meditation practice. Divergent creative thinking was measured with the alternative uses task which requires participants to generate as many and unusual uses of conventional, everyday objects. While the participants were engaged in the creativity measurements the Electroencephalogram (EEG) was recorded from the scalp.

They found that the intermediate and long-term meditators, compared to the non-meditators and short-term meditators, had significantly greater performance on the creative thinking task including a greater number of alternative uses (fluency) and a greater number of categories (flexibility) of alternative uses. Further, they found that the lower the EEG activity in the gamma frequency range between brain hemispheres the greater the creative thinking. These results suggest that meditation practice alters brain processing, changing the interhemispheric connectivity of the DMN to improve creative thinking.

The study found that meditation practice improves creative thinking which is related to lower functional connectivity for the Default Mode Network (DMN). This, in turn, suggests that the lower ability of the mind wandering system of the brain to affect other brain regions the better the creative thinking. Hence, suppressing mind wandering while engaged in the alternative uses creative thinking task improves creative thinking.

So, improve creativity with mindfulness.

“A central aspect of creativity is divergent thinking, which refers to the ability to come up with lots of different ideas. . . . there is a small influence of mindfulness techniques on divergent thinking. That is, people who engage in mindfulness exercises tend to do a better job of generating more ideas than those who do not. They are better, but not much better.” – Art Markman

Abstract

It is becoming increasingly accepted that creative performance, especially divergent thinking, may depend on reduced activity within the default mode network (DMN), related to mind-wandering and autobiographic self-referential processing. However, the relationship between trait (resting-state) DMN activity and divergent thinking is controversial. Here, we test the relationship between resting-state DMN activity and divergent thinking in a group of mindfulness meditation practitioners. We build on our two previous reports, which have shown DMN activity to be related to resting-state log gamma (25–45 Hz) power and inter-hemispheric functional connectivity. Using the same cohort of participants (three mindfulness groups with increasing expertise, and controls, n = 12 each), we tested (1) divergent thinking scores (Flexibility and Fluency) using the Alternative Uses task and (2) correlation between Alternative Uses scores and DMN activity as measured by resting-state gamma power and inter-hemispheric functional connectivity. We found that both Fluency and Flexibility (1) were higher in the two long-term mindfulness groups (>1000 h) compared to short-term mindfulness practitioners and control participants and (2) negatively correlated with gamma inter-hemispheric functional connectivity (frontal-midline and posterior-midline connections). In addition, (3) Fluency was significantly correlated with mindfulness expertise. Together, these results show that long-term mindfulness meditators exhibit higher divergent thinking scores in correlation with their expertise and demonstrate a negative divergent thinking—resting-state DMN activity relationship, thus largely support a negative DMN-creativity connection.

Improve Emotional Well-Being with Mindfulness

Improve Emotional Well-Being with Mindfulness

By John M. de Castro, Ph.D.

“Mindfulness is about offering a warm, kind, friendly, accepting awareness to your moment-by-moment experience (all positive emotions), whatever that may be. For this reason, any practice of mindfulness, in the long term, develops your ability to generate positive feeling towards your inner (thoughts, emotions) and outer (world) experience.” – Anonymous

Mindfulness practice has been shown to produce improved emotion regulation. Practitioners demonstrate the ability to fully sense and experience emotions, but respond to them in more appropriate and adaptive ways. In other words, mindful people are better able to experience yet control emotions. This is a very important consequence of mindfulness. Humans are very emotional creatures and these emotions can be very pleasant, providing the spice of life. But, when they get extreme they can produce misery and even mental illness. The ability of mindfulness training to improve emotion regulation is thought to be the basis for a wide variety of benefits that mindfulness provides to mental health and the treatment of mental illness especially depression and anxiety disorders.

Two types of meditation practices are the commonly used. Loving kindness meditation is designed to develop kindness and compassion to oneself and others. The individual systematically pictures different individuals from self, to close friends, to enemies and wishes them happiness, well-being, safety, peace, and ease of well-being. In mindfulness meditation, the individual either practices paying attention to a single meditation object, or the individual opens up awareness to everything that’s being experienced regardless of its origin. In both cases, the meditator learns to filter out distracting stimuli, including thoughts, staying focused on the present moment, and filtering out thoughts centered around the past or future. The meditator just observes the stimuli present and lets them arise, and fall away without paying them any further attention.

There has been very little research on the relative effectiveness of these two very different types of meditation practice. In addition, there has been little attention paid to the growth and development in the benefits of practice over time. In today’s Research News article “Positive Emotion Correlates of Meditation Practice: a Comparison of Mindfulness Meditation and Loving-Kindness Meditation.” (See summary below). Fredrickson and colleagues compare Loving kindness meditation to mindfulness meditation practice effects on the growth of positive emotions as practice continues.

They recruited meditation-naive adults between the ages of 34 to 64 years and randomly assigned them to a wait-list control group or to receive 1-hour once per week for 6 weeks training in either loving kindness meditation or mindfulness meditation. Participants were asked to practice at home 3 to 5 times per week. Beginning with the start of training, participants completed daily on-line reports for 9 weeks of their meditation practice and their emotional states of 10 positive emotions (amusement, awe, gratitude, hope, inspiration, interest, joy, love, pride, and serenity) and 10 negative emotions (anger, shame, fear, hate, disgust, embarrassment, guilt, sadness, scorn, and stress).

They found that the participants in both meditation conditions had significant increases in positive emotions and the groups did not differ. Negative emotions were not affected. Hence, both loving kindness meditation and mindfulness meditation improved the participants mood equivalently. The improvements in positive emotions increased linearly over the 9 weeks of measurement, with the emotional state becoming more and more positive every day. They also found that the more the participants practiced the larger the improvements in their positive emotional states.

These are interesting results that indicate that meditation, regardless of type, leads to greater happiness and the more practice, both in frequency and duration, the greater the benefit which grows day by day. It would be interesting in future studies to continue collecting data for a longer period of time to determine when the growth in benefits begins to taper off. The fact that there was no effect on negative emotions may have been due to the fact that these otherwise normal participants did not have very high levels of negative emotions to start with. Again, future research should include individuals with high levels of negative emotions. Regardless, it is clear that meditation practice incrementally improves mood with continued practice.

So, improve emotional well-being with mindfulness.

Abstract

The purpose of this study was to uncover the day-to-day emotional profiles and dose-response relations, both within persons and between persons, associated with initiating one of two meditation practices, either mindfulness meditation or loving-kindness meditation. Data were pooled across two studies of midlife adults (N = 339) who were randomized to learn either mindfulness meditation or loving-kindness meditation in a 6-week workshop. The duration and frequency of meditation practice was measured daily for 9 weeks, commencing with the first workshop session. Likewise, positive and negative emotions were also measured daily, using the modified Differential Emotions Scale (Fredrickson, Advances in Experimental Social Psychology 47:1–53, 2013). Analysis of daily emotion reports over the targeted 9-week period showed significant gains in positive emotions and no change in negative emotions, regardless of meditation type. Multilevel models also revealed significant dose-response relations between duration of meditation practice and positive emotions, both within persons and between persons. Moreover, the within-person dose-response relation was stronger for loving-kindness meditation than for mindfulness meditation. Similar dose-response relations were observed for the frequency of meditation practice. In the context of prior research on the mental and physical health benefits produced by subtle increases in day-to-day experiences of positive emotions, the present research points to evidence-based practices—both mindfulness meditation and loving-kindness meditation—that can improve emotional well-being.

Improve Responses to Negative Emotions with Meditation

Improve Responses to Negative Emotions with Meditation

By John M. de Castro, Ph.D.

“Stress and anxiety can cause any number of mental health issues, which can in turn lead to physical health issues (substance abuse springs immediately to mind). We’ve known for some time that meditation can help with many of these problems.” – Anne Green

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 areas. In other words, meditation practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits. Hence, the ability of mindfulness practices to improve emotional regulation should be reflected in relatively permanent changes in the nervous system that should become evident in the responses of the nervous system to emotional stimuli.

Emotions are usually measured by self-report. But, because emotional reactivity includes physiological reactions, emotional responses can be measured with these reactions. An interesting index is the response of the pupil of the eye. The dilation (enlargement) of the pupil is controlled by the sympathetic nervous system, while its constriction (narrowing) is controlled by the parasympathetic nervous system. Since, sympathetic response reflects activation while the parasympathetic response reflects relaxation, the dilation and constriction of the pupil can provide a measure of the individual’s nervous system response to the immediate situation.

In today’s Research News article “Pupillary Response to Negative Emotional Stimuli Is Differentially Affected in Meditation Practitioners.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5413546/, Vasquez-Rosati and colleagues employ the pupillary response to gauge the nervous system response to emotional stimuli and how than may be modified in people who meditate. They compared meditators to non-meditators in their emotional ratings, heart rate, and pupillary response to pictures whose content was either emotionally positive, negative, or neutral.

They found that the meditators had a lower overall heart rate and rated all images as more positive than the non-meditators. In addition, the meditators rated the negative images as less activating. These results suggest that the meditators are more relaxed, generally respond more positively to everything, and are less reactive to negative situations. This was reflected in the pupillary response to negative images where the meditators showed initially a stronger constriction of the pupil followed by a weaker dilation than the non-meditators. This suggests that the meditators had a greater parasympathetic response and a diminished sympathetic response to negative stimuli than the non-meditators.

These results suggest that meditation practice alters the nervous system to produce greater relaxation and more positive responses to the world in general. This can be seen in the lower stress levels and better overall moods observed in meditators. Meditation also appears to alter the brains response to negative emotions, emphasizing parasympathetic responding, making it less responsive and activating. These are interesting results that suggest how mindfulness training may be altering nervous system responses to improve emotion regulation.

So, improve responses to negative emotions with meditation.

Abstract

Clinically, meditative practices have become increasingly relevant, decreasing anxiety in patients and increasing antibody production. However, few studies have examined the physiological correlates, or effects of the incorporation of meditative practices. Because pupillary reactivity is a marker for autonomic changes and emotional processing, we hypothesized that the pupillary responses of mindfulness meditation practitioners (MP) and subjects without such practices (non-meditators (NM)) differ, reflecting different emotional processing. In a group of 11 MP and 9 NM, we recorded the pupil diameter using video-oculography while subjects explored images with emotional contents. Although both groups showed a similar pupillary response for positive and neutral images, negative images evoked a greater pupillary contraction and a weaker dilation in the MP group. Also, this group had faster physiological recovery to baseline levels. These results suggest that mindfulness meditation practices modulate the response of the autonomic nervous system, reflected in the pupillary response to negative images and faster physiological recovery to baseline levels, suggesting that pupillometry could be used to assess the potential health benefits of these practices in patients.

Relieve Anxiety following Surgery with Meditation

Relieve Anxiety following Surgery with Meditation

By John M. de Castro, Ph.D.

“Mindfulness trains you to view your thoughts differently. You learn to recognize and stop “mental time travel” — worrying about the future and ruminating about the past. Instead of following a worrying thought down the path of all possible negative outcomes, you learn to recognize it for what it is — one thought — and then let it go. This trains your brain to be less anxious.” – Deane Alban

It’s a normal human response to become anxious when confronted with highly stressful or frightening situations, such as undergoing heart surgery. Being overly anxious, however, can interfere with coping and recovery after surgery. It has been demonstrated repeatedly that mindfulness counteracts anxiety and mindfulness training is an effective treatment for a variety of forms of anxiety. Mindfulness training has been shown to be effective for anxiety disorders in general and in relieving test anxiety and social anxiety. It has yet to be demonstrated that mindfulness training can relieve the anxiety preceding and following major surgery.

In today’s Research News article “.” See summary below or view the full text of the study at:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5408519/, Kiran and colleagues examine the ability of meditation training to relieve anxiety before and after coronary artery bypass grafting. They recruited patients (average age of 55 years) who were scheduled to undergo coronary artery bypass grafting for coronary artery disease and randomly assigned them to either receive meditation training or counseling about the surgical procedure. The mindfulness training occurred upon admission to the hospital and consisted of three instructional sessions on Rajyoga meditation and 3 10-minute meditations per day, once before breakfast, lunch, and dinner. Meditation continued daily prior to and following surgery. Prior to training anxiety was measured with a self-report and on the day of surgery and 2 and 5 days later anxiety and plasma cortisol levels (to measure stress responding) were measured.

They found that before training and right before surgery the groups did not differ in anxiety levels. But, on the 2^nd day after surgery the meditation group was significantly less anxious than the control group and on the 5^th postoperative day the difference was even greater. Before surgery plasma cortisol levels did not differ between groups but the meditation group had a significantly smaller increase in cortisol immediately after surgery and a return to the normal range on the 5^th postoperative day. Hence, meditation appears to lower postsurgical anxiety and stress levels. This may promote faster recovery from the procedure. It is interesting that such a simple and short-term mindfulness intervention can have such a large effect on anxiety and stress responding.

Anxiety is a fear of potential future negative events. It is dependent upon future oriented thought processes. Mindfulness training may counteract this by focusing the individual on the present moment. Since, there are no negative events there in the present moment, anxiety dissipates. In addition, mindfulness training improves the individual’s ability to see the negative future projections as they arise in the mind and recognize that they are not based in present reality. This can lead to reduced anxiety.

So, relieve anxiety following surgery with meditation.

“We have a bad habit of gathering up dramatic feelings and situations, clutching them to us as if they were prized possessions. We feel we are entitled to our ownership of this anxiety, and we believe we must hold onto it in order to keep ourselves emotionally safe. It takes a little courage, but meditation can help us see and nurture our internal strength, so we can separate ourselves from drama and achieve anxiety relief.” – Ram Das

The Role of Rajyoga Meditation for Modulation of Anxiety and Serum Cortisol in Patients Undergoing Coronary Artery Bypass Surgery: A Prospective Randomized Control Study. Annals of Cardiac Anaesthesia, 20(2), 158–162. http://doi.org/10.4103/aca.ACA_32_17

Abstract

Introduction:

Rajyoga meditation is a form of mind body intervention that is promoted by the Brahma Kumaris World Spiritual University. This form of meditation can be easily performed without rituals or mantras and can be practiced anywhere at any time. The practice of Rajyoga meditation can have beneficial effects on modulating anxiety and cortisol level in patients undergoing major cardiac surgery.

Materials and Methods:

A prospective randomized control study was carried out in a single tertiary care center. One hundred and fifty patients undergoing elective coronary artery bypass surgery were enrolled in the study. The patients were randomized in two groups namely, Group 1 (Rajyoga group) and Group 2 (Control Group). Anxiety was measured on a visual analog scale 1–10 before the start of Rajyoga training or patient counseling (T1), on the morning of the day of surgery (T2), on the 2nd postoperative day (T3), and on the 5th postoperative day (T4). The serum cortisol level was measured in the morning of the day of surgery (T1), on the 2nd postoperative day (T2) and on the 5th postoperative day (T3), respectively.

Results:

In the study, it was seen that the anxiety level of the patients before the surgery (T1) and on the day of surgery (T2) were comparable between the two groups. However on the 2nd postoperative day (T3), the patients who underwent Rajyoga training had lower anxiety level in comparison to the control group (3.12 ± 1.45 vs. 6.12 ± 0.14, P < 0.05) and on the 5th postoperative day (T4) it was seen that Rajyoga practice had resulted in significant decline in anxiety level (0.69 ± 1.1 vs. 5.6 ± 1.38, P < 0.05). The serum cortisol level was also favorably modulated by the practice of Rajyoga meditation.

Conclusion:

Mindbody intervention is found to effective in reducing the anxiety of the patients and modulating the cortisol level in patients undergoing wellknown stressful surgery like coronary artery bypass surgery.

Meditation Practice Alters Brain Networks in the Elderly

Meditation Practice Alters Brain Networks in the Elderly

By John M. de Castro, Ph.D.

“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

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. 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.

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.

The changes in the aging brain produced by meditation are not a simple increases in tissue throughout the brain but rather increases in some area and systems and decreases in others. In today’s Research News article “A longitudinal study of the effect of short-term meditation training on functional network organization of the aging brain.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5428857/, Cotier and colleagues studied the neuroplastic changes in brain systems produced by meditation in the elderly. They recruited health elderly participants (average age of years) and randomly assigned them to receive either 8 weeks of meditation or relaxation training. Training occurred in 22 90-minute group classes. “Meditation participants were taught to cultivate mindfulness through paying attention to the surrounding sounds and one’s own breathing, feelings and sensations on the present moment.” “Relaxation participants were taught diaphragmatic breathing, progressive muscle relaxation and imagery relaxation techniques aimed at enhancing body awareness and reducing body tension.”

Before and after training the participants underwent functional Magnetic Resonance Imaging (fMRI) scanning of their brains. They found that after 8-weeks of meditation practice there was reduced functional connectivity in the default mode network (DMN), salience network (SN), and somatomotor network (SMN) while after relaxation training these same systems showed increased functional connectivity. Also, in the meditation group “there was decreased connectivity strength between the DMN and other modules.”

These are very interesting results as the Default Mode Network (DMN) becomes active during wind wandering and relatively quiet during focused on task behavior. It is involved when we are engaged in internally focused tasks such as recalling deeply personal memories, daydreaming, sleeping, imagining the future and trying to take the perspective of others. The DMN involves neural structures including the medial prefrontal cortex, anterior and posterior cingulate cortices, precuneus, inferior parietal cortex, and lateral temporal cortex. These areas of the DMN are functionally connected, such that they are simultaneously active during mind wandering.

Hence the current results of reduced functional connectivity in the DMN and between the DMN and other neural systems suggests that the meditation practice resulted in changes in the brain reflective of decreased mind wandering and increased focused attention. These changes can be helpful to the elderly who demonstrate increasing difficulties with attention. These changes may underlie the ability of meditation practice to reduce cognitive decline in the elderly. Hence, they suggest that meditation practice by the elderly can change their nervous systems in beneficial ways, decreasing the tendency for the mind to wander away from the task at hand and improving attentional ability and thereby reducing the deterioration of thought processes.

So, alter brain networks in the elderly with meditation practice.

“at a time when Americans are living longer than ever before but experiencing higher rates of Alzheimer’s and other neurodegenerative disorders, the research is an important reminder that mindfulness can exert a long-lasting influence on brain health.” – Carolyn Gregoire

Abstract

The beneficial effects of meditation on preserving age-related changes in cognitive functioning are well established. Yet, the neural underpinnings of these positive effects have not been fully unveiled. This study employed a prospective longitudinal design, and graph-based analysis, to study how an eight-week meditation training vs. relaxation training shaped network configuration at global, intermediate, and local levels using graph theory in the elderly. At the intermediate level, meditation training lead to decreased intra-connectivity in the default mode network (DMN), salience network (SAN) and somatomotor network (SMN) modules post training. Also, there was decreased connectivity strength between the DMN and other modules. At a local level, meditation training lowered nodal strength in the left posterior cingulate gryus, bilateral paracentral lobule, and middle cingulate gyrus. According to previous literature, the direction of these changes is consistent with a movement towards a more self-detached viewpoint, as well as more efficient processing. Furthermore, our findings highlight the importance of considering brain network changes across organizational levels, as well as the pace at which these changes may occur. Overall, this study provides further support for short-term meditation as a potentially beneficial method of mental training for the elderly that warrants further investigation.

Women Benefit More than Men from Mindfulness

Women Benefit More than Men from Mindfulness

By John M. de Castro, Ph.D.

“For people that tend to be willing to confront or expose themselves or turn toward the difficult, mindfulness is made for helping that process. For people who have been largely turning their attention away from the difficult, to suddenly bring all their attention to their difficulties can be somewhat counterproductive. While facing one’s difficulties and feeling one’s emotions may seem to be universally beneficial, it does not take into account that there may be different cultural expectations for men and women around emotionality.” – Willoughby Britton

Mindfulness training has been shown to be beneficial for a variety of mental health problems, including anxiety, depression, Antisocial Personality Disorder, Borderline personality disorder, impulsivity, obsessive compulsive disorder, phobias, post-traumatic stress disorder , sexual dysfunction, suicidality and even with psychosis. It also improves the psychological well-being of healthy people. Interestingly, there appears to be differences between men and women in the occurrence of various mental illnesses. Women have a much higher incidence of emotional issues than men such as anxiety and depression. On the other hand, men are more likely to have conduct disorders and substance abuse.

One of the ways that mindfulness appears to work to improve mental health is by improving emotion regulation. This increases the individual’s ability to fully experience emotions but react to and cope with them adaptively, in other words, not to be carried away by them. Since women are more likely to have emotional issues than men, and mindfulness is particularly effective in improving emotion regulation, it would seem reasonable to hypothesize that mindfulness would have greater psychological benefits for women than for men.

In today’s Research News article “Women Benefit More Than Men in Response to College-based Meditation Training.” See summary below or view the full text of the study at:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5397480/, Rojiana and colleagues recruited male and female university students and trained them for 12 weeks, 3 times per week for 1 hour, in focused and open monitoring meditation. They completed measurements before and after training of mindfulness, positive and negative emotions, and self-compassion. They then compared the effectiveness of the meditation training for men and women.

They found that after training both men and women improved in mindfulness and self -compassion, but women had greater improvements than men in mindfulness and the mindfulness facets of observing, describing, non-judging, and non-reacting. Women also showed greater decreases in negative emotions. For women, it was found that the greater the increase in mindfulness, the greater the decrease in negative emotions. Hence, they found that women tended to benefit more from the meditation training that the men.

These are interesting results that suggest that women respond to meditation training with greater improvements in emotions and mindfulness than men. This may well have occurred due to the facts that mindfulness is known to improve emotion regulation and women have greater problems with emotion regulation and thereby benefit more. The greater improvements in mindfulness in women are interesting and may be due to the fact that the women were lower in mindfulness, particularly non-reactivity, to begin with. The meditation simply increased their levels of mindfulness to those of the men. This suggests that women have a greater tendency to react emotionally and that mindfulness training by decreasing this reactivity has greater benefits for women.

The results might have been different had the study measured behavioral conduct and externalizing behaviors rather than emotions. In a sense, the study played right to the issues than most trouble women and didn’t measure those that are more characteristic of males. Had they measured these factors perhaps they would have seen greater improvement in men rather than women. Regardless, women appear to benefit more emotionally from mindfulness training than men.

“When thrown by their feelings, men tend to “externalize” their emotions by doing things like working out, playing video games or otherwise interacting with their outer worlds. Women tend to “internalize” by analyzing and ruminating over their emotional states, psychologists say. While many men go outward — and one might argue, distract themselves from their internal world — women go inward.” – Drake Baer

Abstract

Objectives: While recent literature has shown that mindfulness training has positive effects on treating anxiety and depression, there has been virtually no research investigating whether effects differ across genders—despite the fact that men and women differ in clinically significant ways. The current study investigated whether college-based meditation training had different effects on negative affect for men and women.

Methods: Seventy-seven university students (36 women, age = 20.7 ± 3.0 years) participated in 12-week courses with meditation training components. They completed self-report questionnaires of affect, mindfulness, and self-compassion before and after the course.

Results: Compared to men, women showed greater decreases in negative affect and greater increases on scales measuring mindfulness and self-compassion. Women’s improvements in negative affect were correlated to improvements in measures of both mindfulness skills and self-compassion. In contrast, men showed non-significant increases in negative affect, and changes in affect were only correlated with ability to describe emotions, not any measures of experiential or self-acceptance.

Conclusion: These findings suggest that women may have more favorable responses than men to school-based mindfulness training, and that the effectiveness of mindfulness-based interventions may be maximized by gender-specific modifications.
