Improve Migraine Headache with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Stress is a migraine trigger for nearly 70% of people living with migraine and disorders that cause severe head pain. Simple mindfulness exercises and relaxation techniques can help alleviate stress, increase calmness and, in some cases, prevent a migraine attack.” – Shirley Kessel

 

Migraine headaches are a torment far beyond the suffering of a common headache. It is an intense throbbing pain usually unilateral, focused on only one side of the head and lasts from 4 hours to 3 days. They are actually a collection of neurological symptoms. Migraines often include: visual disturbances, nausea, vomiting, dizziness, extreme sensitivity to sound, light, touch and smell, and tingling or numbness in the extremities or face. Migraines are the 8th most disabling illness in the world. While most sufferers experience attacks once or twice a month, about 4% have chronic daily headaches. Migraines are very disruptive to the sufferer’s personal and work lives as most people are unable to work or function normally when experiencing a migraine.

 

There is no known cure for migraine headaches. Treatments are targeted at managing the symptoms. Prescription and over-the-counter pain relievers are frequently used. There are a number of drug and drug combinations that appear to reduce the frequency of migraine attacks. These vary in effectiveness but unfortunately can have troubling side effects and some are addictive. Behaviorally, relaxation and sleep appear to help lower the frequency of migraines. Mindfulness practices have been shown to reduce stress and improve relaxation. So, they may be useful in preventing migraines. Indeed, it has been shown that mindfulness practice can reduce headache pain. The research is accumulating. So, it makes sense to summarize what has been learned.

 

In today’s Research News article “Mindfulness in migraine: A narrative review.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7213534/ ) Wells and colleagues review and summarize the published research on the effectiveness of mindfulness-based interventions for the relief of migraine headaches. They identified 8 published studies.

 

They report that the published studies found that mindfulness-based interventions produced significant improvements in patients with migraine headaches in regards to their overall quality of life and disability, self-efficacy and psychological symptoms over headache frequency. They also found that these mindfulness-based interventions work well in combination with pharmacologic treatments.

 

It is not known exactly how mindfulness produces these benefits for the patients with migraine headaches. The authors suggest that mindfulness may work as a result of decreasing pain perception, better coping mechanisms, greater body awareness, lowering reactivity, decreasing inflammation, improving stress coping, and modulating the autonomic nervous system. Regardless it is clear that mindfulness-based interventions do not cure migraines but rather improve the quality of life and reduce the disability of the patients. In combination with pharmacologic treatments mindfulness-based interventions work even better. Migraine headache is a torment. So, the relief produced by mindfulness-based interventions is very important for relieving the suffering of the patients.

 

So, improve migraine headache with mindfulness.

 

“Many people with migraine have brains that are more sensitive to change, whether it be changes inside us such as hydration or hormone levels or outside changes such as stress or even weather conditions. Daily mindfulness practice may help to settle these fluctuations and calm the mind which could have a beneficial effect on migraine. It can also be useful during a migraine attack to reduce the impact of the pain.” – David Kernick

Abstract

Introduction:

Migraine is the second leading cause of disability worldwide, yet many patients are unable to tolerate, benefit from, or afford pharmacological treatment options. Non-pharmacological migraine therapies exist, especially to reduce opioid use, which represents a significant unmet need. Mindfulness-based interventions (MBI) have potential as a non-pharmacological treatment for migraine, primarily through the development of flexible attentional capacity across sensory, cognitive, and emotional experiences.

Areas Covered:

We review efficacy and potential mechanisms of MBIs for migraine, including mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT).

Expert Opinion:

While most mindfulness research studies for migraine to date have been pilot trials, which are small and/or lacked rigor, initial evidence suggests there, may be improvements in overall headache-related disability and psychological well-being. Many research questions remain to help target the treatment to patients most likely to benefit, including the ideal dosage, duration, delivery method, responder characteristics, and potential mechanisms and biomarkers. A realistic understanding of these factors is important for patients, providers, and the media. Mindfulness will not “cure” migraine; however, mindfulness may be an important tool as part of a comprehensive treatment approach to help patients “mindfully” engage in valued life activities.

Spirituality Improves Posttraumatic Growth with Mothers of Children with Cancer

 

By John M. de Castro, Ph.D.

 

“spirituality can play a critical role in the way traumas are understood, how they are managed, and how they are ultimately resolved.” – Kenneth Pargamen

 

Modern living is stressful under the best of conditions. But dealing with the trauma of having a child with cancer the levels of stress and anxiety are markedly increased. It is important for people to engage in practices that can help them control their responses to the stress and their levels of anxiety. Spirituality, a sense of inner peace and harmony, and religiosity are known to help with a wide range of physical and psychological problems. It is not known if spirituality affects the symptoms or posttraumatic growth produced by the trauma of having a child with cancer.

 

In today’s Research News article “Posttraumatic Growth and Spirituality in Mothers of Children with Pediatric Cancer.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7999482/ ) Czyżowska and colleagues recruited mothers of children (average age of 6.4 years) who were in the hospital being treated for cancer. They completed measures of post-traumatic growth, including changes in self-perception, changes in relationships with others, appreciation of life, and spiritual changes; and spirituality including religious attitudes, ethical sensitivity, and harmony.

 

They found that the higher the levels of spirituality, including ethical sensitivity, and harmony, the higher the levels of post-traumatic growth including relationships with others, and spiritual changes. The highest levels of post-traumatic growth that the mothers had were in in appreciation of life. In addition, the mothers with the greatest changes in post-traumatic growth had significantly higher levels of spirituality.

 

These results suggest that mothers of children with pediatric cancer demonstrate post-traumatic growth, especially in appreciation of life. In addition, they found that this post-traumatic growth was associated with spirituality. It is interesting that religious attitudes were not associated with growth. Hence, having inner peace and harmony (spirituality) and not religiosity is associated with growth. This raises the possibility that treating mothers’ spirituality may assist them in coping with pediatric cancer. Being better able to cope with the stresses should allow the mothers to better work with their children, promoting their health and well-being.

 

So, spirituality improves posttraumatic growth with mothers of children with cancer.

 

“positive religious coping, religious openness, readiness to face existential questions, religious participation, and intrinsic religiousness are typically associated with posttraumatic growth.” – Annick Shaw

Abstract

A child’s cancer, as a life-threatening illness, is classified as a traumatic event both for the child him-/herself and for his/her relatives. Struggling with a traumatic experience can bring positive consequences for an individual, which is referred to as posttraumatic growth. The aim of this study was to explore the relationship between posttraumatic growth and spirituality understood as a personal resource in mothers of children with pediatric cancer. In total, 55 mothers whose children were in the phase of treatment and who had been staying with them in the hospital filled in a Posttraumatic Growth Inventory, Self-description Questionnaire of Spirituality, and the author’s short questionnaire on demographic variables and information on the child and his/her disease. A high level of posttraumatic development, especially in the area of life appreciation, was observed in the examined mothers. Spirituality was positively related to the emergence of positive change, in two particular components, ethical sensitivity and harmony. It seems that taking into account the area of spirituality when planning interventions and providing support in this group could foster coping with the situation and emergence of posttraumatic growth.

Yoga Improves Resident Physician Psychological Health But Doesn’t Appear to be Feasible and Acceptable.

Yoga Improves Resident Physician Psychological Health But Doesn’t Appear to be Feasible and Acceptable.

 

By John M. de Castro, Ph.D.

 

“Slammed by long and unpredictable hours, heavy clinical workloads, fatigue and limited professional control, many medical residents experience stress and even burnout. And surveys indicate this burnout can seriously impact physician well-being and patient care outcomes.” – Jennifer Huber

 

Stress is epidemic in the western workplace with almost two thirds of workers reporting high levels of stress at work. In high stress occupations, like healthcare, burnout is all too prevalent. Burnout is the fatigue, cynicism, emotional exhaustion, sleep disruption, and professional inefficacy that comes with work-related stress. It is estimated that over 45% of healthcare workers experience burnout. It not only affects the healthcare providers personally, but also the patients, as it produces a loss of empathy and compassion. Burnout, in fact, it is a threat to the entire healthcare system. Currently, over a third of healthcare workers report that they are looking for a new job. Hence, burnout contributes to the shortage of doctors and nurses.

 

Preventing burnout has to be a priority. Unfortunately, it is beyond the ability of the individual to change the environment to reduce stress and prevent burnout. So, it is important that methods be found to reduce the individual’s responses to stress; to make the individual more resilient when high levels of stress occur. Contemplative practices have been shown to reduce the psychological and physiological responses to stress and improve well-being. Indeed, mindfulness has been shown to be helpful in treating and preventing burnout, increasing resilience, and improving sleep. Yoga is a mind-body practice that includes mindfulness and exercise. Yoga practice has been shown to improve the symptoms of burnout. But it is unclear whether it would be feasible and effective for resident physicians.

 

In today’s Research News article “Evaluation of a Yoga-Based Mind-Body Intervention for Resident Physicians: A Randomized Clinical Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7961714/ ) Loewenthal and colleagues recruited resident physicians and randomly assigned them to a wait-list control condition or to receive 1-hour, once a week for 6-weeks yoga training with daily home practice. They completed a questionnaire regarding the feasibility of the program. They were also measured before and after training and 2-months later for psychological health, including mindfulness, resilience, perceived stress, professional fulfillment, depression, anxiety, sleep disturbance, and resident well-being.

 

The participants rated the feasibility and acceptability of the program as low and they averaged attending only 1.93 of the 6 sessions with no one completing all 6 sessions. They found that the yoga group had significant increases in mindfulness, resilience, professional fulfillment, and resident well-being and significant decreases in anxiety, perceived stress, and sleep disturbance. While the wait-list group did not.

 

These efficacy findings are similar to those reported in other studies that yoga training results in increases in mindfulness, resilience, and well-being and significant decreases in anxiety, perceived stress, and sleep disturbance. But the program was very disappointing in feasibility and acceptability. Resident physicians are pressed for time and stressed and may not have the time too attend classes and practice yoga. Other mindfulness programs, particularly those implemented online have been found to be feasible, acceptable, and effective for health care workers. They would appear to be preferable to yoga for resident physicians.

 

So, yoga improves resident physician psychological health but doesn’t appear to be feasible and acceptable.

 

“So often we treat others’ bodies and minds, yet often neglect our own. While we encourage our patients to roll out their mats and settle into their asanas, we can remember to do it ourselves. When we treat our stress and anxiety, we will be better able to treat our patients.” – Julia Michie Bruckner,

Abstract

Background and Objective

Mind-body interventions (MBIs) have been shown to be effective individual-level interventions for mitigating physician burnout, but there are no controlled studies of yoga-based MBIs in resident physicians. We assessed the feasibility of a yoga-based MBI called RISE (resilience, integration, self-awareness, engagement) for residents among multiple specialties and academic medical centers.

Methods

We conducted a waitlist controlled randomized clinical trial of the RISE program with residents from multiple specialty departments at three academic medical centers. The RISE program consisted of six weekly sessions with suggested home practice. Feasibility was assessed across six domains: demand, implementation, practicality, acceptability, adaptation, and integration. Self-reported measures of psychological health were collected at baseline, post-program, and two-month follow-up.

Results

Among 2,000 residents contacted, 75 were assessed for eligibility and 56 were enrolled. Forty-four participants completed the study and were included in analysis. On average, participants attended two of six sessions. Feasibility of in-person attendance was rated as 28.9 (SD 25.6) on a 100-point visual analogue scale. Participants rated feasibility as 69.2 (SD 26.0) if the program was offered virtually. Those who received RISE reported improvements in mindfulness, stress, burnout, and physician well-being from baseline to post-program, which were sustained at two-month follow-up.

Conclusion

This is the first controlled study of a yoga-based MBI in residents. While the program was not feasible as delivered in this pilot study, initial analyses showed improvement in multiple measures of psychological health. Residents reported that virtual delivery would increase feasibility.

Improve Hypertension with Mindfulness Training

 

By John M. de Castro, Ph.D.

 

“Several practices that help calm the mind can also lower blood pressure. All are types of meditation, which use different methods to reach a state sometimes described as “thoughtful awareness” or “restful alertness.” – Harvard Health

 

High Blood Pressure (Hypertension) is an insidious disease because there are no overt symptoms. The individual feels fine. But it can be deadly as more than 360,000 American deaths, roughly 1,000 deaths each day, had high blood pressure as a primary or contributing cause. In addition, hypertension markedly increases the risk heart attack, stroke, heart failure, and kidney disease.  It is also a very common disorder with about 70 million American adults (29%) having high blood pressure and only about half (52%) of people with high blood pressure have their condition under control. Treatment frequently includes antihypertensive drugs. But these medications often have adverse side effects. So, patients feel lousy when taking the drugs, but fine when they’re not. So, compliance is a major issue with many patients not taking the drugs regularly or stopping entirely.

 

Obviously, there is a need for alternatives to drugs for reducing blood pressure. Mindfulness practices have been shown to aid in controlling hypertension. There has accumulated a body of research on the ability of Mindfulness practices to affect hypertension. So, it makes sense to summarize what has been learned.

 

In today’s Research News article “Is Mindfulness-Based Stress Reduction Effective for People with Hypertension? A Systematic Review and Meta-Analysis of 30 Years of Evidence.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8000213/ ) Conversano and colleagues review, summarize and perform a meta-analysis of the published research studies of the effectiveness of mindfulness training on hypertension. They identified 6 published studies that employed either Mindfulness-Based Stress Reduction (MBSR) (3 studies), Mindfulness-Based Cognitive Therapy (MBCT) (2 studies), and mindfulness meditation (1 study).

 

They report that the published research found that mindfulness training improved hypertension with reductions in both systolic and diastolic blood pressure. They further report that mindfulness training worked best when the number of patients taking antihypertensive drugs were low, with the lower the percentage of participants on antihypertensive drugs, the greater the effect size of mindfulness training on hypertension.

 

These are impressive results that suggest that mindfulness training is a safe and effective treatment for hypertension. The trainings appear to work best in the absence of drugs to control hypertension. It follows that mindfulness training would reduce the physical effects of hypertension and thereby improve the overall health and longevity of the patients.

 

So, improve hypertension with mindfulness training.

 

“The hope is that if we can start mindfulness training early in life, we can promote a trajectory of healthy aging across the rest of people’s lives. That will reduce their chances of getting high blood pressure in the first place.” – Eric Loucks

Abstract

Background: Hypertension is among the most important risk factors for cardiovascular diseases, which are considered high mortality risk medical conditions. To date, several studies have reported positive effects of mindfulness-based stress reduction (MBSR) interventions on physical and psychological well-being in other medical conditions, but no meta-analysis on MBSR programs for hypertension has been conducted. Objectives: The objective of this study was to determine the effectiveness of MBSR programs for hypertension. Methods: A systematic review and meta-analysis of randomized controlled trials examining the effects of MBSR on systolic and diastolic blood pressure (BP), anxiety, depression, and perceived stress in people with hypertension or pre-hypertension was conducted. The PubMed/MEDLINE and PsycINFO databases were searched in November 2020 to identify relevant studies. Results: Six studies were included. The comparison of MBSR versus control conditions on diastolic BP was associated with a statistically significant mean effect size favoring MBSR over control conditions (MD = −2.029; 95% confidence interval (CI): −3.676 to −0.383, p = 0.016, k = 6; 22 effect sizes overall), without evidence of heterogeneity (I2 = 0.000%). The comparison of MBSR versus control conditions on systolic BP was associated with a mean effect size which was statistically significant only at a marginal level (MD = −3.894; 95% CI: −7.736–0.053, p = 0.047, k = 6; 22 effect sizes overall), without evidence of high heterogeneity (I2 = 20.772%). The higher the proportion of participants on antihypertensive medications was, the larger the effects of MBSR were on systolic BP (B = −0.750, z = −2.73, p = 0.003). Conclusions: MBSR seems to be a promising intervention, particularly effective on the reduction of diastolic BP. More well-conducted trials are required.

Tai Chi Practice Improves the Symptoms of Multiple Diseases

Tai Chi Practice Improves the Symptoms of Multiple Diseases

 

By John M. de Castro, Ph.D.

 

“In addition to easing balance problems, and possibly other symptoms, tai chi can help ease stress and anxiety and strengthen all parts of the body, with few if any harmful side effects.” Peter Wayne

 

Tai Chi is an ancient mindfulness practice involving slow prescribed movements. It is gentle and completely safe, can be used with 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. Indeed, studies have shown that Tai Chi practice is effective in improving the symptoms of many different diseases. The evidence is accumulating. So, it makes sense to step back and summarize what has been learned about the effectiveness of different Tai Chi practices for different disease conditions.

 

In today’s Research News article “.Clinical Evidence of Tai Chi Exercise Prescriptions: A Systematic Review” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7972853/ ) Huang and colleagues review and summarize the published randomized controlled trials on the effectiveness of different Tai Chi practices for different disease conditions. They identified 139 published randomized controlled trials utilizing a number of different Tai Chi styles and numbers of forms. Yang style was by far the most frequent style and 24 forms was the most frequent number of forms employed.

 

They report that the published research found that Tai Chi practice produced significant improvement in the symptoms of musculoskeletal system or connective tissue diseases such as osteoarthritis, fibromyalgia, and chronic low back pain.; on circulatory system diseases such as hypertension, stroke, coronary heart disease, and chronic heart failure; on mental and behavioral disorders such as depression, cognitive impairment, and intellectual disabilities; on nervous system diseases such as Parkinson’s disease, dementia, and sleep disorders; on chronic obstructive pulmonary disease (COPD); on endocrine, nutritional, or metabolic diseases such as type 2 diabetes and metabolic syndrome; on the physical and mental state of cancer patients, and on traumatic brain injury and urinary tract disorders; on balance control and flexibility and falls in older adults.

 

These are remarkable findings. Tai Chi practice appears to be a safe and effective treatment for the symptoms of a wide variety of diseases. It doesn’t cure the disease. Rather if alleviates the symptoms. It is not known the mechanisms by which Tai Chi has these benefits. Future research needs to further explore what facets or effects of Tai Chi practice are responsible for the disease symptom improvements.

 

So, Tai Chi practice improves the symptoms of multiple diseases.

Abstract

Objectives

This systematic review aims to summarize the existing literature on Tai Chi randomized controlled trials (RCTs) and recommend Tai Chi exercise prescriptions for different diseases and populations.

Methods

A systematic search for Tai Chi RCTs was conducted in five electronic databases (PubMed, Cochrane Library, EMBASE, EBSCO, and Web of Science) from their inception to December 2019. SPSS 20.0 software and Microsoft Excel 2019 were used to analyze the data, and the risk of bias tool in the RevMan 5.3.5 software was used to evaluate the methodological quality of RCTs.

Results

A total of 139 articles were identified, including diseased populations (95, 68.3%) and healthy populations (44, 31.7%). The diseased populations included the following 10 disease types: musculoskeletal system or connective tissue diseases (34.7%), circulatory system diseases (23.2%), mental and behavioral disorders (12.6%), nervous system diseases (11.6%), respiratory system diseases (6.3%), endocrine, nutritional or metabolic diseases (5.3%), neoplasms (3.2%), injury, poisoning and certain other consequences of external causes (1.1%), genitourinary system diseases (1.1%), and diseases of the eye and adnexa (1.1%). Tai Chi exercise prescription was generally classified as moderate intensity. The most commonly applied Tai Chi style was Yang style (92, 66.2%), and the most frequently specified Tai Chi form was simplified 24-form Tai Chi (43, 30.9%). 12 weeks and 24 weeks, 2-3 times a week, and 60 min each time was the most commonly used cycle, frequency, and time of exercise in Tai Chi exercise prescriptions.

Conclusions

We recommend the more commonly used Tai Chi exercise prescriptions for different diseases and populations based on clinical evidence of Tai Chi. Further clinical research on Tai Chi should be combined with principles of exercise prescription to conduct large-sample epidemiological studies and long-term prospective follow-up studies to provide more substantive clinical evidence for Tai Chi exercise prescriptions.

Improve the Brains Ability to Directly Control Computers with Mindfulness

Improve the Brains Ability to Directly Control Computers with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Meditation has been widely practiced for well-being and improving health,” said He. Our work demonstrates that it can also enhance a person’s mental power for mind control, and may facilitate broad use of noninvasive brain-computer interface technology.” – Bin He

 

It has long been a dream to develop methods to allow the brain to directly alter external devices. The efforts have been focused on developing a brain-computer interface such that recorded electrical activity of the brain is interfaced with a computer allowing control of the computer by the activity. It is hypothesized that a brain computer interface might be able to provide an alternative method to control muscles in patients with severe neuromuscular diseases.

 

Brain-computer interface methods have been developed but suffer from long training times before the participant is capable of affecting the computer activity. Meditation has been shown to alter the activity of the brain. Meditation training may make the individual better at controlling their brain activity. Hence, an interesting research question is to investigate whether meditation training will improve the ability to learn to control a computer with the brain’s electrical activity.

 

In today’s Research News article “Frontolimbic alpha activity tracks intentional rest BCI control improvement through mindfulness meditation.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7994299/ ) Jiang and colleagues recruited healthy adults without brain-computer interface experience and randomly assigned them to a wait-list control condition or to receive 8 weeks of Mindfulness-Based Stress Reduction (MBSR) program. After training they all participated in 6 or 10 weekly, 1-hour, brain-computer interface training sessions. Their brain electrical activity was recorded with an electroencephalogram (EEG). The electrical activity occurring in the motor cortex was connected to a computer which moved a cursor over the screen. The participants were asked to try to move the cursor left or right by imagining opening and closing the left or right hand, to move the cursor up by imagining opening and closing both hands and down by resting.

 

They found that compared to the wait-list control group the Mindfulness-Based Stress Reduction (MBSR) group had significantly greater improvement in the brain-computer interface task over sessions. They also found that the MBSR group had significantly greater alpha rhythm (8-12 hz. in the EEG) power in the frontal and limbic regions of the brain. They also found that over training there was decreased frontolimbic connectivity in the MBSR group while the wait-list control group had greater connectivity. Finally, the greater the increase in alpha rhythm power in the MBSR group, the greater the increase in the brain-computer interface task performance over sessions.

 

These results suggest that mindfulness training improves the individual’s ability to learn to control a computer with brain activity. Underlying this improved performance appears to be changes in the electrical activity of the brain at rest and during task performance. Mindfulness training is known to improve attention and reduce mind wandering. This may be how mindfulness training improves the individual’s ability to learn to control the computer with brain activity. It remains for future research to investigate this possibility.

 

So, improve the brains ability to directly control computers with mindfulness.

 

“the emphasis on present-moment experience may allow expert meditators to self-regulate brain activity which could translate into enhanced [Brain-Computer Interface] control. Self-regulation supported by attentional control, emotional control, and self-awareness may additionally help users aim at a state of effortless relaxation, which has been hypothesized to improve [Brain-Computer Interface] control.” – James R. Stieger

Abstract

Brain–computer interfaces (BCIs) are capable of translating human intentions into signals controlling an external device to assist patients with severe neuromuscular disorders. Prior work has demonstrated that participants with mindfulness meditation experience evince improved BCI performance, but the underlying neural mechanisms remain unclear. Here, we conducted a large-scale longitudinal intervention study by training participants in mindfulness-based stress reduction (MBSR; a standardized mind–body awareness training intervention), and investigated whether and how short-term MBSR affected sensorimotor rhythm (SMR)-based BCI performance. We hypothesize that MBSR training improves BCI performance by reducing mind wandering and enhancing self-awareness during the intentional rest BCI control, which would mainly be reflected by modulations of default-mode network and limbic network activity. We found that MBSR training significantly improved BCI performance compared to controls and these behavioral enhancements were accompanied by increased frontolimbic alpha activity (9–15 Hz) and decreased alpha connectivity among limbic network, frontoparietal network, and default-mode network. Furthermore, the modulations of frontolimbic alpha activity were positively correlated with the duration of meditation experience and the extent of BCI performance improvement. Overall, these data suggest that mindfulness allows participant to reach a state where they can modulate frontolimbic alpha power and improve BCI performance for SMR-based BCI control.
