“Regular meditators activated fewer brain regions than non-meditators in order to achieve the same performance during an attentional task. This is evidence that meditation training can increase brain efficiency in attention and impulse control.” – Elisa Kozasa

 

One of the primary effects of meditation training is an improvement in the ability to pay attention to the task at hand and ignore interfering stimuli. This is an important consequence of meditation training and produces improvements in thinking, reasoning, and creativity. These improvements are known to occur due to the effects of meditation training on the brain. It appears That meditation increases the size, connectivity, and activity of areas of the brain that are involved in paying attention.

 

A common method to study the activity of the nervous system is to measure the electrical signal at the scalp above brain regions. Changes in this activity are measurable with mindfulness training. One method to observe information processing in the brain is to measure the changes in the electrical activity that occur in response to specific stimuli. These are called evoked potentials or ERPs. The signal following a stimulus changes over time. The fluctuations of the signal after specific periods of time are thought to measure different aspects of the nervous system’s processing of the stimulus.

 

The P3 response in the evoked potential (ERP) occurs around a quarter of a second following the stimulus presentation. It is a positive change that is maximally measured over the central frontal lobe. The P3 response has been associated with the engagement of attention. So, the P3 response is often used as a measure of brain attentional processing with the larger the positive change the greater the attentional focus. The N2 response in the evoked potential (ERP) generally precedes the P3 response. It is a negative change that is maximally measured over the frontal lobe. The N2 response has been associated with the engagement of attention to a new or novel stimulus. So, the N2 response is often used as a measure of brain attentional processing with the large the negative changes an indication of greater discrimination of new stimuli.

 

In today’s Research News article “Event-related potential correlates of mindfulness meditation competence”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1181052878585303/?type=3&theater

Atchley and colleagues measure the P3 and N2 responses in naive, novice (less than 1000 hours of experience), or experienced (more than 5000 hours of experience) meditators in an attempt to measure the effects of amount of meditation practice on brain function. The participants listened to a series of tones. ERPs were measured under two conditions. In the first condition they were asked to push a button whenever and infrequent high-pitched tome occurred. In the second condition they meditated by counting breaths and were asked to ignore the tones.

 

They found that all groups had lower P3 responses in the breath counting condition, but both groups of meditators had greater reductions in the response than the naïve participants. This suggested that meditation training improves the ability to screen out distracting or irrelevant stimuli. Meditators also had a greater reduction in N2 amplitude than the naïve group in the breath counting condition. This suggests that meditation training improves the ability to react less to new stimuli and thereby have an improved ability to ignore new stimuli and not react to novelty.

 

It is interesting that no differences were found between novice and experienced meditators. But, their definition of a novice meditator as having less than 1000 hours of experience may actually have produced a group of fairly experienced meditators as the novice group averaged 2.4 years of meditation experience. Perhaps with a less experienced group, differences with experienced meditators may have been seen.

 

Regardless, the results demonstrate that meditation reshapes the brain to improve the ability to pay attention to the task at hand and ignore irrelevant and/or distracting information. So, shape the brain to improve attention with meditation.

 

“To cultivate attention, it is sufficient to rely on one basic principle: return again and again to what is already there. Our body knows how to sit straight. Our breath knows how to flow naturally. Our mind and our hearts already know how to rest. In this practice, we simply allow them to do that. Whenever there is a disturbance, we return to what is already there.” – Ken McLeod

Just Breathe

“When the breath wanders the mind also is unsteady. But when the breath is calmed the mind too will be still, and the yogi achieves long life. Therefore, one should learn to control the breath.” ~Svatmarama

 

There are two basic forms of meditation, focused meditation and open monitoring. For the beginner, most teachers employ the focused meditation strategy. This involves placing attention on a single object of meditation and holding it there. Focusing on the breath is the most common object for focused meditation. But, there are many others including single thoughts or mental objects, or even mantras.

 

Although there has been research comparing focused to open monitoring meditation, there has been very little attention paid to different objects of focused meditation. The question has not been answered as to whether it is better to focus on the breath or some other mental object. The whole idea of focusing on an object is to eliminate wind wandering. So one way to compare the effectiveness of different objects for focused meditation is by comparing their relative abilities to prevent mind wandering or conversely to suppress thoughts.

 

In today’s Research News article “Better control with less effort: The advantage of using focused-breathing strategy over focused-distraction strategy on thought suppression”

Ju and colleagues randomly assigned undergraduate students to a focused breathing condition or a focused mental object (blue sports car) condition. Students were instructed to focus on their respective object for 2 3-minute sessions and report each time their mind wandered. The students were then measured for thought intrusions during a thought suppression task. They found that the focused breathing condition produced significantly fewer mind wanderings and thought intrusions than the focused mental object condition. For the focused mental object condition, the higher the participants working memory capacity the fewer mind wanderings and thought intrusions. This was not true for the focused breathing condition. This suggests that focusing on a mental object requires mental resources and employs a ‘top down’ strategy while simply focusing on the breath does not.

 

So, it appears that focusing on the breath requires less mental resources and is more successful in preventing mind wandering and thought intrusions than focusing on a mental object. This suggests that the ancient practice of focused breathing meditation became so popular for a reason. It is easier to do and it produces better results.

 

It should be kept in mind, however, that the students were only asked to focus for 2 3-minute periods. It is possible that the superiority of focusing on the breathing may only be true for beginners over very brief periods. There is a need to repeat the study with experienced meditators and for longer periods of focus. Nevertheless, it has become common practice with open monitoring meditation to always begin a session with focusing on the breath and only later moving into open monitoring. The current results suggest that this may be very good practice, helping to get the meditator focused, with minimal mind wandering before moving on to open monitoring where it is more difficult to maintain focus and keep the mind from wandering.

 

So, just breathe to better focus in meditation.

 

“So don’t beat yourself up the next time you find yourself far away from where your mind was supposed to be. It’s the nature of the mind to wander. Use it as an opportunity to become more aware of your own mental experience. But you may still want to return to the present moment—so you can come up with an answer to that question everyone is waiting for.” – Wendy Hasenkamp

Meditate to Improve Attention by Changing the Brain

psyjdc Leave a comment

 

“meditation may increase our control over our limited brain resources. To anyone who knows what it’s like to feel scattered or overwhelmed, this is an appealing benefit indeed. Even though your attention is a limited resource, you can learn to do more with the mental energy you already have.” – Kelly McGonigal

 

Meditation practice has many psychological, cognitive, and physical benefits. It has been shown to improve attentional abilities so that we can better maintain our attention when needed and reduce the strong human tendency for mind wandering (see http://contemplative-studies.org/wp/index.php/category/research-news/attention/), the enemy of focused attention. This allows us to better attend to the present moment, what’s happening now, rather than be dominated by thought, memories, and plans for the future.

 

In the last few decades, scientists have discovered that the brain is far more malleable than previously thought. Areas in the brain can change, either increase or decrease in size, connectivity, and activity in response to changes in our environment or the behaviors we engage in. This process is referred to as neuroplasticity. Alterations in the brain can be produced by contemplative practices. The brain appears to change in response to meditation and other contemplative practices. Indeed, mindfulness practices have been shown to not only alter how we think and feel but also to alter the nervous system (see http://contemplative-studies.org/wp/index.php/category/research-news/neuroplasticity/).

 

In today’s Research News article “Increases in the right dorsolateral prefrontal cortex and decreases the rostral prefrontal cortex activation after-8 weeks of focused attention based mindfulness meditation”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1155321364491788/?type=3&theater

Tomasino and colleagues investigate neuroplastic changes to the brain when individuals who have no experience with meditation engage in an 8-week meditation program. The participants’ brain activity during meditation was measured with functional magnetic resonance imaging (f-MRI) before and after the meditation training. They found that at the end of training the participants showed greater activation of the right middle frontal gyrus and the left caudate/anterior insular cortex. They also found that the practice decreased activation in the rostral prefrontal cortex and in right parietal cortex. They further demonstrated that these altered brain activities were produced by the focused meditation component and not a body scan component of the practice.

 

The increased activity observed in the prefrontal areas makes perfect sense as meditation is an attentional practice and the prefrontal areas have been previously shown to be associated with attention. So, practicing attention alters the brain areas responsible for attention. The decreased activity observed in the rostral prefrontal cortex also makes perfect sense as focused attention is antithetical to mind wandering and the rostral prefrontal cortex has been shown to be involved in the “default mode network” that is activated during mind wandering. So, practicing attention also decreases activity in the brain areas responsible for its opposite, mind wandering. So, meditation practice was found to strengthen the activity of the exact areas of the brain that are known to be increased by attentional activity and reduced activity of the areas known to be increased during mind wandering.

 

Hence, meditation practice by naive individuals appears to alter their brains to better maintain attention and restrain mind wandering. The fact that the brain has been changes suggests that the improved attentional ability will be maintained even when the individuals are not actively meditating. This make the practice far more useful as it has more long-lasting effects.

 

So, meditate to improve attention by changing the brain.

 

“Meditation provides experiences that the mind can achieve no other way, such as inner silence and expanded awareness. And as the mind gains experience, the brain shows physical activity as well—sometimes profound changes. . . . the research has begun to show that meditation can also produce long-term structural changes in the brain. No longer is the “hard wiring” of neural circuits so dominant. The brain can alter its wiring in “soft” ways, thanks to a trait known as neuroplasticity, which allows new pathways and even new brain cells to appear.” – Deepak Chopra

Improve High Level Thinking with Mindfulness

psyjdc 13 Comments

 

“Take the attitude of a student, never be too big to ask questions, never know too much to learn something new.” – Og Mandino

 

In the modern world education is a key for success. Where a high school education was sufficient in previous generations, a college degree is now required to succeed in the new knowledge based economies. There is a lot of pressure on students to excel so that they can be admitted to the best universities and there is a lot of pressure on university students to excel so that they can get the best jobs after graduation. As a result, parents and students are constantly looking for ways to improve student performance in school.

 

The primary tactic has been to pressure the student and clear away routine tasks and chores so that the student can focus on their studies. But, this might in fact be counterproductive as the increased pressure can actually lead to stress and anxiety which can impede performance. A better tactic may be the development of mindfulness skills with contemplative practices. These practices and high levels of mindfulness have been shown to be helpful in coping with the school environment and for the performance of both students and teachers (see http://contemplative-studies.org/wp/index.php/category/research-news/school/). So, perhaps, mindfulness training may provide the needed edge in school.

 

In today’s Research News article “Effects of a Mindfulness Meditation Course on Learning and Cognitive Performance among University Students in Taiwan”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1151653591525232/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4657094/

Ching and colleagues took advantage of the natural experiment provided in a private university which required a semester long mindfulness course as a core course for all students. The course taught meditation, body scan, and everyday mindfulness skills. They compared students who completed the course in the fall semester to those who were scheduled to take the course in the spring semester. They measured the students with the College Learning Effectiveness Inventory (CLEI) which measures psychosocial factors including thoughts, feelings, or behaviors related to academic outcomes and also measured performance on the cognitive tasks of vigilance, choice reaction times, spatial working memory, and memory scanning.

 

The study demonstrated that the mindfulness training produced significantly higher scores on the CLEI suggesting improved attitudes and behaviors impacting learning and academic performance. In addition, the mindfulness training produced improved performance on the cognitive tasks, including increased accuracy in the vigilance, choice reaction time, and spatial working memory tasks. These results suggest that mindfulness training can improve cognitive performance in college students and improve their psychosocial attitudes toward and adjustment to college life. Although actual grade performance was not investigated, the improved skills would predict better academic performance.

 

There are a number of known effects of mindfulness practice that could be responsible for the improved cognitive and psychosocial skills in the college students. Mindfulness training has been shown to directly affect cognitive skills (see http://contemplative-studies.org/wp/index.php/category/research-news/cognition/), social skills (see http://contemplative-studies.org/wp/index.php/category/research-news/social-behavior/), and psychological well-being (see   http://contemplative-studies.org/wp/index.php/category/research-news/well-being/). In addition, mindfulness training is known to reduce the physiological and psychological responses to stress (see http://contemplative-studies.org/wp/index.php/category/research-news/stress/) which may reduce the anxiety produced by the pressures of college. Finally, mindfulness training is known to improve sleep (see http://contemplative-studies.org/wp/index.php/category/research-news/sleep/) which is known to be a problem for college students. So, it appears clear that mindfulness training has many desired effects that promote school performance and thus mindfulness training should be considered for incorporation in school curricula.

 

So, improve high level thinking with mindfulness.

Mindfully Improve Thinking after Recovery from Cancer

psyjdc 4 Comments

 

“You can be a victim of cancer, or a survivor of cancer. It’s a mindset.” – Dave Pelzer

 

Cancer diagnosis is not a death sentence. Over half of the people diagnosed with cancer are still alive 10 years later and this number is rapidly improving. With breast cancer about 80% survive at least 5 years and the earlier the diagnosis the better the survival rate. With colorectal cancer about 50% survive at least 5 years and again the earlier the diagnosis the better the survival rate.  It is estimated that 14,483,830 adults and children with a history of cancer alive in the United States today. So, there are a vast number of cancer survivors.

 

Surviving cancer carries with it a number of problems. “Physical, emotional, and financial hardships often persist for years after diagnosis and treatment. Cancer survivors are also at greater risk for developing second cancers and other health conditions.” National Cancer Survivors Day. Unfortunately, most of these residual problems go untreated. Psychologically, cancer survivors frequently suffer from anxiety, depression, mood disturbance, Post-Traumatic Stress Disorder (PTSD), sleep disturbance, fatigue, sexual dysfunction, loss of personal control, impaired quality of life, and psychiatric symptoms which have been found to persist even ten years after remission.

 

Less well known is that cancer survivors frequently suffer from residual cognitive impairments that affect the majority of survivors and can last for many years. These include problems with attention, including divided attention and multitasking, memory, including short and long-term memory and retrieval, and executive function. These impairments in the ability to think and the extra energy needed for routine cognitive activities can increase fatigue over the day.

 

Mindfulness has been shown to help with cancer recovery and help to alleviate many of the residual psychological symptoms (see http://contemplative-studies.org/wp/index.php/category/research-news/cancer/) and it has been shown to improve cognitive function (see http://contemplative-studies.org/wp/index.php/category/research-news/cognition/).  So, it would seem reasonable to postulate that mindfulness might help in alleviating the cognitive impairments occurring in cancer survivors.

 

In today’s Research News article “Randomized controlled pilot trial of mindfulness-based stress reduction for breast and colorectal cancer survivors: effects on cancer-related cognitive impairment”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1142698709087387/?type=3&theater

Johns and colleagues examined the effect of an 8-week Mindfulness-based stress reduction (MBSR) program on cognitive function in cancer survivors and compared it to an 8-week Education and Support (ES) program involving comparable amounts of time. They found that the MBSR group in comparison to the ES group showed greater improvements in overall attentional function, particularly with effective action and attentional lapses. The MBSR group also showed greater improvement in ability to cope with cognitive interference as measured by the classic Stroop test. These improvements were lasting as they were still present 6-months after the conclusion of treatment.

 

These are exciting results as they are in comparison to an active control condition and they suggest that MBSR is an effective treatment for the cognitive impairments in cancer recovery patients. There are a number of explanations for how MBSR might produce these improvements. MBSR targets stress and has been shown to effectively reduce psychological and physiological stress responses. This stress reduction could greatly help the survivors deal with their residual problems. MBSR also markedly improves attention, particularly present moment attention. This may fairly directly help improve cognitive function. MBSR also improves emotion regulation. This may make the survivors better able to cope with the emotional sequela of cancer recovery. Finally, MBSR has been shown to improve cognitive function in healthy individuals and may simply be improving overall cognitive function and not specifically treating the cognitive symptoms of cancer recovery.

 

Regardless of the explanation, it is clear that mindfulness training is effective in alleviating the cognitive problems following recovery from cancer.

 

So, improve thinking after recovery from cancer with mindfulness.

Meditate Effortlessly with Practice.

psyjdc Leave a comment

 

“Watch your thoughts as you watch the street traffic. People come and go; you register without response. It may not be easy in the beginning, but with some practice you will find that your mind can function on many levels at the same time and you can be aware of them all.” – Nisargadatta Maharaj

 

When a meditation practice is first begun, this simple activity can seem devilishly difficult; requiring a great deal of effort to be expended to maintain focus. Yet the effort doesn’t seem to make it any easier. Rather, it seems to get more and more difficult to keep the mind from wandering away. This is an important lesson unto itself. It becomes clear that the mind is not under the control that was imagined. In fact, the mind appears to be an unruly beast that is extraordinarily difficult to tame. That is why many teachers refer to it as the monkey mind. This revelation is often startling to the beginner and is itself a great insight.

 

Over time, however, without really understanding how, meditation gets more and more focused with less and less effort. That’s not to say that the mind doesn’t wander, it does and frequently. But, it does so less often for shorter periods of time and the mind wandering doesn’t evoke the same anger and frustration that it used to. The whole process becomes much more relaxing. The focus of meditation doesn’t seem to require the level of effort that it once did. Relaxed enjoyment of just being becomes more frequent and enduring as the meditator stops fighting the mind and instead becomes an awake detached observer.

 

What changes with practice? How does meditation become so much easier and relaxed? One possibility is that as practice develops, it changes the brain. Indeed, contemplative practice is known to produce alterations in the structure, connectivity, and activity of brain areas (see http://contemplative-studies.org/wp/index.php/category/research-news/neuroplasticity/ and http://contemplative-studies.org/wp/index.php/category/research-news/brain-electrical-activity/). These changes occur in a number of neural areas and systems. But, the changes frequently involve the frontal lobes (see http://contemplative-studies.org/wp/?s=frontal). This is particularly important as the frontal lobes are thought to be very important for high level cognitive processes sometimes labelled as executive function. Among these frontal lobe functions is attentional ability. It is important to focusing and maintaining attention.

 

In today’s Research News article “Effortless Attention as a Biomarker for Experienced Mindfulness Practitioners”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1141006622589929/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4601770/

Tanaka and colleagues investigated the electrical activity of the frontal lobes during a 40 minute session of open monitoring meditation (see http://contemplative-studies.org/wp/index.php/2015/07/25/beginning-meditation-getting-started-4-open-monitoring-meditation/). They recorded Beta band frequencies (13-30 hertz) of frontal EEG activity and compared it between first time meditators and long-term experienced meditators with over 5 years of consistent meditation practice. The Beta band was selected as it has been shown to be associated with attention, vigilance and processing information.

 

The power of Beta band activity did not differ between groups during the rest period prior to meditation. During meditation Beta band power was significantly higher for the first time meditators than the experienced meditators. Since increased power in the Beta band is associated with attention, the observations suggest that the first time meditators are investing more effort into maintaining attention while the experienced meditators are using minimal effort to maintain attention. These results are in line with what is reported to occur in long-term meditators with maintaining attention described as effortless. These results also suggest the possibility that changes in the frontal lobe may underlie the effortless effort of experienced meditators.

 

So, regularly practice meditation letting it become effortless.

Improve Mental and Physical Well-being with Yoga

Yoga cognition Nagendra2

“The breathing and meditative exercises aim at calming the mind and body and keeping distracting thoughts away while you focus on your body, posture or breath. Maybe these processes translate beyond yoga practice when you try to perform mental tasks or day-to-day activities.” – Neha Gothe

 

If we are lucky enough to navigate life’s dangers we are rewarded with the opportunity to experience aging! The aging process involves a progressive deterioration of the body including the brain. It actually begins in the late 20s and continues throughout the lifespan. It’s inevitable. We can’t stop it or reverse it. But, it is becoming more apparent that life-style changes can slow down and to some extent counteract the process and allow us to live longer and healthier lives. This is true for both physical and mental deterioration including degeneration and shrinkage of the nervous system. Aging healthily to a large extent involves strategies to slow down the deterioration.

 

Contemplative practices including yoga practice (See links below) have been shown to reduce the physical deterioration that occurs with aging (see http://contemplative-studies.org/wp/index.php/category/research-news/aging/). Yoga practice has many physical and mental benefits including protection of brain structures from degeneration with aging (see http://contemplative-studies.org/wp/index.php/2015/07/17/age-healthily-protect-the-brain-with-yoga/). These structural changes have been demonstrated by neuroimaging techniques with yoga practitioners. They document change in the size and connectivity of brain structures that result from yoga practice.

 

Yoga is a mind-body practice that involves both physical and mental exercises. This is accompanied by changes in the activity of virtually every component of the body including general physiology and the peripheral and central nervous systems. So, another potential method to investigate yoga’s effects on the nervous system is to measure the electrical signals emanating from the nervous system.

 

In today’s Research News article “Cognitive Behavior Evaluation Based on Physiological Parameters among Young Healthy Subjects with Yoga as Intervention”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1136173913073200/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4339827/

Nagendra and colleagues trained naive adults in yoga practice for a period of five months for 1.5 hours per day and compared physiological measure to a no-treatment control group. They found that yoga practice produced an increase in parasympathetic (vegetative) and decrease in sympathetic (activation) activity in the peripheral nervous system including a decrease in heart rate and heart rate variability. This indicates a calming and relaxing effect of yoga on the physiology.

 

Nagendra and colleagues also found significant differences in EEG activity of the central nervous system. The changes were complex and varied. But they are indicators that yoga practice produces alterations of brain activity in ways that are indicative of improved vigilance, alertness, attention, concentration ,memory, visual information processing, sense of wellbeing, responsiveness, emotion process, cognition, and executive function and reduced stress and strain. In other words the changes in the brain activity indicated vast improvements in mental processing produced by yoga practice.

 

It should be noted that these are indirect measures and the researchers did not directly measure the psychological variables. So, although suggestive they are not conclusive. They are, however, similar to findings of yoga effects in other research with direct measures (see http://contemplative-studies.org/wp/index.php/category/contemplative-practice/yoga-contemplative-practice/). But, even with this caution, the results suggest that yoga practice has widespread beneficial effects on the mental and physical well-being of the individual.

 

So, practice yoga and improve mental and physical well-being.

 

“True yoga is not about the shape of your body, but the shape of your life. Yoga is not to be performed; yoga is to be lived. Yoga doesn’t care about what you have been; yoga cares about the person you are becoming. Yoga is designed for a vast and profound purpose, and for it to be truly called yoga, its essence must be embodied.” — Aadil Palkhivala

Stay Mentally Fit as you Age with Tai Chi

“What helps with aging is serious cognition – thinking and understanding. You have to truly grasp that everybody ages. Everybody dies. There is no turning back the clock. So the question in life becomes: What are you going to do while you’re here?” – Goldie Hawn

 

Aging inevitably involves declining physical and mental ability. Starting in the late twenties the body, including the brain begins a process of slow deterioration. There is no known treatment to prevent this decline. There are, however, things that can be done to slow the progression. For example, a healthy diet and a regular program of exercise can slow the physical decline of the body with aging.

 

Our mental abilities may also decline with age including impairments in memory, attention, and problem solving ability. In sum these are called age related cognitive decline. This occurs to everyone as they age, but to varying degrees. Some deteriorate into a dementia, while others maintain high levels of cognitive capacity into very advanced ages. It is estimated that around 30% of the elderly show significant age related cognitive decline. But, remember that this also means that 70% of the elderly retain reasonable levels of cognitive ability.

 

There are some indications that physical and mental exercise can reduce the rate of cognitive decline and lower the chances of dementia. Tai Chi is an ancient eastern practice involving slow mindful movements. It is both a gentle exercise and a contemplative practice that improves mindfulness. Mindfulness practices have been shown to improve cognitive processes (see http://contemplative-studies.org/wp/index.php/category/research-news/cognition/) while Tai Chi or Qigong practice has been shown to be beneficial for healthy aging (see links below). It would seem reasonable to hypothesize that Tai Chi practice might decrease age related cognitive decline.

 

In today’s Research News article “The Impact of Tai Chi on Cognitive Performance in Older Adults: A Systematic Review and Meta-Analysis”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1121070961250162/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4055508/?report=classic

Wayne and colleagues review the published research on the application of Tai Chi to reduce age related cognitive decline in both elderly individuals who have already demonstrated cognitive decline and those who have not. They found that Tai Chi practice significantly reduced declines in executive function, including working memory, reasoning, task flexibility, problem solving and planning and execution. Tai Chi practice was also found to reduce declines in overall global cognitive function, including learning and memory, mathematical ability and semantic fluency. In addition, these improvements related to Tai Chi practice occurred in both individuals who had already experienced cognitive decline and those who had not. Importantly, these benefits were provided without any significant adverse side effects.

 

Wayne and colleagues hypothesize that Tai Chi may be having its positive effects on cognition through a number of mechanisms. These include the exercise provided by the practice with associated improvements in agility and mobility, the learning of a new skill, the required attentional focus, shifting, and multi-tasking, the mindfulness practice, and the social context of Tai Chi. Any and all of these process involved in Tai Chi practice may be responsible for its cognitive benefits.

 

Regardless of the mechanism, it appears that Tai Chi is a safe and effective practice that reduces the rate of age related cognitive decline whether or not decline was already present. These are exciting findings as Tai Chi has been shown to have many physical benefits for the elderly (see links below). The fact that it also has cognitive benefits makes it an even better choice for practice by the elderly.

 

So practice Tai Chi and stay mentally fit as you age.

Mindfulness Effects on Cognitive Function

 

Improve Diabetes Psychological Well-Being with Mindfulness

“I am a type-2 diabetic, and they took me off medication simply because I ate right and exercised. Diabetes is not like a cancer, where you go in for chemo and radiation. You can change a lot through a basic changing of habits.” – Sherri Shepherd

 

It is estimated that 30 million people in the United States have diabetes and the numbers are growing. Diabetes is the 7th leading cause of death in the United States. In addition, diabetes is heavily associated with other diseases such as cardiovascular disease, heart attacks, stroke, blindness, kidney disease, and circulatory problems leading to amputations. As a result, diabetes doubles the risk of death of any cause compared to individuals of the same age without diabetes.

 

Depression affects people with diabetes more often than people without it — up to 15 percent compared with 6.7 percent in the general population. When depression occurs along with a chronic illness like diabetes, the symptoms tend to be more severe. Compounding the problem further, the symptoms can become worse as depression can lead to missing medication doses, overeating, or skipping exercise. This may mean poorer blood glucose control, which, in turn, means more long-term health complications.

 

So, in treating diabetes it is important to treat not only the physical problem but also the psychological problems such as depression. Mindfulness training, especially Mindfulness-Based Cognitive Therapy Mindfulness-Based Cognitive Therapy (MBCT) has been demonstrated to be effective in treating depression (see http://contemplative-studies.org/wp/index.php/2015/08/15/spiraling-up-with-mindfulness/ and http://contemplative-studies.org/wp/index.php/2015/07/17/dealing-with-major-depression-when-drugs-fail/).

 

In today’s Research News article “Individual Mindfulness-Based Cognitive Therapy for People with Diabetes: a Pilot Randomized Controlled Trial”

Schroevers and colleagues examined whether an individualized version of MBCT might be effective for depression in people with diabetes. In comparison to diabetic patients on a waiting list, MBCT resulted in clinically significant reductions in depressive symptoms and diabetes related psychological distress and increases in the levels of acting with awareness and attention regulation. These improvements were still present three months after completing the program.

 

These are impressive results and suggest that MBCT is an effective treatment for the psychological issues that frequently accompany diabetes. MBCT may be effective due to its emphasis on the present moment in mindfulness. Depression is often rooted in the past and the individual ruminates about the misery of the past. By shifting focus to the present moment, mindfulness can move the individual from being preoccupied with a troubling past to being focused  on addressing the manageable problems in the present. Indeed, Schroevers and colleagues demonstrated that MBCT produces an increase in acting with awareness. The individual then is more aware of what they’re doing. For the depressed diabetic individual this can help in the recognition of how he/she is acting in response to the depression or the diabetes. This allows them to reprogram their responses to be more appropriate to the circumstances of the present rather than responding to the depression itself.

 

Mindfulness also stresses non-judgmental awareness of the present. There is a decreased tendency to be constantly judging what is happening and instead just accept it as what is. This reduces worrying. Indeed, mindfulness practice has been shown to reduce worry (see http://contemplative-studies.org/wp/index.php/2015/07/17/stop-worrying/). Since worry involves concerns about future occurrences to some extent based upon past experiences, the more one can focus on the present the less opportunity there is for worries to arise. Mindfulness training also trains the individual to accept the worry, experience it, and then move on. This reduces the impact of the worry and prevents the development of worrying about worrying.

 

Another possibility is mindfulness’ ability to increase emotion regulation. That is mindfulness assists the individual in recognizing emotions as they arise and not over respond to them. It doesn’t prevent emotions. It simply allows the individual to better deal with them when they do arise. So when depression occurs the individual can recognize it, accept it, and then let it go and not respond to it. This liberates the individual to find new ways of responding to the environment and other people.

 

So, be mindful and improve psychological well-being with diabetes.

Develop a Better Brain Mindfully

The nervous system changes dramatically during development. It is a time when the brain is greatly affected by the environment and experiences of the individual. This is what neuroscientists call neuroplasticity. It is present in adulthood, but is particularly evident and important during development. The nervous system is molded to efficiently analyze the environment presented.

 

Studies of the development of the nervous system during adolescence have revealed marked changes occurring throughout the teen years. The brain doesn’t look like that of an adult until the early 20s. Over the course of childhood the outer layer of the nervous system, the cortex, increases in thickness and then during adolescence thins. Late adolescence is a time of brain development when the highest levels of intellectual development are being produced by refinements in the structures of the nervous system. The thinning of the cortex is thought to reflect a pruning of cortical systems making processing more and more efficient. It is making the nervous system more efficient and tuned to the environment in which it is immersed.

 

It is thought that many of the emotional and behavioral problems during adolescence occur due to the fact that the neural systems underlying emotional reactivity and expression are fully developed well before the development of the higher processes that regulate and control the emotions and the responses to the emotions. As a result, adolescent behavior can be overly determined by emotion. This can potentially explain the high rates of teen suicide, reckless, thrill seeking behavior, and social anxiety. The erratic emotion driven behavior of the teen years is reflected in the teen nervous system.

 

Mindfulness has been shown to be associated with emotion regulation. The higher the level of mindfulness the better able the individual is in experiencing emotions at a manageable level and responding to them adaptively and appropriately (see http://contemplative-studies.org/wp/index.php/2015/09/10/take-command-and-control-of-your-emotions/). Hence, it makes sense to study the development of the brain, mindfulness, and emotion regulation during adolescence. Perhaps mindfulness can compensate for some of the emotional dominance of behavior in the teen.

 

In today’s Research News article “Dispositional mindfulness is predicted by structural development of the insula during late adolescence”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1108203169203608/?type=3&theater

Friedel and colleagues use MRI neuroimaging to measure brain structure of males and females at age 16 and again at age 19 to view the changes occurring during late adolescence. They also measured mindfulness, emotional self-regulation, attention, inhibitory control, frustration, as well as behavioral aggression and depressive mood. High levels of mindfulness were found to be associated with higher levels of cognitive reappraisal, attention and inhibitory control, and lower levels of self-reported frustration, aggression and depressive mood. In other words, the adolescents who were very mindful were in better control of their emotions.

 

Friedel and colleagues then compared the brains at 16 years to those at 19 years and observed the expected thinning of cortical regions over this period. They found that mindfulness was associated with less thinning of an area called the Insula and that this was also associated with intelligence. They also found that the higher the level of mindfulness the less thinning of the Insula occurred and the higher the IQ test score.

 

These are intriguing findings. The Insula is an area of the cortex that has been found to be associated with interoceptive awareness, that is with the individual’s sensitivity to and awareness of their internal state. This is important for regulating emotions as the first step in regulating is actually becoming aware that they are occurring. Hence, the results suggest that the improved emotion regulation that is associated with mindfulness during late adolescence may be due to improved awareness of the emotional state and that this is due to less thinning of the Insula region of the cortex.

 

So, develop the brain mindfully and develop a more in-control teen.
