Change Major Depression Brain Chemistry with Mindfulness

MBCT Major Depression2 Li

“Mindfulness-based cognitive therapy helps participants in the classes to see more clearly the patterns of the mind; and to learn how to recognize when their mood is beginning to go down. It helps break the link between negative mood and the negative thinking that it would normally have triggered. Participants develop the capacity to allow distressing mood, thoughts and sensations to come and go, without having to battle with them. They find that they can stay in touch with the present moment, without having to ruminate about the past, or worry about the future.” – Center for Suicide Research

 

Major Depressive Disorder (MDD) is a severe mood disorder that includes mood dysregulation and cognitive impairment. It is estimated that 16 million adults in the U.S. (6.9% of the population suffered from major depression in the past year and affects females (8.4%) to a great extent than males (5.2%). It’s the second-leading cause of disability in the world following heart disease. It has also been shown that depression is, to a large extent, inherited, but can also be affected by the environment. Since the genes basically encode when, where, and how chemicals are produced, it is likely that there are changes in brain chemistry produced by the genes responsible for Major Depressive Disorder.

 

The usual treatment of choice for MDD is drug treatment. This supports the altered brain chemistry notion for MDD since the most effective treatment for MDD, drug treatment, changes brain chemistry. In fact, it is estimated that 10% of the U.S. population is taking some form of antidepressant medication. But a substantial proportion of patients (~40%) do not respond to drug treatment. In addition, the drugs can have nasty side effects. So, there is need to explore other treatment options.

 

Mindfulness meditation is a safe alternative that has been shown to be effective for major depressive disorder even in individuals who do not respond to drug treatment. Mindfulness Based Cognitive Therapy (MBCT) was developed specifically to treat depression and has been shown to be very effective in treating existing depression and preventing relapse when depression is in remission. It makes sense that if altered brain chemistry underlies MDD and that MBCT is an effective treatment for MDD, then MBCT must in some way change brain chemistry. In today’s Research News article “Evaluating metabolites in patients with major depressive disorder who received mindfulness-based cognitive therapy and healthy controls using short echo MRSI at 7 Tesla”

Li and colleagues explore brain chemistry changes in Major Depressive Disorder (MDD) and the effects of Mindfulness Based Cognitive Therapy (MBCT) on those brain chemistry changes.

 

They recruited patients who were diagnosed with MDD but who were not currently taking antidepressant drugs and who were not practicing meditation or yoga. The brains of these patients and healthy controls were scanned with a powerful imaging technique called Magnetic Resonance Spectroscopic Imaging (MRSI). It is capable of non-invasively detecting levels of particular chemicals in the brain. The patients then received an 8-week MBCT group therapy followed by rescanning of the brains for the same chemicals.

 

They found that the MDD patients compared to healthy controls had elevated levels of choline-containing compounds and decreased levels of N-acetyl aspartate, myo-inositol, and glutathione.

These chemicals are breakdown products of active brain chemicals (metabolites). These are all markers of brain function. The heightened levels of choline-containing compounds suggests that there is with increased cell density and/or membrane turnover in MDD. The decreased levels of N-acetyl aspartate suggest that there is a loss of neurons or neuronal function in MDD. The decreased levels of myo-inositol suggest that there is a loss of or dysfunction of glial cells in MDD. Finally, the decreased levels of glutathione suggest that there is a lower level of neuron excitation in the brain in MDD.

 

Importantly, Li and colleagues found that MBCT significantly reduced depression levels and at the same time normalized the levels of all of the metabolites that had abnormal levels in the patients. These are potentially important results. They demonstrate altered brain chemistry in MDD suggestive of dysfunction in the normal activities of the nervous system and point to potential causal factors in MDD. They also provide suggestions as to how MBCT changes the brain to effectively treat MDD.

 

It should be noted that the changes in metabolites in Major Depressive Disorder may be the result of the depression rather than its cause. The fact that the changes vanished after treatment reduced depression tends to support this contention. It is a complex disease effecting the most complex entity in the universe, the human brain. Hence, there is still a lot of work to do to determine the causal factors in MDD.

 

Regardless, change major depression brain chemistry with mindfulness.

Change Brain Activity in Depression with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Skeptics, of course, may ask what good are a few brain changes if the psychological effects aren’t simultaneously being illustrated? Luckily, there’s good evidence for those as well, with studies reporting that meditation helps relieve our subjective levels of anxiety and depression, and improve attention, concentration, and overall psychological well-being.”Alice Walton

 

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. The nervous system is constantly changing and adapting to the environment. For example, the brain area that controls the right index finger has been found to be larger in blind subjects who use braille than in sighted individuals.  Similarly, cab drivers in London who navigate the twisting streets of the city, have a larger hippocampus, which is involved in spatial navigation, than predefined route bus drivers. Hence experience changes size, activity, and connectivity of the brain. These changes in the brain are called neuroplasticity.

 

Over the last decade neuroscience has studied the effects of contemplative practices on the brain and has demonstrated that these practices produce neuroplastic changes in widespread areas. Indeed, mindfulness practices have been shown to not only alter how we think and feel but also to alter the nervous system, producing changes in the size, activity, and connectivity of specific structures and systems in the nervous system. Depression has been shown to also involve changes to the nervous system and is significantly improved by mindfulness practices. As a result of mindfulness practices’ ability to alter the brain and relieve depression, these practices have been incorporated into various psychotherapies for depression.

 

Mindfulness Based Cognitive Therapy (MBCT) was specifically developed to treat depression. It has been shown to be remarkably effective. Putting all these pieces together, it would seem likely that MBCT relieves depression by altering neural systems. In today’s Research News article “Multi-dimensional modulations of α and γ cortical dynamics following mindfulness-based cognitive therapy in Major Depressive Disorder”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1184978338192757/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4454126/

Schoenberg and Speckens investigated changes in brain activity produced by MBCT using sophisticated techniques to explore the electrical activity that can be recorded from various regions of the scalp (Electroencephalogram, EEG). They compared patients with major depressive disorder who were randomly assigned to receive 8-weeks of group Mindfulness Based Cognitive Therapy (MBCT) or treatment as usual, waitlist control. They found that MBCT treatment produced clinically significant improvements in depressive symptoms, self-compassion, over identification with painful thoughts and feelings, and mindfulness. This is not surprising, and replicates the well-established finding that MBCT is highly effective in treating depression.

 

They recorded the EEG of both groups while they performed a Go/NoGo task. Performance on this task has been shown to be deficient in depressed patients and indicates deficient executive function. They found that MBCT significantly downregulated α and γ power in the electrical activity of the brain. This indicates that there was and increase the excitability of the cerebral cortex. This is generally associated with greater positive mood and decreased negative emotions. This suggests that MBCT may relive depression by its effects on the neural systems underlying the depressed mood.

 

They also found an enhancement of the α-desynchronisation occurring in response to the Go/NoGo task when negative material was presented, but decreased α-desynchronisation when positive material was presented. This suggests that MBCT activates the neural networks underlying positive emotion. These are the systems that are usually relatively inactive in depression. This again suggests that MBCT may relieve depression by enhancing the activity of neural systems responsible for positive mood, thus working in opposition to the negative mood so characteristic of depression.

 

Finally, they found that MBCT increased intra-hemispheric α-coherence of the fronto-parietal circuit. This coherence has been shown to be related to improved attention and reduced mind wandering. In depression, mind wandering is highly related to rumination which tends to reinforce and support the depressed state. This suggests that MBCT may relive depression by enhancing the coherence of neural systems responsible for attention, thus inhibiting the mind wandering and rumination so characteristic of depression.

 

Hence the present study found evidence for changed electrical dynamics in the cortex of depressed patients following Mindfulness Based Cognitive Therapy (MBCT). The changes that were observed reflect changed processing of emotional information and attention, such that positive mood was enhanced, negative mood was reduced, and mind wandering and rumination decreased. All of these processes tend to counteract depression and may at least in part be responsible for the effectiveness of MBCT in treating depression.

 

So, change brain activity in depression with mindfulness.

Disrupt Suicidal Thoughts with Mindfulness  

“Did you really want to die?”
“No one commits suicide because they want to die.”
“Then why do they do it?”
“Because they want to stop the pain.”
  ― Tiffanie DeBartolo

 

After cancer and heart disease, suicide accounts for more years of life lost than any other cause. Around 43,000 people take their own lives each year in the US. Someone dies from suicide every 12.3 minutes. Worldwide over 800,000 people die by suicide every year. (Suicide Awareness Voices of Education). It is much more prevalent with males who account for 79% of suicides. The problem is far worse than these statistics suggest as it has been estimated that for every completed suicide there were 12 unsuccessful attempts. In other words, about a half a million people in the U.S. attempt suicide each year. Yet compared with other life threatening conditions there has been scant research on how to identify potential suicide attempters, intervene, and reduce suicidality.

 

Depression and other mood disorders are the number-one risk factor for suicide. More than 90% of people who kill themselves have a mental disorder, whether depression, bipolar disorder or some other diagnosis, according to the National Alliance on Mental Illness (NAMI). So, the best way to prevent suicide may be to treat the underlying cause. For many this means treating depression. Mindfulness training has been shown to reduce suicidality in substance abusers (see http://contemplative-studies.org/wp/index.php/2015/11/30/decrease-suicidality-with-mindfulness/). Mindfulness training has also been shown to be effective for treating depression (see http://contemplative-studies.org/wp/index.php/category/research-news/depression/). Mindfulness-Based Cognitive Therapy (MBCT) was developed specifically to treat depression and prevent relapse. So, it would seem reasonable to expect that MBCT would be effective in suicide prevention.

 

In today’s Research News article “Mindfulness-Based Cognitive Therapy (MBCT) Reduces the Association Between Depressive Symptoms and Suicidal Cognitions in Patients with a History of Suicidal Depression”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1158656587491599/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4655869/

Barnhofer and colleagues treated patients with a history of suicidal depression with eight weeks of either MBCT, Cognitive Psychoeducation (CE), or Treatment as Usual (TAU). They found that at the end of treatment the participants treated with MBCT had a significant reduction in suicidal thoughts while the other groups did not. For the CE and TAU groups there were strong and significant correlations between depression and suicidal thoughts. That is, for these groups, the higher the level of depression the higher the levels of suicidal thought. In contrast for the MBCT group the correlations were significantly weaker That is, there was a much weaker relationship between depression and suicidal thoughts after Mindfulness-Based Cognitive Therapy (MBCT) than Cognitive Psychoeducation (CE), or Treatment as Usual (TAU).

 

These are interesting and potentially important findings that MBCT can reduce suicidal thoughts and that it weakens the link between depression and suicidal thoughts. This makes sense as MBCT is designed to reprogram depressive thought processes, helping the patient to see that their typical ways of thinking about and assessing their experiences are faulty and tend to heighten depression and that looking at and interpreting their experiences in a more rational way can reduce depression. This, in turn, appears to reduce suicidal thinking.

 

These results clearly suggest that Mindfulness-Based Cognitive Therapy (MBCT) may be an effective program to prevent suicide in people with high levels of suicidal thinking. Since mindfulness training has been shown to reduce suicidality in drug abusers, the second most likely group to commit suicide, it would appear that mindfulness training is potentially an important method to prevent suicide.

 

So, disrupt suicidal thoughts with mindfulness.

Improve Inflammatory Bowel Disease with Mindfulness

 

MBCT inflammatory bowel disease - Schoultz2

“I don’t think anybody would argue that fact that we know inflammation in the body, which comes from a lot of different sources, is the basis for a lot of chronic health problems, so by controlling that, we would expect to see increased life expectancy … but if we’re not changing those things and just taking ibuprofen, I don’t know if we’re really going to make any headway in that, I feel like there are probably a lot of factors that we could change without medicating with risk.” –  Josie Znidarsic

“Inflammatory Bowel Disease (IBD) is a broad term that describes conditions with chronic or recurring immune response and inflammation of the gastrointestinal tract. The two most common inflammatory bowel diseases are ulcerative colitis and Crohn’s disease. Inflammation affects the entire digestive tract in Crohn’s disease and only the large intestine in ulcerative colitis. Both illnesses are characterized by an abnormal response to the body’s immune system.” (Centers for Disease Control and Prevention).

 

Inflammatory Bowel Disease affects about 1 –1.3 million in the United States and its incidence appears to be increasing worldwide. IBD is a relapsing disorder with symptoms appearing, disappearing, and reoccurring repeatedly. It is characterized by diarrhea, fever and fatigue, abdominal pain and cramping, blood in the stool, reduced appetite, and unintended weight loss. IBD sufferers may lose weight and even become malnourished because they cannot properly digest and absorb food. The cause of IBD is unknown, and until we understand more, prevention or a cure will not be possible. It is most frequently treated with drugs, particularly anti-inflammatory drugs and immune system suppressors. These treatments, however, have considerable troubling side effects and patients frequently do not comply with the regimen.

 

There is a need for effective treatments for IBD that are safe and have few if any side effects. Since contemplative practices have been shown to reduce inflammatory responses (see http://contemplative-studies.org/wp/index.php/category/research-news/inflammatory-response/), and irritable bowel syndrome (see http://contemplative-studies.org/wp/index.php/category/research-news/ibs/) and have very few if any adverse side effects, they would seem to be appropriate potential treatments for IBD.  In today’s Research News article “Mindfulness-based cognitive therapy for inflammatory bowel disease patients: findings from an exploratory pilot randomised controlled trial”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1138739702816621/?type=3&theaterhttp://www.ncbi.nlm.nih.gov/pmc/articles/PMC4549082/

Schoultz and colleagues perform a pilot test of the effectiveness of an 8-week Mindfulness Based Cognitive Therapy (MBCT) program for Inflammatory Bowel Disease compared to a standard care control group. They found that MBCT produced significant reductions in depression and

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1138739702816621/?type=3&theatersizes studied there were trends toward improvements in Chron’s disease and ulcerative colitis activity. All of these effects were sustained at a 6-month follow-up.

 

This study was a pilot study that had only a small number of patients. This makes it difficult to detect statistically significant results. So, it is impressive that reductions in depression and anxiety were significant and attest to the robustness of these effects. This, however, should not be a surprise as MBCT was developed specifically with the treatment of depression and anxiety in mind and there is an impressive array of scientific studies verifying its effectiveness (see http://contemplative-studies.org/wp/index.php/category/contemplative-practice/mbct/).

 

The study is potentially very important in that there were large non-significant trends toward effectiveness in reducing IBD activity in the patients. These possible effects of mindfulness may be due to its ability to reduce inflammation and also to its ability to reduce the physiological and psychological effects of stress (see http://contemplative-studies.org/wp/index.php/category/research-news/stress/) since stress has been shown to be a trigger for flares in IBD symptoms. These results strongly suggest that a much larger controlled study is called for investigating this potentially useful treatment for IBD.

 

So, improve inflammatory bowel disease with mindfulness.

Reduce Depression with Cyber-Mindfulness  

MBCT Depression Internet Beck2

 

“Our emotional reactions depend on the story we tell ourselves, the running commentary in the mind that interprets the data we receive through our senses.” ― Mark Williams,

 

Depression is widespread and debilitating. It is the most common mental illness affecting about 4% of the population worldwide. There are a number of treatments for depression the most common of which is antidepressant medication. But the drugs do not always work and can become ineffective over time. They can also have troublesome side effects. So, there is a need to discover safe and effective alternative treatments.

 

Mindfulness training has been shown to be an effective treatment for depression (see http://contemplative-studies.org/wp/index.php/category/research-news/depression/). Cognitive Behavioral Therapy (CBT) has been shown to be effective for depression by altering the ways people think about and process events that occur in their lives. Mindfulness Based Cognitive Behavioral Therapy (MBCT) adds mindfulness training to CBT. It was designed specifically to treat depression and has been shown to be effective even with people who do not respond to antidepressant medications (see http://contemplative-studies.org/wp/index.php/2015/07/17/dealing-with-major-depression-when-drugs-fail/). MBCT has been so effective that the British Medical Service considers it a treatment of choice for depression.

 

MBCT can be delivered either individually or in groups. But, it requires that a highly trained therapist lead the process and it can be delivered to only a limited number of people at a time. Hence, it is relatively expensive to deliver. Also, it requires the patients to come to a practitioner’s facility on a regular basis over 8 to 12 weeks. This can be inconvenient for many and impossible for others. In addition, depressed individuals lack energy and motivation and many simply can’t find the strength to attend regular sessions. So, there is a need to develop better ways to deliver therapy. The internet provides a mechanism that could potentially overcome many of these drawbacks to face-to-face delivery of MBCT. It’s low cost and widely available and can be accessed when the patient feels up to it.

 

In today’s Research News article “PS2-43: Internet Delivered Mindfulness-based Cognitive Therapy for Reducing Residual Depressive Symptoms: An Open Trial and Quasi-experimental Comparison to Propensity Matched Controls”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1134263793264212/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4453426/

Beck and colleagues developed and tested an 8-session MBCT program delivered over the internet to recurrently depressed patients. Compared to treatment as usual for depression internet based MBCT produced a clinically significant decrease in depression with large effect size.

 

These are very exciting results. The cyber MBCT program is highly scalable and can be delivered to large numbers of depression sufferers at low cost. Because it’s delivered over the internet, it is convenient and available to patients who live in areas without access to clinics. The program needs to be compared to face-to-face MBCT. But, these results suggest that its effectiveness is comparable. Further research is definitely called for.

 

So, reduce depression with cyber-mindfulness.

 

“Unhappiness itself is not the problem—it is an inherent and unavoidable part of being alive. Rather, it’s the harshly negative views of ourselves that can be switched on by unhappy moods that entangle us. It is these views that transform passing sadness into persistent unhappiness and depression. Once these harsh, negative views of ourselves are activated, not only do they affect our mind, they also have profound effects on our body—and then the body in turn has profound effects on the mind and emotions.”  ― Mark Williams

When Nothing Else Works for Depression Mindfulness Can!

 

“When I see new patients with treatment-resistant depression, I tell them that if they want to borrow some of my optimism, they’re welcome to it. . .Despite how it feels, lots of people have been through this and lots of people get better.” – Ian Cook

 

Major Depression is the most common mental illness affecting over 6% of the population. The first line treatment is antidepressant drugs. But, depression can be difficult to treat. 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. This leaves a third of all patients treated without success. These patients are deemed to have treatment-resistant depression.

 

Being depressed and not responding to treatment 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. In today’s Research News article “Transcranial Magnetic Stimulation, and Depression Specific Yoga and Mindfulness Based Cognitive Therapy in Management of Treatment Resistant Depression: Review and Some Data on Efficacy”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1130698403620751/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4609854/

Pradhan and colleagues review the research literature on alternative treatments for treatment-resistant depression; ketamine, transcranial magnetic stimulation, and yoga and mindfulness interventions.

 

They report that infusion of the drug Ketamine, a glutamate receptor (NMDA) antagonist, has been shown to be effective quickly for treatment-resistant depression. Unfortunately its effects last only about a week and it has some troubling side effects. Another treatment, repetitive transcranial magnetic stimulation (rTMS) stimulates the human cortex through external magnetic stimulation and can be applied non-invasively. It appears to be effective for the relief of treatment-resistant depression in about half of the patients and it has very few and mild side effects. But treatments must be provided on a daily basis in a doctor’s office. So, it is very inconvenient and thereby often impossible for the patients.

 

Contemplative practices such as meditation and yoga are low cost and generally safe with few if any side effects. They have been shown to be effective for depression and to prevent relapse (see http://contemplative-studies.org/wp/index.php/category/research-news/depression/). A combination of cognitive behavioral therapy with mindfulness and meditation techniques, Mindfulness Based Cognitive Therapy (MBCT) has been demonstrated to be effective for depression even after drugs have failed to relieve the depression (see http://contemplative-studies.org/wp/index.php/2015/07/17/dealing-with-major-depression-when-drugs-fail/).

Pradhan and colleagues perform a pilot study of a combination of MBCT and yoga they term Depression Specific Y-MBCT (DepS Y-MBCT) applied to treatment-resistant depression patients, one third of whom had suicidal tendencies. Of the 32 participants, 27 achieved remission from depression that was maintained for at least two months. These are exciting findings. A low cost and safe therapeutic technique combining mindfulness, yoga, and cognitive behavioral therapy produced and 85% remission rate for patients who did not respond to other treatments. Of course, these results need to be repeated in a randomized clinical trial. But, these results certainly justify the effort.

It is interesting that a disease like depression that is thought to be organically based in defective brain chemistry can be treated by a behavioral treatment. But, yoga and meditation have been found to alter the structure, connectivity, and chemistry of the brain. So, it may not be so mysterious how a behavioral treatment might be effective for a primarily physiological disorder. The mind and body are one. Treating the mind can also treat the body. This is one of the major messages of the alternative medical treatment movement.

 

So, apply mindfulness when nothing else works for depression.
