The exploration of meditation in the neuroscience of attention and consciousness.

Cogn Process. 2009 Dec 30;

Authors: Raffone A, Srinivasan N

Many recent behavioral and neuroscientific studies have revealed the importance of investigating meditation states and traits to achieve an increased understanding of cognitive and affective neuroplasticity, attention and self-awareness, as well as for their increasingly recognized clinical relevance. The investigation of states and traits related to meditation has especially pronounced implications for the neuroscience of attention, consciousness, self-awareness, empathy and theory of mind. In this article we present the main features of meditation-based mental training and characterize the current scientific approach to meditation states and traits with special reference to attention and consciousness, in light of the articles contributed to this issue.

Effects of mindful and non-mindful exercises on people with depression: a systematic review.

Br J Clin Psychol. 2008 Sep;47(Pt 3):303-22

Authors: Tsang HW, Chan EP, Cheung WM

PURPOSE: An emerging body of evidence has shown the therapeutic effect of both mindful and non-mindful physical exercises on the treatment of depression. The purpose of this study is to examine the effectiveness of mindful and non-mindful physical exercises as an intervention in managing depression or depressive symptoms based on a systematic literature review. METHODS: Our review was conducted among five electronic databases to identify randomized controlled trials (RCTs), which tested the effects of mindful or/and non-mindful physical exercises on depression. Studies were classified according to the baseline depression status of participants and its relation to allocation concealment, blinding at outcome assessment, follow-up, and whether intention to treat analysis was employed. RESULTS: The results based on 12 RCTs indicated that both the mindful and non-mindful physical exercises were effective in their short-term effect in reducing depression levels or depressive symptoms. However, most of studies had methodological problems that only small sample size was used, and the maintenance effects of physical exercise were not reported. Specific comparisons between RCTs on mindful and non-mindful exercises were not performed because of the limitations on the designs. CONCLUSIONS: We recommend that more well-controlled studies have to be conducted in the future to address the short- and long-term effects of physical exercise on alleviating depression. Efforts should be focused on unveiling the differential effects of mindful and non-mindful exercises on depression and the underlying mechanisms of their therapeutic action.

Usefulness of mindfulness-based cognitive therapy for treating insomnia in patients with anxiety disorders: a pilot study.

J Nerv Ment Dis. 2008 Jun;196(6):501-3

Authors: Yook K, Lee SH, Ryu M, Kim KH, Choi TK, Suh SY, Kim YW, Kim B, Kim MY, Kim MJ

The objective of this study was to examine the usefulness of a mindfulness-based cognitive therapy (MBCT) for treating insomnia symptoms in patients with anxiety disorder. Nineteen patients with anxiety disorder were assigned to an 8-week MBCT clinical trial. Participants showed significant improvement in Pittsburgh Sleep Quality Index (Z = -3.46, p = 0.00), Penn State Worry Questionnaire (Z = -3.83, p = 0.00), Ruminative Response Scale (Z = -3.83, p = 0.00), Hamilton Anxiety Rating Scale (Z = -3.73, p = 0.00), and Hamilton Depression Rating Scale scores (Z = -3.06, p = 0.00) at the end of the 8-week program as compared with baseline. Multiple regression analysis showed that baseline Penn State Worry Questionnaire scores were associated with baseline Pittsburgh Sleep Quality Index scores. These findings suggest that MBCT can be effective at relieving insomnia symptoms by reducing worry associated sleep disturbances in patients with anxiety disorder. However, well-designed, randomized, controlled trials are needed to confirm our findings.

Tactile acuity in experienced Tai Chi practitioners: evidence for use dependent plasticity as an effect of sensory-attentional training.

Exp Brain Res. 2008 May 30;

Authors: Kerr CE, Shaw JR, Wasserman RH, Chen VW, Kanojia A, Bayer T, Kelley JM

The PERCRO – Perceptual Robotics Laboratory, from Scuola Superiore Sant’Anna, Pisa, is presenting a series of lectures by Alan Wallace on June 17th, 18th and 19th, 2008.

Dr. Wallace, a scholar and practitioner of Buddhism since 1970, has taught Buddhist theory and meditation worldwide since 1976. Having devoted fourteen years to training as a Tibetan Buddhist monk, ordained by H. H. the Dalai Lama, he went on to earn an undergraduate degree in physics and the philosophy of science at Amherst College and a doctorate in religious studies at Stanford. With his unique background, Alan Wallace brings deep experience and applied skills to the challenge of integrating traditional Indo-Tibetan Buddhism with the modern world, continually seeking innovative ways to integrate Buddhist contemplative practices with Western science to advance the study of the mind.

The three lectures will deal with the results of the collaboration between psychologists and neuroscientists that took physiological and psychological measurements of people involved in an intensive mediation retreat; the convergences between Buddhism and Physics and the Question of Free Will.

Meditation with yoga, group therapy with hypnosis, and psychoeducation for long-term depressed mood: a randomized pilot trial.

J Clin Psychol. 2008 May 5;

Authors: Butler LD, Waelde LC, Hastings TA, Chen XH, Symons B, Marshall J, Kaufman A, Nagy TF, Blasey CM, Seibert EO, Spiegel D

This randomized pilot study investigated the effects of meditation with yoga (and psychoeducation) versus group therapy with hypnosis (and psychoeducation) versus psychoeducation alone on diagnostic status and symptom levels among 46 individuals with long-term depressive disorders. Results indicate that significantly more meditation group participants experienced a remission than did controls at 9-month follow-up. Eight hypnosis group participants also experienced a remission, but the difference from controls was not statistically significant. Three control participants, but no meditation or hypnosis participants, developed a new depressive episode during the study, though this difference did not reach statistical significance in any case. Although all groups reported some reduction in symptom levels, they did not differ significantly in that outcome. Overall, these results suggest that these two interventions show promise for treating low- to moderate-level depression. (c) 2008 Wiley Periodicals, Inc. J Clin Psychol 64(7): 1-15, 2008.

Attention regulation and monitoring in meditation.

Trends Cogn Sci. 2008 Mar 6;

Authors: Lutz A, Slagter HA, Dunne JD, Davidson RJ

Meditation can be conceptualized as a family of complex emotional and attentional regulatory training regimes developed for various ends, including the cultivation of well-being and emotional balance. Among these various practices, there are two styles that are commonly studied. One style, focused attention meditation, entails the voluntary focusing of attention on a chosen object. The other style, open monitoring meditation, involves nonreactive monitoring of the content of experience from moment to moment. The potential regulatory functions of these practices on attention and emotion processes could have a long-term impact on the brain and behavior.

Improving quality of life using compound mind-body therapies: evaluation of a course intervention with body movement and breath therapy, guided imagery, chakra experiencing and mindfulness meditation.

Qual Life Res. 2008 Mar 7;

Authors: Fernros L, Furhoff AK, Wändell PE

Objective Assess changes in quality of life and in sense of coherence (SOC), after an intervention involving a self-development course using mind-body medicine (MBM) activities. Design A questionnaire study using a health-related quality of life (HRQOL) instrument, the SWEDQUAL, with 13 subscales and scores ranging from 0 to 100, combined with the SOC-13 scale, healthcare utilisation, medication and sick listing data. Setting A training centre for MBM. Eligible course attendants (study group, SG, n = 83) assessed their HRQOL before and 6 months after a 1-week course. A control group (CG) of individuals who had previously attended the course (n = 69), matched for age, sex and length of course time to the SG, also made assessments. Main outcome Changes in HRQOL and SOC in SG and CG. Results Of the 13 HRQOL subscales, eight showed clinically significant improvement in the SG (>9%, p < 0.01), namely, General health perceptions (9%), Emotional well-being [negative (45%) and positive (26%)], Cognitive functioning (24%), Sleep (15%), Pain (10%), Role limitation due to emotional health (22%) and Family functioning (16%). Sexual, marital and physical function and role in the SG as well as all CG scores were similar to average population values. The assessed SOC also improved in the SG after intervention (p < 0.01), challenging previous statements of 'the stableness of SOC'. Use of psychotropic medication was slightly reduced in the younger aged SG participants after intervention. Conclusions This group of men and women (SG), starting from a clinically significant low health assessment, had improved their HRQOL and SOC after the course intervention.

Blood Pressure Response to Transcendental Meditation: A Meta-analysis.

Am J Hypertens. 2008 Mar;21(3):310-6

Authors: Anderson JW, Liu C, Kryscio RJ

BackgroundPrior clinical trials suggest that the Transcendental Meditation technique may decrease blood pressure of normotensive and hypertensive individuals but study-quality issues have been raised. This study was designed to assess effects of Transcendental Meditation on blood pressure using objective quality assessments and meta-analyses.MethodsPubMed and Cochrane databases through December 2006 and collected publications on Transcendental Meditation were searched. Randomized, controlled trials comparing blood pressure responses to the Transcendental Meditation technique with a control group were evaluated. Primary outcome measures were changes in systolic and diastolic blood pressure after practicing Transcendental Meditation or following control procedures. A specific rating system (0-20 points) was used to evaluate studies and random-effects models were used for meta-analyses.ResultsNine randomized, controlled trials met eligibility criteria. Study-quality scores ranged from low (score, 7) to high (16) with three studies of high quality (15 or 16) and three of acceptable quality (11 or 12). The random-effects meta-analysis model for systolic and diastolic blood pressure, respectively, indicated that Transcendental Meditation, compared to control, was associated with the following changes: -4.7 mm Hg (95% confidence interval (CI), -7.4 to -1.9 mm Hg) and -3.2 mm Hg (95% CI, -5.4 to -1.3 mm Hg). Subgroup analyses of hypertensive groups and high-quality studies showed similar reductions.ConclusionsThe regular practice of Transcendental Meditation may have the potential to reduce systolic and diastolic blood pressure by approximately 4.7 and 3.2 mm Hg, respectively. These are clinically meaningful changes.American Journal of Hypertension (2008) doi:10.1038/ajh.2007.65American Journal of Hypertension (2008) doi:10.1038/ajh.2007.65.

Mindfulness: an intervention for anxiety in schizophrenia.

J Psychosoc Nurs Ment Health Serv. 2007 Nov;45(11):23-9

Authors: Davis LW, Strasburger AM, Brown LF

Despite evidence that individuals with schizophrenia spectrum disorders experience significant and persistent symptoms of anxiety, there are few reports of the use of empirically supported treatments for anxiety in this population. This article describes how we have tried to adapt mindfulness interventions to help individuals with schizophrenia who experience significant anxiety symptoms. Although mindfulness has been widely used to help individuals without psychosis, to our knowledge, this is the first study adapting it to help those with schizophrenia manage worry and stress. We provide an overview of the intervention and use an individual example to describe how our treatment development group responded. We also explore directions for future research of mindfulness interventions for schizophrenia.

Immediate effect of two yoga-based relaxation techniques on performance in a letter-cancellation task.

Percept Mot Skills. 2007 Oct;105(2):379-85

Authors: Sarang SP, Telles S

The performance in a six-letter cancellation task was assessed with 69 male volunteers, ages 18 to 48 years, immediately before and after two yoga-based relaxation techniques and a control session of equal duration. The techniques were Cyclic Meditation and Supine Rest. Cyclic Meditation consists of alternating cycles of yoga postures and supine rest. After both practices, the net scores were significantly higher, although the magnitude of change was more after Cyclic Meditation than after Supine Rest (24.9% versus 13.6%). There was reduction in scores for wrong cancellations after Cyclic Meditation and not after Supine Rest. The control group showed no change. The results suggest that Cyclic Meditation brings about a greater improvement in performance in this task, which requires selective attention, concentration, visual scanning abilities, and a repetitive motor response.

Effects of natural stress relief meditation on trait anxiety: a pilot study.

Psychol Rep. 2007 Aug;101(1):130-4

Authors: Coppola F

Natural Stress Relief meditation, a mental technique which is practiced for 15 minutes twice a day, aims to reduce stress and anxiety by eliciting a specific state of physiological rest along with mental alertness. The meditation is taught in a self-administered program, requiring one hour of training during the first three days, followed by the regular twice daily practice. Each 15-min. session consists in sitting quietly with closed eyes while applying a specific mental procedure. To test the effectiveness of meditation in reducing trait anxiety, Spielberger's State-Trait Anxiety Inventory was administered to 25 participants four times over a 3-wk. period: one week before starting to practice the meditation, a few hours before starting, 1 wk. after, and 2 wk. after. The difference in Trait Anxiety score between pretreatment and before starting the practice was not significant, while it was significant both after the first week of practice (Cohen d=.46) and after the first 2 wk. of practice (d=.67).

Short-term meditation training improves attention and self-regulation.

Recent studies suggest that months to years of intensive and systematic meditation training can improve attention. However, the lengthy training required has made it difficult to use random assignment of participants to conditions to confirm these findings. This article shows that a group randomly assigned to 5 days of meditation practice with the integrative body-mind training method shows significantly better attention and control of stress than a similarly chosen control group given relaxation training. The training method comes from traditional Chinese medicine and incorporates aspects of other meditation and mindfulness training. Compared with the control group, the experimental group of 40 undergraduate Chinese students given 5 days of 20-min integrative training showed greater improvement in conflict scores on the Attention Network Test, lower anxiety, depression, anger, and fatigue, and higher vigor on the Profile of Mood States scale, a significant decrease in stress-related cortisol, and an increase in immunoreactivity. These results provide a convenient method for studying the influence of meditation training by using experimental and control methods similar to those used to test drugs or other interventions.

Mastery of the Mind East and West: Excellence in Being and Doing and Everyday Happiness.

Ann N Y Acad Sci. 2007 Sep 28;

Authors: Brown DP

Western psychological research on positive psychology and Buddhism have recently converged in their emphasis on the development of positive states, like states of excellence and veryday happiness. Yet, these traditions differ in their approaches to positive states, with respect to a state-trait and doing-being distinction. Western scientific research on peak performance emphasizes discontinuous, time-limited peak performance states wherein individuals do things extraordinarily well in sports and in the arts. The Eastern spiritual traditions emphasize continuous excellence of being, in the form of traits or character strengths. In both traditions mental imagery is a key ingredient to excellence training. With respect to everyday happiness, Western psychological research has focused on the role of meaning systems in the transformation of flow states into vital engagement in everyday life, while Buddhism stresses the role of meditation training to gain mastery over all levels of mind that leads to everyday happiness. Rorschach and tachistoscopic research on advanced meditators suggests that advance meditators have gained unusual mastery over states of mind not yet documented in the Western psychological research on positive psychology.

Survival in HIV-1-positve adults practicing psychological or spiritual activities for one year.

Altern Ther Health Med. 2007 Sep-Oct;13(5):18-20, 22-4

Authors: Fitzpatrick AL, Standish LJ, Berger J, Kim JG, Calabrese C, Polissar N

OBJECTIVE: To investigate associations between survival and use of psychological and spiritual activities practiced over 1 year in HIV-positive (HIV+) patients. METHOD: Nine hundred one HIV+ adults living in the United States using at least 1 form of complementary and alternative medicine (CAM) completed a questionnaire 3 times between 1995 and 1998. Information on specific mind-body therapies included psychotherapy (group therapy, support groups, individual therapy) and spiritual therapies (self-defined "spiritual" activities, prayer, meditation, affirmations, psychic healing, visualizations). Subsequent death was ascertained from the National Death Index (NDI). Cox proportional-hazards regression assessed risk of death through 1999. RESULTS: Use of any psychological therapy reported in both the 6-month and 12-month follow-up questionnaires (1 year continuous use) was associated with a reduced risk of death (hazard ratio [HR]: 0.5, 95% CI: 0.3-0.9) adjusted for income, clinical acquired immune deficiency syndrome, CD4 count, smoking, alcohol use, and use of antiretroviral therapy or highly active antiretroviral therapy (HAART). The relationship between spiritual activities and survival was modified by use of HAART, which may reflect severity of illness. Individuals not currently using HAART and who participated in spiritual activities over the previous year were found to be at a reduced risk of death (HR: 0.4, 95% CI: 0.2-0.9) compared to those not practicing spirituality. CONCLUSIONS: Participation in spiritual and psychological therapies may be related to beneficial clinical outcomes in HIV+ individuals, including improved survival. Due to the self-selection of therapies in this observational cohort, it is not possible to distinguish use of the therapies from other characteristics or activities of the people participating in them.

Relationships between mindfulness practice and levels of mindfulness, medical and psychological symptoms and well-being in a mindfulness-based stress reduction program.

J Behav Med. 2007 Sep 25;

Authors: Carmody J, Baer RA

Relationships were investigated between home practice of mindfulness meditation exercises and levels of mindfulness, medical and psychological symptoms, perceived stress, and psychological well-being in a sample of 174 adults in a clinical Mindfulness-Based Stress Reduction (MBSR) program. This is an 8- session group program for individuals dealing with stress-related problems, illness, anxiety, and chronic pain. Participants completed measures of mindfulness, perceived stress, symptoms, and well-being at pre- and post-MBSR, and monitored their home practice time throughout the intervention. Results showed increases in mindfulness and well-being, and decreases in stress and symptoms, from pre- to post-MBSR. Time spent engaging in home practice of formal meditation exercises (body scan, yoga, sitting meditation) was significantly related to extent of improvement in most facets of mindfulness and several measures of symptoms and well-being. Increases in mindfulness were found to mediate the relationships between formal mindfulness practice and improvements in psychological functioning, suggesting that the practice of mindfulness meditation leads to increases in mindfulness, which in turn leads to symptom reduction and improved well-being.
