Mind-Body Practices and the Adolescent Brain: Clinical Neuroimaging Studies

Yoga perspective on personal excellence and well-being

The discussions on conceptualization, operationalization, measures, and means of well-being (WB) and personal excellence (PE) are dynamic and debatable. Therefore, this study aims to coin a perspective of PE based on the Patanjali Yoga Sūtra (PYS). For this, professional, psychological, philosophical, and yogic perspectives of WB and PE are analyzed to derive a viable yogic framework for PE. The WB and the consciousness-based constructs of PE are discussed in terms of psychic tensions (PTs) (nescience, egoism, attachment, aversion, and love for life), yogic hindrances (YHs) (illness, apathy, doubt, procrastination, laziness, over somatosensory indulgence, delusion, inability, and unstable progress), psychosomatic impairments (pain, despair, tremors, arrhythmic breath), and yogic aids (wellness, intrinsic motivation, faith, role punctuality, physical activity, sensory control, clarity, competence, and sustainable progress). The PYS operationalizes PE as the dynamic level of WB and self-awareness until one attains Dharmamegha Samādhi (super consciousness). Lastly, Ashtanga Yoga (AY) is discussed as a universal principle, process, and practice for thinning PTs, vanishing YHs, empowering holistic WB, awakening extrasensory potentials, advancing self-awareness, and PE. This study will be a pioneering base for further observational and interventional studies to develop measures and personalized protocols for PE.

Gender and Ethnicity: Are they Associated with Differential Outcomes of a Biopsychosocial Social-Emotional Learning Program?

Context:

Social-emotional learning (SEL) program outcomes may be enhanced when programs take into account gender and ethnicity differences, yet few studies directly examine these variables. The limited literature further suggests improved outcomes accrue by integrating physiological techniques, such as yoga and meditation, directly into SEL curricula to reduce stress.

Aims:

This study investigated the association between outcomes of a yogic breath-based biopsychosocial SEL intervention across gender and ethnicity.

Methods:

Fifty-nine high school students were evaluated on 4 positive (self-esteem, identity formation, anger coping ability, planning, and concentration) and 3 negative SEL outcomes (impulsivity, distractibility, and endorsement of aggression). Using a repeated-measures design, group differences between gender and ethnicity were assessed.

Results and Conclusions:

Significant improvements on all 7 outcomes were found for the sample, suggesting that participants performed better after the intervention. There were neither significant differences between males and females on outcomes nor between different ethnic groups with the exception of African-Americans scoring lower on one of three emotion regulation outcomes. This study, one of the first to directly analyze SEL outcomes by sociodemographic variables, demonstrated the program's biopsychosocial approach was associated with beneficial SEL outcomes across genders and ethnicities. Future studies of biopsychosocial programs taking into account sociodemographics will allow SEL programs to be more effective across diverse populations.

Vagal Mediation of Low-Frequency Heart Rate Variability During Slow Yogic Breathing

OBJECTIVE

Changes in heart rate variability (HRV) associated with breathing (respiratory sinus arrhythmia) are known to be parasympathetically (vagally) mediated when the breathing rate is within the typical frequency range (9-24 breaths per minute [bpm]; high-frequency HRV). Slow yogic breathing occurs at rates below this range and increases low-frequency HRV power, which may additionally reflect a significant sympathetic component. Yogic breathing techniques are hypothesized to confer health benefits by increasing cardiac vagal control, but increases in low-frequency HRV power cannot unambiguously distinguish sympathetic from parasympathetic contributions. The aim of this study was to investigate the autonomic origins of changes in low-frequency HRV power due to slow-paced breathing.

METHODS

Six healthy young adults completed slow-paced breathing with a cadence derived from yogic breathing patterns. The paced breathing took place under conditions of sympathetic blockade, parasympathetic (vagal) blockade, and placebo. HRV spectral power was compared under 11 breathing rates during each session, in counterbalanced order with frequencies spanning the low-frequency range (4-9 bpm).

RESULTS

HRV power across the low-frequency range (4-9 bpm) was nearly eliminated (p = .016) by parasympathetic blockade (mean (SD) spectral power at breathing frequency = 4.1 (2.1)) compared with placebo (69.5 (8.1)). In contrast, spectral power during sympathetic blockade 70.2 (9.1) and placebo (69.5 (8.1)) was statistically indistinguishable (p = .671).

CONCLUSIONS

These findings clarify the interpretation of changes in HRV that occur during slow-paced breathing by showing that changes in low-frequency power under these conditions are almost entirely vagally mediated. Slow-paced breathing is an effective tool for cardiac vagal activation.

Mindfulness and meditation as an adjunctive treatment for adolescents involved in the juvenile justice system: Is repairing the brain and nervous system possible?

Adolescents involved in the juvenile justice system are prone to more traumatic events than other adolescents, leaving them in danger of developmental difficulties. Trauma exposure is predictive of poor outcomes including mental and physical health issues as well as criminal activity. Current treatment approaches either have a nominal effect on recidivism rates or increase the likelihood of future criminal offenses. This article explores adolescent brain development, the unique difficulties that juvenile justice youth face, and mindfulness meditation as an adjunctive treatment to system-based treatment. Mindfulness meditation may be a way to redress damage to the brain and facilitate healthy brain development, thus impacting prosocial behavior. Practice implications include integrating mindfulness meditation as an important part of rehabilitative efforts with juvenile justice youth.

A Breathing-Based Meditation Intervention for Patients With Major Depressive Disorder Following Inadequate Response to Antidepressants: A Randomized Pilot Study

OBJECTIVE

To evaluate feasibility, efficacy, and tolerability of Sudarshan Kriya yoga (SKY) as an adjunctive intervention in patients with major depressive disorder (MDD) with inadequate response to antidepressant treatment.

METHODS

Patients with MDD (defined by DSM-IV-TR) who were depressed despite ≥ 8 weeks of antidepressant treatment were randomized to SKY or a waitlist control (delayed yoga) arm for 8 weeks. The primary efficacy end point was change in 17-item Hamilton Depression Rating Scale (HDRS-17) total score from baseline to 2 months. The key secondary efficacy end points were change in Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) total scores. Analyses of the intent-to-treat (ITT) and completer sample were performed. The study was conducted at the University of Pennsylvania between October 2014 and December 2015.

RESULTS

In the ITT sample (n = 25), the SKY arm (n = 13) showed a greater improvement in HDRS-17 total score compared to waitlist control (n = 12) (-9.77 vs 0.50, P = .0032). SKY also showed greater reduction in BDI total score versus waitlist control (-17.23 vs -1.75, P = .0101). Mean changes in BAI total score from baseline were significantly greater for SKY than waitlist (ITT mean difference: -5.19; 95% CI, -0.93 to -9.34; P = .0097; completer mean difference: -6.23; 95% CI, -1.39 to -11.07; P = .0005). No adverse events were reported.

CONCLUSIONS

Results of this randomized, waitlist-controlled pilot study suggest the feasibility and promise of an adjunctive SKY-based intervention for patients with MDD who have not responded to antidepressants.
