Clinical effects of a yoga-based intervention for patients with schizophrenia - A six-month randomized controlled trial.

BACKGROUND: Yoga has shown promise as an add-on therapy for patients with schizophrenia. However, most studies have been short-term, with methodological limitations. METHODS: We conducted a six-month parallel-group randomized-controlled trial (with rater blinding) to evaluate the effectiveness of a yoga-based intervention in improving symptoms and quality of life in patients with schizophrenia. We recruited 110 patients from an urban tertiary hospital and a semi-urban community centre who met DSM 5 criteria for schizophrenia and were on stable medication for at least six weeks. Participants were randomly assigned to either yoga add-on therapy (YT) or treatment-as-usual (TAU) groups. Clinical assessments were conducted at baseline and at one, three and six months. The primary outcome was changes in positive/negative symptom scores and secondary outcomes included changes in quality of life, perceived stress and socio-occupational functioning. RESULTS: Intention to treat analysis with a longitudinal mixed model approach revealed a significant group-by-time interaction with the YT group showing medium effect improvements in negative symptoms (η2p = 0.06) and small effect improvements in positive symptoms (η2p = 0.012), WHOQOL-BREF quality of life [psychological well-being (η2p = 0.015) and environmental health (η2p = 0.048)] when compared to TAU. The patients successfully learned and performed yoga practices without reporting any significant adverse effects. DISCUSSION: Our findings suggest that yoga-based intervention may be a valuable adjuvant therapy for medication-stabilized patients with schizophrenia, especially in ameliorating negative symptoms and enhancing quality of life. Future controlled trials, including active physical interventions, are crucial to validate yoga's efficacy, optimize clinical use, and elucidate underlying mechanisms.

Mental Health Programme in India: Has the tide really turned?

Mental disorders in India form a major public health concern and the efforts to tackle these dates back to four decades, by way of the National Mental Health Programme (NMHP) and its operational arm, the District Mental Health Programme (DMHP). Although the progress of NMHP (and DMHP) was relatively slower till recently, the last 4-5 years have seen rapid strides with several initiatives, including (i) expansion of DMHPs to 90 per cent of the total districts of the country, (ii) the National Mental Health Policy and (iii) strengthening the Mental Health Legislation by way of providing explicit provisions for rights of persons with mental illnesses. Among others, factors responsible for this accelerated growth include the easily accessible digital technology as well as judicial activism. Federal and State cooperation is another notable feature of this expansion. In this review, the authors summarize the available information on the evolution of implementation and research aspects related to India's NMHP over the years and provide a case for the positive turn of events witnessed in the recent years. However, the authors caution that these are still baby steps and much more remains to be done.

Evidence-based integration of yoga in psychiatric practice.

Yoga has been put to test in clinical medicine to build evidence. There has been a steep rise in yoga research through 2010, threefold in the next decade. Despite challenges, clinicians have explored yoga intervention in several disorders. The available data have been examined using meta-analysis when there are more studies. Psychiatric disorders treated with yoga have attracted more research. Some examples include depression, schizophrenia, anxiety, obsessive-compulsive disorder (OCD), somatoform pain, addiction, mild cognitive impairment, and elderly and childhood disorders. Current manuscript focuses on highlighting the major steps towards generating evidence that have led to integration of yoga into psychiatry practice. It also discusses various challenges and the way forward.

Composition of yoga-philosophy based mental traits (Gunas) in major psychiatric disorders: A trans-diagnostic approach.

Yoga philosophy includes the theory of Tri-guna (three mental traits): sattva (signifies a tendency to 'goodness'), rajas (tendency towards 'activity'), and tamas (tendency towards "inertia"). This cross-sectional study aimed to understand the differences in the expression of gunas in patients suffering from major psychiatric disorders (n = 113, 40 females) and age-gender-education-matched healthy controls (HCs; n = 113, 40 females). Patients were diagnosed by a psychiatrist using DSM 5 criteria and suffered from the following disorders: depression (n = 30), schizophrenia (SCZ; n = 28), obsessive-compulsive disorder (OCD; n = 23), anxiety (n = 16), and bipolar affective disorder (BPAD; n = 16). Tri-gunas were assessed using a validated tool (Vedic Personality Inventory) and symptoms were assessed using standard scales as per the diagnosis. Multi-variate analysis of variance (MANOVA) was used to assess the differences in guna scores between HCs and patients, and between patients with different diagnoses. A two-tailed Pearson correlation was performed between the gunas and psychometric scales. Results revealed that HCs had significantly higher sattva traits as compared to patients (except those with OCD). Each psychiatric diagnosis also showed a specific guna configuration: (1) Anxiety disorders and OCD: High sattva-rajas, low tamas; (2) Depression: High sattva-tamas, low rajas; (3) Psychotic disorders (SCZ/BPAD): High tamo-rajas, low sattva. Significant positive correlations were observed between rajas traits and anxiety/OC/positive psychotic symptoms, negative psychotic symptoms and tamas traits, and sattva traits and OC symptoms. This finding has clinical implications, both to develop ways of predicting outcomes of psychiatric disorders, as well as to develop psycho-therapeutic and lifestyle interventions targeting the gunas.

Yoga and Integrative Healthcare: Lessons from the National Institute of Mental Health and Neurosciences (NIMHANS) in India.

Background: There is growing evidence and increasing interest for systemic integration of medicine (synergistic and evidence-based combination of different systems along with conventional biomedicine). The National Institute of Mental Health and Neurosciences (NIMHANS), an Institute of National Importance and a tertiary mental and neurological healthcare hospital situated in Bengaluru, India, has established one such integrative model. The present manuscript traces the history and describes the important steps followed in this integrative approach. Methodology: The NIMHANS model followed a stage-wise two-step approach: (1) First stage - Starting with Integration of Yoga: The process began more than a decade ago, with integrating yoga into a clinical department (rather than an exclusive research-based approach) of the institute which had relatively high clinical service load (For example, Department of Psychiatry in NIMHANS). Yoga was gradually formalized into academic and clinical activities (outpatient and inpatient services) by appointing a Yoga faculty with a medical background with an MD/PhD in Yoga. The research was primarily directed by the clinical observations of patients receiving yoga therapy. (2) Second stage: Adding an appropriate and compatible discipline from Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homeopathy (AYUSH) system (Ayurveda in this case): The center for yoga gradually evolved into the Department of Integrative Medicine with the appointment of faculty from the Ayurveda stream. In this model, specialists from each discipline provide clinical inputs after simultaneous consultation with the patient through systemic integration in clinical, academic, and research domains rather than mere co-location of AYUSH services with mainstream medicine. Conclusion: The NIMHANS model of integration suggests the application of yoga into mainstream clinical service as the first step toward integration. Yoga should be added as a formalized clinical discipline with systemic integration. Gradually, other feasible systems of traditional medicine from AYUSH can be integrated at a later stage in a step-by-step manner based on clinical practice and evidence.

Generic Yoga Modules for Clinical and Research Settings-Need of the Hour.

Yoga-based interventions offer significant promise in healthcare. However, meta-analyses of various yoga trials suggest that comparisons of trials are either not possible or difficult due to heterogeneity in therapeutic yoga interventions. Also, in view of emerging evidence for the role of therapeutic yoga, it is important to identify the specificity and validity of various yoga components being used in different trials. Efforts in this direction will be fruitful only if a systematic approach is adopted to develop yoga programs for various ailments. In this article, we emphasize the need for a "generic yoga" concept for designing a therapeutic yoga program for particular health issues, with the objectives of promoting scientific growth of therapeutic applications of yoga and widespread application of standardized therapeutic yoga programs within a biomedical framework. This generic therapeutic yoga will essentially highlight the development-validation process of uncopyrighted yoga programs; their components, benefits, and possible side-effects; and requirement for need-based modifications.

Yoga therapy for social cognition in schizophrenia: An experimental medicine-based randomized controlled trial.

Negative symptoms and cognitive deficits are difficult-to-treat symptoms of schizophrenia. In this single blind randomized controlled study, we compared change in social cognitive performance in persons with Schizophrenia (PWS) (as per DSM-5), after 6 weeks of yoga intervention with a waitlist control group. We also examined changes in putative Mirror Neuron System (MNS) activity measured by Transcranial Magnetic Stimulation (TMS) in a subset of sample (n = 30). 51 PWS stabilized on antipsychotic medication for at least 6 weeks, were assigned to add-on yoga therapy (YT) (n = 26) or waitlist (WL) (n = 25). Subjects in the YT group received add-on yoga therapy (20 sessions in 6 weeks). Both the groups continued their standard treatment and were assessed at baseline and after 6 weeks for social cognition, clinical symptoms and social disability. RM-ANOVA showed significant interaction between time and group for social cognition composite score (SCCS) (F = 42.09 [1,44], P < 0.001); negative symptoms (SANS) (F = 74.91 [1,45], P < 0.001); positive symptoms (SAPS) (F = 16.05 [1,45], P < 0.001) and social disability (GSDS) (F = 29.91 [1,46], P < 0.001). MNS activity had increased after 6 weeks in both groups but not of statistical significance. This study demonstrates that 6 weeks of add-on yoga therapy could improve social cognition in PWS compared to waitlist control subjects. However, the change in social cognition was not associated with a change in the putative MNS-activity. It necessiatates further studies to investigate the mechanistic processes of yoga and replicate these observations in a larger sample.

Tele-Yoga Therapy for Common Mental Health Disorders: Need for Assessment Tool and Guidelines.

INTRODUCTION: Tele-yoga is a cost-effective method of teaching yoga using cloud technology to relay from one source (trainer's venue) to multi-point video conferencing centers (participants' homes). However, there is a need to assess the tele-yoga trainer and the training itself to ensure safety and effectiveness. MATERIALS AND METHODS: The Tele-Yoga Trainers Assessment (TYTA) tool was developed through (a) review of existing tools, (b) key informant interviews, and (c) validation by experts. It was tested for its feasibility in six persons with common mental disorders. A trained yoga therapist conducted tele-yoga therapy sessions which was webcast from NIMHANS Integrated Center for Yoga to NIMHANS Center for Well-Being for the first 15 days and to the respective homes of the participants using "Skype" in the remaining 15 days. Participants were assessed on (a) mental well-being, (b) satisfaction with overall health and were administered the (c) TYTA tool on the 1st, 15th, and 30th day. RESULTS: The TYTA was easy to administer for assessing the performance of the yoga trainer. The qualitative case reports of individual participants depicted that over 30 days, mental well-being and satisfaction with overall health improved trainer's performance. CONCLUSION: Tele-yoga therapy is feasible with minimum technology and availability of good internet access at the relay and reception site. The trainer must be assessed for his/her suitability and be provided guidelines for achieving desired outcomes.

Yoga Module for Somatoform Pain Disorders: Development, Content Validation, and Feasibility Testing.

BACKGROUND: Yoga practices have been found to be useful in chronic pain conditions but studies focussing specifically on somatoform pain disorders (SPDs) are limited. AIMS: Current study aims to develop and test the feasibility of a yoga program for patients with SPDs. MATERIALS AND METHODOLOGY: Athorough search of traditional and contemporary literature was performed with the objective of formulating a yoga program for reducing chronic non-specific pain and associated psychological distress. Content validity of the program was then determined by taking the opinion of 18 yoga experts (who had >5 years of experience in treating mental health disorders) using content validation ratio (CVR) through Lawshe's formula. The feasibility of the module was tested on 10 subjects diagnosed with SPDs as per the International Classification of Diseases (ICD) -10 criteria using standard scales. RESULTS: In the finalized module, 70.83% (34 out of 48 items) of the practices were retained along with the modifications as suggested by the experts. Two practices were not found to be feasible (Trikonasana and Shalabhasana) and hence were removed from the final module. A significant reduction in pain severity was observed in the subjects after practising the yoga module for 2 weeks. The content validity index for the whole module (average of all CVRs) was 0.55. CONCLUSIONS: Ayoga module was developed for SPD. The content validity of the module was found to be good. The module was found safe and potentially useful for reducing pain severity in patients with SPD. Future studies should test the efficacy of the developed program through a randomized controlled clinical trial.

Yoga and schizophrenia-a comprehensive assessment of neuroplasticity: Protocol for a single blind randomized controlled study of yoga in schizophrenia.

INTRODUCTION: Schizophrenia is one of the most severe mental disorders with a prevalence of about 1% and a leading cause of disability among young adults. Pharmacotherapy is the mainstay in the management of schizophrenia. However, even with the best of medication, several problems like refractoriness, negative symptoms, frequent relapses, and cognitive impairments persist. METHODS: This is a randomized-controlled clinical study including patients from an urban tertiary hospital and a semi-urban community center, with a between-group, repeated-measures, longitudinal design. This study will recruit 160 patients with DSM 5 diagnosis of schizophrenia who are on stable medication for a minimum of 6 weeks; they will be randomly assigned into 2 arms viz., yoga therapy (YT), and treatment-as-usual (TAU) with 80 patients in each arm. Participants will undergo Clinical, Laboratory, and Radiological assessments at baseline and at intervals of 1 month, 3 months, and 6 months from the baseline. It is hypothesized that yoga will improve psychopathology and emotion processing, increase serum brain derived neurotrophic factor (BDNF) and plasma oxytocin levels and effect changes in cerebral activation in areas of the brain associated with schizophrenia. DISCUSSION: This study aims to measure the efficacy of a Yoga-based intervention as an adjunct in patients with schizophrenia as well as the mechanisms of these effects. TRIAL REGISTRATION: Registered retrospectively with Clinical Trial Registry - India (CTRI) with registration number CTRI/2017/08/009219.

Yoga: Balancing the excitation-inhibition equilibrium in psychiatric disorders.

Social behavioral disturbances are central to most psychiatric disorders. A disequilibrium within the cortical excitatory and inhibitory neurotransmitter systems underlies these deficits. Gamma-aminobutyric acid (GABA) and glutamate are the most abundant excitatory and inhibitory neurotransmitters in the brain that contribute to this equilibrium. Several contemporary therapies used in treating psychiatric disorders, regulate this GABA-glutamate balance. Yoga has been studied as an adjuvant treatment across a broad range of psychiatric disorders and is shown to have short-term therapeutic gains. Emerging evidence from recent clinical in vivo experiments suggests that yoga improves GABA-mediated cortical-inhibitory tone and enhances peripheral oxytocin levels. This is likely to have a more controlled downstream response of the hypothalamo-pituitary-adrenal system by means of reduced cortisol release and hence a blunted sympathetic response to stress. Animal and early fetal developmental studies suggest an inter-dependent role of oxytocin and GABA in regulating social behaviors. In keeping with these observations, we propose an integrated neurobiological model to study the mechanisms of therapeutic benefits with yoga. Apart from providing a neuroscientific basis for applying a traditional system of practice in the clinical setting, this model can be used as a framework for studying yoga mechanisms in future clinical trials.
