Schizophrenia is one of the most severe mental disorders. Despite significant advances in pharmacotherapy, treatment remains sub-optimal, with many patients having persisting deficits, especially in cognitive and social functioning. Yoga as a therapy has proven to be effective as a sole or additional intervention in psychiatric disorders such as depression and anxiety. Recently, there has been significant interest in the application of yoga therapy in psychosis and schizophrenia. To review a) the evidence for the use of yoga therapy in patients with schizophrenia b) studies which have been done in this area, c) the barriers for reaching yoga to patients, and d) future directions, an English language literature search of PubMed/MEDLINE, Google Scholar, and EBSCO as well as grey literature was done. Research reports have demonstrated the feasibility and efficacy of yoga as an add-on therapy in schizophrenia, particularly in improving negative symptomatology and social cognition. However, the biological underpinnings of this effect remain unclear, although there are some indications that hormones like oxytocin may contribute to the changes in social cognition.

   Introduction Top


Schizophrenia is among the most severe mental disorders. Close to 5 per 1000 individuals in general population are affected. It sets in early in one's productive years (late 2 nd decade). Only a minority of patients will have a remitting course. Majority (>60%) will have a relapsing course with or without severe deficits. Both sexes and all communities are affected. There is a strong genetic contribution, but drugs of abuse like cannabis and other stimulants can bring on the illness earlier in life and also make the outcome of treatment unsatisfactory. Schizophrenia patients end up with significant disability and therefore contribute to burden. Schizophrenia ranks among the top ten causes of disease-related burden in the age group of 15-44 globally. [1]

The symptoms are generally classified into positive (delusions, hallucinations and formal thought disorder) and negative (amotivation, anhedonia, emotional blunting and poor insight). In the recent years, clinicians recognized a third domain of reduced cognition. Patients may develop symptoms either acutely or insidiously. Over the course of the disease and with age, the positive symptoms lose their sharpness. Most patients remain with negative syndrome and defective cognition (defect state), which sets in early stages of the illness and does not respond well to medication. [2],[3] The progressive decline in performance is associated with overt behavior that disturbs thought, affect and perception. Gross cognitive state and sensorium are unaffected for most part of the disease. However, these patients are socially less sensitive and this social cognition deficit negatively influences functioning. [4],[5]

Schizophrenia cannot be diagnosed by a laboratory test. Apart from the clinical description, some diagnostic systems give emphasis to the duration of symptoms. One month to six months of symptomatic state is needed to assign a diagnosis of schizophrenia by ICD-10 [6] or DSM-IV. [7] In acute, first-time presentations, patients may need to undergo some investigations to rule out a possible neuropathological basis of the illness. Some common neurological conditions may present as schizophrenia-like psychosis, albeit rare. Investigations have unearthed some brain changes (enlarged ventricles and loss of grey matter) in schizophrenia patients early in the course of the illness. [8] This loss also progresses in some patients with neurodegenerative process. Environmental effects trigger a cascade of pathophysiology such as proinflammatory cytokines, reduced neuroplasticity and premature aging. Some scientists have also implicated the treating drugs as partly contributory to these processes.


Treatment of schizophrenia is challenging. Antipsychotic drugs of the first generation produced extrapyramidal side effects. The second generation drugs are related to worsening or causing obesity and dyslipidemia. A sizeable proportion of patients do not obtain remission or even satisfactory symptom-relief. Positive symptoms may show good response to drugs, whereas negative and also cognitive symptoms either fail to respond or even worsen with most of the antipsychotic therapies. [3] As a result patients may need cognitive remediation (a treatment still to emerge successfully). They may have attendant depressive symptoms as part of the disease or as a side effect of drugs, thus compounding the illness and disability thereof. A good proportion of patients develop secondary complications, clinical as well as psychosocial. Tardive extrapyramidal syndromes, metabolic syndromes, defect state, suicide attempts are a few of these. Patients are often non adherent to treatment. The caregivers face burden and develop significant burn out. Patients who do not remit generally end up in after-care homes. Divorce/separation is a common social complication.

Yoga as an add-on treatment in schizophrenia is thus conceived on the following rationale:

  1. Drugs used in the treatment of schizophrenia do not yield satisfactory results.
  2. Negative and cognitive symptoms almost always remain nonresponsive.
  3. Obesity and metabolic syndrome coexist with schizophrenia with or occasionally even without concurrent drug therapy.
  4. Patients develop endocrinological and menstrual dysfunction as a result of drugs.

Yoga has demonstrated success in improving cognition, has improved obesity as well as metabolic syndrome, helped in correcting menstrual disturbances and some other endocrine dysfunctions. It is in this context, a role for yoga has been conceived in the treatment of schizophrenia after medications produce their effects.

However, there were very few studies looking at the feasibility and efficacy of yoga therapy as an intervention in this, the most serious disorder treated by psychiatrists. There may be several reasons for this. Firstly, the concept of yoga as a therapy rather than lifestyle is not acceptable to many yoga purists/schools. Secondly, the feeling that patients with schizophrenia may not be able to perform all aspects of yoga, particularly the mental aspect, as recommended. Thirdly, the lack of insight and poor adherence to treatment in most patients may discourage researchers from recommending yoga to these patients.

   Methods and Literature Review Top

Fortunately, the last few decades have seen significant efforts in this direction, with several controlled studies with rigorous methodology being conducted in this population. However, many of these are not yet reflected in peer-reviewed literature. A recent meta analysis of the effectiveness of yoga as a complementary treatment for all psychiatric disorders [9] included only one randomized controlled trial in schizophrenia. Another systematic review of the benefits of physical therapy for people with schizophrenia [10] reported that yoga reduces psychiatric symptoms, state anxiety, and psychological distress and improve health-related quality of life, but that the heterogeneity of the interventions and the small sample sizes of the included studies limit overall conclusions. In this light, there is a need for a comprehensive review of yoga as an intervention in patients with psychosis (particularly schizophrenia). This is the focus of the current review. With this focus, relevant literature was obtained using the following methods: An English language literature search of PubMed/MEDLINE, Google Scholar, and EBSCO using the search terms 'Yoga AND Schizophrenia' and 'Psychosis AND yoga' as well as a direct search of reference list of pertinent journal articles. Information on manuscripts accepted and under review for publication in journals, as well as dissertations and project reports, was also solicited from centres where such research is ongoing, particularly in India.

Studies of yoga as a therapy in schizophrenia

Specific yoga packages for patients with psychosis have been derived based on the Panchakosha model. Most packages include some asanas and pranayama/breathing patterns but not meditative practices, since meditation has been shown to worsen/provoke psychosis in patients with psychosis. [11] A study by researchers at the Swami Vivekananda Yoga Anusandhana Samsthana (SVYASA) was probably the first to scientifically test such a package in chronically ill patients. In this study, institutionalized patients with schizophrenia were able to learn the yoga under supervision and the yogasana package produced some cognitive benefits in schizophrenia subjects without causing disturbing side effects. [12]

The same package was used in another study with 41 outpatients who remained on stabilized antipsychotic therapy but had modest deficit symptoms. These patients and their family members consented for this randomized study. There were two arms; one of which was a yogasana package, the other a set of physical exercises. Patients were trained for one month (at least 12 sessions) in each of these two by certified yoga instructors. The patients were advised to continue the practices at home for next three months. Telephonic reminders to patients or caregivers were used to encourage adherence. No change was made as regards their drug treatment. Patients' clinical state as well as social function was assessed at base line and at the end of the study (4 months) by a single psychiatrist uninvolved in treatment allocation. Patients knew to what group they belonged and therefore the study design was not entirely blind. [13]

In both groups negative syndrome score dropped over the four months. However, the yoga group performed better. Likewise, social dysfunction score too reduced over the four months and the yoga group obtained an advantage [Figure 1]. Positive symptoms had little scope in this sample for further improvement; yoga, naturally, did not confer any benefits on this account.

A recent randomized, controlled pilot study by Visceglia et al. included 18 clinically stable inpatients (12 males and 6 females) with schizophrenia residing at a state psychiatric facility. Out of them 10 patients were randomized to an eight-week supervised yoga program (2 sessions/week) and the rest were waitlisted.The yoga module included postures, breathing exercises, and relaxation. Psychopathology and quality of life was measured using the PANSS and WHOQOL-BREF respectively, at baseline and after 8 weeks. Subjects who received yoga therapy achieved significant improvements in psychopathology scores (PANSS total and subscale scores) and quality of life (physical and psychological domains). [14] In view of the small sample size, the authors have concluded that the results need confirmation from larger studies.

The above studiesmay be seen as preliminary, and confirmation with different objectives would be ideal: Some of the active research questions may be the following: (1) the observed benefits of either yoga or exercise must be compared with a waitlisted group, (2) cognitive measures in schizophrenia must also be obtained rather than mere clinical syndrome measurements, (3) benefits of yoga in acute inpatients with psychosis should be studied and (4) biological mechanisms of yoga in schizophrenia need to be investigated.

Waitlist-controlled randomized study

A recent study [15] extended the investigation of yoga efficacy in schizophrenia. Outpatients stabilized on antipsychotic medications without recent (three months) changes in medicines were contacted. Patients with a Clinical Global Impression - Severity rating of >3 were excluded. Among the rest, patients who were consenting to be randomized to this three-arm trial of yoga were included.

The design was prospective and randomized. In addition to yoga and exercise groups, there was a third waitlisted group for the 4 months of study. The sample size was estimated a priori. Giving margin for dropouts, a sample size of 120 patients (40 in each group) was considered adequate. To recruit 120 patients nearly ten times this number had to be interviewed. The reasons for this have been the subject of a different paper. [16] The therapist ensured that they attended at least 12 classes (or more) in the first month. Subjective judgment of learning yogasana well enough to be practiced at home was satisfactory in all patients. Family members were encouraged to motivate patients to adhere to the yoga/exercise sessions as regularly as possible in the next three months.

The patients were assessed on clinical symptoms, social function and a tool for social cognition. The rater was uninvolved in treatment allocation. The study was able to confirm the earlier findings. Yogasana helped in reductions of scores on negative syndrome significantly [Figure 2].

Pooled Data

The yoga and exercise groups in the above two studies [13],[15] were identical. Likewise, the two studies used similar assessment schedules. The pooled data from both studies was reanalyzed. The data confirmed the observed benefits of yoga in negative symptoms. The effect size was larger (article under review for publication). A large effect size is supportive of clinical effects of yoga therapy in negative syndrome.

Another connected study by the same group has been able to confirm the feasibility and effectiveness of yoga in improving symptoms of schizophrenia in a naturalistic crossover design. The waitlisted patients in the above quoted study [15] requested yoga after the study period. The patients had been assessed at the time of inclusion into the previous study as waitlist controls and the assessments had been repeated after one and three months. After the study period when they sought yoga therapy, their clinical states were assessed before and after one month's yoga therapy. [17] The benefits of yoga were demonstrable at the end of 1-month intervention.

Effect of yoga on social cognition

In the study by Gangadhar et al, [15] a social cognition test was performed at baseline and at the end of the study. This test measured the patient's ability to recognize facial emotions. The tool used is standardized with Indian patients - Tool for Recognition of Emotions in Neuropsychiatric Disorders (TRENDS). The score on the number of images emotions correctly recognized by the patients was obtained - TRENDS Accuracy Score (TRACS).

The patients in the yoga group had lower TRACS at baseline. The TRACS improved in the yoga group from baseline to 2 nd month as well as to the end of the study.The improvement in TRACS of yoga patients was significant [Figure 3]. No such significant change occurred in either exercise or waitlisted patients. [18]

One of the limitations of this study may be that by virtue of lower TRACS at baseline, the yoga group had a scope for improvement and hence significant results were obtained. Also, not all the randomized patients cooperated for this testing, which weakened the randomization effect. Perhaps a separate study to replicate/confirm these findings is necessary. There is also a need to extend this work to demonstrate if improvement in social cognition is accompanied by a demonstrable physiological change in the brain.

In the above studies of yoga in schizophrenia, the patients were selected from outpatient services and were on follow up for long periods. Most were ill for several years. Over decades of observations, psychiatrists have noted findings suggestive of irreversibility with time. In fact, treating the disease early (therefore reducing the duration of untreated psychosis), is well reported to predict a better outcome. Therefore, introducing yoga at a later stage of the disease may produce only limited effects. Also, the differential effect of adding yoga in the early stages of treatment is an important clinical question.

Yoga for inpatients acutely treated for psychosis

A pilot study of a short-term yoga module evaluated in-patients being treated for psychosis, including schizophrenia. Consecutive patients who were reaching a clinical state that was adequate to engage them in yogasana practices were approached. Consent from both the patient and the relative was obtained after adequate information. These patients continued to receive the antipsychotics prescribed by their treating team. Consenting patients who met these conditions in the wards were recruited into the study. The patients were randomized to receive additional yoga therapy sessions for the next two weeks or until discharge, the other group received physical exercise. Yoga was taught for first two weeks only and patients had to practice in the month of care at home.They were assessed by the same clinician before and after the 2-week trial as well as a month later.

After two weeks (n = 82), both groups obtained similar benefits without any difference between yoga and exercise. At the end of the next month (n = 60), clinical ratings again suggested comparable reduction in symptom scores between the two groups. However depression scores fell more steeply in the yoga group. [19]

Comparison between yoga and exercise in a cross-over trial

Cross-over design is a well-conceived standard practice in psychopharmacological research. Each individual has a propensity to get better and these 'individual-related' factors are taken care for in randomized trials. However, they cannot directly control for the time-effect. The course of the illness as well as expectation bias may have a confounding effect on the scores. Randomized cross over is an alternative in which two or more drugs can be compared in a within a diagnostic group. One of the treatments is given first for a pre-decided duration at the end of which the patient is crossed over to the other alternative. Therefore, the active and comparative treatments are applied to the same subject without/with subjects' knowledge. The blinding in the former case attends to the expectation effect. However, yoga is unique; the patient cannot be 'blinded'. The confounding factor of the natural course of the illness can be partly answered by the randomized cross over effect, viz., one group receives the test followed by control treatment, whereas the other randomized group will receive the control treatment followed by test treatment. While this is an ideal situation, it is not known if yoga effects end with stopping of practice. If not, what is the time interval before the benefits, if any, are lost?

Notwithstanding these limitations, a'naturalistic' cross over study has been attempted. In the recently completed 3-arm trial in schizophrenia [15] outpatients, the waitlisted patients were offered 1- month training of yoga at the end of the study if they wanted. Consent was sought if they can be systematically assessed on rating scales before and after one month of yoga therapy. Consenting patients (n = 14) were assessed like they were assessed when they were in the waitlisted group is the 3-arm trial.

The patients obtained no significant change in the scores of negative or positive syndrome in the 1 st month of waiting (nor after 3 more months of waiting). However, in the ratings obtained one month after active yogasana therapy, there was a significant reduction in their negative syndrome score but not in the positive. This suggests that the yoga actually produced clinical effects and that observed effects in earlier studies cannot be merely due to 'waiting'. [17]

Biological mechanisms of yoga therapy in schizophrenia

Well-being and quality of life have become better after yoga. Depression lifts, and social sensitivity, the ability to recognize emotions in others, improves. How does yoga effect this change?

A possible hypothesis is that oxytocin is involved in this change. Oxytocin has been labelled as the 'cuddling' hormone that is released with the feeling of wellbeing. Oxytocin release has been linked to vagal afferent stimulation from reproductive organs. Thus, a vagus afferent mechanism or yet another unexplained effect may be responsible for this sense of well-being. Oxytocin receptors have been implicated in effecting this behavioral change. Oxytocin analogues have, in fact, been suggested for treating schizophrenia. [20]

A recent study randomized schizophrenia patients to receive yoga or remained waitlisted for one month.The yoga package used in this study was the same as used and published in the paper by Duraiswamy et al. [13] Consenting patients who participated demonstrated significant benefits in emotional recognition (TRENDS scores) following yoga However, no such benefit was demonstrated in waitlisted subjects. Blood samples were collected before and after yoga or waitlist period. The samples were analyzed for oxytocin levels. Oxytocin levels rose significantly in yoga group, nearly threefold. No such change was evident in waitlisted group [Figure 4]. This supports the possibility that oxytocin elevations are caused by yoga. [21] This mechanism may explain the benefits in social cognition as well as the wellbeing effect following yoga.

Barriers for yoga therapy in psychiatric disorders

In the above detailed 3-arm yoga trial for schizophrenia, close to a thousand patients were screened in the outpatient clinics. 392 patients were suitable for the study and of these 223 could not participate in the study. The most important reason quoted by the patient/family for refusal was analyzed. In 83, it was the distance from the yoga service. In 25, 25 and 21 of them the reason was 'no one to bring the patient', 'agreed but did not come at all', and 'patient is going to work' respectively. Only nine did not want yoga and one gave a religious reason. 20% of patients offered no reason at all. [16]

This was an offshoot of observation in a hospital setting. Clearly, over 50% of patients suitable for yoga could not avail the same. Although unwillingness to participate in research/trial was not quoted as the most striking or important reason in any, it may be suspected that the 20% who did not give any reason but refused to participate in the study may have done so not wishing to go through research. Among the others who refused, the reasons were logistic, e.g., living far away, no one to accompany, employed/working patients. Very few did not want yoga.

How can these logistic barriers be reduced? Can yoga be reached closer to their residence? Can yoga be taught in a shorter period than one full month? For example, many patients with schizophrenia come for follow up once a month for medications or other interventions. Is it possible to develop a less conventional once a month training for schizophrenia patients? Lastly, mental hospitals and after-care homes may regularly provide supervised yoga therapy by a visiting instructor who may be employed for part or full time. Yoga-based, stand-alone or add-on treatments should be provided to the psychiatrically ill in the hospitals. Reaching this service to community-based patients is yet another challenge. National mental health programs must include this feature for the service of the mentally ill.

   Summary and Conclusions Top

Yoga as a therapy in psychosis, specifically schizophrenia, has been demonstrated to be feasible and effective as an add-on therapy. Most of the studies have used a combination of asanas and pranayama, avoiding meditation. The effects are multifaceted, including reduction of psychotic symptoms and depression, improving cognition, increasing quality of life, and producing neurobiological changes, such as increased oxytocin levels.

Further research is needed into the exact mechanisms of action of yoga in producing the above changes, as well as overcoming the barriers in reaching yoga to the majority of patients suffering from this devastating illness.
