Yoga therapy as an add-on treatment in the management of patients with schizophrenia – a randomized controlled trial

Objective:  Treatment of schizophrenia has remained unsatisfactory despite the availability of antipsychotics. This study examined the efficacy of yoga therapy (YT) as an add‐on treatment to the ongoing antipsychotic treatment.

Automated MRI parcellation study of regional volume and thickness of prefrontal cortex (PFC) in antipsychotic-naïve schizophrenia.

Objective:  Prefrontal cortical dysfunction is considered to be critical in the pathogenesis of schizophrenia. However, structural magnetic resonance imaging (MRI) studies on the PFC have yielded inconsistent results because of various confounding factors.

A survey of the practice of electroconvulsive therapy in Asia.

Objective: To describe a comprehensive survey of the practice of electroconvulsive therapy (ECT) in Asia. Method: Between 2001 and 2003, a 29-item questionnaire was sent to 977 psychiatric facilities in 45 Asian countries. Results: Completed questionnaires were returned by 334 (34.2%) institutions in 29 (64.4%) countries. Electroconvulsive therapy was available in 257 institutions in 23 countries. During the year before the survey, 39,875 patients (62% men) received a mean of 7.1 ECT treatments. Most patients (73.1%) were 18 to 44 years old; few were younger than 18 years (6.0%) or older than 64 years (4.4%). Indications for ECT were schizophrenia (41.8%), major depression (32.4%), mania (14.0%), catatonia (6.9%), drug abuse (1.8%), dysthymia (1.6%), and others. Brief-pulse ECT devices were used in only 115 (58.4%) of 197 institutions. Routine electroencephalographic monitoring was conducted in only 59 (23.0%) institutions. Bilateral electrode placement was invariable in 202 (78.6%) institutions. Unmodified ECT was administered to 22,194 (55.7%) patients at 141 (54.9%) institutions in 14 countries. Continuation ECT was available in only 115 (44.7%) institutions in 17 countries. No institution had a formal ECT training program. Conclusions: The practice of ECT in Asia may seem suboptimal: schizophrenia, not depression, is the most common indication; most institutions offer sine-wave ECT; unmodified ECT is commonly administered; bilateral electrode placement is invariable in most institutions; electroencephalographic monitoring is uncommon; continuation ECT is infrequent; and no formal training in ECT is available. We speculate that the suboptimal practices reflect felt needs and ground realities in standards of medical care in developing countries rather than a misuse of ECT.

Survey of the practice of electroconvulsive therapy in teaching hospitals in India

Objectives: We sought to obtain an overview of electroconvulsive therapy (ECT) practice in teaching hospitals in India. Method: From September 1, 2001, to August 31, 2002, a 29-item questionnaire enquiring about ECT practice during the past year was sent to 188 teaching institutions and psychiatric hospitals. Results: Seventy-four institutions (39.4%) completed the questionnaire. ECT was available in 66 institutions. A total of 19,632 patients received 114,111 instances of ECT from 316 psychiatrists, of which 13,891 patients (70.8%) received 89,475 treatments (78.4%) from 128 psychiatrists in the psychiatric hospitals. The male-to-female ratio was 1.56 to 1. Brief-pulse device was used in 39 institutions. EEG monitoring was used routinely in only 8 institutions. Bilateral ECT was used in almost all institutions. Patients with schizophrenia received ECT most frequently (36.5%), followed by patients with major depression (33.5%), mania (17.9%), catatonia (6.2%), and dysthymia (2.8%). Patients who received ECT were in age group of 45-64 years (43.9%), followed by 25-44 years (34.5%), 65 years and older (14.7%), 18-24 years (5.6%), and younger than 18 years (1.4%). A total of 10,234 patients (52%) received unmodified ECT 52,450 treatments (46%) at 33 institutions. There was one case of ECT-related death during a survey. Continuation ECT was performed in 29 institutions and maintenance ECT in 17. Conclusions: More than 70% of ECT administrations in India were performed in the psychiatric hospitals. Approximately half of ECT use was unmodified ECT. The majority of patients who received ECT were diagnosed with schizophrenia and major depression. ECT training programs for psychiatry residents were acceptable.

The Social Occupational Functioning Scale (SOFS): A brief measure of functional status in persons with schizophrenia

The social functioning of persons with schizophrenia contributes to their overall functional outcome and ability to live in the community. Enhancing the level of social functioning is an important treatment goal. The present study describes the development of the Social Occupational Functioning Scale (SOFS), a brief, yet comprehensive, easy to administer measure of social functioning for use in busy clinical settings. It has adequate psychometric properties in terms of reliability and validity. Exploratory factor analysis revealed a three-factor structure comprising of adaptive living skills, social appropriateness and interpersonal skills, accounting for 59% of the variance in total SOFS score.

Sex difference in age at onset of schizophrenia: discrepant findings from India.

Consecutive male (n=100) and female (n= 100) DSM‐IV schizophrenics newly registered for treatment in a large psychiatric hospital were examined with regard to age at onset of the first psychotic symptom. Age at onset of the first psychotic symptom did not differ between the sexes regardless of whether schizophrenia was diagnosed by DSM‐IV or by several alternative systems. Age at onset defined by other criteria, namely age at first contact with a physician, and age at first admission for psychiatric care, also did not show any differences between the sexes. Survival analysis of subjects having a documented date of birth revealed a female preponderance at younger ages. A higher positive symptom score predicted older age at onset of the first psychotic symptom in the total sample. These findings call into question the universality of the traditional view of a younger age at onset of schizophrenia among males. Tentative neurodevelopmental and cultural explanations are presented to explain why there is no sex difference in age at onset of schizophrenia in India.

Prospective comparison of course of disability in antipsychotic-treated and untreated schizophrenia patients.

Objective:  To compare the course of disability in schizophrenia patients receiving antipsychotics and those remaining untreated in a rural community.

Therapeutic efficacy of add-on yogasana intervention in stabilized outpatient schizophrenia: Randomized controlled comparison with exercise and waitlist.

Background: Schizophrenia is a highly disabling illness. Previous studies have shown yoga to be a feasible add-on therapy in schizophrenia. Aims: The current study aimed to test the efficacy of yoga as an add-on treatment in outpatients with schizophrenia. Settings and Design: The study done at a tertiary psychiatry center used a single blind randomized controlled design with active control and waitlist groups. Materials and Methods: Consenting patients with schizophrenia were randomized into yoga, exercise, or waitlist group. They continued to receive pharmacological therapy that was unchanged during the study. Patients in the yoga or exercise group were offered supervised daily procedures for one month. All patients were assessed by a blind rater at the start of the intervention and at the end of 4 months. Results: Kendall tau, a nonparametric statistical test, showed that significantly more patients in the yoga group improved in Positive and Negative Syndrome Scale (PANSS) negative and total PANSS scores as well as social functioning scores compared with the exercise and waitlist group. Odds ratio analysis showed that the likelihood of improvement in yoga group in terms of negative symptoms was about five times greater than either the exercise or waitlist groups. Conclusion: In schizophrenia patients with several years of illness and on stabilized pharmacological therapy, one-month training followed by three months of home practices of yoga as an add-on treatment offered significant advantage over exercise or treatment as usual. Yoga holds promise as a complementary intervention in the management of schizophrenia.
