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.

Impact of Technology Driven Mental Health Task-shifting for Accredited Social Health Activists (ASHAs): Results from a Randomised Controlled Trial of Two Methods of Training.

Mental health task shifting is a potential way to address the burgeoning treatment gap for mental illness. Easily available and accessible digital technology can be utilised to continuously engage grassroot level health workers (for example, Accredited Social Health Activists (ASHAs). However, the impact of such a strategy is not yet systematically evaluated. In this randomised controlled trial, longitudinal hybrid training of ASHAs [1 day in-person classroom training and seven online sessions (ECHO model), aimed to screen and refer to commonly prevalent mental health issues in communities] was compared with traditional one-day in-person classroom training. ASHAs (n = 75) from six Primary Health Centres in Ramanagara district, Karnataka, India were randomized into study (SG-ASHAs) and control (CG-ASHAs) groups. After excluding drop-outs, 26 ASHAs in each group were included in the final analysis of the scores on their Knowledge, attitude, and practices (KAP) in mental health. Two house-to-house surveys were conducted by both groups to identify and refer possible cases. The number of screen positives (potential persons with mental illnesses) and the KAP scores formed the outcome measures. Online sessions for SG-ASHAs were completed over 18 months, the COVID-19 pandemic being the main disruptor. SG-ASHAs identified significantly higher number of persons with potential alcohol use disorders [n = 873 (83%); p ≤ 0.001] and common mental disorders [n = 96(4%); p = 0.018], while CG-ASHAs identified significantly higher number of those with potential severe mental disorders [n = 61(61.61%); p ≤ 0.001]. As regards KAP, after controlling for baseline scores, the time effect in RMANOVA favoured SG-ASHAs. Mean total KAP score increased from 16.76 to18.57 (p < 0·01) in SG-ASHAs and from 18.65 to 18.84 (p = 0.76) in CG-ASHAs. However, the Time-group interaction effect did not favour either (F = 0.105; p = 0.748). Compared to traditional training, mentoring ASHAs for extended periods is more impactful. Easily accessible digital technology makes the latter feasible. Scaling up such initiatives carry the potential to considerably improve treatment access for those in need.

The rationale and guiding principles to design a psychiatry curriculum for primary care doctors of India.

Background Integrating psychiatric care into the general practice of primary care doctors (PCDs) is necessary to overcome the shortage of human resources to cater to the burgeoning public mental health needs of India. The traditional psychiatry curriculum is often top-down and specialist-based that contributes little in terms of skill quotient. We designed an innovative, digitally driven, distance education-based, part-time, modular-based Primary Care Psychiatry Programme (PCPP, skill-based). It is being implemented across many states of India to equip PCDs with skills to provide first-line psychiatry treatment. We discuss the rationale and guiding principles behind designing the curriculum of PCPP. Discussion There are nine guiding principles behind designing and implementing PCPP to provide pragmatic, acceptable, feasible modules of higher translational quotient (TQ) that are essential to upskill PCDs. There is a shift in training the location of PCDs in their live brief general consultations utilizing innovative telemedicine-based 'on-consultation training' (OCT) augmented with collaborative video consultations. A monolithic treatment protocol-driven, trans-diagnostic approach is used to design a concise, all-inone, point-of-care manual containing a culturally sensitive, rapid, validated screener and taxonomy, called 'Clinical Schedules for Primary Care Psychiatry'. This incorporates the PCDs' style of clinical practice that helps in picking up the most commonly prevalent adult psychiatric disorders presenting to primary care. Conclusion This PCPP curriculum contains pragmatic modules with higher TQ. This curriculum is dynamic as the learning is bi-directional. This can be used by policy-makers, innovators and academia for integration with national health programmes such as those for non-communicable diseases and reproductive and child health.

Care at Doorsteps for Persons with Severe Mental Illnesses as a Part of District Mental Health Program (DMHP): A Qualitative Needs Assessment and Psychosocial Framework.

Care at Doorstep (CAD) is a home care service that includes medical and social care by skilled professionals. The purpose of this paper is to explore the need for CAD among users of the district mental health programme (DMHP) in Ramanagaram, Karnataka, India who have severe mental illness. The design of this study was descriptive where a qualitative inductive methodology was adopted. Data was collected from interviews of 20 caregivers and 7 mental health service providers linked to the DMHP. Socio demographic information was collected from participants and a semi-structured interview guides were used to explore needs and challenges in delivering care at home by the professionals. The themes that emerged from the manually transcribed and coded data were categorized as needs and challenges and used for developing a CAD model.

Video consultations from an Indian academic hospital: First 3 years of experience from telepsychiatric after-care clinic.

Background Continuity of care for psychiatric disorders by conventional in-person consultation by psychiatrists is associated with several challenges. There is a need to develop alternative models of specialist care. We studied our 3 years' experience of live video consultations (VCs) from the tele after-care clinic to patients with psychiatric disorders at an Indian academic hospital. Methods We did a file review of 669 VCs provided to 213 patients in the first 3 years (2017-2019) from the telemedicine centre of a tertiary care academic hospital. We analysed details of sociodemography, clinical profile, tele after-care consultations and outcome. Results Two hundred and thirteen patients (55% men) were enrolled for the tele after-care clinic. The mean (SD) age of the patients was 42.2 (17.29) years and a majority were educated till high school and beyond. Patients with severe and common mental disorders constituted 60.1% and 40%, respectively. Among the total 669 appointments, 542 (81%) VCs were successfully provided; of the remaining, 125 were cancelled and 2 were aborted due to a medical emergency. Medication prescriptions were unchanged in 499 and modified/totally changed in 47 VCs. Conclusion Our large study shows that telepsychiatric after-care is a useful alternative method which can supplement in-person follow-up. Barriers such as distance, cost and medical illness can be overcome using tele after-care clinics for regular follow-ups in stabilized psychiatric patients. There is a need for prospective studies, preferably, randomized controlled trials comparing effectiveness of tele after-care with in-person consultations to assess treatment outcomes.

Embracing Technology for Capacity Building in Mental Health: New Path, Newer Challenges.

Technology driven capacity building initiatives are the way to break the barrier of shortage of mental health human resources in India. This new path, while is a welcome step, comes with its own set of challenges. In one prototypic project that is being implemented in Ramanagara District of Karnataka, a south Indian state, we encountered many such issues. They ranged from issues related to availability of dedicated space to set up the hub-studio, inconsistent internet connectivity (particularly in remote areas) and inadequate digital literacy among the grassroot community health workers who hail from villages. This article summarises these challenges and ends by looking into ways and means of overcoming them.

Identification of Psychiatric Disorders by Rural Grass-Root Health Workers: Case Series & Implications for the National Mental Health Program of India.

Auxiliary Nurse Midwife (ANMs) and Accredited Social Health Activists (ASHAs) are well suited to cater to the mental health needs of the communities. Integrating primary mental health care into the general healthcare is one of the important objectives of the District Mental Health Program (DMHP) to reduce the treatment gap. As a part of an ICMR funded trial to evaluate the effectiveness of NIMHANS-ECHO blended training program, the ASHAs and ANMs were trained to identify and refer cases from the community. We aim to describe a series of cases identified by those workers from the community, highlighting their importance in our health care system.

Elevated mirror neuron system activity in bipolar mania: Evidence from a transcranial magnetic stimulation study.

OBJECTIVES: The role of the "mirror neuron system" (MNS) in the pathophysiology of mood disorders is not well studied. Given its posited role in the often-impaired socio-emotional processes like intention detection, empathy, and imitation, we compared putative MNS-activity in patients with bipolar mania and healthy comparison subjects. We also examined the association between putative MNS-activity and hyper-imitative behaviors in patients. METHODS: We studied 39 medication-free individuals diagnosed with mania and 45 healthy comparison subjects. TMS-evoked motor cortical reactivity was measured via single- and paired-pulse stimuli (assessing SICI-short and LICI-long interval intracortical inhibition) while subjects viewed a static image and goal-directed actions. Manic symptom severity and imitative behaviors were quantified using the Young's Mania Rating Scale and a modification of the Echolalia Questionnaire. RESULTS: Two-way repeated measures analysis of variance demonstrated a significant group ×time interaction effect indicating greater facilitation of cortical reactivity during action-observation (putative MNS-activity) in the patient group as compared to the healthy group. While LICI-mediated MNS-activity had a significant association with manic symptom severity (r = 0.35, P = 0.038), SICI-mediated MNS-activity was significantly associated with incidental echolalia scores in a subgroup of 17 patients with incidental echolalia (r = 0.75, P < 0.001). CONCLUSIONS: Our findings demonstrate that putative MNS-activity is heightened in mania, possibly because of disinhibition, and associated with behavioral consequences (incidental echolalia).

Investigational and Therapeutic Applications of Transcranial Magnetic Stimulation in Schizophrenia.

PURPOSE OF REVIEW: This current review summarizes the investigational and therapeutic applications of transcranial magnetic stimulation (TMS) in schizophrenia. RECENT FINDINGS: Fairly consistent findings of an impaired cortical excitation-inhibition balance, cortical plasticity, and motor resonance have been reported in schizophrenia. Cortical connectivity impairments have also been demonstrated in motor and prefrontal brain regions. In terms of treatment, the best support is for 1-Hz TMS to the left temporoparietal cortex for the short-term treatment of persistent auditory hallucinations. High-frequency TMS to the left prefrontal cortex improves negative and cognitive symptoms, but with inconsistent and small effects. TMS combined with diverse brain mapping techniques and clinical evaluation can unravel critical brain-behavior relationships relevant to schizophrenia. These provide critical support to the conceptualization of schizophrenia as a connectopathy with anomalous cortical plasticity. Adaptive modulation of these aberrant brain networks in a neuroscience-informed manner drives short-term therapeutic gains in difficult-to-treat symptoms of schizophrenia.

Discovery biology of neuropsychiatric syndromes (DBNS): a center for integrating clinical medicine and basic science.

BACKGROUND: There is emerging evidence that there are shared genetic, environmental and developmental risk factors in psychiatry, that cut across traditional diagnostic boundaries. With this background, the Discovery biology of neuropsychiatric syndromes (DBNS) proposes to recruit patients from five different syndromes (schizophrenia, bipolar disorder, obsessive compulsive disorder, Alzheimer's dementia and substance use disorders), identify those with multiple affected relatives, and invite these families to participate in this study. The families will be assessed: 1) To compare neuro-endophenotype measures between patients, first degree relatives (FDR) and healthy controls., 2) To identify cellular phenotypes which differentiate the groups., 3) To examine the longitudinal course of neuro-endophenotype measures., 4) To identify measures which correlate with outcome, and 5) To create a unified digital database and biorepository. METHODS: The identification of the index participants will occur at well-established specialty clinics. The selected individuals will have a strong family history (with at least another affected FDR) of mental illness. We will also recruit healthy controls without family history of such illness. All recruited individuals (N = 4500) will undergo brief clinical assessments and a blood sample will be drawn for isolation of DNA and peripheral blood mononuclear cells (PBMCs). From among this set, a subset of 1500 individuals (300 families and 300 controls) will be assessed on several additional assessments [detailed clinical assessments, endophenotype measures (neuroimaging- structural and functional, neuropsychology, psychophysics-electroencephalography, functional near infrared spectroscopy, eye movement tracking)], with the intention of conducting repeated measurements every alternate year. PBMCs from this set will be used to generate lymphoblastoid cell lines, and a subset of these would be converted to induced pluripotent stem cell lines and also undergo whole exome sequencing. DISCUSSION: We hope to identify unique and overlapping brain endophenotypes for major psychiatric syndromes. In a proportion of subjects, we expect these neuro-endophenotypes to progress over time and to predict treatment outcome. Similarly, cellular assays could differentiate cell lines derived from such groups. The repository of biomaterials as well as digital datasets of clinical parameters, will serve as a valuable resource for the broader scientific community who wish to address research questions in the area.

Augmentation Effect of Low-Frequency Repetitive Transcranial Magnetic Stimulation Over Presupplementary Motor Area in Obsessive-Compulsive Disorder: A Randomized Controlled Trial.

OBJECTIVE: The current study investigated the efficacy of low-frequency repetitive transcranial magnetic stimulation (rTMS) over bilateral presupplementary motor area (pre-SMA) in patients suffering from obsessive-compulsive disorder (OCD) with partial/poor response to pharmacotherapy, in a double-blinded randomized sham controlled trial. METHOD: Forty subjects with OCD, who were on stable medications with partial/poor response to pharmacotherapy were randomly divided into 2 groups (n = 20 in each group), to receive either active or sham low-frequency rTMS over bilateral pre-SMA. Thirty-six patients were eligible for intent-to-treat analysis. There was no significant difference in relevant demographic and clinical variables between the 2 groups at baseline. RESULTS: There were no statistically significant differences between the 2 groups after 3 weeks of treatment in the Yale-Brown Obsessive Compulsive Scale score (time*group interaction, F2.48,84.16 = 0.80, P = 0.40) and other secondary outcome measures including responder rates and depressive and anxiety symptoms. CONCLUSIONS: Low-frequency rTMS over pre-SMA may not be effective as an augmenting agent in partial/poor responders to SRIs. This study underlines the need to explore alternate rTMS protocols in OCD.

Duration of Pupillary Unresponsiveness to Light: A Physiological Adjunct to Electroencephalography and Motor Seizure Duration Monitoring During Electroconvulsive Therapy.

BACKGROUND: During electroconvulsive therapy (ECT) sessions, we observed that the time taken for the return of pupillary response to light (ROPL) outlasted both the electroencephalography (EEG) and the motor seizure duration after the delivery of the electrical stimulus to produce convulsions. OBJECTIVE: The objective of this study was to investigate whether ROPL can be used as a marker of cessation of seizure activity in the brain after ECT and also to study the effect of atropine premedication on seizure activity during ECT. METHODS: Forty-one patients underwent 82 sessions of ECT in a cross-over design study. The duration of motor seizure, EEG seizure, and time for ROPL was observed and compared. RESULTS: The ROPL consistently outlasted EEG and motor seizures; the difference in their mean durations was statistically significant P < 0.05. There was good correlation among the 3 parameters. Atropine premedication did not alter the seizure activity and ROPL after ECT. CONCLUSIONS: The ROPL after ECT stimulus is a good bedside monitor for termination of seizure activity and can be a valuable adjunct to surface EEG in monitoring the duration of epileptic activity after delivery of ECT.

Cortical inhibition in symptomatic and remitted mania compared to healthy subjects: A cross-sectional study.

OBJECTIVES: Transcranial magnetic stimulation (TMS)-derived cortical reactivity studies provide a unique opportunity to non-invasively study gamma amino butyric acid (GABA)-mediated inhibitory neurotransmission in bipolar disorder (BD). Earlier studies were conducted in smaller samples and on patients who were on medications that can potentially confound the results. We aimed to study short-interval (SICI) and long-interval intracortical inhibition (LICI) in medication-naïve/free symptomatic (manic) BD patients (n=39), first episode mania (FEM) patients who had recently (≤6 months) remitted with treatment (remitted FEM; n = 28) and healthy subjects (HSs; n = 45). METHODS: Resting motor threshold (RMT), stimulation intensity to elicit a 1-mV motor evoked potential (MEP) (SI1 mV ), SICI and LICI were measured in three groups using single- and paired-pulse TMS. RESULTS: Motor thresholds were higher in the manic BD and HS groups compared to the remitted FEM group (P < .001). SICI was lower (P = .026) but LICI was higher (P = .044) in the manic BD and remitted FEM groups compared to the HS group. CONCLUSIONS: Lower motor thresholds in remitted FEM perhaps reflect the effect of treatment, and could be studied as potential prognostic neuromarkers. Inverse findings for SICI (reduced) and LICI (increased) in BD indicate a possible differential involvement of the GABAA and GABAB subreceptor systems. These could be trait markers as they are impaired in both mania and euthymia.

Antipsychotic treatment, psychoeducation & regular follow up as a public health strategy for schizophrenia: Results from a prospective study.

BACKGROUND & OBJECTIVES: In low- and middle-income countries such as India, a feasible public health strategy could be to ensure continuous antipsychotics and psychoeducation for those with schizophrenia. Whether such a strategy favourably influences its course and outcome is not well-studied. The objectives of this study were to examine these issues in a cohort of patients with schizophrenia in a rural south Indian taluk (an administrative block). This cohort was part of a community intervention programme running in the place since the past one decade. METHODS: A total of 201 patients were assessed after an average of four years of follow up. Psychopathology, disability and course of illness were assessed using Positive and Negative Syndrome Scale (PANSS), Indian Disability Evaluation and Assessment Scale (IDEAS) and Psychiatric and Personal History Schedule (PPHS), respectively. Interventions included ensuring continuous antipsychotic treatment and low-intensity psychoeducation. RESULTS: One hundred and forty two [70.6%; 95% confidence interval (CI): 64.35-76.95] of the 201 patients achieved clinical remission by the end of follow up period (four years); 140 (69.6%; 95% CI: 63.29-76.07) had satisfactory outcome (42.3% best outcome and 27.4% intermediate outcome). There was a significant reduction in the proportion of patients with disability [134/201 (66.7%) at baseline; 55/201 (27.3%) at follow up; PInterpretation & conclusions: Treatment with antipsychotics and psychoeducation can favourably influence the course of schizophrenia and reduce disability in a substantial proportion of patients. Structured psychosocial interventions may be indicated in the significant minority who show suboptimal outcome with this strategy.

Concomitant Anticonvulsants With Bitemporal Electroconvulsive Therapy: A Randomized Controlled Trial With Clinical and Neurobiological Application.

BACKGROUND: Electroconvulsive therapy (ECT) is an effective treatment for major affective disorders. The combined use of ECT and anticonvulsant mood stabilizers is a common clinical scenario. There is dearth of systematic studies on the use of this combination with regard to clinical or cognitive outcomes. OBJECTIVE/HYPOTHESIS: We aimed to compare clinical improvement and cognitive adverse effects between patients who received only ECT versus those who received ECT and anticonvulsants. We hypothesized that improvement would be fastest in patients who received only ECT. METHODS: We conducted a randomized controlled trial in which patients prescribed ECT while being treated with anticonvulsants were randomized into 3 groups: full-dose (FD), half-dose (HD), and stop anticonvulsant. A blind rater assessed clinical improvement in patients using rating scales [Young's Mania Rating Scale (YMRS) and Clinical Global Impression] for clinical improvement and cognitive adverse effects (Postgraduate Institute memory scale). Analysis was done using mixed-effects modeling to delineate differences in clinical and cognitive outcomes across the 3 arms of the study over the course of ECT. RESULTS: Of the 54 patients recruited, 36 patients went into treatment allocation arms per the initial randomization plan. The main anticonvulsants prescribed were sodium valproate and carbamazepine. Patients in the 3 groups were comparable on clinical features. The most common diagnosis was bipolar affective disorder-with current episode of mania. Overall, there was no difference across the 3 groups in final clinical outcome scores (YMRS and Clinical Global Impression) when analyzed as intention to treat (ITT) or "as treated." In both analyses, group × time interaction was significant when comparing trend of YMRS scores between the FD anticonvulsant group and the HD group from baseline to last ECT (P = 0.0435 in ITT and P = 0.0055 in as treated). Patients in the FD group improved faster than those in the HD group. There were no differences across the 3 groups with regard to their cognitive adverse effects in the ITT analysis; "as-treated analysis" showed the HD patients to have performed poorly on some domains. Seizure parameters showed no significant difference across the 3 groups. CONCLUSION: This is a preliminary prospective study examining whether coprescription of anticonvulsants with ECT affected clinical or cognitive outcomes. The most important takeaway point from this study is the significant reduction in YMRS scores when ECT was given with FD anticonvulsant compared with halving the dose (HD) of anticonvulsant. This difference was shown in both ITT and as-treated analysis. There is a need for more prospective studies to examine this clinical question.

Effect of Atropine Premedication on Cardiac Autonomic Function During Electroconvulsive Therapy: A Randomized Crossover Study.

OBJECTIVES: Electroconvulsive therapy (ECT) results in significant cardiovascular changes. The acute cardiac autonomic changes during ECT remain unexplored. The primary objective of this study was to compare autonomic dysfunction with and without atropine premedication during ECT and secondarily to evaluate dysautonomia across psychiatric diagnoses before and after ECT. METHODS: In this crossover study, 41 psychiatric patients were monitored during 82 ECT sessions. Patients were randomized either to receive atropine or not to receive atropine during their second ECT session and were crossed over during their third session. Heart rate, blood pressure, and oxygen saturation were continuously monitored from stimulus application until 300 seconds after ECT. Demographic characteristics and ANSiscope indices derived pre- and post-ECT were collected. RESULTS: Autonomic dysfunction (%) before ECT was similar between atropine and no-atropine sessions (32.4 ± 15.7 vs 32.8 ± 16.7; 95% confidence interval, -7.6 to 6.7; P = 0.90) but increased significantly after ECT to 60.9 ± 16.3 and to 47.0 ± 17.3, respectively, and this difference was significant (95% confidence interval, 6.5-21.3; P < 0.001). There was no difference in the autonomic function across psychiatric diagnoses both before (P = 0.07) and after ECT (P = 0.12). CONCLUSIONS: Cardiac autonomic dysfunction worsens after ECT in patients with psychiatric illnesses and to a significantly greater extent with atropine premedication. The degree of dysautonomia is similar across various psychiatric diagnoses both before and after ECT. Atropine premedication during ECT should be restricted to select patients susceptible to bradyarrhythmia and could be avoided in others.

Serum cortisol and BDNF in patients with major depression-effect of yoga.

Depression is associated with low serum Brain Derived Neurotrophic Factor (BDNF) and elevated levels of serum cortisol. Yoga practices have been associated with antidepressant effects, increase in serum BDNF, and reduction in serum cortisol. This study examined the association between serum BDNF and cortisol levels in drug-naïve patients with depression treated with antidepressants, yoga therapy, and both. Fifty-four drug-naïve consenting adult outpatients with Major Depression (32 males) received antidepressants only (n = 16), yoga therapy only (n = 19), or yoga with antidepressants (n = 19). Serum BDNF andcortisol levels were obtained before and after 3 months using a sandwich ELISA method. One-way ANOVA, Chi-square test, and Pearson's correlation tests were used for analysis. The groups were comparable at baseline on most parameters. Significant improvement in depression scores and serum BDNF levels, and reduction in serum cortisol in the yoga groups, have been described in previous reports. A significant negative correlation was observed between change in BDNF (pre-post) and cortisol (pre-post) levels in the yoga-only group (r = -0.59, p = 0.008). In conclusion, yoga may facilitate neuroplasticity through stress reduction in depressed patients. Further studies are needed to confirm the findings and delineate the pathways for these effects.

Repetitive Transcranial Magnetic Stimulation Over Presupplementary Motor Area May Not Be Helpful in Treatment-Refractory Obsessive-Compulsive Disorder: A Case Series.

BACKGROUND: A significant proportion of patients with obsessive-compulsive disorder (OCD) fail to improve with standard medication and cognitive behavior therapy. Repetitive transcranial magnetic stimulation (rTMS) has been investigated for its role in treating OCD. Low-frequency rTMS over the presupplementary motor area (pre-SMA) has shown mixed results. Moreover, it has not been studied in highly treatment refractory OCD. We analyzed the outcome of low-frequency rTMS over pre-SMA in OCD patients refractory to multiple serotonin reuptake inhibitors (SRIs), augmenting agents, and cognitive behavior therapy. METHODS: Low-frequency (1-Hz stimulus at 100% motor threshold) rTMS was delivered over the pre-SMA using a previously described protocol. At least 25% reduction Yale-Brown Obsessive Compulsive Scale scores and 2-point reduction in Clinical Global Impression-Severity of Illness scores were used to assess treatment response. RESULTS: Seventeen patients were initiated on rTMS. Three of them dropped out within 9 sittings. Only 1 patient met the criteria for response after 1 month of treatment initiation. No major adverse effects were observed in any of them. LIMITATIONS: The study is a retrospective analysis of outcomes when rTMS was administered as part of routine clinical care. Assessments of the patients were done by trained but different raters, and interrater reliability was not measured. CONCLUSIONS: Low-frequency rTMS over the pre-SMA may not be effective in treatment refractory OCD. Further studies, taking note of the possible reasons for ineffectiveness discussed in the study, may help elucidate the role of rTMS in OCD.

Incidence and risk factors for oxygen desaturation during recovery from modified electroconvulsive therapy: A prospective observational study.

BACKGROUND AND AIMS: Electroconvulsive therapy (ECT) is an established modality of treatment for severe psychiatric illnesses. Among the various complications associated with ECT, oxygen desaturation is often under reported. None of the previous studies has evaluated the predictive factors for oxygen desaturation during ECT. The objective of this study was to evaluate the incidence of oxygen desaturation during recovery from anesthesia for modified ECT and evaluate its risk factors in a large sample. MATERIALS AND METHODS: All patients aged above 15 years who were prescribed a modified ECT for their psychiatric illness over 1 year were prospectively included in this observational study. The association between age, body mass index (BMI), doses of thiopentone and suxamethonium, stimulus current, ECT session number, pre- and post-ECT heart rate and mean arterial pressure, seizure duration, and pre- and post ECT oxygen saturation, was systematically studied. RESULTS: The incidence of oxygen desaturation was 29% (93/316 patients). Seizure duration and BMI were found to be significantly correlated with post ECT desaturation. CONCLUSION: In this prospective observational study, the incidence of oxygen desaturation during recovery from anesthesia for ECT was high. The study identified obesity and duration of seizure as the independent predictors of this complication. This knowledge is likely to help in identifying and optimizing such patients before subsequent ECT sessions.
