Background: Family caregivers provide essential support to their loved ones with schizophrenia with profound outcomes for themselves. The caregiver burden fails to consider the entire caregiving experience, which also incorporates positive aspects of caring. Many potentially significant variables are associated with this., Aim: To examine the correlates of the experience of caregiving in caregivers of patients with schizophrenia. The specific objectives were to examine the socio-demographic variables of the patients and caregivers, clinical variables of the patient, caregivers' knowledge of illness, caregivers' perspectives of family functioning, caregiver coping, their social support, psychological distress, quality of life, and their spirituality, religiosity and personal beliefs and the associations of these variables with the caregivers' experience of caregiving., Methods: This cross-sectional observational study was conducted between August 2018 and January 2021 at All India Institute of Medical Sciences, New Delhi, India. One hundred and fifty-eight dyads of patients with schizophrenia and their family caregivers were recruited using purposive sampling. Experience of Caregiving Inventory was used to evaluate the caregiving experience. The caregivers were also assessed on socio-demographics, knowledge of illness, family functioning, coping, social support, general mental health, quality of life, and spiritual, religious, and personal beliefs. Patient socio-demographics and clinical variables were also assessed., Results: A negative experience of caregiving was reported by caregivers of patients who had higher positive or negative symptoms of schizophrenia. Impaired Communication, Roles, Affective Responsiveness, Affective Involvement, and General Functioning aspects of family functioning were associated with a negative experience of caregiving. Denial/blame and seeking social support as coping were also associated with a negative experience of caregiving. A negative experience of caregiving was significantly positively correlated with greater psychological distress and poorer quality of life. Greater inner peace was associated with a less negative experience of caregiving. Spiritual strength was associated with a more positive experience of caregiving. Knowledge of mental illness and caregiver social support were not significantly associated with the experience of caregiving., Conclusion: Experience of caregiving is a relevant construct, the understanding of which can help inform caregiver-directed interventions in the future. Specifically, family-based interventions, which include ameliorating patient symptomatology, improving the family environment, strengthening caregivers' coping strategies, attending to caregiver distress, and encouraging spirituality among caregivers, may lead to a less negative and more positive experience of caregiving; and a better quality of life for caregivers., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Kochhar et al.)

Background and Aims: Caring for a person with schizophrenia entails considerable effort. The caregiving experience while caring for a person with schizophrenia has been described as both stressful and enriching. The literature on changes in caregiving experience with time has been fairly limited. The present analysis looks at the change in the caregiving experience of caregivers of patients with schizophrenia., Method: This study had a sample of 50 caregivers of patients with schizophrenia who were followed up after a period of 6 to 10 months. Caregiving experience, knowledge of the mental illness, family functioning, coping, social support, psychological distress, quality of life, and spiritual, religious, and personal beliefs were assessed at the two time points., Results: Among the negative caregiving experiences, caregivers' need for back-up and patient dependency reduced significantly at follow-up as compared to baseline, though total negative or positive experiences of caregiving did not show a significant difference. Knowledge about mental illness did not significantly increase at follow-up, though issues related to poor communication and affective involvement in family functioning reduced over the period of time. Coping and social support remained largely the same, while psychological distress was reduced. All domains of quality of life improved over the follow-up period, while the hope, optimism, and inner peace aspects of spiritual, religious, and personal beliefs improved with time., Conclusion: Some aspects of caregiving experiences may change with time. As caregivers become more adjusted to caregiving roles, their distress may reduce, and their quality of life may improve., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Kochhar et al.)

Background: Brain-derived neurotrophic factor (BDNF) has considerable relevance in neural growth and differentiation. It has been evaluated as a biomarker for individuals with various psychiatric disorders such as substance-related disorders and psychotic disorders., Objective: The present study explored differences in the levels of BDNF (in serum) among subjects using cannabis (with and without schizophrenia)., Methods: This cross-sectional observational study compared the serum BDNF level in male subjects aged 18-45 years. Four groups of 20 subjects each were included: individuals with tobacco use disorder only, patients having schizophrenia, patients with cannabis use disorder, and finally patients with comorbid cannabis use disorder and schizophrenia., Results: The BDNF levels were found to be significantly different across the four groups. The BDNF levels in subjects with concurrent schizophrenia and cannabis use disorder were higher than each of the other three groups (cannabis use disorder, schizophrenia, and tobacco use disorder only)., Conclusion: We find that BDNF may be higher when cannabis use disorder and schizophrenia co-occur, as compared to either of the conditions alone. The findings should be interpreted with caution due to the low sample size and potential confounders., (Copyright © 2024 Copyright: © 2024 Indian Journal of Pharmacology.)

Identifying biomarkers for diagnosing Major Depressive Disorder (MDD), assessing its severity, and guiding treatment is crucial. We conducted whole genome transcriptomic study in North Indian population, and analyzed biochemical parameters. Our longitudinal study investigated gene-expression profiles from 72 drug-free MDD patients and 50 healthy controls(HCs) at baseline and 24 patients after 12-weeks of treatment. Gene expression analyses identified differentially expressed genes(DEGs) associated with MDD susceptibility, symptom severity and treatment response, independently validated by qPCR. Hierarchical clustering revealed distinct expression patterns between MDD and HCs, also between mild and severe cases. Enrichment analyses of significant DEGs revealed inflammatory, apoptosis, and immune-related pathways in MDD susceptibility, severity, and treatment response. Simultaneously, we assessed thirty biochemical parameters in the same cohort, showed significant differences between MDD and HCs in 13 parameters with monocytes, eosinophils, creatinine, SGPT, and total protein remained independent predictors of MDD in a multivariate-regression model. Our study supports the role of altered immune/inflammatory signaling in MDD pathophysiology, offering clinically relevant biochemical parameters and insights into transcriptomic gene regulation in MDD pathogenesis and treatment response., Competing Interests: Declaration of Competing Interest The authors declare no competing interests., (Copyright © 2023.

Background: The clinical heterogeneity in major depressive disorder (MDD), variable treatment response, and conflicting findings limit the ability of genomics toward the discovery of evidence-based diagnosis and treatment regimen. This study attempts to curate all genetic association findings to evaluate potential variants for clinical translation., Methods: We systematically reviewed all candidates and genome-wide association studies for both MDD susceptibility and antidepressant response, independently, using MEDLINE, particularly to identify replicated findings. These variants were evaluated for functional consequences using different in silico tools and further estimated their diagnostic predictability by calculating positive predictive values., Results: A total of 217 significantly associated studies comprising 1200 variants across 545 genes and 128 studies including 921 variants across 412 genes were included with MDD susceptibility and antidepressant response, respectively. Although the majority of associations were confirmed by a single study, we identified 31 and 18 replicated variants (in at least 2 studies) for MDD and antidepressant response. Functional annotation of these 31 variants predicted 20% coding variants as deleterious/damaging and 80.6% variants with regulatory effect. Similarly, the response-related 18 variants revealed 25% coding variant as damaging and 88.2% with substantial regulatory potential. Finally, we could calculate the diagnostic predictability of 19 and 5 variants whose positive predictive values ranges from 0.49 to 0.66 for MDD and 0.36 to 0.66 for response., Conclusions: The replicated variants presented in our data are promising for disease diagnosis and improved response outcomes. Although these quantitative assessment measures are solely directive of available observational evidence, robust homogenous validation studies are required to strengthen these variants for molecular diagnostic application., (© The Author(s) 2023.

Aims and Objectives: To assess the current patterns and experience of internet use among persons with depressive and anxiety disorders, particularly for health-related issues., Methodology: In-depth interviews were conducted with persons diagnosed with depressive and anxiety disorders (DSM-5), aged ≥18 years who could read and write in Hindi/English, using an interview guide. The interview guide contained questions related to internet use in daily life, internet use for health-related issues, and internet use for stress, and internet use for anxiety/depressive disorder. Interview data were transcribed and analyzed to identify codes and subsequently themes., Results: A total of 20 subjects; 10 each diagnosed with depressive and anxiety disorders were interviewed. About half the participants could operate internet independently, while rest required assistance. YouTube was the most common search engine used, and leisure was the most common reason for daily use. Almost all participants reported searching internet for health-related information including their psychiatric diagnosis. The most common purpose, for health in-general, was searching for alternate therapies. Most common purpose for psychiatric diagnosis was understanding the symptoms, recovery from their illness, and side effects of medicines. Highest impact as perceived by the participants was on distraction or stress reduction rather than direct impact on the illness/treatment., Conclusion: Persons with depressive and anxiety disorders use internet for distraction, communication, and seeking information about the illness and medicines., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Industrial Psychiatry Journal.)

Background and Aims: There is lack of research on somatic symptoms in schizophrenia. We aimed at finding prevalence and types of somatic symptoms in patients with schizophrenia and assessed their association with socio-demographic and clinical characteristics., Methods: We assessed somatic symptoms using Patient Health Questionnaire-15 (PHQ-15) in 93 patients with schizophrenia diagnosed on ICD10-DCR. Scale for Assessment of Positive Symptoms and Scale for Assessment of Negative Symptoms, WHO Disability Assessment Schedule 2.0, WHO Quality of Life (BREF) Hindi version and Liverpool University Neuroleptic Side-Effect Rating Scale were used to assess psychopathology, disability, quality of life and side effects., Results: Significant somatic symptoms (n ≥5 on PHQ-15) were present in 62 (67.7%) patients with schizophrenia. Forty three (69.4%) had mild ( n = 5-9 on PHQ-15), 17 (27.4%) had moderate ( n = 10-14 on PHQ-15), and only 2 (3.2%) had severe ( n = ≥15 on PHQ -15) somatic symptoms. Mean somatic symptoms score on PHQ-15 was 7.28 (± 3.83); 96.8% reported feeling tired, 76.3% had constipation or diarrhoea, 67.7% trouble in sleeping, 61.3% nausea or indigestion, 52.7% back pain and 51.6% headache. Patients with somatic symptoms were older in age, had longer duration of illness and treatment, and had more negative symptoms. They had higher disability and poor quality of life especially in physical domain., Conclusion: Somatic symptoms are common in patients with schizophrenia and are associated with chronicity, refractoriness and negative symptoms, significant disability and poor quality of life. Thus during routine clinical practice, somatic symptoms should be assessed and managed in these patients., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Indian Journal of Psychiatry.)

Objectives: To assess disability and quality of life (QOL) in treatment resistant schizophrenia (TRS) on long term clozapine therapy and assess their correlation with positive, negative and cognitive symptoms., Methodology: Disability and QOL in forty patients with TRS (as per modified Kane's criteria) were assessed using World Health Organization Disability Assessment Schedule 2.0 and World Health Organization Quality of Life-BREF. Scale for assessment of positive symptoms, scale for assessment of negative symptoms and Addenbrooke's cognitive examination-III were used to assess positive, negative and cognitive symptoms. Medication adherence rating scale assessed medication adherence., Results: Disability and QOL correlated significantly with medication adherence, negative and cognitive symptoms but not with positive symptoms. Subgroup analysis revealed significant difference between medication adherence (good vs poor) and cognitive (impairment vs non-impairment) groups., Conclusion: Negative and cognitive symptoms, and medication adherence correlated with disability and QOL., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Indian Journal of Psychiatry.)

Objective: Developing countries such as India face a major mental health care gap. Delayed or inadequate care can have a profound impact on treatment outcomes. We compared pathways to care in first episode psychosis (FEP) between North and South India to inform solutions to bridge the treatment gap., Methods: Cross-sectional observation study of 'untreated' FEP patients (n = 177) visiting a psychiatry department in two sites in India (AIIMS, New Delhi and SCARF, Chennai). We compared duration of untreated psychosis (DUP), first service encounters, illness attributions and socio-demographic factors between patients from North and South India. Correlates of DUP were explored using logistic regression analysis (DUP ≥ 6 months) and generalised linear models (DUP in weeks)., Results: Patients in North India had experienced longer DUP than patients in South India (β = 17.68, p < 0.05). The most common first encounter in North India was with a faith healer (45.7%), however, this contact was not significantly associated with longer DUP. Visiting a faith healer was the second most common first contact in South India (23.6%) and was significantly associated with longer DUP (Odds Ratio: 6.84; 95% Confidence Interval: 1.77, 26.49). Being in paid employment was significantly associated with shorter DUP across both sites., Conclusions: Implementing early intervention strategies in a diverse country like India requires careful attention to local population demographics; one size may not fit all. A collaborative relationship between faith healers and mental health professionals could help with educational initiatives and to provide more accessible care., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Objectives: We assessed and correlated neurochemical levels and cognitive functions in left dorsolateral prefrontal cortex (DLPFC) and left hippocampus in euthymic patients with bipolar disorder and compared these with healthy controls METHODOLOGY: Twenty-five right-handed euthymic patients (HAM-D score < 7, and YMRS score < 7) with bipolar disorder and 20 age and gender matched controls were compared for neurometabolites (n-acetylaspartate - tNAA, choline - Cho, creatinine - Cr, myoinositol - Ins, and glutamine/glutamate - Glu/Gln) measured in left DLPFC and left hippocampus using single voxel magnetic resonance spectroscopy (MRS) and cognitive functions assessed using trail making test (TMT - A and B), wisconsin card sorting test (WCST), and wechsler memory scale (WMS-III Indian adaptation)., Results: The two groups were comparable on socio-demographic variables. tNAA levels in DLPFC and hippocampus, and glutamate levels in hippocampus were found to be significantly lower and Inositol and glutamine levels in hippocampus were found to be significantly higher in patients as compared to controls. Patients performed significantly poorly as compared to controls on TMT A & B, all subscales of WMS - III, 5 subscales of WCST, including perseverative responses and errors. The tNAA and glutamate levels in left DLPFC in patients correlated with scores on TMT A & B, and several subscales of WCST and WMS-III. tNAA concentration in left hippocampus in patients correlated with scores on subscales of WMS-III., Conclusion: Neurochemical dysfunction in select brain areas directly correlates with impairment in cognitive functions seen in patients with bipolar disorder in euthymic phase., Competing Interests: Conflict of Interest Nil., (Copyright © 2022 Elsevier B.V.

Rationale: Alpha lipoic acid is known to reverse NMDA receptor hypofunction in addition to dopamine receptor blockade activity. It also enhances neurotrophic factors and has antioxidant potential. These properties combined together may be beneficial for treatment-resistant schizophrenia (TRS)., Objectives: This study evaluates the effect of alpha lipoic acid (ALA) on psychopathological scores (positive, negative, cognitive), neurotrophic factors and oxidative stress in TRS., Methods: A pilot randomized double-blind placebo-controlled parallel design trial was conducted in 20 patients with TRS. After initial screening, participants were randomized into test (add-on ALA) and control (add-on placebo) groups. After recruitment, clinical evaluations with scale for assessment of positive symptoms and negative symptoms (SAPS and SANS), schizophrenia cognitive rating scale (SCoRS), UKU side effect rating scale were done. Serum levels of BDNF, MDA, and GSH were estimated. Patients were followed up for 8 weeks, and clinical and biochemical evaluations were repeated. Adherence to medication was evaluated at follow-up., Results: A significantly greater improvement was found in SANS score in the test group when compared to control (Mann-Whitney U = 17.0; p = 0.021), whereas there was no significant improvement in SAPS score (Mann-Whitney U = 41.5; p = 0.780). A significant increase in BDNF levels was observed in the control group when compared to ALA (U = 20.0; p = 0.041). No significant differences were found between the test and control groups in serum MDA (U = 30.0; p = 0.221), serum GSH (U = 40.0; p = 0.683), and medication adherence rating scale (MARS) scores (U = 44.0; p = 0.934)., Conclusions: ALA supplementation improved psychopathology and decreased oxidative stress in patients with TRS. This study thus shows the potential of adjunctive ALA in TRS., Trial Registration: The study was prospectively registered in Clinical Trial Registry of India (CTRI/2020/03/023707 dated 02.03.2020)., (© 2022.

This paper introduces the TRANSFORM project, which aims to improve access to mental health services for people with serious and enduring mental disorders (SMDs - psychotic disorders and severe mood disorders, often with co-occurring substance misuse) living in urban slums in Dhaka (Bangladesh) and Ibadan (Nigeria). People living in slum communities have high rates of SMDs, limited access to mental health services and conditions of chronic hardship. Help is commonly sought from faith-based and traditional healers, but people with SMDs require medical treatment, support and follow-up. This multicentre, international mental health mixed-methods research project will (a) conduct community-based ethnographic assessment using participatory methods to explore community understandings of SMDs and help-seeking; (b) explore the role of traditional and faith-based healing for SMDs, from the perspectives of people with SMDs, caregivers, community members, healers, community health workers (CHWs) and health professionals; (c) co-design, with CHWs and healers, training packages for screening, early detection and referral to mental health services; and (d) implement and evaluate the training packages for clinical and cost-effectiveness in improving access to treatment for those with SMDs. TRANSFORM will develop and test a sustainable intervention that can be integrated into existing clinical care and inform priorities for healthcare providers and policy makers.

Altered neural oscillations during prestimulus-task conditions have been reported to be associated with aberrant information processing in schizophrenia. Spectral perturbations induced by visuo-spatial working memory (VSWM) task were investigated in patients and their first-degree relatives in order to study the biomarkers in schizophrenia. EEG was recorded using 128-channel during VSWM task in 28 patients, 27 first-degree relatives and 25 controls. After pre-processing and ICA, current dipole was estimated for each IC. Total of 1609 independent and localizable EEG components across all groups were used to compute ERSP during different events of task. Patients deactivated DMN, RSN, auditory cortex more compared to controls during search period to perform VSWM task. Relatives showed altered activation of right medial and inferior frontal gyri during different events and loads of task in lower frequencies compared to controls. Relatives also showed hyperactivity in right cingulate and parahippocampal gyri compared to controls. This is suggestive of genetic predisposition in schizophrenia and could act as vulnerability markers, further strengthened by no significant differences between patients and relatives. Altered processing of simultaneous ongoing events in patients and relatives can serve as state and trait-specific features of schizophrenia., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2022.

Objective: Depression is an important co-morbidity in persons with epilepsy (PWE) and its timely identification is essential. The aim of the study was to assess and compare the psychometric properties of potentially suitable screening tools of depression in PWE in a tertiary care setting in India., Methods: After ethical clearance, 449 PWE above 18 years of age, on anti-seizure drugs (ASDs), attending epilepsy clinic in neurology outpatient department (OPD) of All India Institute of Medical Sciences, New Delhi, India, were recruited and evaluated for depression using different tools namely: Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), Patient Health Questionnaire (PHQ-9) and Hamilton Depression Rating Scale (HAM-D). Mini International Neuropsychiatric Interview (MINI: Module A, version 6.0.0) was used as reference standard. The association if any of depression with PWE variables was also determined., Results: A variable percentage of PWE were positive for depression- 40.1% with MINI, 40.5% with NDDI-E, 44.3% with HAM-D and 45.4% with PHQ-9. Suicidal ideation was present in 4.5% of PWE. The sensitivity and specificity of scales using MINI as a reference standard were found to be maximal at scores ≥5, ≥8 and >11 for PHQ-9, HAM-D, and NDDI-E, respectively. The ROC analysis revealed a statistically significant difference among NDDI-E and PHQ-9 (p = 0.0268). Polytherapy in PWE had significant association with risk of depression (p < 0.01) and female PWE had 1.5 times the odds of depression as compared with males (95% CI, 1.02-2.2)., Conclusion: All the tools used in this study were found to be appropriate for use in PWE if cut-off points are validated. The choice of tool can be based on the clinical setting., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Non-surgical factors have been found to have significant impact on outcome following Total Knee Arthroplasty (TKA). The study was conducted to know the independent effect of each of the four interacting psychological factors: anxiety, depression, pain catastrophizing and kinesiophobia on early outcome following TKA in an Indian population., Materials and Methods: 104 consecutive patients undergoing TKA were included in the study and followed up at 6 weeks, 6 months and one year. Preoperatively, Hospital Anxiety and Depression Scale was used to diagnose and quantify anxiety and depression, pain catastrophizing and kinesiophobia were assessed using Pain Catastrophizing Scale and Tampa Scale for Kinesiophobia, respectively. Outcome was assessed on the basis of Knee Society Score and Knee Injury and Osteoarthritis Outcome Score. Regression analysis was done to know independent effect of each factor on outcome scores., Results: Nine (8.7%) patients were found to have undiagnosed psychopathology. The patients with psychopathologies were found to have significantly worse knee outcome scores on follow-up, although the rate of improvement in knee symptoms and function was not significantly different from those without psychopathology. The degree of Anxiety correlated with worse knee pain and stiffness up to 6 months while it correlated with poor knee function for a longer duration. The degree of depression and pain catastrophizing correlated with worse knee pain, stiffness and function at all visits while kinesiophobia didn't show correlation independent other factors., Conclusion: Psychopathology was found to be associated poor knee outcome scores with degree of preoperative depression and pain catastrophizing as significant independent predictors as poor outcome, whereas the effect of degree of anxiety on knee pain and stiffness was found to wane over time. Kinesiophobia didn't show any independent correlation., Supplementary Information: The online version of this article (10.1007/s43465-020-00325-x) contains supplementary material, which is available to authorized users., Competing Interests: Conflict of interestEach author certifies that he or she has no commercial associations (e.g. consultancies, stock ownership, equity interest, patent/licensing arrangements, etc.) that might pose a conflict of interest in connection with the submitted article.

Background: Abnormalities in brain development and plasticity have been associated with the pathophysiology of schizophrenia. The role of brain-derived neurotrophic factor (BDNF) in schizophrenia is the recent area of interest because it regulates neurogenesis. The current study aimed to assess and compare serum BDNF levels between first-episode schizophrenia patients and healthy controls, and evaluate its correlation with the socio-demographic and clinical variables., Methodology: It was a cross-sectional comparative study for the assessment of serum BDNF levels between patients with first-episode schizophrenia (N=50) and healthy controls (N-50) conducted in the Department of Psychiatry at a tertiary care public hospital attached to a medical school in North India. Participants were assessed for the socio-demographic parameters, nicotine dependence, and clinical details using structured scales. Serum BDNF level estimated using the sandwich ELISA technique. The comparison between the groups was done by using a Student t-test or chi-square test. Spearman correlation was performed between mean BDNF scores and demographic or illness variables in both first-episode schizophrenia and healthy control groups., Results: There was a significantly lower mean score of total serum BDNF levels in first-episode schizophrenia patients as compared to controls (8.44 ± 1.54 vs 10.44 ± 2.04; t = 5.52, p < 0.001; 95% CI = 1.28-2.71). The total FTND scores for smokeless tobacco use were negatively correlated to BDNF levels among healthy controls (r=-0.30, p=0.03) as well as in the first-episode schizophrenia group (r=-0.32, p= 0.04). None of the other illness-related variables were correlated to serum BDNF values in the first episode schizophrenia group., Conclusion: Individuals with first-episode schizophrenia have lower serum BDNF levels than healthy controls. The illness-related factors such as duration of untreated psychosis or psychopathology were not correlated with BDNF levels. Thus abnormal signaling of BDNF can lead to abnormal brain functioning which can make an individual more susceptible to schizophrenia., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Synchronized and coherent activity in resting-networks during normal brain functioning could be altered in disconnection syndrome like schizophrenia. Study of neural oscillations as assessed by EEG appears to be a promising proposition to understand the pathophysiology of schizophrenia in patients and their first-degree relatives, where disturbances in neural oscillations point towards genetic predisposition. Therefore, present study aims at establishing EEG based biomarkers for early detection and management strategies. Thirty-two patients with schizophrenia, 28 first-degree relatives and 31 healthy controls (HC) participated in the study. Resting brain activity was recorded using 128-channel electroencephalography. After pre-processing and independent component analysis (ICA), an equivalent current dipole was estimated for each IC. Total of 1551 independent and localizable EEG components across all groups were used in subsequent analysis. Power spectral density and source coherence between IC clusters were computed. Patients and first-degree relatives displayed significantly higher power spectral density (PSD) than HC for all frequency bands in left parahippocampal gyrus (PHG) (-7, -26, 8; BA 27). Another region within left deep PHG (-4, -28, 1), however, distinguished patients from first-degree relatives and HC in terms of significantly lower PSD in higher frequency bands. Functional connectivity (FC) was found to be lower in patients and higher in relatives compared to HC between different resting-state network areas. In patients, connectivity was lower compared to first-degree relatives. Altered activity within left PHG and FC of primarily this with other areas in resting-state network can serve as state and trait markers of schizophrenia., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2020 Elsevier B.V.

Introduction: Major Depressive Disorder (MDD) is a broad heterogeneous diagnostic construct. Previous studies have shown that it can be resolved into several symptom-clusters which are proposed to be associated with single nucleotide polymorphisms (SNPs) of the serotonergic pathway (5-HTTLPR, 5HTR1A, 5-HTR2A)., Methods and Material: In a cross-sectional study conducted at a tertiary level mental health care set-up in north India, 80 out-patients with MDD were evaluated with Montgomery Asberg Depression Rating Scale (MADRS) and then genotyping was done. The different clinical and genetic variables were compared across the factor structures of MADRS. Also, the comparison of the genetic data of cases was done with the pre-existing database of the non-blood related healthy ethnically-matched controls., Results: There was no significant association between age, gender, other clinical variables, SNPs like 5-HTTLPR SS/SL, rs6295 CC/CG/GG, rs6311GG/GA/AA, rs6313 CC/CT/TT and different factor-structures like 'detachment' consisting of items like concentration difficulty, lassitude, inability to feel; 'psychic anxiety' consisting of suicidal thoughts and inner tension; 'mood-pessimism' consisting of symptoms like apparent sadness, reported sadness, pessimistic thoughts and 'vegetative symptoms' like decreased sleep, poor appetite. Neither there was any association between genotype of the cases compared with the controls., Conclusions: No significant association was obtained between the four-factor structures of depression in MADRS and serotonin transporter and receptor SNPs in a study with a small sample size. This study evaluates whether depression symptom-clusters have distinct genotypic determinants and necessitates more comprehensive studies for unravelling the genetic determinants of depression., (Copyright © 2019.

Introduction: There have been a number of studies reporting on psychopathology of schizophrenia from South Asia, with the last study being reported about twenty five years back. The present study reports the clinical profile and frequency of symptoms in patients with schizophrenia and discusses the changing trends in psychopathology., Material and Method: Three hundred and thirty two patients with schizophrenia, aged 16-55, diagnosed as per DSM-IV-TR, were assessed for psychopathology on operational criteria OPCRIT checklist. The findings were compared with the previous studies on psychopathology of schizophrenia reported from South Asia., Results: Delusions (82.8%) followed by hallucinations (69.9%) were the most frequent psychopathology. First rank symptoms (FRS) were present in about three fourth of the subjects. Third person auditory hallucinations (68.6%) were the most common and thought echo (2.9%) was the least common FRS. One FRS was present in 31.7%, two in 24.7%, three in 17.7% and four in 6.8% of the subjects having FRS. A comparison with studies A comparison revealed that the prevalence of FRS were inbetween those reported in studies from Pakistan and India but higher than in the samples evaluated in Sri Lanka., Conclusion: Delusions and hallucinations with persecutory themes and FRS continue to be a common symptom in patients with schizophrenia., (Copyright © 2019 Elsevier B.V.

Background: Dhat syndrome is regarded by many as a culture bound syndrome of the Indian sub-continent. However the nosological status, conceptual understanding of the condition as well as the diagnostic guidelines are all mired in controversy., Aims: The current study aims to study the psychopathology of Dhat syndrome in men by using a qualitative approach and to arrive at an operational definition for diagnosing Dhat syndrome., Method: The qualitative approach consisted of five Focus Group Discussions (FGD) and five Key Individual Interviews (KII) with participants, consisting of patients as well as doctors - both allopathic as well as traditional., Results: Detailed analysis revealed valuable data regarding the symptoms, causes, treatment measures, socio-cultural context, psychiatric co-morbidity, nature of the disorder and various other phenomenological dimensions. Ideas for future nosological positioning were also specifically looked for. Operational definition and diagnostic guidelines were also arrived at based on the analysis as well as on previous literature., Conclusion: Although lot of agreement existed among various stakeholders about symptoms and presentation, they varied significantly in their opinion on nature of the condition and treatment. Suggestions for ICD 11 have been made., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Background: Major Depressive Disorder (MDD) is a broad heterogeneous construct resolving into several symptom-clusters by factor analysis. The aim was to find the factor structures of MDD as per Montgomery and Asberg Depression Rating Scale (MADRS) and whether they predict escitalopram response., Methods: In a longitudinal study at a tertiary institute in north India, 116 adult out-patients with non-psychotic unipolar MDD were assessed with MADRS before and after treatment with escitalopram (10-20mg) over 6-8 weeks for drug response., Results: For total 116 patients pre-treatment four factor structures of MADRS extracted by principal component analysis with varimax rotation altogether explained a variance of 57%: first factor 'detachment' (concentration difficulty, lassitude, inability to feel); second factor 'psychic anxiety' (suicidal thoughts and inner tension); third 'mood-pessimism' (apparent sadness, reported sadness, pessimistic thoughts) and fourth 'vegetative' (decreased sleep, appetite). Eighty patients (68.9%) who completed the study had mean age 35.37±10.9 yrs, majority were male (57.5%), with mean pre-treatment MADRS score 28.77±5.18 and majority (65%) having moderate severity (MADRS <30). Among them 56 (70%) responded to escitalopram. At the end of the treatment there were significant changes in all the 4 factor structures (p<0.01). Vegetative function was an important predictor of response (p<0.01, odd's ratio: 1.3 [1.1-1.6] 95% CI). Melancholia significantly predicted non-response (p=0.04)., Conclusions: Non-psychotic unipolar major depression having moderate severity in north Indian patients as per MADRS resolved into four factor-structures all significantly improved with adequate escitalopram treatment. Understanding the factor structure is important as they can be important predictor of escitalopram response., (Copyright © 2017 Elsevier B.V. All rights reserved.)
