Objective: Schizophrenia is a severe mental disorder for which final outcomes continue to be unfavorable. The main objectives of this research were to examine and determine the baseline predictors of outcome status of first-episode schizophrenia in a long-term follow-up of ten years and of recovery ten years later.

Materials and Methods: The study was carried out in a non-governmental, psychiatric hospital and participants consisted of patients available for assessment ten years following their initial diagnosis. Outcome was assessed on clinical and social parameters. Clinical measures of outcome included psychopathology, hospitalization, and suicidality. Social parameters included quality of life functioning, employability, …


Should ‘Risk Syndrome Of Psychosis’ Be Included In Dsm V As A Diagnosis? A Road Towards Preventive Psychiatry”, Amresh Srivastava May 2010

Should ‘Risk Syndrome Of Psychosis’ Be Included In Dsm V As A Diagnosis? A Road Towards Preventive Psychiatry”, Amresh Srivastava

Amresh Srivastava

Psychiatric diagnosis has acquired a position of a quasi-legal document for mental health services and agencies working with mental health. Its utility has gone far beyond ‘clinical diagnosis for treatment’.

The concept of risk syndrome for schizophrenia has been thoroughly researched in last ten years or so. Significant advancement has been made in phenomenology, diagnostic criteria, classification, & neurobiology. The research of prodromal or at-risk or Ultra high-risk psychosis has significantly contributed to the body of knowledge of aetio-pathogenesis of schizophrenia.

The science of risk syndrome has apparently matured and its proponents are ready for its inclusion in DSM V …


Outcome, Early Intervention & Dup: The Matrix Of Research In Early Psychosis, Amresh Srivastava, Megan Johnston May 2010

Outcome, Early Intervention & Dup: The Matrix Of Research In Early Psychosis, Amresh Srivastava, Megan Johnston

Amresh Srivastava

There has been little investigation of the relationship of DUP to other long-term outcomes such as negative symptoms and cognitive functioning neither have the possible confounds of DUP been widely investigated or controlled. It is important that there should be more thorough investigations of DUP, its correlates, and the extent to which it does mediate any advantages of earlier intervention. Shorter duration of untreated psychosis was associated with greater response to antipsychotic treatment, as measured by severity of global psychopathology, positive symptoms, negative symptoms, and functional outcomes. At the time of treatment initiation, duration of initially untreated psychosis was associated …

Optimizing Outcome Measures For Schizophrenia: From Research To Clinics, Amresh Srivastava, Nina Schoolar, Alexander Miller, Jitenra Trivedi

Amresh Srivastava

Outcome measures in schizophrenia have evolved considerably to bring in more objectivity, uniformity and attempt to reflect ‘real-life’ situation. It has significantly moved away from measurement of symptom remission to assessment of level of functioning and quality of life parameters. Schizophrenia is a complex neurobehavioral disorder afflicting approximately 1% population, with onset in early adolescence, across the world. It cause immense burden of patients, families and caregivers. The economic cost of schizophrenia is enormous. It is therefore important that assessment of schizophrenia be reflective of ground reality, scientific, evidence-based and comprehensive. Several researchers have proposed multidimensional outcome parameters. The heterogeneity …

Amresh Srivastava

Duration of untreated psychosis (DUP) has emerged as a reliable predictor of outcome but continues to remain under scientific scrutiny. The present study examines the effect of differential periods of DUP on long-term outcome of first episode schizophrenia at Mumbai, India. This research was a prospective, 10-year follow-up naturalistic study. Hospitalized patients of first episode schizophrenia were selected and followed up. Results showed that the mean DUP was higher for a group which showed clinical recovery on Clinical Global Impression Scale [14.0 months (SD=8.0) in recovered and 10.8 months (SD=5.7) in non-recovered group (P=0.091)]. DUP was not found to be …

Integrating Social & Clinical Parameters In Outcome Measures Of Schizophrenia: Clinician’S Perspective., Amresh Srivastava, Nilesh Shah, Yves Bureau

Amresh Srivastava

Schizophrenia is a complex neurobehavioral disorder for which there are many promising new treatments. There is, however, a discrepancy in outcome measure reports when they are obtained from patients, relatives, caregivers, or professionals, thus making it difficult to determine the level of recovery. The reason for this lack of agreement may be due to the limitations of the measurement tools themselves, which are not comprehensive and may be measuring different aspects of outcome. Alternatively, it could be that the conceptual understanding of outcome and recovery require development. Unfortunately for one of the above reasons or both, patients assessed as “recovered” …

Social Cognition And Interaction Training (Scit) For Individuals With Schizophrenia Spectrum Disorders In Outpatient Treatment Settings, Petra Kleinlein Jan 2010

Social Cognition And Interaction Training (Scit) For Individuals With Schizophrenia Spectrum Disorders In Outpatient Treatment Settings, Petra Kleinlein

Department of Psychology: Dissertations, Theses, and Student Research

The role of social cognition in severe mental illness (SMI) has gained much attention, especially over the last decade. The impact of deficits in socio-cognitive functioning has been found to have detrimental effects on key areas of day-to-day functioning in individuals with SMI, such as gaining and maintaining employment and overall experienced quality of life. Treatment of individuals with SMI is challenging, as the presentation of individual signs and symptoms is rather heterogeneous. There are several treatment approaches addressing deficits ranging from broader social and interpersonal functioning to neurocognitive and more intrapersonal functioning. As research in the domain of social …

Persistent Suicide Risk In Clinically Improved Schizophrenia Patients: Challenge Of The Suicidal Dimension, Amresh Shrivastava, Megan Johnston, Nilesh Shah, Marco Innamorati, Larry Stitt, Meghana Thakar, David Lester, Maurizio Pompili

Amresh Srivastava

BACKGROUND: Suicide is a major problem in schizophrenia, estimated to affect 9%-13% of patients. About 25% of schizophrenic patients make at least one suicide attempt in their lifetime. Current outcome measures do not address this problem, even though it affects quality of life and patient safety. The aim of this study was to assess suicidality in long-term clinically improved schizophrenia patients who were treated in a nongovernmental psychiatric treatment centre in Mumbai, India.

METHOD: Participants were 61 patients out of 200 consecutive hospitalized first-episode patients with schizophrenia diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders who were …

Early Intervention In Psychotic Disorders: Challenges And Relevance In The Indian Context, Matcheri Keshavan, Amresh Shrivastava, Bangalore Gangadhar

Amresh Srivastava

Over the last two decades, there has been an increasing interest in the concept of early intervention (EI) in psychotic disorders, notably schizophrenia. Several lines of research underlie this emerging paradigm shift: (a) an increasingly well-established association between the duration of prolonged untreated illness and poor outcome; (b) evidence of progressive neurobiological changes in the early course of schizophrenia both in the pre-psychotic and psychotic phases, as evidenced by brain imaging studies in schizophrenia; and (c) emerging data, albeit preliminary, suggesting the efficacy and effectiveness of EI programs in improving the outcome in these patients. Mental health service systems across …

Lessons Learned From Research In Prodromal Phase Of Schizophrenia, Amresh Shrivastava, Megan Johnston

Amresh Srivastava

In the last ten years, a significant amount of research data has accumulated to identify and predict the vulnerability of individuals to develop psychosis. At a time when DSM-V academia is becoming active with field trials, researchers in prodromal psychosis research are arguing for inclusion of 'risk syndrome for psychosis,' which has generated an interesting debate. Studies indicate that approximately 80-85% of cases experience subsyndromal symptoms for a period lasting from several months to several years prior to the onset of the illness, including impaired perception, thought processes, subjective cognitive functions and mood. Also, much of the functional decline associated …
