Schizophrenia (SZ) is a highly debilitating neuropsychiatric disorder of young adulthood onset and a leading cause of disability worldwide. While treatments delivered at early stages of the disorder may be effective at reducing psychosis or altering the course of the disease, there are currently no biomarkers capable of identifying subjects in early stages of SZ who are likely to respond to treatment and would be good candidates for available proactive, symptomatic or future disease-modifying treatments; or those who would not respond and can be spared unnecessary medication exposure. The lack of these vitally important biomarkers provides a compelling rationale for the present multidisciplinary research project, which aims to develop and validate highly promising noninvasive and objective proton magnetic resonance spectroscopy (1H MRS)-based biomarkers for monitoring treatment response in early stages of SZ. In support of the viability of this overall objective is a large body of data, reported by the applicants and others, that show (a) that levels of glutamate (Glu) and - aminobutyric acid (GABA) - respectively, the major excitatory and inhibitory amino acid neurotransmitter systems - are abnormally elevated in medication-naïve and unmedicated first episode and chronic SZ patients; (b) that the effect of treatment with antipsychotic medications in these populations may be to lower or normalize brain levels of both Glu and GABA. To investigate the potential of these in vivo brain Glu and GABA abnormalities to serve as biomarkers of treatment response in early-stage SZ, the applicants propose to use 1H MRS to measure Glu and GABA levels in the largest cohort of medication-free SZ subjects to date, at baseline and following 4 weeks of antipsychotic treatment.
Participants will be administered several doses of pomaglumetad (POMA) (low and high doses) over 14 days to individuals at clinical high risk for developing psychosis and use magnetic resonance imaging (MRI) brain imaging to determine whether these doses of POMA are affecting glutamate levels.
The purpose of the study is to determine whether motivation/reward deficits observed in schizophrenia are attenuated and whether cognitive impairment associated with schizophrenia is improved by add-on TAK-041 administration to antipsychotics in participants with stable schizophrenia.
This study is a validation study to evaluate the acceptability, feasibility and impact of a mobile psychosocial intervention to enhance social functioning in people with schizophrenia.
This randomised three-arm study aims to evaluate the efficacy and feasibility of a cognitive behavioral therapy (INT-Integrated Neurocognitive Therapy for Schizophrenia Patients) in the treatment of schizophrenia patients in an inpatient setting. The intervention will be compared with an active comparator (IPT- Integrated Psychological Therapy) and a control condition. Overall the study will include 90 patients (30 in each arm). Each patient will receive at least 16 sessions of the respective treatment. Baseline and follow up assessments up to 12 months after the intervention will investigate the stability of treatment.
The current investigation aims to compare two group intervention in patients with a first episode of psychosis, that is, people who have suffered their first psychotic episode within 5 years prior to their inclusion in the study. The experimental arm is a mindfulness-based social cognition training (SocialMind) designed by professionals with both formal training and clinical experience in the field of mindfulness and third generation cognitive-behavioral therapies. The active comparator arm is a psychoeducation program specifically designed for individuals with recent onset psychosis by members of the team with great experience in delivering such interventions. The main outcome is social functioning, as measured by the Personal and Social Performance Scale (PSP), an instrument developed for psychotic patients. The main hypothesis is that the improvement in social functioning will be larger among the participants on the experimental arm, because there is enough evidence suggesting that deficits in social cognition are present even in the first stages of psychotic syndrome and related to social functioning and general disability. Moreover, mindfulness-based interventions have proven themselves effective in other severe mental disorders.
Schizophrenia (SCZ) is a chronic, severe and disabling mental disorder with unclear etiology and pathophysiology concerned with neuro-developmental,neurodegenerative abnormalities and cognitive impairmentslinked to behavioural changes.According to neurotrophic hypothesis, the changes result due to the abnormal regulation of neurotrophic factor, especially the decreased serum brain derived neurotrophic factor (BDNF) validated by several meta-analyses. However, the regulation of nerve growth factor (NGF) in SCZ remains unclear because of the inconsistent findings from the previous clinical studies. Lurasidone is a novel antipsychotic drug approved for adult SCZ and for affective symptomatology & cognitive deficits. Principal advantages over some other second-generation antipsychotics are its highly favourable metabolic profile and once daily dosing regimen. Some of the studies indicate that risperidone, olanzapine, clozapine & aripiprazole might not alter BDNF levels, at least within 8 weeks of treatment.While other two studies with olanzapine suggest that BDNF might influence the response to monotherapy in SCZ patients.All these previous studies are non-conclusive & contradictory to each other which draw our attention for doing the research further to reach a conclusive result about the effect of olanzapine and lurasidone on neurotrophic biomarkers in SCZ.
This study attempts to observe the effectiveness and safety of aripiprazole in hospitalized patients with acute schizophrenia episode, and to compare the different drug regimens that may be involved in order to clarify the characteristics of the population for taking aripiprazole and provide reference for clinical rational drug use.
Purpose and objective Schizophrenia is a chronic debilitating illness with cognitive deficits that cause serious impairment in psychosocial recovery and with few treatments to remediate these deficits. One area that holds great promise for the development of novel, effective therapies is noninvasive brain stimulation. The investigators have used one form of brain stimulation, transcranial magnetic stimulation (TMS), for some time to modulate and enhance cognitive function in the brain, especially working memory (WM) function, which has a central role in most executive processing that occurs in the brain. Theta burst stimulation (TBS) is a paradigm of TMS which has been shown to effectively modulate WM. Moreover, TBS can modulate gamma neural oscillations in the brain and neural activity, both of which have been implicated in the physiology of WM and pathophysiology of the disease process in schizophrenia, making these measures highly valuable for assessing physiological effects of TBS on cognition, quality of life and cortical inhibition. The purpose of this study is to evaluate the effect of TBS on WM in patients with schizophrenia, to develop evidence for potential brain stimulation techniques to treat cognitive deficits in schizophrenia. Study activities and population group: Study subjects will be inpatient schizophrenic individuals with minimal positive symptoms and predominant cognitive deficits at Duke University Hospital. In an initial session they will be screened and taught a WM task. Following this, one TBS session will follow in which TBS will target dorsolateral prefrontal cortex. They will perform the WM task before, with and after the TBS, with an expected pre-post enhancement of WM performance. Implications - There is a great need for treatments for cognitive deficits in schizophrenia. The results of this study will serve to generate pilot data for a much larger grant to develop a TBS therapy for remediating such cognitive deficits.
