NCT05052853
Previous studies found that some NMDA-enhancing agents were able to improve clinical symptoms of patients with schizophrenia. Whether treatment of an NMDA-enhancing agent can benefit the treatment of prodromal schizophrenia deserves study.
NCT03970005
The Ohio State University Early Psychosis Intervention Center is implementing a specialized clinical program to serve individuals who meet clinical high risk criteria for a psychosis. The purpose of this study is to evaluate the long-term outcomes among individuals participating in this clinical service.
NCT03447548
Young people who are at great risk for developing psychosis have cognitive deficits which are strongly related to functioning in the community. This study looks to target a specific cognitive skill called processing speed to see if improving the ability to process information in a timely manner will improve social function in adolescents and young adults at risk for developing schizophrenia. Half will receive neurofeedback cognitive training targeting processing speed while the other half will receive an active control.
NCT06190483
This study will investigate whether a single dose of diazepam (5mg) compared to placebo can modulate brain chemistry (GABA/glutamate levels) and function (blood flow, neural response and connectivity during tasks and at-rest) in 24 individuals at clinical high-risk for psychosis.
NCT03149107
Schizophrenia is a severe mental disorder associated with significant impairments in affective, cognitive and social functioning. Consequently, a special interest in the prevention of schizophrenia and psychotic disorders has emerged. Pharmacological as well as psychological interventions show promising preventive effects. The purpose of this multicentric study is the investigation of possible preventive effects of a treatment combination containing a psychotherapy form and medication (N-Acetylcytein - NAC) in individuals with an enhanced risk for developing schizophrenia. Both treatment forms may reduce the risk in this population due to their specific properties: The psychotherapy can improve social skills, whereas NAC is supposed to develop its protective effects on neuronal level due to its antiinflammatory properties. The investigators will examine the preventive effects by measuring transition rates to psychosis after treatment as well as improvements in social, affective and cognitive functioning.
NCT01597141
The primary aim of this application is to conduct a randomized, controlled clinical trial of a specialized mental health service delivery system specifically developed for prodromal psychotic disorders. The intervention is Family-aided Assertive Community Treatment (FACT). The goal of the treatment is prevention of psychosis and disability. This study will assess experimentally the clinical effectiveness of this new type of mental health service. Other domains of outcome include cognitive dysfunction and functional disability.
NCT01619319
Onset of psychotic disorders such as schizophrenia, typically occurs during late adolescence or early adulthood often resulting in chronic social and occupational disability. Deficits in cognition and functional outcome often precede the onset of full-blown psychosis although to a lesser degree than observed in schizophrenia. Recent progress in risk identification methodology has enabled reliable detection of persons who appear to be putatively prodromal for psychosis, that is, at clinical high risk (CHR) of developing a psychotic disorder. Since these CHR individuals already evidence cognitive deficits, which increase around the time of conversion, cognition is an excellent treatment target. Furthermore, there is clear evidence, in schizophrenia and in CHR samples, that deficits in cognition are related to poor functional outcome. Thus, treatments targeting cognition may consequently improve functional outcome. The primary aim of the project is to reduce cognitive deterioration and improve cognition among youths at CHR using cognitive remediation and to test the effectiveness of a new cognitive remediation program, the Brain Fitness program, in improving cognition of CHR individuals. A control treatment consisting of video games (VG) will be used. The primary hypothesis is that the BF group will have improved cognition at the end of treatment and 12 months post baseline compared to the VG group. A secondary hypothesis is that improved cognition will be associated with improved functioning. This is a longitudinal, single blind, placebo controlled pilot trial of cognitive remediation in 36 CHR persons. Participants will be randomised to either the BF or VG program, which will be administered over a period of 3 months. Assessments will occur at baseline, post treatment (3 months) and at 12 months after baseline. All subjects will be recruited in year 1 of the project and treatment will be completed by 15 months. The 40 hours of training will occur 4 days a week, for an hour each day, over a period of 10 -12 weeks.
