Filter by:The investigators propose to test whether curcumin nanoparticles will improve behavioral measures and biomarkers of cognition and neuroplasticity in patients with schizophrenia who are already receiving a stable dose of antipsychotic.
The AGES-CM consortium aims to study the interaction between the polymorphisms of the candidate genes related with neurodevelopment, neurotransmission, brain progressive changes, cognitive functioning and stressful life events (prospective- and retrospectively assessed) and the association of the interactions with structural and functional brain measures, neuropsychological performance, biochemical and oxidative status in both in patients and controls. The investigators study aimed to examine the effectiveness of a parallel, structured, and specific psychoeducational group intervention (PE) for adolescent patients and their families by comparing it with treatment as usual).
The proposed pilot study is a randomized controlled study to assess effectiveness of transcranial direct current stimulation (tDCS) to enhance cognitive remediation therapy in patients with psychotic disorders. tDCS. Patients will be randomized into two arms: active tDCS vs. sham tDCS. The active tDCS will be applied at a current of 1-2 mA (milliamperes) via two saline soaked electrode sponges (3 cm x 4.5 cm) applied to the side of the head. The investigators hypothesis is that the use of tDCS will enhance the improvement seen with cognitive remediation therapy.
The guiding questions for this study are: can a U.S. adaptation of a successful Scandinavian approach (TIPS) to early detection substantially reduce the duration of untreated psychosis (DUP) and improve outcomes beyond an established first-episode service (FES)? The primary aim of this study is: 1. To determine whether an early detection intervention can reduce DUP in the US, as compared to usual detection. Early detection (ED) will be implemented in one US community (New Haven, CT), and usual detection efforts will continue in another (Boston, MA). DUP will be measured at admission to the corresponding first-episode services (STEP & PREP) in each community, over one year before and throughout ED implementation. The investigators hypothesize that DUP will be reduced significantly in the early detection site compared to the usual detection site; 2. A secondary aim is to determine whether DUP reduction can augment the outcomes of established FES on outcomes in the U.S. The investigators will measure symptoms, functioning and engagement with treatment at entry and over 1 year at each site. The investigators hypothesize that shorter DUP at one FES (STEP) will predict reduced distress and illness severity at entry and better early outcomes at STEP compared to PREP.
The early stages of schizophrenia are associated with significant decreases in social and intellectual abilities, with more declines in chronic disease. Studies have identified relationships between duration of untreated psychosis (the duration between the onset of positive symptoms and treatment) and worse long term outcomes. However, the neurobiology of this phenomenon and its implications for response to antipsychotic medications remain poorly understood. Glutamatergic excess altering brain connectivity might provide an explanation for why those with longer duration of untreated psychosis have worse clinical outcomes. The investigators propose to use neuroimaging to study 67 first episode psychosis subjects before and after sixteen weeks of treatment with risperidone, a common antipsychotic. We will measure (1) glutamate and (2) structural and functional brain connectivity and test the hypotheses that glutamatergic abnormalities are present in first episode patients and that longer duration of untreated psychosis is associated with greater connectivity abnormalities that set the stage for poor response to treatment. 67 demographic-matched controls will also be recruited as a comparison group - healthy controls will not receive antipsychotic medication. The investigator's previous studies have made progress in the understanding of abnormalities in the glutamate system and brain connectivity in unmedicated patients with schizophrenia and modulation of these by antipsychotic medication. Two indices of glutamatergic dysfunction have been identified. While antipsychotic medications appear to modulate glutamate, the disturbance in the relationship between metabolites is not restored with treatment. In addition, the investigators found that both structural and functional connectivity abnormalities in unmedicated patients with schizophrenia predict patients' response to treatment. To the investigator's knowledge, no other group has performed a study that uses a combination of complementary neuroimaging techniques that will allow generating a broad characterization of glutamatergic function and brain connectivity in first episode psychosis and change with treatment. The results of the proposed studies could suggest a mechanism by which the duration of untreated psychosis is associated with poor treatment response which might lead to new interventions to target the illness.
Previous research has suggested central nervous system inflammatory activity to be critically involved in disease development and progression in schizophrenia, with a complex interplay of inflammatory mechanisms leading to the development of brain abnormalities and medical symptoms related to schizophrenia. However, the mutual interactions of different inflammatory pathways and their relation to disease course have not been sufficiently studied. This study therefore aims to explore the interaction of neuroinflammatory mechanisms in patients with schizophrenia and to assess whether the inflammatory activity in schizophrenia is state-dependent and occurs mainly during psychotic episodes.
A person-centered substance use treatment component, the Natural Recovery Program, was developed in a residential substance use treatment setting. The Natural Recovery Program is comprised of small group therapy combined with pursuit of hobbies. The study examined treatment retention, treatment completion and satisfaction of participants of Natural Recovery compared to those who participated in core residential treatment activities alone.
The purpose of this study is to determine whether cognitive training exercises can improve cognitive functioning in young patients with recent-onset schizophrenia, schizoaffective, schizophreniform, and psychosis NOS who are being treated in community mental health settings. We will investigate the effects of web-based cognitive training exercises delivered on a portable laptop computer. The findings will provide us with valuable information on whether cognitive training can improve the cognition and functioning of young individuals early in the course of schizophrenia.
This study aims to look at the effectiveness of a combination of cognitive remediation and social cognition training to improve cognition and functioning when compared to cognitive remediation alone. The target population will be those who are experiencing their first episode of psychosis.
Roughly one third of disability pensions issued in Norway are classified as mental and behavioral disorders. The proposed study aims to evaluate the effect of an innovative intervention for returning people with moderate to severe mental health disorders to work: Individual Placement and Support (IPS).
