Schizophrenia is a major public health problem associated with cognitive deficits, such as short and long term memory, executive functioning, attention and speed of processing that are amongst the strongest predictors of impaired functional outcome. In addition, schizophrenia patients show reduced "plasticity", defined as reduced learning. D-serine is a naturally occurring activator of the N-methyl-d-aspartate-type glutamate receptors (NMDAR) in the brain, and this project will assess the D-serine treatment over 16 weeks of a program designed to measure auditory plasticity.
An accurate identification of individuals at ultra-high risk (UHR) based on psychometric tools to prospectively identify psychosis as early as possible is required for indicated preventive intervention. The diagnostic comparability of several psychometric tools is unknown. To address the psychometric comparability of the CAARMS, SIPS and BSABS for subjects who are the immediate family and three-generation blood kinship of patients with schizophrenia. To verify the viability and reliability of the three instruments for these subjects. subjects who all are immediate family and three-generation blood kinship of patients with schizophreniawere interviewed. All the subjects were assessed for a UHR state by three psychometric tools including CAARMS, SIPS and BSABS. The psychometric diagnosis results including at risk of psychosis (UHR+), not at risk of psychosis (UHR-), and Psychosis. Demographic and clinical characteristics interviewed by these three instruments were also measured. The inter-rater agreement was assessed for evaluation of the coherence of the three scales. Transition rates of CAARMS, SIPS and BSABS for UCH+ subjects within 2 years were also recorded.There is good diagnostic agreement between the CAARMS, SIPS and BSABS towards identification of UHR subjects who are immediate family and three-generation blood kinship of patients with schizophrenia. Also, these three instruments are reliable and valid for assessing and detecting at risk mental states in these subjects.
This study is dedicated to exploring the brain mechanism of medication-resistant auditory hallucinations and developing effective treatment methods for them by using both cross-sectional and longitudinal designs. The continuous theta burst stimulation(cTBS) treatment mode, with the left cerebellum Crus II as the stimulation target, is applied to treat the schizophrenia patients with the medication-resistant auditory hallucinations. At the same time, the first-episode schizophrenia patients with auditory hallucinations were recruited as a test cohort to examine that brain mechanism of general auditory hallucinations in schizophrenia may be the structural and functional abnormalities in the temporoparietal circuit.
In psychiatry, caregiver burden is associated with excess physical and psychological morbidity in relatives of patients with schizophrenic disorders Single or multi-family psychoeducation for caregivers of patients with schizophrenic disorders or first episode psychosis has a direct benefit on the health of the caregiver and an indirect benefit on the health of the ill family member. It is associated with a reduction in the rate of relapse and re-hospitalization and with better compliance with treatment. For single-family psychoeducation, the number of caregivers to be treated to avoid re-hospitalization of the sick family member is 3. For caregivers, psychoeducation is accompanied by an improvement in knowledge of the disorders and coping strategies. Therefore, international recommendations recommend that psychoeducation for caregivers be systematic, early, and integrated into routine care. Currently, the organization of the French care system does not allow these recommendations to be met. In order to increase the use of psychoeducation in France, early interventions for caregivers must be offered systematically. The effectiveness of early psychoeducation for caregivers needs to be evaluated; only three randomized controlled trials are available in the literature and none have been conducted in France.
Individuals with schizophrenia display a wide range of neurocognitive difficulties resulting in functional impairment and disability. Extensive evidence indicates insomnia and sleep disturbances play a substantial role in degrading cognitive functioning. However, the putative impact of insomnia and sleep disturbances on neurocognition and daily functioning has not been investigated in people with schizophrenia. The goal of this study is to characterize sleep in individuals with schizophrenia and quantify its impact on neurocognition and daily functioning.
The study team will conduct a Multisite Randomized Controlled Trial to evaluate the advantages and disadvantages of two approaches for quitting smoking among people with serious mental illness (SMI). The study will compare a novel app tailored to people with SMI, Quit on the Go, to a standard of care smoking cessation intervention. We will test the effectiveness of the Quit on the Go app, an intervention that has demonstrated feasibility and acceptability in the target population, as a tool for smoking cessation in people with SMI. Participants with SMI will be recruited across 2 sites (Duke University and Univ. at Buffalo).
This is a study of the efficacy and safety of BXCL501 in children and adolescents with acute agitation and either bipolar disorder or schizophrenia.
Serious mental illnesses require years of monitoring and adjustments in treatment. Stress, substance abuse or reduced medication adherence cause rapid worsening of symptoms, with consequences that include job loss, homelessness, suicide, incarceration, and hospitalization. Treatment visits can be infrequent. Illness exacerbations usually occur with no clinician awareness, leaving little opportunity to make treatment adjustments. Tools are needed that quickly detect illness worsening. At least two thirds of Veterans with serious mental illness use a smart phone. These phones generate data that characterize sociability, activity and sleep. Changes in these are warning signs for relapse. Members of this project developed an app that monitors and transmits these mobile data. This project studies passive mobile sensing that allows Veterans to self-track their activities, sociability and sleep; and studies whether this can be used to track symptoms. The project intends to produce a mobile platform that monitors the clinical status of patients, identifies risk for relapse, and allows early intervention.
This study will investigate whether the remote administration of the cognitive remediation program RC2S+ acceptable and feasible in people with schizophrenia and related disorders.
