Filter by:The investigators will compare the test-retest reliabilities of two cognitive batteries in people with schizophrenia: Cognitive Drug Research Computerized Cognitive Assessment System ("CDR") and MATRICS Consensus Cognitive Battery ("MCCB"). The investigators hypothesize that there will be a statistically significant difference in the test-retest reliabilities between MCCB and CDR. In addition, the investigators hypothesize that each of the two batteries will better measure certain areas of cognition. The investigators also hypothesize that scores from both batteries will correlate with quality of life scores, and that there will be a significant difference between the correlations of MCCB and CDR. The investigators hypothesize there will be a significant difference in patients' self-reported tolerability and satisfaction of the MATRICS versus CDR assessments. Lastly, the investigators hypothesize that there will be a significant difference in the MATRICS versus CDR batteries with respect to an administrator-rated score of practicality. Approximately 32 subjects will enroll in the study. Following consent and eligibility screening (visit 1) and baseline clinical assessment and training in the use of the CDR battery (visit 2), subjects will be randomized into one of two groups for visits 3 and 4. One group will complete the CDR and then MCCB in visit 3, as well as the Tolerability Scale for each battery. The other group will complete the batteries in reverse order during visit 3. Each group will complete both batteries again in reverse order for visit 4. Randomization will be done in blocks of 2. After completion of every 4 subjects, study administrators will complete the Practicality Scale for each battery.
Many individuals with schizophrenia also suffer from marijuana addiction. Clozapine, an atypical antipsychotic medication, may prove useful at preventing drug relapse in schizophrenic individuals who are seeking treatment for marijuana addiction. The purpose of this study is to compare the effectiveness of clozapine, vs. treatment-as-usual with other oral antipsychotics at reducing marijuana use in schizophrenic individuals.
The purpose of this study is to document the long-term safety of 25, 37.5, or 50 mg long-acting injectable risperidone given via injection to the gluteal muscle every 2 weeks to subjects with schizophrenia or schizoaffective disorder.
The principal aim of the project is to conduct an off-label adjunctive clinical trial evaluating varenicline as a treatment for core neurobiological and clinical deficits in schizophrenia, in addition to evaluating for smoking cessation in schizophrenia patients.
An open-label, multi-center, 6-week, sequential cohort study designed to determine the safety and tolerability of two dose ranges of BL-1020 in hospitalized subjects with chronic schizophrenia or schizo-affective disorder
Veterans with schizophrenia and schizoaffective disorder experience very high levels of disability and poor community outcome. Further improvements in community outcome for patients with these disorders will not occur simply through better control of clinical symptoms. Instead, it will be necessary to find treatments that address the key determinants of poor functional outcome. Evidence strongly suggests that basic (non-social) cognitive and social cognitive deficits are among the key determinants of functional outcome for these illnesses. The primary goal of this 2-year pilot study is to implement and validate a new remediation program for social cognition that is appropriate for veterans with schizophrenia and schizoaffective disorder.
Our overall aim is to determine if the administration of guanfacine in combination with aripiprazole, olanzapine, quetiapine, and/or risperidone is significantly more effective than any of those medications alone in treating some of the cognitive impairment in schizophrenia.
The purpose of this study is to learn how to help veterans play a stronger role in shaping their mental health care. Specifically we want to see if we can help veterans improve their mental health treatment by helping them decide if they want to involve family in their mental health treatment, and if so, how. The study will compare a "family member provider" program to an "enhanced treatment as usual approach" in achieving these goals.
In the last decade cognitive behavioural therapy (CBT) approaches for patients with schizophrenia have been developed, which where especially designed to reduce severity of positive symptoms, readmission rates, treatment non-compliance and disability. Although CBT addresses the key problems of early onset psychoses (EOP)treatment and first evaluations of CBT in adults with schizophrenia are promising, no experience with CBT in adolescents with EOP are available. Therefore the present study is conducted to develop a modified CBT (mCBT) for adolescents with EOP, to explore its acceptance and feasibility and to provide data for a realistic estimation of achievable effect size. Patients are randomized to receive either mCBT+TAU or TAU over a 9 month period. mCBT is an individual outpatient treatment of 20 session and 5 psychoeducational sessions with parents. Follow-ups for two years every 6 months are planned.
This is a double blind randomized investigation of donepezil for patients suffering from schizophrenia, undergoing ECT. Patients will be randomized to receive either donezepil or plasebo, in order to gauge whether donezepil has a protective effect on memory disfunction, while patients are treated with ECT. Several parameters will be invistigated at baseline: general psychopathological measures, memory function scales, side effects scales. The same measurements will be taken throughout the trial and one month after ending the ECT.
