Filter by:This study seeks to examine the effectiveness of citalopram added to treatment with any oral or injectable second-generation antipsychotic plus standardized psychoeducation in first episode schizophrenia patients. Because depressive symptoms are common in first episode patients, we will test the hypothesis that adding the SSRI citalopram to a pre-established medication regimen will improve quality of life and decrease relapse and suicidality over the course of a 12-month trial.
Background: - Eye tracking, the ability to focus on and follow a moving target with the eyes, is often difficult for people who have schizophrenia. Research has shown that first-degree relatives of people with schizophrenia, such as parents and siblings, also tend to have difficulty with smooth eye movement and eye tracking. Researchers are interested in using functional magnetic resonance imaging (fMRI) to study brain activity during eye tracking tests in order to better understand the effect that schizophrenia has on brain function. Objectives: - To study eye-tracking and eye-tracking impairments in people with and without schizophrenia. Eligibility: - Individuals between 18 and 62 years of age in one of three groups: (1) patients who have been diagnosed with schizophrenia/schizoaffective disorder, (2) first-degree relatives of patients in group 1, and (3) healthy volunteers with no family history of psychosis. Design: - The study will involve two visits, one screening session and one testing session. Each session will take about 3 hours. - Participants will be asked to avoid consuming alcohol and restrict consumption of caffeine before the start of the study. Participants will provide urine and breath samples to be tested for chemicals that may interfere with the study. - Participants will visit the clinical center the morning of the day before the scanning session to provide blood and urine samples as required. Participants will return and be admitted for an overnight stay later that afternoon or evening. - During the screening session, participants will provide a medical and psychological history, provide blood samples, and learn the eye movement tasks they will do during the scanning session. - During the scanning session, participants will have an fMRI scan. During the scan, they will perform eye movement tasks that involve following moving light targets on a screen, and will also perform other tasks that test the ability to think and pay attention.
The study is designed to evaluate the effectiveness of computerized cognitive skills training for improving memory and problem-solving skills in inpatients with schizophrenia.
The main aim of the trial is to study whether a change of medication in non-responders to a two-weeks antipsychotic drug trial is more effective than continued treatment with the same antipsychotic. Hypothesis: Non-responders who are switched at 2 weeks to another antipsychotic are more frequently in symptomatic remission at week 8 than non-responders who stay on the same antipsychotic
This study is aimed to evaluate the bipolar disorder symptoms in patients presented with schizophrenia, schizoaffective disorder or recurrent depression. Bipolar disorder is a group of mood disorders characterised by elevated or irritable mood episodes in patient's lifetime history accompanied by some additional symptoms. In this study modern bipolar disorders screening/assessment instruments will be used to explore the prevalence of bipolarity symptoms in patients who never been diagnosed with bipolar disorders. The results of this study could be useful for more accurate assessment of bipolar disorders prevalence in psychiatric patient population, could help to improve the diagnostics of bipolar disorders and management of bipolar patients.
The purpose of this study is to examine whether an intensive computerized intervention targeted on improving central auditory and visual processing and executive functioning can be implemented in youths aged 10-19 with psychotic spectrum disorders, what developmental modifications are needed particularly for the younger participants, and whether it is possible to develop an appropriate, blinded control intervention.
The aim of the study is to investigate the efficacy and safety of aripiprazole in patients with first episode psychosis.
The objective of this study is to evaluate predictors of response to antipsychotic medication in subjects with schizophrenia. The investigators will evaluate psychopathology,brain MRI, genetics and neuropsychological profile. Two groups of treatment will be compared: first generation antipsychotics vs. second generation antipsychotics. Participants will be randomized to one of the groups. Trial duration: 12 weeks.
The study will determine if individuals with co-occurring bipolar disorder and alcohol dependence report reduced alcohol consumption, improvement in mood symptoms, and cognitive performance if treated with lamotrigine plus their usual mood stabilizing medications relative to subjects treated with placebo plus usual mood stabilizing medications over a 16 week period.
A large number of studies have investigated the psychological disorders occurred in postpartum women, and found that postpartum psychosis is common in new mothers. However, the situation of paternal psychological status after they had their first baby is not assessed. The investigators hypothesized that they had a high occurrence of paternal psychosis after first baby born. In addition, different factors might influence its onset and development in new fathers.
