Filter by:The benefits and harms of antipsychotics are relatively well studied in adults. However, there is a lack of scientifically valid studies regarding the benefits and harms of antipsychotics in children and adolescents with psychosis. The main objective of the TEA trial is to compare the efficacy and adverse reactions of two antipsychotics (quetiapine versus aripiprazole) in children and adolescents between 12-17 years of age with psychotic symptoms on psychopathology, cognitive deficits, and daily functioning. Furthermore, the trial will focus on adverse reaction profiles of the two antipsychotics as well as early predictors of later sustained clinical effects of these antipsychotics.
The purpose of this study is to learn if patients being treated with second generation antipsychotics and with clinically meaningful elevations/levels in any metabolic syndrome elements will have better access to medical treatment more quickly if they are randomized to one of the following conditions: 1) a primary care provider located in the community mental health center where mental health treatment is provided (IMBED), 2) a medical care manager to help coordinate treatment with an outside primary care provider (Liaison) or 3) the standard practice of advising the patient to see a primary care doctor (Treatment as Usual).
The purpose of this study is to evaluate the potential effect of multiple oral doses of an extended release formulation of paliperidone on the pharmacokinetics (blood levels) of valproic acid (VPA) in patients with schizophrenia, bipolar I disorder, or schizoaffective disorder.
The purpose of this study is to determine whether individuals with psychotic spectrum disorders ( Schizophrenia, Schizoaffective disorder,Schizophreniform Disorder, Bipolar Disorder (Type I),Bipolar Disorder (Type II),Major Depressive Disorder With Psychotic Features,Substance-Induced Psychoses,Psychosis Not-Otherwise-Specified (NOS)randomly assigned to a stepped behavioral intervention for the prevention of weight gain will experience less weight gain than individuals who receive usual care. There are several studies that have examined the effect of pharmacological and non-pharmacological behavioural approaches for weight loss in patients with psychosis, however studies examining strategies for prevention of obesity are lacking. This study is an important and novel approach to studying the problem of obesity in those with psychosis.
Oxytocin (OXT) is currently regarded as a crucial neuropeptide in the mediation of various human social behaviors, e.g. social affiliation, social recognition, and the modulation of anxiety, mood, and aggression. An impairment of social behavior, emotional regulation as well as increased stress reactions are characteristic of several psychiatric conditions, including schizophrenia, social anxiety and PTSD, in which there is also some evidence for OXT dysfunction. The startle reflex is a basic defensive reaction that can be modulated by emotional stimuli. The investigation of the startle reflex and of its modulation is a well-validated method to test stress reactions and emotional regulation. These processes are impaired in the same psychiatric diseases, in which OXT dysfunction was evidenced. Although previous animal studies showed that the dysfunction of brain OXT systems might be implicated in startle reflex and in its modulation, no study has been performed yet in human that investigated the influence of OXT administration on the startle response and on its affective modulation. A first aim of this study is to investigate the influence of OXT on stress reactivity and emotional modulation in healthy humans. A second aim is to develop a method for the investigation of anxiety disorders. Fifty male healthy participants will be tested using a randomized double-blind placebo-controlled cross-over design in two occasions; once with administration of 24 IU OXT, and once with placebo using nasal sprays while performing a computer-based experiment, in which emotional pictures and auditory startle probes are presented. We will measure the subject's subjective ratings of the pictures as well as the facial EMG activation, heart rate and electrodermal activation throughout the study. This project offers a unique opportunity to study the relationship between the OXT system and basic motivational and emotional behaviors. The investigation of these mechanisms is in turn greatly worthwhile, not only for understanding of the neurochemical and physiological processes involved in emotional regulation, but also for the comprehension of the neuroendocrine and neurophysiological mechanismsunderlying anxiety disorders. In the long term, it could open the possibilities of OXT as a psychobiological therapeutics of psychiatric disorders.
The purpose of this study is to evaluate the effects of risperidone compared with other atypical antipsychotic drugs on the physical maturity, growth and development of children, and the risk of prolactin-related adverse events (side effects) associated to these drugs.
In 2003 the VA Undersecretary's Action Agenda mandated that mental health services throughout the system be transformed to a recovery model. That mandate and many of the Workgroup recommendations have since been formalized in the Uniform Mental Health Services Package, which specifies a range of recovery-oriented services that must be available to veterans. A key aspect of these policy mandates is the need to assess recovery status of veterans and to monitor their progress over time as a way to evaluate the effectiveness of recovery services. However, there is no established instrument that is suitable for system-wide application. The purpose of this project is to develop a reliable, valid and practical measure of recovery, and use the measure in a study to better understand recovery in veterans with serious mental illness.
The purpose of this study is to compare 6 monthly counseling sessions to 6 monthly information sessions on Veterans' decisions to (a) participate in vocational rehabilitation services and (b) become employed.
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.
