NCT ID: NCT01844726 Terminated - Healthy Clinical Trials

Effects of GLYX-13 on Learning and Memory in Healthy Individuals and Those With Psychiatric Illness

Start date: May 2013
Phase: Phase 2
Study type: Interventional

The present study proposes to evaluate the potential cognitive enhancing effects of GLYX-13, an NMDAR partial agonist, among a group of healthy adults and those with psychiatric illness on a series of functional magnetic resonance imaging (fMRI) learning and memory tasks.

NCT ID: NCT01764568 Terminated - Schizophrenia Clinical Trials

Contrasting Group Therapy Methods for Psychosis

MCT
Start date: January 2013
Phase: N/A
Study type: Interventional

Current Canadian Clinical Practice guidelines emphasize the need for effective psychosocial adjuncts to pharmacotherapy for schizophrenia (Canadian Psychiatric Association 2005). This randomized control trial seeks to contribute to the body of evidence supporting psychosocial treatments by assessing the effectiveness of metacognitive training (MCT) and cognitive remediation (CR) at treating the persistent positive and cognitive symptoms of schizophrenia. MCT is a therapy designed to improve patient awareness and insight into the cognitive biases that are frequently seen in schizophrenia; it has been associated with decreased psychopathology (specifically decreased positive symptoms) and improved psychosocial function. CR is a therapy designed to improve performance in a variety of neurocognitive functions such as attention, memory, and executive functioning; it has been associated with improved cognitive and psychosocial functioning. Both MCT and CR will be compared to treatment as usual (TAU) as done previously (Kumar er al., 2010; Moritz et al., 2011). Hypotheses: 1. MCT will produce greater change in delusions (severity and conviction) than CR and TAU. 2. CR and MCT will produce greater change in social/everyday functioning than TAU. 3. CR will produce greater improvement in basic attention and memory measures relative to MCT and TAU. 4. MCT will produce greater reduction on tasks measuring targeted reasoning biases relative to CR and TAU. 5. CR will increase efficiency of functional networks on a working memory task relative to MCT and TAU. 6. MCT will lead to a greater decrease in the neural response to evidence matches relative to CR and TAU.

NCT ID: NCT01712646 Terminated - Schizophrenia Clinical Trials

Daily Intranasal Oxytocin for Childhood-Onset Schizophrenia

Start date: October 5, 2012
Phase: Phase 1/Phase 2
Study type: Interventional

Background: - Oxytocin is a chemical that the brain normally produces. It plays an important part in the way humans and other animals act in social and emotional situations. Adults with schizophrenia have been studied to see if oxytocin can reduce some symptoms of schizophrenia, such as hearing voices, feeling suspicious, and not feeling interested in daily life. These studies show that oxytocin may help. However, it has not been studied in children who develop schizophrenia. Researchers want to see if oxytocin, given as a nasal spray, is safe and can reduce schizophrenia symptoms in children. Objectives: - To see if an oxytocin nasal spray can reduce schizophrenia symptoms in children. Eligibility: - Children above 10 years of age who have childhood-onset schizophrenia, and have schizophrenia symptoms in spite of taking medication. Design: - This study will last 4 weeks. Participants will stay in the hospital for the entire period of the study. Participants may also have an extra 2 weeks of study medication and 1 week of testing immediately following the initial 4 weeks. - Participants will be screened with a physical exam and medical and psychiatric history. They will provide blood and urine samples, and have imaging studies of the brain. They will also have tests to look at their social and emotional functioning. These tests will take 1 week to perform. - Participants will have either oxytocin or placebo nasal spray twice daily for 2 weeks. - At the end of the 2-week period with nasal spray, there will be 1 week with no nasal spray. All the tests of week 1 will be repeated. - The optional extra 3 weeks (2 weeks with oxytocin and one week for testing) will be similar to the second, third, and fourth weeks of the study. All participants will have oxytocin during this period.

NCT ID: NCT01709526 Terminated - Clinical trials for Psychiatric Diseases

How the Adolescent Inpatients Are Rehabilitated After Discharge

AdolInpRehabi
Start date: January 2009
Phase: Phase 2/Phase 3
Study type: Interventional

The aims of this six month follow-up study are which treatment components will correlate or which clinical treatments interventions contribute adolescent inpatients recovering in the psychiatric treatment after discharge. Comparisons will be made between the 47 adolescents aged 13 to 18 years, with major depression and conduct disorders, and between those with and without suicide attempts by multivariate analyses. Are the adolescent psychiatric inpatients recovered?

NCT ID: NCT01662297 Terminated - Insomnia Clinical Trials

Comparison of Quetiapine and Trazodone Treatment for Insomnia in Dually Diagnosed Veterans

Start date: July 2012
Phase: Phase 4
Study type: Interventional

This is a pilot comparative effectiveness study designed to determine whether trazodone is as effective as quetiapine for treatment of insomnia in veterans with a history of addiction and mental health issues. The study will have two concurrent phases (parts); first an acceptability determination phase, to determine whether and why (or why not) veterans already taking quetiapine are willing to try an alternative to quetiapine for sleep; and second, a randomized trial phase which will test whether staying on quetiapine has any advantage over switching to trazodone. The purpose of the first phase will be a) to document the proportions of patients and physicians who are willing to agree to such a switch, b) to characterize sociodemographic and clinical characteristics of potentially eligible subjects associated with a willingness to switch from quetiapine to trazodone and c) to record the reasons given why patients and their prescribers are (or are not) willing to accept a switch from quetiapine to trazodone. It will also function to provide some educational background to patients and a reminder to providers about the potential severe side-effects of quetiapine, and will thus facilitate clinical informed consent for the clinical trial phase of the study. Completion of the first part of the study will also serve as the screening component for part II. Part II includes, first, obtaining written informed consent from eligible subjects, and then randomly assigning them to continue quetiapine or to be switched to trazodone in open-label "real world" fashion for the duration of 4 weeks, followed by another four weeks of open, non-randomized follow- up. The purpose of the second part of the study is to determine if trazodone is an adequate substitute for quetiapine, primarily in terms of treating insomnia. The investigators hypothesize that trazodone will not be inferior to quetiapine in maintaining good quality of sleep measured by sleep scales (i.e., scores will not significantly worsen once switched). This study is open to Veterans in the VA system only. Eligible subjects must have a history of "dual diagnosis" (i.e., a history of addiction and mental illness).

NCT ID: NCT01624831 Terminated - Schizophrenia Clinical Trials

Social Cognition in Longstanding Psychosis

Start date: November 2011
Phase:
Study type: Observational

In the current study, the investigators propose to measure the five domains of social cognition identified by the National Institute of Mental Health (NIMH) as relevant to individuals with psychosis (i.e., theory of mind, attribution style, emotion recognition, social perception, and social knowledge). The investigators will also explore the association between different domains of social cognition and outcomes relevant to psychotic disorder (e.g., symptomatology, social functioning, and vocational functioning).

NCT ID: NCT01324297 Terminated - Schizophrenia Clinical Trials

The Topical Niacin Skin Flush Test in First Episode Psychosis

Start date: December 2011
Phase: Phase 3
Study type: Observational

The purpose of this study is to gather normative data from healthy adults and to determine a sensitive and specific cut-off value for responders and non-responders to the Niacin Skin Flush Test in a sample of first episode psychosis patients.

NCT ID: NCT01310140 Terminated - Clinical trials for Major Depressive Disorder

Risks for Insulin Resistance and Metabolic Syndrome Between Major Depressive Disorder (MDD) or MDD With Psychotic Features

Start date: January 2011
Phase: N/A
Study type: Observational

Studies have shown that people with certain disorders have an increased risk of developing a condition called Metabolic Syndrome (MS). In this study, the investigators want to learn more about MS among people staying in the hospital for treatment of Major Depressive Disorder (MDD) and also Major Depressive Disorder with Psychotic Features (MDpsy). The investigators also want to learn more about a stress hormone called cortisol that is made in the body. Those who take part in this study will answer some questionnaires, be given some psychiatric interviews, and have some blood taken along with a urine sample. The investigators believe that patients in the hospital with MDpsy will have higher baseline rates of MS factors, cortisol levels, dexamethasone non-suppression, and insulin resistance, compared with MDD alone.

NCT ID: NCT01246310 Terminated - Depression Clinical Trials

Myoinositol for the Treatment of Ovarian and Psychiatric Disorder in Polycystic Ovary Syndrome (PCOS) Patients

Start date: November 2010
Phase: N/A
Study type: Interventional

Polycystic ovary syndrome (PCOS) is one of the most common reproductive disorders affecting 5-10% of women of reproductive age. Beside impairments on reproductive functions (oligomenorrhea/amenorrhea), it also affects metabolism (insulin resistance, type 2 diabetes mellitus and cardiovascular risk) and psychology (increased anxiety, depression and eating disorders). Recently, several studies have shown that there is an increased risk of mood disorders in women with PCOS, with major depression and bipolar disorder as the most frequent diagnosis. Myo-inositol is classified as a member of the vitamin B complex and it works as a second messenger system of several neurotransmitter receptors; furthermore, inositol, when administrated at pharmacological doses, crosses the blood-brain barrier. Studies from the 90s showed that inositol, alone or in combination with other antidepressant drugs (mainly serotonin reuptake inhibitors), is able to induce improvement of the Hamilton depression rating Scale. Recently, inositol has been proposed as treatment to improve clinical, metabolic and endocrinal status in PCOS patients. Administration of myo-inositol to PCOs patients resulted in several beneficial effects, such as decrease of circulating insulin and serum total testosterone as well as a restored ovulation. In this proposed study, the investigators aim to evaluate in a double blind randomized trial whether inositol alone has beneficial effects on mental health disorders associated with PCOs. In particular, 60 women in reproductive age that will be diagnosed of PCOs, according to Rotterdam 2003 criteria, will be recruited and randomly assigned to the inositol or placebo group. Both groups will go through ultrasonic evaluation of the ovaries and serum hormonal levels (FSH, LH, testosterone, estradiol and insulin) will be evaluated. Furthermore, with the help of psychiatrics, patients will be interviewed in order to test the presence of any mental health disorders using validated tests such as: Hamilton Anxiety Scale (HAM-A), Hamilton Rating Scale for Depression (HAM-D), Health Assessment Questionnaire (HAQ), Short Form of Mc Gill Pain Questionnaire (SF-MPQ). Women assigned to the inositol group will receive 12g of inositol during the day in three different administrations for a period of 4weeks. At the end of treatment period patients will be interviewed by psychiatrics and will go through ultrasonic evaluation of the ovaries and hormonal levels will be tested
