Active clinical trials for "Schizophrenia"

The aim of the present single-blind randomized-controlled therapy study is to assess the efficacy of a new form of Cognitive Behavioral Therapy for delusions with a focus on emotion regulation, improvement of self-esteem and sleep quality (CBTd-E).

This is a multicenter, randomized, double-blind, placebo-controlled, three period crossover study to evaluate the effects of RO5545965 on the functioning of key brain circuitry involved in negative symptoms using functional magnetic resonance imaging (fMRI) and reward-based learning in stable participants with mild to moderate negative symptoms of schizophrenia treated with antipsychotics. Participants will be randomized to one of six different sequences during which each participant will receive three 3-week treatment courses with RO5545965 5 milligrams (mg), RO5545965 15 mg and placebo. Each treatment period will be separated by a washout period of 14 days. Total duration of study will be approximately 17 weeks.

This clinical trial tests the feasibility, effectiveness and patient satisfaction with cognitive remediation therapy for patients diagnosed with schizophrenia or schizoaffective disorder within a forensic hospital. It is hypothesised that patients receiving cognitive remediation therapy will have an improvement in cognitive performance, real world functioning, symptoms, violence risk and benefit more from additional psychosocial treatment programmes over time relative to patients receiving treatment as usual. Furthermore it is hypothesised that it will be feasible to carry out such a study and that patients will report high rates of satisfaction with cognitive remediation therapy. Finally it is hypothesised that differences on the effectiveness measures will be maintained at 6 month follow up after the end of treatment.

To test the effectiveness of Acceptance and Commitment Therapy (ACT) versus enhanced Treatment as Usual (eTAU) delivered by hospital staff for inpatients with psychotic-spectrum disorders.

The purpose of this PET study is to verify the binding of Lu AF35700 after multiple oral dosing at the dopamine and the serotonin receptors in male patients with schizophrenia.

This study aims to evaluate a novel group psychological intervention targeting anxiety triggered by urban environments for people with paranoia.

The purpose of this study is to assess the efficacy of d-cycloserine (DCS) as an augmentation strategy in two psychotic patients with a triplication (4 copies) of the glycine decarboxylase (GLDC) gene. Subjects will first undergo an eight-week open-label arm of treatment with DCS (50 mg/d) followed by six 6-week double-blind placebo-controlled exposures to DCS or placebo. The length of each double-blind arm is limited to six weeks to minimize the length of symptom exacerbation experienced by the subjects when they are receiving placebo. The randomization scheme will allow two consecutive exposures to DCS, but will not allow two consecutive exposures to placebo, again to minimize the length of any symptom exacerbation. At the end of the open-label DCS trial, the following procedures will be carried out: structural MRI (3T), proton 1H MRS (4T), fMRI (3T), steady-state auditory evoked potentials, and electroretinogram recordings. In addition, 1H MRS (4T) for 2 hours after a single oral dose of a DCS will be assessed. Baseline data on all of these measures were previously obtained as part of a different study registered in clinical trials.gov - NCT01720316). Positive, negative, and affective symptoms and neurocognitive function as well as plasma levels of large neutral and large and small neutral and excitatory amino acids and psychotropic drug levels will be assessed periodically. Pharmaceutical grade DCS) or placebo will be compounded and dispensed by the McLean Hospital Pharmacy. The investigators hypothesize that mutation carriers will have reduced endogenous brain glycine and GABA levels and increased brain glutamate and glutamine levels. DCS administration will increase brain glycine in the two carriers compared to baseline and treatment with glycine (0.8g/kg). The investigators hypothesize reduced activation of magnocellular pathways and abnormal ERPs modulated by NMDA in mutation carriers compared with non-carrier family members and controls. . The investigators hypothesize that DCS, but not placebo, will improve positive, negative and affective symptoms as well as neurocognitive function. The investigators also hypothesize that DCS will improve clinical and cognitive functioning, will partially normalize decreased baseline glycine and GABA and increased glutamate and glutamine, and will partially normalize magnocellular pathway activation and abnormal evoked potentials.

This study evaluates the addition of psychoeducation to treatment as usual in the treatment of adults with schizophrenia for relapse prevention. Half of participants will receive a brief (5 sessions) psychoeducation intervention and treatment as usual in combination, while the other half will receive treatment as usual only.

The study aimed to investigate the effects of bimodal anodal transcranial direct current stimulation (tDCS) over bilateral dorsolateral prefrontal cortex (DLPFC) on psychopathological symptoms, insight, psychosocial functioning, neurocognitive function and heart rate variability (HRV) in schizophrenia patients

This is a clinical trial that intend to determine the effects of S-ketamine on event-related potentials associated with semantic affective pain-processing
