Active clinical trials for "Schizophrenia"

The primary purpose of the study is to assess the safety and tolerability of a long-acting injectable formulation of risperidone when switching from an oral antipsychotic in patients with schizophrenia.

The purpose of this study is to compare the effectiveness, tolerability, and efficacy of the currently available atypical antipsychotic drugs olanzapine (2.5-20 mg/day), quetiapine (100-800 mg/day) and risperidone (0.5-4 mg/day) in patients with schizophrenia, schizophreniform disorder, or schizoaffective disorder who are experiencing their first psychotic episode.

The purpose of this study is to evaluate the efficacy of the drug SM-13496 compared to a placebo and to haloperidol in patients with schizophrenia.

The purpose of this study is to test the effectiveness of a family-centered, community-based, self-management intervention (Self-Management Therapy) for adolescents with schizophrenia. The study will test the intervention's effectiveness in improving the adolescents' behavior, thinking, mood, and use of substances such as drugs and alcohol. The study also will look at the effects of the patient on the family. The intervention involves training in recognizing symptoms of schizophrenia and in stress management, problem-solving, and social skills. Parents and siblings are included to gain knowledge and skills to support the adolescents. The Self-Management Therapy intervention is administered in small multiple-family groups in 12 sessions over 7-1/2 months. The effects of the intervention on the patient and his/her family are assessed prior to treatment, after 6 sessions, after 12 sessions, and in a follow-up visit 6 months after completion of sessions. A child may be eligible for this study if he/she: Is 15 to 19 years old and has been diagnosed with schizophrenia.

Genetic analyses conducted on patient with psychiatric disorders assessed at the expert centres resulted in the identific action of genetic variants associated with psychiatric disorders (Courtois, 2020). These data require further genetic and functional analyses. The first objective of this study is to investigate the disease-related inheritance of genetic variants in the families of individuals in whom these variants have been identified. The second objective is to explore the functional consequences of disease-associated genetic variants in patients cells and those of their relatives with and without these variants. The present project aims to enrich existing biocollections with DNA from blood or saliva from relatives of patients identified with genetic variants. In addition, we wish to collect hair follicules from patients with identified genetic variants of interest and their family members who wish to participate in the study. These hair samples with SNA will be used to dedifferentiate the isolated cells into induced pluripotent stem cells (IPSCs), and then to differentiate them into cells expressing the gene of interest, such as neurons or astrocytes, or into more complex systems, such as brain organoids.

This study aims to provide an evidence-based behavioral intervention to reduce violent behavior for individuals experiencing early psychosis.

The Lost Children Society (LCS) is a Therapeutic TableTop Role-Playing Game specifically developed for early-onset schizophrenia patient. It is performed online via a secure teleconsultation and videoconference platform. Patients are connected from their home, on their personal computer or tablet, equipped with headsets with microphone. This study aims to validate the feasibility of this online Therapeutic TableTop Role Playing Game.

This is an Open-Label, One-Sequence Study to Evaluate the Steady- State Comparative Bioavailability of Intramuscular Risperidone ISM® and EU Risperdal® (Sourced From Germany).

This trial attempts to evaluate the effects of intensive transcranial direct-current stimulation (tDCS) on improving cognition in schizophrenia patients and changes in resting state brain network connectivity, especially increasing connectivity in the tasks related network, and increasing activation the DLPFC in a working memory task. Half of the participants will be randomized to tDCS group, while the other half will be randomized to receive sham tDCS.

The goal of this project is to evaluate an innovative psychosocial intervention package that will incorporate evidence-based treatment strategies to target the affective-motivational deficits, negative expectancies, and behavioral skills deficits that are central to the maintenance of negative symptoms. The intervention - called EnCoRE (Engaging in Community Roles and Experiences) - will include strategies aimed at teaching Veterans with schizophrenia and negative symptoms ways to (1) overcome deficits in anticipatory pleasure, (2) increase intrinsic motivation for goal-directed activities, (3) reduce expectancies for failure, and (4) perform skillfully in new social situations, all of which can impact implementation of new skills and behaviors. Rather than develop a new set of intervention strategies, the investigators will include within EnCoRE evidence-based strategies for these treatment domains. In addition, the investigators will collect qualitative information both from Veterans concerning their perceptions of the strengths, weaknesses, and barriers to participation in EnCoRE, as well as from a sample of mental health providers who work with Veterans with schizophrenia and negative symptoms, in order to inform a larger scale implementation trial should EnCoRE prove effective here.
