Schizophrenia Clinical Trials

In this study, the investigators will examine whether a type of repetitive transcranial magnetic stimulation called accelerated intermittent theta burst stimulation (iTBS) can augment neurocognition in individuals who receive treatment with clozapine. Following a baseline evaluation and magnetic resonance imaging (MRI), participants will undergo a session of iTBS +MRI and session of sham delivery + MRI. The order for these sessions will be blinded and randomized. The investigators predict that accelerated iTBS will enhance neurocognition relative to sham delivery. Read Less

The goal of this clinical trial is to compare engagement in treatment in coordinated specialty care (CSC) to five extra care elements (CSC 2.0) in first-episode psychosis. The main question it aims to answer is: • Does the addition of certain elements of care increase the number of visits in treatment for first-episode psychosis? Participants will either: * Receive care as usual (CSC) or * Receive care as usual (CSC) plus five additional care elements (CSC 2.0): 1. Individual peer support 2. Digital outreach 3. Care coordination 4. Multi-family group therapy 5. Cognitive remediation Researchers will compare the standard of care (CSC) to CSC 2.0 to see if participants receiving CSC 2.0 have more visits to their clinic in their first year. Read Less

The proposed project is based on the observation that schizophrenia is characterized by a chronic pro-inflammatory state, which contributes to the severity of a number of the clinical manifestations of the illness, including cognitive impairments, the treatment of which represents a critically important unmet therapeutic need.

The purpose of this study is to evaluate Community Reinforcement and Family Training for Early Psychosis (CRAFT-EP) for families experiencing early psychosis and substance use delivered exclusively or primarily via telehealth (video conferencing). Read Less

In this study, the investigators will examine whether a deprescription of unnecessary anticholinergic drugs (benztropine or trihexyphenidyl) can augment quality of life, functioning, and neurocognition in individuals who with schizophrenia. Individuals identified by clinical services who have unneeded prescriptions benztropine or trihexyphenidyl will be eligible for deprescription and study entry. Following a baseline evaluation and magnetic resonance imaging (MRI), participants will will be randomized to either staying on their anticholinergic drugs or undergoing deprescription per routine clinical care, and will undergo follow-up evaluations across 6 months. The investigators predict that reducing and deprescribing these drug, if clinically determined to be unnecessary will will enhance functioning, neurocognition Read Less

The current study examines the efficacy of a cognitive training intervention for improving emotion regulation in psychotic disorders. it is hypothesized that the cognitive training program will enhance prefrontal activation, leading to enhanced emotion regulation. Read Less

Participants will receive Transcranial Magnetic Stimulation (TMS) at a random location in the left prefrontal cortex, excluding sites that are potentially unsafe. Extensive behavioral testing will be conducted to determine which behaviors are modulated by stimulating which circuits. Read Less

Patients with schizophrenia spectrum disorder (SSD) will be exposed to active and sham repetitive transcranial magnetic stimulation (rTMS) in separate sessions. SSD-related biomarkers will be assessed before and after the rTMS administration. Read Less

Cannabis is widely used worldwide and is associated with negative outcomes including cannabis use disorder (CanUD), psychosis, and cognitive impairment amongst others. Given the legalization of "recreational" and "medical" cannabis globally, the increasing availability of cannabis, the higher potency of cannabis, the availability of highly potent cannabinoid products, the commercialization of cannabis, and the rising rates of cannabis use, it is critical to understand how genetic factors influence 1) an individual's vulnerability for addiction and psychosis, 2) the response to cannabinoids, 3) the response to novel treatments for CanUD. CanUD is strongly genetically influenced; the investigators published the first CanUD genomewide association study (GWAS) with genomewide-significant results; however, the precise nature of the contribution of genetic factors in the development of CanUD is still not clear. Cannabis exposure has also been linked to a number of psychosis outcomes including schizophrenia (SCZ). SCZ is highly heritable and population-based and genetics studies both support a bidirectional genetic relationship between SCZ and CanUD. However, the precise contribution of genetic factors in the development of psychosis outcomes related to cannabis are not clear. Read Less

The purpose of this study is to examine whether cerebellar stimulation can be used to improve cognitive deficits and mood in patients with schizophrenia, autism, bipolar disorder, Parkinson's disease, and major depression. Read Less

The participants in the study will receive psychiatric treatment at the UCLA Aftercare Research Program. All participants in this 12-month RCT will receive cognitive training. Half of the patients will also be randomly assigned to the aerobic exercise and strength training condition, and the other half will be randomly assigned to the Healthy Living Group condition. The primary outcome measures are improvement in cognition and level of engagement in the in-group and at-home exercise sessions. Increases in the level of the patient's serum brain-derived neurotropic factor (specifically Mature BDNF) which causes greater brain neuroplasticity and is indicator of engagement in aerobic exercise, will be measured early in the treatment phase in order to confirm engagement of this target. In order to demonstrate the feasibility and portability of this intervention outside of academic research programs, the interventions will be provided via videoconferencing. The proposed study will incorporate additional methods to maximize participation in the exercise condition, including the use of the Moderated Online Social Therapy (MOST) platform to enhance motivation for treatment based on Self-Determination Theory principles, and a "bridging" group to help the participants generalize gains to everyday functioning. In addition, the exercise group participants will receive personally tailored text reminders to exercise. Read Less

The goal of this clinical trial is to learn if attention and ways of thinking impact decision-making and brain processes related to decision-making in people with schizophrenia or schizoaffective disorder relative to people without either condition. It will also learn how brain functioning during decision-making relates to real-world decisions made during daily life. The main questions it aims to answer are: * Does paying attention to specific information impact decision-making and brain processes? * Does thinking in a certain way according to specific 'thinking strategies' improve brain processes related to decision-making? * Does brain functioning during decision-making relate to real-world choices to engage in activities? Researchers will compare brain functioning and decision-making on computer tasks of gambling after participants have been trained to use a positive thinking strategy. They will compare what is different in the brain and behavior when participants use this strategy and when they do not. Participants will also answer brief surveys about activities and feelings for a week in their daily lives. Participants will: * Complete several hours of clinical interviewing, cognitive tests, and surveys of about symptoms, experiences, and personality * Complete computer tasks about gambling decisions during MRI brain scanning and while having their visual attention measured using eye-tracking * Complete brief surveys about their activities and feelings 5 times a day for 1 week using a cell phone. Each survey only take several minutes. Read Less
