Group DBT Skills Training for First Episode Psychosis

Psychosis is a serious mental health condition that can affect how a person thinks, feels, and functions in daily life, often making it harder to maintain relationships, continue education, or work. Even with standard treatment, many people continue to experience emotional distress, depression, anxiety, and difficulty coping with strong emotions. These challenges can worsen recovery, increase the risk of substance use and suicidal behaviour, and place a significant burden on individuals, families, and the healthcare system. Dialectical Behaviour Therapy (DBT) is a skills-based psychological treatment that helps people manage emotions, tolerate distress, and improve relationships. Although DBT has been effective in other mental health conditions, it has not been well studied in people with first-episode psychosis. This study will evaluate an 8-week group DBT skills training adapted for individuals with first-episode psychosis. The study aims to assess whether the program is acceptable and feasible to deliver, and whether it may improve emotion regulation, mood, resilience, and functioning. Findings will inform whether a larger clinical trial of this intervention should be conducted.

Cerebellar Modulation of Cognition in Psychosis

The goal of this clinical trial is to learn about cognition in psychotic disorders (schizophrenia, bipolar disorder, and schizoaffective disorder). The main question it aims to answer is: Can we use magnetic stimulation to change processing speed (how quickly people can solve challenging tasks). Participants will be asked to perform cognitive tasks (problem-solving) and undergo brain scans before and after transcranial magnetic stimulation (TMS). TMS is a way to non-invasively change brain activity. Forms of TMS are FDA-approved to treat depression and obsessive compulsive disorder. In this study, we will use a different form of TMS to temporarily change brain activity to observe how that changes speed in problem-solving.

Comparison of Accelerated Intermittent Theta Burst Stimulation vs High Frequency Transcranial Magnetic Stimulation (Hf-rTMS) on Cognitivesymptoms in Treatment-resistant Schizophrenia

This randomized, double-blind, sham-controlled trial compares three brain stimulation approaches-accelerated intermittent theta burst stimulation (aITBS), high-frequency repetitive transcranial magnetic stimulation (HF-rTMS), and sham stimulation-for treating cognitive deficits in treatment-resistant schizophrenia. Ninety patients receiving clozapine will be randomized 1:1:1 to receive 20 sessions over 4 weeks targeting the dorsolateral prefrontal cortex. The primary outcome is change in cognitive function measured by B-CATS score at 2, 4, and 12 weeks. Secondary outcomes include social cognition, symptom severity, brain metabolism (FDG-PET), and inflammatory biomarkers.

EPI-MINN: Targeting Cognition and Motivation

The purpose of this study is to perform a practice-based research project designed to assess whether cognition and motivated behavior in early psychosis can be addressed as key treatment goals within real-world settings by using a 12-week mobile intervention program. Participants who are enrolled in a chart review study of measurement-based care will be recruited to participate in this study. In the measurement-based care study, participants are enrolled in coordinated specialty care programs for early psychosis that provide comprehensive clinical services such as psychotherapy, medication management, psychoeducation, work or education support, and measurement-based care. Participants will complete a set of well-defined measures every 6 months that assess symptoms, functioning, cognition and motivation as standard of care. The current study will utilize the data acquired in the measurement-based care study. The aim of this study is to investigate a well-defined 12-week mobile intervention program specifically designed to target cognitive functioning and motivated behavior for individuals with early psychosis. The investigators will test for differences in the clinical trajectories over 18 months in those who receive the intervention vs. those who do not. This study will be conducted jointly with a sister protocol under a separate NCT listing. This iteration will be conducted locally within the EPI-MINN Network, while the other project will be conducted on a national scale.

Investigating the Effect of a Single-dose of Levetiracetam on Brain Function, Chemistry and Cognitive Performance in Psychosis Risk

Background Psychosis is a mental health condition that affects around 3 in 100 people in their lifetime. Most treatments for psychosis target a brain chemical called dopamine but they don't work for everyone and don't address many of the symptoms. People with psychosis and people at risk of developing psychosis show differences in a part of the brain called the hippocampus, such as smaller size and increased activity. This hyperactivity may be associated with cognitive difficulties (thinking and memory). The basis of this hippocampal hyperactivity is thought to be a deficit in excitation and inhibition of brain cells. Excitation causes brain cells to send signals more frequently, and inhibition causes cells to send signals less frequently. A balance between these signals is important for the brain, including the hippocampus, to function properly. Approach Levetiracetam is a medication that is widely used to treat epilepsy and which helps balance excitation-inhibition in the brain. We will use brain imaging, using Magnetic Resonance Imaging (MRI), to test if levetiracetam can help reduce hippocampal hyperactivity, alter connectivity and change levels of brain chemicals in people who are at risk of developing psychosis. Participants (18-40 years), identified as at risk of psychosis through the Outreach and Support in South London (OASIS) teams, will attend an initial visit at the Institute of Psychiatry, Psychology \& Neuroscience. This will involve questions about experiences and feelings, assessment of thinking and memory, and a blood test. They will then attend two scanning visits at the Centre for Neuroimaging Sciences, during which they will take capsules of either levetiracetam or placebo (in a randomised order) before having a 60 mins MRI scan. The MRI scan will look at blood flow to the hippocampus, resting activity, activity during a cognitive task and levels of brain chemicals. A case-control sample of 33 healthy individuals aged 18-40 will be recruited from Greater London. We will recruit a healthy control (HC) sample to establish the presence of hippocampal dysfunction in our CHR-P group by comparing the MRI data for CHR-P under the placebo condition with that of the HC sample. The HC individuals will attend the screening visit and one scanning visit. They will not receive any medication. Funded by the Wellcome Trust and conducted by King's College London researchers, the study spans 2-3 months per participant. Impact Our study will provide important evidence about how levetiracetam affects brain function, and how this relates to cognition. This knowledge may lead to innovative approaches for understanding and treating psychosis early.

Cognitive Strategies in Early Psychosis 2

The goal of this clinical trial is to learn more about decision making in psychosis spectrum disorders, like schizophrenia. Participants will be people who have had symptoms of a psychosis spectrum disorder start within the last five years. The investigators will study how two study agents change decision making in people with psychosis, by asking participants to complete some brain games on the computer before and after taking the study agents. The investigators hope to improve our understanding of psychosis to help people in the future. The main research questions are: * Does a single dose of modafinil change how people with psychosis play the brain games? * Does a single dose of d-serine change how people with psychosis play the brain games? * Does a single dose of modafinil change brain activity? * Does a single dose of d-serine change brain activity? Participants will: * Complete an interview and self-report questionnaires. * Complete safety screening activities, like a blood draw, a urine drug test, and an alcohol breathalyzer test. * Complete functional Magnetic Resonance Imaging (fMRI) scans. fMRI uses magnets to take pictures of the brain. There will be six scanning appointments in the study, with two scans each. Appointments will be about a month apart. * Take a single dose of a study agent during each scanning appointment. The study agent will be taken after the first fMRI. There are three study agents in total: modafinil, d-serine, and a placebo. Each participant will take each study agent twice during the study. * Play brain games on a computer that measure decision making, thinking, and problem solving skills

Neurobehavioral Mechanisms of Social Isolation and Loneliness in Serious Mental Illness

The proposed research will test the hypothesis that objective social isolation and loneliness are linked to neurobehavioral mechanisms involved in social perception and motivation in individuals with and without serious mental illness. Moreover, it will investigate the specific dynamic interactions among these experiences in daily life and how they, and their neurobehavioral predictors, are linked to day-to-day functioning. The findings of this project could provide novel targets for therapeutics aimed at improving functioning and overall quality of life in individuals with serious mental illnesses, as well as quantitative phenotypes for use in early detection efforts.

Mentalization Based Treatment (MBT) in Help Seeking Youths With a Clinical High-Risk Condition for Psychosis (CHR-P)

The primary objective of this study is to evaluate the efficacy of Mentalization-Based Treatment (MBT) combined with Need-Based Clinical Interventions (NBCI) compared to NBCI alone, on CHR-P diagnostic statuses and symptom expression (Hypothesis 1). Specifically, the investigator will assess diagnostic outcomes using a 3-level variable: transition to psychosis, CHR-P status quo, and remission out of CHR-P, as well as CHR-P symptom expression. The investigator hypothesize that: (1a) the experimental treatment (MBT + NBCI) will have a significant effect on diagnostic status (i.e. transition to psychosis) at the end of treatment and follow-up; (1b) the experimental treatment (MBT + NBCI) will significantly reduce the severity of psychotic symptoms at the end of treatment and follow-up.

Precision Brain Stimulation to Reduce Cannabis Craving in Schizophrenia

The central hypothesis is this: Brain circuits most relevant to cannabis use in schizophrenia are distinct from pathways identified in healthy controls who use cannabis. This study seeks to provide evidence that targeted stimulation of the DMN leads to both altered network activity and a concomitant behavioral change in cue-induced craving and cognitive performance in individuals with schizophrenia and schizoaffective disorder, while targeted stimulation of the L DLPFC leads to these changes in healthy controls who use cannabis. This study will test a model that integrates brain network pathophysiology and cognition to 1) explain the prevalence of cannabis use in schizophrenia and 2) identify a target for engagement in schizophrenia. This study seeks to establish a neuroscientific framework to guide future treatment-oriented studies aimed at reducing craving and improving cognitive performance in individuals with schizophrenia and schizoaffective disorder. This is a study of the effect of 2 rTMS interventions on functional connectivity and craving in individuals with schizophrenia or schizoaffective disorder and healthy controls who use cannabis. Aim 1: Target Engagement: Determine if rTMS manipulates functional connectivity of each target (DMN, L DLPFC) (n=100). Aim 2: Clinical Efficacy: Determine if rTMS affects cue-induced craving and if craving change correlates with change in functional connectivity (n=100). As an exploratory analysis, the factors that explain individual variance in rTMS-induced connectivity change will also be explored.

Strengthening Care in Collaboration With People With Lived Experience of Psychosis in Uganda

Background: Mental health services are most effective and equitable when designed, delivered, and evaluated in collaboration with people with lived experience of mental health conditions. Unfortunately, people with lived experience are rarely involved in health systems strengthening or are limited to specific components (e.g., peer helpers) rather than multi-tiered collaboration in the continuum of health services (e.g., ranging from home- to community- to clinic-based services). Moreover, programs that do involve people with lived experience, typically involve people with a history of a substance use conditions or common mental disorders. In contrast, the collaboration of people with lived experience of psychosis is especially rare. A pilot cluster randomized controlled trial will be conducted in urban and peri-urban areas around Kampala, Uganda, to evaluate the benefits of an implementation strategy for mental health services with engagement of people with lived experience of psychosis throughout the home-to-community-to-clinic care continuum, this is a hybrid type-III implementation-effectiveness pilot focusing on the differences in implementation strategy. This implementation strategy, entitled "Strengthening CAre in collaboration with People with lived Experience of psychosis in Uganda", will include training people with lived experience of psychosis using PhotoVoice and other methods to participate at three levels: in-home services, community engagement, and primary health care facilities. The investigators will compare a standard task-sharing implementation arm using training by mental health specialists with an experimental implementation arm that includes collaboration with people with lived experience. The primary objective is to evaluate the feasibility and acceptability of this strategy in the context of assuring safety and wellbeing of people with lived experience of psychosis who collaborate in health systems strengthening. By collaborating on health systems strengthening across these multiple levels, we foresee a more in-depth contribution that can lead to rethinking how best to design and deliver care for people with lived experience of psychosis. Successful completion of this pilot will be the foundation for a fully powered trial to evaluate the benefits of multi-level collaboration with people with lived experience of psychosis.
