Filter by: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. 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.
This 52-week, open-label extension study is to evaluate the long-term safety and tolerability of ACP-204 in subjects with ADP.
The purpose of this study is to see how feasible is the use of compact EEG and paired audio technology to administer sleep interventions for inpatients with psychosis, to see if individuals that receive individualized technology-based sleep interventions experience improvements in sleep quality and to see if individuals that receive individualized technology-based sleep interventions experience improvements in symptomatology
The proposed clinical trial aims to examine the efficacy of an online-based self-help intervention for auditory hallucinations in persons with psychotic disorders. The intervention is primarily based on Metacognitive Training (MKT) and Mindfulness-Based Group Therapy (MBGT). The investigators will utilize a mixed-method study design within a randomized controlled trial. The intervention group will be compared with a waitlist-control group (WL-TAU). Both study conditions are allowed to continue standard scheduled treatment. The aim is to analyze the efficacy of and the subjective satisfaction with the intervention, based on self-report assessments evaluated from baseline (T0) to post-intervention after 6 weeks (T1).
This study aims to test the feasibility and acceptability of a brief behavioral intervention that combines two treatments, Motivational Interviewing (MI) and Cognitive Behavioral Therapy (CBT), that have been shown to work in prior research studies. The format of the intervention will be a combination of in-person sessions and remote elements delivered via mobile phone (together called MI-CBTech). The goal of the intervention is to improve community integration in Veterans with serious mental illness (SMI) who have experienced homelessness. A time- and format-matched control arm will include remote mindfulness training. 50 Veterans with SMI experiencing homelessness will be randomized to one of the two arms (25 per arm).
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.
SchizOMICS is a Phase IV, multicenter, dose-flexible, open-label, randomized controlled clinical trial to evaluate the efficacy and safety of aripiprazole versus paliperidone using multi-omics data in patients with a first psychotic episode. The trial will include a total of 244 patients, with two arms of treatment with paliperidone and aripiprazole (1:1). The main objectives of the study are: 1. To compare the efficacy and safety of aripiprazole and paliperidone in the treatment of first episode psychosis (FEP) subjects in real-world clinical settings at 3 months. 2. To elucidate whether non-responders after 3 months of adequate treatment may display different molecular signatures at baseline based on multi omics data and systems biology analysis. 3. To uncover whether the appearance of side effects after 1 year of adequate treatment may be related to different molecular signatures based on multi-omics data and lifestyle phenotype using systems biology analysis.
Psychotic illnesses are characterised by hallucinations, delusions, and disturbed thoughts; symptoms associated with high personal and societal costs. Despite the efficacy of antipsychotic medication, approximately 84% of patients experience at least one relapse within 36 months of their first episode. Thus, identifying patients who will relapse and who will not, and then providing specific treatment to patients who are more likely to relapse is clinically meaningful. Belief-updating and speech are promising markers to predict first episode psychosis (FEP) patients future relapse outcome, as there has been evidence linking these two markers with the onset and progression of psychotic symptoms. The present study will collect cognitive measures relating to belief-updating and speech in patients with FEP at baseline, and build models to predict relapse based on these measures. Belief updating tasks include simple video games (escaping from a planet in the Space Task and a reversal learning task). To collect speech, participants will be asked to describe ambiguous pictures. The study uses a naturalistic follow-up design; data will be collected from 140 FEP patients recruited from local clinical teams and 100 healthy controls recruited from advertisements. Cognitive tasks will be conducted via an online platform Gorilla using participants' own device (e.g. computer, laptop, smartphone and tablet). Clinical interviews can take place either online or face-to-face. Participants will attend three assessments in total, at baseline and at 6-month and 12-month follow-up. Each visit will comprise two components 1) cognitive tasks (45-60 minutes) and basic demographics, 2) clinical interviews.
Lithium is a drug used to treat several psychiatric illnesses. This medication requires particular vigilance because it has a narrow therapeutic margin: the dose necessary to obtain an effective treatment is close to the toxic dose. The blood dosage of the drug and the patient's knowledge of the drug are necessary to optimize and secure the drug intake. The objective of this observational study is to confirm that the score obtained by the LKT lithium knowledge self-questionnaire translated into French is representative of the knowledge of patients treated with lithium. Participants will be asked to complete this questionnaire twice, and the scores obtained will be compared to the blood lithium level to see if a good score is associated with an effective blood lithium concentration.
Deficiencies in social cognition are part of the core symptomatology of psychotic disorders. And deficiencies in social cognition, the closely related concept of metacognition, and, for example, paranoid attitudes are all associated with violence. The link between social cognition and violence is also observed through rehabilitation, as both group-based Social Cognition Interaction Training (SCIT) and group-based Metacognitive Skills Training (MCT) have reduced violent behavior in patients with psychotic disorders. Thus, a better knowledge of social cognition and its rehabilitation in psychotic disorders can help to reduce risky behavior and to rehabilitate the significant social difficulties often found in psychotic disorders. This research study aims to examine factors underlying the efficacy of group-based MCT. The goal of the metacognitive skills training group developed by Moritz and partners is to strengthen the social and metacognitive skills of the patients participating in the group. The group consists of 10 sessions during which exercises and discussion are emphasized. The themes of the group sessions are, for example, jumping to conclusions -bias, empathy, and memory. Detailed information is available from the MCT website (https://clinical-neuropsychology.de/metacognitive_training-psychosis/). Overall there is meta-analysis-level evidence for the moderate effectiveness of MCT on positive symptoms of psychotic illnesses, such as delusions. Prior studies have argued that the unique factor underpinning MCT's efficacy is its impact on various cognitive biases, and that participating in the group especially reduces patients' tendency to jump to conclusions, which is a cognitive style associated with delusions and deficits in social perception and reasoning. As delusionality is related to the risk of violence, these results form a logical link between jumping to conclusions, delusionality, and violence. But the results regarding the effectiveness of MCT are still somewhat conflicting, and studies seem to be of varying quality. Additional longitudinal research and research related to the jumping to conclusion bias are also needed. The hypothesis regarding this study is that the MCT group reduces patients' tendency to jump to conclusions. These reductions are presumed to be associated in one-year follow-up with fewer mood symptoms, delusions, paranoia, and more psychological flexibility.
