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).
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.
Serious mental illnesses are all chronic illnesses such as schizophrenia, schizoaffective disorder, and other psychotic disorders, major depression, and bipolar disorder, which cause impaired functioning in areas such as activities of daily living, self-care, social relationships, professional and academic life, quality time, etc. These chronic illnesses are a significant source of stress for the patient and family members. With the transition to community-based practices in the care of chronic mental illnesses, t he duties of families have increased and as a result, have had significant negative effects on caregiver and family functioning. Caregivers face many challenges and these challenges cause caregivers to experience feelings such as anxiety, stress, fear, guilt, helplessness, hopelessness, powerlessness, loss, and anger. It is understood that families are in significant need of psychosocial support interventions that will enable them to develop effective coping methods and reduce stress and anxiety. Themotivationall Interviewing Technique is one of the methods that can be applied to the caregivers of individuals diagnosed with chronic mental illness to adapt to the situation and cope with the difficulties they experience. Motivational Interviewing does not deal with issues such as teaching new information or ensuring acceptance of the past. It focuses on the individual's current stress, anxiety and dilemmas, goals, and plans. Studies show that any intervention that will contribute to the caregiver's coping attitude and psychological distress level will also support the empowerment of the sick individual. For this purpose, the study was planned to determine the effect of motivational interviewing intervention for caregivers of individuals with serious mental disorders on psychological distress and coping attitudes.
This is a single-arm pilot study to examine the impact of BXCL501 (sublingual film formulation of dexmedetomidine) administration on reducing the severity of undifferentiated acute agitation in patients presenting to the emergency department with underlying bipolar disorder or schizophrenia. This study is designed to evaluate BXCL501 for its FDA-approved indication -- treatment of agitation associated with bipolar disorder or schizophrenia -- applied in the emergency department setting.
