Intensified Pharmacological Treatment for Schizophrenia, Major Depressive Disorder and Bipolar Depression...
Schizophrenia and Related DisordersMajor Depressive Disorder1 moreSchizophrenia, bipolar and major depressive disorders collectively affect over 10 million people across the EU and are associated with annual healthcare and societal costs in excess of 100 billion Euros. When diagnosed with one of these disorders, patients are prescribed psychotropic medication such as antidepressants, mood stabilisers or antipsychotics. It is unknown whether this first-line treatment will be successful. After this first-line treatment fails, usually a second-line treatment is initiated, and when this is not successful either a third-line treatment is initiated. Third-line treatments are quite successful, especially when compared to second-line treatments. The research question is whether the third-line treatments (early-intensified treatments) would be more efficacious than the current second-line treatments (treatment as usual) for schizophrenia, bipolar and major depressive disorders. If this is indeed the case, this could lead to the prevention of unnecessary trials of ineffective treatments and adaptations of worldwide guidelines as well as a reduction of healthcare and societal costs.
Risk Prediction Model of Cardiovascular Events in Patients With Schizophrenia
SchizophreniaSchizophrenia is a serious mental illness that has a great impact on social function. Studies have evidenced that schizophrenia patients live 10-20 years less than general population.It mainly dues to high cardiovascular risk. How to improve patients' survival rates? At present, there is an objective model to assess cardiovascular risk among schizoprenia patients in England - PRIMROSE.But there is a lack of model for schizophrenia patients in china. In order to better guide clinical practice, we are now exploring a domestic cardiovascular risk prediction model to raise people's awareness.
Interest of the Tool: Evaluation of Specific Care in an Ecological Environment for Patients Suffering...
Patients With Schizophrenia-like DisordersThe study use a new ecological questionnaire called ESSME developed by a care team in order to evaluate ecological environment of patients with schizophrenia-like disorders. Indeed, evaluation in an ecological environment would make it possible to be as close as possible to the concerns of theses patients, which could improve the care of this population, by making it possible to set with the patient objectives anchored in their daily life.
Patientheque in Patients With a Psychosis .
Schizophrenia ProdromalSchizophrenia2 moreEstablishment of a patient library for patients who have had a first psychotic episode and who have an "at risk" status for psychotic disorder (GRD, APS, BLIPS group) or a psychosis threshold during CAARMS administration. Samples are taken on inclusion, at 2 years, and if relapse or significant clinical event within 5 years of inclusion, on 250 patients for 10 years.

State Representation in Early Psychosis
PsychosisSchizophrenia2 moreThe purpose of this study is to examine state representation in individuals aged 15-40 who have been diagnosed with a psychotic illness, as well as young adults who do not have a psychiatric diagnosis. State Representation is our ability to process information about our surroundings. The investigators will complete some observational tests as well as a cognitive training clinical trial.
iTBS for Increased Appetite Induced by Antipsychotics
SchizophreniaAntipsychotics are prone to cause metabolic side effects, including weight gain, hyperglycemia, insulin resistance, hyperlipidemia and so on, leading to a 2-3 times higher risk of death in patients with schizophrenia compared to healthy people. Conventional high-frequency rTMS have been used to treat people with obesity and showed certain effectiveness. However, studies involving schizophrenia patients and intermittent theta burst (iTBS) mode are rarely seen. The goal of this clinical trial is to evaluate the efficacy and safety of iTBS on ameliorating increased appetite induced by antipsychotics in people with schizophrenia.
Low-dose Buprenorphine as a Modulator of Social Motivation in Schizophrenia
SchizophreniaLow social motivation is a significant symptom of schizophrenia and is a major cause of disability and suffering for many patients struggling with the illness. Social motivation refers to the drive to participate in or abstain from social activities. Many patients with schizophrenia evidence both decreased drive to seek positive social input (approach motivation) and heightened drive to avoid negative social input (avoidance motivation) compared to individuals without the illness. Despite the enormous burden of these deficits on patients, there are no medications that effectively treat impaired social motivation. Buprenorphine is an unusual drug that is used to treat opioid use disorder at higher doses and more recently, to treat depression and suicidality at lower doses. It is a unique opioid medication that has a compound action that gives it the potential to improve social motivation both by boosting approach motivation and by reducing avoidance motivation. The effects of low doses of buprenorphine have previously. been studied in healthy volunteers, showing that the drug enhances social motivation. These results in nonclinical volunteers suggest that buprenorphine may be a promising treatment for deficits in social motivation seen in some patients with schizophrenia. However, no previous studies have investigated the effects of buprenorphine on social motivation in this population. Here the effects of a low dose of buprenorphine (0.15mg) on social motivation in patients with schizophrenia (N=40) will be assessed. In this double-blind, cross-over, placebo-controlled study, participants will attend a 2-hour preparatory session and two 6-hour laboratory sessions, at which they will receive either placebo or buprenorphine. During expected peak drug effect they will complete validated tasks assessing social motivation. It is expected that buprenorphine will increase approach motivation and decrease avoidance motivation as measured by an attention bias task. The results of this study will lay the foundation for the clinical use of buprenorphine as the first medication to treat social deficits in schizophrenia.
Using Digital Media Advertising to Reduce the Duration of Untreated Psychosis
SchizophreniaFirst Episode PsychosisThere is compelling evidence that longer duration of untreated psychosis independently predicts negative outcomes. The proposal aims to explore whether targeted and proactive online outreach through search engine advertisements, coupled with engaging, informative, and interactive online resources, can effectively reduce the duration of untreated psychosis and facilitate earlier treatment initiation in New York State. Results from this initiative will be critical to informing the subsequent design and conduct of larger, focused, and proactive digital media campaigns targeting patient with FEP and their caregivers online, intended to accelerate linkage to care and reduce the duration of untreated psychosis throughout the U.S.
Imaging Cannabinoid Receptors Using Positron Emission Tomography (PET) Scanning
SchizophreniaCannabis Dependence5 moreThe aim of the present study is to assess the availability of cannabinoid receptors (CB1R) in the human brain. CB1R are present in everyone's brain, regardless of whether or not someone has used cannabis. The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand OMAR, in healthy individuals and several conditions including 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness and 4) individuals with a family history of alcoholism, 5) Post-Traumatic Stress Disorder 6) Opioid Use Disorder using the PET imaging agent or radiotracer, [11C]OMAR. This will allow us to characterize the number and distribution of CB1R in these conditions. It is likely that the list of conditions will be expanded after the collection of pilot data and as new data on cannabinoids receptor function and psychiatric disorders becomes available. Those in the cannabis us disorder arm of the study will have a PET scan on at least three occasions: once while smoking as usual, once after 48-hours of abstinence from cannabis, and a final time after 4 weeks of abstinence. Additional scans may be conducted within the 4 weeks and the last scan may be conducted well beyond 4 weeks. Similarly, while most schizophrenia patients may get scanned just once, a subgroup of patients may get scanned more than once. For example to tease out the effects of medications, unmedicated patients may get scanned while unmedicated and again after treatment with antipsychotic medications. Similarly prodromes may get scanned while in the prodromal stage off medications, on medications and after conversion to schizophrenia.
