First-Episode Psychosis

This proposal aims to establish a Digital Laboratory focused on advancing help-seeking and expediting treatment initiation in youth ages 12-29 who are at Clinical High-Risk (CHR) for developing psychosis. Leveraging the Health Action Process Approach (HAPA) model, this study will identify help-seeking subtypes in 25,000 youth who screen positive for psychosis-risk on Mental Health America's national online screening platform, iteratively develop and test theory and data-driven, personalized strategies to advance help-seeking using Micro-Randomized Trials and a Sequential Multiple Assignment Randomized Trial, identify the most accurate CHR screening threshold in an online environment, and link youth, when indicated, to local clinical care via AMP-SCZ, a NIH funded national network of CHR programs throughout the US. This academic-industry partnership aims to curate one of the largest datasets of youth with CHR, and to develop effective strategies to enhance early help-seeking, in a population where help-seeking is critical and a significant barrier to care.

FEEL-GOOD is a prospective multi-site single-blinded randomized controlled trial in young inpatients with acute early psychosis. Participants are randomized 1:1 to FEEL-GOOD plus treatment as usual (TAU) or TAU alone. The intervention consists of one individual preparatory session and eight modularized group sessions delivered over four weeks involving four to eight participants at each session and including practice and homework tasks. Outcomes are assessed at baseline, 4 weeks post-intervention, and 6 months follow-up, with the primary outcome being observer-rated total psychopathology as measured with the assessed by the total score of the Positive and Negative Syndrome Scale (PANSS) post-treatment (4 weeks post baseline).

Psychosis is a severe, common, and disabling psychological disorder. An epidemiological study conducted in England reported an incidence of 34 new cases per 100,000 person-years, with a peak between 16 and 19 years of age. Following a first psychotic episode, two clinical evolutions are possible: thymic psychosis (17%) and non thymic psychosis (83%). The first includes bipolar disorders with a psychotic component and major depressive disorders with a psychotic component; the second, other psychotic disorders, mainly schizophrenia. One of the major difficulties encountered is the frequent impossibility of specifying the type of psychosis at the beginning of the psychotic episode. However, these disorders require different therapies, particularly medication. This leads to a delay in diagnosis with a high risk of relapse. The semiological study of these diseases being carried out within the framework of interviews, it seems interesting to be able to record these and to obtain a quantitative and objective measurement through the study of language. The use of machine learning has made it possible to distinguish patients with schizophrenia from those with bipolar disorder by graphical analysis of language in a more efficient way than with clinical scales.Moreover, it is possible to identify linguistic markers: thus, an alteration of syntactic structures and prosody would be more present in non-thymic than in thymic psychoses. Paraclinical markers are also emerging. In particular, the link between inflammation and mental disorders.For example, an increase in IL-8 has been found only in thymic psychoses. In this context, it seems essential to be able to distinguish these disorders as early as possible through the combined use of clinical and paraclinical markers, and to be able to better understand their pathophysiology.

The RECAP project will evaluate the clinical and metabolic effects of adding exogenous ketones to antipsychotic (AP) treatment in young adults with a first episode of psychosis (FEP). FEP requires early intervention to limit relapse, chronic symptoms, cognitive decline, and reduced life expectancy. Symptoms include positive (hallucinations, delusions), negative (amotivation, anhedonia), cognitive (attention, working memory), and mood disturbances. Standard care combines second- or third-generation APs with psychosocial interventions. However, many patients have persistent symptoms despite optimal treatment. Psychosis is linked to increased cardiovascular and obesity risk. APs can cause insulin resistance, type 2 diabetes, and dyslipidemia, but some metabolic abnormalities-both systemic and cerebral-may precede AP use, suggesting an intrinsic metabolic dysfunction. Brain energy metabolism is often impaired, with altered insulin signaling, glucose transport, and ATP production. Glucose hypometabolism in the prefrontal cortex correlates with negative and cognitive symptoms, even before medication, resembling patterns in Alzheimer's, bipolar disorder, and depression. Ketones, especially beta-hydroxybutyrate, provide an alternative to glucose for brain energy. Ketogenic diets have therapeutic potential but are difficult to maintain, particularly in psychiatric populations. Exogenous ketones, such as medium-chain triglycerides (MCTs), can raise circulating ketone levels without major dietary changes. MCT supplementation has been shown to improve brain metabolism and cognition in other conditions, but no studies have tested it in FEP. This uncontrolled, prospective pilot study will provide 15 g of MCT oil twice daily for 12 weeks, in addition to participants' usual diet and treatment. The primary objective is to assess changes in circulating ketone levels and metabolic markers (glucose, insulin, HbA1c). Secondary objectives include feasibility, acceptability, effects on real-time glucose metabolism (via continuous glucose monitoring), clinical symptoms (negative, cognitive), quality of life, other metabolic biomarkers, and general systemic markers. This is the first study to test exogenous ketones in FEP. It will assess safety, tolerability, and potential metabolic and clinical benefits, offering preliminary mechanistic insights and guiding future integrative mental health strategies.

Single-blind, randomized controlled trial of normobaric oxygen therapy among individuals with first-episode psychosis: Effects on symptomatology and cognition.

This study will evaluate a program called On Track for Wellness (OTW) which is being adopted by the Illinois Department of Human Services' Division of Behavioral Health \& Recovery (DBHR) for use in all state-funded early psychosis programs in Illinois. OTW combines use of Fitbit activity trackers with health education, goal setting to promote health activation, and ongoing support for maintaining healthy lifestyles. Successful completion of this research will gauge the effectiveness of this program in improving sleep hygiene and increasing physical activity among people recently diagnosed with schizophrenia or other psychotic disorders.

The purpose of this study is: * To investigate whether the response to antipsychotic treatment can be enhanced by adding cannabidiol (CBD) to the existing treatment, compared to placebo, in participants with a first episode of psychosis, who have had a suboptimal or no response to their first antipsychotic treatment. * To confirm the safety of CBD in people with psychosis. The study is a randomized, double-blind, placebo-controlled, multi-centre, clinical trial. Individuals with a diagnosis of first-episode psychosis, who have had a suboptimal or no response to their first antipsychotic treatment will be recruited. These participants are randomised to treatment with CBD oral solution 500mg twice daily, or a matching placebo for 6 weeks, as an adjunct to their existing antipsychotic treatment. By using a battery of clinical outcome assessments, the trial will also assess several biomarkers to determine if they can be used to predict clinical outcomes and response to treatment with CBD. Biomarkers are being assessed as an exploratory outcome measure. Participants will be invited to provide blood and stool samples, and may be asked to complete neuroimaging assessments at certain eligible sites.

The overall purpose of the proposed exploratory intervention development application, is to conduct research that will inform the adaptation and preliminary testing of NECT modified for youth (aged 15-24) with first episode psychosis (FEP), targeting self-concept and illness conceptions to increase treatment engagement. The specific aims of the project are to: 1) adapt NECT to be responsive to the needs and preferences of youth with FEP, and 2) Assess the feasibility, acceptability and preliminary effectiveness of the modified intervention (NECT-YA) combined with coordinated specialty care (CSC) services, compared to CSC services alone, in a small (n = 40) RCT.

The aims of this project is to use an artificial intelligence (AI) smartphone app to provide support for medication adherence by patients with first episode psychosis.

Maintaining treatment engagement is critical for first episode psychosis patients to experience gains possible with coordinated specialty care (CSC). This study is designed to identify CSC participants still receiving care but at high risk for disengagement and to intervene to prevent/delay disengagement.

The goal if the project is to develop a learning health network devoted to the treatment of first episode psychosis.
