Condition: First Episode Psychosis · Sponsor: Université de Sherbrooke
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 …
