What this trial studies

This clinical trial investigates the effects of glucose and ketones on brain metabolism and behavior in individuals with bipolar disorder. Participants will undergo blood tests to assess metabolic function and two MRI scan sessions where they will engage in games that involve potential monetary rewards. The study aims to compare brain responses and energy usage between individuals with bipolar disorder and healthy controls, focusing on how these factors influence risk and reward processing. By understanding these metabolic pathways, the research seeks to shed light on potential dietary interventions for managing bipolar disorder.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 18-45 with a stable diagnosis of bipolar disorder who meet specific health criteria.

Not a fit: Patients with severe medical conditions, recent hospitalizations, or those who have undergone certain treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to dietary recommendations that improve brain function and behavior in patients with bipolar disorder.

How similar studies have performed: While the specific approach of using dietary components like glucose and ketones in bipolar disorder is novel, related studies have shown promise in understanding metabolic influences on mental health.
