Neuro-computational look at mood fluctuations in depression and bipolar disorder.

Neuro-computational Study of Thymic Fluctuations in Mood Disorders - MOODELING

Not applicable Interventional Centre Hospitalier St Anne · NCT07033923

What this trial studies

The project combines a single neuroimaging session (structural and optional functional MRI) with computerized cognitive tests and a year of daily smartphone-based mood monitoring using a mobile application. Investigators will recruit three groups of about 96 participants each: people with depressive disorder, people with bipolar disorder, and healthy controls. Computational models will be fit to the behavioral and neural data to characterize how mood fluctuates and how those fluctuations relate to brain activity in regions such as the ventromedial prefrontal cortex and anterior insula. The main goal is to determine whether these models can describe real-life mood dynamics and predict subsequent clinical evolution.

Who should consider this trial

Good fit: Ideal candidates are adults with a recent (within 12 months) diagnosed depressive episode or a bipolar mood episode who can undergo MRI and commit to daily smartphone monitoring for up to 12 months.

Not a fit: People who cannot complete daily mobile monitoring for 12 months, are under legal guardianship, or have contraindications to MRI are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the approach could produce personalized tools that help clinicians predict mood episodes and tailor monitoring or treatment plans.

How similar studies have performed: Previous neurocomputational work and fMRI studies in healthy volunteers have linked mood signals to vmPFC and anterior insula activity, but translating these findings into clinically useful prediction tools remains largely unproven.
