What this trial studies

This clinical trial investigates the impact of a keto-like supplement on brain activity in response to emotional stimuli in individuals suffering from moderate to severe depression. It is a double-blind, randomized, placebo-controlled study involving 75 participants who will be assigned to receive either the supplement or a placebo for eight weeks. Participants will undergo various assessments, including fMRI scans and questionnaires, to evaluate changes in brain function and mood. The study aims to determine if the supplement can induce functional brain changes that correlate with emotional processing.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 with moderate to severe depression, as indicated by a PHQ-9 score of 10 or higher.

Not a fit: Patients with a history of significant suicidality or substance use disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel dietary intervention for improving emotional responses in patients with depression.

How similar studies have performed: While there is ongoing research into dietary supplements for mental health, this specific approach using a keto-like supplement is relatively novel and has not been extensively tested.
