What this trial studies

This study investigates the effects of ketamine on aesthetic perception and its potential role in alleviating symptoms of major depressive disorder. It involves 25 patients with major depressive disorder and 35 healthy controls, who will undergo two MRI assessments: one after receiving intravenous ketamine and another after a placebo. The study employs a single-center, placebo-controlled, cross-over design, utilizing various imaging techniques to evaluate aesthetic processing, reward, and sexual arousal, alongside neuropsychological assessments of depressive symptoms and anhedonia.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 18 to 55 with a diagnosis of major depressive disorder.

Not a fit: Patients with current or history of neurological diseases, significant medical illnesses, or those who have previously used ketamine may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into new therapeutic approaches for treating major depressive disorder through the lens of aesthetic perception.

How similar studies have performed: While the specific combination of aesthetic processing and ketamine's antidepressant effects is novel, previous studies have shown ketamine's efficacy in treating depression.
