BioClock: Bright Light Therapy for Depressive Disorders

Bright Light Therapy (BLT) is a proven treatment for depression in seasonal and non-seasonal depressive disorders, as well as bipolar disorder. To make BLT more effective and practical in clinical settings and tailor it to individual needs, it is necessary to optimize the treatment approach, understand how the treatment works, and identify patient characteristics that predict response. This clinical trial has three main goals: * Optimize the administration of BLT for patients with depressive episodes. * Gain a deeper understanding of the treatment mechanisms. * Determine which patients benefit the most from the treatment. The specific objectives are as follows: * Investigate whether additional treatments and interventions related to lifestyle and the biological clock can enhance the effects of BLT. * Examine how BLT influences the body's internal clock and sleep quality, and how these factors contribute to the outcomes. * Identify patient characteristics and behaviours that can predict treatment outcomes. * Develop a brain model to better understand the impact of BLT on the brain. In this study, patients will receive BLT with a light intensity of 10,000 lux for 30 minutes each morning over 5 consecutive days. The treatment duration will range from one to three weeks, depending on the improvement of depressive symptoms. Participants will be randomly assigned to one of three groups: * Home - Patients will receive BLT at home, following the standard guidelines for light th…
