Filter by:The purpose of this study is to investigate the responses of the brain region known as the subgenual anterior cingulate cortex (sgACC) during transcranial magnetic stimulation (TMS) in individuals with depression. Specifically, investigators aim to determine whether the sgACC is engaged when TMS is delivered to specific targets and if the engagement of sgACC changes throughout a full TMS treatment intervention. To achieve this goal, the investigators will employ a combination of TMS and Magnetic Resonance Imaging (MRI) procedures. Study participation will include completing various questionnaires, clinical assessments, receiving a full transcranial magnetic stimulation (TMS) treatment intervention (every weekday for 4-6 weeks), and undergoing MRI scans, both with and without concurrent TMS.
Depressive disorders are among the most common psychiatric disorders. However, this disorder is multifaceted, as are its etiological factors, and is not yet fully understood. Within the framework of the P4D study, 1000 patients with depression will be comprehensively examined. In addition to the recording of psychological factors by means of questionnaires and third-party assessments, imaging and electrophysiological procedures (functional and structural MRI, EEG) are used to assess brain structure and function. In addition, blood is drawn from the subjects to analyze these samples for various biological markers (e.g., genetics). Drug level measurements are also performed. The goal is to perform an in-depth characterization (phenotyping) of individuals with a depressive disorder. These findings could be used to individualize and improve therapy for depressive disorders.
This study aims to better adapt cognitive behavioral therapy for insomnia (CBTi) for people with comorbid depression by using objective sleep measures to tailor the behavioral interventions components of CBTi. Using ambulatory monitors, we also aim to investigate changes in brain activity and heart rate throughout the intervention. In this parallel-group randomized clinical trial, participants undergo one week of baseline ambulatory monitoring after which they are randomly assigned to one of two intervention arms: 1) digitally delivered CBTi (eCBTi) based on standard subjective sleep measures (sleep diary), or 2) eCBTi based on objective sleep measures (EEG headband). The intervention spans over 5-weeks, followed by a week of ambulatory monitoring and follow-up measures one week and one month after the end of the intervention. The study also includes a post-intervention interview to gather feedback on participant experiences. The overall protocol includes online questionnaires and structured clinical interviews assessing sleep, insomnia, and mental health, as well as treatment-related measures before, during, and after the intervention. It is anticipated that eCBTi using objective sleep measures will lead to better treatment acceptability, satisfaction, and effectiveness, including greater improvements in symptoms of insomnia and depression. It is also anticipated that sleep EEG and heart rate profiles will improve along the course of eCBTi.
