Comparison of the Efficacy of Transcranial Direct Current Stimulation at Home Versus in Hospital Settings in Patients With Depressive Episodes

Transcranial direct current stimulation (tDCS) is a neuromodulation method that modulates brain activity using low-intensity electrical current. Used in the treatment of depression, it is easily adaptable for both caregivers and patients, with good tolerance, under appropriate supervision. Allowing patients to perform tDCS at home could address issues of access to care (distance from home, overall cost of care, lack of healthcare professionals, difficulty travelling for physical/psychological reasons, etc.). Studies on tDCS have highlighted the importance of regular clinical monitoring to ensure compliance and safety, which are essential factors for therapeutic efficacy. The main objective of this study is to demonstrate the non-inferiority of tDCS performed at home versus in hospital in terms of effectiveness in reducing depressive symptoms at 6 weeks post-treatment in patients with moderate to severe depression.
