Major Depressive Disorder (MDD) is a serious public health problem, due to its high prevalence and the severe disability that it can entail. In 30-40% of patients there is an incomplete response after two therapeutic attempts with an adequate dose and duration. In this group, considered to suffer from treatment-resistant MDD (TRMDD), the most effective therapeutic option is electroconvulsive therapy (ECT). There are no standardized and reproducible biomarkers to predict response to ECT in TRMDD.
We are carrying out a study aimed at characterizing structural connectivity as a predictor of response to ECT treatment. To this end, we are measuring diffusion-weighted magnetic resonance neuroimaging and clinical, including cognitive, evaluations, are being explored in a group of 26 patients with TRMDD in the Service of Psychiatry of Fleni Foundation.
