Abstract:
|
There is growing evidence that individual differences among depression patients on Electrophysiology (EEG), fMRI and other brain imaging measurements may be predictive of potential treatment response. In this talk we discuss approaches to identifying potential placebo responders, i.e., a subgroup who benefits sufficiently from inactive drug treatments, using EEG measurements as a functional predictor. We propose to formulate this task as a statistical learning problem with support vector machine (SVM) classifier. Our approach will be evaluated through simulations and will be applied to data from a large clinical trial for patients with major depressive disorders.
