The BAARD Study : Evaluating a Computerized Approach to Treatment Selection in Older Adults With Treatment Resistant Depression.

The goal of this clinical trial is to test whether a personalized approach to treatment selection improves symptoms in older adults with treatment-resistant depression. The main questions it aims to answer is: Will using the BAARD predictive models to select medications lead to better depression outcomes, compared to randomly selecting medications? Researchers will use the BAARD predictive models or random assignment to choose one of two medications to add to patients' current treatment. Patients will be asked to take either aripiprazole or bupropion along with their current medication. Participants will: Take Aripiprazole or Bupropion in addition to their current medication for 10 weeks. Complete follow-up assessments every 1-2 weeks for checkups.
