Brain implants and wearables to monitor and help severe bipolar depression

Building Mood State Classifiers to Inform Deep Brain Stimulation (DBS) of Treatment-Resistant Bipolar Depression

['FUNDING_OTHER'] · BAYLOR COLLEGE OF MEDICINE · NIH-11178411

This project uses an implanted brain stimulator together with phone and wearable data to detect mood patterns and help people whose bipolar depression hasn't responded to other treatments.

What this research studies

If you join, you'll receive a sensing-capable deep brain stimulation device placed in a mood-related brain area (ventral capsule/ventral striatum). The device's brain signals will be time-locked with data from a smartphone app and wearables like an Apple Watch to capture sleep, activity, and behavior. Researchers will use those data to build computerized mood classifiers that identify depression, mania, and mixed states and track transitions over time. Much of the monitoring happens remotely, with regular clinic visits for surgery and follow-up.

Who could benefit from this research

Good fit: Adults with bipolar disorder whose depression has not improved after multiple standard treatments and who are willing and medically able to undergo DBS surgery and device monitoring.

Not a fit: People with milder bipolar symptoms, those who are not surgical candidates, unwilling to use a smartphone or wearable, or with major medical contraindications may not benefit.

Why it matters

Potential benefit: Could enable more precise, timely brain stimulation and personalized care that reduces severe, treatment-resistant depressive episodes.

How similar studies have performed: Deep brain stimulation has helped some people with severe mood disorders in prior studies but results are mixed, and combining chronic brain sensing with wearables is a newer approach with limited early promising evidence.
