Brain scans and blood tests could reveal who benefits from lithium
NCT ID NCT06396312
First seen Oct 09, 2026 · Last updated Oct 09, 2026
Summary
Researchers at the Max Planck Institute of Psychiatry are studying whether combining brain imaging, EEG, blood tests, and cognitive assessments can predict which people with treatment-resistant depression respond to lithium. The study enrolls 130 adults with major depressive disorder who have not improved after at least one antidepressant and for whom lithium augmentation is clinically indicated. Participants undergo detailed clinical and biological testing, and researchers use machine learning to look for a pattern that might forecast response. The study does not assign treatment; patients and their doctors decide on lithium as part of routine care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If the signature works, doctors could one day estimate who is likely to benefit from lithium before starting it, sparing others from a treatment that may not help.
- What could go wrong
- This is an observational study, not a test of whether lithium works. The signature may fail to predict response accurately, and it may not apply to patients outside this group.
