Shining a light on brain energy: a new window into bipolar depression
NCT ID NCT07806227
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
Summary
Researchers are testing whether a light-based imaging technique called near-infrared spectroscopy can measure mitochondrial activity in the brain during bipolar depression. People with bipolar disorder who are depressed will undergo brain imaging before and after treatment with the approved medication lurasidone, and will also provide blood samples and answer questions about their history. Healthy volunteers without any psychiatric disorder will have the same imaging and questionnaires, but will not take the medication. The goal is to understand how mitochondrial function relates to depression symptoms and whether it changes with treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lurasidone (Latuda), an approved medication for bipolar depression, used to see how brain imaging signals change as symptoms improve.
- What this could lead to
- If this works, it could point toward a way to measure mitochondrial function in the brain, helping to guide depression treatment and deepen understanding of bipolar disorder.
- What could go wrong
- This is a small, early-stage imaging study, not a treatment trial. The results may not lead to a new therapy, and the imaging technique may not reliably reflect mitochondrial activity.
