- UC Davis Health published its meta‑analysis in Molecular Psychiatry, covering 25 brain‑imaging studies of 370 anxiety patients and 342 controls.
- Choline concentrations were on average 8% lower in the brains of anxiety patients compared with controls.
- Prefrontal cortex showed the strongest choline deficit, a region tied to emotional regulation and decision‑making.
- Jason Smucny co‑author said the chemical pattern suggests nutritional approaches may help restore brain chemistry.
- Richard Maddock senior author suggested choline supplementation may restore brain chemistry and improve outcomes.
Why it matters: Anxiety disorders are among the most common mental health conditions in the U.S.; the identified choline deficit offers a concrete biomarker that clinicians can assess, opening a path toward nutrition‑focused interventions.
