Researchers at UC Davis Health, in a study published May 16, 2026, in Molecular Psychiatry, identified a consistent chemical pattern in the brains of individuals with anxiety disorders. A meta-analysis of 25 previous studies, encompassing 370 people with anxiety disorders and 342 control subjects, revealed approximately 8% lower levels of choline in the brains of those with anxiety.
This deficit was particularly pronounced in the prefrontal cortex, a region critical for emotional regulation and decision-making.
Choline is an essential nutrient vital for brain functions including memory, mood regulation, and nerve signaling. The body produces only small amounts, requiring most intake from dietary sources. This finding represents the first clear chemical brain pattern associated with anxiety disorders, suggesting a potential nutritional component to the condition.
The discovery indicates that nutritional interventions, such as choline supplementation, could offer new avenues for treatment by helping to restore brain chemistry. Anxiety disorders affect approximately 30% of adults in the United States, and many individuals do not receive adequate treatment. This research provides a foundation for exploring nutrition-based therapeutic strategies for these prevalent mental health conditions.
