Low brain choline linked to anxiety disorders.

Study finds 8% lower choline in brains of people with anxiety disorders.

Why it matters

  • Anxiety disorders are highly prevalent and often untreated.
  • Identifying neurometabolic abnormalities could lead to new treatments.

By the numbers

  • 370 patients and 342 controls were studied.
  • 8% lower choline levels in anxiety disorder patients.
  • Effect size (Hedges’ g) of -0.64 for cortical tCho.

The big picture

  • Reduced choline levels are consistent across different anxiety disorders.
  • This suggests a potential metabolic mechanism for anxiety disorders.

What they're saying

  • Some suggest a "Goldilocks zone" for choline levels, as supplements might cause anxiety/depression.
  • Interest in dietary sources of choline (like eggs) and related nutrients (like magnesium).

Caveats

  • The study is a meta-analysis based on existing data.
  • More research is needed to confirm if choline supplementation could be a treatment.

What’s next

  • Future studies may explore the clinical significance of these findings.
  • Potential for choline supplementation as a therapeutic option could be investigated.
