Plasma neuropeptide Y: A biomarker for symptom severity in chronic fatigue syndrome

Chronic fatigue syndrome (CFS) is a complex, multi-symptom illness with a multisystem pathogenesis involving alterations in the nervous, endocrine and immune systems.

Abnormalities in stress responses have been identified as potential triggers or mediators of CFS symptoms.

This study focused on the stress mediator neuropeptide Y (NPY). We hypothesized that NPY would be a useful biomarker for CFS.
