Relationship Between Posttrauma GABA Plasma Levels and PTSD at 1-Year Follow-Up

Abstract

Gamma-aminobutyric acid (GABA) exerts a prominent effect on central adrenergic stress responses in times of high stress and has been associated with acute posttraumatic stress disorder (PTSD). The authors examined the association between low posttrauma plasma GABA levels and long-term PTSD.
