The levels of Cr and phosphocreatine (PCr) relative to total Cr (tCr), which includes Cr and PCr, in the ACC, thalamus, and insula were determined using MRS in 12 patients with FM and in 13 healthy controls. The FM group had lower levels of PCr\/tCr in the ACC and right insula compared to healthy controls. There was a negative correlation between Cr\/tCr in the ACC and total pain levels (McGill Pain Questionnaire-Total; r\u2009=\u2009\u22120.579, p\u2009=\u20090.049) and between Cr\/tCr in the left insula and affective pain levels (McGill Pain Questionnaire-Affective; r\u2009=\u2009\u22120.638, p\u2009=\u20090.047) in patients with FM. In addition, there were negative correlations between stress levels (Stress Response Inventory) and Cr\/tCr in the right (r\u2009=\u2009\u22120.780, p\u2009=\u20090.005) and left thalamus (r\u2009=\u2009\u22120.740, p\u2009=\u20090.006), as well as in the right insula (r\u2009=\u2009\u22120.631, p\u2009=\u20090.028) in patients with FM. There were negative correlations between symptom levels of post-traumatic stress disorder (PTSD; PTSD checklist) and Cr\/tCr in the right (r\u2009=\u2009\u22120.783, p\u2009=\u20090.004) and left thalamus (r\u2009=\u2009\u22120.642, p\u2009=\u20090.024) of patients with FM. These findings are paramount to understanding the decisive pathologies related to brain energy metabolism in patients with
