"Pathophysiology: Although the etiology remains unclear, characteristic alterations in the pattern of sleep and changes in neuroendocrine transmitters such as serotonin, substance P, growth hormone and cortisol suggest that regulation of the autonomic and neuro-endocrine system appears to be the basis of the syndrome. Fibromyalgia is not a life-threatening, deforming, or progressive disease. Anxiety and depression are the most common association. Aberrant pain processing, which can result in chronic pain, may be the result of several interplaying mechanisms. Central sensitization, blunting of inhibitory pain pathways and alterations in neurotransmitters lead to aberrant neuro-chemical processing of sensory signals in the CNS, thus lowering the threshold of pain and amplification of normal sensory signals causing constant pain.""The frequent co-morbidity of fibromyalgia with mood disorders suggests a major role for the stress response and for neuroendocrine abnormalities. The hypothalamic pituitary axis (HPA) is a critical component of the stress-adaptation response. In FMS, stress adaptation response is disturbed leading to stress induce symptoms. Psychiatric co-morbidity has been associated with FMS and needs to be identified during the consultation process, as this requires special consideration during treatment."

 * 2015, Evidence for brain glial activation in chronic pain patients

"Whole-brain voxel-wise analyses. (A) Median SUVR map from healthy controls (n = 9) and patients with chronic LBP (n = 10) are presented. Matched-pairs tests (nine versus nine) revealed significantly higher TSPO levels in patients, in thalamus, pre- and postcentral gyri, and paracentral lobule (P < 0.05 corrected for multiple comparisons; permutation testing, 10 000 permutations). As two patients were matching the same controls, the analyses were performed first using the patient best matching the control. A second analysis was performed using the other patient, limiting our search to significant clusters from the first analysis, with identical results. (B) Boxplots for each of the four regions demonstrating statistically higher SUVRs in patients are shown for illustrative purposes. postc. = postcentral; g. = gyrus; parac. lob. = postcentral lobule; prec. = precentral."

"Nearly 500 FM, autoimmune and healthy control patients underwent testing for cytokine/chemokine activity after mitogenic stimulation. Using a numerical score, all three groups had unique patterns with FM patients demonstrating less response to stimulation. This cytokine profile test had a 93 % sensitivity and an 89.4 % specificity for the diagnosis of FM. We also found that these profiles are relatively sensitive and specific for FM compared to SLE and RA. It remains unclear if these differences are directly related to the pathogenesis of FM."

"There does not appear to be firm and consistent evidence to support the hypothesis that the prevalence of BPD (Borderline Personality Disorder) would be higher in individuals with fibromyalgia compared with the general population."

Fibromyalgia causes subclinical axonal damage in the RNFL that can be detected using innocuous and non-invasive OCT, even in the early disease stages. The impact on the RNFL in the temporal sectors is greater in patients with biologic fibromyalgia, suggesting the presence of neurodegenerative processes in this subgroup of patients with fibromyalgia.

"Here, we identify a set of three brain patterns based on fMRI responses to pressure pain and non-painful multisensory stimulation. These patterns, taken together, discriminate FM from matched healthy controls with 92% sensitivity and 94% specificity."

"Figure 2. Multivariate brain pattern that predicts fibromyalgia status on the basis of brain activation during painful (pressure) stimulation. Positive weight values reflect higher pain-evoked activation in FM patients relative to healthy participants, whereas negative weight values reflect reduced pain-evoked activation in FM patients. A. SVM pattern of whole-brain voxel weights that optimizes classification of FM patients and healthy participants. We provide the voxel-by-voxel weights for three representative regions (anterior SII, right dorsolateral and dorsomedial PFC) to illustrate the concept of weighted pattern. B. Regions whose voxel weights contributed most reliably to the prediction of FM status (q<0.05 FDR-corrected for the first two rows; p-uncorrected<0.001 to further illustrate the findings)."

 * 2018, SNPs in inflammatory genes CCL11, CCL4 and MEFV in a fibromyalgia family study

"SNPs with significant TDTs were found in 36% of the cohort for CCL11 and 12% for MEFV, along with a protein variant in CCL4 (41%) that affects CCR5 down-regulation, supporting an immune involvement for FM."

"What we did not find in our unbiased CritFM samples was 9:1 female to male fibromyalgia ratios that are widely described by expert sources [11–13]. We believe that such findings only occur in the presence of selection bias or biased ascertainment.""As unbiased epidemiological studies show only a small increase in the female to male sex ratio (~1.5:1) as opposed to the observed ratio in clinical studies of 9:1, we believe that the over-identification of fibromyalgia in women and the consequent under-identification of men is the result of bias." "FM is a disease continuum characterized by progressive and identifiable classifications. Four classes of FM can be differentiated by pain and symptom severity, specific comorbidities, and use of clinical procedures." "This commentary presents a simplified way of making the diagnosis of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) using the 1994 Centers for Disease Control and Prevention case definition. The format used can easily be modified for other case definitions. The commentary then discusses whether ME/CFS is the same or a different illness from fibromyalgia. Because overlap exists between the 2 syndromes, some investigators have posited that they are variants of the same illness. I have viewed this as an empirically testable hypothesis and have summoned considerable amounts of data that suggest that the 2 illnesses differ. Were differences to exist, that would suggest different pathophysiologic processes for each, leading to different treatments."

Psychological paradigm

 * 2012, Personality and Fibromyalgia Syndrome

"Conclusion: No specific fibromyalgia personality is defined but it is proposed that personality is an important filter that modulates a person’s response to psychological stressors. Certain personalities may facilitate translation of these stressors to physiological responses driving the fibromyalgia mechanism."
