Catechol-O-Methyltransferase (COMT) rs4680Val158Met Polymorphism is Associated With Widespread Pressure Pain Sensitivity and Depression in Women With Chronic, but not Episodic, Tension-Type Headache

Objectives: The aims of this study were: (1) to investigate the association between the rs4680Val158Met polymorphism in frequent episodic tension-type headache (FETTH) and chronic tension-type headache (CTTH); and (2) to analyze the association between the rs4680Val158Met polymorphism with clinical, psychological, or psychophysical variables. Methods: In total, 50 women with FETTH, 50 with CTTH, and 50 matched headache-free women participated. After amplifying Val158Met polymorphism by polymerase chain reaction, the genotype frequencies and allele distributions based on restriction fragment length polymorphism were assessed. Participants were classified according to the Val158Met polymorphismrs4680 genotype (Val/Val, Val/Met, or Met/Met). A headache diary collected clinical features. Disability (Headache Disability Inventory), sleep quality (Pittsburgh Sleep Quality Index), and depression/anxiety levels (Hospital Anxiety and Depression Scale) were also assessed. Pressure pain thresholds were assessed bilaterally over the temporalis, upper trapezius, second metacarpal, and tibialis anterior by a blinded assessor. Results: The distribution of rs4680 Val158Met genotype was not significantly different between women with/without headache (P=0.796). No differences in headache features, disability, anxiety, or sleep quality were observed depending on the rs4680 Val158Met genotype. Women with CTTH, but not FETTH, carrying the Met/Met genotype had lower widespread pressure pai...

Conclusion: The results of our study may suggest the presence of FM as a clinical sign of a more severe migraine. However, the long-term prospective studies including these group of patients are needed to understand the prognostic impact and importance of the comorbid FM in migraine.

Conclusion: These findings support the hypothesis that in FM a deteriorated function of cortical inhibition, indexed by a higher SICI parameter, a lower function of the DPMS, together with a higher level of BDNF indicate that FM has different pathological substrates from depression. They suggest that an up-regulation phenomenon of intracortical inhibitory networks associated with a disruption of the DPMS function occurs in FM. Introduction Major depressive disorder (MDD) and fibromyalgia (FM) present overlapped symptoms. Although the connection between these two disorders has not been elucidated yet, the disruption...

Fibromyalgia (FM) is a chronic pain disorder of uncertain etiology characterized by widespread pain and numerous potential comorbidities including fatigue, disordered sleep, neurocognitive deficits, gastrointestinal distress, headache, anxiety, and depression.61 This symptomatology often presents in an unpredictable remitting/relapsing cycle that further detracts from patients' quality of life and results in significantly increased medical costs, health care utilization, and work-related disability.

CONCLUSION Cognitive impairment can affect daily functioning, quality of life, and capacity to work in patients with cancer and those in remission. Consequently, cognitive assessment is now an important and necessary part of a comprehensive oncological care plan. Cancer-related cognitive impairment might be due to the direct effects of the cancer itself, nonspecific factors, or comorbid conditions that are independent of the disease and/or due to the adverse effects of the treatment or combination of treatments given for the disease. The prevalence and extent of cognitive impairment associated with cancer is recognized but...

AbstractBackgroundTo investigate variables associated at one year (longitudinal design) with the physical or emotional component of burden in chronic tension type headache (CTTH).MethodsOne hundred and thirty (n = 130) individuals with CTTH participated in this longitudinal study. Clinical features were collected with a 4-weeks headache diary at baseline and 1-year follow-up. The burden of headache was assessed at baseline and one -year follow-up with the Headache Disability Inventory (HDI), physical ( HDI-P) or emotional (HDI-E) component. Sleep quality (Pittsburgh Sleep Quality Index), anxiety and depressio...

ConclusionsThe HEAD program, created to help manage lengthy appointment wait times, was associated with lowering migraine‐associated disability, decreasing ED visits, reducing medication and narcotic use and overuse. Education empowers patients to take an active role in their care, especially in regards to improving treatment timing and modifiable lifestyle behaviors. This education program can potentially play a role in early intervention for headache patients especially with chronic migraine and medication overuse headache.

Abstract OBJECTIVE: To examine whether sleep disturbance differs by headache diagnosis in a pediatric sample, and whether this effect remains when other factors affecting sleep are included. BACKGROUND: Primary headache disorders can be severe and disabling, impacting a child's functioning and quality of life. Many children and adolescents with chronic headaches also experience sleep difficulties, and there is likely a bidirectional relationship between headaches and sleep difficulties. Sleep problems may intensify functional and developmental difficulties in youth with chronic headaches. Despite this, resear...

Conclusion This study describes what makes the subgroup of pain patients most affected by their pain special according to associated factors and comorbidity We found that they were distinguished by a high degree of psychiatric comorbidity, low physical functioning and extreme levels of symptom preoccupation/hypervigilance. Many severe symptoms additional to pain (e.g. depression/anxiety, tiredness, disturbed sleep, lack of concentration, constipation) were reported. The group seems hypervigilant, overwhelmed with a multitude of different symptoms on a high severity level. Implications When treating this complex group, the ...

ConclusionsThis study outlined a relevant presence of symptoms of central sensitization among children with migraine. Severe allodynia and comorbidity for JFM seemed to cause a general decline of quality of life, which would suggest the opportunity of a routine assessment of these clinical features.
