Conclusions.— Advanced magnetic resonance venographic techniques used in strictly selected subjects disclose transverse sinus asymmetries in as many as 50.6% of patients with chronic

migraine, even when mild differences in physiological caliber are excluded. The unexpected correlation between transverse sinus aplasia and some risk factors for migraine chronification requires confirmation in larger studies. ”
“Background.— Psychiatric comorbidities are common among patients with headache. These can compromise the quality of life of GSI-IX patients and may affect the result of treatment. No available systematic study concerning this problem has been conducted in Thailand. Objective.—

The study aimed to determine the prevalence and risk factors of psychiatric disorders in patients with headache in tertiary care facility. Methods.— The study was conducted at the Headache Clinic, King Chulalongkorn Memorial Hospital in Bangkok, Thailand. One hundred and thirteen patients were Selleck Metformin enrolled. Diagnosis of headache was made based on International Classification of Headache Disorders II system. Mental disorders were assessed using Primary Care Evaluation of Mental Disorders. Other possible risk factors were extracted using significant physical symptoms count and accumulated risk for mental disorder. Results.— Of the 113 samples analyzed, the prevalence of depression, anxiety, and somatoform disorder was found to be 29.2%, 9.7%, and 27.4%, respectively. No definite relationship between headache types and mental disorders was observed. High number of significant physical Immune system complaints and health concerns significantly increased the risk for depression (OR = 4.6, 95% CI = 1.6 to 13.5) while the level of possible risk for mental disorder was associated with an increased risk for somatoform disorder (OR = 1.6, 95% CI = 1.2 to 2.2). Conclusion.—

The study confirmed high prevalence of psychiatric comorbidities in patients with headache. The results of this study will raise the awareness of physicians to possible underlying mental disorders in patients with headache and facilitate appropriate treatment or psychiatric referral. ”
“(Headache 2011;51:693-706) Objective.— To estimate the prevalence of chronic migraine (CM) among adolescents and to describe the epidemiologic profile, headache characteristics, disability, and healthcare utilization of adolescents with CM in the USA. Background.— Chronic daily headache (CDH) and CM occur in children and adolescents, but are poorly understood in these populations because their presentation is different from that in adults. It may be difficult to assign a definitive diagnosis to young people suffering from CDH because symptoms may fail to meet the criteria for one of the CDH subtypes. Methods.
