“Spontaneous intracranial hypotension (SIH) is typically characterized by orthostatic headache; however, various atypical manifestations of SIH have been
reported recently. We report here the case of a 46-year-old man with headache secondary to SIH, which was nonorthostatic, triggered only when the patient shook his head. We suggest that SIH should be suspected in patients with headache induced by head-shaking, even without orthostatic features, especially when the headache is accompanied by other symptoms commonly associated with SIH. “
“Background.— Studies using resources of a public family health program to estimate the prevalence of chronic STAT inhibitor daily headaches (CDH) are lacking. Objectives.— To estimate the 1-year prevalence of CDH, as well as the presence of associated psychiatric and temporomandibular disorders (TMD) comorbidities,
on the entire population of a city representative of the rural area of Brazil. Methods.— This was a cross-sectional, population-based, 2-phase study. In the first phase, health agents interviewed all individuals older than 10 years, in a rural area of Brazil. In the second stage, all individuals who reported headaches on 4 or more days per week were then evaluated by a multidisciplinary team. CDH were classified according to the second edition of the International Classification of Headache Disorders (ICHD-2). Medication overuse headache selleck chemicals llc was diagnosed, as per the ICHD-2, after detoxification trials. Psychiatric comorbidities JAK inhibitor review and TMD were diagnosed based on the DSM-IV and on the Research Diagnostic Criteria for Temporomandibular Disorders criteria, respectively. Results.— A total of 1631 subjects participated in the direct interviews. Of them, 57 (3.6%) had CDH. Chronic migraine was the most common of the CDH (21, 36.8%). Chronic tension-type headache (10, 17.5%), medication overuse headache (13, 22.8%) and probable medication overuse headache
(10, 17.5%) were also common. Psychiatric disorders were observed in 38 (67.3%) of the CDH subjects. TMD were seen in 33 (58.1)% of them. Conclusions.— The prevalence of CDH in the rural area of Brazil is similar to what has been reported in previous studies. A significant proportion of them have psychiatric comorbidities and/or TMD. In this sample, comorbidities were as frequent as reported in convenience samples from tertiary headache centers. (Headache 2010;50:1306-1312) “
“The primary aim of our study was to evaluate if a group of medication-overuse headache (MOH) patients present dysfunctions in the mesocorticolimbic dopamine circuit. The secondary aim was to disentangle the role of the medication overuse and of the acute/chronic headache in determining these alterations and to investigate their persistence. Several researches have suggested that MOH may belong to the spectrum of addictive behavior.
