BACKGROUND: Patients with medication-overuse headache suffer not only from chronic headache, but often from psychiatric comorbidities, such as anxiety and depression. The mechanisms underlying these comorbidities are unclear, but the amygdala is likely to be involved in their pathogenesis. To investigate the mechanisms underlying the comorbidities we used elevated plus maze and open field tests to assess anxiety-like behavior in rats chronically treated with analgesics. We measured the electrical properties of neurons in the amygdala, and examined the cortical spreading depression (CSD)-evoked expression of Fos in the trigeminal nucleus caudalis (TNC) and amygdala of rats chronically treated with analgesics...

OBJECTIVE: Using surface-based morphometry we aimed to provide a detailed examination of cortical alterations in medication-overuse headache (MOH), by disentangling between altered cortical thickness and gyrification (folding). BACKGROUND: In MOH, pain modulation is probably dysfunctional at the cortical and subcortical level, resulting in a disequilibrium between pain inhibition and facilitation. Both increased and decreased cortical volumes have been reported in individuals with MOH...

Worldwide, about 1-2% of the adult population suffers from chronic headache due to overuse of pain medication. Guidelines recommend acute withdrawal of medication, but the optimal treatment remains unknown. We aim to evaluate the benefit of treatments for patients with medication overuse headache (MOH). We performed an extensive literature search until November 2015, selecting randomized controlled trials that evaluated interventions for adults with MOH. Two authors assessed the eligible trials and extracted data...

Headache is very common in children and young people. The correct advice and treatment requires consideration of a wide differential diagnosis between primary and secondary headaches, and also of the different types of primary headache. The International Classification of Headache Disorders gives useful descriptions and diagnostic criteria that are especially useful for primary headaches. The National Institute for Health and Care Excellence (NICE) Clinical Guideline 150 provides evidence-based recommendations on treatments for adults and young people from age 12 years...

BACKGROUND: OnabotulinumtoxinA (OnabotA) is effective in Chronic Migraine (CM) during first year of treatment and longer. In real clinical setting, CM patients with acute Medication Overuse (MO) or concurrently receiving oral preventatives are treated with OnabotA. We aim to assess evolution of CM patients beyond first year on OnabotA. METHODS: Data were retrospectively collected in three headache units. We analyzed cases who had received at least five sessions of OnabotA according to PREEMPT protocol...

BACKGROUND: Knowledge of the epidemiology of primary headache disorders in sub-Saharan Africa (SSA) remains very limited. We performed a population-based survey in rural and urban areas of Ethiopia, using methods similar to those of an earlier study in Zambia and tested in multiple other countries by Lifting The Burden. METHODS: In a cross-sectional survey we visited households unannounced in four regions of Ethiopia: the mostly urban populations in Addis Ababa and its environs and rural populations of selected districts in Oromia, Amhara and South Nations Nationalities and People's Regions States (SNNPRS)...

BACKGROUND: In evidence-based guidelines published in 2000, topiramate was a third-tier migraine preventive with no scientific evidence of efficacy; recommendation for its use reflected consensus opinion and clinical experience. Its neurostabilizing activity, coupled with its favorable weight profile, made topiramate an attractive alternative to other migraine preventives that caused weight gain. When guidelines for migraine prevention in episodic migraine were published in 2012, topiramate was included as a first-line option based on double-blind, randomized controlled trials involving nearly 3000 patients...

BACKGROUND: The most commonly prescribed medications used to treat migraine acutely are single analgesics, ergots, opioids, and triptans. Due to varying mechanisms of action across drug classes, there is reason to believe that some classes may be less likely than others to elicit Medication Overuse Headache (MOH) than others. We therefore aimed to determine whether certain classes of acute migraine drugs are more likely to elicit MOH than others. METHODS: A comprehensive systematic literature was conducted to identify studies of varying designs that reported on MOH within the considered treatment classes...

AIM: Medication-overuse headache (MOH) is a challenging clinical disorder often resulting in frustration for patients and physicians. Adherence issues are common and limited treatment evidence is an obstacle to effective care. Individual bias usually directs the treatment. The aim of this study was to evaluate outcome and treatment strategies in consecutive MOH patients from a tertiary center. METHODS: Every consecutive patient seen between January and December 2014 with the diagnosis of MOH was included...

BACKGROUND: Studies addressing relapse rates conflate relapse into chronic migraine (CM) and medication overuse (MO), and the consequent need to repeat withdrawal. We aim to identify 12-months predictors of relapse into CM (based on headaches frequency) separately from occurrence of another structured withdrawal. METHODS: Hospitalized patients with CM-MO under withdrawal were enrolled. Candidate predictors included demographic, disability, quality of life, depression scores, general self-efficacy, social support, headaches frequency and intensity, class of overused medications, history of withdrawal treatment in the three years prior to enrollment, attendance to emergency room (ER) between enrollment and follow-up, nonattendance to outpatient neurological examinations...

BACKGROUND AND PURPOSE: New-onset headache in elderly patients is generally suggestive of a high probability of secondary headache, and the subtypes of primary headache diagnoses are still unclear in the elderly. This study investigated the characteristics of headache with an older age at onset (≥65 years) and compared the characteristics between younger and older age groups. METHODS: We prospectively collected demographic and clinical data of 1,627 patients who first visited 11 tertiary hospitals in Korea due to headache between August 2014 and February 2015...

BACKGROUND: Pain freedom at 2 hours and sustained pain response at 24 hours are important outcomes of acute migraine therapy. Some studies have examined rates and predictors of successful treatment outcomes for single attacks in clinical trials. However, little is known about predictors of typical response to acute treatment over multiple attacks in the population. OBJECTIVES: To identify sociodemographic features, headache characteristics, comorbidities and treatment-related factors that predict acute treatment success or failure at 2 hours and 24 hours post dose in a US population sample of persons with episodic migraine...

Medication-overuse headache (MOH) is a disabling, costly and often overlooked disorder. The prevalence in Denmark is 1.8% equivalent to 80.000-100.000 adults. The aim is to increase awareness of clinical presentation and treatment options for patients with MOH when encountered in primary care setting, exemplified by three representative cases. Clinical presentation of MOH and three treatment approaches are discussed. MOH is a chronic disorder which is preventable and treatable.

Many headache patients self-medicate and choose their preferred analgesic from a range of acute analgesics available on the high-street and from community pharmacies. Little is known about their presenting symptoms, headache diagnosis and their preferred treatments. A questionnaire was distributed to community pharmacies in the Munster region of Ireland and was administered to patients requesting treatment for headache. A total of 1023 completed questionnaires were received, 76.7% (n=765) were female and 51...
