Consensus of the Brazilian Headache Society (SBCe) for prophylactic treatment of episodic migraine: part II.

Background: Migraine affects 1 billion people worldwide and > 30 million Brazilians; besides, it is an underdiagnosed and undertreated disorder.

Objective: The need to disseminate knowledge about the prophylactic treatment of migraine is known, so the Brazilian Headache Society (SBCe, in the Portuguese acronym) appointed a committee of authors with the objective of establishing a consensus with recommendations on the prophylactic treatment of episodic migraine based on articles from the world literature as well as from personal experience.

Methods: Meetings were held entirely online, with the participation of 12 groups that reviewed and wrote about the pharmacological categories of drugs and, at the end, met to read and finish the document.

Consensus of the Brazilian Headache Society (SBCe) for the Prophylactic Treatment of Episodic Migraine: part I.

The Brazilian Headache Society (Sociedade Brasileira de Cefaleia, SBCe, in Portuguese) nominated a Committee of Authors with the aim of establishing a consensus with recommendations regarding prophylactic treatment for episodic migraine based on articles published in the worldwide literature, as well as personal experience. Migraine affects 1 billion people around the world and more than 30 million Brazilians. In addition, it is an underdiagnosed and undertreated disorder.

ID-Migraine™ questionnaire and accurate diagnosis of migraine.

Objective: To analyze the applicability of the Portuguese version of ID-MigraineTM in a sample of Brazilian patients.

Methods: Patients with headache were recruited from the neurology outpatient clinic of a tertiary hospital and submitted to the ID-MigraineTM questionnaire. The diagnosis of headache was made according to the ICHD-2 criteria.

Recommendations for the treatment of migraine attacks - a Brazilian consensus.

In this article, a group of experts in headache management of the Brazilian Headache Society developed through a consensus strategic measurements to treat a migraine attack in both the child and the adult. Particular emphasis was laid on the treatment of migraine in women, including at pregnancy, lactation and perimenstrual period.

The Behavior of Migraine in Patients with Parkinson's Disease.

Parkinson's disease (PD) is characterized by the degeneration of dopaminergic systems in the central nervous system. In migraine it is supposed to occur hyperactivation of central dopaminergic pathways. We verified the hypothesis of improved migraine in patients who manifest PD.

Botulinum Neurotoxin Type A in Neurology: Update.

This paper reviews the current and most neurological (central nervous system, CNS) uses of the botulinum neurotoxin type A. The effect of these toxins at neuromuscular junction lends themselves to neurological diseases of muscle overactivity, particularly abnormalities of muscle control. There are seven serotypes of the toxin, each with a specific activity at the molecular level.

Amyotrophic Lateral Sclerosis: New Perpectives and Update.

Amyotrophic lateral sclerosis (ALS), Charcot's disease or Lou Gehrig's disease, is a term used to cover the spetrum of syndromes caracterized by progressive degeneration of motor neurons, a paralytic disorder caused by motor neuron degeneration. Currently, there are approximately 25,000 patients with ALS in the USA, with an average age of onset of 55 years. The incidence and prevalence of ALS are 1-2 and 4-6 per 100,000 each year, respectively, with a lifetime ALS risk of 1/600 to 1/1000.

Another Perspective on Fasciculations: When is it not Caused by the Classic form of Amyotrophic Lateral Sclerosis or Progressive Spinal Atrophy?

Fasciculations are visible, fine and fast, sometimes vermicular contractions of fine muscle fibers that occur spontaneously and intermittently. The aim of this article is to discuss the main causes for fasciculations and their pathophysiology in different sites of the central/peripheral injury and in particular to disprove that the presence of this finding in the neurological examination is indicative of amyotrophic lateral sclerosis. Undoubtedly, most fasciculations have a distal origin in the motor nerve both in normal subjects and in patients with motor neuron disease.

Latin American consensus on guidelines for chronic migraine treatment.

Chronic migraine is a condition with significant prevalence all around the world and high socioeconomic impact, and its handling has been challenging neurologists. Developments for understanding its mechanisms and associated conditions, as well as that of new therapies, have been quick and important, a fact which has motivated the Latin American and Brazilian Headache Societies to prepare the present consensus. The treatment of chronic migraine should always be preceded by a careful diagnosis review; the detection of possible worsening factors and associated conditions; the stratification of seriousness/impossibility to treat; and monitoring establishment, with a pain diary.

Ankle-brachial index, a screening for peripheral obstructive arterial disease, and migraine - a controlled study.

Background: Epidemiological studies support the association between migraine, especially migraine with aura, and vascular disorders. The ankle-brachial index (ABI) is largely used as a surrogate of peripheral obstructive arterial disorders (POAD). Accordingly, in this study we contrasted the ABI in individuals with migraine and in controls.

A nationwide population-based study of tension-type headache in Brazil.

Objectives: To estimate the 1-year prevalence of tension-type headache (TTH) and the degree of the association of TTH with some sociodemographic characteristics of a representative sample of the adult population of Brazil.

Methods: This was an observational, cross-sectional, population-based study. We conducted telephone interviews on 3848 people, aged 18-79 years, randomly selected from the 27 states of Brazil.

Pulsatile tinnitus: treatment with clonazepam and propranolol.

Pulsatile tinnitus synchronous with heartbeat is rare and normally has vascular origin: arterial (malformation, arterial anatomical variation) or venous (aberrant jugular bulb, glomus tumors, tympanic glomus tumor). Early etiology identification is essential for appropriate treatment to be established. Magnetic angioresonance makes the vascular identification possible and precise.

Remission of refractory chronic cluster headache after warfarin administrations: case report.

Isolated reports of a possible positive effect of anti-coagulant drugs, among them heparin, warfarin and acenocumarol, in migraine prophylaxis are found in the literature. We report the case of a 37 years old man suffering from refractory chronic cluster headache that presented remission with the administration of warfarin for the treatment of deep venous thrombosis associated to arterial thrombosis. We did not found any case like that in the literature.

[Age as an independent risk factor for secondary headaches].

Objective: To verify if the age is a risk factor for secondary headaches, regardless the time interval since the onset of the headache complaint.

Method: 1131 patients were selected, with the main complaint of headache. The ratio of secondary headaches was evaluated and compared between young and elderly patients in general; between individuals with headache starting before and after 60 years of age; and between young and elderly subjects with headache having started for less than one year.
