RESUMO

Migraine is a severe and common primary headache disorder, characterized by pain as well as a plethora of non-painful symptoms. Among these, visual phenomena have long been known to be associated with migraine, to the point where they can constitute a hallmark of the disease itself. In this review we focus on two key visual disorders that are directly or indirectly connected to migraine: visual aura and visual snow syndrome (VSS). Visual aura is characterized by the transient presence of positive and negative visual symptoms, before, during or outside of a migraine attack. VSS is a novel stand-alone phenomenon which has been shown to be comorbid with migraine. We discuss key clinical features of the two disorders, including pathophysiological mechanisms, their differential diagnoses and best treatment practices. Our aim is to provide an aid for clinicians and researchers in recognizing these common visual phenomena, which can even appear simultaneously in patients with an underlying migraine biology.

RESUMO

INTRODUCCIÓN: La migraña es una cefalea primaria frecuente y debilitante. La catastrofización ante el dolor (CAD) es un constructo mental negativo exagerado que se manifiesta durante la experiencia dolorosa real o en forma anticipada a ella. El miedo anticipatorio ante el dolor, una de sus características, se ha asociado con una mayor prescripción y utilización de analgésicos. OBJETIVO: Explorar la CAD en relación con el abuso de analgésicos y el impacto de la migraña en la calidad de vida en pacientes con migraña crónica. PACIENTES Y MÉTODOS: Se realizó un estudio analítico transversal observacional. Se incluyó a pacientes mayores de 18 años con migraña crónica, a los cuales se les administró de forma anónima la Pain Catastrophizing Scale y el Head Impact Test-6. RESULTADOS: Al comparar la incidencia de abuso de analgésicos entre pacientes con niveles clínicos de CAD y pacientes sin CAD, la probabilidad de presentar abuso de analgésicos fue 16 veces mayor en el primer grupo (odds ratio = 16,06; IC 95% = 5,91-43,61; p < 0,0001). Al comparar la presencia de un gran impacto de la migraña en pacientes con CAD y sin CAD, la probabilidad de un gran impacto de la migraña es aproximadamente ocho veces mayor en el primer grupo (odds ratio = 8,27; IC 95% = 3,19-21,42; p < 0,0001). CONCLUSIÓN: Niveles clínicos de CAD en pacientes con migraña crónica se asociarían a una mayor incidencia de abuso de analgésicos y un mayor impacto de la cefalea en la calidad de vida


INTRODUCTION: Migraine is a frequent and debilitating primary headache. Pain catastrophizing is a negative set activated in response to anticipated or actual pain. The anticipatory fear of pain, one of its characteristics, has been associated with a greater prescription and use of analgesics. AIM: To explore the pain catastrophizing in relation to analgesic overuse and the headache impact on quality of life in patients with chronic migraine. PATIENTS AND METHODS: An observational cross-sectional analytical study was performed. Patients older than 18 years with chronic migraine were included, who were given anonymously the Pain Catastrophizing Scale and the Head Impact Test-6. RESULTS: When comparing the incidence of analgesic overuse among patients with clinical pain catastrophizing levels and those without pain catastrophizing, the probability of analgesic overuse was 16 times higher in the first group (odds ratio = 16.06; 95% CI = 5.91-43.61; p < 0.0001). When comparing the presence of a severe migraine impact in patients with and without pain catastrophizing, the probability of a severe migraine impact is approximately eight times greater in the first group (odds ratio = 8.27; 95% CI = 3.19-21.42; p < 0.0001). CONCLUSION: Clinical levels of pain catastrophizing in patients with chronic migraine might be associated with a higher incidence of analgesic overuse and a greater headache impact on quality of life

RESUMO

Resumen Introducción: El síndrome de vasoconstricción cerebral reversible es una entidad clínica y radiológica caracterizada por cefalea en estallido recurrente y vasoconstricción segmental multifocal de las arterias cerebrales, acompañado o no de otros déficits neurológicos, el cual resuelve espontáneamente en uno a tres meses. Métodos: Se reporta el caso clínico de una paciente que fue diagnosticada de síndrome de vasoconstricción cerebral reversible secundario a fármacos vasoactivos. Se plantea una búsqueda bibliográfica y una puesta al día de las últimas actualizaciones en relación a esta patología. Conclusión: Al menos la mitad de los casos de este síndrome son secundarios, sobre todo postparto y/o por la exposición a sustancias vasoactivas tales como drogas ilícitas, simpaticomiméticos y serotoninérgicos. Es trascendental identificar este cuadro a fin de retirar los posibles agentes causales, o evitar las complicaciones potenciales


Introduction: Reversible cerebral vasoconstriction syndrome is a clinical-radiologic syndrome characterized by recurrent thunderclap headache, with or without other acute neurological symptoms, and diffuse segmental constriction of cerebral arteries that resolves spontaneously within 3 months. Methods: It is described a clinic case of a woman, who was diagnosed with reversible cerebral vasoconstriction syndrome. A literature search and an update of the latest updates regarding this disease was done. Conclusion: At least half of the cases of this syndrome are secondary, especially postpartum and/or exposure to vasoactive substances such as illicit drugs, sympathomimetics and serotonergic drugs. It is crucial to identify this disorder in order to remove possible causative agents, or avoid potential complications.
