Percepción de la validez del cuestionario Migraine Disability Assessment por una población de pacientes con migraña crónica / Perception of the validity of the Migraine Disability Assessment questionnaire in a population of patients with chronic migraine

Objetivos: El cuestionario Migraine Disability Assessment (MIDAS) es el instrumento más empleado para valorar el grado de discapacidad en los estudios de migraña. El objetivo del estudio es determinar el nivel de cumplimentación del cuestionario, valorar su facilidad de uso y conocer la percepción subjetiva del paciente sobre la capacidad del cuestionario para medir realmente su discapacidad.Material y métodosEstudio prospectivo sobre una población de 78 pacientes con migraña crónica. Se determina el nivel educativo y la situación laboral. En la visita basal se adiestra a los pacientes sobre la correcta cumplimentación del cuestionario. A los 3 meses se determina la puntuación total y el nivel de cumplimentación. Además los pacientes contestan una encuesta que mide: facilidad de uso y percepción del paciente sobre si la escala refleja su propia discapacidad.ResultadosSolo el 46% rellena completamente el cuestionario. El 69% de los pacientes indica que el cuestionario no les resulta fácil de cumplimentar (resultado no influido por el nivel educativo, pero sí por la situación laboral de los pacientes). El 62% de los encuestados opina que el cuestionario no refleja completamente su propia percepción de discapacidad.ConclusionesAunque está más que demostrada la validez y consistencia del cuestionario MIDAS, un porcentaje elevado de nuestra población reconoce que el cuestionario no es fácil de rellenar y además es percibido por muchos de nuestros pacientes como un cuestionario que no refleja adecuadamente su discapacidad. Conocer la opinión de los pacientes sobre la idoneidad de los cuestionarios administrados en las consultas es crucial para mejorar su cumplimentación. (AU)

Objectives: The Migraine Disability Assessment (MIDAS) questionnaire is the most frequently used instrument for assessing the level of disability in studies into migraine. This study aims to determine the level of completion of the questionnaire, assess the ease of use, and understand patients’ subjective perception of the questionnaire's actual ability to measure disability.Material and methodsWe performed a prospective study of a sample of 78 patients with chronic migraine, determining their level of education and employment status. In a baseline visit, patients were trained to properly complete the questionnaire. At 3 months, we determined the total score and level of completion. Patients also completed a survey measuring ease of use of the questionnaire and patients’ perception of whether the score accurately reflected their disability.ResultsOnly 46% of patients fully completed the questionnaire. Sixty-nine percent reported finding it difficult to complete (this was influenced by patient's employment status but not by educational level). Sixty-two percent of respondents believed that the questionnaire did not fully reflect their own perception of their disability.ConclusionsAlthough the validity and consistence of the MIDAS questionnaire are well documented, a high percentage of the study population reported finding it difficult to complete; many patients also considered that the questionnaire did not accurately reflect their disability. Understanding patients’ opinions of the suitability of questionnaires used in consultation is crucial to improving completion. (AU)

Reversible Homonymous Inferior Quadrantanopia in a Nonketotic Hyperglycemic Patient.

Homonymous hemianopia is frequently associated with retrochiasmal lesions. Vascular etiology is the most common and usually evident on magnetic resonance imaging. When the results of neuroimaging are normal, there are other etiologies that we should consider, like nonketotic hyperglycemia (NKH). We report a 62-year-old female diabetic patient with headache, colour vision and sudden homonymous inferior quadrantanopia and elevated blood sugar levels with normal pH. The neuroimaging was normal and the visual lost improved after the correction of the hyperglycemia. NKH should be considered in patients with sudden and transient hemianopia and normal neuroimaging.

Eyelid myokymia in patients with migraine taking topiramate.

OBJECTIVE: Although ocular side effects of topiramate are common, neuroophthalmologic manifestations such as blepharospasm, myokymia and oculogyric crisis are scarcely reported. METHODS: We present a serie of 8 patients with migraine who developed eyelid myokymia after treatment with topiramate. We reviewed all patients with migraine treated with topiramate attending the headache outpatient clinic of our hospital from January 2008 to December 2012. RESULTS: During the study period, a total of 140 patients with migraine were treated with topiramate in our headache clinic. Eight presented eyelid myokymia after beginning treatment with topiramate (5,7%). Topiramate was stopped and myokymia disappeared in all patients, it was prescribed again and eyelid myokymia reappeared with their previous characteristics in all patients. CONCLUSIONS: Eyelid myokymia is an underreported side-effect of topiramate in patients with migraine, of unknown cause, so that in future, further studies are need to examine whether patients with migraine are predisposed or not to this adverse effect.
