NEUROIMÁGENES EN DEMENCIAS

Abstract

RESUMENLas demencias constituyen un problema severo de salud a nivel mundial, y describen una gran cantidad de síntomas. Se caracterizan por un deterioro cognitivo adquirido irreversible que afecta principalmente, pero no exclusivamente, la memoria. Además, afecta especialmente a las personas mayores, pero no constituye una consecuencia normal del envejecimiento. Existen múltiples técnicas imagenológicas que apoyan el diagnóstico, que están en etapa de investigación o que se utilizan actualmente en el aspecto clínico. Protocolos estándar de imágenes de resonancia magnética, escalas de evaluación visual de la atrofia, técnicas de volumetría cerebral, paradigmas de resonancia magnética funcional, técnicas de conectividad funcional de reposo, SPECT y PET son las técnicas que se comentarán en este artículo.SUMMARYDementias correspond to a severe worldwide health problem, and it involves many symptoms. Dementias are characterized by an irreversible cognitive decline that affects mainly, but not exclusively, the memory. Dementias mainly affects elderly people, but it is not a normal consequence of aging. There are multiple imaging techniques that support the diagnosis of dementias: some are in clinical use, and other are research techniques. Magnetic resonance imaging standard protocols, visual assessment scales atrophy, cerebral volumetry techniques, fMRI paradigms, resting state functional connectivity, SPECT and PET are the techniques discussed in this article.
