En la investigaci\u00f3n sobre el s\u00edndrome de fatiga cr\u00f3nica, los pacientes la describen como pensar despacio, dificultad para concentrarse, confusi\u00f3n, olvidar cosas y un velo sobre el pensamiento. En las pruebas, los investigadores ven en estas personas sobre todo un procesamiento de la informaci\u00f3n m\u00e1s lento y menos eficiente, menos atenci\u00f3n y una memoria de trabajo m\u00e1s peque\u00f1a.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">1<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De 138 personas de entre 14 y 29 a\u00f1os con un trastorno de la circulaci\u00f3n sangu\u00ednea que rellenaron un cuestionario, 132 declararon niebla mental. Esas 132 describieron su niebla con m\u00e1s frecuencia como \u00abolvidadizo\u00bb, \u00abborroso\u00bb y \u00abdificultad para concentrarse, pensar y hablar\u00bb, y como desencadenantes nombraron el cansancio (91 por ciento), dormir poco (90 por ciento) y la deshidrataci\u00f3n (86 por ciento).\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">3<\/a><\/sup> Esa lista es lo esencial: la niebla mental es una experiencia de tu pensamiento, y esa experiencia se mueve con tu sue\u00f1o, tu tensi\u00f3n y tu cuerpo.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"waar-hersenmist-vandaan-komt\">De d\u00f3nde viene la niebla mental<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">El primer sitio donde mirar es tu noche. Un metaan\u00e1lisis de setenta estudios con 147 pruebas mostr\u00f3 que la falta breve de sue\u00f1o golpea con m\u00e1s fuerza la atenci\u00f3n simple: esos momentos en los que durante un instante no registras nada.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">4<\/a><\/sup> No hace falta una noche en vela. Quien durmi\u00f3 seis horas durante catorce noches rend\u00eda al final como si llevara hasta dos noches sin dormir, y apenas notaba m\u00e1s somnolencia.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">5<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La segunda es la tensi\u00f3n. La parte delantera de tu cerebro, la que dirige tu memoria de trabajo y tu atenci\u00f3n, es de todas las zonas cerebrales la m\u00e1s sensible al estr\u00e9s: incluso un estr\u00e9s leve sobre el que no tienes control puede reducir esas capacidades de forma r\u00e1pida y marcada.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">6<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La tercera es la menopausia. En un metaan\u00e1lisis, las mujeres que ya hab\u00edan pasado la menopausia puntuaron peor al recordar palabras despu\u00e9s de una pausa que las mujeres de antes de la menopausia o que estaban en ella, y la probabilidad de s\u00edntomas de \u00e1nimo bajo era mayor durante y despu\u00e9s de la menopausia.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">7<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La cuarta es una infecci\u00f3n pasada. De 81.337 personas que hicieron una prueba cognitiva en l\u00ednea, las que hab\u00edan tenido covid rindieron peor que quienes no lo hab\u00edan tenido, incluso cuando ya no ten\u00edan s\u00edntomas.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">8<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La quinta es tu estado de \u00e1nimo. Quien juzga mal su propio pensamiento a menudo no punt\u00faa peor en una prueba: la relaci\u00f3n entre las quejas y el rendimiento medido es peque\u00f1a, y las quejas en s\u00ed mismas van unidas a sentimientos de \u00e1nimo bajo.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">2<\/a><\/sup> Eso no hace que la queja sea menos real. Dice d\u00f3nde tienes que buscar normalmente.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"wat-een-breinscan-meet\">Qu\u00e9 mide un esc\u00e1ner cerebral<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">El esc\u00e1ner cerebral hace cuatro preguntas sobre las \u00faltimas dos semanas: la niebla mental, mantener la concentraci\u00f3n, los olvidos de cada d\u00eda y si pensar te cuesta esfuerzo. Cada pregunta recibe puntos, los puntos se suman y se convierten en una puntuaci\u00f3n de concentraci\u00f3n de 0 a 100, con la banda de lectura en la que cae. M\u00e1s alto es mejor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Las preguntas est\u00e1n modeladas a partir de cuestionarios sobre la cognici\u00f3n diaria percibida. El m\u00e1s conocido, el Cognitive Failures Questionnaire, pregunta desde 1982 por los fallos de cada d\u00eda al percibir, al recordar y al actuar; la puntuaci\u00f3n es tan estable como un rasgo de car\u00e1cter y coincide con lo que una pareja dice de ti.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">9<\/a><\/sup> Nuestras preguntas son de formulaci\u00f3n propia, no una copia, y por eso la puntuaci\u00f3n no es una puntuaci\u00f3n cl\u00ednica validada. La llamamos una puntuaci\u00f3n percibida, y la leemos junto a tu sue\u00f1o y tu bienestar en lugar de por s\u00ed sola.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"wat-een-breinscan-niet-meet\">Qu\u00e9 no mide un esc\u00e1ner cerebral<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">El pensamiento percibido no es el pensamiento medido. No hay una manera honesta de medir el rendimiento cognitivo con un cuestionario; lo que registra un autoinforme es c\u00f3mo se siente tu pensamiento, y eso guarda solo una relaci\u00f3n d\u00e9bil con lo que punt\u00faas en una prueba.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">2<\/a><\/sup> Por eso el esc\u00e1ner cerebral no es una prueba cognitiva ni un cribado de un trastorno de la memoria o de la atenci\u00f3n, y no hace ning\u00fan diagn\u00f3stico. Un cambio repentino y claro en tu memoria o en tu lenguaje, o una niebla que empeora en lugar de ir y venir, es cosa de un m\u00e9dico y no de una puntuaci\u00f3n.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"wat-je-met-je-score-doet\">Qu\u00e9 haces con tu puntuaci\u00f3n<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Una puntuaci\u00f3n baja suele apuntar al sue\u00f1o, a la tensi\u00f3n o al estado de \u00e1nimo, y esa es una noticia \u00fatil: ah\u00ed puedes hacer algo, y el efecto lo puedes medir. La puntuaci\u00f3n de hoy es tu valor de partida. Repite el esc\u00e1ner dentro de dos semanas, con las mismas preguntas, y ya no tendr\u00e1s una sensaci\u00f3n sobre tu cabeza, sino dos n\u00fameros.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si quieres cambiar algo en esas dos semanas, empieza por tus noches.
