Nombres alternativos

Dislexia

Definición:

Es una dificultad para leer que ocurre cuando el cerebro no reconoce ni procesa apropiadamente ciertos símbolos.

Causas, incidencia y factores de riesgo:

La dislexia o trastorno del desarrollo de la lectura ocurre cuando hay un problema en áreas del cerebro que ayudan a interpretar el lenguaje y no es causado por problemas de visión. El trastorno es un problema de procesamiento de información específica que no interfiere con la capacidad de uno para pensar o entender ideas complejas. La mayoría de las personas con este trastorno tienen inteligencia normal y muchos tienen una inteligencia por encima del promedio.

El trastorno del desarrollo de la lectura puede aparecer en combinación con el trastorno del desarrollo de la escritura y el trastorno del desarrollo aritmético. Todos estos procesos implican el uso de símbolos para transmitir información. Estas afecciones pueden aparecer aisladamente o en cualquier combinación.

La dislexia a menudo es hereditaria.
