Which statement accurately defines dyslexia?

Dyslexia is accurately defined as a language-based disability that impacts both oral and written language. This condition primarily affects the individual’s ability to read, write, and spell due to difficulties in processing the sounds of language. Individuals with dyslexia often struggle with phonemic awareness, which is crucial for decoding words.

This definition encompasses the extent of dyslexia's influence on a person's language processing capabilities. Unlike cognitive disabilities that may restrict verbal communication alone, dyslexia involves a broader difficulty with language functionality. Furthermore, it is not limited to young children, as it can persist into adulthood, which rules out the idea of it being a minor difficulty found solely in early developmental stages. Dyslexia also does not refer specifically to mathematical learning disorders, which is a separate category of learning challenges.

Thus, the comprehensive nature of dyslexia's impact on both reading and writing—signifying that it affects overall language skills and not just one aspect of communication—makes this understanding of the condition the most accurate.
