Dyslexia is a learning disorder that affects one's ability to read, spell, and write. It is not a result of poor vision or intelligence but rather a difference in the way the brain processes language. Individuals with dyslexia may have difficulty with phonological awareness, decoding words, and recognizing word patterns. Treatment typically involves structured literacy instruction and accommodations to support learning.
