Dyslexia is a type of learning disorder that affects the ability to read, spell, write and speak. People with dyslexia often have trouble reading fluently as they are slow readers and often make mistakes, affecting their comprehension skills. However, they have no problem understanding the concept when other people read to them.
This points out that dyslexia is an issue with language and not with intelligence. They are just as smart as their peers and with the correct teaching strategies they can effectively manage the challenges faced in reading and writing.
