Disability or not?

Have you seen the show George Lopez? I just started watching this show recently and I saw an episode where George’s son Max is diagnosed with dyslexia. George is also dyslexic but I am more concerned about Max’s situation. The teacher talks to George about the situation and suggests that he is put in special education classes. This really bothers me. Special education classes, from my experience, are for those students who have a serious learning and/or behavioral problems. In this situation, Max is a fairly decent student who has never had any behavioral at home or in school. What my issue is, is that yes he has dyslexia but he is all of a sudden being treated as if he has a serious disability. What is the definition of disability? According to dictionary.com a disability is ‘a physical or mental handicap, esp. one that prevents a person from living a full, normal life or from holding a gainful job.” As far as I know, dyslexia does not hold a person back. My nephew is dyslexic and for years he had trouble in school and depending on what school he attended he could take regular or special needs classes. It was not until he was about eight that he was diagnosed with dyslexia. He never had any behavioral problems but he did slightly fall behind academically. However, after they realized this was his problems, they simply reworded his work. He did the same material as the rest of the class, but on assignments his questions would be worded in a way that might be confusing to someone without dyslexia. Once they figured this out, he caught up to his level very quickly. So what I am getting at, is if something as simple as rephrasing assignments could help, why are certain school systems sending these children to special education classes. I understand that this condition calls for some extra help, but I do not think that it should be considered a disability, at least not to the extreme in which many school systems consider it.
