There are three types of dyslexia; dysphonetic, dyseidetic or a combination of both. Here are some signs of each.
The terms 'dysphonetic' and 'dyseidetic' are words used to describe typical symptoms of dyslexia. The person labeled 'dysphonetic' has difficulty connecting sounds to symbols, and might have a hard time sounding out words, and spelling mistakes would show a very poor grasp of phonics. This is also sometimes called "auditory" dyslexia, because it relates to the way the person processes the sounds of language.
The 'dyseidetic' individual, on the other hand, generally has a good grasp of phonetic concepts, but great difficulty with whole word recognition and spelling. This type of dyslexia is also sometimes called "surface dyslexia" or "visual dyslexia."
