Dyslexia can be broken down into three general categories.
1. The first category, visual dyslexia, is characterized by the tendency to reverse letter and number sequences, disorientation in time-space relationships, and other problems in processing, interpreting and recalling visual images.
2. The second, auditory dyslexia, creates problems in processing sound-based information.
3. The third category is a combination of visual and auditory dyslexia, in varying proportions specific to individual cases.
