C. Double deficit dyslexia
Double deficit dyslexia is the term that they use for individuals that have phonological dyslexia and surface dyslexia.
D. Visual dyslexia and auditory dyslexia
These two kinds of dyslexia comes from the magnocellular theory of dyslexia. In this theory, people with dyslexia are neurologically weak in their magnocellular cells that can be found in the thalamus part of brain. The thalamus is where the auditory and visual information are processed.
There are studies that proves that people with dyslexia have difficulties in processing auditory information and visual information.
This means that children that have poor visual skills but have average hearing skills can be diagnosed as visual dyslexia, and those children that have poor hearing skills but average visual skills are diagnosed with auditory dyslexia.
E. Orthographic dyslexia
