General Learning Disabilities is a broader term than “Special Learning Disabilities” and is often misused. In contrast, “Special Learning Disabilities” as a specific term refers to a category of disorders (which probably have a neurobiological basis), which cause “difficulty in acquiring one or more learning areas related to the processing of speech in language and mathematics (e.g. .x in reading, comprehension of written speech, difficulty in arithmetic, etc.).
Also often through an arbitrary generalization the special learning difficulties are identified with the term “Dyslexia”.
Dyslexia, however, refers to only one specific category of special learning difficulties, that of difficulty in learning the reading process and spelling. Other categories of special learning difficulties include dysgraphia, dysgraphia and dysnumeracy. The criterion for differentiating the two major categories is in our view on the one hand the extent of the problem during the learning process and on the other hand the typology of the etiology.
