Dyslexia, Dysgraphia, and Dyscalculia are often present in children who have auditory or visual processing deficits and/or underlying deficits in specific cognitive skills like coding/decoding, sequencing, part/whole relationships and auditory or visual discrimination.
Dyslexia is a general term for disorders that involve difficulty in learning to read or interpret words, letters, and other symbols, but that do not affect general intelligence.
Dysgraphia is a term that refers to trouble with writing; handwriting, typing, and spelling manifesting as the general ability to produce writing; NOT the trouble expressing your thoughts in writing.
Dyscalculia is a term used to describe specific learning disabilities that affect a child’s ability to understand, learn, and perform math and number-based operations. This is not to be confused with difficulty with mathematical word problems which generally is not a math and number issue, but rather a reading / reading comprehension issue.
