As there are a variety of learning disabilities, there is no specific unifying cause. However, most learning disabilities arise from an underlying cognitive deficit that impairs the child’s ability to learn in that specific area.
For example, dyslexia, the most common learning disability, often arises from an underlying deficit in the child’s ability to process and manipulate sounds. On the other hand, dyscalculia, or difficulty in math, can come from underlying deficits in reasoning or visual-spatial understanding.
Both of these are overgeneralizations, as there are various types of dyslexia, dyscalculia, and dysgraphia, but there is often an underlying problem in the child’s neuropsychological makeup that accounts for the learning difficulty.
