With dysgraphia, the brain has difficulty translating thoughts into writing with the speed and accuracy expected at that age. Correspondingly, written language comprises letters, written words, sentences, and text. In a previous post, I operationalized "dyslexia" as inefficiencies in the linguistic system in the brain, much of which also apply to dysgraphia. And like dyslexia, dysgraphia may affect an estimated 20% of the population (Chung et al., 2020). This is because it can result from inefficiencies in different parts of the linguistic system or the other brain systems.
