This is mediated through the angular gyrus, which provides the linguistic rules which guide writing. The motor stage is where the expression of written words or graphemes is articulated. This stage is mediated by Exners writing area of the frontal lobe.The condition can cause individuals to struggle with feedback and anticipating and exercising control over rhythm and timing throughout the writing process.People with dysgraphia can often write on some level and may experience difficulty with other activities requiring reciprocal movement of their fingers and other fine motor skills, such as; tying shoes, fastening buttons or playing certain musical instruments. However, dysgraphia does not affect all fine motor skills. People with dysgraphia often have unusual difficulty with handwriting and spelling which in turn can cause writing fatigue. Unlike people without transcription disabilities, they tend to fail to preserve the size and shape of the letters they produce if they cannot look at what they are writing. They may lack basic grammar and spelling skills (for example, having difficulties with the letters p, q, b, and d), and often will write the wrong word when trying to formulate their thoughts on paper. The disorder generally emerges when the child is first introduced to writing. There is accumulating evidence that in many cases individuals with SLDs and DCD do not outgrow their disorders. Accordingly, it has been found that adults, teenagers, and children alike are all subject to dysgraphia.
While IDEA does not use the term "dysgraphia", it describes it under the category of "specific learning disability". This includes issues with understanding or using language (spoken or written) that make it difficult to listen, think, speak, read, write, spell or to do mathematical calculations. See also
