Dysgraphia is a neurological disorder and learning disability that concerns impairments in written expression, which affects the ability to write, primarily handwriting, but also coherence. It is a specific learning disability (SLD) as well as a transcription disability, meaning that it is a writing disorder associated with impaired handwriting, orthographic coding and finger sequencing (the movement of muscles required to write). It often overlaps with other learning disabilities and neurodevelopmental disorders such as speech impairment, attention deficit hyperactivity disorder (ADHD) or developmental coordination disorder (DCD).
In the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), dysgraphia is not mentioned. Dyslexia is characterized as a neurodevelopmental disorder under the umbrella category of specific learning disorder.
