Sometimes referred to agraphia, it is an impairment in the ability to express thoughts in writing and to write clearly (e.g., mixture of upper and lower case letters, dysfunctional writing grip), regardless of the ability to read. Often associated with other problems in movement coordination (e.g., tying shoelaces), and therefore with apraxia, developmental dyspraxia and developmental coordination disorder, as well as with dyslexia. Three types of dysgraphia are distinguished: dyslexic dysgraphia (spontaneous written work illegible, spelling poor), motor dysgraphia (illegible spontaneous and copied work, normal spelling), and spatial dysgraphia (problems in recognizing the shapes of letters in both spontaneous and copied work). As with dyslexia, a distinction is made between acquired and developmental dysgraphia.
