disorder of written expression
in DSM–IV–TR, a learning disorder in which writing skills are substantially below those expected for a person’s chronological age, education, and measured intelligence. The writing difficulties—which may involve errors in grammar, punctuation, and paragraph organization, often combined with extremely poor handwriting and spelling errors—significantly interfere with academic achievement and activities of daily living that require writing skills. In DSM–5, the disorder has been subsumed within a category labeled specific learning disorder and is no longer considered a distinct diagnosis. Also called developmental dysgraphia.
