What are the different types of dysgraphia?

While dysgraphia may be broadly classified as follows, there are many individual variations that affect both treatment and prognosis:

1. In dyslexic dysgraphia, spontaneously written text is illegible, espceially when the text is complex.  Oral spelling is poor, but drawing and copying of written text are relatively normal.  Finger-tapping speed (a measure of fine motor speed) is normal.
2. In motor dysgraphia, both spontaneously written and copied text may be illegible, oral spelling is normal, and drawing is usually problematic.  Finger-tapping speed is abnormal.
3. In spatial dysgraphia, people display illegible writing, whether spontaneously produced or prepared.  Oral spelling is normal.  Finger-tapping speed is normal, but drawing is very problematic.
