How common is agraphia?
Pure agraphia, or agraphia as an isolated symptom, is quite rare. Often, however, agraphia appears to be the consequence of neurological or cognitive dysfunction that spares linguistic processing skills. Writing impairments are almost inevitable when motor systems of the brain are affected.
What causes aphasia in stroke?

Does Broca’s aphasia affect writing?
