Acquired dysgraphia with selective damage to the graphemic buffer: a single case report

We describe one patient with acquired dysgraphia who showed spelling errors (mainly deletions and substitutions), both for words and non-words, across all output modalities (oral and written spelling, and delayed copying). Spelling accuracy was not affected by lexical factors, but was a function of word length. The patient's performance in oral and written tasks suggests the hypothesis of selective damage to the Graphemic Buffer.
