Authors and the dissolution of language in Alzheimer's Disease

A number of my very favorite authors have been impacted by Alzheimer's Disease or associated disease variants.  Gabriel Garcia Marquez, W. Somerset Maugham, and Terry Pratchett are among the most prominent that come to mind.  Dr. Peter Garrard wrote a brilliant article pubmed link here on the dissolution of narrative in the work of Dame Iris Murdoch, a renowned British author. As I revisit Dr. Garrard's work, I wonder if world class expertise in writing (or other creative pursuits) would respond uniquely to cognitive treatment or require a tailored approach.  We have been working on a treatment targeting lexical preservation in progressive conditions like these (e.g., progressive nonfluent aphasia, semantic dementia).  I wonder how this approach would work among high level writers -- perhaps pairing behavioral treatment with an acetylcholinesterase inhibitor.  Email if you have any thoughts on this.
