		  to changes in language that can be detected by
		  computational analysis. These changes may include a
		  reduced, vaguer, and more abstract vocabulary, and reduced
		  syntactic complexity. But do these changes affect an
		  author's essential style? We experiment with a number of
		  standard features for authorship attribution and authorship
		  verification to see whether they recognize late works
		  written by authors known to have had Alzheimer's disease as
		  being by the same author as their earlier works. The
		  authors whom we study are Iris Murdoch and Agatha Christie.
		  Our control author (without Alzheimer's) is P.D. James. Our
		  results were equivocal, as different frameworks yielded
		  contrary results, but an SVM classifier was able to make
		  age discriminations, or nearly so, for all three authors,
		  thereby casting doubt on the underlying axiom that an
		  author's essential style is invariant in the absence of
		  cognitive decline.},
