We report a case of probable Alzheimer's disease who presented with the unusual
feature of disinhibited rhyming. Core language skills were largely intact but
generative language was characterized by semantic-based associations, evident in
tangential and associative content, and phonology-based associations, evident in
rhyming, in the context of prominent executive dysfunction. We suggest this
pattern is underpinned by a failure to terminate or inhibit verbal associations
resulting in a 'loosening' of associations at the level of conceptual preparation
for spoken language.
