Alzheimer’s disease (AD) is a progressive neurological disease that
leads to deterioration in cognitive abilities. People with AD encounter
a progressive decline in their neurological capabilities, which
manifest in language deficits, among other cognitive difficulties. The
main failures in speech include naming difficulties, verbal fluency
deficit, comprehension problems, and deterioration of spontaneous
speech. The speech of people with AD is usually considered “empty”
– it contains a high proportion of words and utterances that convey
little or no information compared to the speech of elderly people
without AD (Kavè & Levy, 2003). People with AD tend to have “discourse
deficits”, which include empty phrases, indefinite words, and

for an interlocutor to follow. Thus, these progressive language
failures can lead people with AD to isolation
