NLP-Oriented Contrastive Study of Linguistic Productions of Alzheimer’s and Control People

Exploring Stylistic Variation with Age and Income on Twitter

“…Both attributes should be closely related to writing style: users of older age write on average more standard-conform (up to a certain point), and higher income is an indicator of education and conscientiousness (Judge et al, 1999), which determines writing style. Indeed, many features that aim to measure the complexity of the language use have been developed in order to study human cognitive abilities, e.g., cognitive decline (Boyé et al, 2014;Le et al, 2011).…”

Intranasal Insulin as Promising Therapy for Preserving Pragmatic Competence in MCI and AD

“…In MCI and AD, impairments in the dorsal stream of visual perception and processing have been found to be a predictor of AD [28]. Increasing impairment in visuospatial skills, visual object processing, and visual recognition of human emotion processing are common on test scores of AD patients as part of annual cognitive deterioration [29][30][31].…”

Cognitive impairment and pragmatics

“…According to Wray ( 2015b ), language processing is undermined by damage to the language areas of the brain. NLP features (lexicon, syntax errors) are evident in the natural speech of even early Alzheimer’s patients, as AD persons produce syntactically poorer sentences, mention lesser number of ideas and words, produce redundant, less precise and informative discourse; there is also rare use of the modalizers, and pronouns miss their intended reference, which implies a loss of the semantic cohesion (Boyé et al 2014 :4). The progressive loss of ability to communicate begins with early AD language deficits (word substitutions, aborted phrases), then progresses to comprehension deficits, paraphasic errors, and semantic jargon in mid-to-late stage Alzheimer (Tappen et al 2002 :63).…”

“…The progressive loss of ability to communicate begins with early AD language deficits (word substitutions, aborted phrases), then progresses to comprehension deficits, paraphasic errors, and semantic jargon in mid-to-late stage Alzheimer (Tappen et al 2002 :63). Semantic and lexical speech features are multiple and include stutters, self-corrections, incomplete sentences, a greater number of empty pauses and lesser number of non-empty pauses or a very high percentage of personal pronouns (Boyé et al 2014 ). Speech becomes formulaic and the patient might produce appropriate utterances even when there is doubt about whether they are really meant (Wray 2013 ; Hamilton 1994 ).…”
