Alteration in MCI and ad concerning phonetics, phonology, lexicon, semantics, and pragmatics.
Examination methods | Examination results | Sensitivity measures | Reference |
---|---|---|---|
Phonetics and phonology | |||
Temporal analysis of spontaneous speech | Mild AD and CTRL differ in speech tempo and hesitation ratio | No data | Hoffmann et al. (2010) |
Temporal analysis of speech, oral reading task | Distinguishes moderate AD and CTRL. Best two parameters: speech tempo and articulation tempo | 80% | Martínez-Sánchez et al. (2013) |
Spoken task; speech-based detection | Might be a good method for detecting early AD | CTRL and MCI: 80% | Satt et al. (2014) |
MCI and AD: 87% | |||
Automatic spontaneous speech analysis | Distinguishes between AD and CTRL | No data | López-de-Ipiña et al. (2013) |
Lexicon, semantics and pragmatics | |||
Semantic association test | AD performs significantly worse than CTRL | No data | Visch-Brink et al. (2004) |
Semantic verbal fluency and phonological verbal fluency | Good tool for diagnosis of early AD | No data | Laws et al. (2010) |
Picture naming, semantic probes, lexical decision and priming, Stroop-picture naming | AD group was impaired in semantic tasks | No data | Duong et al. (2006) |
Verbal task | AD group produces shorter texts, less relevant information and multiple error types than CTRL | No data | Taler and Phillips (2008) |
AD, Alzheimer’s disease; MCI, mild cognitive impairment; CTRL, healthy controls.
