Aphasia in Alzheimer's disease and other dementias (ADOD): Evidence from Chinese

Open access
Weekes, Brendan Stuart Hackett·2020·American Journal of Alzheimer's Disease & Other Dementias®

Abstract

Speech and language impairments (aphasia) are typical of patients with Alzheimer's Disease and other dementias (ADOD) and in some pathologies are diagnostic e.g. Primary Progressive Aphasia (PPA). One question concerns the reliability and validity of symptomatology across typologically different languages. A review of aphasia in ADOD across languages suggests a similar pattern of word comprehension, naming and word finding difficulties but also evidence of language specific features in symptomatology e.g. processing of tone in Chinese languages. Given differences in linguistic impairments across languages, it is recommended that screening for aphasia in community and epidemiological studies use a Short ScreeningTest (SST) that can be delivered across dialects and languages in indigenous languages and also multilingual populations.

  • The Comprehensive Aphasia Test is available in Basque, Catalan, Croatian, Cypriot Greek, English, French, Greek, Hungarian, Norwegian, Serbian, Spanish, Swedish and Turkish.

    “For example, the Comprehensive Aphasia Test, which spans over 20 subtests of receptive and productive skills, is available in Basque, Catalan, Croatian, Cypriot Greek, English, French, Greek, Hungarian, Norwegian, Serbian, Spanish, Swedish and Turkish. 80,118”
  • Validated tools are unavailable for most languages.

    “Moreover, validated tools are unavail able for most languages”
  • Translations of tests developed for English may overlook language-specific markers of these syndromes, compromising diagnosis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
