The relationship between non-linguistic cognitive deficits and language recovery in patients with aphasia

Seniów, Joanna, Litwin, Marika, Leśniak, Marcin·2009·Journal of the Neurological Sciences

Abstract

Background and purpose Non-linguistic cognitive impairments may limit rehabilitation efficacy in patients with aphasia. The aim of this study was to determine whether post-stroke aphasia was associated with impairments of visuo-spatial working memory and abstract thinking and whether these deficits adversely affected language recovery.Methods Baseline visuo-spatial memory and abstract thinking abilities were assessed in 78 patients with post-stroke aphasia and 38 healthy controls. Then, 47 of the 78 patients with aphasia completed three weeks of speech and language training. Therapy outcome was assessed by comparing pre- and post-treatment scores on the Boston Diagnostic Aphasia Examination.Results Even though the patients' non-linguistic cognitive abilities were impaired in general, the patients were heterogeneous with regard to their deficits. Linguistic and non-linguistic deficits appeared to be distinct, although they could be concurrent. Visuo-spatial working memory was associated with the degree of improvement in two functions crucial to language communication: naming and comprehension. No relationship was found between language therapy outcome and abstract thinking ability.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Age influences inter-individual variability in treated language improvement in post-stroke aphasia.

    “It is well established that inter-individual variability in TLI in post-stroke aphasia is influenced by an array of factors, including, but not limited to, age12–15, education16–19, aphasia severity11,14,15,20,21, baseline cognitive abilities13,22,23, and, specific to bPWA, bilingual language experience and language of treatment (e.g., whether therapy is delivered in L1 or L2)24,25.”
  • Baseline cognitive abilities influence inter-individual variability in treated language improvement in post-stroke aphasia.

    “It is well established that inter-individual variability in TLI in post-stroke aphasia is influenced by an array of factors, including, but not limited to, age12–15, education16–19, aphasia severity11,14,15,20,21, baseline cognitive abilities13,22,23, and, specific to bPWA, bilingual language experience and language of treatment (e.g., whether therapy is delivered in L1 or L2)24,25.”
  • Previous studies demonstrate the impact of cognitive factors, such as attention, memory, and executive function, on treatment-induced language recovery in monolingual aphasia.

    “This finding resonates with previous studies demonstrating the impact of cognitive factors, such as attention, memory, and executive function, on treatment-induced language recovery in monolingual aphasia13,22,23.”
  • The influence of cognitive factors on treatment outcomes has been found in monolingual aphasia studies, with stronger skills conferring better outcomes.

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.
