The impact of linguistic deficits on verbal communication | Semantic Scholar (2024)

The relative impact of semantic and phonological deficits on verbal communication is explored and the results of both diagnostic and therapeutic studies in patients with aphasia after stroke are presented.

The findings challenge the current notion that semantic treatment is more effective than phonological treatment for patients with a combined semantic and phonological deficit and suggest that improved verbal communication was achieved in a different way for each treatment group.

These findings endorse the incorporation of discourse-level tasks into aphasia assessment and treatment protocols and use of simple and easily quantifiable measures (e.g., %WR) may be an option to extend current methodology and reconcile issues of ecological validity and clinical feasibility.

Repeated systematic treatment can produce a significant improvement in verb retrieval of practised items and generalise to unpractised items for some participants.

The ScreeLing was found to be valid and reliable for assessing the presence and severity of aphasia and linguistic deficits at 12 days after stroke and linguistic-level deficits are already present independently of each other, with phonology affected most frequently.

The conclusion is the individual with global aphasia who experienced the language rehabilitation within a year still faced some difficulties on language utterance, but the subject still can communicate with normal people.

This easy to administer test gives information about language processing with the potential to improve differential diagnosis in memory clinics and in the future potentially also clinical trial planning.

The natural course and prognosis of aphasia after stroke is addressed in a large Dutch multicenter prospective study, the Sequential Prognostic Evaluation of Aphasia After Stroke study, known as the SPEAK study.

The main objective of this study was to investigate whether adults with post-stroke aphasia could learn ‘novel’ word forms with 'novel' word meanings, despite phonological and/or semantic impairment, despite semantic and phonological difficulties.

A prognostic model of verbal communication can be used to inform patients with moderate-to-severe aphasia and their families about the expected recovery of verbal communicative ability after inpatient rehabilitation, and it may guide clinicians, patients, and their relatives in shared decisions on the most appropriate treatment approach to improve functional communication.

R.W.'s performances in short-term memory and metalinguistic tasks involving single words were consistent with impaired rehearsal functions and the pattern of results indicates that rehearsal requires planning of the phonological forms of spoken items and suggests that activating entries in the phonology output lexicon is not adequate to permit rehearsal to proceed normally.

This study confirms the existence of separable deficits in semantic comprehension and points conclusively to the left posterior temporal and inferior parietal region as being critical for semantic processing.

A model of word reading incorporating lexical, nonsemantic processes by which lexical orthographic input representations directly activate lexical phonological output representations without the necessity of semantic mediation is supported.
