One way to investigate the neuronal underpinnings of language competence is to correlate patholinguistic profiles of aphasic patients to corresponding lesion sites. Constituting the beginnings of aphasiology and neurolinguistics over a century ago, this approach has been revived and refined in the past decade by statistical approaches mapping continuous variables (providing metrics that are not...

Background: Within cognitive neuropsychological models, conduction aphasia has been conceptualized as a phonological buffer deficit. It may affect the output buffer, the input buffer, or both. The phonological output buffer is a short-term storage, responsible for the short-term maintenance of phonological units until their articulation, as well as for phonological and morphological composition...

Objectives: The purpose of this study was to investigate the differential performance on musical chord and grammaticality judgement tasks in post-stroke aphasia. accuracy task were analyzed, correlation between severity aphasia examined. Methods: Fourteen individuals with fifteen adults without participated study. subject listened a presented voice asked determine whether connection natural the...

Patients with the semantic variant of primary progressive aphasia, also known as semantic dementia, and Alzheimer's disease have deficits in semantic memory. However, few comparative studies have been performed to determine whether these patient groups have distinct semantic memory impairments. We asked 15 patients with semantic variant primary progressive aphasia and 57 patients with Alzheimer...

fat embolism syndrome is a clinical diagnosis, and diagnostic procedures are not specific. in every trauma patient, fat embolism syndrome has to be considered as a possibility and supportive treatment should begin as soon as possible. the authors reported a rare case of fat embolism syndrome whose only neurological symptom was motor aphasia. a young man sustained comminuted femoral shaft fractu...

Background: Overall, there is growing consensus that working memory (WM) should be routinely assessed in individuals with aphasia as it can contribute significantly to their level of language impairment and be an important factor in treatment planning. However, there is still no consensus in the field as to which tasks should be used to assess WM in aphasia. The two main alternatives are adapte...

BACKGROUND Speech segmentation is one of the initial and mandatory phases of language learning. Although some people with aphasia have shown a preserved ability to learn novel words, their speech segmentation abilities have not been explored. AIMS We examined the ability of individuals with chronic aphasia to segment words from running speech via statistical learning. We also explored the rel...

BACKGROUND Very early aphasia rehabilitation studies have shown mixed results. Differences in therapy intensity and therapy type contribute significantly to the equivocal results. AIMS To compare a standardized, prescribed very early aphasia therapy regimen with a historical usual care control group at therapy completion (4-5 weeks post-stroke) and again at follow-up (6 months). METHODS & P...

Global aphasia is an acquired language disorder characterized by severe impairments in all modalities of language. The specific sites of injury commonly include Wernike's and Broca's areas and result from large strokes--particularly those involving the internal carotid or middle cerebral arteries. Rarely, deep subcortical lesions may cause global aphasia. We present three cases with global apha...
