White matter (WM) is often severely affected after human ischemic stroke. While animal studies have suggested that various factors may contribute to WM structural damage after ischemic stroke, the characterization of damaging processes to the affected hemisphere after human stroke remains poorly understood. Thus, the present study aims to thoroughl...

Purpose The main aim of this study is to provide French Canadian reference data for quantitative measures extracted from connected speech samples elicited by the Western Aphasia Battery–Revised picnic scene, a discourse task frequently used in clinical assessment of acquired language disorders. Method Our sample consisted of 62 healthy French Cana...

Background Previous findings have demonstrated the importance of discourse analysis in post-stroke aphasia, as it allows for in-depth examination of language impairment and represents key components of functional communication. However, little is known about the recovery of discourse over time. Aims The main aim of this study is to measure the lon...

A longitudinal study of narrative discourse in post-stroke aphasia

Objective: The present study aims to assess the relationship between quantitative measures of connected speech production and performance in confrontation naming in early post-stroke aphasia (8-14 days post-stroke). Method: We collected connected speech samples elicited by a picture description task and administered a confrontation naming task to...

Background: Discourse analysis allows the examination of functional and ecological language impairment in post-stroke aphasia. Given its complexity, various methods of analysis have been developed to measure the multiple components of discourse. Clinical assessment usually includes discourse analysis, but how clinicians should assess recovery of di...

The stress-vulnerability-protective factors model is often used to explain the etiology and known risk and protective factors of initial psychotic symptoms and symptomatic relapses. Over the past 40 years since its initial conception, the model has evolved and gathered a plethora of evidence of varying quality for its different components. The obje...

Narrative discourse recovery in the acute stage of post-stroke aphasia

It is poorly understood whether and how normal aging affects different aspects of connected speech production, such as fluency, informativity, efficiency, and vocabulary use. The present study cross-sectionally investigates the effects of age on a broad variety of language production measures, using connected speech samples elicited by the two most...
