Background: Although existing studies have shown that both repetitive transcranial magnetic stimulation (rTMS) and music therapy have advantages in the treatment of non-fluent aphasia, the efficacy of the combination of these two methods remains to be investigated. Aims: To investigate the clinical efficacy of low-frequency rTMS combined with…

Background: Discourse analysis has recently received much attention in the aphasia literature. Even if post-stroke language recovery occurs throughout the longitudinal continuum of recovery, very few studies have documented discourse changes from the hyperacute to the chronic phases of recovery. Aims: To document a multilevel analysis of discourse…

Purpose: Communication access is a human right, but many individuals with communication impairments face challenges accessing their environments. As part of a larger study investigating barriers and facilitators to communication access in the retail/service industry, the purpose of the present study was to investigate the experiences of people…

Background: The most common cause of aphasia is a left middle cerebral artery stroke affecting the left perisylvian region of the brain. The perisylvian region is critical for supporting phonological processing, and damage to this region results in difficulty with retrieving and manipulating speech sounds. The impact of weakened phonology has been…

Aphasia, language disorder after acquired brain injury, is a chronic condition negatively impacting functional communication and quality of life. More than two million individuals in the United States have aphasia and the most common cause of aphasia is stroke. Further understanding of post-stroke aphasia will ultimately allow for development of…

The goal of this dissertation was to find converging evidence from behavioral and neuroimaging analyses of the mechanisms of orthographic integration with general language processes. By examining orthography effects, covert influences of orthography on non-written tasks, in participants with aphasia, we attempt to elucidate the nature of…

Sentence comprehension requires both syntactic prediction and working memory processes. Evidence suggests that both are impaired in agrammatic aphasia, and can independently contribute to comprehension breakdowns, but the relationship between them, especially during real-time sentence comprehension remains unclear. Two EEG studies investigated…

Background: The communicative effectiveness of persons with aphasia (PWA) has been assessed through a range of functional communication measures. However, variability in interpretations of what is covered by the term "functional communication" may have resulted in challenges to the implementation of appropriate and consistent…

Background: Gesture and speech collaborate in conveying meaning, and gesture is often leveraged by people with neurogenic communication disorders, such as aphasia, cognitive-communicative impairments and primary progressive aphasia, when words fail them. Because gesture is imagistic, transitory and holistic, there are inherent challenges when…

Background: The term progressive apraxia of speech (PAOS) is used to describe speakers presenting with isolated or dominant apraxia of speech in the context of a neurodegenerative syndrome, including primary progressive apraxia of speech (PPAOS) and dominant progressive apraxia of speech (DAOS), respectively. Its motor speech profile has been…

Neuromyelitis optica spectrum disorder (NMOSD) is an acquired neurological disorder primarily affecting physical and visual functioning. There is a lack of empirical evidence in the existing literature about the nature of speech, language, and cognitive deficits associated with NMOSD. Hence, this case study provides assessment information about a…

Purpose: This study investigated conflict adaptation in aphasia, specifically whether upregulating cognitive control improves sentence comprehension. Method: Four individuals with mild aphasia completed four eye tracking sessions with interleaved auditory Stroop and sentence-to-picture matching trials (critical and filler sentences). Auditory…

Background: People with aphasia (PWA) typically exhibit deficits in spoken discourse. Discourse analysis is the gold standard approach to assess language deficits beyond sentence level. However, the available discourse assessment tools are biased towards English and European languages and Western culture. Additionally, there is a lack of consensus…

Rett syndrome (OMIM #312750) is a progressive neurodevelopmental disease with clinical manifestations including loss of spoken language and apraxia. We summarized per PRISMA guidelines findings on their non-verbal social skills. Twelve studies (n = 479 females, 1.6-52 years) were sorted into a (non-)interventional design including video-coding,…

Background: Aphasia, a common consequence of stroke, which affects both communication and social functioning, and in turn, quality of life, is on the rise due to increases in stroke prevalence and survival rate. The rehabilitation of post-stroke aphasia primarily falls within the purview of speech-language pathology and research supports the…
