Time reference, morphology and prototypicality: tense production in stroke aphasia and semantic dementia in Greek.

Time reference, morphology and prototypicality: tense production in stroke aphasia and semantic dementia in Greek. Clin Linguist Phon. 2019 Dec 09;:1-35 Authors: Koukoulioti V, Stavrakaki S, Konstantinopoulou E, Ioannidis P Abstract The present study aims at investigating verb inflection in aphasia and semantic dementia. In particular, it addresses the contribution of time reference and morphological complexity. Moreover, it investigates whether the lexical properties of the verb, such as argument structure and lexical aspect interact with the production of tense. Ten individuals with (different types of) stroke aphasia and five individuals with semantic dementia and their respective control groups conducted a sentence completion task. Three tenses were tested: past perfective, past imperfective and present. All tenses had to be produced with three different verb classes, which differed with respect to syntactic and semantic properties: unergative, unaccusative and transitive verbs. The findings imply problems with marking aspect and an interaction between inflection and lexical aspect but no effect of morphological complexity or across the board difficulties with reference to the past in aphasia. Moreover, the results suggest problems with inflection in semantic dementia, an interaction between inflection and lexical aspect and a selective difficulty with imperfective tenses. The study contributes to a better understanding of inflection problems in apha...

Can you distinguish the taste of a red wine versus a rosé? How about the look of a 1960s muscle car versus a foreign import? Do you prefer to grow lilies or tulips? Would you rather listen to Dark Side of the Moon or “Fly Me to the Moon”? To answer any of these questions, you need to use your semantic memory. Your semantic memory is your store of factual knowledge of the world and the meaning of words. It’s how you know that a fork is for eating (not twirling your hair) and what color a lion is. It’s both the source of your vocabulary and how you know what something does even if you don&rsquo...

CONCLUSIONS &IMPLICATIONS: This survey highlights the range of current PPA assessment and intervention practices in use by the respondents. Communication partner training is commonly used by the surveyed SLTs, despite the lack of research evidence examining its effectiveness for PPA. There is a need to develop evidence-based care pathways for people with PPA in order to advocate for further commissioning of clinical services. PMID: 31364253 [PubMed - as supplied by publisher]

Self-report pain scales are the most common way to assess pain in stroke patients with aphasia. The use of self-report pain scales in patients with aphasia is challenging due to communication or cognitive problems. A feasible, reliable and valid instrument to assess pain in patients with aphasia is yet not available. The aim of this study is to examine the reliability and validity of the Pain Assessment Checklist for Seniors with Severe Dementia-Dutch version (PACSLAC-D) in stroke patients with and without aphasia.

The objective of our study was to investigate the extent to which subjective cognitive complaints predicted community reintegration following a stroke, and whether this relationship would be mediated by emotional status. Methods Using a cross-sectional design, patients with a primary diagnosis of stroke (n = 102; age range 25-89 years) were recruited from the register of a neurological rehabilitation service if they were at least 6 months post-stroke and had been discharged home following the stroke. Exclusions included history of dementia, co-morbid psychiatric or neurological disorder, or significant ...

(University of Arizona) People with primary progressive aphasia, a rare dementia that initially attacks the language center of the brain, recruit other areas of the brain to decipher sentences. People who have had strokes or injuries to the brain have been shown to enlist intact brain regions to accomplish tasks. The new study is one of the first to show that people with a neurodegenerative disease can call upon intact areas of the brain for help.

A work of art is a form of language. Paint strokes, paper, shapes, colors and materials come together to form meaningful visual moments. Communication consists of the same basic principle. Sounds don’t have much power on their own, but when coherently strung together, they create meaningful human interaction. For this reason, I find using art in my speech-language sessions a natural fit for working with my students. I always loved how my college professors described the profession of speech-language pathology as “an art and a science.” As SLPs, we provide evidence-based interventions to motivate our clien...
