Language recovery following stroke.
Conclusions: Significant recovery of language function is possible following a stroke, but prediction of level of recovery in an individual patient is difficult. Information about initial aphasia severity and the integrity of cognitive domains other than language can help guide the rehabilitation team, as well as manage expectations for recovery.

Word-finding in confrontation naming and picture descriptions produced by individuals with early post-stroke aphasia.
Conclusion: Our findings contribute to a better understanding of the relationship between performance in confrontation naming and in connected speech production in the first days after stroke onset and also suggest that discourse analysis may provide unique, possibly more complex information.

The Oxford Cognitive Screen (OCS): Validation of a stroke-specific short cognitive screening tool.
This article presents the normative data in a large sample of 140 neurologically healthy participants, a report on incidences of impairments in a sample of 208 acute stroke patients (within 3 weeks of stroke onset), measures of test–retest reliability on an alternate form and convergent and divergent validity. In addition, the full test materials are made freely available for clinical use. (PsycINFO Database Record (c) 2015 APA, all rights reserved)

Clinical Utility of the Neuropsychological Assessment Battery (NAB) after Unilateral Stroke.
Abstract The NAB is a comprehensive battery assessing five cognitive domains (Attention, Language, Memory, Spatial, Executive Function). Despite the advantage of co-normative domain data, its clinical utility is not well established because few studies have reported full-battery findings. The aim of this study was to determine if the NAB was sensitive to well documented hemispheric differences in language and spatial skills after unilateral stroke. We compared demographically matched control participants (n = 52) and individuals after left (LHD, n = 36) or right (RHD, n = 33) hemisphere damage due to stroke on the...

Distinct mechanisms and timing of language recovery after stroke.
Abstract The "language network" is remarkably stable across language tasks but changes in response to injury to specific components or in response to "disconnection" of input to one component. We investigated network changes during language recovery, hypothesizing that language recovery takes place through distinct mechanisms: (a) reperfusion; (b) recovery from diaschisis; (c) recovery from structural disconnection; and (d) "reorganization" of language, whereby various components assume function of a damaged component. We also tested the hypothesis that "reorganization" depends on: the language task, level of perf...

Transcranial electrical stimulation in post-stroke cognitive rehabilitation: Where we are and where we are going.
Cognitive rehabilitation is an important area of neurological rehabilitation, which aims at the treatment of cognitive disorders due to acquired brain damage of different etiology, including stroke. Although the importance of cognitive rehabilitation for stroke survivors is well recognized, available cognitive treatments for neuropsychological disorders, such as spatial neglect, hemianopia, apraxia, and working memory, are overall still unsatisfactory. The growing body of evidence supporting the potential of the transcranial Electrical Stimulation (tES) as tool for interacting with neuroplasticity in the human brain, in tu...

Non-fluent speech following stroke is caused by impaired efference copy.
This study examined the best mechanistic predictors of non-fluent speech among 88 stroke survivors. Objective speech fluency measures were subjected to a principal component analysis (PCA). The primary PCA factor was then entered into a multiple stepwise linear regression analysis as the dependent variable, with a set of independent mechanistic variables. Participants' ability to mimic audio-visual speech ("speech entrainment response") was the best independent predictor of non-fluent speech. We suggest that this "speech entrainment" factor reflects integrity of internal monitoring (i.e., efference copy) of speech producti...

Further Evidence of the Positive Influence of Repetitive Transcranial Magnetic Stimulation on Speech and Language in Patients with Aphasia after Stroke: Results from a Double-Blind Intervention with Sham Condition
Conclusions: Among patients with SRA, compared to a sham condition, adjuvant rTMS improved speech and language skills. The present results add to the accumulating evidence that rTMS as a neuromodulation technique has the capacity to enhance the effect of conventional SLT.Neuropsychobiology

Transcranial direct current stimulation as a novel method for enhancing aphasia treatment effects.
Neuromodulation is an exciting area of development. Currently, there is significant interest in academia, industry, and clinical practice where an effective and acceptable transcranial direct current stimulation (tDCS) kit for use in clinical rehabilitation would offer much benefit to patients’ treatment. In this review, I discuss the latest group studies investigating current tDCS methods for enhancing aphasia treatment effects in post-stroke (sub-acute and chronic) and primary progressive aphasia (PPA) patient populations. This field is still new, and many more investigations with larger samples of patients are needed....

Validation of and Normative Data of the DVAQ-30, a New Video-Naming Test for Assessing Verb Anomia
CONCLUSIONS: The DVAQ-30 fills an important gap and has the potential to help clinicians and researchers better detect verb anomia associated with pathological aging and post-stroke aphasia.PMID:35901465 | DOI:10.1093/arclin/acac052

Transcranial Direct Current Stimulation improves word production in Conduction Aphasia: Electroencephalographic and behavioral evidences
Publication date: September–December 2014 Source:International Journal of Clinical and Health Psychology, Volume 14, Issue 3 Author(s): Alberto Dominguez , Rosario Socas , Hipolito Marrero , Nieves Leon , Jesus LLabres , Enrique Enriquez A Conduction Aphasic patient, RH, with many difficulties at the level of phonological output, was subjected to Transcranial Direct Current Stimulation (tDCS) therapy six months after suffering a stroke. Fifteen daily sessions were administered (five days per week). The treatment led to a better intra-hemispheric electrical coherence and inter-hemispheric balance, as shown by the quanti...

The multiple validities of neuropsychological assessment.
This article discusses construct and criterion validity of neuropsychological tests, as well as assessment validity, which allows determination of whether an individual examinee is producing valid test results. Factor analyses identify 6 domains of abilities. Tests of learning and memory and processing speed are most sensitive to presence of brain dysfunction in both traumatic brain injury (TBI) and Alzheimer’s disease (AD). Tests of processing speed, working memory, verbal symbolic functions, and visuoperceptual and visuospatial judgment and problem solving are sensitive to the severity of TBI and AD, as well as to the ...

Metacognitive deficits in categorization tasks in a population with impaired inner speech.
This study examines the relation of language use to a person's ability to perform categorization tasks and to assess their own abilities in those categorization tasks. A silent rhyming task was used to confirm that a group of people with post-stroke aphasia (PWA) had corresponding covert language production (or "inner speech") impairments. The performance of the PWA was then compared to that of age- and education-matched healthy controls on three kinds of categorization tasks and on metacognitive self-assessments of their performance on those tasks. The PWA showed no deficits in their ability to categorize objects for any ...

A cognitive psychometric model for assessment of picture naming abilities in aphasia.
We present the results of 4 experiments testing our interpretation of the model’s parameters, as they apply to picture naming predictions, lexical properties of the items, statistical properties of the lexicon, and participants’ scores on other tests. We also created a website for researchers and clinicians to analyze item-level data using our model, providing estimates of latent abilities and percentile scores, as well as credible intervals to help gauge the reliability of the estimated model parameters and identify meaningful changes. To the extent that the model is successful, the estimated parameter values may aid ...
