Abstract
Understanding the neurobiology of semantic knowledge is a major goal of cognitive neuroscience. Taxonomic and thematic semantic knowledge are represented differently within the brain's conceptual networks, but the specific neural mechanisms remain unclear. Some neurobiological models propose that the anterior temporal lobe is an important hub for taxonomic knowledge, whereas the TPJ is especially involved in the representation of thematic knowledge. However, recent studies have provided divergent evidence. In this context, we investigated the neural correlates of taxonomic and thematic confrontation naming errors in 79 people with aphasia. We used three complementary lesion-symptom mapping (LSM) methods to investigate how structure and function in both spared and impaired brain regions relate to taxonomic and thematic naming errors. Voxel-based LSM mapped brain damage, activation-based LSM mapped BOLD signal in surviving tissue, and network-based LSM mapped white matter subnetwork integrity to error type. Voxel- and network-based lesion symptom mapping provided converging evidence that damage/disruption of the left mid-to-anterior temporal lobe was associated with a greater proportion of thematic naming errors. Activation-based lesion symptom mapping revealed that higher BOLD signal in the left anterior temporal lobe during an in-house naming task was associated with a greater proportion of taxonomic errors on the Philadelphia Naming Test administered outside of the scanner. A lower BOLD signal in the bilateral angular gyrus, precuneus, and right inferior frontal cortex was associated with a greater proportion of taxonomic errors. These findings provide novel evidence that damage to the anterior temporal lobe is especially related to thematic naming errors.

Abstract
PURPOSE Adults with acquired communication disorders are particularly vulnerable to potential negative effects from the changes that arose during the COVID-19 pandemic. In this longitudinal study, we asked: How did the self-perceived impacts of the pandemic on adults with acquired communication disorders change over time? METHOD We developed an online survey to investigate changes in day-to-day behaviours, psychosocial elements, and communication abilities among members of a community-based stroke recovery centre in the USA. Participants included adults with aphasia or other cognitive-communication disorder from stroke or brain injury. We compared survey responses from summer 2020 (n = 50) and summer 2021 (n = 24) using a concurrent mixed methods design. RESULT The impacts of the pandemic changed over time. By 2021, participants reported a more "normal" amount of time spent on in-person socialising and healthcare, improved quality of life and connectedness to others, and an improvement in overall communication ability. Across both years, participants shared comments regarding changes in routine, increased use of technology, and the positive benefit of therapy groups. CONCLUSION Self-perceived psychosocial elements and communication abilities among stroke and other brain injury survivors changed over the course of the pandemic. Clinicians and researchers should continue providing this population with support and opportunities for engagement.

Abstract
PURPOSE Aphasia is an acquired language impairment that commonly results from stroke. Non-invasive brain stimulation (NIBS) might accelerate aphasia recovery trajectories and has seen mounting popularity in recent aphasia rehabilitation research. The present review aimed to: (1) summarise all existing literature on NIBS as a post-stroke aphasia treatment; and (2) provide recommendations for future NIBS-aphasia research. MATERIALS AND METHODS Databases for published and grey literature were searched using scoping review methodology. 278 journal articles, conference abstracts/posters, and books, and 38 items of grey literature, were included for analysis. RESULTS Quantitative analysis revealed that ipsilesional anodal transcranial direct current stimulation and contralesional 1-Hz repetitive transcranial magnetic stimulation were the most widely used forms of NIBS, while qualitative analysis identified four key themes including: the roles of the hemispheres in aphasia recovery and their relationship with NIBS; heterogeneity of individuals but homogeneity of subpopulations; individualisation of stimulation parameters; and much remains under-explored in the NIBS-aphasia literature. CONCLUSIONS Taken together, these results highlighted systemic challenges across the field such as small sample sizes, inter-individual variability, lack of protocol optimisation/standardisation, and inadequate focus on aphasiology. Four key recommendations are outlined herein to guide future research and refine NIBS methods for post-stroke aphasia treatment.

Abstract
A stroke can disrupt the finely tuned language network resulting in aphasia, a language impairment. Though many stroke survivors with aphasia recover within the first 6 months, a significant proportion have lasting deficits. The factors contributing to optimal treatment response remain unclear. Some evidence suggests that increased modularity or fragmentation of brain networks may underlie post-stroke aphasia severity and the extent of recovery. We examined associations between network organization and aphasia recovery in sixteen chronic stroke survivors with non-fluent aphasia following 35 h of Multi-Modality Aphasia Therapy over 10 days and 20 healthy controls who underwent imaging at a single timepoint. Using diffusion-weighted scans obtained before and after treatment, we constructed whole-brain structural connectomes representing the number of probabilistic streamlines between brain regions. Graph theory metrics were quantified for each connectome using the Brain Connectivity Toolbox. Correlations were examined between graph metrics and speech performance measured using the Boston Naming Test (BNT) at pre-, post- and 3-months post-intervention. Compared to controls, participants with stroke demonstrated higher whole-brain modularity at pre-treatment. Modularity did not differ between pre- and post-treatment. In individuals who responded to therapy, higher pre-treatment modularity was associated with worse performance on the BNT. Moreover, higher pre-treatment participation coefficients (i.e., how well a region is connected outside its own module) for the left IFG, planum temporale, and posterior temporal gyri were associated with greater improvements at post-treatment. These results suggest that pre-treatment network topology may impact therapeutic gains, highlighting the influence of network organization on post-stroke aphasia recovery.

Abstract
Neurobehavioral studies have provided evidence for the effectiveness of anodal tDCS on language production, by stimulation of the left Inferior Frontal Gyrus (IFG) or of left Temporo-Parietal Junction (TPJ). However, tDCS is currently not used in clinical practice outside of trials, because behavioral effects have been inconsistent and underlying neural effects unclear. Here, we propose to elucidate the neural correlates of verb and noun learning and to determine if they can be modulated with anodal high-definition (HD) tDCS stimulation. Thirty-six neurotypical participants were randomly allocated to anodal HD-tDCS over either the left IFG, the left TPJ, or sham stimulation. On day one, participants performed a naming task (pre-test). On day two, participants underwent a new-word learning task with rare nouns and verbs concurrently to HD-tDCS for 20 min. The third day consisted of a post-test of naming performance. EEG was recorded at rest and during naming on each day. Verb learning was significantly facilitated by left IFG stimulation. HD-tDCS over the left IFG enhanced functional connectivity between the left IFG and TPJ and this correlated with improved learning. HD-tDCS over the left TPJ enabled stronger local activation of the stimulated area (as indexed by greater alpha and beta-band power decrease) during naming, but this did not translate into better learning. Thus, tDCS can induce local activation or modulation of network interactions. Only the enhancement of network interactions, but not the increase in local activation, leads to robust improvement of word learning. This emphasizes the need to develop new neuromodulation methods influencing network interactions. Our study suggests that this may be achieved through behavioral activation of one area and concomitant activation of another area with HD-tDCS.

Abstract
BACKGROUND The prediction of post-stroke language function is essential for the development of individualized treatment plans based on the personal recovery potential of aphasic stroke patients. OBJECTIVE To establish a framework for integrating information on connectivity disruption of the language network based on routinely collected clinical magnetic resonance (MR) images into Random Forest modeling to predict post-stroke language function. METHODS Language function was assessed in 76 stroke patients from the Non-Invasive Repeated Therapeutic Stimulation for Aphasia Recovery trial, using the Token Test (TT), Boston Naming Test (BNT), and Semantic Verbal Fluency (sVF) Test as primary outcome measures. Individual infarct masks were superimposed onto a diffusion tensor imaging tractogram reference set to calculate Change in Connectivity scores of language-relevant gray matter regions as estimates of structural connectivity disruption. Multivariable Random Forest models were derived to predict language function. RESULTS Random Forest models explained moderate to high amount of variance at baseline and follow-up for the TT (62.7% and 76.2%), BNT (47.0% and 84.3%), and sVF (52.2% and 61.1%). Initial language function and non-verbal cognitive ability were the most important variables to predict language function. Connectivity disruption explained additional variance, resulting in a prediction error increase of up to 12.8% with variable omission. Left middle temporal gyrus (12.8%) and supramarginal gyrus (9.8%) were identified as among the most important network nodes. CONCLUSION Connectivity disruption of the language network adds predictive value beyond lesion volume, initial language function, and non-verbal cognitive ability. Obtaining information on connectivity disruption based on routine clinical MR images constitutes a significant advancement toward practical clinical application.

Abstract
BACKGROUND Communication disabilities, such as primary progressive aphasia (PPA), impact family members as well as the individuals with the condition. To provide adequate communication care to people with PPA (PwPPA) and their family members, it is crucial to understand the communication needs from the family members' perspectives. To date, research on the communication needs of people with primary progressive aphasia and their family members from the perspectives of family members has been limited. AIMS The specific research objectives were to explore (a) the communication needs pertaining to PwPPA in the early, middle and late stages; and (b) the communication needs pertaining to family members of PwPPA in the early, middle and late stages, from the perspectives of family members. METHODS & PROCEDURES This study employed a qualitative description approach, underpinned by the pragmatic paradigm. Data collection involved semi-structured qualitative interviews with eight family members (relatives of four individuals with the logopenic variant of PPA, of two individuals with the nonfluent variant of PPA, of one individual with the semantic variant of PPA and of one individual with mixed PPA). Qualitative content analysis was used to identify codes and categories in relation to the research objectives. OUTCOMES & RESULTS Qualitative content analysis revealed eight categories of communication needs pertaining to the PwPPA: person-specific needs; diagnosis and disclosure; general communication difficulties; impact on communication in everyday life; impact on cognition; impact on psychosocial well-being; impact on person's dignity and autonomy; and future planning. Six categories were identified pertaining to the family members: information about and awareness of PPA; impact of communication difficulties on family/others; increased responsibilities for the family in everyday life; impact on psychosocial well-being; and future planning. CONCLUSIONS & IMPLICATIONS This investigation has expanded our knowledge in the area by providing insights about communication needs which speech-language pathologists and other health professionals should be aware of and take into account when providing communication care to PwPPA and their families. WHAT THIS PAPER ADDS What is already known on the subject Person- and family-centred communication care is optimally guided by the person's and family's needs and values. Research on communication care for people with primary progressive aphasia has underscored the inclusion of family members. Previous research has investigated the impact and experiences of living with primary progressive aphasia from the family member perspective. What this paper adds to existing knowledge To date, research focusing on identifying the communication needs of people with primary progressive aphasia and their family members from the perspective of family members is limited. This study adds the family members' perspectives on the communication needs pertaining to themselves and their relatives with primary progressive aphasia in the early, middle and late stages of primary progressive aphasia. What are the potential or clinical implications of this work? Several clinical implications have been raised. Family members experience communication needs for themselves and should be included as recipients of communication care. Clinicians supporting people with primary progressive aphasia should be cognizant of the impact of communication fatigue on everyday life and therapy tasks. Communication care for this population should include communication partner training, support for psychosocial well-being and support with communication around future planning.

Abstract
Discourse is a fundamentally important aspect of communication, and discourse production provides a wealth of information about linguistic ability. Aphasia commonly affects, in multiple ways, the ability to produce discourse. Comprehensive aphasia assessments such as the Western Aphasia Battery-Revised (WAB-R) are time- and resource-intensive. We examined whether discourse measures can be used to estimate WAB-R Aphasia Quotient (AQ), and whether this can serve as an ecologically valid, less resource-intensive measure. We used features extracted from discourse tasks using three AphasiaBank prompts involving expositional (picture description), story narrative, and procedural discourse. These features were used to train a machine learning model to predict the WAB-R AQ. We also compared and supplemented the model with lesion location information from structural neuroimaging. We found that discourse-based models could estimate AQ well, and that they outperformed models based on lesion features. Addition of lesion features to the discourse features did not improve the performance of the discourse model substantially. Inspection of the most informative discourse features revealed that different prompt types taxed different aspects of language. These findings suggest that discourse can be used to estimate aphasia severity, and provide insight into the linguistic content elicited by different types of discourse prompts.

Abstract
Importance Motor aphasia is common among patients with stroke. Acupuncture is recommended as an alternative therapy for poststroke aphasia, but its efficacy remains uncertain. Objective To investigate the effects of acupuncture on language function, neurological function, and quality of life in patients with poststroke motor aphasia. Design, Setting, and Participants This multicenter, sham-controlled, randomized clinical trial was conducted in 3 tertiary hospitals in China from October 21, 2019, to November 13, 2021. Adult patients with poststroke motor aphasia were enrolled. Data analysis was performed from February to April 2023. Interventions Eligible participants were randomly allocated (1:1) to manual acupuncture (MA) or sham acupuncture (SA) groups. Both groups underwent language training and conventional treatments. Main Outcomes and Measures The primary outcomes were the aphasia quotient (AQ) of the Western Aphasia Battery (WAB) and scores on the Chinese Functional Communication Profile (CFCP) at 6 weeks. Secondary outcomes included WAB subitems, Boston Diagnostic Aphasia Examination, National Institutes of Health Stroke Scale, Stroke-Specific Quality of Life Scale, Stroke and Aphasia Quality of Life Scale-39, and Health Scale of Traditional Chinese Medicine scores at 6 weeks and 6 months after onset. All statistical analyses were performed according to the intention-to-treat principle. Results Among 252 randomized patients (198 men [78.6%]; mean [SD] age, 60.7 [7.5] years), 231 were included in the modified intention-to-treat analysis (115 in the MA group and 116 in the SA group). Compared with the SA group, the MA group had significant increases in AQ (difference, 7.99 points; 95% CI, 3.42-12.55 points; P = .001) and CFCP (difference, 23.51 points; 95% CI, 11.10-35.93 points; P < .001) scores at week 6 and showed significant improvements in AQ (difference, 10.34; 95% CI, 5.75-14.93; P < .001) and CFCP (difference, 27.43; 95% CI, 14.75-40.10; P < .001) scores at the end of follow-up. Conclusions and Relevance In this randomized clinical trial, patients with poststroke motor aphasia who received 6 weeks of MA compared with those who received SA demonstrated statistically significant improvements in language function, quality of life, and neurological impairment from week 6 of treatment to the end of follow-up at 6 months after onset. Trial Registration Chinese Clinical Trial Registry: ChiCTR1900026740.

Abstract
BACKGROUND Aphasia is a communication disorder that affects the ability to process and produce language, which severely impacting their lives. Computer-aid exercise rehabilitation has shown to be highly effective for these patients. OBJECTIVE In our study, we proposed a speech rehabilitation system with mirrored therapy. The study goal is to construct a effective rehabilitation software for aphasia patients. METHODS This system collects patients' facial photos for mirrored video generation and speech synthesis. The visual feedback provided by the mirror creates an engaging and motivating experience for patients. And the evaluation platform employs machine learning technologies for assessing speech similarity. RESULTS The sophisticated task-oriented rehabilitation training with mirror therapy is also presented for experiments performing. The performance of three tasks reaches the average scores of 83.9% for vowel exercises, 74.3% for word exercies and 77.8% for sentence training in real time. CONCLUSIONS The user-friendly application system allows patients to carry out daily training tasks instructed by the therapists or the prompt information of menu. Our work demonstrated a promising intelligent mirror software system for reading-based aphasia rehabilitation.

Abstract
Aphasia leads to disability, which, in turn, limits and can result in a complete breakdown of roles and social bonds. Thus, the aim of this study was to assess the impact of aphasia disorders on the quality of life of patients after an ischemic stroke. A prospective study among 116 patients with an ischemic stroke (the study group: 68 participants, 38.25% female, included patients with aphasia after a stroke; the control group: 48 patients, 37.5% female, without aphasia) was conducted at the Neurological Department of the Provincial Specialist Hospital in Włocławek. The patients were assessed twice: the first assessment was conducted during hospitalization using the Aphasia Dynamics Assessment Scale and the Aphasia Test Method of Jadwiga Szumska, and the second assessment of the quality of life after six months was conducted using the WHOQOL-BREF questionnaire. The patients from the control group rated their overall quality of life more highly than the patients from the study group. Statistically significant differences were observed in the physical domain, the psychological domain, and the environmental domain. The analysis of sociodemographic factors indicated a negative impact on the quality of life of the following variables: female gender, 55-64 years of age, vocational education, and place of residence-rural area. The degree and type of aphasia influenced the overall quality of life. Studies with larger samples are necessary.

Disabil Rehabil Assist Technol 2023; 18:1473-1488. [PMID: 35166636 DOI: 10.1080/17483107.2022.2037758] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Accepted: 01/28/2022] [Indexed: 10/19/2022]
Abstract
BACKGROUND Aphasia is a debilitating acquired language disorder that often persists as a chronic condition. However, long-term support options are scarce, necessitating the consideration of alternative approaches. Chronic condition self-management approaches, which aim to build self-efficacy and empower people to take responsibility for the day-to-day management of their health condition, may benefit people with aphasia (PwA). Technology is widely used in chronic condition self-management and investigation is required to determine whether it could play a role in aphasia self-management. OBJECTIVE This study aimed to explore speech-language pathologist (SLP) perspectives on the potential use of technology to support aphasia self-management. METHODS A qualitative study was conducted with 15 SLPs using semi-structured interviews. Qualitative content analysis was applied to verbatim transcripts to identify codes, categories, and sub-themes which were developed into themes. RESULTS Three themes were identified: (1) technology supports holistic aphasia self-management by providing additional avenues for service delivery, overall communication, and learning opportunities thus enhancing independence and life participation; (2) SLP and communication partner (CP) assistance can support PwA to use technology for aphasia self-management; (3) considerations and potential barriers to PwA use of technology for aphasia self-management. CONCLUSIONS Technology can support aphasia self-management by expanding service delivery options, allowing for increased frequency and intensity of therapy practise, and facilitating communication and participation. Personal, professional, and organizational barriers should be addressed in the development of technology-enabled aphasia self-management approaches. SLPs and CPs can offer PwA assistance with technology but may themselves need additional support. Solutions for identified barriers should be considered, such as providing training in the use of technology and implementing aphasia-friendly modifications.IMPLICATIONS FOR REHABILITATIONSelf-management approaches are being explored in the area of aphasia management as a means of offering a holistic, sustainable intervention option that meets the long-term needs of people with aphasia.A range of technology-based resources are currently used in chronic condition self-management and in aphasia therapy, and there are many possibilities for the use of technology in aphasia self-management approaches.Speech-language pathologists identified that technology could facilitate aphasia self-management by expanding service delivery options (e.g., real-time and asynchronous telepractice), enabling increased frequency and intensity of therapy through providing a means of independent practise, offering options for augmentative alternative communication, and enhancing life participation by supporting social communication and daily tasks.,Speech-language pathologists are interested in using technology for aphasia self-management; however, barriers related to organizational policies, individual experience and confidence using technology, and technology itself must be addressed.

Abstract
In recent years, there has been a rapid increase in the number of people with aphasia due to brain lesions worldwide, which has prompted researchers to carry out in-depth studies on the pathogenesis, inducement and prognosis of aphasia from neurology, clinical medicine, psychology and other disciplines. With the deepening of research and understanding of aphasia, it is generally believed that a single discipline can no longer meet the needs of the academic community. Therefore, multidisciplinary integration has emerged and achieved fruitful results. This paper, based on the biblioshiny package run by R, conducts bibliometric analysis on the international interdisciplinary research status of conversation and aphasia, predicts its future development direction, and provides reference for relevant domestic research from international source journals. The results indicate that led by Australia, the United Kingdom, the United States and other countries, the international conversational aphasia research has formed a complete system, and formed a "descriptive study of patients with language disorders" and "applied study of rehabilitation treatment". In the future, while continuing to focus on these two categories of research, the empathy ability of conversational partners and medical staff may be taken into account, in order to better contribute to improving patients' quality of life.

Bilateral Transfer of Performance between Real and Non-Immersive Virtual Environments in Post-Stroke Individuals: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:3301. [PMID: 36834000 PMCID: PMC9963577 DOI: 10.3390/ijerph20043301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 02/07/2023] [Accepted: 02/10/2023] [Indexed: 06/18/2023]
Abstract
(1) Background: Post-stroke presents motor function deficits, and one interesting possibility for practicing skills is the concept of bilateral transfer. Additionally, there is evidence that the use of virtual reality is beneficial in improving upper limb function. We aimed to evaluate the transfer of motor performance of post-stroke and control groups in two different environments (real and virtual), as well as bilateral transfer, by changing the practice between paretic and non-paretic upper limbs. (2) Methods: We used a coincident timing task with a virtual (Kinect) or a real device (touch screen) in post-stroke and control groups; both groups practiced with bilateral transference. (3) Results: Were included 136 participants, 82 post-stroke and 54 controls. The control group presented better performance during most parts of the protocol; however, it was more evident when compared with the post-stroke paretic upper limb. We found bilateral transference mainly in Practice 2, with the paretic upper limb using the real interface method (touch screen), but only after Practice 1 with the virtual interface (Kinect), using the non-paretic upper limb. (4) Conclusions: The task with the greatest motor and cognitive demand (virtual-Kinect) provided transfer into the real interface, and bilateral transfer was observed in individuals post-stroke. However, this is more strongly observed when the virtual task was performed using the non-paretic upper limb first.

Abstract
PURPOSE A critical review was completed to evaluate replication of aphasia treatments that have been vetted and accepted on the American Speech-Language-Hearing Association Practice Portal. METHOD The electronic databases Academic Search Premier, ProQuest Central, CINAHL Complete, and ERIC were searched for relevant articles using treatment names as keywords. Coders compared stimuli, material, design, and statistical analysis to pilot treatment approaches. Each study was coded as direct, conceptual, failed, or no replication. RESULTS Eighteen treatment approaches were selected for this review. A total of 188 articles met the inclusion criteria. Results revealed that 14 out of 18 treatment approaches were somehow replicated. Direct replications as the most valuable replication type for affirming previously found results were represented in only 1.5% of all studies (3/188). Failed direct replication were at 2% overall (4/188). Conceptual replications were more common across treatment approaches, but also represented at a low level with 22.8% (43/188). The majority of studies were coded as no replication attempt with 73.4%. DISCUSSION A critical factor in developing an evidence-based practice is the existence of replicated results for treatment. Replication evaluates the reproducibility of an author's or authors' research methodology and resulting outcomes and helps to ensure that observed treatment effects are reproducible. For an evidence-based treatment to be implemented or used in any clinical setting, it must be one that can be replicated. Direct and conceptual replications of aphasia treatment approaches were found to be alarmingly low considering the importance of replication in our field. It is recommended that replication should become more valued and mainstreamed in aphasia research. A replication database that compiles and maintains treatment manuals for replication purposes can increase the accessibility and acceptability of replications for researchers.

Abstract
Background Although speech-language therapy (SLT) is proven to be beneficial to recovery of post-stroke aphasia, delivering sufficiently high amounts of dosage remains a problem in real-world clinical practice. Self-managed SLT was introduced to solve the problem. Previous research showed in a 10-week period, increased dosage frequency could lead to better performance, however, it is uncertain if dosage still affects performance over a longer period of practice time and whether gains can be seen following practice over several months. Objective This study aims to evaluate data from a health app (Constant Therapy) to investigate the relationship between dosage amount and improvements following a 30-week treatment period. Two cohorts of users were analyzed. One was comprised of patients with a consistent average weekly dosage amount and the other cohort was comprised of users whose practice had higher variability. Methods We conducted two analyses with two cohorts of post-stroke patients who used Constant Therapy. The first cohort contains 537 "consistent" users, while the second cohort contains 2,159. The 30-week practice period was split into three consecutive 10-week practice windows to calculate average dosage amount. In each 10-week practice period, patients were grouped by their average dosage into low (0-15 min/week), medium (15-40 min/week) and moderate dosage (greater than 40 min/week) groups. Linear mixed-effects models were employed to evaluate if dosage amount was a significant factor affecting performance. Pairwise comparison was also applied to evaluate the slope difference between groups. Results For the consistent cohort, medium (β = .002, t 17,700 = 7.64, P < .001) and moderate (β = .003, t 9,297 = 7.94, P < .001) dosage groups showed significant improvement compared to the low dosage group. The moderate group also showed greater improvement compared to the medium group. For the variable cohort in analysis 2, the same trend was shown in the first two 10-week windows, however, in weeks 21-30, the difference was insignificant between low and medium groups (β = .001, t = 1.76, P = .078). Conclusions This study showed a higher dosage amount is related to greater therapy outcomes in over 6 months of digital self-managed therapy. It also showed that regardless of the exact pattern of practice, self-managed SLT leads to significant and sustained performance gains.

Abstract
Stroke is a prevalent neurologic condition that portends a high risk of morbidity and mortality such that patients impacted by stroke and their caregivers can benefit from palliative care at the time of diagnosis and throughout the disease trajectory. Clinicians who care for stroke patients should be adept at establishing rapport with patients and caregivers, delivering serious news, responding to emotions, discussing prognosis, and establishing goals of care efficiently in an acute stroke setting. Aggressive stroke care can be integrated with a palliative approach to care that involves aligning the available treatment options with a patient's values and goals of care. Reassessing the goals throughout the hospitalization provides an opportunity for continued shared decision-making about the intensity of poststroke interventions. The palliative needs for stroke patients may increase over time depending on the severity of disease, poststroke complications, stroke-related symptoms, and treatment intensity preferences. If the decision is made to transition the focus of care to comfort, the support of an interdisciplinary palliative care or hospice team can be beneficial to the patient, family members, and surrogate decision makers.

Abstract
PURPOSE In the aphasia literature, motivation has been described as potentially influencing rehabilitation outcomes, and there are reports that researchers and clinicians have acted to promote it. However, studies directly investigating the range of beliefs and practices surrounding motivation do not exist currently. The purpose of this scoping review is to develop themes related to the beliefs and practices appearing in the recent aphasia literature. METHOD Four databases (CINAHL, PsycINFO, PubMed, and Google Scholar) were searched using keywords aphasia and motivation (including derivatives such as motiv*) for articles published between 2009 and 2020. Searches returned 19,731 articles; after deleting duplicates and applying inclusionary criteria, 365 articles remained. In each article, text surrounding the term motivation was highlighted and thematic analysis was applied to these quotations. RESULTS Sixteen themes were developed through thematic analysis and placed into two groups. The first group contained five themes suggesting that researchers believed that motivation should be studied and recognized the value of motivation in person(s) with aphasia when participating in research or clinical activities. The second group contained 11 themes reporting diverse beliefs and practices in how motivation is incorporated in research and clinical activities. CONCLUSIONS Results from this scoping review suggest that aphasia researchers, clinicians, and persons with aphasia hold beliefs about motivation that can influence clinical and research decisions. In general, beliefs and decisions related to motivation appeared to be guided by intuition rather than theories of motivation. These themes are discussed within the context of three psychological needs proposed by self-determination theory: competency, autonomy, and relatedness. Applying theories of motivation to future study in aphasia rehabilitation will guide work that can provide empirical support for these beliefs.

Abstract
The impact of aphasia on the everyday life of Greek-speaking people with aphasia (PWA) is often underestimated by rehabilitation clinicians. This study explores the adaptation and psychometric properties of the Greek (GR) version of The Aphasia Impact Questionnaire-21 (AIQ-21-GR) to address this issue. The aim of this study is to determine the reliability and validity of the Greek version of the AIQ-21. The AIQ-21-GR was administered to 69 stroke survivors, 47 with aphasia and 22 without aphasia. The data were analyzed to determine reliability and validity. Content validity was based on the Consensus-based Standards for the selection of health Measurement Instruments guidelines. The AIQ-21-GR shows high levels of reliability and validity. The results confirmed high scores of internal consistency (Cronbach’s α = 0.91) and indicated good known—groups validity (Mann–Whitney U = 202, p < 001). Content validity achieved high scores with an overall median score of 4 [Q25 = 4, Q75 = 5]. The psychometric properties of the AIQ-21-GR support the reliability and validity of the tool for investigating the impact of aphasia on the quality of life of Greek-speaking PWA. The AIQ-21-GR can be used for setting functional goals in collaboration with PWA and as a patient reported outcome measure for functional communication training.

Abstract
OBJECTIVE To evaluate the existing randomized controlled trials (RCTs) for evidence of the efficacy and safety of head acupuncture (HA) plus Schuell's language rehabilitation (SLR) in post-stroke aphasia. METHODS Seven databases including Embase, PubMed, Cochrane Library, Technology Periodical Database, the China National Knowledge Infrastructure, SinoMed and Wanfang Data Information Site were searched for RCTs published from database inception until November 14, 2021. RCTs that compared HA plus SLR with sham (or blank) control, acupuncture therapy alone, certain language rehabilitation therapy alone or other therapies for post-stroke aphasia were included. Data were extracted and assessed, and the quality of RCTs was evaluated. Fixed-effects model was used, with meta-inflfluence analysis, meta-regression, and regression-based sub-group analyses applied for exploration of heterogeneity. Publication bias was estimated by funnel plots and Egger's tests. RESULTS A total of 32 RCTs with 1,968 patients were included and 51 comparisons were conducted classified as types of strokes and aphasia. (1) For patients with aphasia after ischemic stroke, HA plus PSA showed significantly higher accumulative markedly effective rate [relative risk (RR)=1.55, 95% confidence interval (CI): 1.19-2.02, I2=0%] and accumulative effective rate (RR=1.22, 95% CI: 1.09-1.36, I2=0%). (2) For patients with comprehensive types of stroke, HA plus PSA was more effective in increasing recovery rate (RR=1.89, 95% CI: 1.39-2.56, I2=0%), accumulative markedly effective rate (RR=1.53, 95% CI: 1.36-1.72, I2=9%) and accumulative effective rate (RR=1.14, 95% CI: 1.09-1.19, I2=34%). (3) For patients with aphasia after stroke, HA plus PSA was superior to PSA alone with statistical significance in increasing recovery rate (RR=2.08, 95% CI: 1.24-3.46, I2=0%), accumulative markedly effective rate (RR=1.49, 95% CI: 1.24-1.78, I2=0%) and accumulative effective rate (RR=1.15, 95% CI: 1.06-1.24, I2=39%). (4) For patients with multiple types of aphasia, HA plus PSA also demonstrated significantly higher recovery rate (RR=1.86, 95% CI: 1.28-2.72, I2=0%), accumulative markedly effective rate (RR=1.55, 95% CI: 1.35-1.78, I2=22%), and accumulative effective rate (RR=1.17, 95% CI: 1.11-1.23, I2=41%). (5) For patients with motor aphasia after ischemic stroke, compared with PSA alone, HA plus PSA showed significantly higher accumulative markedly effective rate (RR=1.38, 95% CI: 1.06-1.79, I2=0%) and accumulative effective rate (RR=1.20, 95% CI: 1.05-1.37, I2=0%). Meta-regression analyses were performed without significant difference, and publication bias was found in some comparisons. CONCLUSION HA plus SLR was significantly associated with better language ability and higher effective rate for patients with post-stroke aphasia, and HA should be operated cautiously especially during acupuncture at eye and neck.

Abstract
La afasia después de un daño cerebral y sus diferentes condiciones negativas derivadas, afectan a la calidad de vida (CdV) de la persona. El objetivo de este estudio es describir y analizar la literatura de los años comprendidos entre 2016 y 2020 para identificar y cuantificar aspectos relevantes de la CdV y su evaluación en personas con afasia (PWA). Para lo anterior, se consultaron tres bases de datos (PsycINFO, Medline y Psicodoc). Se incluyeron 38 estudios. Se codificaron y analizaron las características de los estudios y se evaluó la calidad de los trabajos siguiendo las pautas marcadas por la STROBE y la NIH. Los resultados muestran que la prueba de evaluación de CdV más utilizada fue la Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39) (n= 19, 50.00%). En la mayoría de los estudios, independientemente de las pruebas de evaluación, las PWA presentan una baja CdV. Los estudios seleccionados presentan una calidad metodológica media-alta. Como conclusión cabe destacar que, además de limitar aspectos de la comunicación y el lenguaje, la afasia afecta negativamente a la CdV de forma global de la persona que la padece. El desarrollo de pruebas de evaluación de la CdV puede ayudar a los profesionales a planificar una intervención adecuada.

J Med Internet Res 2022; 24:e36135. [PMID: 35857353 PMCID: PMC9350823 DOI: 10.2196/36135] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 05/18/2022] [Accepted: 05/30/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Although the efficacy of high-dose speech-language therapy (SLT) for individuals with poststroke aphasia has been established in the literature, there is a gap in translating these research findings to clinical practice. Therefore, patients continue to receive suboptimal amounts of SLT, with negative consequences for their functional communication recovery. Recent research has identified self-managed digital health technology as one way to close the dosage gap by enabling high-intensity therapy unrestricted by clinician availability or other practical constraints. However, there is limited empirical evidence available to rehabilitation professionals to guide dose prescriptions for self-managed SLT despite their increasing use in the COVID-19 era and likely beyond. OBJECTIVE This study aims to leverage real-world mobile health data to investigate the effects of varied dosage frequency on performance outcomes for individuals with poststroke speech, language, and cognitive deficits following a 10-week period of self-managed treatment via a commercially available digital health platform. METHODS Anonymized data from 2249 poststroke survivors who used the Constant Therapy app between late 2016 and 2019 were analyzed. The data included therapy tasks spanning 13 different language and cognitive skill domains. For each patient, the weekly therapy dosage was calculated based on the median number of days per week of app use over the 10-week therapy period, binned into groups of 1, 2, 3, 4, or ≥5 days per week. Linear mixed-effects models were run to examine change in performance over time as a function of dosage group, with post hoc comparisons of slopes to evaluate the performance gain associated with each additional day of practice. RESULTS Across all skill domains, linear mixed-effects model results showed that performance improvement was significantly greater for patients who practiced 2 (β=.001; t15,355=2.37; P=.02), 3 (β=.003; t9738=5.21; P<.001), 4 (β=.005; t9289=7.82; P<.001), or ≥5 (β=.005; t6343=8.14; P<.001) days per week compared with those who only practiced for 1 day per week. Post hoc comparisons confirmed an incremental dosage effect accumulating with each day of practice (ie, 1 day vs 2 days, 2 days vs 3 days, and 3 days vs 4 days), apart from 4 days versus ≥5 days of practice per week. The result of greater improvement for higher versus lower dosage frequency groups was true not only across all domains but also within a majority of individual subdomains. CONCLUSIONS The findings from this study demonstrated that increased dosage frequency is associated with greater therapy gains over a 10-week treatment period of self-managed digital therapy. The use of real-world data maximizes the ecological validity of study results and makes the findings more generalizable to clinical settings. This study represents an important step toward the development of optimal dose recommendations for self-managed SLT.

A Comparative Analysis of Functional Status and Mobility in Stroke Patients with and without Aphasia. J Clin Med 2022; 11:jcm11123478. [PMID: 35743548 PMCID: PMC9225387 DOI: 10.3390/jcm11123478] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 06/04/2022] [Accepted: 06/15/2022] [Indexed: 11/16/2022] Open
Abstract
All researchers agree that aphasia is a serious consequence of a stroke, but they also report contradictory data regarding the functional outcome. The aim of this study was, therefore, to assess the functional outcomes of stroke patients with and without aphasia, who were undertaking a regular rehabilitation programme. MATERIALS AND METHODS The study group consisted of 116 post-stroke patients, including 54 patients without aphasia (G1) and 62 patients with aphasia (G2). The following tests were used before (T1) and after (T2) rehabilitation measurement points: Barthel Index (BI), Sitting Assessment Scale (SAS), Berg Balance Scale (BBS), Trunk Control Test (TCT), Test Up & Go (TUG) and the Timed Walk Test (TWT). RESULTS The group of post-stroke patients with aphasia had a significantly longer time since a stroke on admission, a significantly longer length of stay in the ward and significantly worse SAS and TCT scores at T2, compared to patients without aphasia. Both groups achieved significant improvement in all studied parameters (SAS, TCT, BI, BBS, TUG and TWT). Aphasia was a predictor of functional status in the stroke patients group, but only at the time of admission to the ward. CONCLUSIONS Patients with and without aphasia have an equal likelihood of improving their functional status and returning to independence. Aphasia should not be an absolute factor that excludes stroke patients from research studies on their functional status.

Abstract
In recent years, stakeholders engaged in the study, treatment, and understanding of aphasia outcomes have emphasized the need for greater transparency regarding the economics of aphasia rehabilitation. Most notably, third-party payers and clinicians have a keen interest in understanding the resources used to treat aphasia, particularly the cost-effectiveness and value of aphasia treatments. In this article, we review the current literature related to the economic burden of aphasia and the cost and cost-effectiveness of aphasia treatments. To date, relatively few scholars have attempted to study the efficiency, scale, and scope related to the economics of aphasia and the cost-effectiveness of aphasia treatment. While studies of the cost-effectiveness of aphasia treatments have shown rehabilitative treatments conform to established quality and cost benchmarks, the continued progress and developments in the treatment of aphasia and measurement of clinical outcomes has left many areas unstudied. We highlight the need for greater emphasis on the cost-effectiveness of aphasia treatments in addition to the traditional focus on the efficacy of treatment outcomes.

World J Psychiatry 2022; 12:450-469. [PMID: 35433325 PMCID: PMC8968505 DOI: 10.5498/wjp.v12.i3.450] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 08/13/2021] [Accepted: 02/10/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Neuropsychiatric symptoms (NPS) have been insufficiently examined in persons with aphasia (PWA) because most previous studies exclude participants with language and communication disorders.
AIM To report a two-part study consisting of a literature review and an observational study on NPS in post-stroke aphasia.
METHODS Study 1 reviewed articles obtained from PubMed, PsycINFO, Google Scholar and Cochrane databases after cross-referencing key words of post-stroke aphasia to NPS and disorders. Study 2 examined language deficits and activities of daily living in 20 PWA (median age: 58, range: 28-65 years; 13 men) with the Western Aphasia Battery-Revised and the Barthel Index, respectively. Informants of these 20 PWA were proxy-evaluated with the Neuropsychiatric Inventory and domain-specific scales, including the Stroke Aphasia Depression Questionnaire-10 item version and the Starkstein Apathy Scale. In addition, an adapted version of the Hospital Anxiety and Depression Scale was directly administered to the PWA themselves. This observational study is based on the baseline assessment of an intervention clinical trial (EudraCT: 2017-002858-36; ClinicalTrials.gov identifier: NCT04134416).
RESULTS The literature review revealed a broad spectrum of NPS in PWA, including depression, anxiety, apathy, agitation/aggression, eating and sleep disorders, psychosis, and hypomania/mania. These findings alert to the need for improving assessment and treatment approaches of NPS taking into consideration their frequent occurrence in PWA. Study 2 showed that the 20 participants had mild- to-moderate aphasia severity and were functionally independent. A wide range of comorbid NPS was found in the post-stroke aphasic population (median number of NPS: 5, range: 1-8). The majority of PWA (75%) had depressive symptoms, followed by agitation/aggression (70%), irritability (70%), anxiety (65%) and appetite/eating symptoms (65%). Half of them also presented symptoms of apathy, whereas euphoria and psychotic symptoms were rare (5%). Domain-specific scales revealed that 45% of participants had apathy and 30% were diagnosed with depression and anxiety.
CONCLUSION Concurrent NPS are frequent in the chronic period of post-stroke aphasia. Therefore, further research on reliable and valid assessment tools and treatment for this aphasic population is strongly warranted.

Abstract
This systematic review aimed to determine how aerobic exercise affects cognition after stroke, with particular focus on aphasia and language improvement. Methodological quality was assessed with the PEDro+ scale with half of the 27 included studies rated as high quality. Data extraction focused on cognitive effects of aerobic exercise post-stroke, intervention characteristics, outcome measures, and participant characteristics. Whereas attention, memory, and executive functioning measures were common across the included studies, no study included a language-specific, performance-based measure. Seventeen studies reported positive cognitive effects, most frequently in the domains of attention, memory and executive functioning. Variability in outcome measures, intervention characteristics, and participant characteristics made it difficult to identify similarities among studies reporting positive cognitive effects of exercise or among those studies reporting null outcomes. Only three studies provided specific information about the number of individuals with aphasia included or excluded, who comprise approximately one-third of the stroke population. The review identified patent gaps in our understanding of how aerobic exercise may affect not only the cognitive domain of language post-stroke but also the broader cognitive functioning of individuals with post-stroke aphasia. Methodological limitations of the reviewed studies also warrant further examination of the direct impact of aerobic exercise on cognition post-stroke with careful attention to the selection and reporting of population, intervention, and outcomes.

Abstract
Introduction Obesity is associated with fatigue in many diseases, but the correlation between obesity and poststroke fatigue (PSF) is unclear. The study aimed to investigate the relationship between body mass index (BMI) and the occurrence of and recovery from PSF. Methods Within 3 days of the onset of ischemic stroke, patients were consecutively recruited. We assessed PSF at admission and at 6, 12, and 24 months with the Fatigue Severity Scale (FSS). Multivariable logistic regression and restricted cubic spline function were used to explore the relationships between baseline BMI and the risk of PSF at different time points. The correlation between baseline BMI and the dynamic changes in the natural logarithm transformation of the FSS (lnFSS) score during the follow-up period was analyzed by the piecewise linear mixed-effects model. Results A total of 1026 stroke patients were included. Multivariable analyses indicated that obesity was associated with a decreased risk of early PSF (fatigue diagnosed at baseline) [odds ratio (OR) 0.61, 95% confidence interval (CI) 0.41–0.93] but an increased risk of late PSF (fatigue diagnosed 6 months after the index stroke) (OR 1.63, 95% CI 1.06–2.50 for 6 months; OR 1.87, 95% CI 1.18–2.96 for 12 months; OR 2.11, 95% CI 1.28–3.49 for 24 months). Longitudinal analyses indicated that in the late stage of fatigue, the higher the BMI category, the slower the rate of decrease was for the FSS score. Conclusion Obese patients are less likely to develop fatigue in the acute stage of ischemic stroke. However, they are more prone to late fatigue and exhibit a slower decline in the FSS score in the long term.

Abstract
Purpose The COVID-19 pandemic has led to stay-at-home orders and social distancing guidelines that have the potential to greatly impact individuals' behavior and social engagement. Adults recovering from stroke or other brain trauma, who often have communication difficulties and other long-term challenges, are a population already at risk of isolation and lower quality of life. We investigated the impact of public health guidelines and related behavioral changes on self-perceptions of communication abilities and psychosocial factors in this population. Method The Stroke Comeback Center, a community-based center for stroke and other brain trauma survivors with communication impairments, disseminated an online survey to current members to investigate changes in communication, social engagement, and quality of life. Results Participants (N = 50) reported a number of changes in their day-to-day activities that reflect the current social distancing guidelines, such as reduced outings into the community and fewer in-person conversations with those living outside one's home. Overall, feelings of connectedness to others and overall quality of life were reported to be decreased when compared to before the COVID-19 pandemic, whereas receptive language abilities and technology skills were reported to have improved. Perhaps most interestingly, certain behavioral changes (including healthy movement activities and participation in virtual programs) had specific relationships with perceived communication abilities and social engagement. Conclusions Changes in daily life resulting from the COVID-19 pandemic have had a tangible impact on self-perceived psychosocial elements (e.g., quality of life) and communication abilities among stroke and other brain trauma survivors. Clinicians and researchers may consider these perceived changes when engaging with this population as the effects of the pandemic continue and in the period of community re-entry that may follow.

Abstract
The authors present a unique case of immune-mediated necrotizing myopathy in a 60-year-old female who presented with aphasia, tremor, and progressive muscular weakness. To the best of our knowledge, the presentation of aphasia and tremor has not been previously reported in immune-mediated necrotizing myopathy. This rare presentation may mimic a variety of other central nervous system and myopathic disorders. Delays in prompt diagnosis and treatment of immune-mediated necrotizing myopathy can be detrimental to the physical and mental well-being of the patient and additionally leads to inefficient use of healthcare resources. Therefore, it is beneficial for clinicians to be aware of this symptomatic presentation in order to include immune-mediated necrotizing myopathy as a key differential diagnosis. Awareness of aphasia and tremor as potential symptoms of immune-mediated necrotizing myopathy will improve the quality of patient care.

Abstract
ABSTRACT The current status of the diagnosis and management of poststroke aphasia (PSA) in China is unknown.To analyze the physicians' strategy and knowledge about the management of PSA in clinical practice and the needs for standardization of diagnosis and treatment.This survey was conducted in March-August 2019 at 32 tertiary hospitals in 16 provinces/municipalities in China. The attending physicians from the Neurology and Neuro-rehabilitation/Rehabilitation Departments were included. The online questionnaire inquired about patient information, physicians' diagnosis and treatment behavior for PSA, and physicians' understanding of PSA.A total of 236 physicians completed the survey. Regarding PSA assessment, 99.2% of the physicians reported using medical history and physical examination, 93.2% reported using neuroimaging, and 76.3% reported using dedicated scales. Most physicians used a combination of drug and non-drug treatment. Neuro-regenerators/cerebral activators and anti-dementia drugs were the most common pharmacotherapies; butylphthalide, edaravone, and memantine were most frequently prescribed. Six months poststroke was rendered as a spontaneous language recovery period, and a ≥6-month treatment for PSA was suggested by many physicians. The lack of standardized treatment regimen/clinical guidelines and the limited number of approved drugs for PSA were the primary challenges encountered by physicians during practice. The majority of the physicians agreed with the necessity of guidelines or consensus for the diagnosis and treatment of PSA.The knowledge gaps exist among physicians in China regarding the assessment and management of PSA. The improved awareness of the available guidelines/consensus could improve the performance of the physicians.

Abstract
BACKGROUND Health-related quality of life (HRQL) in stroke survivors is related to numerous factors, but more research is needed to delineate factors related to HRQL in people with aphasia. OBJECTIVE To examine the relationship between HRQL and demographic factors, impairment-based measures, and lesion characteristics in chronic aphasia. METHODS A total of 41 left-hemisphere stroke survivors with aphasia underwent cognitive testing and magnetic resonance imaging. To address relationships with demographic and impairment-based measures, test scores were entered into a principal component analysis (PCA) and multiple linear regression was performed for overall and domain (physical, communication, psychosocial) scores of the Stroke and Aphasia Quality of Life Scale (SAQOL-39g). Independent variables included factor scores from the PCA, motricity, lesion volume, depressed mood, and demographic variables. To address relationships with lesion location, multivariate support vector regression lesion-symptom mapping (SVR-LSM) was used to localize lesions associated with SAQOL-39g scores. RESULTS The PCA yielded 3 factors, which were labeled Language Production, Nonlinguistic Cognition, and Language Comprehension. Multiple linear regression revealed that depression symptoms predicted lower SAQOL-39g average and domain scores. Lower motricity scores predicted lower SAQOL-39g average and physical scores, and lower Language Production factor scores predicted lower communication scores. SVR-LSM demonstrated that basal ganglia lesions were associated with lower physical scores, and inferior frontal lesions were associated with lower psychosocial scores. CONCLUSIONS HRQL in chronic left-hemisphere stroke survivors with aphasia relates to lesion location, depression symptoms, and impairment-based measures. This information may help identify individuals at risk for specific aspects of low HRQL and facilitate targeted interventions to improve well-being.

The Cologne Picture Naming Test for Language Mapping and Monitoring (CoNaT): An Open Set of 100 Black and White Object Drawings. Front Neurol 2021; 12:633068. [PMID: 33746888 PMCID: PMC7966504 DOI: 10.3389/fneur.2021.633068] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 01/12/2021] [Indexed: 01/10/2023] Open
Abstract
Language assessment using a picture naming task crucially relies on the interpretation of the given verbal response by the rater. To avoid misinterpretations, a language-specific and linguistically controlled set of unambiguous, clearly identifiable and common object-word pairs is mandatory. We, here, set out to provide an open-source set of black and white object drawings, particularly suited for language mapping and monitoring, e.g., during awake brain tumour surgery or transcranial magnetic stimulation, in German language. A refined set of 100 black and white drawings was tested in two consecutive runs of randomised picture order and was analysed in respect of correct, prompt, and reliable object recognition and naming in a series of 132 healthy subjects between 18 and 84 years (median 25 years, 64% females) and a clinical pilot cohort of 10 brain tumour patients (median age 47 years, 80% males). The influence of important word- and subject-related factors on task performance and reliability was investigated. Overall, across both healthy subjects and patients, excellent correct object naming rates (97 vs. 96%) as well as high reliability coefficients (Goodman-Kruskal's gamma = 0.95 vs. 0.86) were found. However, the analysis of variance revealed a significant, overall negative effect of low word frequency (p < 0.05) and high age (p < 0.0001) on task performance whereas the effect of a low educational level was only evident for the subgroup of 72 or more years of age (p < 0.05). Moreover, a small learning effect was observed across the two runs of the test (p < 0.001). In summary, this study provides an overall robust and reliable picture naming tool, optimised for the clinical use to map and monitor language functions in patients. However, individual familiarisation before the clinical use remains advisable, especially for subjects that are comparatively prone to spontaneous picture naming errors such as older subjects of low educational level and patients with clinically apparent word finding difficulties.

Extended fMRI-Guided Anodal and Cathodal Transcranial Direct Current Stimulation Targeting Perilesional Areas in Post-Stroke Aphasia: A Pilot Randomized Clinical Trial. Brain Sci 2021; 11:306. [PMID: 33671031 PMCID: PMC7997197 DOI: 10.3390/brainsci11030306] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 02/22/2021] [Accepted: 02/25/2021] [Indexed: 11/17/2022] Open
Abstract
Transcranial direct current stimulation (tDCS) may enhance speech and language treatment (SLT) for stroke survivors with aphasia; however, to date, there is no standard protocol for the application of tDCS in post-stroke aphasia. We explored the safety and efficacy of fMRI-guided tDCS on functional language and cortical activity when delivered to the lesioned left hemisphere concurrently with SLT across an extended, six-week treatment period. Twelve persons with chronic, nonfluent aphasia following a single left-hemisphere stroke participated in the three-arm (anodal vs. cathodal vs. sham) single-blind, parallel, pilot trial. No serious adverse events occurred during 30 treatment sessions or in the following six weeks. All groups demonstrated functional language gains following intensive treatment; however, active tDCS resulted in greater gains in standardized, probe, and caregiver-reported measures of functional language than sham. Evidence declaring one polarity as superior for inducing language recovery was mixed. However, cathodal stimulation to the lesioned left hemisphere, expected to have a down-regulating effect, resulted in increased areas of cortical activation across both hemispheres, and specifically perilesionally. Generalization of these preliminary findings is limited; however, results are nevertheless compelling that tDCS combined with SLT can be safely applied across extended durations, with the potential to enhance functional language and cortical activation for persons with aphasia.

Abstract
Introduction: Aphasia is a debilitating language disorder and even mild forms of aphasia can negatively affect functional outcomes, mood, quality of life, social participation, and the ability to return to work. Language deficits after post-stroke aphasia are heterogeneous. Areas covered: The first part of this manuscript reviews the traditional syndrome-based classification approach as well as recent advances in aphasia classification that incorporate automatic speech recognition for aphasia classification. The second part of this manuscript reviews the behavioral approaches to aphasia treatment and recent advances such as noninvasive brain stimulation techniques and pharmacotherapy options to augment the effectiveness of behavioral therapy. Expert opinion: Aphasia diagnosis has largely evolved beyond the traditional approach of classifying patients into specific syndromes and instead focuses on individualized patient profiles. In the future, there is a great need for more large scale randomized, double-blind, placebo-controlled clinical trials of behavioral treatments, noninvasive brain stimulation, and medications to boost aphasia recovery.

Abstract
BACKGROUND AND PURPOSE Although many functional magnetic resonance imaging (fMRI) studies have investigated the language architecture and neurobiological mechanism underlying poststroke aphasia (PSA), the pathophysiological mechanisms of PSA still remain poorly understood. In addition to a limited number of subjects (<20) tested with different methodologies and stimuli, inconsistent reports of the brain regions involved have been a major factor. Thus, we conducted a meta-analysis of 12 peer-reviewed studies of abnormal brain activation regions in PSA patients at rest using activation likelihood estimation (ALE). RESULTS A meta-analysis was performed based on 24 experiments with 497 total participants in 12 studies to establish the ALE of regional activation in PSA. Through experiments with PSA patients and healthy controls, we found that hypoactivation in PSA converged on the left superior frontal gyrus and the left parietal postcentral gyrus, whereas there was hyperactivation in the right cerebellar anterior lobe, left fusiform gyrus, left superior parietal lobule, and right subgyral hippocampus. CONCLUSION Our study verified that dominant and nondominant language networks play roles in the recovery of language function.

Follow-Up in Aphasia Caused by Acute Stroke in a Prospective, Randomized, Clinical, and Experimental Controlled Noninvasive Study With an iPad-Based App (Neolexon®): Study Protocol of the Lexi Study. Front Neurol 2020; 11:294. [PMID: 32425873 PMCID: PMC7212356 DOI: 10.3389/fneur.2020.00294] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2020] [Accepted: 03/27/2020] [Indexed: 11/13/2022] Open
Abstract
Rationale: Treatment of aphasia is still challenging for clinicians and patients. So far, there is proven evidence for "face-to-face" speech therapy. However, the digital age potentially offers new and complementary strategies that may add to treatment outcome in a cost-effective way. Neolexon® is a commercial tablet-based software for treatment of aphasia, which can be applied with the help of a therapist or as self-training by the patient. Aims and hypothesis: In the Lexi study, we aim to determine whether treatment with Neolexon® is superior to standard therapy in acute post-stroke aphasia. Sample size estimates: A sample size of 180 patients, 90 for each group, will be included with an assumed dropout rate of ~20%. Methods and design: Prospective, randomized, parallel group, open-label, blinded-endpoint clinical, and experimental controlled non-invasive trial (PROBE). Adult German native speakers with acute aphasia after stroke are included. Computer-generated, blocked, and stratified randomization by aphasia severity will assign patients to one of two groups: 4 weeks of either standard logopedic speech therapy or logopedic speech therapy with the app version of Neolexon®. Both groups will be instructed in self-training: the frequency and duration of self-training will be documented. Screening for aphasia will be performed using the Language Screening Test (LAST). The severity of aphasia in general and in subitems will be assessed using the Bielefelder Aphasie Screening (BIAS) and the Aphasia Check List (ACL). Follow-up will be assessed after 3 months. Study outcomes: Based on the consensus in our study team, we considered a 10% mean difference in the change of percentile rank (PR) of BIAS to be a minimal and clinically important difference. The primary endpoint is defined as a significant difference in BIAS comparing the two groups. Differences in quality of life, Beck Depression Inventory (BDI), and modified Ranking Scale (mRS) will be evaluated as secondary outcome parameters. Discussion: This trial will determine whether speech therapy with the use of Neolexon® is superior to standard logopedic therapy. Subgroups with the greatest response to Neolexon® will be described. The trial was prospectively registered on the "EU Clinical Trials Register" (NCT04080817).
