Binary reversals: a diagnostic sign in primary progressive aphasia. J Neurol Neurosurg Psychiatry 2024; 95:477-480. [PMID: 38071563 DOI: 10.1136/jnnp-2023-331662] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 10/08/2023] [Indexed: 02/22/2024]
Abstract
BACKGROUND Binary reversals (exemplified by 'yes'/'no' confusions) have been described in patients with primary progressive aphasia (PPA) but their diagnostic value and phenotypic correlates have not been defined. METHODS We conducted a retrospective cohort study analysing demographic, clinical, neuropsychological, linguistic and behavioural data from patients representing all major PPA syndromes (non-fluent/agrammatic variant, nfvPPA; logopenic variant, lvPPA; semantic variant, svPPA) and behavioural variant frontotemporal dementia (bvFTD). The prevalence of binary reversals and behavioural abnormalities, illness duration, parkinsonian features and neuropsychological test scores were compared between neurodegenerative syndromes, and the diagnostic predictive value of binary reversals was assessed using logistic regression. RESULTS Data were obtained for 83 patients (21 nfvPPA, 13 lvPPA, 22 svPPA, 27 bvFTD). Binary reversals occurred in all patients with nfvPPA, but significantly less frequently and later in lvPPA (54%), svPPA (9%) and bvFTD (44%). Patients with bvFTD with binary reversals had significantly more severe language (but not general executive or behavioural) deficits than those without reversals. Controlling for potentially confounding variables, binary reversals strongly predicted a diagnosis of nfvPPA over other syndromes. CONCLUSIONS Binary reversals are a sensitive (though not specific) neurolinguistic feature of nfvPPA, and should suggest this diagnosis if present as a prominent early symptom.

[PMID: 35972860 DOI: 10.1080/17483107.2022.2109072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 07/26/2022] [Accepted: 07/29/2022] [Indexed: 10/15/2022]
Abstract
PURPOSE This survey was conducted to investigate American and Indian clinician's preference and usage of high-tech communication supports (HTCS) for aphasia rehabilitation to identify factors in each country that support the use of HTCS for improving post-aphasia communicative outcomes. In this study, HTCS include speech-generating augmentative and alternative communication (AAC) devices with varying methods of access. METHOD The survey exploring clinically practicing speech-language pathologists' (SLPs) training, assessment and aphasia rehabilitation practices using HTCS, was electronically distributed in both countries. The raw responses from the US SLPs (n = 56) and Indian SLPs (n = 43) were collected, segregated and then converted into percentages for all 41 survey questions. RESULTS The responses from SLPs indicated higher (70%) and lower use (58%) of HTCS for aphasia in a developed country (USA) and developing country (India), respectively. In the US, identifiable factors for successful use of HTCS for aphasia rehabilitation were familiarity in procuring and programming the device, caregiver training and effectiveness in reducing the time of communicating through the device. In India, factors leading to successful inclusion of HTCS were AAC coursework and clinical training for clinicians and availability of HTCS at affordable prices for clients. CONCLUSION There is a considerable difference in the educational and clinical practice of AAC as SLPs in the US tend to have more clinical AAC experience with a stronger network for device dissemination in comparison to SLPs in India leading to higher usage of high-tech AAC for aphasia rehabilitation in a developed country.Implications for RehabilitationFor the SLPs,Improve exposure to programming AAC devices in developed countries and increase coursework, clinical training and exposure to programming AAC devices in developing countries.Enhance awareness about integrating high-tech AAC devices in intervention programs.Improve efficiency by minimizing the time in message creation on high-tech AAC device in developed countries. For the bioengineers,Develop AAC application interfaces in regional languages for easier usage in developing countries.

Abstract
Speech disorders are associated with different degrees of functional and structural abnormalities. However, the abnormalities associated with specific disorders, and the common abnormalities shown by all disorders, remain unclear. Herein, a meta-analysis was conducted to integrate the results of 70 studies that compared 1843 speech disorder patients (dysarthria, dysphonia, stuttering, and aphasia) to 1950 healthy controls in terms of brain activity, functional connectivity, gray matter, and white matter fractional anisotropy. The analysis revealed that compared to controls, the dysarthria group showed higher activity in the left superior temporal gyrus and lower activity in the left postcentral gyrus. The dysphonia group had higher activity in the right precentral and postcentral gyrus. The stuttering group had higher activity in the right inferior frontal gyrus and lower activity in the left inferior frontal gyrus. The aphasia group showed lower activity in the bilateral anterior cingulate gyrus and left superior frontal gyrus. Across the four disorders, there were concurrent lower activity, gray matter, and fractional anisotropy in motor and auditory cortices, and stronger connectivity between the default mode network and frontoparietal network. These findings enhance our understanding of the neural basis of speech disorders, potentially aiding clinical diagnosis and intervention.

Abstract
BACKGROUND We aimed to validate the Clinical Dementia Rating (CDR®) dementia staging instrument plus the National Alzheimer's Coordinating Centre Behaviour and Language Domains (CDR® plus NACC FTLD) for use in clinical settings in Japan and in the Japanese language. METHODS This prospective observational study enrolled 29 patients with frontotemporal dementia (FTD) and 21 patients with Alzheimer's disease (AD) dementia from the Departments of Psychiatry at Osaka University Hospital and Asakayama General Hospital and the Brain Function Centre at Nippon Life Hospital. CDR® plus NACC FTLD, CDR®, Mini-Mental State Examination (MMSE), Western Aphasia Battery (WAB), Neuropsychiatric Inventory-plus (NPI-plus), Stereotypy Rating Inventory (SRI), and frontal behavioural symptom scores obtained from items of NPI-plus and SRI, were conducted to assess inter- and intra-rater reliability, validity, and responsiveness. We performed receiver operating characteristic (ROC) curve analysis to evaluate the discriminating power of the Behaviour/Comportment/Personality (BEHAV) and Language (LANG) domains of the CDR® plus NACC FTLD and the MEMORY domain of the CDR® in patients AD dementia and FTD. RESULTS The CDR® plus NACC FTLD showed good inter- and intra-rater reliabilities. In patients with FTD, the BEHAV domain of the CDR® plus NACC FTLD was significantly correlated with all clinical measures except for the SRI total score, while the LANG domain of the CDR® plus NACC FTLD was significantly correlated with the MMSE and the WAB-Aphasia quotient. In addition, the CDR® plus NACC FTLD sum of boxes significantly changed after 6 months and after 1 year. ROC curve analysis showed that the BEHAV and LANG domains of the CDR® plus NACC FTLD distinguished between patients with AD dementia and FTD better than the MEMORY domain of the CDR®. CONCLUSIONS This study validated the Japanese version of the CDR® plus NACC FTLD with good reliability, validity, and responsiveness.

Abstract
BACKGROUND The classical Wada test (cWada), performed by injecting a short-acting anesthetic through the intracarotid route, helps determine language dominance. In the cWada, adverse effects are observed in 10-30% of trials, hindering accurate assessments. In this study, we assessed the effectiveness of the super-selective Wada test (ssWada), a more selective approach for anesthetic infusion into the middle cerebral artery (MCA). METHODS We retrospectively examined the data of 17 patients with epilepsy who underwent ssWada via anesthetic injection into one M1 segment of the MCA and at least one contralateral trial. RESULTS The ssWada identified 12 patients with left language dominance, 3 with right language dominance, and 2 with bilateral language distribution. Nine trials on the language dominant side resulted in global aphasia for patients with left- or right language dominance. Of the 13 trials conducted on the non-dominant language side, 12 revealed intact language function and one resulted in confusion. Among these, the outcomes of global aphasia or no language impairment were confirmed in the contralateral trials. Among the 22 trials of unilateral M1 injections in patients with unilateral language dominance, 21 (95.5%) showed either global aphasia or no language impairment, indicating language dominance. CONCLUSIONS The ssWada yields clear results, with a high rate of over 90% in determining the language dominant hemisphere with few side effects.

Abstract
PURPOSE Many people with aphasia have inadequate language skills for functional communication thereby necessitating well-designed augmentative and alternative communication (AAC) interfaces. Using both a grid and a VSD interface with single word hotspots by neurologically healthy adults, across ages and with different technology experiences, this study examines the utility of these interfaces prior to investigating their use with people with aphasia in future studies. METHOD Participants include 18 young adults, 24 older adults with technology experience, and 20 older adults with limited technology experience. The older adult groups were matched for mean age and for sex. Participants described pictures with each interface, and performance was measured based on four dependent variables: (a) the total number of correct information units (CIUs), (b) the percentage of CIUs, (c) CIUs per minute, and (d) preferred interface. RESULTS There was a significant difference between older adults and the young adult group for the total number of CIUs (p < 0.001) and CIUs per minute (p < 0.001). Despite the changes in technology experience between the two older groups, there was no significant difference in performance. Additionally, there was no significant difference in performance across the two interfaces in any of the groups. CONCLUSION Findings suggest age does impact performance on AAC. However, the difference in technology experience in older adult groups did not affect performance. Furthermore, both interfaces used in the current study were equally beneficial when describing pictures by healthy adults. Implications for RehabilitationAugmentative and alternative communication (AAC) systems involve various interface designs. Consequently, the comparative utility of these interfaces must be examined across populations and communicative functions.Advancement in technology has given rise to numerous high-tech AAC interface designs. However, older adults with acquired language difficulties whose technology experience is limited may become reluctant to use high-tech AAC. Hence, the influence of technology experience on high-tech AAC performance should be investigated.Prior to examining interfaces with individuals with acquired language difficulties, the current study examined the use of a) grid display and b) visual scene display (VSD) with single word hotspots, by healthy adults of different ages and technology experiences.The study revealed that older adults with limited technology experience were equally competent in using high-tech AAC interfaces, as those with technology experience. Hence, an individual's technology experience should not be considered a deterrent to using high-tech AAC interfaces.Additionally, the study found no differences in performance between the two interfaces, making it essential to consider user's personal preference when adopting AAC interface designs.

Abstract
Nowadays, Henry Head is best known for his Head zones. The concept was understood very differently by Head in comparison to what current medical books falsely describe them to be. In reality, there is no direct relationship between one particular skin zone and one single organ. It is certain that the drawings considered depictions of the Head zones in today's medical textbooks were actually not created by Head. From a neurological point of view, Head is important for two reasons: his self-experiment in 1909 to damage one of his own peripheral nerves followed by regeneration was heroic. It has helped generations of neurologists to have a better understanding of the pathophysiology of peripheral nerve damage and thus make a better assessment of the prognosis of such injuries. Head's second contribution pertains to the radicular organization at the level of the spinal cord. The pathophysiology of herpes zoster radiculitis enabled him to develop the concept of the dermatomes on the basis of preliminary work around 1900. Henry Head's contribution was the systematic compilation of the existing publications of the time and amendment of his own cases. As he was the most important neurologist at that time, at least in the English speaking world, and was well connected with people in the German neurology community, it was probably easy for him to make his dermatome maps well known. In retrospect, Head was less successful in neuropsychology with holistic concepts for higher cognitive functions which were in vogue during his lifetime. His late work on aphasia is now considered refuted. Head's criticism of the strict localization was well in syncronization with the zeitgeist of the early twentieth century. Establishing the fact that Broca's aphasia and Wernicke's aphasia are not easily diagnostically distinguishable from each other was more an achievement of subsequent generations of neurologists and neuropsychologists as well as technical advances.

Abstract
Studies on the neural bases of sentence production have yielded mixed results, partly due to differences in tasks and participant types. In this study, 101 individuals with primary progressive aphasia (PPA) were evaluated using a test that required spoken production following an auditory prime (Northwestern Assessment of Verbs and Sentences-Sentence Production Priming Test, NAVS-SPPT), and one that required building a sentence by ordering word cards (Northwestern Anagram Test, NAT). Voxel-Based Morphometry revealed that gray matter (GM) volume in left inferior/middle frontal gyri (L IFG/MFG) was associated with sentence production accuracy on both tasks, more so for complex sentences, whereas, GM volume in left posterior temporal regions was exclusively associated with NAVS-SPPT performance and predicted by performance on a Digit Span Forward (DSF) task. Verb retrieval deficits partly mediated the relationship between L IFG/MFG and performance on the NAVS-SPPT. These findings underscore the importance of L IFG/MFG for sentence production and suggest that this relationship is partly accounted for by verb retrieval deficits, but not phonological loop integrity. In contrast, it is possible that the posterior temporal cortex is associated with auditory short-term memory ability, to the extent that DSF performance is a valid measure of this in aphasia.

Abstract
PURPOSE Prior studies have shown that people with aphasia (PWA) have demonstrated superior language performance for emotional compared to nonemotional stimuli on a range of tasks, including auditory comprehension, verbal pragmatics, repetition, reading, and writing. However, studies on word retrieval, specifically, have suggested a possible interference effect of emotion on naming. The purpose of this study was to examine the effect of the emotional valence of stimuli on word retrieval in a series of naming tasks in PWA. METHOD Thirteen PWA and 13 neurotypical controls participated in four single-word naming tasks, including 1) object picture naming, 2) action picture naming, 3) category-member generation, and 4) verb generation. Each task included three valence sets of positively-, negatively-, and neutrally-rated pictures or words, which were obtained from the standardized International Affective Picture System (Lang et al., 2008) and the Affective Norms for Emotional Words (Bradley and Lang, 1999) databases. Accuracy and reaction time (RT) were measured and compared across groups, tasks, and valence sets. RESULTS Emotional stimuli, especially negative stimuli, resulted in worse naming performance, as measured by accuracy and RT, compared to nonemotional stimuli in PWA and neurotypical controls. This effect was relatively robust across the four naming tasks. In most cases, negative stimuli resulted in lower accuracy and slower RT than positive stimuli. CONCLUSIONS These findings suggest that stimulus valence may interfere with word retrieval for PWA and neurotypical adults and that this effect is robust across different types of naming tasks that vary by word class (nouns versus verbs) and stimulus type (pictures versus words). Negative stimuli resulted in worse naming performance than positive stimuli. These results suggest that emotionality of stimuli is an important variable to consider in word retrieval research.

Abstract
The fusion of electroencephalography (EEG) with machine learning is transforming rehabilitation. Our study introduces a neural network model proficient in distinguishing pre- and post-rehabilitation states in patients with Broca's aphasia, based on brain connectivity metrics derived from EEG recordings during verbal and spatial working memory tasks. The Granger causality (GC), phase-locking value (PLV), weighted phase-lag index (wPLI), mutual information (MI), and complex Pearson correlation coefficient (CPCC) across the delta, theta, and low- and high-gamma bands were used (excluding GC, which spanned the entire frequency spectrum). Across eight participants, employing leave-one-out validation for each, we evaluated the intersubject prediction accuracy across all connectivity methods and frequency bands. GC, MI theta, and PLV low-gamma emerged as the top performers, achieving 89.4%, 85.8%, and 82.7% accuracy in classifying verbal working memory task data. Intriguingly, measures designed to eliminate volume conduction exhibited the poorest performance in predicting rehabilitation-induced brain changes. This observation, coupled with variations in model performance across frequency bands, implies that different connectivity measures capture distinct brain processes involved in rehabilitation. The results of this paper contribute to current knowledge by presenting a clear strategy of utilizing limited data to achieve valid and meaningful results of machine learning on post-stroke rehabilitation EEG data, and they show that the differences in classification accuracy likely reflect distinct brain processes underlying rehabilitation after stroke.

Abstract
BACKGROUND People with aphasia are vulnerable recipients of healthcare. The nature of the communicative environment and the communication disability can adversely impact access to timely and quality healthcare. Student healthcare professionals are often underprepared to interact successfully with people with aphasia and may benefit from communication partner training (CPT). AIMS To investigate the potential effectiveness and acceptability of a brief, two-part introductory Supported Conversation for Adults with Aphasia (SCA™)-based CPT package, delivered to a sample of students across a diverse range of healthcare disciplines. METHODS & PROCEDURES A pre-post-within group experimental design was used to investigate the potential effectiveness and acceptability of an online CPT package (50 minute module + 1 hour workshop) for healthcare students. The Aphasia Attitudes, Strategies and Knowledge (AASK) survey measured participants' knowledge of aphasia, facilitative communication strategies and attitudes towards people with aphasia. Data were collected pre-training, following the training module and following the workshop, and 6 weeks post-training. Statistical analysis was conducted on the AASK data. In addition, participant feedback (ratings and open text responses) was collected after the workshop. Ratings were analysed descriptively, and thematic content analysis was used for open text responses. OUTCOMES & RESULTS 236 participants completed the pre-training AASK and 106 completed the AASK at subsequent time points. Statistically significant gains were demonstrated from pre- to post-module completion. Between the end of the module and the end of the workshop, some gains were maintained and others showed further statistically significantly improvements. While all gains were not maintained at the 6-week follow-up, statistically significantly improvements from pre-training scores remained evident. Student feedback was predominantly positive, with suggested improvements for training content and length. CONCLUSIONS & IMPLICATIONS The results provide preliminary evidence that a brief, online CPT package can support student healthcare professionals' knowledge and attitudes towards aphasia and communicating with people with aphasia. Online training was acceptable to students and feasible as an embedded or optional component of curriculum. Ongoing training (e.g., in the form of refresher sessions) and inclusion of a skills-based component are recommended to maximize communication skill development. WHAT THIS PAPER ADDS What is already known on the subject Student healthcare professionals recognize the need to develop knowledge and skills to successfully support people with communication disability, such as aphasia, to participate effectively in their healthcare. Evidence in favour of online communication partner training for student healthcare professionals is currently limited. What this study adds to the existing knowledge This study demonstrates that a brief introductory online communication partner training program can be efficacious for improving knowledge and attitudes regarding communicating with people who have aphasia. What are the potential or actual clinical implications of this work? Students will likely need further ongoing refresher training with inclusion of practical components to develop and maintain the knowledge and skills required to be proficient communication partners with people with aphasia.

Abstract
BACKGROUND Posterior cortical atrophy (PCA) and logopenic progressive aphasia (LPA) are two common atypical Alzheimer's disease (AD) variants. Little is known about behavioral and neuropsychiatric symptoms or activities of daily living (ADLs) in PCA and LPA, and whether they differ across syndromes. OBJECTIVE To characterize the behavioral and neuropsychiatric profiles and ADLs of PCA and LPA and compare presence/absence and severity of symptoms between syndromes. METHODS Seventy-eight atypical AD patients, 46 with PCA and 32 with LPA, completed the Neuropsychiatric Inventory Questionnaire (NPI-Q) and Cambridge Behavioral Inventory-Revised (CBI-R) at baseline and longitudinally over-time. Mann-Whitney U and Fisher's Exact Tests assessed for differences in symptoms between the two syndromes with significance set at p≤0.01. To eliminate demographic differences as confounders the groups were matched, and differences reanalyzed. RESULTS PCA were younger at onset (p = 0.006), at time of baseline assessment (p = 0.02) and had longer disease duration (p = 0.01). Neuropsychiatric symptoms were common in PCA and LPA, although more common and severe in PCA. At baseline, PCA had a higher NPI-Q total score (p = 0.01) and depression subscore (p = 0.01) than LPA. Baseline total CBI-R scores were also higher in PCA than LPA (p = 0.001) with PCA having worse scores in all 10 CBI-R categories. Longitudinally, there was no difference between groups on the NPI-Q. However, on the CBI-R, PCA had faster rates of worsening on self-grooming (p = 0.01) and self-dressing (p = 0.01) compared to LPA. CONCLUSIONS Behavioral and neuropsychiatric symptoms are common in PCA and LPA although these symptoms are more common and severe in PCA.

Abstract
Negative symptoms of schizophrenia remain clinically and theoretically understudied and represent an unmet psychiatric need. Negative symptoms are assumed to be related to other psychiatric disorders, but their association with dissociative symptoms is yet to be explored, particularly in light of depression and anxiety symptoms. We examined the five domains of negative symptoms (anhedonia, asociality, avolition, blunted affect and alogia) in an Israeli national sample of 1930 participants of whom 645 (33.4%) were with increased risk for dissociative disorder. The results show that anhedonia, blunted affect and alogia significantly associated with risk for dissociative disorder, above and beyond depression and anxiety. When assessing for negative symptoms it may be worth screening for dissociation and vice versa and thus make a more accurate clinical picture of the interplay between them.

Abstract
Background The mechanism(s) of cognitive impairment remains complex, making it difficult to confirm the factors influencing poststroke cognitive impairment (PSCI). Objective This study quantitatively investigated the degree of influence and interactions of clinical indicators of PSCI. Methods Information from 270 patients with PSCI and their Wechsler Adult Intelligence Scale (WAIS-RC) scores, totaling 18 indicators, were retrospectively collected. Correlations between the indicators and WAIS scores were calculated. Multiple linear regression model(MLR), genetic algorithm modified Back-Propagation neural network(GA-BP), logistic regression model (LR), XGBoost model (XGB), and structural equation model were used to analyze the degree of influence of factors on the WAIS and their mediating effects. Results Seven indicators were significantly correlated with the WAIS scores: education, lesion side, aphasia, frontal lobe, temporal lobe, diffuse lesions, and disease course. The MLR showed significant effect of education, lesion side, aphasia, diffuse lesions, and frontal lobe on the WAIS. The GA-BP included five factors: education, aphasia, frontal lobe, temporal lobe, and diffuse lesions. LR predicted that the lesion side contributed more to mild cognitive impairment, while education, lesion side, aphasia, and course of the disease contributed more to severe cognitive impairment. XGB showed that education, side of the lesion, aphasia, and diffuse lesions contributed the most to PSCI. Aphasia plays a significant mediating role in patients with severe PSCI. Conclusions Education, lesion side, aphasia, frontal lobe, and diffuse lesions significantly affected PSCI. Aphasia is a mediating variable between clinical information and the WAIS in patients with severe PSCI.

Abstract
OBJECTIVE The paper deals with the possibilities of the development and the support of individuals with developmental dysphasia with regard to the legislative framework of the Czech Republic in the field of education and presents the results of a systematic case study of a child patient diagnosed with developmental dysphasia (according to ICD-10; F80.1 and F80.2). CASE REPORT The study aimed to determine the effect of combined therapy using long-term special educational, rehabilitation and psychological intervention, speech therapy and music therapy on the development of the patient's communication skills. The proband was selected by random, stratified sampling based on pre-determined relevant characteristics (age 6 years i.e., before entering primary school, diagnosed with developmental dysphasia). A 6-year-old child patient participated in the research with the consent of the legal representative. The therapy was focused on special educational care, speech therapy, music therapy and psychological intervention (including psychotherapy). During the hospitalization and post-hospitalization care, there was also the presence of a physiotherapist and an occupational therapist. CONCLUSION The results of the research point out the need for regular and close multidisciplinary cooperation of an occupational therapist, a physiotherapist, a special educator, a speech therapist, a music therapist and a psychologist when working with patients diagnosed with developmental dysphasia. These professions focus specifically on specific areas of support with a focus on cognitive, phatic and motor functions with the support of social adaptability.

Baker C, Love T. Modulating Complex Sentence Processing in Aphasia Through Attention and Semantic Networks. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2023; 66:5011-5035. [PMID: 37934886 PMCID: PMC11001378 DOI: 10.1044/2023_jslhr-23-00298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 08/05/2023] [Accepted: 09/07/2023] [Indexed: 11/09/2023]
Abstract
PURPOSE Lexical processing impairments such as delayed and reduced activation of lexical-semantic information have been linked to syntactic processing disruptions and sentence comprehension deficits in individuals with aphasia (IWAs). Lexical-level deficits can also preclude successful lexical encoding during sentence processing and amplify the processing costs of similarity-based interference during syntactic retrieval. We investigate whether two manipulations to engage attention and pre-activate semantic features of a target (to-be-retrieved) noun will (a) boost lexical activation during initial lexical encoding and (b) facilitate syntactic dependency linking through improved resolution of interference in IWAs and neurologically unimpaired age-matched controls (AMCs). METHOD Eye-tracking-while-listening with a visual world paradigm was used to investigate whether semantic and attentional manipulations modulated initial lexical processing and downstream syntactic retrieval of the direct-object noun in object-relative sentences. RESULTS In the attention and semantic manipulations, the AMC group showed no changes in initial lexical access levels; however, gaze patterns revealed clear facilitations in dependency linking and interference resolution. In the IWA group, the attentional cue increased and maintained activation of N1 with modest facilitations in dependency linking. In the semantic condition, IWA results showed a greater degree of facilitation during dependency linking. CONCLUSIONS The results suggest that attention and semantic activation are parameters that may be manipulated to strengthen encoding of lexical representations to facilitate retrieval (i.e., dependency linking) and mitigate similarity-based interference. In IWAs, these manipulations may help to reduce lexical processing deficits that can preclude successful encoding.

Abstract
Introduction: Damage to white matter tracts can cause severe neurological deficits, which are often hardly predictable before brain tumor surgery. To explore the possibility of assessing white matter integrity and its preservation, we chose the frontal aslant tract (FAT) due to its involvement in multiple neurological functions such as speech and movement initiation. Methods: Right-handed patients with left hemispheric intracerebral tumors underwent FAT tractography within 7 days before and 3 days after surgery. Neurological performance score and aphasia score were assessed within 7 days before and after surgery, as well as at follow-up 3 months postoperatively. Results: Fifteen patients were prospectively analyzed. After multivariate analysis and receiver operating characteristic analysis, we found that preoperative fractional anisotropy (FA) of the left FAT indicated the preoperative aphasia score (cutoff 0.40, p = 0.015). Aphasia scores 3 months postoperatively were predicted by both postoperative FA of the left FAT (cutoff 0.35, p = 0.005) and postoperatively preserved FA of the left FAT (cutoff 95.8%, p = 0.017). Postoperatively preserved right FAT FA inversely predicted postoperative aphasia score (cutoff 95.1%, p = 0.016). Discussion: Assessment of white matter integrity preservation is possible and correlates with outcome after brain tumor surgery. It may be useful for patient counseling and assessment of rehabilitation potential, as well as to investigate relevant brain networks in the future. Clinical Trial Registration: The trial was prospectively registered at ClinicalTrials.gov (NCT04302857).

Abstract
PURPOSE Self-Reporting using traditional text-based Quality-of-Life (QoL) instruments can be difficult for people living with sensory impairments, communication challenges or changes to their cognitive capacity. Adapted communication techniques, such as Easy-Read techniques, or use of pictures could remove barriers to participation for a wide range of people. This review aimed to identify published studies reporting adapted communication approaches for measuring QoL, the methodology used in their development and validation among adult populations. METHODS A scoping review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews checklist was undertaken. RESULTS The initial search strategy identified 13,275 articles for screening, with 264 articles identified for full text review. Of these 243 articles were excluded resulting in 21 studies for inclusion. The majority focused on the development of an instrument (12 studies) or a combination of development with some aspect of validation or psychometric testing (7 studies). Nineteen different instruments were identified by the review, thirteen were developed from previously developed generic or condition-specific quality of life instruments, predominantly aphasia (7 studies) and disability (4 studies). Most modified instruments included adaptations to both the original questions, as well as the response categories. CONCLUSIONS Studies identified in this scoping review demonstrate that several methods have been successfully applied e.g. with people living with aphasia post-stroke and people living with a disability, which potentially could be adapted for application with more diverse populations. A cohesive and interdisciplinary approach to the development and validation of communication accessible versions of QOL instruments, is needed to support widespread application, thereby reducing reliance on proxy assessors and promoting self-assessment of QOL across multiple consumer groups and sectors.

Abstract
In the field of neurodegeneration, speech and language assessments are useful for diagnosing aphasic syndromes and for characterizing other disorders. As a complement to classic tests, scalable and low-cost digital tools can capture relevant anomalies automatically, potentially supporting the quest for globally equitable markers of brain health. However, this promise remains unfulfilled due to limited linguistic diversity in scientific works and clinical instruments. Here we argue for cross-linguistic research as a core strategy to counter this problem. First, we survey the contributions of linguistic assessments in the study of primary progressive aphasia and the three most prevalent neurodegenerative disorders worldwide-Alzheimer's disease, Parkinson's disease, and behavioural variant frontotemporal dementia. Second, we address two forms of linguistic unfairness in the literature: the neglect of most of the world's 7000 languages and the preponderance of English-speaking cohorts. Third, we review studies showing that linguistic dysfunctions in a given disorder may vary depending on the patient's language and that English speakers offer a suboptimal benchmark for other language groups. Finally, we highlight different approaches, tools and initiatives for cross-linguistic research, identifying core challenges for their deployment. Overall, we seek to inspire timely actions to counter a looming source of inequity in behavioural neurology.

Abstract
PURPOSE Moyamoya disease (MMD) is an uncommon chronic and occlusive cerebrovascular disorder involving the development of abnormal collateral vessels. This report aimed to describe a Chinese familial case with a rare variant in the RNF213 gene. METHODS The present report presents a rare familial case of MMD involving a heterozygous c.14429G>A variant in RNF213 and exhibiting different phenotypes. RESULTS A 3-year-old Chinese boy and his 10-year-old sister diagnosed severe bilateral MMD, while their mother was diagnosed asymptomatic bilateral MMD, based on the imaging results of magnetic resonance angiography (MRA). The boy mainly showed numbness at left hand accompanied by dysphasia and dyskinesia, while his sister had complex symptoms including dysphasia, dyskinesia at both hands and fatigue of limbs. Muscle force was ranked as left (upper limb/lower limb: 4/3) and right (upper limb/lower limb: 3/4). Genetic testing indicated a heterozygous c.14429G>A variant in RNF213 in 3 patients. The 3 patients shared the same amino acid substitution of p.Arg4810Lys caused by c.14429G>A. The father of two children also underwent genetic testing for RNF213 and MRI examination but found normal in all indices. CONCLUSIONS Genetic testing for RNF213 is suggested for MMD screening towards family members, and c.14576G>A variant is identified as an important pathogenic mutation with family heritability.

A content thematic analysis of medical records and incident reports on the falls of hospital patients with communication disability following stroke. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2023; 58:2033-2048.

Abstract
BACKGROUND People with communication disability following stroke are at risk of falls during inpatient rehabilitation. However, they are often excluded from hospital falls research, and little is known about the circumstances or outcomes of their falls to inform risk management strategies. AIMS To examine hospital medical records and incident reports relating to falls of patients with communication disability following stroke for content codes, categories and themes relating to communication. METHODS & PROCEDURES This medical record chart review examined data on 72 patients and 265 falls. A content thematic analysis was used to identify how patient communication is characterized in relation to falls, and their prevention and management strategies. OUTCOMES & RESULTS The data reflected that staff viewed patients having difficulty following simple instructions as contributing to falls. Gaining the attention of staff and communicating basic needs were also considered to be contributing factors for falls. Patients were often described as experiencing a fall when taking a risk or attempting to address an unmet basic need. Furthermore, written notes for patients with more severe communication disability reflected that the patient's communication impairments prevented staff from establishing the circumstances of some falls and complicated the assessment for injury following a fall. CONCLUSIONS & IMPLICATIONS The medical records and incident reports of patients with communication disability following stroke reveal that hospital staff recognize the impact of communication disability as potential risk factors for falls for this group. It was difficult for staff to report the circumstances of the fall for patients with severe communication disability. Despite the recognition of communication as a potential contributing factor, few medical record entries documented strategies related to communication interventions to improve patients' ability to understand instructions, gain attention or communicate basic needs. WHAT THIS PAPER ADDS What is already known on the subject People with stroke are at a high risk of falls during their hospital admission. However, little is known about the circumstances of their falls and the influence of communication disability on these falls. What this paper adds to existing knowledge Patients with communication disability have unique factors that contribute to their falls in the hospital. Patients were described as experiencing a fall when taking a risk or attempting to address an unmet need, and these falls were often related to a patient's difficulties communicating their basic needs, gaining attention from staff, and following simple instructions. What are the potential or actual clinical implications of this work? Communication disability as a risk factor for a fall, and fall prevention strategies tailored to the communication disability, were typically identified and documented by physiotherapists, occupational therapists and nursing staff. The inclusion of speech pathologists in fall risk assessment, management, and prevention strategies may provide crucial information regarding the patient's communication disability that may enhance their fall prevention plan.

Abstract
The aim of the present article is to preserve, in English translation, two historical communications on aphasia and the pathophysiology of language by the neurobiologist Christfried Jakob (1866-1956) of Buenos Aires, and to place them in a modern perspective. The morphofunctional basis of human language and its pathology occupied Jakob's mind over three decades. His synthetic conclusions were based on the neuropathological examination of dozens of aphasic cases from the Hospital de Las Mercedes and the National Women's Psychiatric Hospital between 1906 and 1936. Special mention is made of the role of the cerebellum, the thalamus, and their connections with the cerebral cortex, and the language network. Current research and imaging studies support and elaborate that which Jacob presented so many years ago; many of his analyses and ideas are informative and remain relevant today.
