Impairments in knowledge of social norms in presymptomatic, prodromal, and symptomatic frontotemporal dementia.

INTRODUCTION: We aimed to assess the knowledge of social norms in patients with behavioral variant frontotemporal dementia (bvFTD) with the Dutch version of the Social Norms Questionnaire (SNQ-NL). METHODS: The SNQ-NL was administered in 34 patients with bvFTD, 20 prodromal mutation carriers, 76 presymptomatic mutation carriers, and 56 controls. Group differences and correlations with other neuropsychological tests and gray matter volume were examined. RESULTS: Patients with bvFTD had lower total SNQ-NL scores and more over-adherence errors than presymptomatic mutation carriers and controls (P < 0.001). SNQ-NL performance correlated with tests for executive functioning and social cognition, and with gray matter volume in bilateral frontal and unilateral temporal regions. DISCUSSION: The SNQ-NL can identify impairments in knowledge of social norms in bvFTD, highlighting its significance in clinical diagnosis and upcoming clinical trials. The SNQ-NL currently fails to differentiate presymptomatic mutation carriers from controls; to this end, larger sample sizes from larger cohorts and longitudinal follow-up are warranted. Highlights: The Dutch version of the Social Norms Questionnaire (SNQ-NL) is able to detect impairment in social cognition in symptomatic bvFTD patients.A trend towards a lower performance in prodromal mutation carriers was found.Performance on the SNQ-NL is related to other measures of social cognition, executive functioning, and language.Lower SNQ-NL performance is related to gray matter volume loss in bilateral frontal and temporal regions.The SNQ-NL provides insight into the underlying cause of deficits in social cognition in bvFTD.

Neurodevelopmental profiles of 14 individuals with phosphomannomutase deficiency (PMM2-CDG).

PMM2-CDG (formerly CDG-1a), the most common type of congenital disorders of glycosylation, is inherited in an autosomal recessive pattern. PMM2-CDG frequently presents in infancy with multisystemic clinical involvement, and it has been diagnosed in over 1000 people worldwide. There have been few natural history studies reporting neurodevelopmental characterization of PMM2-CDG. Thus, a prospective study was conducted that included neurodevelopmental assessments as part of deep phenotyping. This study, Clinical and Basic Investigations into Known and Suspected Congenital Disorders of Glycosylation (NCT02089789), included 14 participants (8 males and 6 females ages 2-33 years) with a confirmed molecular diagnosis of PMM2-CDG. Clinical features of PMM2-CDG in this cohort were neurodevelopmental disorders, faltering growth, hypotonia, cerebellar atrophy, peripheral neuropathy, movement disorders, ophthalmological abnormalities, and auditory function differences. All PMM2-CDG participants met criteria for intellectual disability (or global developmental delay if younger than age 5). The majority never attained certain gross motor and language milestones. Only two participants were ambulatory, and almost all were considered minimally verbal. Overall, individuals with PMM2-CDG present with a complex neurodevelopmental profile characterized by intellectual disability and multisystemic presentations. This systematic quantification of the neurodevelopmental profile of PMM2-CDG expands our understanding of the range in impairments associated with PMM2-CDG and will help guide management strategies.

Executive functions and their relationship with age: Insights from a novel neuropsychological Assessment Battery in Children-a pilot study.

Executive functions (EFs) are a set of cognitive processes that enable individuals to manage and coordinate their thoughts and actions toward achieving specific goals. EFs include planning, organizing, initiating, and monitoring actions, and have been found to improve with age due to the maturation of the brain, especially during childhood. Therefore, our correlational study sought to determine the relationship between the performance in executive functions and age in 79 children (36 girls, 45.6%) throughout development, between the ages of 6 and 12 (mean = 9.25; SD = 2.05), using a battery designed in Chile: BEFE (Batería de Evaluación de las Funciones Ejecutivas: Executive Function Assessment Battery) based on traditional neuropsychological tests to evaluate Working Memory, Inhibitory Control, Cognitive Flexibility, and Planning skills. Our results showed various correlations between the variables age and performance in various behavioral parameters, demonstrating an increase in the number of correct responses (positive correlation) and/or a decrease in errors (negative correlation) with age (6-12) in the subtests that correspond to dimensions of Cognitive Flexibility (Semantic and Phonological Fluency, Card Sorting Game, and Tracing Tasks), Inhibitory Control (ENA-F and Sentence Completion), Working Memory (Audio-verbal WM Forward and Ordering, and Visuospatial WM Forward and Backward), and Planning (La Portada de Antofagasta and FISA Maps). These results are consistent with previous empirical evidence and support the notion of a developmental relationship between EF performance and age. Additionally, this study contributes to understanding EF development in culturally specific contexts, highlighting the importance of contextually relevant assessment tools in evaluating cognitive development.

Neuropsychology practice guidance for the neuropsychiatric aspects of Long COVID.

Objective: The coronavirus disease-2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has had a profound global impact on individual health and well-being in adults and children. While most fully recover from COVID-19, a relatively large subgroup continues to experience persistent physical, cognitive, and emotional/behavioral symptoms beyond the initial infection period. The World Health Organization has termed this phenomenon "Post-COVID-19 Condition" (PCC), better known as "Long COVID." Due to the cognitive and psychosocial symptoms, neuropsychologists often assess and recommend treatment for individuals with Long COVID. However, guidance for neuropsychologists' involvement in clinical care, policy-making, and research has not yet been developed. The authors of this manuscript convened to address this critical gap and develop guidance for clinical neuropsychologists working with patients presenting with Long COVID. Method: Authors include pediatric and adult neuropsychologists with expertise in Long COVID and behavioral health. All authors have been engaged in clinical and research efforts examining the impact of COVID-19. Authors summarized the literature-to-date pertinent to the neuropsychiatric sequelae of Long COVID and developed guidance for neuropsychologists working with individuals with Long COVID. Conclusions: Research findings regarding neuropsychiatric symptoms associated with Long COVID are mixed and limited by methodological differences. As they practice and conduct research, neuropsychologists should remain mindful of the evolving and tenuous nature of the literature.

Prevalence of neurocognitive impairment in patients with rheumatoid arthritis - a systematic review and meta-analysis.

ObjectiveThis study aimed to evaluate prevalence rates (PRs) of neurocognitive impairment and its potential moderators among patients with rheumatoid arthritis (RA). MethodA systematic review of the available literature and data extraction was undertaken on 6 August 2021, with the update by 14 September 2023, by two reviewers independently. Literature was screened for reported rates of prevalence of neurocognitive impairment in RA patients. The meta-analysis was performed using RStudio with the "meta" library. ResultsTwenty-two studies that fulfilled all selection criteria were carefully analyzed. The PR of neurocognitive impairment was 0.49 [0.38-0.61] across all studies included in the review; 0.75 [0.54-0.88] for the MoCA; 0.56 [0.40-0.72] for the MMSE; and 0.26 [0.16-0.38] for comprehensive batteries. The meta-regression results indicated that, depending on the measurement method, the percentage of subjects with positive rheumatoid factor, women ratio, mean age of participants, mean duration of RA, and percentage of domains that had to be impaired to diagnose neurocognitive impairment turned out to be statistically significant moderators. ConclusionsNeurocognitive impairment is a clinically relevant condition in many RA patients, and its prevalence is alarming high.

Rheumatoid arthritis (RA) is a chronic systemic disease that has a significant negative impact on functioning. Difficulties experienced by RA patients described in the literature may involve various organs and systems, including the central nervous system. The results obtained in the review indicate that cognitive impairment may affect, depending on the measurement method, up to approximately 75% of the patients. Due to potential limitations related to cognitive dysfunctions, such as reduced compliance or difficulties in everyday functioning, such a high prevalence of neurocognitive dysfunctions is an argument for screening RA patients and developing appropriate support methods.

Immediate post-concussion assessment and cognitive testing Pediatric (ImPACT Pediatric) change scores and factors associated with performance in patients aged 5-9 years following concussion: Preliminary findings.

BACKGROUND: Computerized neurocognitive testing is one component of a multidomain assessment of concussion. However, the use of computerized neurocognitive testing has been limited to patients aged 11 years and up, leaving clinicians with few options to evaluate younger children. PURPOSE: To examine the change in Immediate Post-concussion Assessment and Cognitive Testing Pediatric (ImPACT Pediatric) (ImPACT Applications, 2021) scores and factors associated with performance in children aged 5-9 years following a concussion. METHODS: Participants included 63 children (42% [n = 27] female) aged 5-9 (M = 7.5 ± 1.0) years within 30 (M = 8.5 ± 5.9) days of a concussion. All participants completed the ImPACT Pediatric at their initial visit and at medical clearance for their return to activity (RTA) visit. The ImPACT Pediatric test is a computerized neurocognitive battery that includes 5 tests that assess memory and visual processing speed. Multivariate and univariate analyses of variance and paired t-tests were used to compare ImPACT Pediatric scores from the initial visit to medical clearance. Multivariate and univariate analyses of covariance and multiple linear regression examined factors associated with ImPACT Pediatric performance. RESULTS: Participants demonstrated improved overall performance from the initial visit to the medical clearance visit (F(4, 59)=3.08, p = 0.02, Wilks' Λ = 0.83, ηp2=0.17), with significant improvement in Rapid Processing Speed (F(1, 62)=7.48, p < 0.01, ηp2=0.11). When controlling for age, sex, history of ADHD, and days to clinic, the improvement in overall performance remained significant (F(4, 51)=2.99, p = 0.03, Wilks' Λ = 0.81, ηp2=0.19). Older age was significantly associated with the Rapid Processing composite score at the initial visit (F(4, 59)=5.9, p < 0.001, Adj. R2=0.25) and medical clearance visit (F(4, 59)=3.8, p = 0.008, Adj. R2=0.16), with older children associated with better performance at both time points (Initial visit: B = 8.17, p < 0.001; Medical Clearance: B = 3.62, p = 0.03). CONCLUSION: Our main findings suggest that children aged 5-9 years improved significantly in Rapid Processing on the ImPACT Pediatric from the initial visit to medical clearance. However, no differences were found for the memory components of the ImPACT Pediatric. Older children also performed better on processing speed than younger children. The findings suggest that the processing speed components of ImPACT Pediatric are useful for monitoring improvements in neurocognitive functioning following concussion in children aged 5-9 years, but that age differences need to be considered when interpreting performance.

Behavioral variant of frontotemporal dementia in carriers of biallelic TREM2 variants: cases study.

INTRODUCTION: First reports associated mutations in triggering receptors expressed on myeloid cells 2 (TREM2) with autosomal recessive Nasu-Hakola disease characterized by painful bone cysts and progressive presenile dementia with psychotic symptoms; however, recent TREM2 biallelic rare variants are suggested to be causative also for the behavioral variant of frontotemporal dementia (bvFTD) without bone involvement. MATERIAL AND METHODS: Clinical data of three unrelated bvFTD patients carrying TREM2 biallelic variants were evaluated. All patients underwent neurological, psychiatric, and cognitive evaluation and neuroimaging. A full neuropsychological assessment was performed in two cases. RESULTS: Two patients carried compound heterozygous TREM2 variants, p.R62C and p.T66M, and one carried the homozygous p.D87N variant. Based on all obtained clinical and neuroimaging data, a behavioral variant of frontotemporal dementia was diagnosed in all cases. Their clinical manifestation was typical with neuropsychiatric and cognitive features, without bone abnormalities. CONCLUSIONS: Despite all three subjects partially resembling clinical manifestations of Nasu-Hakola disease with TREM2 mutations, we reveal some distinct features, including age of onset, neuroimaging findings, or disease course.

The Neurofunctional Correlates of Morphosyntactic and Thematic Impairments in Aphasia: A Systematic Review and Meta-analysis.

Lesion-symptom studies in persons with aphasia showed that left temporoparietal damage, but surprisingly not prefrontal damage, correlates with impaired ability to process thematic roles in the comprehension of semantically reversible sentences (The child is hugged by the mother). This result has led to challenge the time-honored view that left prefrontal regions are critical for sentence comprehension. However, most studies focused on thematic role assignment and failed to consider morphosyntactic processes that are also critical for sentence processing. We reviewed and meta-analyzed lesion-symptom studies on the neurofunctional correlates of thematic role assignment and morphosyntactic processing in comprehension and production in persons with aphasia. Following the PRISMA checklist, we selected 43 papers for the review and 27 for the meta-analysis, identifying a set of potential bias risks. Both the review and the meta-analysis confirmed the correlation between thematic role processing and temporoparietal regions but also clearly showed the involvement of prefrontal regions in sentence processing. Exploratory meta-analyses suggested that both thematic role and morphosyntactic processing correlate with left prefrontal and temporoparietal regions, that morphosyntactic processing correlates with prefrontal structures more than with temporoparietal regions, and that thematic role assignment displays the opposite trend. We discuss current limitations in the literature and propose a set of recommendations for clarifying unresolved issues.

Memory-Guided Saccades in Subacute and Chronic Stroke: Secondary Data Analysis of the N-PEP-12 Clinical Study.

BACKGROUND: Ischemic stroke (IS) often leads to cognitive and motor impairments. This study aimed to investigate whether Memory-Guided Saccade Tasks (MGSTs) could be used to assess cognitive function in stroke patients. METHODS: A secondary data analysis was conducted on 62 individuals with supratentorial IS. Eye-tracking metrics from MGST were correlated with established neuropsychological assessments, including the Montreal Cognitive Assessment (MoCA) and Hospital Anxiety and Depression Scale (HADS). RESULTS: Age correlated negatively with memory-guided saccade (MGS) accuracy (ρ = -0.274) and positively with late errors (ρ = 0.327). Higher Montreal Cognitive Assessment (MoCA) scores were associated with faster corrective saccades (ρ = 0.259). Increased anxiety (HADS-A) and depression (HADS-D) levels correlated with higher early error rates (ρ = 0.325 and ρ = 0.311, respectively). The Color Trails Test and Digit Span test performance also correlated with various MGS parameters. CONCLUSIONS: While some correlations were found between cognitive measures and eye-tracking metrics, further research is needed to validate MGST as a tool for cognitive assessment in a more homogenous stroke population.

Comparison of the Diagnostic Accuracy of Five Cognitive Screening Tests for Diagnosing Mild Cognitive Impairment in Patients Consulting for Memory Loss.

Objectives: We aimed to evaluate and compare the diagnostic capacity of five cognitive screening tests for the diagnosis of mild cognitive impairment (MCI) in patients consulting by memory loss. Methods: A cross-sectional study involving 140 participants with a mean age of 74.42 ± 7.60 years, 87 (62.14%) women. Patients were classified as MCI or cognitively unimpaired according to a comprehensive neuropsychological battery. The diagnostic properties of the following screening tests were compared: Mini-Mental State Examination (MMSE), Addenbrooke's Cognitive Examination III (ACE-III) and Mini-Addenbrooke (M-ACE), Memory Impairment Screen (MIS), Montreal Cognitive Assessment (MoCA), and Rowland Universal Dementia Assessment Scale (RUDAS). Results: The area under the curve (AUC) was 0.861 for the ACE-III, 0.867 for M-ACE, 0.791 for MoCA, 0.795 for MMSE, 0.731 for RUDAS, and 0.672 for MIS. For the memory components, the AUC was 0.869 for ACE-III, 0.717 for MMSE, 0.755 for MoCA, and 0.720 for RUDAS. Cronbach's alpha was 0.827 for ACE-III, 0.505 for MMSE, 0.896 for MoCA, and 0.721 for RUDAS. Correlations with Free and Cued Selective Reminding Test were moderate with M-ACE, ACE-III, and MoCA, and moderate for the other tests. The M-ACE showed the best balance between diagnostic capacity and time of administration. Conclusions: ACE-III and its brief version M-ACE showed better diagnostic properties for the diagnosis of MCI than the other screening tests. MoCA and MMSE showed adequate properties, while the diagnostic capacity of MIS and RUDAS was limited.

Evaluating the Effectiveness of the Driving Resumption Assessment in Brain Disorders: Insights From a Retrospective Observational Study.

Objectives For patients with brain disorders, regaining the ability to drive is crucial to their reintegration into society. Despite the existence of numerous assessment methods for determining the ability to resume driving, the most effective approach remains unclear. This study evaluated patients with brain disorders who had received support for driving resumption. We examined the factors influencing the acquisition of driving ability in this specific population. Methods This retrospective observational study was conducted from July 2019 to March 2022. Initially, a desk-based assessment was conducted using neuropsychological tests. Successful candidates subsequently underwent an on-road assessment at an affiliated driving school. Patients who passed both assessments were granted permission to resume driving. The participants were categorized into pass and fail groups based on their assessments, and a comparative analysis was conducted. Age, sex, type of brain disorder, functional independence measures (FIMs), assessments of higher cognitive skills, and physical function test results were evaluated. Results Forty-five patients (average age: 62±13 years) underwent evaluation. Logistic regression analysis for the desk-based assessment identified the Rey-Osterrieth complex figure test (ROCFT) (three-minute delayed recall) as the most influential factor (cutoff value: 21.5 points; sensitivity: 65%; specificity, 72.7%). In the on-road assessment, the 10-m walking test was significantly faster in the passing group than in the failing group (p<0.005). Conclusions We demonstrated that the ROCFT (three-minute delayed recall) was the most effective neuropsychological assessment tool for evaluating driving resumption. The assessment of walking speed may also be able to predict the resumption of driving in patients with brain disorders.

Filling the gap: brief neuropsychological assessment protocol for glioma patients undergoing awake surgeries.

Introduction: The literature lacks a concise neurocognitive test for assessing primary cognitive domains in neuro-oncological patients. This study aims to describe and assess the feasibility of the Ohy-Maldaun Fast Track Cognitive Test (OMFTCT), used to pre- and post-operatively evaluate patients undergoing brain tumor surgery in language eloquent areas. The cognitive diagnosis was used to safely guide intraoperative language assessment. Methods: This is a prospective longitudinal observational clinical study conducted on a cohort of 50 glioma patients eligible for awake craniotomies. The proposed protocol assesses multiple cognitive domains, including language, short-term verbal and visual memories, working memory, praxis, executive functions, and calculation ability. The protocol comprises 10 different subtests, with a maximum score of 50 points, and was applied at three time points: preoperative, immediately postoperative period, and 30 days after surgery. Results: Among the initial 50 patients enrolled, 36 underwent assessment at all three designated time points. The mean age of the patients was 45.3 years, and they presented an average of 15 years of education. The predominant tumor types included Glioblastoma, IDH-wt (44.1%), and diffuse astrocytoma, IDH-mutant (41.2%). The tumors were located in the left temporal lobe (27.8%), followed by the left frontal lobe (25%). The full test had an average application time of 23 min. Conclusion: OMFTCT provided pre- and postoperative assessments of different cognitive domains, enabling more accurate planning of intraoperative language testing. Additionally, recognition of post-operative cognitive impairments played a crucial role in optimizing patient care.

Detection of cerebrospinal fluid biomarkers changes of Alzheimer's disease using a cognitive stress test in persons with subjective cognitive decline and mild cognitive impairment.

Introduction: Timely and accurate diagnosis of the earliest manifestations of Alzheimer's disease (AD) is critically important. Cognitive challenge tests such as the Loewenstein Acevedo Scales for Semantic Interference and Learning (LASSI-L) have shown favorable diagnostic properties in a number of previous investigations using amyloid or FDG PET. However, no studies have examined LASSI-L performance against cerebrospinal fluid biomarkers of AD, which can be affected before the distribution of fibrillar amyloid and other changes that can be observed in brain neuroimaging. Therefore, we aimed to evaluate the relationship between LASSI-L scores and CSF biomarkers and the capacity of the cognitive challenge test to detect the presence of amyloid and tau deposition in patients with subjective cognitive decline and amnestic mild cognitive impairment (MCI). Methods: One hundred and seventy-nine patients consulting for memory loss without functional impairment were enrolled. Patients were examined using comprehensive neuropsychological assessment, the LASSI-L, and cerebrospinal fluid (CSF) biomarkers (Aß1-42/Aß1-40 and ptau181). Means comparisons, correlations, effect sizes, and ROC curves were calculated. Results: LASSI-L scores were significantly associated with CSF biomarkers Aß1-42/Aß1-40 in patients diagnosed with MCI and subjective cognitive decline, especially those scores evaluating the capacity to recover from proactive semantic interference effects and delayed recall. A logistic regression model for the entire sample including LASSI-L and age showed an accuracy of 0.749 and an area under the curve of 0.785 to detect abnormal amyloid deposition. Conclusion: Our study supports the biological validity of the LASSI-L and its semantic interference paradigm in the context of the early stages of AD. These findings emphasize the utility and the convenience of including sensitive cognitive challenge tests in the assessment of patients with suspicion of early stages of AD.

Is language translation enough in cross-cultural neuropsychological assessments of patients from Latin America?

OBJECTIVE: The purpose of this review was to highlight the need to consider factors other than language when adapting tests across cultural groups and to offer a list of tests that have been adapted for use among patients from or descended from Latin American Countries. Despite efforts in the field through publications and workshops, the authors were aware of continued errors in cross-cultural assessment of these patients, resulting in misdiagnosis and unintentional inequitable care. Thus, we sought to reinforce the existing literature. METHOD: We reviewed the literature pertaining to cross-cultural adaptation of neuropsychological measures. Relevant papers were identified by our institution's Academic Enhanced Search Option (AcESO) Database, PubMed, and Google Scholar. RESULTS: 102 papers, articles, and other published literature were reviewed describing issues related to the adaptation of tests for groups originally from or descended from Latin American Countries residing in the United States. CONCLUSIONS: It is imperative that tests be appropriately developed or adapted for the target population with appropriate normative data available, and ideally administered by a fluent speaker trained in assessment. Inappropriate use of tests not adapted for a particular patient's language and country of origin can result in misdiagnosis, potentially resulting in harm to the individual.

Assessment of phonemic verbal fluency in Portuguese patients with multiple sclerosis.

BACKGROUND: Executive dysfunction occurs in 15% to 20% of multiple sclerosis (MS) patients and verbal fluency tests are frequently used to assess this deficit. The Word List Generation (WLG) is one of the most used measures in MS. This study aims to compare the performance of WLG of MS patients and healthy controls and to analyze the influence of clinical and demographic factors on the performance of MS patients. METHODS: One hundred and nine MS patients and an age- and gender-matched group of 138 healthy controls were evaluated with WLG Portuguese version, as well as other tests from the Brief Repeatable Battery of Neuropsychological Tests (BRBN-T), subtests from WAIS, a phonemic fluency test (M, R, and P), and measures of psychological symptomatology and cognitive fatigue. The MS group (70.6% females) was mainly diagnosed with RRMS (89.2%). RESULTS: The MS group performed significantly lower than healthy controls on the WLG. In the MS group, this performance was significantly correlated with the level of education. Significant differences were found between the two groups regarding cognitive fatigue, with MS patients reporting higher levels than healthy controls. However, this variable was not related to the performance on the WLG for MS patients. CONCLUSIONS: This study suggests that MS is associated with large levels of cognitive decline on the phonemic verbal fluency tests. These results are consistent with other studies and highlight the importance of verbal fluency and cognitive speed measures in the neuropsychological assessment of MS. Deficits on this task seem to be highly related to the level of education of the patient rather than other demographic and clinical factors.

Providing a brief corrective statement does not improve test performance in patients invalidating testing: A multisite, single-blind randomized controlled trial.

Objective: Performance below the actual abilities of the examinee can be measured using performance validity tests (PVTs). PVT failure negatively impacts the quality of the neuropsychological assessment. In our study, we addressed this issue by providing a brief corrective statement regarding invalidity to improve test-taking behavior. Methods: This study is a multisite single-blind randomized controlled trial in a consecutive sample of clinically referred adult patients (N = 196) in a general hospital setting. Patients who failed a PVT (n = 71) were randomly allocated to a corrective statement approach (CS; n = 39), in which a brief verbal corrective statement was given by the technician, or received no corrective statement upon indications of invalid performance (NO-CS; n = 32). Both groups (CS and NO-CS) were provided with the same subsequently repeated and newly administered tests. Results: There were no group (CS vs. NO-CS) differences on both the repeated and single-administered PVTs and standard cognitive tests. Furthermore, invalid performing participants benefited significantly less from the repeated test administration compared to the valid performing group. Conclusions: Our study found that a brief corrective within-session statement, to address PVT failure and improve test-taking behavior, did not improve consequent test performance. These results suggest limited value of a brief verbal corrective statement to influence performance below best of capabilities. It highlights the need for more research to identify more effective approaches that can enhance patients test-taking behavior. Ultimately, such efforts are critical in ensuring accurate diagnosis and effective treatment recommendations for patients.

Improved readability in written neurodevelopmental reports by five writing rules.

The purpose of a neuropsychological assessment is to describe a child's difficulties and strengths to enable treatments and contextual adjustments. Typically, the assessment is summarized in the form of a written clinical report. However, such texts have been criticized for being too difficult for parents and teachers to read and comprehend. The purpose of this pre-registered and randomized controlled study was to evaluate five writing rules to improve readability and accessibility in clinical reports: to structure the text with functional domains, exemplify cognitive tasks with examples from daily life, use examples from the daily life of the child, avoid jargon, and to write shorter sentences. We created two separate reports based on the same assessment information of a hypothetical child: one "standard" report, and one where the five writing rules were applied. One hundred teacher students at a teacher education program were randomized to read one of the reports, and then rated readability and answered a comprehension quiz. Results showed that the five writing rules led to improved ratings of readability, and helped readers recall more information immediately afterward. Effects were medium to large. Future studies need to investigate whether the findings generalize to parents and other potential readers. Additionally, future work should address how psychologists can be taught to improve their writing through writing guidelines. Clinical trial registration: https://aspredicted.org/ac96p.pdf.

What traditional neuropsychological assessment got wrong about mild traumatic brain injury. II: limitations in test development, research design, statistical and psychometric issues.

PRIMARY OBJECTIVE: This is Part II of a four-part opinion review on traditional neuropsychological assessment methods and findings associated with mild traumatic brain injury (mTBI). This Part II review focuses on historical, psychometric and statistical issues involving traditional neuropsychological methods that have been used in neuropsychological outcome studies of mTBI, but demonstrates the critical limitations of traditional methods. RESEARCH DESIGN: This is an opinion review. METHODS AND PROCEDURES: Traditional neuropsychological tests are dated and lack specificity in evaluating such a heterogenous and complex injury as occurs with mTBI. MAIN OUTCOME AND RESULTS: In this review, we demonstrate traditional neuropsychological methods were never developed as standalone measures for detecting subtle changes in neurocognitive or neurobehavioral functioning and likewise, never designed to address the multifaceted issues related to underlying mTBI neuropathology symptom burden from having sustained a concussive brain injury. CONCLUSIONS: For neuropsychological assessment to continue to contribute to clinical practice and outcome literature involving mTBI, major innovative changes are needed that will likely require technological advances of novel assessment techniques more specifically directed to evaluating the mTBI patient. These will be discussed in Part IV.

Exploring the Neuropsychological Correlates of Swallowing Disorders in People with Parkinson's Disease: a Cross-Sectional Study.

Around 80% of persons with Parkinson's disease (PD) present symptoms of dysphagia. Although cognitive impairment may contribute to dysphagia, few studies have investigated the association between the PD neuropsychological profile and objective measures of swallowing dysfunction. Since the swallowing function comprises involuntary but also voluntary actions, we hypothesize that specific measures of attention and executive functions can be underlined in PD-related dysphagia. Therefore, the aim of this study was to extensively investigate the correlation and the relationship between attentive and executive functions and safety/efficiency of pharyngeal phase of swallowing in people with PD. All participants received a fiberoptic endoscopic evaluation of swallowing and were evaluated using the Penetration Aspiration Scale (PAS); the Yale Pharyngeal Residue Severity Rating Scale (IT-YPRSRS), and the Functional Oral Intake Scale (FOIS-IT). Participants also underwent a neuropsychological assessment covering global cognitive status, attention, and frontal executive functions. Correlations and associations between neuropsychological measures and swallowing components were calculated. Twenty-one participants with PD (mean age 69.38 ± 6.58 years, mean disease duration 8.38 ± 5.31 years; mean MDS-UPDRS III 43.95 ± 24.18) completed all evaluations. The most significant correlations were found between attentive functions (i.e., Stroop Time), and executive functions (i.e., Raven's Progressive Matrices, Digit Backward and Semantic Fluency), and FOIS-IT, PAS, and IT-YPRSRS sinuses and valleculae. These associations were not influenced by disease duration. These results suggest that a dysfunction to attentional processes and/or to executive functions can contribute to penetration and the presence of pharyngeal residue in participants with middle-stage PD.
