Naming Ability Research Articles

Auditory naming is impaired in posterior cortical atrophy and early-onset Alzheimer's disease.

Visual naming ability reflects semantic memory retrieval and is a hallmark deficit of Alzheimer's disease (AD). Naming impairment is most prominently observed in the late-onset amnestic and logopenic variant Primary Progressive Aphasia (lvPPA) syndromes. However, little is known about how other patients across the atypical AD syndromic spectrum perform on tests of auditory naming, particularly those with primary visuospatial deficits (Posterior Cortical Atrophy; PCA) and early onset (EOAD) syndromes. Auditory naming tests may be of particular relevance to more accurately measuring anomia in PCA syndrome and in others with visual perceptual deficits. Forty-six patients with biomarker-confirmed AD (16 PCA, 12 lvPPA, 18 multi-domain EOAD), at the stage of mild cognitive impairment or mild dementia, were administered the Auditory Naming Test (ANT). Performance differences between groups were evaluated using one-way ANOVA and post-hoc t-tests. Correlation analyses were used to examine ANT performance in relation to measures of working memory and word retrieval to elucidate cognitive mechanisms underlying word retrieval deficits. Whole-cortex general linear models were generated to determine the relationship between ANT performance and cortical atrophy. Based on published cutoffs, out of a total possible score of 50 on the ANT, 56% of PCA patients (mean score = 45.3), 83% of EOAD patients (mean = 39.2), and 83% of lvPPA patients (mean = 29.8) were impaired. Total uncued ANT performance differed across groups, with lvPPA performing most poorly, followed by EOAD, and then PCA. ANT performance was still impaired in lvPPA and EOAD after cuing, while performance in PCA patients improved to the normal range with phonemic cues. ANT performance was also directly correlated with measures of verbal fluency and working memory, and was associated with cortical atrophy in a circumscribed semantic language network. Auditory confrontation naming is impaired across the syndromic spectrum of AD including in PCA and EOAD, and is likely related to auditory-verbal working memory and verbal fluency which represent the nexus of language and executive functions. The left-lateralized semantic language network was implicated in ANT performance. Auditory naming, in the absence of a visual perceptual demand, may be particularly sensitive to measuring naming deficits in PCA.

Language, cognitive, and speech in noise perception abilities of children with cochlear ımplants: a comparative analysis by implantation period and bilateral versus unilateral cochlear implants

PurposeThe purpose of this study was to compare the language, cognitive, and speech in noise (SiN) perception abilities of children with cochlear implants (CIs) to those of their peers with NH by grouping them according to their implantation period (12–18 months/19–24 months) and unilateral/bilateral CI use.MethodsThe sample comprised 50 children with cochlear implants (CIs) and 20 children with normal hearing (NH), ages 6–9 years. Children’s language, cognitive, and speech in noise (SiN) perception skills were assessed.ResultsChildren with CIs between 12 and 18 months and 19 and 24 months performed more poorly than children with NH on language, verbal memory (VM), verbal-short-term memory (V-STM), verbal working memory (V-WM), rapid naming, and speech in noise (SiN) perception abilities measures (p < 0.001). In addition, children with CIs between 19 and 24 months performed worse on rapid naming and V-WM tasks than children with CIs between 12 and 18 months (p < 0.017). Children with unilateral and bilateral CI performed more poorly than children with NH on language, VM, V-STM, V-WM, rapid naming, and SiN perception abilities assessments (p < 0.001). Additionally children with unilateral CI users performed poorly than children with bilateral CI users on SiN perception (p < 0.017).ConclusionsIn children with congenital hearing loss (CHL), cochlear implantation between 12 and 18 months or sequential bilateral implantation is not sufficient for these children to perform like their NH peers in language, cognitive, and SiN perception abilities. In addition, intervention approaches should focus not only on increasing language skills, but also on cognitive abilities.

Construction and Validation of Zoomorphic Naming Ability Test in Zoology

Zoology is the branch of biology concerned with the study animals and animal kingdom. It is also known as animal biology. The study zoology includes the interaction of animal kingdom in their ecosystems such as classification, habits, structure, embryology, distribution, evolution, and extinct species. Zoology is the division of biology that deals with the animals kingdom. It is the scientific study related to construct and validate the tool to measure the higher secondary science stream students in Zoomorphic naming ability it means that the science of naming, describing and classify organism and includes all animals and microorganism of the world. Therefore, this work is an attempt to construct and validate a tool for assessing the zoomorphic naming ability of higher secondary students who are studying in science stream.

24 hour rest‐activity rhythms and cognition in community dwelling older adults

AbstractBackgroundCognitive decline associated with aging is a growing public health concern as individuals are living longer with chronic medical conditions. Rest activity rhythm (RAR) describes the pattern of physical activity and sleep period in 24 hours. Compared with younger people, older adults are more likely to maintain a sedentary lifestyle with altered RAR. Although there is no doubt that physical activity plays a vital role in health outcomes, little is known about how RAR is linked to cognitive functioning in late life. This study investigated the association between RAR and cognitive performance among older adults.MethodSixty community dwelling older adults aged 70±7.3 years (mean ± standard deviation) wore Phillips actigraphy spectrum plus 2 for two weeks. RAR parameters were analyzed using cosinor approach, such as amplitude (difference between the peak and lowest activity levels), mesor (mean activity level), pseudo‐F‐statistic (the robustness of RAR), and acrophase (peak activity time). A comprehensive neuropsychological battery was used to assess cognition (i.e., Brief Visuospatial Memory Test – Revised (BVMT‐R), California Verbal Learning Test – II, Boston Naming Test, Wechsler Adult Intelligence Scale‐IV Coding, and Trail Making Test A and B). Multiple linear regression models were built to explore associations between different RAR measures and each cognitive task adjusting for age, gender, and years of education.ResultWe found positive associations between RAR amplitude (p = 0.01), mesor (p = 0.008), acrophase (p = 0.006), pseudo F‐statistic (p = 0.002) and visual memory (BVMT‐R). Similarly, positive associations were found between amplitude (p = 0.006), mesor (p = 0.005), acrophase (p = 0.005), pseudo F‐statistic (p = 0.002) and psychomotor processing speed (Coding). Greater pseudo‐F statistics were associated with stronger performance on naming (BNT); p = 0.03). No association was found between RAR and other cognitive tasks.ConclusionsOur findings provide evidence that some RAR characteristics are associated with cognitive performance among older adults, particularly visual memory, psychomotor processing speed, and naming ability. Further research should be undertaken using a large and diverse sample, prospective design, and inclusion of potentially confounding variables to confirm those associations.

Efficacy of smartphone application-based multi-domain cognitive training in older adults without dementia

BackgroundAs the population ages and the prevalence of dementia increases, there is a growing emphasis on the importance of cognitive training to prevent dementia. A smartphone application-based cognitive training software program, BeauBrain Trainer (BBT), has been developed to provide better access to cognitive training for older adults. Numerous studies have revealed the effectiveness of cognitive training using a cognitive assessment tool. However, relatively few studies have evaluated brain activation using brain imaging as a result of improved cognitive function.MethodsAll participants were required to download the BBT, an Android-based application for cognitive training, onto their own smartphone or tablet computer and to engage in cognitive training at home. Older adults without dementia were enrolled in this study, including 51 participants in the intervention group and 50 participants in the control group. The BBT comprised a set of 12 cognitive tasks, including two tasks in each of the following six cognitive domains: attention, language, calculation, visuospatial function, memory, and frontal/executive function. Each cognitive task was divided into four blocks based on its level of difficulty. A 16-week cognitive training was designed to carry out cognitive tasks using a total of 48 blocks (12 tasks × 4 levels) for at least 1.5 h per day, 5 days per week. All participants in the intervention group were given BBT tasks that gradually increased in difficulty level, which they submitted through a smartphone application daily for 16 weeks. The researchers monitored the participants’ task performance records on the website and encouraged participants to engage in cognitive training through regular contact. This study was conducted to investigate the improvement in cognitive function and the activation pattern of the frontal cortex in older adults participating in smartphone application-based cognitive training. The cognitive assessment tool was the BeauBrain cognitive screening test (CST), a tablet-based computerized cognitive screening test. The activation pattern of the frontal cortex was measured using functional near-infrared spectroscopy (fNIRS). Additionally, this study aimed to determine the positive effects of cognitive training on everyday functioning and psychological states using a questionnaire.ResultsOf 101 participants, 85 older adults without dementia (84.1%) who completed the study protocol were included in the statistical analysis. There were 41 participants (80.3%) in the intervention group and 44 participants (88.0%) in the control group. A two-way repeated-measures analysis of variance (ANOVA) was used to compare the cognitive scores over a 16-week period between the intervention and control groups. According to the CST results, the intervention group exhibited a statistically significant increase in the language subtest scores, specifically the phonemic word fluency test, compared to those of the control group. The fNIRS results revealed greater activation in the dorsolateral prefrontal cortex during the STROOP incongruent task in the intervention group than did the control group. However, the effectiveness of cognitive training was not observed across a variety of rating scales, including everyday functioning, depression, self-efficacy, attention, and subjective memory complaints.ConclusionThis study revealed that a smartphone-based cognitive training application led to improvements in phonemic generative naming ability and activation of the prefrontal cortex in older adults without dementia. This study is meaningful because it confirmed that cognitive training is partially effective in enhancing frontal lobe function. It also provided information on the brain mechanisms related to the effects of cognitive training using fNIRS.

Long-term effects of transcranial direct current stimulation (tDCS) combined with speech language therapy (SLT) on post-stroke aphasia patients: A systematic review and network meta-analysis of randomized controlled trials.

Transcranial direct current stimulation (tDCS) is a noninvasive neuromodulation tool for improving language performance in patients with aphasia after stroke. However, it remains unclear whether it has long-term effects. After consulting a large number of relevant studies, it was found that there are no definitive conclusions about the long-term effects of tDCS on post-stroke aphasia patients. To determine whether tDCS has long-term effects on post-stroke aphasia patients (PAPs) and which type of tDCS has the most beneficial treatment effects on language performance (especially naming ability). A network meta-analysis was conducted by searching for randomized controlled trials (RCTs) published until April 2023 in the following databases: Web of Science, Embase, Medline (from OVID and PubMed), PsycInfo and PsycARTICLES (from OVID). We only included RCTs published in English. PAPs treated by tDCS combined with speech-language therapy were selected. Sham tDCS was the control group. Naming ability or other language performance must be assessed at follow-up states. Two reviewers independently used checklists to assess the primary outcome (the long-term effects on naming ability) and the secondary outcome (other language performance, such as communication). Cochrane Collaboration guidelines were used to assess the risk of bias. Seven studies with 249 patients were included for data synthesis. For primary outcomes (naming nous), there was no obvious evidence to show a difference between interventions (C-tDCS vs. S-tDCS SMD = 0.06, 95% CI = -1.01, 1.12; A-tDCS vs. S-tDCS SMD = 0.00, 95% CI = -0.66, 0.65; D-tDCS vs. S-tDCS SMD = 0.77, 95% CI = -0.71, 2.24; A-tDCS vs. C-tDCS SMD = -0.06, 95% CI = -1.31,1.19; D-tDCS vs. C-tDCS SMD = 0.71, 95% CI = -1.11,2.53; D-tDCS vs. A-tDCS SMD = 0.77, 95% CI = -0.84, 2.39). In addition, no evidence showed differences in communication ability (C-tDCS vs. S-tDCS SMD = 0.08 95% CI = -1.77, 1.92; A-tDCS vs. S-tDCS SMD = 1.23 95% CI = -1.89, 4.34; D-tDCS vs. S-tDCS SMD = 0.70; 95% CI = -1.93, 3.34; A-tDCS vs. C-tDCS SMD = 1.15 95% CI = -2.48, 4.77; D-tDCS vs. C-tDCS SMD = 0.62 95% CI = -2.59, 3.84; D-tDCS vs. A-tDCS SMD = -0.52 95% CI = -4.60, 3.56). It seems that tDCS has no long-term effects on post-stroke aphasia patients in naming nouns and communication in terms of the results of our network meta-analysis. However, the results should be interpreted with caution. In the future, more RCTs with long follow-up times should be included in the research to conduct subgroup or meta-regression analyses to obtain a sufficient effect size.

72 Boston Naming Test Performance Improves with Increasing Age: What's Wrong with this Picture?

Objective:As word finding or "naming" impairment is a symptom of multiple neurological conditions, naming assessment is an integral component of most neuropsychological evaluations. For decades, the Boston Naming Test (BNT) has been, and remains, the most widely used measure of naming. Although it has been shown that naming is generally stable from young adulthood through middle age, we have observed, clinically, that young adults tend to have greater difficulty on the BNT than older adults. Considering that the BNT was developed more than 50 years ago, and that language and culture change over time, we hypothesized that 1) increasing age would be associated with stronger performance on the BNT, whereas 2) there would be no association between age and naming performance on more recently developed naming measures.Participants and Methods:Participants were healthy adults who served as normative subjects in the revision study of the Auditory (ANT) and Visual Naming (VNT) Tests. Due to known effects of education level on BNT performance, we excluded those with less than 16 years of education, targeting young adults through middle age, resulting in 118 adults, 20 through 50 years of age (mean age: 32.9 ± 9.2 years; mean education: 16.8 ± 1.2 years; mean FSIQ: 106.0 ± 12. 6). All participants were native English speakers or learned English by age 5 and were fully educated in English. Untimed accuracy (i.e., response within 20 seconds) is the standard performance measure for the BNT; the ANT and VNT additionally include tip-of-the-tongue (TOT) scores, which incorporate response time and reliance on phonemic cueing (TOT score = number of items named in &gt; 2 seconds but &lt; 20 seconds, plus items named correctly after 20 seconds, following a phonemic cue). Pearson correlations examined the relation between age and naming performance on the BNT, ANT and VNT.Results:Pearson correlations revealed a small but significant, positive correlation between age and BNT performance (r =.22, p = .017), yet no correlation between age and performance on the ANT (ANT Accuracy: r = .05, p=.60, ANT-TOT: r = -.14, p = .12) or VNT (VNT Accuracy: r = .04, p=.67, VNT-TOT; r = -.03, p = .72).Conclusions:In this sample of healthy adults, naming performance improved with increasing age on the BNT; however, while vocabulary knowledge may broaden, naming efficiency should not improve with age. By contrast, we found no relation between age and naming performance on the more recently developed ANT and VNT. Results underscore the need to revise test stimuli on verbal measures, particularly those that assess naming, and suggest caution in interpreting BNT performance in young adults, as poor BNT performance might not accurately represent their true naming ability.

Repetition Priming Treatment for Anomia: Effects of Single- and Multiple-Exemplar Protocols.

Repetition priming can lead to improved naming ability in people with aphasia, but concerns have arisen from prior research about using only a single picture exemplar for each target. Specifically, it is unclear whether the observed improvements were due to learning simple correspondences between particular words and pictures rather than changes at a deeper level of lexical-semantic processing. In addition, implications for generalization after training with single exemplars were unclear. This study replicated and extended previous work to address these questions. Five participants with chronic aphasia participated in this repeated-measures design study, which repeatedly paired words and pictures with no feedback provided. Two participants engaged in a single-exemplar condition, with a single picture exemplar of each target used for every presentation of that target. The remaining three participants engaged in a multiple-exemplar condition, with several different pictures used for each target. Half of these targets used training pictures during naming probes, whereas half did not. Primed items led to greater improvements in naming than items that were practiced but not primed. The data indicate that improvements may extend beyond stimulus-specific correspondences. Maintenance and generalization effects were mixed. These data provide further support for the efficacy of repetition priming treatment for anomia. Implications and future directions are discussed.

Autophagy markers, cognitive deficits and depressive symptoms in Parkinson's disease.

Depressive symptoms are common in Parkinson's disease (PD). The relationships between autophagy and PD or depression have been documented. However, no studies explored the role of autophagy markers associated with depressive symptoms in PD. Our study aimed to investigate the relationships between autophagy markers, cognitive impairments and depressive symptoms in PD patients.A total of 163 PD patients aged 50-80years were recruited. Plasma concentrations of autophagy markers (LC3-I, LC3-II and p62/SQSTM1) and glycolipid parameters were measured. Depressive symptoms, cognitive impairments, and motor function were assessed using the Hamilton Depression Rating Scale-17 (HAMD-17), the Montreal Cognitive Assessment (MoCA), and the Movement Disorders Society Unified Parkinson's Rating Scale Part III (MDS-UPDRS-III), respectively.There were no significant differences between depressed and non-depressed PD patients for LC3-I, LC3-II, LC3-II/LC3-I and p62/SQSTM1. After controlling confounding variables, LC3-II/LC3-I showed an independent relationship with depressive symptoms in PD patients (Beta = 10.082, t = 2.483, p = 0.014). Moreover, in depressive PD patients, p62/SQSTM1 was associated with MoCA score (Beta = -0.002, t = -2.380, p = 0.020); Further, p62/SQSTM1 was related to naming ability; in addition, p62/SQSTM1 was independently associated with delayed recall (Beta = -0.001, t = -2.452, p = 0.017).LC3-II/LC3-I was related to depressive symptoms in PD patients. In depressive PD patients, p62/SQSTM1 was associated with cognitive function, especially naming ability and delayed recall.

Effects of Transcranial Direct Current Stimulation on Graph Naming Function and Brain Connectivity in Postinfarction Aphasia Patients: An fMRI Study

Introduction: The study aimed to investigate the mechanisms of impairment and recovery in graph naming functions among patients with aphasia due to cerebral infarction. Specifically, the study compared immediate effects of transcranial direct current stimulation (tDCS) treatment in patients at different stages postinfarction: the acute phase (AP) and the recovery period (RP). Methods: Twenty-eight patients were selected, consisting of 16 in the AP and 12 in the RP, along with 18 healthy controls. Both patient groups underwent 2 weeks of tDCS treatment. Posttreatment changes in functional connectivity (FC) within language-related brain regions, as well as in graph naming abilities, were assessed in both patient groups. Results: Both AP and RP groups exhibited significant improvements in graph naming ability following tDCS treatment. Compared to healthy controls, patients showed decreased FC in multiple brain regions of both hemispheres, particularly in the dominant hemisphere. Posttreatment assessments revealed significant increases in FC within the bilateral frontotemporal lobes for both AP and RP groups, and within the bilateral temporo-occipital regions for the AP group. Moreover, the RP group demonstrated decreased FC in the left temporal lobe posttreatment, which had shown increased FC pre-treatment. Conclusions: This study suggests that tDCS can effectively enhance graph naming functions in patients with postinfarction aphasia. The therapeutic effects appear to be mediated by enhancing FC within bilateral frontotemporal lobes.

Exploring the impact of the COVID-19 lockdown on pre-reading skills among Portuguese children

IntroductionAlthough it could be expected that the COVID-19 pandemic impacted preschool children’s abilities associated with later reading skills, research has not yet addressed the topic. Our study focused on the impact of the pandemic on phonological awareness (PA) and rapid automatized naming (RAN) abilities that have been shown to reliably predict later reading skills.MethodsA cohort of 82 typically developing European Portuguese children (mean age = 64.5 months, SD = 3.47), enrolled in their last year of preschool and dramatically affected by COVID-19 lockdowns, were assessed for PA and RAN skills.ResultsCompared to pre-pandemic normative data, our findings revealed lower average scores on the PA subtest (t = −10.85; p &amp;lt; 0.001; d = 1.62) and comparable average scores on the RAN task. A year later, the same group of children still exhibited lower scores on PA skills (t = 2.87; p = 0.005; d = 0.41). Furthermore, their word reading performance was also below the expected according to the normative pre-pandemic dataset (t = −2.69; p = 0.008; d = 0.29). A further comparison between the preschoolers affected by the pandemic and a post-pandemic cohort from the same school setting (N = 25; mean age = 72.08 months, SD = 3.30) highlighted that the pandemic cohort had lower PA average scores than their post-pandemic peers (t = 12.27; p &amp;lt; 0.001; d = 2.66).DiscussionThese findings underscore the enduring impact of disrupted learning environments on pre-reading abilities among preschoolers. Consequently, they contribute to further the understanding of the effects of the pandemic on the learning progress of young children.

Validity and reliability of the Thai Adaptation of Naming Test-Revised (TANT-Revised)

Background: The Thai Adaptation of Naming Test (TANT) is useful for assessing naming ability among Thais with naming deficits. However, the TANT was developed in 2004, meaning some words have become less common. Consequently, the TANT was revised for modernity and suitability for the current Thai cultural context and to measure the psychological properties. Objectives: To assess the validity and reliability of the Thai Adaptation of Naming Test-Revised (TANT-Revised). Materials and methods: The TANT was revised by adjusting certain items for suitability to the current Thai cultural context, consisting of 2 parts: Pictures of words and semantic cues. Subsequently, the TANT-Revised was assessed for content validity index (CVI), content validity for the item (I-CVI), and content validity Index for scale (S-CVI) test by five expert speech-language pathologists (SLPs). Afterward, the TANT-Revised was examined for test-retest reliability by intraclass correlation coefficient (ICC) in an aphasia group and a normal group, with 13 people per group. Results: The results of testing for the validity of TANT-Revised by expert SLPs revealed that the validity for pictures (CVI = 0.96, S-CVI = 0.99, and I-CVI = 1) and semantic cues (CVI = 0.95, S-CVI = 0.99, and I-CVI = 1) have high reliability in the normal group at 0.79 and the aphasia group at 0.96. Conclusion: This study assessed the psychological properties of the TANT-Revised instrument used to test naming ability. The validity of the revision test was high, and the TANT-Revised was deemed acceptable by experts. In addition, the test-retest reliability of TANT-Revised was high in both the normal and aphasia groups, implying the TANT-Revised is an efficient instrument for confrontation naming ability. However, this study was a preliminary test revision, and insufficient norm data and factors are affecting the test score.

Age of epilepsy onset as modulating factor for naming deficit after epilepsy surgery: a voxel-based lesion-symptom mapping study

Age at onset of epilepsy is an important predictor of deterioration in naming ability following epilepsy surgery. In 141 patients with left hemispheric epilepsy and language dominance who received epilepsy surgery at the Epilepsy Centre Erlangen, naming of objects (Boston naming test, BNT) was assessed preoperatively and 6 months postoperatively. Surgical lesions were plotted on postoperative MRI and normalized for statistical analysis using voxel-based lesion-symptom mapping (VBLSM). The correlation between lesion and presence of postoperative naming deterioration was examined varying the considered age range of epilepsy onsets. The VBLSM analysis showed that volumes of cortex areas in the left temporal lobe, which were associated with postoperative decline of naming, increased with each year of later epilepsy onset. In patients with later onset, an increasing left posterior temporobasal area was significantly associated with a postoperative deficit when included in the resection. For late epilepsy onset, the temporomesial expansion also included the left hippocampus. The results underline that early onset of epilepsy is a good prognostic factor for unchanged postoperative naming ability following epilepsy surgery. For later age of epilepsy onset, the extent of the area at risk of postoperative naming deficit at 6 months after surgery included an increasing left temporobasal area which finally also comprised the hippocampus.

Patterns in fish naming ability in two fishing communities of Myanmar

BackgroundTo date, there is little reliable information on the fish names used by two fishing communities of Myanmar, namely Intha (Inle Lake) and Rakhine (Bay of Bengal). Moreover, there have been no systematic studies on the distribution of fish-related traditional knowledge in these two communities. As there can be high levels of intra-community variation in traditional ecological knowledge, it is important to investigate this variation along the lines of key social variables.MethodsFieldwork was carried out in both communities and involved the presentation of visual stimuli (colour pictures of locally relevant fish species) to respondents, and asking for a name in the local language. The stimuli consisted of 43 and 218 fish species for Intha and Rakhine, respectively. The responses were analysed in terms of respondent age and occupation for both communities, plus village location for Intha and gender whenever both genders were represented in a sufficiently large number in the sample.ResultsFish name lists were generated for both languages, taking into account lexical variation, as well as the number of people able to name each fish. The two communities differed markedly in the way fish knowledge was distributed. Overall, younger Intha knew fewer fish names, but there was little to no difference in fish knowledge among the Intha on the basis of occupation, location or gender. In contrast, the differences were very marked among Rakhine respondents.ConclusionsThe reduced fish knowledge of younger Intha may be ascribed to environmental disturbances that have caused many fish to go locally extinct. The otherwise homogenous distribution of fish knowledge in the Intha community may be due to the small number of species that people are required to learn. This idea needs to be tested with a larger sample of respondents. Among the Rakhine, a number of factors are responsible for the observed variation; these include a steep learning curve among younger fishermen, the difference in fish species encountered by fishermen and sellers, highly variable dietary preferences among the general populace and differing gender roles in the context of market visits. The authors are in full agreement with previous research that advocates a variationist approach to the study of traditional ecological knowledge.

Late-onset epilepsy with cognitive symptoms: Comparison of cognitive and imaging profiles with probable Alzheimer’s disease

ObjectiveWe aimed to (i) compare the clinical, neuropsychological, and neuroimaging characteristics of unprovoked late-onset epilepsy (LOE) patients with cognitive symptoms against probable Alzheimer’s disease (AD) patients; (ii) clarify how neurodegeneration and other processes could be implicated in the cognitive symptoms of unprovoked LOE patients; and (iii) characterize the longitudinal trajectory of unprovoked LOE patients with cognitive symptoms. MethodsTwenty-six unprovoked LOE patients with cognitive symptoms and 26 probable AD were retrospectively recruited from epilepsy and memory clinics at a single tertiary referral center. The patients underwent comprehensive clinical, neuropsychological, and 18Fluorodeoxyglucose PET-CT assessments. All LOE patients had clinical follow-up and a subset of 17 patients had repeat neuropsychological assessments. ResultsAt baseline, 18% of LOE patients with cognitive symptoms had dementia-range cognitive impairment and one received a diagnosis of probable AD. Compared with the probable AD group, the LOE group did not perform significantly better in global measures of cognition (total ACE-III), neuropsychological tests for fluency, working memory, language, attention, or executive function, but performed better in naming, memory, and visuospatial ability. The commonest patterns of cognitive impairment in the LOE group were frontal and left temporal, whereas all AD patients exhibited parietotemporal patterns. The AD group had more 18Fluorodeoxyglucose PET-CT hypometabolism in the parietal and occipital, but not the temporal and frontal lobes. During the 3.0 ± 3.2 years follow-up, improved seizure frequency in the LOE group covaried with improved total ACE-III score, there was no further conversion to probable AD and no group-level cognitive decline. ConclusionUnprovoked LOE patients with cognitive symptoms had varying severities of cognitive impairment, and different patterns of cognitive and imaging abnormalities compared with AD patients. They were rarely diagnosed with probable AD at presentation or follow-up. Cognitive outcome in LOE may be related to seizure control. Cerebral small vessel disease may play a role in LOE-associated cognitive impairment.

A literacy-related color-specific deficit in rapid automatized naming: Evidence from neurotypical completely illiterate and literate adults.

There is a robust positive relationship between reading skills and the time to name aloud an array of letters, digits, objects, or colors as quickly as possible. A convincing and complete explanation for the direction and locus of this association remains, however, elusive. In this study, we investigated rapid automatized naming (RAN) of everyday objects and basic color patches in neurotypical illiterate and literate adults. Literacy acquisition and education enhanced RAN performance for both conceptual categories but this advantage was much larger for (abstract) colors than everyday objects. This result suggests that (a) literacy/education may be causal for serial rapid naming ability of non-alphanumeric items and (b) differences in the lexical quality of conceptual representations can underlie the reading-related differential RAN performance.

Which language is more affected in bilinguals with Alzheimer's disease? Diagnostic sensitivity of the Multilingual Naming Test.

This study examined the joint consequences of bilingualism and Alzheimer's disease (AD) for picture naming ability to determine which language is more affected by AD and what scoring methods best distinguish patients from controls. Sixty-five Spanish-English bilinguals including 26 with dementia and 39 controls with equivalent age, education, and bilingual proficiency level, were tested on the Multilingual Naming Test (Gollan et al., 2012). Bilinguals with AD named fewer pictures than controls, and overall AD seemed to affect both languages about equally, but exploratory analyses suggested that this varied with item difficulty. In the dominant language difficult items exhibited a larger effect of AD than easy items (which were at ceiling for both patients and controls), whereas in the nondominant language items of all difficulty levels were about equally affected by AD. An "either-language" scoring procedure (that counted items as correct if produced only in one of the two languages) increased naming scores especially in balanced bilinguals, and to an equal extent in patients and controls. Receiver Operating Characteristic analyses revealed that dominant language and either-language naming scores classified bilinguals as patients versus controls equally well and adding nondominant language scores did not improve diagnostic sensitivity. Testing primarily or exclusively in the dominant language is best for detecting AD naming impairments in bilinguals. However, AD affects the ability to access names in both languages, possibly for different reasons, and simple descriptions of language decline as "parallel" or "asymmetrical" (i.e., AD affecting one language more than the other) may be misleading in terms of the theoretical implications for bilingual language processing.

Frequency, pattern and predictors of cognitive impairments in patients with Parkinson's disease using the Community Screening Instrument for Dementia.

Parkinson's disease (PD) is a chronic neurodegenerative disorder complicated by cognitive dysfunctions which are associated with increased caregiver burden, pressure on community health facilities, and mortality in affected patients. Most of the data concerning cognitive dysfunctions in PD are from studies conducted in Europe and North America, but there is paucity of data from Sub-Saharan Africa. The objective of this study is to determine the frequency, pattern and predictors of cognitive impairments amongst patients with Parkinson's disease. This was a cross sectional case control study carried out at a tertiary health facility in South-south Nigeria. Participants with PD were consecutively recruited from the neurology outpatient clinics. Demographic and disease-specific data were obtained with the use of a pre-tested questionnaire. Cognitive performance of thirty patients with PD were compared with thirty demographically matched controls using the Community Screening Instrument for Dementia (CSID). CSID was already validated among Nigerians. The frequency of cognitive impairment using the CSID was 50% for PD patients (3.3% for controls). Poor cognitive performance was observed across several cognitive domains including language, executive dysfunction, psychomotor speed, and constructional apraxia among PD patients. The independent predictors of the overall cognitive impairment in patients with PD determined by logistic regression analysis include recall deficiency (p = 0.007), impairment with naming (p = 0.044), apraxia (p = 0.003), Hoen&Yahr staging (p = 0.046), UPDRS score (p = 0.015) and age at presentation (p = 0.014). Cognitive impairments occur more frequently in patients with PD compared to controls. This study also demonstrated the predictive role of severity of disease based on Hoehn &Yahr staging and UPDRS score, and presence of recall deficiency, poor naming ability and apraxia.

Verbal ability in postmenopausal women in relation to age, cognitive and reproductive factors

Word-finding difficulties have been associated with age and, in women, lowered sex hormone levels following menopause. However, there is limited understanding of the ways that specific aspects of word-finding are shaped by women's age, reproductive histories, and background factors such as education. The current study investigated the effects of age, cognitive and reproductive factors on word-finding abilities in 53 healthy postmenopausal women aged 48–79. A questionnaire was used to gather demographic information and reproductive history. A battery of verbal fluency, continuous series, and naming tasks was designed to assess word-finding across different sensory modalities and cognitive demands. Category and letter fluency were quantified as total number of correct words produced on each task. For continuous series, switch rates and switch costs were computed. For the naming tasks, accuracy and latency measures were used. There were three key findings. Firstly, there was a consistent positive association between education and all word-finding measures, i.e., verbal fluency, continuous series, and naming. Secondly, age-related declines were seen on tasks heavily dependent on working memory such as the continuous series task. Thirdly, reproductive factors across the lifespan such as age at menarche and reproductive years showed subtle effects on naming abilities, but not on verbal fluency or continuous series. The results highlight that word-finding abilities in healthy postmenopausal women are shaped by factors associated with their early years (education, age at menarche) and later adult life (age, reproductive years). The study also distinguished between the more global effects of education, and the more task-specific associations with age and reproductive variables, on verbal task performance after menopause.
