Among the various types of dementia, Alzheimer's disease (AD) is the most common in the elderly, characterized by episodic memory impairment and also a decline in executive functions. Mild cognitive impairment (MCI) is considered a transitional stage between normal ageing and dementia, often described as a pre-dementia state. Distinguishing between these states is of paramount importance for the detection and appropriate care of patients. Functional Assessment Battery (FAB) is a screening tool for assessing executive function. In this study, 36 healthy individuals (HC), 31 single-domain amnestic mild cognitive impairment (aMCI) patients, and 29 Alzheimer's disease (AD) patients were assessed using FAB to determine its reliability, validity, and discriminative validity in a Spanish sample. Results indicated a good internal consistency of FAB in the AD sample (α = .71), but not in the aMCI group (α = .49). Significant differences between HC and both aMCI and AD groups were observed in the total scores of FAB. The FAB also showed good accuracy in distinguishing between HC and patients (AUC = 0.85), with an estimated optimal cut-off point of 16.5. However, its ability to distinguish between aMCI and AD individuals was lower (AUC = 0.68).

With the advent of disease-modifying therapies, the optimisation of diagnostic pathways is increasingly urgent, particularly in the early stages of Alzheimer's disease. Yet, biomarker-driven frameworks eclipse neuropsychological testing as an ancillary tool rather than recognising it as a core component of clinical assessment. Emerging evidence indicates that relying solely on biomarkers does not provide a dependable forecast for the onset or progression of dementia. This drawback underscores how important neuropsychology is. Nonetheless, the clinical adoption of neuropsychological tests for diagnostic purposes requires a paradigm shift towards a more rigorous methodology. Despite its recognised diagnostic potential, the current neuropsychological framework is constrained by thresholds derived from normative distributions rather than Clinimetrics. Many existing tests rely on arbitrary cut-offs that do not account for disease prevalence, personological variability, or real-world cognitive performance. This oversimplified approach reduces the sensitivity of neuropsychological assessments and limits their integration into clinical practice. The development of population-specific clinimetric studies that establish weighted cut-offs for sensitivity and specificity based on clinical aims is crucial to ensure clinically meaningful decision-making.","PeriodicalId":197,"journal":{"name":"Journal of Neuropsychology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144833539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identifying determinants of DS is needed to enable prediction and develop psychological interventions. A promising candidate may be self-concept and changes thereof, so-called self-discrepancy. Consulting recent self-concept models, we investigated the role of self-concept subdomains and their individual importance. Within a prospective longitudinal study, 120 stroke survivors were interviewed via telephone 3 years post-ictus to assess present and past self-concept, self-discrepancy, self-concept subdomains and DS. The association of self-concept measures and DS was investigated using an ANCOVA. Controlling for established determinants (age, sex, history of depression, functional independence, social support), multiple regression analyses were used to examine the independent influence of self-concept measures and the role of subdomains and importance-weightings. Self-discrepancy showed a significant interaction with DS (F (1, 118) = 32.69, p < .001, η2 = .22). DS showed a stronger association with present (r = -.72) than with past self-concept (r = -.34) and self-discrepancy (r = -.47; all p < .001). Age, history of depression, social support and present self-concept were independent predictors of DS while functional independence was not (∆F (1, 113) = 48.04, p < .001). Importance-weighting of subdomains did not affect explained variance, though the number of self-concept subdomains showing significant association with DS increased. Findings propose appraisals of self-concept as independent predictors of DS after stroke. Considering individual importance of subdomains reveals their differential influence. The results suggest investigating the use of general self-concept for prediction and considering the individual relevance of subdomains in psychological interventions after stroke.","PeriodicalId":197,"journal":{"name":"Journal of Neuropsychology","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144648093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This complicates the process of a clinically meaningful assessment. To help address this, we provide normative data for three well-validated tests of executive functions, the Stroop Colour/Word Test, the Controlled Oral Word Association Test and the Hayling Sentence Completion Test, alongside scores from an estimate of general intellectual ability. These tests are sensitive to frontal lobe damage and provide clinicians with information about possible focal damage to the left and right frontal lobes. Percentiles are presented for five age cohorts across the adult lifespan (18-92 years). A regression equation with age and predicted full-scale IQ also allows for the categorisation of normal and defective performance on the Stroop and Hayling tests. Given the increasing proportion of older adults requiring neuropsychological assessment, we investigated separately two groups in the older adult range: 65-79 years and 80-92 years. We found a decline in performance for older adults on all three tests. This decline was more marked amongst lower scoring older adults.

However, it is currently unclear what drives these. Here we applied Load Theory of Attention to investigate the role of perceptual load in the relationship between attention, distraction and fatigue levels in PSF. Thirty-two chronic stroke survivors performed a selective attention task of either low, medium or high perceptual load (varied through the number of relevant target features and their combinations). Neural responses to targets and distractor checkerboard flicker (vs. no flicker) were measured with frequency-tagged EEG responses. The results showed that fatigue severity scores were predictive of response slowing, and that this slowing was increased with higher levels of perceptual load. Fatigue severity was also associated with increased neural responsiveness to distractors, specifically: EEG 10 Hz (distractor flickering frequency) power was greater in the presence (vs. absence) of distractor flicker for participants with high (vs. low) fatigue-symptoms scores, across all levels of perceptual load in the later time period of each task trial. Overall, these results clarify the exacerbating effects of perceptual load on fatigue-related slowing, stressing the importance of cognitive, as opposed to purely motoric, deficits. Importantly, they demonstrate that increased fatigue severity involves reduced ability to suppress neural responses to irrelevant distractors, irrespective of perceptual load on attention. An account for attention in PSF based on a specific deficit in distractor suppression that is found irrespective of task demands can explain a myriad of PSF symptoms (e.g. sensory perceptual overload, difficulties to concentrate).","PeriodicalId":197,"journal":{"name":"Journal of Neuropsychology","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144473566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
