Abstract Objective: To provide clarification on the distinction between cognitive screening, cognitive testing, and neuropsychological assessment and highlight practical implications. Method: Non-systematic brief clinical review. Results: There is a present lack of explicit distinction between the various levels of measurement of cognitive functioning with regard to goals, indications for use, levels of complexity, and outcome. There is also a lack of guidance regarding the identification of who should be responsible for the administration and interpretation at each level. Conclusions: There is a growing awareness of the importance of cognitive health and disability, and of the importance of measurement of cognitive functions across the lifespan. For example, cognitive screening has been mandated by the Patient Protection and Affordable Care Act of 2010, and language contained within new psychiatric diagnostic criteria and healthcare regulatory changes reflect increased consideration of the importance of measurement of cognition. Changes such as these necessitate greater clarity on this important issue as it bears implications for professional practice, which ranges from education and training competencies, practice standards, and the way that neuropsychologists clarify and advocate for the value of specialty referrals for comprehensive assessment in a competitive and ever-changing healthcare market.

Abstract Objective: Older adults’ motor sequencing performance is more reliant on executive functioning (EF) and more susceptible to complexity than that of younger adults. This study examined for which aspects of motor sequencing performance these relationships hold. Methods: Fifty-seven younger and 90 non-demented, community-dwelling, older adults completed selected subtests from the Delis–Kaplan Executive Function System as indices of EF and component processes (CP; graphomotor speed; visual scanning; etc.), as well as a computerized motor sequencing task (Push Turn Taptap task; PTT). The PTT requires participants to perform motor sequences that become progressively more complex across the task’s four blocks, and is designed to assess action planning, action learning, and motor control speed and accuracy. Results: Hierarchical regressions using each discrete aspect of performance as the dependent variable revealed that action planning is the only aspect of motor sequencing that is uniquely related to EF (beyond the CP composite) for both age groups. Action learning and motor control accuracy are uniquely associated with EF for older adults only, and only if the sequences are complex. Component processes do not fully account for the unique relationships between motor sequencing and EF in older adults. Conclusions: These results clarify prior findings by showing (a) more aspects of motor sequencing relate to EF for older compared to younger adults and (b) for these unique relationships, EF is only related to action during the generation of sequences that are complex. These findings further our understanding of how aging shapes the links between EF and motor actions, and can be used in evidence-based and theoretically driven intervention programs that promote healthy aging.

Abstract Objective: The aim was to examine the reliability and validity of two measures of learning and memory within the CogState Computerized Battery: the One Card Learning (OCL) and the Continuous Paired Associative Learning (CPAL). Comparison of various reliable change measures was also included to examine rate of correct cognitive change classification, in particular, when using the Within-Subject Standard Deviation (WSD). Method: The OCL and the CPAL tests were administered twice and compared to standard and experimental versions of conventional neuropsychological tests in patients with seizure disorders (Baseline n = 80, Follow-up = 54) and university students (Baseline n = 89, Follow-up n = 87). Calculations of Reliable Change Indices (RCIs) on individual performance were obtained to detect reliable change across time using published CogState and current study parameters. Results: Results showed low retest reliabilities in both OCL and CPAL tests (r’s = .49–.77). Small to medium convergent validity correlations with traditional tests of learning and working memory were also found. Discrepancies in RCIs methods on performance estimation were observed when different test parameters and reliabilities were used. In contrast to recent recommendations by publishers of the CogState tests, the WSD method was found to substantially increase the rate of Type-I error when tests reliabilities were low. Conclusions: Unsatisfactory reliability and validity estimates suggest caution regarding the CogState computerized measures of learning and memory as opposed to conventional tests. Caution should be used when interpreting OCL and CPAL test scores, as confidence intervals may be wide and encompass much of the population range. In line with previous recommendations, use of the WSD to detect change in performance over time should be avoided in neuropsychological testing, as this change measure is prone to elevated misclassification rates compared to other methods. Further independent research is needed to improve the psychometrics of CogState OCL and CPAL measures.

Abstract Objective: Creutzfeldt–Jakob disease (CJD) is a rare, rapidly progressive, and fatal neurodegenerative disease with neuropsychological sequelae. This study highlighted a rare presentation of CJD (e.g. corticobasal syndrome [CBS]), reviewed updated diagnostic criteria and procedures for CJD (e.g. diffusion weighted imaging [DWI], real-time quaking-induced conversion [RT-QuIC]), and discussed differential diagnoses. Method: Case report methodology focused on a 68-year-old, Hispanic, right-handed man with 11 years of education. He presented with a 1–2-month history of gait and motor difficulties (e.g. rigidity, myoclonus). Results: After evaluation, a ‘cortical ribboning’ pattern on DWI and positive RT-QuIC was integrated with performance on neurobehavioral exam (i.e. alien limb phenomenon, unilateral ideomotor apraxia) and neuropsychological testing (i.e. frontal-parietal dysfunction pattern) to reach a diagnosis of sCJD-CBS. The patient expired 3 months after onset of symptoms. Conclusions: This literature review and case report highlighted the importance of staying abreast of developments in neurological literature and the added value of neuropsychology, when integrated with newer procedures, for confirming and excluding diagnostic considerations.

Abstract Objective: Studies have reported that the presence of a third party observer (TPO) during neuropsychological assessments negatively affects the test performance of the examinee. The present study aimed to investigate the effects of a TPO and trait anxiety on neuropsychological performance according to Attentional Control Theory (ACT). Method: A sample of college students was recruited (n = 318) and then 80 participants were selected to represent the high and low trait anxiety groups. Participants of each of group were randomly assigned to either the NTPO (non-TPO) or TPO conditions. The State-Trait Anxiety Inventory – Trait measure (STAI-T), Wisconsin Card Sorting Test (WCST-64), Stroop test, and Rating Scale for Mental Effort (RSME) were administered to both groups. To analyze the data, univariate ANOVAs were conducted. Results: The results indicated that under the conditions without a TPO the group with high trait anxiety had poorer processing efficiency, but under the conditions with a TPO they had poorer processing efficiency and poorer performance effectiveness than the group with low trait anxiety. In addition, the group with low trait anxiety showed poorer processing efficiency in the TPO compared to non-TPO condition. Conclusions: These findings provide support for the hypotheses of ACT regarding the relation between observer presence and poorer performance on neuropsychological tests, with individuals with higher trait anxiety showing greater negative effects. Implications and suggestions for further research are discussed.

Abstract Objective: Evaluating assessment validity is expected in neuropsychological evaluation, particularly in cases with identified secondary gain, where malingering or somatization may be present. Assessed with standalone measures and embedded indices, all within the testing portion of the examination, research on validity of self-report in the clinical interview is limited. Based on experience with litigation-involved examinees recovering from mild traumatic brain injury (mTBI), it was hypothesized that inconsistently reported date of injury (DOI) and/or loss of consciousness (LOC) might predict invalid performance on neurocognitive testing. Method: This archival study examined cases of litigation-involved mTBI patients seen at an outpatient neuropsychological practice in Philadelphia, PA. Coded data included demographic variables, performance validity measures, and consistency between self-report and medicolegal records. Results: A significant relationship was found between the consistency of examinees’ self-report with records and their scores on performance validity testing, X2 (1, N = 84) = 24.18, p < .01, Φ = .49. Post hoc testing revealed significant between-group differences in three of four comparisons, with medium to large effect sizes. A final post hoc analysis found significance between the number of performance validity tests (PVTs) failed and the extent to which an examinee incorrectly reported DOI r(83) = .49, p < .01. Using inconsistently reported LOC and/or DOI to predict an examinee’s performance as invalid had a 75% sensitivity and a 75% specificity. Conclusion: Examinees whose reported DOI or LOC differs from records may be more likely to fail one or more PVTs, suggesting possible symptom exaggeration and/or under performance on cognitive testing.s
摘要目的:评估评估效度在神经心理学评估中是预期的，特别是在确定继发性增益的情况下，其中可能存在装病或躯体化。由于采用独立测量方法和嵌入指标进行评估，且均在考试的测试部分，因此对临床访谈中自我报告效度的研究有限。根据参与诉讼的考生从轻度创伤性脑损伤(mTBI)恢复的经验，我们假设不一致的报告损伤日期(DOI)和/或意识丧失(LOC)可能预测神经认知测试的无效表现。方法:本档案研究调查了在宾夕法尼亚州费城一家门诊神经心理学诊所就诊的涉及诉讼的mTBI患者。编码数据包括人口统计变量、效能效度测量以及自我报告与医学法律记录之间的一致性。结果:考生自述与记录的一致性与成绩效度测验成绩有显著相关，X2 (1, N = 84) = 24.18, p < 0.01， Φ = 0.49。事后检验显示，4个比较中有3个组间差异显著，效应量中等到较大。最后的事后分析发现，绩效效度测试(pvt)失败的次数与考生错误报告DOI的程度之间存在显著性r(83) = .49, p < .01。使用不一致的LOC和/或DOI来预测考生无效的表现具有75%的敏感性和75%的特异性。结论:报告的DOI或LOC与记录不同的考生更有可能不通过一项或多项pvt，这可能表明症状夸大和/或认知测试表现不佳

Abstract Objective: The Brain Injury Cognitive Screen (BICS) was developed as an in-service cognitive assessment battery for acquired brain injury patients entering community rehabilitation. The BICS focuses on domains that are particularly compromised following TBI, and provides a broader and more detailed assessment of executive function, attention and information processing than comparable screening assessments. The BICS also includes brief assessments of perception, naming, and construction, which were predicted to be more sensitive to impairments following non-traumatic brain injury. The studies reported here examine preliminary evidence for its validity in post-acute rehabilitation. Method: In Study 1, TBI patients completed the BICS and were compared with matched controls. Patients with focal lesions and matched controls were compared in Study 2. Study 3 examined demographic effects in a sample of normative data. Results: TBI and focal lesion patients obtained significantly lower composite memory, executive function and attention and information processing BICS scores than healthy controls. Injury severity effects were also obtained. Logistic regression analyses indicated that each group of BICS memory, executive function and attention measures reliably differentiated TBI and focal lesion participants from controls. Design Recall, Prospective Memory, Verbal Fluency, and Visual Search test scores showed significant independent regression effects. Other subtest measures showed evidence of sensitivity to brain injury. Conclusions: The study provides preliminary evidence of the BICS’ sensitivity to cognitive impairment caused by acquired brain injury, and its potential clinical utility as a cognitive screen. Further validation based on a revised version of the BICS and more normative data are required.

Further validation based on a revised version of the BICS and more normative data are required.","PeriodicalId":197334,"journal":{"name":"The Clinical neuropsychologist","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123561917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Objective: A 71-year-old (MN) with an 11-year history of left onset tremor diagnosed as Parkinson’s disease (PD) completed longitudinal brain magnetic resonance imaging (MRI) and neuropsychological testing. MRI scans showed an asymmetric caudate nucleus (right < left volume). We describe this asymmetry at baseline and the progression over time relative to other subcortical gray, frontal white matter, and cortical gray matter regions of interest. Isolated structural changes are compared to MN’s cognitive profiles. Method: MN completed yearly MRIs and neuropsychological assessments. For comparison, left onset PD (n = 15) and non-PD (n = 43) peers completed the same baseline protocol. All MRI scans were processed with FreeSurfer and the FMRIB Software Library to analyze gray matter structures and frontal fractional anisotropy (FA) metrics. Processing speed, working memory, language, verbal memory, abstract reasoning, visuospatial, and motor functions were examined using reliable change methods. Results: At baseline, MN had striatal volume and frontal lobe thickness asymmetry relative to peers with mild prefrontal white matter FA asymmetry. Over time only MN’s right caudate nucleus showed accelerated atrophy. Cognitively, MN had slowed psychomotor speed and visuospatial-linked deficits with mild visuospatial working memory declines longitudinally. Conclusions: This is a unique report using normative neuroimaging and neuropsychology to describe an individual diagnosed with PD who had striking striatal asymmetry followed secondarily by cortical thickness asymmetry and possible frontal white matter asymmetry. His decline and variability in visual working memory could be linked to ongoing atrophy of his right caudate nucleus.

Abstract Objective: Early detection of children with developmental delay is crucial for determining which children require close surveillance and intervention services. For many decades, the Bayley Scales has been the most widely used objective measure of early developmental delay, both in clinical and research settings. Significant structural changes were incorporated in the most recent edition, the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III). This article reviews the psychometric properties of the Bayley-III and investigates criticisms raised on the Bayley-III, namely that it overestimates developmental status and is a poor predictor of later functioning. Method: This critical review examines the literature on the Bayley-III, which was released in 2006. Results: The Cognitive, Language, and Motor composites of the Bayley-III overestimate development, resulting in an under-identification of children with developmental delay. A range of strategies have been proposed for dealing with the inflated scores on the Bayley-III, none of which are ideal. Evidence to date suggests that the Bayley-III is a poor predictor of later cognitive and motor impairments. Conclusions: The Bayley-III needs new norms, or alternatively, it may be time for a new edition of the Bayley Scales.
