  • Effects of Delay Duration on the WMS Logical Memory Performance of Older
           Adults with Probable Alzheimer's Disease, Probable Vascular Dementia, and
           Normal Cognition
    • Authors: Montgomery V; Harris K, Stabler A, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>To examine how the duration of time delay between Wechsler Memory Scale (WMS) Logical Memory I and Logical Memory II (LM) affected participants’ recall performance.<div class="boxTitle">Method</div>There are 46,146 total Logical Memory administrations to participants diagnosed with either Alzheimer's disease (AD), vascular dementia (VaD), or normal cognition in the National Alzheimer's Disease Coordinating Center's Uniform Data Set.<div class="boxTitle">Results</div>Only 50% of the sample was administered the standard 20–35 min of delay as specified by WMS-R and WMS-III. We found a significant effect of delay time duration on proportion of information retained for the VaD group compared to its control group, which remained after adding LMI raw score as a covariate. There was poorer retention of information with longer delay for this group. This association was not as strong for the AD and cognitively normal groups. A 24.5-min delay was most optimal for differentiating AD from VaD participants (47.7% classification accuracy), an 18.5-min delay was most optimal for differentiating AD versus normal participants (51.7% classification accuracy), and a 22.5-min delay was most optimal for differentiating VaD versus normal participants (52.9% classification accuracy).<div class="boxTitle">Conclusions</div>Considering diagnostic implications, our findings suggest that test administration should incorporate precise tracking of delay periods. We recommend a 20-min delay with 18–25-min range. Poor classification accuracy based on LM data alone is a reminder that story memory performance is only one piece of data that contributes to complex clinical decisions. However, strict adherence to the recommended range yields optimal data for diagnostic decisions.</span>

  • Medical Symptom Validity Test Performance Following Moderate-Severe
           Traumatic Brain Injury: Expectations Based on Orientation Log
    • Authors: Macciocchi SN; Seel RT, Yi A, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>This study examined performance on the Medical Symptom Validity test (MSVT) during acute rehabilitation for moderate-severe traumatic brain injury (TBI) stratified by Orientation Log (O-Log) scores.<div class="boxTitle">Method</div>Participants were 77 prospectively enrolled persons who sustained moderate-severe TBI and were acutely hospitalized secondary to the cognitive, medical and physical sequelae of their TBI. Participants were administered neuropsychological metrics, the O-Log and the MSVT a mean of 44 days post injury.<div class="boxTitle">Results</div>Significantly lower neurocognitive test scores were observed among participants who remained in post-traumatic amnesia (O-Log scores ranging from 20 to 24) versus those who were oriented (O-Log scores ranging from 25 to 30). MSVT performance was lower among participants who remained in post-traumatic amnesia. When participants O-Log scores were unimpaired (30), performance on the MSVT was also unimpaired on immediate recognition (IR) and delayed recognition (DR). A small percentage of participants performed below MSVT interpretive expectations on CNS. As O-Log scores decreased, MSVT performance also declined on some, but not all MSVT metrics. The sample as a whole performed at or above expectations on MSVT criterion B2 (IR) = 96.6%; (DR) = 94.8%; consistency (CNS) = 92.9%; paired associate (PA) = 86.4% and delayed free recall (FR) = 46.8%.<div class="boxTitle">Conclusions</div>MSVT performance stratified by O-Log scores provides basal expectation levels for persons with acute, moderate-severe impairment in cognitive skills secondary to TBI. Our data demonstrate that persons with significant neurocognitive impairment who are oriented generally perform at or above MSVT interpretive guidelines.</span>

  • Emotional Intelligence in Agenesis of the Corpus Callosum
    • Authors: Anderson LB; Paul LK, Brown WS.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>People with agenesis of the corpus callosum (AgCC) with normal general intelligence have deficits in complex cognitive processing, as well as in social cognition. It is uncertain the extent to which impoverished processing of emotions may contribute to social processing deficiencies. We used the Mayer–Salovey–Caruso Emotional Intelligence Test to clarify the nature of emotional intelligence in 16 adults with AgCC. As hypothesized, persons with AgCC exhibited greater disparities from norms on tests involving more socially complex aspects of emotions. The AgCC group did not differ from norms on the Experiential subscale, but they were significantly below norms on the Strategic subscale. These findings suggest that the corpus callosum is not essential for experiencing and thinking about basic emotions in a “normal” way, but is necessary for more complex processes involving emotions in the context of social interactions.</span>

  • Effects of Sleep Loss on Subjective Complaints and Objective
           Neurocognitive Performance as Measured by the Immediate Post-Concussion
           Assessment and Cognitive Testing
    • Authors: Stocker RJ; Khan H, Henry L, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>This study examined the effects of total and partial sleep deprivation on subjective symptoms and objective neurocognitive performance, as measured by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) in a sample of healthy adults.<div class="boxTitle">Method</div>One-hundred and two, right-handed, healthy participants (between ages 18 and 30 years old) completed three consecutive nights in the sleep laboratory with concurrent continuous polysomnography monitoring. Night 1 served as a baseline night. Prior to Night 2, they were randomly assigned to one of three sleep conditions: undisrupted normal sleep (<span style="font-style:italic;">N</span> = 34), sleep restriction (50% of habitual sleep, <span style="font-style:italic;">N</span> = 37), or total sleep deprivation (<span style="font-style:italic;">N</span> = 31). Participants slept undisturbed on Night 3. ImPACT was administered on three separate occasions.<div class="boxTitle">Results</div>Sleep loss was associated with increased severity of subjectively reported affective, cognitive, physical, and sleep symptoms. Although objective neurocognitive task scores derived from the ImPACT battery did not corroborate subjective complaints, sleep loss was associated with significant differences on tasks of visual memory, reaction time, and visual motor speed over time.<div class="boxTitle">Conclusions</div>While self-report measures suggested marked impairments following sleep loss, deficits in neurocognitive performance were observed only on three domains measured with ImPACT. ImPACT may capture subtle changes in neurocognitive performance following sleep loss; however, independent and larger validation studies are needed to determine its sensitivity to acute sleep loss and recovery sleep. Neurocognitive screening batteries may be useful for detecting the effects of more severe or chronic sleep loss under high-stress conditions that mimic high-risk occupations.</span>

  • Neuropsychology and Rehabilitation Services in the United States: Brief
           Report from a Survey of Clinical Neuropsychologists
    • Authors: Block C; Santos OA, Flores-Medina Y, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>To provide a brief presentation of preliminary data on rehabilitation services provided by clinical neuropsychologists within the United States.<div class="boxTitle">Method</div>This survey utilized data extracted from a larger international research study conducted in 39 countries including <span style="font-style:italic;">N</span> = 173 professionals who reported to engage in neuropsychological rehabilitative services within the past year (63.6% female, 44.36 ± 11.83 years of age) took part in the study.<div class="boxTitle">Results</div>Neuropsychologists providing rehabilitation services in the United States in the past year were more likely to provide individual versus group therapy, likely to employ technology (e.g., personal computers, mobile phones/smartphones) as part of treatment services, see a range of diagnostic groups most prominently traumatic brain injury and stroke/vascular conditions, and work to address a range of both cognitive (e.g., memory, attention/concentration, and executive functioning) and psychological (e.g., emotional/behavioral adjustment and well-being, awareness of disability/disease) issues.<div class="boxTitle">Conclusions</div>Prior published surveys suggest that clinical neuropsychologists have a growing involvement in rehabilitation services within the United States but with little clarity as to the actual characteristics of actual professional activities and practices. The present study aimed to provide such information and hopefully will be helpful in promoting additional systematic studies in this area.</span>

  • A Comparative Study of Tower of London Scoring Systems and Normative Data
    • Authors: Michalec J; Bezdicek O, Nikolai T, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>Tower of London (ToL) is a planning ability task that includes multiple versions. The original ToL was developed by Shallice together with two scoring systems (ToL-SS). Another two ToL-SS were proposed by Anderson et al. and Krikorian et al. The purpose of this study is to provide normative data for four ToL-SS and explore the effects of demographic variables on ToL performance. Furthermore, we aimed to determine the discriminative validity of these ToL-SS in clinical samples.<div class="boxTitle">Method</div>Four groups were included in the study: a normative sample of healthy adults (HC; <span style="font-style:italic;">n</span> = 298); patients with Parkinson's disease with mild cognitive impairment (PD-MCI; <span style="font-style:italic;">n</span> = 52) and without cognitive impairment (PD-ND; <span style="font-style:italic;">n</span> = 57); and patients with schizophrenia (SCH; <span style="font-style:italic;">n</span> = 28). The effects of demographic variables on ToL-SS were examined in the HC group. Between-groups comparisons of ToL-SS were conducted using regression analysis with dummy codes.<div class="boxTitle">Results</div>All four ToL-SS were not significantly affected by age, whereas the effect of gender and education is not consistent. ToL-SS significantly (<span style="font-style:italic;">p</span> < .05) differentiate HC from PD-MCI and SCH. Cohen's effect size coefficients <span style="font-style:italic;">d</span> range from 0.68 to 1.29. Internal consistency coefficients (Cronbach's <span style="font-style:italic;">α</span>) of ToL-SS range from 0.33 to 0.60.<div class="boxTitle">Conclusions</div>Despite poor to questionable internal consistency of ToL-SS, the discriminative validity and clinical utility for assessing planning deficits in PD-MCI and SCH are high. This study provides normative standards for all four ToL-SS on an adult population for use in clinical practice.</span>

  • Comparison of Neuropsychological Patterns in Nigerians with different
           Heart Failure Phenotypes
    • Authors: Adebayo PB; Akintunde AA, Adebayo AJ, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>The aim of this study was to determine the influence of left ventricular dysfunction type on the pattern of neuropsychological dysfunctions among heart failure (HF) subjects.<div class="boxTitle">Method</div>A sub-analysis of the data of subjects recruited in a cross-sectional survey of cognitive dysfunction among Nigerians with HF was performed. Cognitive performance on the Community Screening Interview for Dementia (CSI'D), Word List Learning Delayed Recall (WLLDR), Boston Naming Test (BNT), and Modified Token Test (MTT) were compared between heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). Clinical and echocardiographic correlation analysis with cognitive performance was performed.<div class="boxTitle">Results</div>Subjects with HFpEF were impaired on the WLLDR (71.4% vs. 34.6%, <span style="font-style:italic;">p</span> = .026). The group with HFpEF scored lower on the language domain (definition subscale) of CSI'D (<span style="font-style:italic;">p</span> = .036), and WLLDR (<span style="font-style:italic;">p</span> = .005). The performance on the MTT (<span style="font-style:italic;">p</span> = .185) and BNT (<span style="font-style:italic;">p</span> = .923) were comparable between the two groups. An inverse relationship was found between pulse pressure and delay recall (<span style="font-style:italic;">r</span> = −.565 <span style="font-style:italic;">p</span> = .003) among the cohort with HFpEF whereas body mass index, BMI (<span style="font-style:italic;">r</span> = −.737, <span style="font-style:italic;">p</span> = .023) and tricuspid valve E/A ratio, TVEA (<span style="font-style:italic;">r</span> = −.650, <span style="font-style:italic;">p</span> = .042) showed an inverse relationship with the total CSI'D score in the cohort with HFrEF.<div class="boxTitle">Conclusions</div>Cognitive dysfunction is largely similar between the two groups. Delay recall is however poorer among subjects with HFpEF. Regular cognitive screening is advocated among HF subjects to prevent non-adherence with therapeutic options.</span>

  • Assessment of Self-Awareness of Cognitive Function: Correlations of
           Self-Ratings with Actual Performance Ranks for Tests of Processing Speed,
           Memory and Executive Function in Non-Clinical Samples
    • Authors: Rothlind J; Dukarm P, Kraybill M.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>For individuals with neurologic disorders, self-awareness of cognitive impairment is associated with improved treatment course and clinical outcome. However, methods for assessment of levels of self-awareness are limited, and most require collateral information, which may not be readily available. Although distortions in self-awareness are most often associated with low cognitive ability, the frequently mixed pattern of cognitive strengths and deficits in individuals with neurologic disorders complicates assessment. The present study explores relationships between actual test performance and self-ratings, utilizing a brief probe administered during testing. The “common-metric” approach solicits self-appraisal ratings in percentile equivalents and capitalizes on available normative data for specific standardized neuropsychological tests to allow direct comparisons.<div class="boxTitle">Method</div>A convenience sample of 199 adults recruited from community sources participated in this study, including healthy adults and neuropsychologically “at-risk” volunteers who were HIV positive and/or endorsing heavy current alcohol consumption. Immediately following completion of standardized neuropsychological tests, participants estimated their own percentile ranking.<div class="boxTitle">Results</div>Across study groups, participant's estimates of their own percentile rank were modestly correlated with actual performance ranking. Highest correlations were obtained for tests of learning, memory and conceptual reasoning, and executive function, with smaller correlations for simple tests of motor and psychomotor speed.<div class="boxTitle">Conclusions</div>The study reveals normal biases affecting the self-appraisal during standardized testing, and suggests that a common-metric approach for assessing self-appraisal may play a role in establishing clinical thresholds and identifying and quantifying reductions in insight in persons with neuropsychological deficits</span>

  • Word Memory Test Performance Across Cognitive Domains, Psychiatric
           Presentations, and Mild Traumatic Brain Injury
    • Authors: Rowland JA; Miskey HM, Brearly TW, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>The current study addressed two aims: (i) determine how Word Memory Test (WMT) performance relates to test performance across numerous cognitive domains and (ii) evaluate how current psychiatric disorders or mild traumatic brain injury (mTBI) history affects performance on the WMT after excluding participants with poor symptom validity.<div class="boxTitle">Method</div>Participants were 235 Iraq and Afghanistan-era veterans (<span style="font-style:italic;">M</span><sub>age</sub> = 35.5) who completed a comprehensive neuropsychological battery. Participants were divided into two groups based on WMT performance (Pass = 193, Fail = 42). Tests were grouped into cognitive domains and an average <span style="font-style:italic;">z</span>-score was calculated for each domain.<div class="boxTitle">Results</div>Significant differences were found between those who passed and those who failed the WMT on the memory, attention, executive function, and motor output domain <span style="font-style:italic;">z</span>-scores. WMT failure was associated with a larger performance decrement in the memory domain than the sensation or visuospatial-construction domains. Participants with a current psychiatric diagnosis or mTBI history were significantly more likely to fail the WMT, even after removing participants with poor symptom validity.<div class="boxTitle">Conclusions</div>Results suggest that the WMT is most appropriate for assessing validity in the domains of attention, executive function, motor output and memory, with little relationship to performance in domains of sensation or visuospatial-construction. Comprehensive cognitive batteries would benefit from inclusion of additional performance validity tests in these domains. Additionally, symptom validity did not explain higher rates of WMT failure in individuals with a current psychiatric diagnosis or mTBI history. Further research is needed to better understand how these conditions may affect WMT performance.</span>

  • Sandbagging on the Immediate Post-Concussion Assessment and Cognitive
           Testing (ImPACT) in a high school athlete population
    • Authors: Higgins KL; Denney RL, Maerlender A.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div>The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called “sandbagging,” in order to return to their baseline cognitive scores, and thus to play, more quickly. This research examines ImPACT baseline scores when high school athletes were asked to attempt to “sandbag,” and compares those scores with scores obtained when they were asked to give their “best effort.” Fifty-four high school student athlete volunteers participated in the study. In contrast to previous research that just looked at the cut-score invalidity indicators built into ImPACT, this research developed a regression equation to predict sandbagging. A logistic regression equation developed with four variables that demonstrated the largest effect size between “best effort” and “sandbagged” baselines showed a 99.7% classification accuracy for the “best effort” and “sandbag” groups.</span>

  • Using Multivariate Base Rates to Interpret Low Scores on an Abbreviated
           Battery of the Delis–Kaplan Executive Function System
    • Authors: Karr JE; Garcia-Barrera MA, Holdnack JA, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>Executive function consists of multiple cognitive processes that operate as an interactive system to produce volitional goal-oriented behavior, governed in large part by frontal microstructural and physiological networks. Identification of deficits in executive function in those with neurological or psychiatric conditions can be difficult because the normal variation in executive function test scores, in healthy adults when multiple tests are used, is largely unknown. This study addresses that gap in the literature by examining the prevalence of low scores on a brief battery of executive function tests.<div class="boxTitle">Method</div>The sample consisted of 1,050 healthy individuals (ages 16–89) from the standardization sample for the Delis–Kaplan Executive Function System (D-KEFS). Seven individual test scores from the Trail Making Test, Color-Word Interference Test, and Verbal Fluency Test were analyzed.<div class="boxTitle">Results</div>Low test scores, as defined by commonly used clinical cut-offs (i.e., ≤25th, 16th, 9th, 5th, and 2nd percentiles), occurred commonly among the adult portion of the D-KEFS normative sample (e.g., 62.8% of the sample had one or more scores ≤16th percentile, 36.1% had one or more scores ≤5th percentile), and the prevalence of low scores increased with lower intelligence and fewer years of education.<div class="boxTitle">Conclusions</div>The multivariate base rates (BR) in this article allow clinicians to understand the normal frequency of low scores in the general population. By use of these BRs, clinicians and researchers can improve the accuracy with which they identify executive dysfunction in clinical groups, such as those with traumatic brain injury or neurodegenerative diseases.</span>

  • The Chinese Version of the Brief Assessment of Cognition in Schizophrenia:
           Data of a Large-Scale Mandarin-Speaking Population
    • Authors: Wang L; Huang Y, Hung C, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle"> </div><div class="boxTitle">Objective</div>The Brief Assessment of Cognition in Schizophrenia (BACS) is a cognitive assessment tool used to measure the broad aspects of cognition that are most frequently impaired in patients with schizophrenia. This study aims to develop the normative data of the Chinese version of the BACS among the Mandarin-speaking population.<div class="boxTitle">Method</div>This cross-sectional study included 382 healthy participants (age range: 19–79 years; mean age: 48.0 ± 16.7 years, 47.6% men) in Taiwan, who were evaluated with the BACS. Means and standard deviations of subtests and composite scores were arranged by age group and gender. The Z-scores calculated based on the U.S. norms were compared to our scores based on the norms established in this study.<div class="boxTitle">Results</div>The raw scores of all the BACS tests (verbal memory, digit sequencing, token motor test, verbal fluency, symbol coding, and Tower of London) were negatively correlated with participants’ age. Women were superior to men in verbal memory, but inferior to them in executive function. Furthermore, applying the U.S. norms of the BACS to determine the performance of the Chinese BACS results in bias with regard to verbal memory, token motor test, verbal fluency, symbol coding, Tower of London and composite score.<div class="boxTitle">Conclusions</div>These findings demonstrate that directly applying western cognitive norms to a Mandarin-speaking population can cause biased interpretations. The results of this study can be an important reference for clinical settings and research related to cognitive assessments in Mandarin-speaking Chinese populations.</span>
