Front Psychiatry 2022; 13:788825. [PMID: 35479487 PMCID: PMC9035546 DOI: 10.3389/fpsyt.2022.788825] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Accepted: 02/25/2022] [Indexed: 11/30/2022] Open
Abstract
This study aimed to suggest an attention assessment tool using a Digital Pen for measuring the temporal-spatial parameters during the Number Cancelation Test (NCT), and then to establish the normative data for the NCT among children in kindergartens and primary schools in China by recruiting a total of 989 children (496 males). Four measures, i.e., selective attention (SA), speed of cognitive processing (SpC), averaged time of circlings (ATC), and averaged circumference of circled curves (ACCC), were proposed to evaluate the NCT performance. They basically have a development trend with fast speed in the beginning before Grade 1 or 2 of primary schools, and then enter an extremely slow development period (with ceiling or floor effect). SA and SpC have gender and grade main effects, while ATC and ACCC have the grade main effect, only. In particular, females have higher SA scores than males in middle class of kindergarten, and Grade 2-Grade 5 of primary school, but no gender differences in other grades; females have higher SpC scores than males in middle class of kindergarten, and Grade 3-4 of primary school, but no gender differences in other grades. More importantly, in clinical practice, if SA or SpC measure of a child is below than the 5th centile (i.e., p5 level) of his/her grade-specific normative data, then this child may be predicted to have a high-risk of learning disabilities. Findings suggest that the proposed method can be used for early screening of learning disabilities by setting appropriate cut-off values.

Abstract
Objective Cognitive decline is a key characteristic of Huntington’s disease (HD). This study aimed to investigate the diagnostic accuracy of a cognitive battery with six tests used by most HD research centers to assess cognitive impairment in HD. Method In total, 106 HD patients in different disease stages with more (HD-CD, N = 30) and less cognitive impairments (HD-NC, N = 70) and 100 healthy controls (NC) were matched by age, sex, and education and were examined using a standardized protocol including cognitive, motor, and functional assessments. Results One-way between-groups analysis of variance showed that controls performed significantly better than HD patients and that HD-NC significantly outperformed HD-CD patients in all cognitive tests (NC > HD-NC > HD-CD), with all Games-Howell post-hoc tests p < .001. Analyses using area under the receiver-operating characteristic curve (AUC) disclosed the diagnostic accuracy of all tests included in the battery to discriminate between NC and HD patients with AUC ranging from 0.809 to 0.862 (all p < .001) and between HD-CD and HD-NC patients with AUC ranging from 0.833 to 0.899 (all p < .001). In both analysis, Stroop Color Naming Test showed the highest discriminative potential. Additional analyses showed that cognitive deficits in all domains progressed with disease duration. Moreover, cognitive performance correlated with the severity of motor and functional impairment (all p < .001) and with the Disease Burden Score regardless of disease duration and age. Conclusion Our results indicate that the cognitive battery is a suitable tool for assessing cognitive impairment in HD.

Perseverative Behavior on Verbal Fluency Task in Patients with Huntington's Disease: a Retrospective Study on a Large Patient Sample. Arch Clin Neuropsychol 2020; 35:358-364.

Abstract
OBJECTIVE Patients with Huntington's disease (HD) may show impairments of frontal cortical-subcortical circuits with difficulties on cognitive flexibility tasks. One marker of poor flexibility is "perseveration" behavior, which refers to inappropriate and involuntary production of iterative responses not adequate to the current task demands. This study explored frequency, type, and possible cognitive mechanisms of verbal perseverations in a large sample of HD patients. METHOD A sample of 128 patients with HD underwent phonological and category verbal fluency tests to assess perseverative errors, within a wide neuropsychological, psychopathological, motor, and functional assessment. RESULTS Perseverative errors in verbal fluency task occurred in 89 (69.5%) patients. Patients showing perseverations scored significantly lower than patients without perseverations on tasks tapping executive and motor functions and on functional independence scales. Logistic regression analysis revealed a significant independent association of verbal perseverations with scores on Trail Making Test only. Conclusions: Verbal perseverations are frequent in HD patients and are likely related with impairments of attentional switching and working memory, hampering tracking of verbal responses already produced. Perseverative behavior may serve as a useful clinical marker of cognitive and functional impairment in patients with HD.

Abstract
OBJECTIVE To investigate cognitive flexibility in premanifest and manifest Huntington's disease (HD). BACKGROUND HD is an autosomal dominant neurodegenerative disease characterized by motor, cognitive, and behavioral abnormalities with typical motor symptoms. In this study, we wanted to assess decision making in premanifest (pre-HD) and manifest HD patients. METHODS A total of 77 non-demented subjects including 29 pre-HD, 22 manifest HD patients, and 26 healthy controls (HC) were included. We stratified the pre-HD group based on their estimated years to disease onset into a far (FAR, n = 13) and a near (NEAR, n = 16) group. Furthermore, participants performed the Montreal cognitive assessment battery (MoCA), the trail making task part A and B (TMT A, TMT B), the Symbol digit modalities test (SDMT), and the beads task. RESULTS In the beads task, HD patients gathered less information than all other groups (all p-values < .001). Furthermore, the NEAR group gathered less information than the FAR group (p < .001) and HC (p = .001). There was no difference between the HC and the FAR group (p = 1.0). In the TMT and the SDMT, HD patients were slower than all other groups (all p-values < .01) but there were no other significant differences. CONCLUSIONS Decision making with a higher degree of uncertainty may be an early neuropsychological sign to indicate the disease process prior to reaching criteria for motor diagnosis of HD.

Abstract
Objective In visuo-constructional tasks, patients may reproduce drawings near-to or superimposed on a model, showing the so-called "Closing-in" (CI), often ascribed to a defect in inhibitory control. CI has been described in neurological conditions, but no studies have explored CI in Huntington's disease (HD), a neurodegenerative disorder often involving the frontal cortical-subcortical circuits. We searched for the occurrence of CI in HD patients and systematically investigated its correlates to find a clinical marker of the frontal/executive dysfunctions in the early examination of HD patients. Method We assessed 130 HD participants, who performed a graphic coping task and a neuropsychological, psychiatric, motor, and functional assessment. Results CI occurred in 52/130 (40%) HD patients, with 43/52 (82.7%) superimposing their copy directly on the model. MANOVA showed that HD patients with CI scored significantly poorer on Symbol digit modality test, Stroop-color word - reading test, Stroop-color word - interference test, Trail making test - part B, and Phonological verbal fluency test. However, a logistic regression analysis revealed that the significant predictor of the occurrence of CI was the score on Stroop-color word - interference test. Conclusions HD patients may show CI in graphic tasks, and it could be related to a defect in inhibitory control impeding the switch of attention from the model to the copying space, and releasing a default tendency which causes an attraction of hand movement towards the focus of visual attention. CI might be a useful clinical marker for the early detection of frontal/executive defects in HD patients.

Abstract
Test-retest reliability is an important psychometric property relevant to assessment instruments typically used in neuropsychological assessment. This review presents a quantitative summary of test-retest reliability coefficients for a variety of widely used neuropsychological measures. In general, the meta-analytic test-retest reliabilities of the test scores ranged from adequate to high (i.e., r=.7 and higher). Furthermore, the reliability values were largely robust across factors such as age, clinical diagnosis, and the use of alternate forms. The values for some of the memory and executive functioning scores were lower (i.e., less than r=.7). Some of the possible reasons for these lower values include ceiling effects, practice effects, and across time variability in cognitive abilities measured by those tests. In general, neuropsychologists who use these measures in their assessments can be encouraged by the magnitude of the majority of the meta-analytic test-retest correlations obtained.

Abstract
PURPOSE Evidence for chemotherapy-induced cognitive impairment remains inconclusive. This study was designed to determine the trajectory of cognitive function over time in women with breast cancer, who received doxorubicin and cyclophosphamide (AC) alone or followed by a taxane. Associations between changes in cognitive function and potential covariates including anxiety, depression, fatigue, hemoglobin level, menopausal status, and perception of cognitive function were evaluated. METHODS The Repeatable Battery for the Assessment of Neuropsychological Status, Stroop Test, and Grooved Pegboard were used to assess cognitive function in a group of 71 women prior to chemotherapy, a week after completing the last cycle of AC, as well as 1 week and 6 months after the completion of all chemotherapy. RESULTS Cognitive impairment was found in 23% of women prior to chemotherapy. Hierarchical linear modeling showed significant decreases after receiving chemotherapy followed by improvements 6 months after the completion of chemotherapy in the cognitive domains of visuospatial skill (p < 0.001), attention (p = 0.022), delayed memory (p = 0.006), and motor function (p = 0.043). In contrast, immediate memory, language, and executive function scores did not change over time. CONCLUSION These results suggest that having a breast cancer diagnosis may be associated with cognitive impairment. While chemotherapy may have a negative impact on cognitive function, chemotherapy-related impairments appear to be more acute than chronic side effects of therapy. Further studies are needed to provide insight into the clinical significance and potential mechanisms of cancer and treatment-related cognitive impairments.

Abstract
PRIMARY OBJECTIVE To investigate the test-re-test reliability of the Conners' Continuous Performance Test II (CCPT) and Digit Vigilance Test (DVT) in persons with chronic stroke. METHODS AND PROCEDURES Thirty-nine persons with stroke participated in this study. The participants were twice administered both the CCPT and DVT over a 1-week interval. RESULTS The CCPT performance was reported by two error measures (i.e. Omissions and Commissions) and three time measures (i.e. Hit Reaction Time, Hit Reaction Time Standard Error and Variability of Standard Error). These five measures of the CCPT had good-to-excellent test-re-test reproducibility (ICCs = 0.70-0.90) and limited substantial random measurement errors (SEM% = 7.6-75.2%). Only the Commissions demonstrated substantial practice effects (Cohen's effect size d = 0.38). The DVT had two indicators: the Total Error measure had moderate reproducibility (ICC = 0.55), substantial practice effects (d = 0.30) and random measurement errors (SEM% = 60.8%); the Total Time measure showed excellent reproducibility (ICC = 0.91), less practice effects (d = 0.10) and limited random measurement errors (SEM% = 10.1%). CONCLUSION Only the time measures (i.e. Hit Reaction Time for the CCPT and Total Time for the DVT) had satisfactory test-re-test reliability in persons with chronic stroke, which implies that the time measures are good indicators of sustained attention on both tests.

Abstract
Practice effects in serial neuropsychological assessment have led to the use of alternate forms to measure change in cognitive functioning. The construct validity of three variants of the Trail Making Test was explored over a 3-week period in a sample of 158 undergraduate students. Using confirmatory factor analysis, a two-factor (sequencing-shifting) model was identified to best represent the data. Latent means structural analysis indicated the absence of order effects, lending support for the construct validity of the three tests. The study provides evidence that the three tests can be offered as potential alternative instruments in serial assessment.

Abstract
BACKGROUND Older drivers have higher rates of crashes per mile driven compared with most other drivers, and these crashes result in greater morbidity and mortality. Various aspects of cognition, particularly visual attention, have been linked with crash risk among older individuals. The current study was designed to specify those cognitive variables associated with specific on-road driving behaviors in a sample of older, nonclinic-referred individuals. METHODS 35 community-residing active drivers aged 72 years and older (M = 80) underwent a standardized, on-road driving evaluation involving parking lot maneuvers, and urban, suburban, and highway driving. They were also administered tests of visual attention, executive function, visuospatial cognition, and memory. RESULTS Driving score was significantly correlated with visual attention, visual memory, and executive function. Visual attention was associated with 25 of 36 driving behaviors, including those involving scanning the environment, interaction with traffic or pedestrians, and distance judgments. Executive function and visual memory were associated with fewer maneuvers, most of which were a subset of maneuvers that correlated with visual attention. CONCLUSIONS Visual attention, a cognitive function involving search, selection, and switching, plays an important role in driving risk among older drivers. In the current study, key driving maneuvers involving interaction with other vehicles/pedestrians, such as yielding right of way and negotiating safe turns or merges, have the greatest association with visual attention. Specification of both the cognitive risk factors and their impact on problematic driving maneuvers may provide guidelines for developing targeted interventions to reduce risk among older adults.
