Method A previously used method of identifying cases of dementia using administrative data was applied to a random sample of 176 cases of Post-9/11 deployed veterans under 65 years of age. Retrospective, cross-sectional examination of EMRs was conducted, using a combination of administrative data, chart abstraction, and review/consensus by board-certified neuropsychologists. Results Approximately 73% of EOD diagnoses identified using existing algorithms were identified as false positives in the overall sample. This increased to approximately 76% among those with mental health conditions and approximately 85% among those with mild traumatic brain injury (TBI; i.e. concussion). Factors related to improved diagnostic accuracy included more severe TBI, diagnosing clinician type, presence of neuroimaging data, absence of a comorbid mental health condition diagnosis, and older age at time of diagnosis. Conclusions A previously used algorithm for detecting dementia using VHA administrative data was not supported for use in the younger adult samples and resulted in an unacceptably high number of false positives. Based on these findings, there is concern for possible misclassification in population studies using similar algorithms to identify rates of EOD among veterans. Further, we provide suggestions to develop an enhanced algorithm for more accurate dementia surveillance among younger populations.","PeriodicalId":197334,"journal":{"name":"The Clinical neuropsychologist","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133668025","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}

In the present study, participants in a multimodal behavioral intervention study were assessed for post-intervention adherence and predictors of adherence. Methods: Participants (N = 272, mean age = 75.04 ± 7.54) diagnosed with amnestic Mild Cognitive Impairment (aMCI) were assigned to intervention groups receiving four out of five behavioral intervention components, including yoga, memory compensation training, computerized cognitive training, support groups, and/or wellness education. Length of the intervention was 10 days, 4 h per day, with post-intervention follow-up at 6, 12, and 18 months. Results: Two-hundred and thirty-seven participants completed the 6-month post-intervention follow-up measures, 228 participants completed the 12-month measures, and 218 participants completed the 18-month measures. Participants fully adhered to a mean of 2 out of the 4 taught intervention components. Eighty-nine percent of participants were at least partially adherent to one or more taught intervention components at 6-, 12-, and 18-month post-intervention follow-up. Physical activity was the most adhered to intervention while group support was the least adhered to intervention across all three follow-up time-points. Higher educational level, higher baseline depressive symptoms, higher baseline global cognitive functioning, and better baseline and concurrent functional abilities were associated post-intervention adherence. Conclusion: Changes in functional abilities are associated with disease progression among persons with aMCI. In the present study, individuals with aMCI who have higher education, higher depressive symptoms, and better baseline functioning abilities are more likely to adhere to behavioral intervention components over time. Post-intervention adherence also associates with concurrent daily function.","PeriodicalId":197334,"journal":{"name":"The Clinical neuropsychologist","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115071433","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}

Identifying those at risk for developing aGVHD is crucial for early intervention. The current study assessed whether scores on a brief cognitive screening measure could identify those that develop aGVHD by 100 days post-HCT. Methods: Participants were 37 patients undergoing allogeneic HCT, assessed prior to transplant, and at 30- and 100-days post-HCT. Of those completing all evaluations, patients were divided into those who did (n = 14) and did not (n = 16) develop aGVHD by day 100 post-HCT. At 100 days post-transplant, groups did not differ on relevant demographic factors, disease, conditioning regimen, relatedness of donor, stem cell source, steroid use, total body irradiation use, human leukocyte antigens (HLA) match, or frequency of infection. Results: At 100 days post-HCT, those with aGVHD performed significantly worse on a working memory measure than those without aGvHD. The presence of aGVHD at day 100 increased significantly with every one standard deviation decrease in working memory from baseline to 30 days post-HCT (odds ratio = 3.08; 95% CI: 1.00–9.36). These findings were observed despite a small sample size and statistically controlling for multiple analyses. Conclusions: While this study is exploratory in nature, and has a small sample size, findings suggest that early detection of working memory declines could coincide with, or signal the development of, aGVHD. Potential etiologies are discussed. Implementing early cognitive screening within the first 30 days post-HCT may be useful in identifying patients at risk for aGVHD.","PeriodicalId":197334,"journal":{"name":"The Clinical neuropsychologist","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127143393","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}

The purpose of the current study was to evaluate the psychometric properties of the VNT and test the feasibility of telephone administration. In addition, regression-based normative data were obtained for the VNT as well as other measures. Method: Eighty-one community-dwelling older adults 61–92 years old (mean = 74.19 years) completed the VNT, the Naming subtests of the Neuropsychological Assessment Battery (NAB), the WIAT-III Sentence Repetition subtest, and the Montreal Cognitive Assessment (MoCA). Results: As evidence of construct validity, the VNT had large correlations with the NAB Naming test and medium correlations with the MoCA and WIAT-III Sentence Repetition test. Cronbach’s alpha in this sample was 0.621. Age, education, and gender were entered into linear regression equations and regression-based normative equations are presented. Lastly, administration of the VNT over the telephone was found to be feasible. Conclusions: The VNT is a valid measure of naming among community-dwelling older adults. Regression-based normative data for the measure will enable its use in the neuropsychological assessment of naming with a wide range of older adults.","PeriodicalId":197334,"journal":{"name":"The Clinical neuropsychologist","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114947812","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}

This study evaluated Wechsler Adult Intelligence Scale, 4th edition (WAIS-IV) Digit Span validity indicators in post-deployment veterans. Method: Neurologically-intact veterans completed structured diagnostic interviews, the WAIS-IV, the Medical Symptom Validity Test (MSVT), and the b Test as part of a larger study. The Noncredible group included individuals who failed either the MSVT or the b Test. Of the total sample (N = 275), 21.09% failed the MSVT and/or b Test. Diagnostic accuracy was calculated predicting group status across cutoff scores on two Digit Span variables, four Reliable Digit Span (RDS) variables, and two Vocabulary minus Digit Span variables. Results: Digit Span age-corrected scaled score (ACSS) had the highest AUC (.648) of all measures assessed; however, sensitivity at the best cutoff of <7 was only 0.17. Of RDS measures, the Working Memory RDS resulted in the highest AUC (.629), but Enhanced RDS and Alternate RDS produced the highest sensitivities (0.22). Overall, cutoff scores were consistent with other studies, but sensitivities were lower. Vocabulary minus Digit Span measures were not significant. Conclusions: Digit Span ACSS was the strongest predictor of noncredible performance, and outperformed traditional RDS variants. Sensitivity across all validity indicators was low in this research sample, though cutoff scores were congruent with previous research. Although embedded Digit Span validity indicators may be useful, they are not sufficient to replace standalone performance validity tests.","PeriodicalId":197334,"journal":{"name":"The Clinical neuropsychologist","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117142024","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}

Methods: Two hundred twenty participants diagnosed with Richardson’s syndrome of PSP (PSP-RS) were evaluated with the RBANS at baseline, six months, and one year with alternate forms. Results: When using dependent t-tests, significant declines were observed on all Indexes of the RBANS from baseline to six months (ps < 0.01). Between six months and one year, significant declines were observed on three Indexes of the RBANS (ps < 0.05). Using existing regression-based change formulae from cognitively intact older adults, these participants with PSP showed significant decline on all RBANS Indexes (ps < 0.01) across one year. Finally, new regression-based change formulae were developed on this sample of individuals with PSP-RS to more precisely evaluate cognitive change in this condition. Conclusion: In this large, longitudinal cohort of participants with PSP-RS, many (but not all) showed notable cognitive decline across six months and one year on the RBANS. The different methods of examining change across time yielded different results, with regression-based methods appearing to more accurately capture decline in this sample. These findings are expected to allow clinicians to more accurately evaluate cognitive trajectories in patients with PSP, as well as make better estimates of prognosis and offer more appropriate treatment recommendations. Such findings are also expected to inform clinical trials as to the changes in cognitive outcomes with this neurological condition.","PeriodicalId":197334,"journal":{"name":"The Clinical neuropsychologist","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115182134","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}

The purpose of this study was to examine the utility of a performance-rating method for assessing awareness of cognitive performance in HD. Method: Persons with manifest HD (n = 54) rated their performance on the daily living tests from the Neuropsychological Assessment Battery (NAB) using a bell curve. We also examined patient/informant-report discrepancies of executive functioning (FrSBe) in a subset (n = 47) of patients and their informants. Results: Patients were able to reliably use our method of categorizing their performance as evidenced by significant correlations between verbal descriptions of their performance and the percentile ratings they indicated on the bell curve. Patients across the range of observed Unified HD Rating Scale motor scale scores rated their performance on the NAB tasks significantly higher than actual performance for both pretest prediction and posttest evaluation ratings. Only patients with more severe motor impairment underestimated their problems relative to informant report on the FrSBe. Conclusions: This is the first study to use a performance-rating method for examining awareness in HD. Patients could reliably use this performance-based bell curve method to provide accurate estimations of their performance and as a group they tended to overestimate performance as has been demonstrated in previous studies. Unlike previous studies using self-report methodology, we also demonstrated decreased awareness in the persons with HD with less severe motor impairment using the performance-rating method, suggesting the two methods may measure different constructs of awareness.","PeriodicalId":197334,"journal":{"name":"The Clinical neuropsychologist","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130998565","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}

This study examined the clinical utility of EDPF scores to detect invalid test performance following traumatic brain injury (TBI). Methods: Participants were 194 U.S. military service members who completed neuropsychological testing on average 2.4 years (SD = 4.0) following uncomplicated mild, complicated mild, moderate, severe, or penetrating TBI (Age: M = 34.0, SD = 9.9). Using TBI severity and PVT performance (i.e., PVT Pass/Fail), participants were classified into three groups: Uncomplicated Mild TBI-PVT Fail (MTBI-Fail; n = 21), Uncomplicated Mild TBI-PVT Pass (MTBI-Pass; n = 94), and Complicated Mild to Severe/Penetrating TBI-PVT Pass (CM/STBI-Pass; n = 79). Seven EDPF measures were calculated by subtracting WAIS-IV obtained index scores from the demographically predicted scores from the Test of Premorbid Functioning (TOPF). Cutoff scores to detect invalid test performance were examined for each EDPF measure separately. Results: The MTBI-Fail group had higher scores than the MTBI-Pass and CM/STBI-Pass groups on five of the seven EDPF measures (p<.05). Overall, the EDPF measure using the Processing Speed Index (EDPF-PSI) was the most useful score to detect invalid test performance. However, sensitivity was only low to moderate depending on the cutoff score used. Conclusions: These findings provide support for the use of EDPF as an embedded PVT to be considered along with other performance validity data when administering the WAIS-IV.","PeriodicalId":197334,"journal":{"name":"The Clinical neuropsychologist","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115986766","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}

Methods: Data were reported on 18,886 participants (58% male) from the NCAA/DoD CARE Consortium. Race, SES, concussion history, estimated repetitive head impact exposure (eRHIE), and academic aptitude (SAT or ACT score) were our predictors of interest. Cognition was measured using ImPACT composite scores. We evaluated the mediating effects of academic aptitude on sociodemographic predictors and eRHIE on ImPACT scores. We then evaluated a football-only subsample and added age of first exposure to football (AFE) to the model. Males, females, and football players were analyzed separately using structural equation modeling. Results: Academic aptitude was associated with Black/African American race, SES, and each of the ImPACT composite scores. There were significant indirect effects of Black/African American race and SES on all ImPACT composite scores. Academic aptitude fully mediated SES effects and either fully or partially mediated race effects. Contrary to expectation, greater concussion history and eRHIE predicted better ImPACT scores. Conclusions: Academic aptitude, a stable indicator of premorbid cognitive function, consistently and most strongly predicted baseline ImPACT scores in collegiate student-athletes. Concussion and eRHIE history demonstrated a small positive, but non-significant, relationship with cognitive scores at the time of college athletic participation.
