Aviation Pilots

Abstract Objective Neuropsychological evaluations are mandated by the Federal Aviation Administration (FAA) to ensure that pilots with certain known or suspected medical/neurological or psychiatric conditions do not have neurocognitive sequelae that would impair their ability to safely carry out their responsibilities (Federal Aviation Administration, 2020). However, intact pilots’ performance on cognitive measures appears unique compared to the general population (Causse, Dehias, Arexis, & Pastor, 2011). In an effort to make appropriate comparisons, the current study thus presents normative data on the FAA core neuropsychological test battery. Method Sixty-three aviation pilots (age 25–62, M = 44.9, SD = 0.235) underwent neuropsychological testing using the FAA core battery following referral for alcohol utilization. All participants were considered to be cognitively intact at the time of their evaluations. Results Participants’ average IQ on the Wechsler Adult Intelligence Scale 4th edition (WAIS-IV) fell in the Superior range using traditional norms (M = 125.29, SD = 10.04). Pilots performed better than “average” across a number of neuropsychological measures. For example, pilots completed Trails-A in 19.38 seconds (SD = 4.10) and Trails-B in 40.73 seconds (SD = 10.56), which is approximately 10 seconds faster than average among individuals aged 35–44 years. Meanwhile, pilots recalled an average of 15.08 out of 16 words on the California Verbal Learning Test Version 2 (CVLT-II) short delay and 15.34 words on the CVLT-II long delay. Conclusion(s) This study provides comparison data for future neuropsychological evaluations of pilots with alcohol concerns. The data suggests that pilots generally outperform the civilian population across neuropsychological tests.

Abstract Objective Prior research revealed that processing speed predicts nonverbal learning in healthy older adults (Tam & Schmitter-Edgecombe, 2013). This study aims to examine the role of processing speed in both verbal and nonverbal learning in a clinical sample. We expect that processing speed will lend the most variance to the initial learning trials. Method Records from 718 patients were reviewed (mean age = 74). Hierarchical regression analyses were conducted using Brief Visuospatial Memory Test –Revised (BVMT-R) and Hopkins Verbal Learning Test –Revised (HVLT-R) learning trials as outcome variables. Demographics were entered in a first step followed by BVMT-R copy or Wechsler Adult Intelligence Scale (WAIS-IV) Digit Span –longest digit span forward raw score, to account for visuoconstruction or simple auditory attention for nonverbal and verbal learning outcomes respectively. A processing speed composite of sample-standardized raw scores was entered in a final step. Results Processing speed accounted for 5.4% of the variance in BVMT-R trial 1, 7.5% of the variance in trial 2, and 8.5% of the variance in trial 3, all p < .001. Processing speed accounted for 6.6% of the variance in HVLT-R trial 1, 11.1% of the variance in trial 2, and 11.5% of the variance in trial 3, all p < .001. Conclusions Processing speed significantly predicted all verbal and nonverbal learning trials. Contrary to our hypotheses, processing speed actually had a greater contribution during subsequent learning trials. These findings have implications for evaluating memory performance in patients with syndromes where processing speed is typically affected (e.g., cerebrovascular disease, Parkinson’s disease).

Abstract Objective The present study investigated frequency and 12-month persistence of discrepant Clinical Dementia Rating (CDR) and comprehensive neuropsychological assessment ratings of impairment. Methods We examined CDR and neuropsychological test scores from year 1 and 2 visits of 162 adults enrolled in a longitudinal observational study. Neuropsychological measures included Wide Range Achievement Test, American National Adult Reading Test, Rey Auditory Verbal Learning Test, Brief Visuospatial Memory Test-Revised, Dementia Rating Scale 2nd edition, Boston Naming, Verbal Fluency/Color Word Interference from the Delis-Kaplan Executive Function System, Judgment of Line Orientation, Trail Making Test, Symbol Digit Modalities Test, and Digit Span/Letter Number Sequencing from The Wechsler Adult Intelligence Scale 4th edition. Discrepancies were defined as: CDR = 0 and 2 test impairments, CDR = 0.5 and &gt; 5 or 0 impairments, CDR = 1 and 0 impairments. Results Including all test domains, 40.1% of participants in year 1 and 44.3% in year 2 showed discrepancies. 69% maintained this discrepancy at year 2 and 68% of these showed no change in discrepancy type. Considering only memory tests, 37% of participants in year 1 and 28.4% in year 2 showed discrepancies, with 45% maintaining at year 2 (74% showing no change in discrepancy type). A majority of discrepancies observed in both years 1 and 2 revealed the CDR was under reporting impairment compared to the neuropsychological battery year. Conclusions The results provide evidence that within our study population, impairment as rated by the CDR frequently does not match the level of measured cognitive impairment and this observation is stable year to year.

Abstract Objectives Status epilepticus (SE) may lead to or worsen cognitive dysfunction. Few studies have evaluated magnitude and profile of cognitive dysfunction in patients after SE. Characterization of cognitive deficits may be important for rehabilitation and follow-up. We assessed cognitive function in a consecutive, non-selected group of relatively healthy survivors with a comprehensive neuropsychological test battery. Methods A total of 33 patients (24 men, 9 women; mean age 54,9 years, mean education 11,8 years) were tested 1 year after SE with Wechsler Adult Intelligence Scale Fourth edition (WAIS-IV), Rey Auditory Verbal Learning Test, subtests from the Wechsler Memory Scale–Revised, Phonemic and Semantic word list generation, and the Halstead-Reitan Battery. Premorbid IQ was estimated with a Norwegian version of the National Adult Reading Test (NART). Results were compared to published norms. Regression analyses and independent groups t-tests were performed to assess the influence of background variables. Results Mean performance generally was about one standard deviation below average. Full scale IQ (WAIS-IV) was significantly reduced compared to estimated premorbid IQ (NART). Negative influence on cognition of brain lesions visible on computed tomography or magnetic resonance imaging and duration of SE &gt;30 min was shown by group comparisons. Conclusions SE represents a marker for possible cognitive dysfunction, and follow-up with neuropsychological assessment and cognitive rehabilitation seems warranted in most patients. Complex problem-solving abilities with high general sensitivity to brain impairment showed the most prominent reduction. Otherwise, no specific profile of domain affection was found. Structural brain lesions and duration of SE over 30 min represent risk factors for cognitive deficit.

Introduction: We investigated the effect dance experience may have on cortical gray matter thickness and cognitive performance in elderly participants with and without mild cognitive impairment (MCI). Methods: 39 cognitively normal and 48 MCI elderly participants completed a questionnaire regarding their lifetime experience with music, dance, and song. Participants identified themselves as either dancers or nondancers. All participants received structural 1.5-tesla MRI scans and detailed clinical and neuropsychological evaluations. An advanced 3D cortical mapping technique was then applied to calculate cortical thickness. Results: Despite having a trend-level significantly thinner cortex, dancers performed better in cognitive tasks involving learning and memory, such as the California Verbal Learning Test-II (CVLT-II) short delay free recall (p = 0.004), the CVLT-II long delay free recall (p = 0.003), and the CVLT-II learning over trials 1-5 (p = 0.001). Discussion: Together, these results suggest that dance may result in an enhancement of cognitive reserve in aging, which may help avert or delay MCI.

Abstract Objective The purpose of the present study was to compare Wechsler Adult Intelligence Scale-IV (WAIS-IV) Reliable Digit Span (RDS) and Digit Span Age-Corrected Scaled Score (DS-ACSS) sensitivity and specificity, when the effort criterion was determined by between one and five performance validity test (PVT) cut scores. Method Data were collected from 82 adults (18–49) referred for clinical questions of multiple sclerosis, mild traumatic brain injury, and attention deficit hyperactivity disorder. Patients were administered full neuropsychological batteries,with different combinations of PVTs (including Advanced Clinical Solutions Word Choice, Animals raw score, Trails A T-score, Wisconsin Card Sorting Test [WCST; Suhr & Boyer] equation, and California Verbal Learning Test-II Forced Choice). Chi-square and receiver operating characteristic (ROC) analyses were utilized. Results Using established RDS (≤7) and DS-ACSS (≤6) cut scores, specificity was highest (90&37; and 86%, respectively), with equivalent sensitivity (90%), when effort was determined by WCST (Suhr & Boyer) equation failure alone. Related area under the curve for RDS was .90 (CI = .76–1.0) and for DS-ACSS was .88 (CI = .74–1.0). Conclusions In this clinical sample, the highest sensitivity and specificity were observed when the RDS cut score was utilized, and effort was based on the WCST criterion. However, the DS-ACSS cut score resulted in strong sensitivity/specificity combinations across more effort classification groups.

Abstract Objective To examine the utility of the 7/24 Spatial Recall Test (7/24) in the assessment of temporal lobe epilepsy (TLE) patients who have not undergone surgical resection. We hypothesized that patients with right TLE (RTLE) would perform significantly worse on the 7/24 than patients with left TLE (LTLE), but better on measures of verbal memory and naming. Participants and Methods Twenty-one patients with RTLE and 17 patients with LTLE were identified from a larger dataset of 152 epilepsy patients who underwent comprehensive neuropsychological evaluations at Brigham and Women’s Hospital. Exclusion criteria included: 1) Extratemporal, bitemporal, or unclear seizure onset, 2) Post-surgical evaluations, and 3) Co-morbid neurodegenerative or neurological conditions. The Rey Auditory Verbal Learning Test (RVLT) and Boston Naming Test (BNT) and were selected as outcome measures of verbal memory and naming, respectively. Results Independent samples t-tests revealed that patients with RTLE performed significantly worse on the 7/24 delayed recall than LTLE patients (p = 0.026), but there were no significant differences between groups in their 7/24 immediate recall across trials (p = 0.118). As predicted, patients with LTLE performed significantly worse than RTLE patients on the BNT (p = 0.005), however no significant differences were found between groups on the RVLT total learning, short delay, or long delay. Conclusions These findings support the use of the 7/24 for assessing nonverbal memory in patients with TLE, and more specifically, suggest that the 7/24 may be a sensitive measure for detecting lateralized dysfunction of the right temporal lobe in TLE patients.

Background. Considerable research documents an association between pro- and anti-inflammatory markers and Alzheimer's disease (AD), yet the differential relation between these markers and neuropsychological functioning in AD and nondemented controls has received less attention. The current study sought to evaluate the relationship between peripheral markers of inflammation (both pro- and anti-inflammatory) and neuropsychological functioning through the Texas Alzheimer's Research and Care Consortium (TARCC) cohort.Methods. There were 320 participants (Probable ADn=124, Controlsn=196) in the TARCC Longitudinal Research Cohort available for analysis. Regression analyses were utilized to examine the relation between proinflammatory and anti-inflammatory markers and neuropsychological functioning. Follow-up analyses were conducted separately by case versus control status.Results. Proinflammatory and anti-inflammatory markers were found to be associated with neuropsychological testing. Third tertile proinflammatory markers were negatively associated with measures of attention and language, and anti-inflammatory markers were positively associated with measures of immediate verbal memory and delayed verbal and visual memory.Conclusions. These findings support the link between peripheral inflammatory markers and neuropsychological functioning and suggest the utility of examining profiles of inflammatory markers in the future.

In this study we attempted to replicate the classification accuracy of the newly introduced Forced Choice Recognition trial (FCR) of the Rey Complex Figure Test (RCFT) in a clinical sample. We administered the RCFT FCR and the earlier Yes/No Recognition trial from the RCFT to 52 clinically referred patients as part of a comprehensive neuropsychological test battery and incentivized a separate control group of 83 university students to perform well on these measures. We then computed the classification accuracies of both measures against criterion performance validity tests (PVTs) and compared results between the two samples. At previously published validity cutoffs (≤16 & ≤17), the RCFT FCR remained specific (.84–1.00) to psychometrically defined non-credible responding. Simultaneously, the RCFT FCR was more sensitive to examinees’ natural variability in visual-perceptual and verbal memory skills than the Yes/No Recognition trial. Even after being reduced to a seven-point scale (18-24) by the validity cutoffs, both RCFT recognition scores continued to provide clinically useful information on visual memory. This is the first study to validate the RCFT FCR as a PVT in a clinical sample. Our data also support its use for measuring cognitive ability. Replication studies with more diverse samples and different criterion measures are still needed before large-scale clinical application of this scale.

AbstractReduced IQ, learning difficulties and poor school performance have been reported in small-for-gestational-age (SGA) subjects. However, few studies include a comprehensive neuropsychological assessment. Our aim was to study neuropsychological functioning in young adults born SGA at term. A comprehensive neuropsychological test battery was administered to 58 SGA subjects (birth weight <10th centile) born at term, and 81 term non-SGA controls (birth weight ≥10th centile). The SGA group obtained significantly (p< .01) lower scores on the attention, executive and memory domains compared to non-SGA controls and showed higher risk of obtaining scores below −1.5SDon the memory domain (odds ratio = 13.3, 95% confidence interval: 1.57, 112.47). At a subtest level, the SGA group obtained lower scores on most neuropsychological tests, with significant differences on 6 of 46 measures: the Trail Making Test 3 (letter sequencing), the Wechsler Memory Scale mental control and the auditory immediate memory scale, the Design Fluency, the Stroop 3 (inhibition) and the Visual Motor Integration (VMI) motor coordination subtest. Young adults born SGA score more poorly on neuropsychological tests compared with non-SGA controls. Differences were modest, with more significant differences in the memory domain.

Psychoactive Substances

Novel psychoactive substances (NPS) are popular “club/party” drugs that first attracted attention in the UK in 2009 and remained legal until the 2016 Psychoactive Substances Act criminalized their distribution. Unlike “traditional” illicit drugs, very little is known about the influence of their analogs on neuropsychological functioning. We characterized the cognitive and emotional profile of NPS/polydrug users using the Cambridge Neuropsychological Test Automated Battery (CANTAB) and EMOTICOM test battery in adult male (aged 20–49 years) recreational users without psychiatric comorbidities (n = 27; “psychonauts”), service users attending a UK specialist “Club Drug” Clinic for problematic use (n = 20) and healthy control volunteers without significant drug-taking histories (n = 35). Tasks were selected to distinguish “hot” cognitive processes that are highly influenced by emotion from “cold” cognitive processes that are largely independent of emotional influence. Both user groups reported significantly higher sensation-seeking traits compared with non-users. Recreational NPS users demonstrated more risk-taking behavior compared with controls and treatment-seeking NPS users showed poorer learning, episodic memory and response inhibition compared with the other two groups. These effects persisted, when controlling for age, intelligence, alcohol and cannabis use severity, nicotine dependence, trait anxiety, depression, childhood adversity, impulsivity, and sensation seeking. Overall, recreational NPS users showed elevated “hot” (emotion-laden) cognition in the absence of “cold” (non-emotional) cognitive deficits, whereas “cold” cognitive dysfunction was pronounced in individuals seeking treatment for problematic NPS use. High trait impulsivity and poor self-control may confer additional risk to NPS/polydrug use severity and separate those seeking treatment from those using NPS recreationally.
