Diverse experiences and approaches to tele neuropsychology: Commentary and reflections over the past year of COVID-19.

Objectives: In response to the coronavirus disease 2019 (COVID-19) pandemic, neuropsychologists rapidly adopted teleneuropsychology (TeleNP) services to ensure continued clinical care. Prior to COVID-19, TeleNP was not widely used nor was it included in the majority of traditional practice or training models across graduate, internship, and postdoctoral programs. Out of necessity, the pandemic was a catalyst that promoted greater adoption of TeleNP services. In response, neuropsychological guidelines for modified assessments were developed and further empirical studies have been published. Numerous surveys in response to service delivery changes during COVID-19 now exist, but what follows is a commentary based on neuropsychologists' experiences with adapting clinical practice to TeleNP. Methods: Co-authors represent settings across academic medical centers, Veterans Affairs hospitals, and private practices that serve multiculturally diverse pediatric, adult, and geriatric populations in the United States. Results: The perspectives within this commentary aim to highlight the growth of TeleNP and highlight lessons learned from implementation across practice settings. Conclusions: Our goal is to help foster the development of further empirical studies through candid discussion of various TeleNP experiences and approaches. Through this reflective process, TeleNP presents both opportunities and challenges but it ultimately has potential to reduce healthcare disparities and enhance patient care.

Is formal scoring better than just looking? A comparison of subjective and objective scoring methods of the Rey Complex Figure Test for lateralizing temporal lobe epilepsy.

ObjectiveNeuropsychologists labor over scoring the Rey Complex Figure Test (RCFT), a measure of visuospatial functioning and nonverbal memory. Compelling arguments suggest that pathognomonic signs of the RCFT are observable to the "naked eye." Standard scoring systems are insensitive to lateralizing temporal lobe epilepsy (TLE) and alternative "qualitative" scoring systems are ineffective and time-consuming. Method: We examined accuracy of TLE lateralization using subjective classifications and standard scoring. Participants were 84 TLE patients (53 female; mean age=36yrs) and 46 controls (27 female; mean age = 27.5). The former were classified as right (n = 41) or left (n = 43) TLE by neurologists using EEG and MRI studies. RCFT were scored using standard scoring with cut-offs of z ≤ -2 classified as impaired and were rated as "characteristic" of RTLE (Ugly) or LTLE (Not Ugly) performance by neuropsychologists. Accuracy of seizure lateralization for both methods was examined. Results: Neuropsychologists' ratings accuracy were at or below chance. Standard scoring criteria showed chance or slightly better lateralization prediction. Standard scoring predicted RTLE laterality more accurately than subjective ratings for copy trials; standard scoring was no better at lateralizing RTLE with delays. Subjective ratings were better at distinguishing TLE patients from controls. Conclusion: Findings highlight concerns regarding the usefulness of the RCFT in TLE lateralization, regardless of scoring approach.

Neuropsychological outcomes following supratotal resection for high-grade glioma: a review.

PURPOSE: Supratotal resection (SpTR) of high-grade glioma (HGG), in which surgical removal of the tumor is extended outside the margins of the preoperative radiographic abnormality, has been suggested to improve overall survival (OS) and progression free survival (PFS) in patients harboring tumors of non-eloquent cortex when compared to gross total resection (GTR). While current literature demonstrates these findings without an increase in post-operative complications or neurological deficits, there remains a paucity of data examining the neuropsychological outcomes of SpTR for HGG. As quality of life dramatically influences survival rates in these patients, it is crucial for neurosurgeons, neuro-oncologists, and neuropsychiatrists to understand the behavioral and cognitive outcomes following SpTR, such that optimal treatment strategies can be tailored for each patient. METHODS: We performed a comprehensive review of the available literature regarding survival, neuropsychological, and quality of life (QOL) outcomes following SpTR for HGG. We also review neuropsychological and QOL outcomes following GTR for HGG to serve as a framework for better understanding potential implications of SpTR. RESULTS: While results are limited following SpTR for HGG, available data suggests similar outcomes to those seen in patients undergoing GTR of HGG, as well as low-grade glioma. These include a short-term decline in neuropsychological functioning post-surgically with a return to baseline across most neurocognitive domains occurring within several months. Memory and attention remain relatively diminished at long term follow-up. CONCLUSIONS: Limited data exist examining postoperative cognitive and behavioral outcomes following SpTR for HGG. While the available data suggests a return to baseline for many neurocognitive domains, attention and memory deficits may persist. However, sample sizes are relatively small and have not been examined in the context of QOL and OS/PFS. More rigorous pre- and post-surgical neuropsychological assessment will help shed light on the long-term cognitive and behavioral effects of SpTR in the setting of HGG and inform clinical care and counseling when SpTR is considered.

Assessment Trends Among Neuropsychologists Conducting Sport-Related Concussion Evaluations.

Neuropsychologists regularly conduct sport-related concussion (SRC) evaluations, although research has not tracked these assessment practices. As part of a survey of neuropsychological test usage, we analyzed data from 215 neuropsychologists who conduct SRC evaluations. Only 15% reported conducting baseline assessments of athletes as part of a sports program and 92% evaluate athletes' post-concussion without baseline data. The majority of respondents use a full battery, considered the most reliable approach for assessing concussion symptoms in athletes. Only 6% use computerized tests exclusively (>50% ImPACT). We discuss the implications of these results and address challenges faced by neuropsychologists who perform SRC evaluations.

The Association between High Neuroticism-Low Extraversion and Dual-Task Performance during Walking While Talking in Non-demented Older Adults.

The Walking While Talking (WWT) dual-task paradigm is a mobility stress test that predicts major outcomes, including falls, frailty, disability, and mortality in aging. Certain personality traits, such as neuroticism, extraversion, and their combination, have been linked to both cognitive and motor outcomes. We examined whether individual differences in personality dimensions of neuroticism and extraversion predicted dual-task performance decrements (both motor and cognitive) on a WWT task in non-demented older adults. We hypothesized that the combined effect of high neuroticism-low extraversion would be related to greater dual-task costs in gait velocity and cognitive performance in non-demented older adults. Participants (N=295; age range,=65-95 years; female=164) completed the Big Five Inventory and WWT task involving concurrent gait and a serial 7's subtraction task. Gait velocity was obtained using an instrumented walkway. The high neuroticism-low extraversion group incurred greater dual-task costs (i.e., worse performance) in both gait velocity {95% confidence interval (CI) [-17.68 to -3.07]} and cognitive performance (95% CI [-19.34 to -2.44]) compared to the low neuroticism-high extraversion group, suggesting that high neuroticism-low extraversion interferes with the allocation of attentional resources to competing task demands during the WWT task. Older individuals with high neuroticism-low extraversion may be at higher risk for falls, mobility decline and other adverse outcomes in aging.

Neurocognitive Profile of a Woman with Susac's Syndrome: Further Evidence of Cognitive Variability.

OBJECTIVE: Susac's syndrome is a rare autoimmune disease characterized by encephalopathy, retinal artery occlusions, hearing loss, and lesions to the corpus callosum. To date, only four papers (five cases) have described the neuropsychological effects of the syndrome. Extant case reports of Susac's syndrome have documented varying levels of cognitive impairment; some studies have identified diffuse cerebral dysfunction, while others describe more focal impairments in attention, memory, and executive functioning. METHOD: The goal of this case study was to provide comprehensive neurocognitive data obtained from another case of confirmed Susac's syndrome. As such, we present the case of a 42-year-old woman with a two-year history of Susac's syndrome. At the time of the neuropsychological evaluation, the patient described ongoing difficulties with memory, word-finding problems, problems with math, and poor problem-solving. Physical/sensory changes included hearing loss, tinnitus, and migraines. RESULTS: Neuropsychological test results revealed the patient to be a woman of estimated average to high average premorbid intellect who exhibited a number of focal inefficiencies in the context of a generally intact profile. Particular cognitive weaknesses emerged on select tasks involving visuoconstruction, encoding of a wordlist, and bilateral speeded finger oscillations. She also committed three failures to maintain set on a task of cognitive flexibility. There was no evidence of memory deficits. CONCLUSIONS: Our findings provide further evidence of cognitive interindividual variability in a confirmed case of Susac's syndrome.

Relationship between executive functions and motor stereotypies in children with Autistic Disorder.

This study reports on the relationship between motor stereotypies and impairments in executive functions (EF) in children with Autistic Disorder (AD) and in children with Developmental Language Disorders (DLD). We hypothesized that low EF performance would predict higher frequency and longer durations of stereotypies in the AD group only. Twenty-two children (age range = 7-9 years, 6 months, girls = 5) with AD were recruited from a longitudinal multi-site study and compared to twenty-two non-autistic children with DLD (age range = 7-9 years, 6 months, girls = 5). The two groups were matched on non-verbal IQ and demographic characteristics. Frequency and duration of stereotypies were coded from videotaped semi-structured play sessions. EF measures included the Wisconsin Card Sorting Task (WCST) Categories, Wechsler Intelligence Scale for Children-Revised (WISC-R) Mazes, and Stanford-Binet Fourth Edition (SB-IV) Matrices. The scores for frequency and duration of stereotypies were higher in the AD group. Separate linear regressions revealed that group status, EF, and their interactions predict stereotypies. Specifically, lower EF scores predicted higher frequencies and longer durations of stereotypies in the AD group only. Analyses controlled for age, gender, and parent education. Findings suggest that in AD, EF impairments and stereotypies may be linked to shared brain pathways.
