Objective: Epilepsy disproportionally affects children from Hispanic/Latino backgrounds, particularly among those born outside the U.S. Longstanding health-related disparities associated with ethnicity (e.g. language use) further contribute to gaps in care. Neuropsychologists are beginning to outline best practices when working with non-English speakers; however, the lack of appropriately normed/validated measures for pre-surgical language evaluation is a limiting factor. This report informs practices among neuropsychologists by discussing atypical language organization in a non-English speaker using a multicultural framework and collaborative therapeutic assessment process. Method: The current study presents a 16-year-old, right-handed, monolingual Spanish-speaking, Latina designated female with drug-resistant focal seizures with impaired awareness. Comprehensive presurgical epilepsy workup included: CBC, video EEG, brain MRI, functional MRI, PET, MEG, baseline neuropsychological evaluation by bilingual Spanish-English providers, and Wada testing. Results: Neuropsychological testing revealed the most pronounced deficits in language, working memory, and processing speed domains. Functional MRI showed bilateral language activation, which Wada testing confirmed along with bilateral memory representation. Conclusion: Diagnosis, treatment, surgical intervention, and post-operative status are discussed. The clinical course is examined through a multicultural lens, highlighting limitations in international health services, barriers accessing health care in the U.S., and patient-specific factors that were considered as a part of the clinical decision-making process. Targeted recommendations related to culturally-informed care are offered.

Objective: Altered reactivity to emotional stimuli is common after traumatic brain injury (TBI), which is suggested to reflect difficulties with emotion regulation. While disinhibition is common after moderate-to-severe TBI, limited research has investigated the link between disinhibition and emotional reactivity in this clinical group. The aim of this research, therefore, was to investigate the relationship between disinhibition and TBI to anger provocation.

Method: Thirty-five individuals with moderate-to-severe TBI and thirty-one controls completed an anger induction task. Participants rated their experience of emotions and subjective arousal before and after the induction. Heart rate, respiration and skin conductance were also measured. Disinhibition was measured using the Frontal Systems Behavior Scale.

Results: In the full sample, the mood induction led to increased skin conductance, respiration, and self-reported anger, tension, arousal and negative mood. There were no differences between those with TBI and controls. Disinhibition interacted with the impact of anger provocation on subjective, but not objective, outcomes such that those elevated in disinhibition reported increased feelings of anger and tension in response to the mood induction. Disinhibition did not interact with TBI across any subjective and objective emotional measures examined in response to mood induction.

Conclusions: While anger causes emotional changes for all individuals, these changes are particularly pronounced among those who are disinhibited, irrespective of whether an individual has sustained a TBI. This is an important consideration when examining emotional regulation post-TBI as the degree of disinhibition appears to alter subjective interpretations of emotional events, which could lead to emotion dysregulation.

Objective: Cognitive reserve (CR) is the brain's ability to cope with changes related to aging and/or disease. Originally introduced to explain individual differences in the clinical manifestations of dementia, CR has recently emerged as a relevant construct in stroke and traumatic brain injury (TBI). This systematic review aims to investigate whether CR could predict post-stroke and TBI clinical recovery and rehabilitation outcomes, and how different variables used to estimate CR (i.e., proxies) are related to the prognosis and effectiveness of rehabilitation in these clinical populations. Method: A search was made in Pubmed, Embase, and PsycInfo for articles published until 12 January 2023, following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) protocol guidelines. Results: 31 studies were included after completing all screening stages. Overall, results show that a higher CR was associated with a better prognosis and a more effective rehabilitation in most of the clinical aspects considered: cognitive functioning, functional, occupational, and socio-emotional abilities, as well as psychiatric and neurological scales. Conclusions: A higher CR seems to be associated with a more favorable prognosis and a better rehabilitation outcome after stroke and TBI. Results suggest that CR should be taken into account in clinical practice to make more accurate predictions about recovery and effectiveness of rehabilitation. However, some inconsistencies suggest the need for further investigations, possibly using multiple proxies for CR.

Objective: Research establishing the validity of neuropsychological assessment using telehealth (teleNP) is much needed in pediatric populations. Method: Current analyses compared performances on twelve common neuropsychological measures completed at home via teleNP or in-person during the COVID-19 pandemic in 476 youth (ages 6 to 17, M_age 11.4 ± 3.0). Results: No differences were found on nine measures. In-person performances on three verbal tests were ∼1 scaled score point lower (all p_adjusted <.05). Post-hoc analyses showed that the in-person pandemic performances were comparable to an in-person pre-pandemic cohort (unmasked). Conclusions: Overall, teleNP was comparable to in-person assessment. Results indicate that teleNP administration does not result in substantially different performance in pediatric patients undergoing clinical evaluations.

Objective: For over half a century, studies of rare diseases using in-person cognitive tools have faced challenges, such as long study periods and small sample sizes (e.g. n = 10). The Montreal Cognitive Assessment (MoCA) was widely employed to assess mild cognitive impairment (MCI). We aimed to validate a modified online version of the MoCA in a large sample of a rare disease (population prevalence < .01%). Method: First, we analyzed 20 previous findings (n = 1,377), comparing the MoCA scores between large groups of neurotypically healthy (NH; n = 837) and cerebellar ataxia (CA; n = 540), where studies were conducted in-person. Second, we administered the MoCA in-person to a group of NH (n = 41) and a large group of CA (n = 103). Third, we administered a video conferencing version of the MoCA to NH (n = 38) and a large group of CA (n = 83). Results: We observed no performance differences between online and in-person MoCA administration in the NH and CA groups (p > .05, η² = 0.001), supporting reliability. Additionally, our online CA group had lower MoCA scores than the NH group (p < .001, Hedges' g = 0.68). This result is consistent with previous studies, as demonstrated by our forest plot across 20 previous in-person findings, supporting construct validity. Conclusion: The results indicate that an online screening tool is valid in a large sample of individuals with CA. Online testing is not only time and cost-effective, but facilitates disease management and monitoring, ultimately enabling early detection of MCI.

Objective: Sickle cell disease (SCD) is an inherited hematologic disorder that impacts approximately 100,000 Americans. This disease is associated with progressive organ damage, cerebral vascular accident, and neurocognitive deficits. Recent guidelines from the American Society of Hematology (ASH) recommend cognitive screening with a psychologist to help manage cerebrovascular risk and cognitive impairment in this population. SCD patients benefit from neuropsychology services and several institutions already have programs in place to monitor cognitive risk. Program Description: We describe a longitudinal neurocognitive evaluation program at our institution that serves all patients with SCD, regardless of disease severity or referral question. The Sickle Cell Assessment of Neurocognitive Skills (SCANS) program was established in 2012. We outline the program's theoretical framework, timepoints for evaluation, test battery, logistics, patient demographics, integration with research programming, and multidisciplinary collaboration to support optimal outcomes. Program Outcomes: Our program has provided 716 targeted neuropsychological evaluations for patients over the last decade. Nearly 26% of patients in the program have been followed longitudinally. The most common diagnoses generated across cross-sectional and longitudinal evaluations include cognitive disorder (n = 191), attention-deficit/hyperactivity disorder (n = 75), and specific learning disorder (n = 75). Approximately 87% of patients who participated in SCANS during late adolescence successfully transitioned from pediatric to adult care. Conclusion: We discuss considerations for developing programming to meet the needs of this population, including tiered assessment models, timing of evaluations, scope, and reimbursement. Program models that utilize prevention-based tiered models or targeted evaluations can assist with serving large volumes of patients.

Objective: The coronavirus disease-2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has had a profound global impact on individual health and well-being in adults and children. While most fully recover from COVID-19, a relatively large subgroup continues to experience persistent physical, cognitive, and emotional/behavioral symptoms beyond the initial infection period. The World Health Organization has termed this phenomenon "Post-COVID-19 Condition" (PCC), better known as "Long COVID." Due to the cognitive and psychosocial symptoms, neuropsychologists often assess and recommend treatment for individuals with Long COVID. However, guidance for neuropsychologists' involvement in clinical care, policy-making, and research has not yet been developed. The authors of this manuscript convened to address this critical gap and develop guidance for clinical neuropsychologists working with patients presenting with Long COVID. Method: Authors include pediatric and adult neuropsychologists with expertise in Long COVID and behavioral health. All authors have been engaged in clinical and research efforts examining the impact of COVID-19. Authors summarized the literature-to-date pertinent to the neuropsychiatric sequelae of Long COVID and developed guidance for neuropsychologists working with individuals with Long COVID. Conclusions: Research findings regarding neuropsychiatric symptoms associated with Long COVID are mixed and limited by methodological differences. As they practice and conduct research, neuropsychologists should remain mindful of the evolving and tenuous nature of the literature.

Objective: The current study examined the longitudinal relationship between cognitive reserve (CR), depression, and executive function (EF) in a cohort of older adults. Methods: 416 participants were selected from the Wisconsin Registry for Alzheimer's Prevention. They were native English speakers, aged ≥50+, and cognitively unimpaired at baseline, with no history of neurological or other psychiatric disorders aside from depression. Depression was assessed with the 20-item Center for Epidemiologic Studies Depression Scale (CES-D). A composite score, based on the premorbid IQ (WRAT-3 Reading subtest) and years of education was used to estimate CR. Another composite score from four cognitive tests was used to estimate EF. A moderation analysis was performed to evaluate the effects of CR and Depression on EF at follow-up after controlling for age, gender, and APOE risk score. Moreover, a multinomial logistic regression was used to predict conversion to Mild Cognitive Impairment (MCI) from the healthy baseline. Results: The negative relationship between depression and EF was stronger in individuals with higher CR levels, suggesting a possible floor effect at lower CR levels. In the multinomial regression, the interaction between CR and depression predicted conversion to MCI status, indicating that lower CR paired with more severe depression at baseline was associated with a higher risk of subsequent impairment. Conclusions: This study sheds light on the intricate relationship between depression and EF over time, suggesting that the association may be influenced by varying levels of CR. Further studies may replicate these findings in clinical populations.

Objective: Latino adults are at increased risk of metabolic syndrome (MetS) and have lower rates of health insurance (HI) coverage. Although inadequate HI coverage and MetS have been independently linked to poor cognition, their potential interactive effects have not yet been examined. The present study explored whether HI moderated the association between MetS and cognition. We hypothesized that Latinos with MetS that did not have HI would demonstrate poorer cognition than those with HI, whereas there would be minimal differences in cognition across HI status in those without MetS. Methods: Cross-sectional data from 805 Latino older adults enrolled in the Health and Aging Brain Study-Health Disparities was utilized. Analysis of covariance adjusting for sociodemographics examined MetS x HI interactions on memory and attention/executive functions composites. Results: Results revealed a significant MetS x HI interaction on memory (F = 4.33, p = 0.037, η_p² = .01); Latino adults with MetS and no HI coverage had worse memory performance than those with MetS who had HI coverage (p = 0.022, η_p² = .01), whereas there was no significant difference in memory between HI coverage groups in those without MetS (p > .05, η_p² = .002). No MetS x HI interaction was observed for the attention/executive functions composite (F = 0.29, p = 0.588, η_p² < .001). Conclusion: Latino older adults with MetS that do not have HI coverage may be at risk for poorer memory outcomes. Increasing the accessibility of HI coverage may help reduce cognitive health disparities in Latino older adults with vascular health comorbidities.

Objective: Hashimoto's encephalopathy (HE), a rare immune-mediated disorder, manifests as altered mental state, cognitive and psychological dysfunction, seizures, and myoclonus. Little is known, however, about the neuropsychological profiles of individuals with HE due to the sparse amount of research. This report overviews HE, summarizes findings from available published neuropsychological evaluations, and details neuropsychological examinations of a 57-year-old White woman with a confirmed HE diagnosis evidencing persistent neuropsychological impairment at two discrete timepoints. Method: An extensive literature search was conducted on PubMed and Google Scholar for studies including neuropsychological evaluations of HE cases. Our neuropsychological evaluation included chart review, diagnostic clinical interview, performance-based neurocognitive assessment, and measures of personality and psychopathology. Results: Our assessment revealed a largely subcortical pattern of neurocognitive impairment and impactful neuropsychiatric symptoms that, together, significantly impacted the patient's quality of life and functional status. The patient's performance improved during a six-month re-evaluation within the domains of cognition, psychological functioning, and functional independence. Conclusions: This article highlights the complexity and possible long-term sequela of HE. Complex medical history (including autoimmune disorders) and psychiatric presentation at onset may be factors related to longer-term cognitive dysfunction. Neuropsychology and psychology can serve important and unique roles in assessing long-term functioning and response to treatment in such cases.
