RESUMO
Despite evidence of premature, accentuated and accelerated aging for some age-related conditions such as cardiovascular diseases in people living with HIV (PLHIV), the evidence for these abnormal patterns of aging on neurocognition remains unclear. Further, no systematic review has been dedicated to this issue. Using PRISMA guidelines, we searched standard databases (PubMed, EMBASE, CINAHL and PsycINFO). Articles were included if they analyzed and reported the effect of age on neurocognition among PLHIV as one of their major findings, if they were conducted in the combination anti-retroviral therapy era (after 1996) and published in a peer-reviewed journal in English. Quality appraisal was conducted using the Joanna Briggs Institute (JBI) appraisal tools. To systematically target the abnormal patterns of neurocognitive aging, we define premature cognitive aging as significant interaction effect of HIV status and age on cross-sectional neurocognitive test performance covering both the normal and abnormal performance range; accentuated cognitive aging as significant interaction effect of HIV status and age on cross-sectional neurocognitive impairment (NCI) rate, thus covering the abnormal performance range only; accelerated cognitive aging as significant interaction effect of HIV status and age on longitudinal neurocognitive test performance or incidence of NCI. Because these definitions require an age-comparable HIV-negative (HIV-) control group, when no controls were included, we determined the range of the age effect on neurocognitive test performance or NCI among PLHIV. A total of 37 studies originating from the US (26), UK (2), Italy (2), Poland (2), China (2), Japan (1), Australia (1), and Brazil (1) were included. Six studies were longitudinal and 14 included HIV- controls. The quality appraisal showed that 12/37 studies neither used an age-matched HIV- controls nor used demographically corrected cognitive scores. A meta-analysis was not possible because study methods and choice of neurocognitive measurement methods and outcomes were heterogeneous imposing a narrative synthesis. In studies with an HIV- control sample, premature neurocognitive aging was found in 45% of the cross-sectional analyses (9/20), while accelerated neurocognitive aging was found in 75% of the longitudinal analyses (3/4). There was no evidence for accentuated aging, but this was tested only in two studies. In studies without an HIV- control sample, the age effect was always present but wide (NCI OR = 1.18-4.8). While large sample size (> 500) was associated with abnormal patterns of cognitive aging, most of the studies were under powered. Other study characteristics such as longitudinal study design and higher proportion of older participants were also associated with the findings of abnormal cognitive aging. There is some support for premature and accelerated cognitive aging among PLHIV in the existing literature especially among large and longitudinal studies and those with higher proportion of older samples. Future HIV and cognitive aging studies need to harmonize neuropsychological measurement methods and outcomes and use a large sample from collaborative multi-sites to generate more robust evidences.

People living with HIV (PLWH) report higher rates of cannabis use than the general population, a trend likely to continue in light of recent policy changes and the reported therapeutic benefits of cannabis for PLWH. Therefore, it is important to better understand cannabis-associated effects on neurocognition, especially as PLWH are at heightened risk for neurocognitive impairment. This study aimed to elucidate the effects of a past cannabis use disorder on current neurocognition in a diverse sample of PLWH. This cross-sectional study included 138 PLWH (age M(SD) = 47.28(8.06); education M(SD) = 12.64(2.73); 73% Male; 71% Latinx) who underwent neuropsychological, DSM-diagnostic, and urine toxicology evaluations. One-way ANCOVAs were conducted to examine effects of a past cannabis use disorder (CUD+) on tests of attention/working memory, processing speed, executive functioning, verbal fluency, learning, memory, and motor ability. Compared to the past CUD- group, the past CUD+ group performed significantly better on tests of processing speed, visual learning and memory, and motor ability (p's < .05). Findings suggest PLWH with past cannabis use have similar or better neurocognition across domains compared to PLWH without past use.

OBJECTIVE: Soccer is the most popular sport worldwide and is the only sport where athletes purposely use their head to deflect the ball during play, termed "heading" the ball. These repetitive head impacts (RHI) are associated with worse neuropsychological function; however, factors that can increase risk of injury following exposure to such head impacts have been largely unexamined. The present study provided a novel examination of the modifying role of sleep on the relationship between RHI exposure and neuropsychological function in college-age soccer players. METHODS: Fifty varsity and intramural college soccer players completed questionnaires assessing recent and long-term heading exposure, a self-report measure of sleep function, and a battery of neuropsychological tests. RESULTS: A high level of recent heading exposure was significantly associated with poorer processing speed, independent of concussion history. With reduced sleep duration, a high level of recent heading exposure was related to worse sustained attention. However, with greater hours of sleep duration, heading exposure was related to preserved neuropsychological outcome in sustained attention. CONCLUSIONS: We replicated our earlier finding of an association between recent head impact exposure and worse processing speed in an independent sample. In addition, we found that sleep may serve as a risk or protective factor for soccer players following extensive exposure to head impacts. Ultimately, this study furthers the understanding of factors impacting neuropsychological function in soccer players and provides empirical support for sleep interventions to help ensure safer soccer play and recovery from injury.

OBJECTIVE: This study describes trajectories of cognitive aging among American Indian/Alaskan Native (AI/AN) adults with and without HIV and the role of immunosenescence longitudinally. METHOD: We characterized trajectories of cognitive aging in a sample of 333 AI/AN and 309 non-Hispanic White (NHW) adults who were followed longitudinally for up to 20 years by the HIV Neurobehavioral Research Program (HNRP) across six U.S. research sites. We used growth curve modeling with autoregressive Lag-1 structures and heterogeneous residual variances to assess the role of ethnoracial identity and HIV grouping upon decline in trajectories of cognitive aging. RESULTS: HIV- AI/AN adults demonstrated earlier and steeper decline in normative trajectories of cognitive aging on tasks of processing speed, timed tasks of attention/working memory, executive function, and psychomotor speed in comparison to HIV- NHW adults. Accentuated trajectories of cognitive aging were evident in both HIV+ and HIV+ immunosuppressed groups in comparison to HIV- peers and were primarily driven by the role of immunosenescence. CONCLUSIONS: AI/AN disparities in trajectories of cognitive aging are evident and are likely explained by the interplay of biopsychosociocultural factors, including immunosenescence.

RESUMO
OBJECTIVE: The National Institutes of Health Toolbox Cognition Battery (NIHTB-CB) has both English- and Spanish-language versions producing crystallized and fluid cognition composite scores. This study examined measurement invariance between languages of administration. If established, measurement invariance would indicate that the composite scores measure the same construct across languages and provide scores that can be meaningfully compared and harmonized in future analyses. METHOD: Participants from the NIHTB-CB normative sample included adults tested in English (n = 1,038; M = 49.1 years old, SD = 18.6) or Spanish (n = 408; M = 44.1 years old, SD = 16.7). Participants completed seven NIHTB-CB tests: Two measuring crystallized cognition and five measuring fluid cognition. Each test score was converted to an age-adjusted standard score or demographic-adjusted T score. A two-factor model (i.e., crystallized cognition and fluid cognition factors) was evaluated using confirmatory factor analysis. Measurement invariance was evaluated by fitting the two-factor model for each language of administration and constraining model parameters to be equivalent across languages, testing configural, weak, strong, and strict models. RESULTS: For age-adjusted and demographic-adjusted scores, the two-factor model fit adequately well, and each factor had adequate reliability among English- and Spanish-speaking participants. Strict invariance was established across languages of administration for both age-adjusted and demographic-adjusted scores. CONCLUSIONS: These findings support the harmonization of the English- and Spanish-language NIHTB-CB crystallized and fluid composite scores, indicating that the composite scores measure the same constructs on the same scale. The results support future studies merging data from participants evaluated in both languages. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Host genetic factors may modify the risk of developing HIV-associated neurocognitive impairment (HIV-NCI), and genetic research has the potential to inform novel treatments for HIV-NCI. However, there is a need to better understand the acceptability of genetic testing among distinct populations of people living with HIV at increased risk for HIV-NCI, such as young people living with perinatally acquired HIV (PHIV) in low- and middle-income countries, to gauge the feasibility of genetic research within these populations. This pilot study evaluated the acceptability and feasibility of genetic testing to assess risk of future neurocognitive problems in 50 Thai adolescents and young adults (13-24 years; Meanage = 19.16 [standard deviation = 3.09]; 52% female) with PHIV and demographically similar HIV-negative controls. Participants (25 PHIV; 25 controls) completed a survey assessing acceptability of and concerns about genetic testing and were asked to provide blood samples for genetic testing. Descriptive statistics and blood draw completion rates were produced and calculated. Reported concerns about genetic testing were grouped thematically and tallied. Independent t tests and chi-squares explored demographic differences between participants who reported concerns and peers. Results indicated 46 participants (92%) rated genetic testing as "acceptable" or "completely acceptable." Eight participants (16%) reported concerns about genetic testing. The most common concerns were related to genetic information being shared or misused. Compared with participants without concerns, participants who reported concerns had more years of education and were more likely to have postsecondary schooling. Regarding completion rates, 49 participants (98%) agreed to genetic testing and provided blood samples. Overall, results support the acceptability and feasibility of incorporating genetic testing into research investigating HIV-NCI among adolescents and young adults in Thailand. Findings provide important considerations for planning future genetic studies among young people in Thailand.

INTRODUCTION: The relative neurocognitive effects of the two most common opioid agonist treatments (OAT; buprenorphine and methadone) for opioid use disorder (OUD) are poorly understood. The aim of this systematic review is to examine the neurocognitive effects of OAT (buprenorphine and methadone) and the clinical and sociodemographic characteristics of study samples. METHODS: The research team queried PubMed, PsycINFO and Cochrane Reviews for articles (01/1980-01/2020) with terms related to neurocognitive testing in adults (age ≥ 18) prescribed OAT. The team extracted neurocognitive data and grouped them by domain (e.g., executive functioning, learning/memory), and assessed study quality. RESULTS: The search retrieved 2341 abstracts, the team reviewed 278 full articles, and 32 met inclusion criteria. Of these, 31 were observational designs and one was an experimental design. Healthy controls performed better across neurocognitive domains than OAT-treated persons (buprenorphine or methadone). Compared to those with active OUD, OAT-treated persons had better neurocognition in various domains. However, in seven studies comparing buprenorphine- and methadone-treated persons, buprenorphine was associated with better neurocognition than was methadone, with moderate to large effect sizes in executive functioning, attention/working memory, and learning/memory. Additionally, OAT research underreports clinical characteristics and underrepresents Black and Latinx adults, as well as women. CONCLUSIONS: Findings suggest that compared to active opioid use, both buprenorphine and methadone treatment are associated with better neurocognitive functioning, but buprenorphine is associated with better executive functioning, attention/working memory, and learning/memory. These findings should be interpreted with caution given widespread methodological heterogeneity, and limited representation of ethnoracially diverse adults and women. Rigorous longitudinal comparisons with more diverse, better characterized samples will help to inform treatment and policy recommendations for persons with OUD.

OBJECTIVE: This cross-sectional study investigates the independent and interactive effects of depression and socioeconomic status (SES) on neurocognition in a diverse sample of people with HIV (PWH). METHOD: The sample of 119 PWH (71% Latinx, 27% female) completed comprehensive neurocognitive and psychosocial evaluations and were separated into two groups: those with a history of depression diagnosis (n = 47) and those without (n = 72). RESULTS: The results of regression analyses indicated that lifetime depression was not associated with lower SES nor with worse neurocognitive performance on any neurocognitive outcome. However, a significant main effect of SES was observed on the Hopkins Verbal Learning Test (total), indicating that higher SES was associated with better verbal learning performance (B= .11, SE = .05, p< .02). Lastly, the results revealed an interactive effect of lifetime depression and SES, such that individuals with depression and higher SES performed better on tests of attention/working memory (i.e., WAIS-III Letter-Number Sequencing, B= .08, SE = .04, p< .02; Paced Auditory Serial Addition Test, B= .39, SE = .16, p< .02). CONCLUSIONS: Depression and SES appear to play an important role in the neurocognitive performance of PWH. Specifically, higher SES appears to have a protective effect on attention/working memory among PWH only if they have co-morbid history of lifetime depression.

ABSTRACT: Research suggests that health locus of control (HLOC) is related to important health and neurocognitive outcomes in people living with HIV. However, the role of ethnicity in these relationships remains poorly understood. This study explored the role of HLOC on neurocognition in a diverse sample of 134 people living with HIV (Latinx: n = 96; non-Latinx White: n = 38) who completed comprehensive neurocognitive evaluations and the Multidimensional HLOC Scale-Form C. Results indicate no ethnocultural differences in HLOC beliefs (ps > .05). External HLOC (i.e., chance and powerful others) related to worse neurocognition in the Latinx group and contributed to significant variance in global neurocognition and learning, memory, and verbal fluency, underscoring the role of external HLOC beliefs on neurocognition, particularly for Latinx individuals. Additional research is needed to better characterize the mechanistic relationship between HLOC beliefs and neurocognitive function and to further explore this relationship among other underrepresented populations also disproportionately affected by HIV.

This literature review summarizes the existing research examining the CNS penetration effectiveness (CPE) score and neurocognitive outcomes (i.e., neuropsychological assessment and neurocognitive screening) in HIV+ individuals. Despite the effectiveness of Combined Antiretroviral Therapy (CART) in reducing mortality and morbidity in HIV and controlling viral replication, HIV often persists in the Central Nervous System (CNS), and rates of neurocognitive impairment remain higher than predicted in the post-CART era. The CPE score was developed to rank antiretroviral regimens on their ability to penetrate the CNS and potency in inhibiting the virus, and it has been examined in relation to neurocognitive functioning for over a decade. Based on the results of 23 studies, we conclude that CPE is not as strongly associated with neurocognitive outcomes as initially hypothesized, although higher CPE ARV regimens may be associated with modest, improved outcomes in global neurocognitive functioning, and to a lesser extent attention/working memory and learning/memory. Conclusions, however, are limited by the heterogeneity in study design and methods, and the lack of a more recent CPE metric update. It is recommended that future research in this area employ comprehensive, standardized neuropsychological test batteries and examine domain-level performance, and use the newer 2010 CPE metric, although an updated CPE ranking is urgently needed.

OBJECTIVE: There is an urgent need to make neuropsychological (NP) testing more acceptable, accessible, and culturally salient, particularly for culturally, educationally, and linguistically diverse individuals from countries who may have little-to-no experience with NP testing. In settings with limited resources such as South Africa, unique cultural and contextual factors (e.g., structural inequality, poverty) may impact the experience of NP evaluation. Research in this area is limited and requires further exploration. This qualitative study explores the role of cultural and contextual factors that may impact the experience of NP evaluation in a sample of Xhosa-speaking South African adults. Participant interviews explored the context from which individuals arrived at the NP assessment (e.g., quality of education, understanding of cognitive disorders), and their experience of completing NP tests. METHOD: This qualitative study used data from semistructured interviews to conduct a thematic analysis exploring contextual factors and the experience of completing NP tests for the first time among Xhosa-speaking South African adults (N = 22). Results: Although no participants had prior experience with NP testing, most found testing procedures acceptable. Most participants, however, reported a limited understanding of the purpose of NP testing and cognitive problems. Additionally, some participants reported perceptions and attitudes that could affect test performance, such as misinterpreting standard testing procedures (e.g., no feedback from the examiner, being stopped mid-task) as indicative of poor performance. CONCLUSIONS: This study provided much needed exploration into unique cultural factors that may impact the experience of NP assessment in South Africa, which could bias test performance and interpretation, and may aid the field of cross-cultural NP in better serving culturally and linguistically diverse populations. In these countries, neuropsychologists may need to actively evaluate participants' understanding of NP testing to help foster optimal assessment conditions. They may also need to educate participants on possible causes of cognitive disorders.

Human Immunodeficiency Virus Type-I (HIV) is a health disparities issue that affects culturally and linguistically diverse (CALD) and underrepresented minority populations to a greater degree than non-Hispanic white populations. Neurologically speaking, CALD populations experience worse HIV-related health outcomes, which are exacerbated by inadequate neurocognitive measures, poor normative samples, and the complex interplay of sociocultural factors that may affect test interpretation. Although cross-cultural neuropsychologists are working diligently to correct this gap in the literature, currently, studies examining neurocognitive outcomes among CALD populations are sparse. The most well-studied CALD groups are of African American/Black and Latinx adults in the US, and the chapter therefore focuses on these studies. There is more limited work among other populations in the US, such as Asians, Native Hawaiians, Pacific Islanders, and American Indians/Alaskan Natives, and even fewer studies for many CALD populations outside of the US. For example, HIV neuropsychology data is rare or nonexistent in the First Peoples of Australia and Indigenous People of Canada. It is often not adequately reported in Europe for the migrant populations within those countries or other world regions that have historically large multicultural populations (e.g., South America, Caribbean countries, Asia, and Africa). Therefore, this chapter reviews HIV-related health disparities faced by CALD populations with focus on North American research where it has been specifically studied, with particular attention given to disparities in HIV-Associated Neurocognitive Disorders (HAND). International data was also included for research with focus on First Peoples of Australia and Indigenous People of Canada. The chapter also examines other sociocultural and health factors, including global and regional (e.g., rural versus urban) considerations, migration, and gender. Further, guidelines for incorporating sociocultural consideration into assessment and interpretation of neurocognitive data and HAND diagnosis when working with HIV-positive CALD populations that would be relevant internationally are provided.

OBJECTIVE: The Wechsler Adult Intelligence Scale (WAIS) processing speed subtests are among the most ubiquitous indices of processing speed in the field. The aim of this study was to develop and examine demographically-adjusted normative data for Spanish language versions of the WAIS-III Digit Symbol Coding (DSC) and Symbol Search (SS) subtests for US-dwelling Spanish-speakers living in the US/Mexico border region. METHODS: The sample included 203 healthy participants who were part of the larger Neuropsychological Norms for the US-Mexico Border Region in Spanish (NP-NUMBRS) project (DSC: n = 201; SS: n = 200). RESULTS: Older age and higher education were both related to lower scores on the DSC and SS subtests (all ps < .0001). There were no significant effects for gender (all ps > .05). Raw-to-scaled score conversions were calculated for both subtests, and fractional polynomial equations were derived to compute demographically-adjusted T-scores accounting for age, education, and gender for each subtest and the Processing Speed Index. Published norms for English-speaking non-Hispanic white adults slightly overestimated impairment rates (T-scores <40) on both the DSC and SS subtests, while the norms for English-speaking non-Hispanic Black/African Americans and the new NP-NUMBRS norms Spanish-speakers both yielded impairment rates that fell within expected limits for healthy controls (i.e. 13%-14%). CONCLUSIONS: This study suggests that population-specific normative data can improve the diagnostic validity of these measures for U.S.-dwelling Spanish-speakers living in the US/Mexico border region. Future research is needed to investigate the utility of these norms for other U.S.-dwelling Spanish-speaking subpopulations (e.g. Caribbean, Central American, South American).

OBJECTIVE: This paper summarizes the findings of the Neuropsychological Norms for the U.S.-Mexico Border Region in Spanish (NP-NUMBRS) Project and offers a roadmap for future research. METHODS: The NP-NUMBRS project represents the largest and most comprehensive co-normed neuropsychological battery to date for native Spanish-speaking healthy adults from the U.S. (California/Arizona)-Mexico borderland region (N = 254; ages 19-60 years). These norms provide demographic adjustments for tests across numerous domains (i.e., verbal fluency, processing speed, attention/working memory, executive function, episodic memory [learning and delayed recall], visuospatial, and fine motor skills). CONCLUSIONS: This project: 1) shows that the NP-NUMBRS norms consistently outperformed previously published norms for English-speaking non-Hispanic (White and African-American) adults in identifying impairment; 2) explores the role of Spanish-English bilingualism in test performance; and 3) provides support for the diagnostic validity of these norms in detecting HIV-associated neurocognitive impairment. Study limitations include the limited assessment of sociocultural variables and generalizability (e.g., other Latina/o populations, age limit [19 - 60 years]). Future research is needed to: 1) investigate these norms with U.S.-dwelling Spanish-speakers of non-Mexican heritage and other clinical subpopulations; 2) expand coverage of cognitive domains (e.g. language, visuospatial); 3) develop large normative datasets for children and older Latina/o populations; 4) examine how sociocultural factors impact performance (e.g., bilingualism, acculturation); 5) investigate these norms' diagnostic and ecological validity; and 6) develop norms for neurocognitive change across time. It is hoped that the NP-NUMBRS norms will aid researchers and clinicians working with U.S.-dwelling Spanish-speakers from the U.S.-Mexico borderland to conduct research and evidence-based neuropsychological evaluations in a more culturally responsive and ethical manner.

Antiretroviral therapy (ART) adherence is vital for optimal HIV treatment. However, there is limited ART adherence research on the US Latinx population, who are at increased risk for HIV infection and worse HIV health outcomes. This study examined electronically measured ART adherence (Medication Event Monitoring System) and its association with demographic, clinical, neurocognitive, and sociocultural variables in Latinx and non-Latinx white (NLW) persons living with HIV [PLWH (N = 128)]. Latinx participants demonstrated worse adherence than NLW participants (p = 0.04). Linear regressions revealed different predictors of adherence. Among Latinx participants, recent cocaine use, stress, and, unexpectedly, higher US acculturation predicted worse adherence (ps < 0.05). Among NLW participants, recent cocaine use predicted worse adherence (p < 0.05). Intergroup comparisons within the Latinx group were not conducted due to subsample size. Thus, ethnicity, sociocultural variables, and cocaine use are important considerations for ART adherence, and poor ART adherence may be one pathway explaining worse outcomes in Latinx PLWH. Culturally tailored adherence interventions incorporating substance use treatment, acculturation, and stress management are warranted to improve health outcomes.

The present study examined the social, cognitive, and emotional functioning of persons with schizotypy. Over 2000 undergraduate students were screened for schizotypy with the Schizotypal Personality Questionnaire - Brief over two consecutive semesters. Ninety-two persons with high schizotypy and 22 persons with low schizotypy completed measures of social functioning (Social Adjustment Scale, Social Functioning Scale, MOS Social Support Survey), working memory (Paced Auditory Serial Addition Test, Digit Span, Letter-Number Sequencing, Corsi Block Tapping Test) and empathy (Interpersonal Reactivity Index, Empathy Quotient). Persons with high schizotypy, when compared to their counterparts with low schizotypy, displayed deficits on many indices of social functioning even though differences in working memory and empathy were not observed. The social functioning deficits of persons with high schizotypy included impairments in friendship relations, family relations, interpersonal engagement, and recreational activities. These findings indicate that persons with high schizotypy experience broad deficits in social functioning even when their cognitive and emotional skills are unaffected.
