Abstract
OBJECTIVE Low health literacy is common among people with epilepsy (PWE) and may play an important role in disease management and outcomes. The current study evaluated whether health literacy is related to cognition, health, and everyday functioning in PWE. METHODS This cross-sectional, correlational study included 25 demographically comparable healthy adults retrospectively matched to a consecutive series of 89 PWE presenting for neuropsychological evaluation in a surgical setting and who completed the Newest Vital Sign and Brief Health Literacy Screener. The PWE also completed a comprehensive neuropsychological battery and measures of quality of life and everyday functioning. RESULTS PWE had significantly lower health literacy as compared to healthy adults (ps < 0.05) at a medium-to-large effect size. In analyses covarying for education and oral word reading literacy in the PWE sample, lower health literacy was independently associated with bilateral seizure onsets, greater antiseizure medication burden, poorer performance on measures of memory and information processing speed, and difficulties with self-care (ps < 0.05). SIGNIFICANCE Findings suggest that PWE are at risk for low health literacy, which may be partly attributable to disrupted brain-behavior relationships and contribute to poorer everyday functioning. Future studies are needed to identify effective methods to support and improve health literacy in PWE.

Abstract
OBJECTIVE People with HIV (PWH) can demonstrate elevated cognitive intraindividual variability (IIV-dispersion) that is associated with everyday functioning problems. Higher IIV-dispersion is theorized to reflect lapses in executive aspects of cognitive control, but few studies have directly evaluated this possibility. METHOD 72 PWH completed the Cogstate and clinical measures of executive functions, psychomotor speed, and episodic memory. IIV-dispersion was calculated with the coefficient of variation (CoV) from six age-adjusted Cogstate subtest scores. RESULTS Multiple regression showed that the three domain-level cognitive predictors explained 8% of the variance in Cogstate CoV (p = .03). Within this model, poorer executive functions were moderately associated with higher Cogstate CoV (p = .01), but the psychomotor and episodic memory domains were not (ps > .05). CONCLUSIONS Findings align with cognitive theory in demonstrating IIV-dispersion is uniquely associated with independent measures of executive functions among PWH. Future experimental and mechanistic studies are needed to determine the precise executive aspects of IIV-dispersion.

Abstract
INTRODUCTION Episodic memory disruptions in epilepsy stem from shared neurocircuitry. While prior research has focused on retrospective memory (RM), prospective memory (PM; i.e. remembering to remember) also deserves consideration given its critical role in the management of daily activities. The current investigation assessed whether PM is associated with disability and quality of life in people with epilepsy. METHODS This cross-sectional, correlational study included a consecutive series of 50 people with epilepsy presenting for neuropsychological evaluation who completed the Royal Prince Alfred Prospective Memory Test (RPA) and Prospective and Retrospective Memory Questionnaire (PRMQ) and 63 demographically comparable healthy adults. The participants with epilepsy also completed clinical measures of neuropsychological ability and questionnaires assessing disability and quality of life. RESULTS People with epilepsy had significantly more frequent memory symptoms as compared to healthy adults at a very large effect size. Worse mood was associated with lower PM ability at a medium effect size and more frequent PM symptoms at a large effect size. A hierarchical linear regression indicated that PM explained 52% of the variance in disability and 43% of the variance in quality of life after accounting for RM ability. CONCLUSIONS PM is associated with poorer everyday functioning among people with epilepsy and shows evidence of incremental value beyond RM ability in that regard. Future studies are needed to understand the complex pathways from PM to functional limitations to inform clinical intervention.

Abstract
People with HIV (PWH) are susceptible to neurocognitive, physical, and mental health problems that may decrease their likelihood of experiencing successful aging. This cross-sectional, retrospective study estimated the extent to which health literacy is associated with successful aging among 116 older PWH and 60 persons without HIV. Successful aging was defined using indicators of biological health, cognitive efficiency, mental health, and productivity. Health literacy was measured using the Rapid Estimate of Adult Literacy in Medicine, Newest Vital Sign, Brief Health Literacy Screening, and Beliefs Related to Medication Adherence. A series of logistic regressions covarying for education showed that better health literacy was associated with a higher frequency of successful aging among older PWH. Older PWH were approximately three times less likely to experience successful aging as compared to older adults without HIV. Future studies may examine whether improving health literacy among younger PWH increases the likelihood of successful aging.

Abstract
BACKGROUND Executive dysfunction, which is common among persons with HIV (PWH), can have an adverse impact on health behaviors and quality of life. Intra-individual variability (IIV) is a measure of within-person variability across cognitive tests that is higher in PWH and is thought to reflect cognitive dyscontrol. OBJECTIVE To assess whether cognitive IIV in the laboratory is associated with self-reported executive dysfunction in daily life among older PWH. METHOD Participants included 71 PWH aged ≥50 years who completed six subtests from the Cogstate battery and two subscales from the Frontal Systems Behavior Scale (FrSBe; self-report version). Cognitive IIV was calculated from the Cogstate as the coefficient of variation derived from age-adjusted normative T scores. RESULTS Cognitive IIV as measured by the Cogstate showed a significant, positive, medium-sized association with current FrSBe ratings of executive dysfunction but not disinhibition. CONCLUSION Higher cognitive IIV in the laboratory as measured by the Cogstate may be related to the expression of HIV-associated symptoms of executive dysfunction in daily life for older PWH.

Abstract
Introduction: Gay and bisexual men (GBM) account for the highest rates of incident infection with HIV in the U.S., and experience social, systemic barriers to accessing and engaging in healthcare services. Interacting with healthcare providers can be a complex process for some GBM with HIV disease. The current study examined the contributions of cognition and health literacy to perceived interactions with healthcare providers among GBM with HIV disease. Methods: The sample included 100 adults with HIV disease (ages 24-75) who identified as GBM. All participants completed the Dealing with Health Professionals subscale of the Beliefs Related to Medication Adherence survey, as well as the Cogstate neuropsychological battery, self-report measures of cognitive symptoms, and well-validated measures of health literacy. Results: Worse performance-based cognition and subjective cognitive symptoms were both associated with perceived difficulties dealing with healthcare providers, but these associations were fully mediated by lower health literacy. Conclusion: Health literacy may play a role in the association between poorer cognitive functioning and difficulties navigating healthcare interactions among GBM with HIV disease. Further studies are needed to determine whether cognitive approaches to enhancing the access, understanding, and use of health information in GBM with HIV disease improves healthcare interactions and outcomes.

Abstract
Dementia is a syndrome characterized by cognitive and neuropsychiatric symptoms associated with progressive functional decline (FD). FD is a core diagnostic criterion for dementia, setting the threshold between its prodromal stages and the full-blown disease. The operationalization of FD continues to generate a great deal of controversy. For instance, the threshold of FD for the diagnosis of dementia varies across diagnostic criteria, supporting the need for standardization of this construct. Moreover, there is a need to reconsider how we are measuring FD to set boundaries between normal aging, mild cognitive impairment, and dementia. In this paper, we propose a multidimensional framework that addresses outstanding issues in the assessment of FD: i) What activities of daily living (ADLs) are necessary to sustain an independent living in aging? ii) How to assess FD in individuals with suspected neurocognitive disorders? iii) To whom is the assessment directed? and iv) How much does FD differentiate healthy aging from mild and major neurocognitive disorders? Importantly, the To Whom Question introduces a person-centered approach that regards patients and caregivers as active agents in the assessment process of FD. Thus, once impaired ADLs have been identified, patients can indicate how significant such impairments are for them in daily life. We envisage that this new framework will guide future strategies to enhance functional assessment and treatment of patients with dementia and their caregivers.

Abstract
Deficits in episodic verbal memory are commonly observed in persons with HIV (PWH) disease, in whom they are characterized by dysregulation of the executive aspects of encoding and retrieval and adversely impact everyday functioning. Deficits in episodic visual memory are also apparent in PWH, but we know less about their cognitive architecture. This study used the Boston Qualitative Scoring System (BQSS) for the Rey-Osterrieth Complex Figure (ROCF) to examine visual learning and recall in 43 individuals without HIV and 141 PWH who completed a full research neuropsychological, psychiatric, and medical assessment. A mixed model covarying for education and estimated verbal IQ showed that participants with HIV-associated neurocognitive disorders (HAND) performed worse than PWH without neurocognitive disorders and HIV- participants at comparable medium-to-large effect sizes across the Copy, Immediate, and Delayed trials of the BQSS-ROCF, suggesting a primary encoding deficit. A component process analysis of the BQSS-ROCF Copy Trial revealed that participants with HAND had specific difficulties with configural accuracy, cluster accuracy, and cluster placement. Within the PWH sample, measures of motor coordination and executive functions emerged as independent predictors of BQSS-ROCF Copy Trial performance. Findings extend prior research by showing that HAND may be associated with a primary encoding deficit for complex visuomotor learning and memory tasks that is driven by a combination of visuospatial, motor, and executive difficulties.

Abstract
Reliable and valid neurocognitive (NC) test batteries that assess multiple domains of cognitive functioning are vital tools in the early detection of HIV-associated NC impairment. The HIV Neurobehavioral Research Center's International Neurobehavioral Battery (HNRC Battery) is one such diagnostic tool and has shown cultural validity in several international neuroHIV studies. However, no published norms are currently available for the full HNRC Battery in South Africa. To accurately interpret NC test results, appropriate reference norms are required. In light of this challenge, data were collected from 500 healthy, HIV-uninfected participants to develop demographically corrected South African norms. When demographically corrected United States of America (U.S.) norms were applied to the performance scores of our neurologically intact, HIV-negative sample, an impairment rate of 62.2% was observed compared to a 15.0% impairment rate when the newly generated South African norms were applied. These results reiterate the findings of other low- and middle-income countries, highlighting the need for localized, country-specific norms when interpreting NC performance.

Abstract
ABSTRACT Apathy is common in persons with HIV (PWH) and has been associated with a variety of health outcomes. We examined the association between apathy and self-efficacy for health care provider interactions in 142 PWH. A composite score comprised of the apathy subscale of the Frontal Systems Behavioral Scale and the vigor-activation scale of the Profile of Mood States was used to measure apathy. Self-efficacy for health care provider interactions was measured using the Beliefs Related to Medication Adherence - Dealing with Health Professional subscale. Higher levels of apathy were associated with lower self-efficacy for health care provider interactions at a medium effect size, independent of mood disorders, health literacy, and neurocognition. Findings suggest that apathy plays a unique role in self-efficacy for health care provider interactions and support the importance of assessment and management of apathy to maximize health outcomes among PWH.

Abstract
BACKGROUND Modifiable lifestyle factors such as engagement with technology may be beneficial to cognition in older adults, but we know little about these relationships in older persons with chronic medical conditions. AIMS The current study examined the association between computer use frequency and cognition in younger and older adults with and without HIV disease. METHODS Participants included 110 older persons with HIV (pwHIV; age ≥ 50 years), 84 younger pwHIV (age ≤ 40 years), 76 older HIV-, and 66 younger HIV- adults who completed a comprehensive medical, psychiatric, and cognitive research assessment. Demographically adjusted scores were derived from a well-validated clinical battery of performance-based neuropsychological tests. Participants also completed self-reported measures of cognitive symptoms in daily life and the Brief Computer Use and Anxiety Questionnaire (BCUAQ). RESULTS Older age was associated with less frequent computer use among persons with and without HIV disease. More frequent computer use was strongly and independently related to better cognitive performance, particularly in higher order domains (e.g., episodic memory and executive functions) and among the older seronegative adults. A small, univariable correlation between more frequent computer use and fewer cognitive symptoms in daily life was observed in the full sample, but that relationship was better explained by computer-related anxiety and HIV/age study group. DISCUSSION These findings add to the existing literature that suggests regular engagement with digital technologies may have a beneficial impact on cognitive functioning, consistent with the technological reserve hypothesis.

Abstract
Background Little is known about the prevalence of undiagnosed cognitive impairment and its impact on instrumental activities of daily living (IADL) among people with HIV (PWH) in primary care. Methods PWH were recruited from an integrated health care setting in the United States. PWH were eligible for recruitment if they were ≥50 years old, taking antiretroviral therapy (ie, ≥1 antiretroviral therapy [ART] prescription fill in the past year), and had no clinical diagnosis of dementia. Participants completed a cognitive screen (St. Louis University Mental Status exam) and a questionnaire on IADL (modified Lawton-Brody). Results Study participants (n = 47) were mostly male (85.1%), 51.1% White, 25.5% Black, 17.0% Hispanic, and the average age (SD) was 59.7 (7.0) years. Overall, 27 (57.5%) participants were categorized as cognitively normal, 17 (36.2%) as having mild cognitive impairment, and 3 (6.4%) as having possible dementia. Of the 20 participants with mild cognitive impairment or possible dementia, 85.0% were men, the average age (SD) was 60.4 (7.1) years; 45.0% were White, 40.0% were Black, 10.0% were Hispanic, and 30.0% reported difficulty with at least 1 IADL. Most (66.7%) attributed difficulty with IADL primarily (33.3%) or in part (33.3%) to cognitive problems. Conclusions Undiagnosed cognitive impairment is frequent among ART-treated PWH, with possible elevated risk among Black PWH, and may be accompanied by difficulty with IADL. Efforts are needed to optimize identification of factors contributing to cognitive and IADL difficulties among ART-treated PWH in primary care.

Abstract
Many people living with human immunodeficiency virus (HIV) (PLWH) experience cognitive decline that impairs everyday functioning. Cognitive training approaches, such as speed of processing (SOP) training, may reduce the impact of HIV-Associated Neurocognitive Disorder (HAND) on everyday functioning. In this experimental design study called the Think Fast Study, 216 participants age 40 and older with HAND or borderline HAND were randomized to one of three groups: (1) 10 h of SOP training (n = 70); (2) 20 h of SOP training (n = 73); or (3) 10 h of Internet Navigation Control Training (a contact control group; n = 73). Participants completed several everyday functioning measures at baseline, posttest, and year 1 and year 2 follow ups, which included: (a) Modified Lawton and Brody Activities of Daily Living (ADL) Questionnaire; (b) Timed Instrumental Activities of Daily Living (TIADL) Test; (c) Patient's Assessment of Own Functioning (PAOFI); (d) Medication Adherence Questionnaire (MAQ); and (e) Medication Adherence Visual Analog Scale (VAS). Linear mixed-effect models and generalized estimating equation models were fitted to estimate between group differences at all follow-up time points. At follow-up timepoints, those in the 10-h and 20-h training groups had better scores on medication adherence measures (MAQ and VAS) than those in the control group, with effects (Cohen's d) ranging 0.13-0.41 for MAQ and 0.02-0.43 for VAS. In conclusion, SOP training improved some indicators of everyday functioning, specifically medication adherence; however, the therapeutic effects diminished over time. Implications for practice and research are posited.

Abstract
Depression and cardiovascular disease are common and associated with one another in HIV disease. This study aimed to determine the frequency and everyday functioning implications of the clinical syndrome of vascular depression among people living with HIV (PLWH). Participants in this cross-sectional study included 536 PLWH and 272 seronegative individuals who completed a biomedical and psychiatric research evaluation. Vascular depression was operationalized as the current presence of: 1) two or more vascular conditions; and 2) depression as determined by a normative elevation on the Depression/Dejection subscale of the Profile of Mood States or a diagnosis of Major Depressive Disorder per the Composite International Diagnostic Interview. Everyday functioning was measured by both self- and clinician-rated activities of daily living. A logistic regression model showed that HIV was associated with a three-fold increased risk of vascular depression, independent of potential confounding factors. A second logistic regression model within the PLWH sample showed that PLWH with vascular depression had significantly greater odds of dependence in everyday functioning as compared to PLWH with either vascular disease or depression alone. The elevated frequency of vascular depression in PLWH is consistent with the vascular depression hypothesis from the late-life depression literature. The high rate of functional dependence among PLWH with vascular depression highlights the clinical importance of prospective work on this syndrome in the context of HIV disease.

Abstract
HIV-associated neurocognitive disorders (HAND) affect ~40% of virally suppressed people with HIV (PWH), however, the precise viral dependent and independent changes to the brain are unclear. Here we characterized the CNS reservoir and immune environment of SIV-infected (SIV+) rhesus macaques during acute (n = 4), chronic (n = 12) or ART-suppressed SIV infection (n = 11). Multiplex immunofluorescence for markers of SIV infection (vRNA/vDNA) and immune activation was performed on frontal cortex and matched colon tissue. SIV+ animals contained detectable viral DNA+ cells that were not reduced in the frontal cortex or the gut by ART, supporting the presence of a stable viral reservoir in these compartments. SIV+ animals had impaired blood brain barrier (BBB) integrity and heightened levels of astrocytes or myeloid cells expressing antiviral, anti-inflammatory or oxidative stress markers which were not abrogated by ART. Neuroinflammation and BBB dysfunction correlated with measures of viremia and immune activation in the gut. Furthermore, SIV-uninfected animals with experimentally induced gut damage and colitis showed a similar immune activation profile in the frontal cortex to those of SIV-infected animals, supporting the role of chronic gut damage as an independent source of neuroinflammation. Together, these findings implicate gut-associated immune activation/damage as a significant contributor to neuroinflammation in ART-suppressed HIV/SIV infection which may drive HAND pathogenesis.

Abstract
Background HIV enters the brain soon after seroconversion and causes HIV-associated neurocognitive disorder (HAND). However, the pathogenesis of this insidious impairment at an early stage remains unclear. Objectives To explore functional integration and segregation changes at the early stages of HAND, voxel-level indices of regional homogeneity (ReHo), the amplitude of low-frequency fluctuations (ALFF), and voxel-mirrored homotopic connectivity (VMHC) under two different frequency bands (slow-5: 0.01-0.027 Hz; slow-4: 0.027-0.073 Hz) were analyzed. Methods Ninety-eight people living with HIV (PLWH) and 44 seronegative controls underwent resting-state functional magnetic resonance imaging. Furthermore, all PLWHs underwent neuropsychological and daily functioning tests. The main effect of the group and the interaction between the group and frequency band were investigated. Finally, the relationship between the altered indices and the cognitive domains was explored. Results A significant group-by-frequency interaction was demonstrated in the right thalamus for ReHo; for VMHC, the interaction was observed in the bilateral precuneus and paracentral gyrus. The post hoc Bonferroni test indicated that the alteration of ReHo and VMHC could only be detected in slow-5. PLWH showed significantly reduced ALFF in both the frequency bands in the right occipital gyrus and right calcarine. Moreover, some altered functional integration and segregation indices are related to impaired cognitive function. Conclusion People living with HIV displayed aberrant functional integration and segregation at the early stages of HAND, which is linked to cognitive function. The frequency band of slow-5 might be more sensitive for detecting insidious damage at an early stage.

Abstract
Half of people with human immunodeficiency virus (HIV) have HIV-associated neurocognitive disorder (HAND). Fortunately, cognitive training programs can improve function across cognitive domains, which may translate to everyday functioning. The Training on Purpose (TOPS) Study was designed to reverse HAND by targeting cognitive training to specific cognitive impairments that contributed to the diagnosis. A secondary aim of TOPS was to determine whether such cognitive training improved subjective and objective everyday functioning. In this two-group pre-post experimental design study, 109 adults with HAND were randomized to either: (1) a no-contact control group (no training) or (2) the Individualized-Targeted Cognitive Training group. Each participant received approximately 10 hours of cognitive training in two selected cognitive domains based on her/his individual baseline cognitive performance. Thus, 20 hours of individualized training on these two cognitive domains occurred over a course of 12 weeks in 1-2 hour sessions. Specific to the secondary aim of TOPS, measures of everyday functioning were administered before and after cognitive training to examine transfer effects. The analyses revealed that in general, speed of processing training produced benefits in everyday functioning as measured by the medication adherence visual analogue scale and the Timed Instrumental Activities of Daily Living test. Inconsistent findings were found for the other seven cognitive training protocols in either improving everyday functioning or reducing perceived everyday functioning; however, there may be other contributing factors that obscured such effects needing further research. This study demonstrated that some training protocols vary in efficacy in altering both objective and subjective everyday functioning ability.

Abstract
OBJECTIVE To examine predictors of informant-reported everyday functioning in mild cognitive impairment (MCI) and relations between everyday function and conversion to dementia. METHODS Informants of participants (n = 2614) with mild cognitive impairment (MCI) were administered the Functional Activities Questionnaire (FAQ). Changes in dimensions of functional ability as determined by an exploratory factor analysis (EFA) were examined over 3 years and participant predictors of change were examined using multilevel modeling (MLM). RESULTS The FAQ consisted of 3 factors, multistep, finance, and memory/orientation daily tasks. Impairment in memory/orientation tasks was significantly higher than impairment in multistep tasks. Worse functioning was associated with greater depression, worse memory, worse speed/EF, higher years of education and identifying as White. There was variability in some of these associations with different FAQ factors. Impairments in financial and memory/orientation daily tasks predicted follow-up conversion to dementia. CONCLUSIONS Depression, speed/EF, and memory are consistently associated with domains of everyday functioning. Race, education, and age may be more variability associated with everyday functioning. Specific attention should be paid to subtle declines in the financial and memory/orientation domains as they may uniquely predict future dementia development. Depression may be a modifiable risk factor associated with functional impairment over time.

Abstract
Mild to moderate forms of neurocognitive impairment persist among people living with HIV (PLWH), despite being virally suppressed on antiretroviral therapy. PLWH are disproportionally impacted by physiological and psychosocial comorbidities compared to those without HIV. As adults live longer with HIV, the neurocognitive burden of physiological and psychosocial stressors can impair everyday functioning and may contribute to the development of neurodegenerative diseases such as Alzheimer's disease. This article outlines neurocognitive consequences of everyday stressors in PLWH. While some lifestyle factors can exacerbate inflammatory processes and promote negative neurocognitive health, novel interventions including the use of cannabinoids may be neuroprotective for aging PLWH who are at risk for elevated levels of inflammation from comorbidities. Studies of integrated neurocognitive rehabilitation strategies targeting lifestyle factors are promising for improving neurocognitive health, and may over time, reduce the risk of Alzheimer's disease in PLWH.

Abstract
OBJECTIVE The COVID-19 pandemic necessitated use of remote assessments by clinical neuropsychologists. Telehealth was particularly important for vulnerable groups, including persons living with HIV (PLWH); however, limited internet access can be a serious barrier to care. This study examined the preliminary validity of a telephone-based neuropsychological assessment in a clinical sample of PLWH. METHOD A consecutive series of 59 PLWH were assessed via telephone at an HIV clinic in the southern U.S. between April 2020 and July 2022. The battery included auditory-verbal neuropsychological tests of memory, attention, and executive functions, and questionnaires assessing self-reported mood and activities of daily living (ADL). RESULTS Study measures demonstrated acceptable internal consistency. PLWH demonstrated worse neuropsychological performance compared with expectations derived from the normal curve and an HIV-seronegative adult sample (N = 44). PLWH assessed via telephone demonstrated similar impairment rates to that of a consecutive series of PLWH (N = 41) assessed in-person immediately prior to the pandemic. Higher telephone-based global neuropsychological scores were related to younger age, more education, better fund of knowledge, White race/ethnicity, fewer medical conditions, and fewer depression symptoms. Global neuropsychological impairment was strongly and independently associated with greater dependence in ADL domains, particularly for instrumental activities. CONCLUSIONS Although telephone-based approaches to neuropsychological assessment are not ideal, these data provide support for the feasibility, internal consistency, and preliminary validity of this method in a consecutive clinical series of PLWH. The direct comparability of telephone-based and in-person neuropsychological assessments remains to be determined by prospective, counterbalanced study designs examining both PLWH and seronegative individuals.

Abstract
Background Cognitive impairment (CI) in people living with HIV (PLWH) is an important health concern in the context of an ageing HIV population. Impacting 14–28% of PLWH, CI is associated with lower health-related quality of life (HRQoL), however, evaluation of the illness-specific factors comprising HRQoL in PLWH with CI have not been assessed. Objective We sought to contribute evidence toward an understanding of HRQoL and identify domains of HRQoL in PLWH with CI. Methods Qualitative interviews with 25 PLWH with objective CI related to HIV disease were conducted with participants attending HIV clinics in the UK. Clinically significant CI was defined based on The European AIDS Clinical Society guidelines, requiring: (i) subjective reporting of cognitive symptoms; (ii) symptoms to be related to HIV (e.g. potentially confounding non-HIV related conditions have been excluded or are being optimally managed) and; (iii) formal neuropsychological assessment confirming CI. Median age was 56 years (range 35–80); 18 participants were men (72%); 11 (44%) were white British and 8 (32%) were Black African; 14 (56%) were men that have sex with men and 10 (40%) were heterosexual; median number of years living with HIV was 17 (range 1–34); and all participants were on combination antiretroviral therapy. Analyses employed techniques from grounded theory, underpinned by an inductive, collaborative team-based approach. Results Findings revealed seven interrelated domains comprising HRQoL experiences were identified: Physical function, Cognition, Social connectedness, Physical and mental health, Stigma, Self-concept, and Control and acceptance, and each was defined by specific descriptive components. Conclusion This study provides valuable insights on the factors that drive HRQoL in PLWH with CI and contribute to a body of evidence which provides targets for the development of targeted interventions to maintain or improve quality of life.

Abstract
ABSTRACT HIV-associated neurocognitive disorder (HAND) is experienced by 30% to 50% of people living with HIV (PLWH), potentially affecting their quality of life (QoL). In the Training on Purpose Study, we investigated whether targeted cognitive training can improve QoL in PLWH with HAND. Using a two-group experimental design, we randomized 109 adults with HAND to either (a) the Individualized-Targeted Cognitive Training group or (b) a no-contact control group. Those in the training group were assigned 10 hr of cognitive training per two selected cognitive domains (20 hr total) for which impairment was observed. Overall, two patterns emerged. First, significant improvements in measures of everyday cognitive complaints, depression, and mental health were consistently observed after the completion of many cognitive training protocols. Second, immediate and delayed spatial learning and memory training resulted in more significant indicators of QoL improvements compared with the other cognitive domain trainings. The findings suggest that some types of cognitive training may have advantages over others in improving aspects of QoL.

Impact of HIV-associated cognitive impairment on functional independence, frailty and quality of life in the modern era: a meta-analysis. Sci Rep 2022; 12:6470. [PMID: 35440802 PMCID: PMC9019017 DOI: 10.1038/s41598-022-10474-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2021] [Accepted: 03/31/2022] [Indexed: 11/24/2022] Open
Abstract
HIV-associated neurocognitive disorder (HAND) is an important sequela of HIV infection. Combined antiretroviral therapy (cART) has improved the health outcomes of many people living with HIV but has given rise to a less severe but limiting form of HAND. The study aimed to evaluate the impact of HAND on medication adherence, activities of daily living (ADL), quality of life and frailty. This systematic review adheres to the guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We searched MEDLINE, PubMed, CINAHL, Academic Search Complete, and PsycINFO online databases. Studies were included if they examined the relationship between HAND and medication adherence, ADL, quality of life and frailty, and were conducted between 1997 and 2021. We used a random-effects meta-analysis model to assess the impact of HAND on outcome variables. Forty papers, totaling 11,540 participants, were included in the narrative and quantitative syntheses. Cognitive impairment was associated with poorer medication adherence (r = 0.601, CI 0.338 to 0.776, p = 0.001, I2 = 94.66). Cognitive impairment did not influence ADL (r = 0.167, CI-0.215 to 0.505, p = 0.393) and quality of life (r = 0.244, CI 0.117 to 0.548, p = 0.182). In the cART era, HAND appears to be associated with adherence to medication, which may influence future health outcomes. In PLWHIV who are adherent to cART, cognitive impairment does not appear to interfere with ADL and quality of life.

Neurocognitive performance differences between black and white individuals with HIV disease are mediated by health literacy. Clin Neuropsychol 2022; 36:414-430.

Abstract
Objective:Health disparities are evident for Black Americans with HIV disease, who are disproportionally affected by the epidemic in the United States. The current study investigated whether the higher rates of neurocognitive impairment in Black Americans with HIV disease may be at least partly attributable to health literacy, which is a potentially modifiable factor. Method: Participants were 61 White and 25 Black participants (ages 27-70) with HIV disease who were enrolled in studies at an urban academic center in Southern California. Neurocognitive function was assessed by an age-adjusted global score from the Cogstate battery. Health literacy was measured by a composite score derived from the Rapid Estimate of Adult Literacy in Medicine, Newest Vital Sign, and 3-Brief. Results: Bootstrap confidence interval mediation analyses showed that health literacy was a significant mediator of the relationship between race and neurocognition; that is, there were no direct ethnoracial differences in neurocognition after accounting for health literacy. A follow-up model to confirm the directionality of this association demonstrated that neurocognition was not a significant mediator of the relationship between race and health literacy. Conclusions: Low health literacy may contribute to the higher rates of neurocognitive impairment for Black Americans with HIV disease. Future studies might examine the possible mechanism of this mediating relationship (e.g., access to health information, health behaviors, socioeconomics) and determine whether culturally tailored interventions that improve health literacy also confer broader brain health benefits for Black Americans with HIV disease.

Abstract
Older adults commonly experience difficulties efficiently searching the Internet, which can adversely affect daily functioning. This study specifically examined the neuropsychological aspects of online transit planning in 50 younger (M = 22 years) and 40 older (M = 64 years) community-dwelling adults. All participants completed a neuropsychological battery, questionnaires, and measures of Internet use and skills. Participants used a live transit planning website to complete three inter-related tasks (e.g., map a route from an airport to a specific hotel at a particular time). On a fourth Internet transit task, participants were randomized into either a support condition in which they received brief goal management training or into a control condition. Results showed that older adults were both slower and less accurate than their younger counterparts in completing the first three Internet transit tasks. Within the older adults, Internet transit accuracy showed a medium association with verbal memory, executive functions, and auditory attention, but not visuomotor speed, which was the only domain associated with Internet transit task speed in both groups. The goal management training was beneficial for plan development in younger, but not older adults. The planning supports did not impact actual Internet transit task performance in either group. Findings indicate that older adults experience difficulties quickly and accurately using a transit website to plan transportation routes, which is associated with poorer higher-order neurocognitive functions (e.g., memory). Future work might examine the benefits of established memory strategies (e.g., spaced retrieval practice) for online transit planning.

HIV Transgenic Rats Demonstrate Superior Task Acquisition and Intact Reversal Learning in the Within-Session Probabilistic Reversal Learning Task. COGNITIVE, AFFECTIVE & BEHAVIORAL NEUROSCIENCE 2021; 21:1207-1221.

Abstract
The HIV transgenic (HIVtg) rat is a commonly used animal model of chronic HIV infection that exhibits a wide range of cognitive deficits. To date, relatively little work has been conducted on these rats' capacity for reversal learning, an assay of executive function and cognitive flexibility used in humans. The present study sought to determine the impact of HIV genotype on probabilistic reversal learning, effortful motivation, and spontaneous locomotion/exploration in rats. Male (n = 8) and female (n = 8) HIVtg rats and wildtype (WT) controls were utilized. Cognitive flexibility was assessed via the Probabilistic Reversal Learning Task (PRLT), which reinforced responses to two stimuli on differential probabilistic schedules that periodically reversed. Effortful motivation and locomotor/exploratory behavior were assessed via the Progressive Ratio Breakpoint Task (PRBT) and the Behavioral Pattern Monitor (BPM), respectively. Regardless of sex, HIVtg rats required fewer trials to ascertain initial PRLT reward schedules than WT rats, and completed the same number of reversals. Secondary behaviors suggested that HIVtg PRLT performance was facilitated by a speed-accuracy tradeoff strategy. No main or interactive effects of genotype were observed in the PRBT or BPM. Relative to WT controls, HIVtg rats exhibited superior probabilistic reinforcement learning. Reversal learning was unaffected by HIV genotype, as was effortful motivation and exploratory behavior. These findings contrast with previous characterizations of the HIVtg rat, thus indicating a nuanced cognitive profile that is dependent upon such task specifications as within- versus between-session assessment and probabilistic versus deterministic reward schedules.

Abstract
PURPOSE OF REVIEW While traditional neuropsychological tests are the gold standard in screening for HIV-related cognitive impairment, computerized neuropsychological assessment devices (CNADs) offer an alternative to these time- and resource-intensive batteries and may prove to be particularly useful for remote assessments or longitudinal monitoring. This review seeks to describe the benefits, limitations, and validity of CNADs in the evaluation of HIV-associated neurocognitive disorder (HAND). RECENT FINDINGS We identified eight CNADs that have undergone validity testing for cognitive impairment in the setting of HIV. Included among these are batteries that have been modeled after the traditional neuropsychological exam, as well as others that implement new technologies, such as simulated reality and daily ecological assessments in their testing. Currently, these digital batteries do not yet have the ability to supplant gold standard neuropsychological tests in screening for HAND. However, many have the potential to become effective clinical screening tools.

Abstract
Apathy is common in HIV, separable from depression, and has been associated with non-adherence to antiretroviral therapy (ART). We examined the associations between apathy and critical psychological determinants of ART adherence, as per the information-motivation-behavioral model, in 85 persons living with HIV. Apathy was measured using a composite of the apathy subscale of the Frontal Systems Behavioral Scale and the vigor-activation scale of the Profile of Mood States. Independent of major depressive disorder, apathy was related at small-to-medium effect sizes with motivation to adhere and self-efficacy for health-related decision-making and medication management, but not with HIV knowledge or medication management skills. These findings suggest that apathy plays a unique role in several critical health adherence determinants and support the importance of assessment and management of apathy to maximize health outcomes among individuals with HIV disease.

Abstract
Quality of life (QoL) is recognized as an essential end point in the disease management of chronic conditions such as HIV with calls to include good QoL as a ‘fourth 90’ in the 90-90-90 testing and treatment targets introduced by World Health Organization in 2016. Cognitive impairments impact a broad spectrum of experiences and are a common issue effecting people living with HIV (PLWH). Despite this, few studies have examined QoL in PLWH who also have a cognitive disorder. This study aimed to synthesize and describe what is known about QoL in those living with HIV-associated neurocognitive disorders (HAND). A scoping review of peer-reviewed literature was conducted to identify how QoL has been investigated and measured in PLWH with HAND, and how PLWH with HAND report and describe their QoL. We searched PsychInfo, Medline, Scopus, and Web of Science along with hand-searching reference lists from relevant studies found. Included studies were those published in English after 1st January 2003 which included PLWH with cognitive impairment not due to other pre-existing conditions. Fifteen articles met criteria for inclusion. Two studies measured QoL as a primary aim, with others including QoL assessment as part of a broader battery of outcomes. The MOS-HIV and SF-36 were the most commonly used measures of overall QoL, with findings generally suggestive of poorer overall QoL in PLWH with HAND, compared to PLWH without cognitive impairment. Studies which examined dimensions of QoL focused exclusively on functionality, level of independence, and psychological QoL domains. There is a considerable dearth of research examining QoL in PLWH with HAND. The initiatives which advocate for healthy aging and improved QoL in PLWH must be extended to include and understand the experiences those also living with cognitive impairment. Research is needed to understand the broad experiential impacts of living with these two complex, chronic conditions, to ensure interventions are meaningful to patients and potential benefits are not missed.

Abstract
BACKGROUND clinically relevant methods to identify individuals at risk for impaired daily living abilities secondary to neurocognitive impairment (ADLs) remain elusive. This is especially true for complex clinical conditions such as HIV-Associated Neurocognitive Disorders (HAND). The aim of this study was to identify novel and modifiable factors that have potential to improve diagnostic accuracy of ADL risk, with the long-term goal of guiding future interventions to minimize ADL disruption. METHODS study participants included 79 people with HIV (PWH; mean age = 63; range = 55-80) enrolled in neuroHIV studies at University California San Francisco (UCSF) between 2016 and 2019. All participants were virally suppressed and exhibited objective evidence of neurocognitive impairment. ADL status was defined as either normative (n = 39) or at risk (n = 40) based on a task-based protocol. Gradient boosted multivariate regression (GBM) was employed to identify the combination of variables that differentiated ADL subgroup classification. Predictor variables included demographic factors, HIV disease severity indices, brain white matter integrity quantified using diffusion tensor imaging, cognitive test performance, and health co-morbidities. Model performance was examined using average Area Under the Curve (AUC) with repeated five-fold cross validation. FINDINGS the univariate GBM yielded an average AUC of 83% using Wide Range Achievement test 4 (WRAT-4) reading score, self-reported thought confusion and difficulty reading, radial diffusivity (RD) in the left external capsule, fractional anisotropy (FA) in the left cingulate gyrus, and Stroop performance. The model allowing for two-way interactions modestly improved classification performance (AUC of 88%) and revealed synergies between race, reading ability, cognitive performance, and neuroimaging metrics in the genu and uncinate fasciculus. Conversion of Neuropsychological Assessment Battery Daily Living Module (NAB-DLM) performance from raw scores into T scores amplified differences between White and non-White study participants. INTERPRETATION demographic and sociocultural factors are critical determinants of ADL risk status among older PWH who meet diagnostic criteria for neurocognitive impairment. Task-based ADL assessment that relies heavily on reading proficiency may artificially inflate the frequency/severity of ADL impairment among diverse clinical populations. Culturally relevant measures of ADL status are needed for individuals with acquired neurocognitive disorders, including HAND.

Abstract
Driving ability can be diminished amongst people with HIV with associated neurocognitive impairment (NCI). We explore the relationship between HIV status, NCI and driving ability in professional truck drivers. Forty male professional drivers (20 HIV-positive; mean age = 39.20 ± 7.05) completed a neuropsychological test battery, two driving simulator tasks that assessed driving ability, and a driving history and habits questionnaire. A higher proportion of HIV-positive drivers exhibited impaired overall cognitive performance (p ≤ 0.001). Overall, drivers with NCI (defined as z ≤ 1.00) were more likely than those without NCI to crash (p = 0.002). There were no significant between-group (HIV-positive versus HIV-negative) differences with regard to self-reported on-road driving events. Professional drivers with NCI, as measured on a driving simulator, are at increased risk of making driving errors under high-risk conditions compared to their neurocognitively normal counterparts. These data should inform driver health management with regard to annual medical screening and surveillance.

Abstract
OBJECTIVE The increased use of online pharmacy services in the midst of the COVID-19 pandemic provides an important backdrop against which to examine the role of neurocognitive functions in health-related Internet navigation skills among persons with chronic medical conditions, such as HIV disease. Prospective memory (PM) is reliably impaired in HIV disease and is related to laboratory-based measures of medication management capacity in other populations. This study examined whether PM shows veridicality in relationship to online pharmacy navigation skills in persons with HIV disease. METHOD Participants included 98 persons with HIV disease age 50 and older who completed the Cambridge Prospective Memory Test (CAMPROMPT) and the Medication-Management Test-Revised (MMT-R) as part of a neuropsychological study. Participants also completed the Test of Online Pharmacy Skills (TOPS), which required them to navigate a simulated, experimenter-controlled online pharmacy to perform several naturalistic tasks (e.g., refill an existing prescription). RESULTS Lower PM had medium associations with poorer MMT-R and TOPS accuracy scores that were not better explained by other neurocognitive functions. The association between PM and TOPS accuracy was driven by errors of omission and did not vary meaningfully based on whether the intention was cued by time or an event. CONCLUSIONS These data suggest that PM cue detection processes show veridicality with online pharmacy navigation skills. Future studies might examine the benefits of PM-based strategies (e.g., salient prompts) in supporting online health navigation skills in populations that experience clinically impactful PM failures.

Abstract
Approximately 59% of adults living with HIV experience HIV-associated neurocognitive disorder, a collection of symptoms and cognitive deficits in various cognitive domains. As the HIV population ages, the prevalence and severity of such cognitive deficits are expected to grow. Understanding how these cognitive deficits manifest is important for nurses and health care providers. This article provides an overview of cognitive reserve and evidence of how it is compromised by HIV, aging, and individual characteristics. Within this context of cognitive reserve, the role of neuroinflammation, neurotoxicity, substance use, comorbidities, depression and anxiety, social isolation, and sedentary lifestyle is reviewed. From this, strategies used to address cognitive deficits are provided, including topics such as psychostimulants, cognitive training, multimodal lifestyle interventions, and compensation strategies. Scenarios of successful and unsuccessful cognitive aging are presented to provide a lifespan perspective of cognitive reserve. Implications for clinical practice and research are provided, as it relates to aging.

It typically affects memory, learning, working memory, fine motor skills, speed of information processing, verbal fluency and executive functioning cognitive domains. NCI can affect adherence to antiretroviral therapy (ART), employability, driving ability and activities of daily living. NCI is not routinely screened for in Zimbabwe, and the burden is not known in this setting. The objectives of this study were: 1) To determine NCI prevalence using a comprehensive neuropsychological battery at two primary health care clinics in Harare; 2) To assess the pattern of cognitive impairment across cognitive domains using a gold standard neuropsychological (NP) battery in HIV-positive patients compared to HIV-negative controls. Methods Inclusion criteria: 18 years or older; minimum 7 years education; no neurological or psychiatric disorders. HIV-positive participants were on ART for ≥3 months; HIV-negative participants had a confirmed HIV negative status in the past month. A comprehensive NP battery, functional assessments, demographic and medical history questionnaires were administered. The NP battery consisted of tests assessing memory, learning, working memory, fine motor skills, speed of information processing, verbal fluency and executive functioning. Results Two-hundred-and-thirty-one participants were recruited. Of those, 155 were HIV-positive (Female = 70%, Age M = 37.8; SD 11.2) and 76 HIV-negative (Female = 63%, Age M = 31.2; SD 9.9). HIV-positive participants were on ART for an average of 6 years. NCI was present in 49.7% HIV positive participants. Compared to HIV-negative participants, the HIV-positive group had significantly poorer scores in 5 out of 7 cognitive domains. A good level of education is negatively correlated with NCI. Conclusions NCI prevalence in HIV-positive population Zimbabwe is consistent with global estimates. NCI persists in adults who are on ART. Routine assessment of NCI in adults attending primary care clinics using this adapted battery is therefore important so that they are identified early and are provided the necessary interventions.

Abstract
Human immunodeficiency virus (HIV)-associated neurocognitive disorders (HAND) affect approximately half of people living with HIV despite viral suppression with antiretroviral therapies and represent a major cause of morbidity. HAND affects activities of daily living including driving, using the Internet and, importantly, maintaining drug adherence. Whilst viral suppression with antiretroviral therapies (ART) has reduced the incidence of severe dementia, mild neurocognitive impairments continue to remain prevalent. The neuropathogenesis of HAND in the context of viral suppression remains ill-defined, but underlying neuroinflammation is likely central and driven by a combination of chronic intermittent low-level replication of whole virus or viral components, latent HIV infection, peripheral inflammation possibly from a disturbed gut microbiome or chronic cellular dysfunction in the central nervous system. HAND is optimally diagnosed by clinical assessment with imaging and neuropsychological testing, which can be difficult to perform in resource-limited settings. Thus, the identification of biomarkers of disease is a key focus of the field. In this chapter, recent advances in the pathogenesis of HAND and biomarkers that may aid its diagnosis and treatment will be discussed.

Abstract
The Frascati criteria for HIV-associated neurocognitive disorders (HAND; Antinori et al. 2007) outlines a classification scheme for functional decline that-despite being over a decade old-has not heretofore been examined systematically. Participants included 307 HIV+ and 183 HIV- participants who completed self-report, clinician-rated, and performance-based measures of functional status, along with neurocognitive, psychiatric, and medical/laboratory assessments. Using the Frascati criteria, we classified participants with (1) no functional declines, (2) mild functional declines, or (3) major functional declines. A multivariable logistic regression showed that HIV serostatus was associated with higher rates of major (33.2 vs. 13.7%) but not mild (38.8 vs. 31.7%) Frascati-defined functional decline. Within the HIV+ group, individuals with global neurocognitive impairment and affective disorders were at highest risk of Frascati-defined functional decline. Findings provide some empirical support for the sensitivity and validity of the Frascati criteria for functional declines in the context of HAND. Future work is needed to determine the reliability, stability, cross-cultural validity, and downstream health-related consequences of the Frascati-defined functional classifications.

Abstract
Abstract
Objective
The Neuropsychological Assessment Battery Bill Payment subtest has shown strong diagnostic accuracy in dementia due to Alzheimer’s disease (AD) versus non-AD. Its relationship to mild cognitive impairment (MCI) or all-cause dementia has not been fully examined nor has its ecological validity as a proxy of financial independence.
Method
We describe 270 women (63%) and men (age = 72 ± 8.39) who completed Bill Payment during outpatient neuropsychological evaluation. Seventy-one were cognitively normal (CN), 160 had MCI, and 39 had Dementia. Two hundred fourteen were independent in money management, 31 were assisted (had oversight/some help), and 25 were dependent (relied on others). Receiver operating characteristic (ROC) curves tested Bill Payment’s utility as a dementia screen. Kruskal–Wallis tests examined whether Bill Payment differed by levels of financial independence.
Results
At a cutoff of 17, Bill Payment had strong sensitivity (0.87) and specificity (0.80) for dementia versus CN cases. A cutoff of 15 distinguished dementia from MCI (Sn = 0.64, Sp = 0.85), whereas a cutoff of 16 distinguished dementia from functionally unimpaired cases (MCI + CN) with greater sensitivity and similar specificity (Sn = 0.74, Sp = 0.81). Sensitivity attenuated in MCI versus CN cases (Sn = 0.46, Sp = 0.83). Those who were independent in money management had higher scores than assisted and dependent cases (p ≤ 0.046). Assisted and dependent cases were no different (p > 0.05).
Conclusions
Bill Payment is a valid screen of all-cause dementia. Lower Bill Payment scores may mark subtle functional decline beyond cognitive impairment alone. Specifically, results provide preliminary evidence of Bill Payment’s ecological validity as a measure related to financial independence. It may prove useful when impaired financial abilities are suspected but unreported.

Abstract
Objective: People living with HIV (PLWH) are at risk for HIV-Associated Neurocognitive Disorders (HAND)/Neurocognitive Impairment (NCI). HIV prevalence in Sub-Saharan Africa (SSA) is high, but neuropsychological screening and testing for NCI among HIV-infected individuals is not done frequently. This systematic review aims to establish how NCI among HIV-infected individuals is being assessed in SSA, if and how the tests are adapted, if norms exist and identify personnel who administer them.Method: We searched PubMed, Medline, EBSCO, PsycINFO, and Web of Science. Two reviewers screened the articles for inclusion and risk of bias. We included studies from SSA with a comprehensive neuropsychological assessment battery.Results: We retrieved 212 articles and 23 articles met inclusion criteria. The most commonly used tests were the Color Trails Test 1, Color Trails Test 2, and the WAIS III Digit Symbol Test. Some tests were translated into French (Cameroon), Luganda (Uganda), Chichewa (Malawi), isiXhosa (South Africa), and Afrikaans (South Africa). Some verbal learning tests were adapted to reflect culturally appropriate language. Test administrators were either non-specialized personnel supervised by clinical neuropsychologists or clinical psychologists.Conclusion: Overall, the tests used are similar to the tests being used globally to assess NCI among HIV-infected individuals and there is a general consistency across countries. However, there is generally a lack of norms for the tests and the process of adaptation is not always well described. Future research should establish whether these tests measure neuropsychological constructs as successfully as they do in western populations where the tests were developed.

Abstract
HIV-associated neurocognitive impairment is an independent predictor of low general health literacy, which can be associated with poor disease outcomes (e.g., viremia). Given the increasing frequency with which health behaviors occur in an online environment (e.g., health information seeking, provider interactions), there is a specific need to understand the predictors of electronic health (eHealth) literacy of persons living with HIV disease. In this study, 90 HIV+ persons completed the eHealth Literacy Scale (eHEALS), which measures one's awareness, skills and evaluation of online health resources. Participants also completed a comprehensive battery of clinical neurocognitive tests and well-validated performance-based measures of general health literacy capacity (e.g., knowledge, numeracy). Results showed that, independent of education, lower neurocognitive function was moderately related to lower eHEALS scores, particularly in the domains of learning and motor skills. Of particular note, general health literacy capacity emerged as a significant mediator of the relationship between neurocognition and eHealth literacy. Thus, the adverse effects of neurocognition on health literacy capacity carries a downstream adverse influence on HIV+ persons' awareness, skills, and evaluation of health-related resources in the online environment.

Abstract
OBJECTIVE Over the last 20 years, the Internet has become a fundamental means by which many people with neurocognitive disorders manage their activities of daily living (e.g. shopping) and engage in health behaviors (e.g. appointment scheduling). The aim of this review is to summarize the emerging literature on the neuropsychology of performance-based tasks of Internet navigation skills (INS) as measures of everyday functioning. METHOD We performed a structured, qualitative review of the extant literature on INS using PRISMA guidelines. RESULTS Seventeen peer-reviewed studies met inclusion criteria and their results suggest that performance-based tests of INS: (1) discriminate healthy adults from some neuropsychological populations [e.g. human immunodeficiency virus (HIV), multiple sclerosis (MS), traumatic brain injury (TBI)]; (2) are associated with performance-based tests of everyday functioning capacity, domain-specific declines in manifest everyday functioning, and self-reported Internet behavior, but not global manifest functional status; (3) correlate with standard clinical neuropsychological tests, particularly executive functions and episodic memory; (4) may relate to demographic factors, most notably age; and (5) have largely unknown psychometric properties (e.g. reliability). CONCLUSION This review provided early support for the construct validity of performance-based tasks of INS as modern measures of everyday functioning in neuropsychological populations. Future work is needed to refine these tasks, establish their psychometrics, and evaluate their construct validity in diverse populations, as well as to develop effective remediation and compensatory strategies to improve Internet functionality among persons with neurocognitive disorders.

Abstract
Combination antiretroviral therapy has reduced the rates of severe HIV-associated neurocognitive disorders (HAND), but the prevalence of milder forms of HAND that can affect everyday functioning remains high. As HIV-infected adults approach near-normal life expectancies, they may become increasingly susceptible to declines in everyday functioning secondary to a variety of physical and mental factors, including HAND. Although impairments in everyday functioning are a hallmark of HAND diagnoses and can adversely influence quality of life, there are no gold standard measures of this fundamentally important and complex construct. This chapter provides a brief review of the various self-report, clinician-rated, and performance-based methods by which everyday functioning is measured in the setting of HIV disease, including global activities of daily living and specific domains of medication adherence, financial management, automobile driving, and vocational functioning.

Abstract
The present review on HIV-associated neurocognitive disorders (HAND) provides a worldwide overview of studies that have investigated the rate and neuropsychological (NP) profile of HAND research since the inception of the 2007 HAND diagnostic nomenclature. In the first part, the review highlights some of the current controversies around HAND prevalence rates. In the second part, the review critically assesses some solutions to move the field forward. In the third part, we present the cross-sectional NP profile in non-Western HIV+ cohorts and in relation to Western cohorts' findings. The adopted global perspective highlights the successful expansion of NP studies in HIV infection to culturally diverse low- to medium-income countries with high HIV burden. These studies have produced interestingly similar rates of HAND whether patients were naïve or treated and/or virally suppressed compared to the rich income countries where the NP research in NeuroHIV has originated. The perspective also demonstrates that globally, the group which is the most representative of the HIV epidemic, and thus at risk for HAND are persons with chronic HIV infection and survivors of past immunosuppression, while in relative terms, those who have been treated early with long-term viral suppression represent a minority. In the last part, we present a review of the naturalistic longitudinal NP global studies in HIV+cohorts, discuss the role of longitudinal design in solving issues around the question of asymptomatic neurocognitive impairment, and the question of biomarker discovery. Finally, we conclude by calling for greater methods and data harmonization at a global level. (JINS, 2017, 23, 860-869).

Abstract
Neuropsychological assessment tools are the staple of our field. The development of standardized metrics sensitive to brain-behavior relationships has shaped the neuropsychological questions we can ask, our understanding of discrete brain functions, and has informed the detection and treatment of neurological disorders. We identify key turning points and innovations in neuropsychological assessment over the past 40-50 years that highlight how the tools used in common practice today came to be. Also selected for emphasis are several exciting lines of research and novel approaches that are underway to further probe and characterize brain functions to enhance diagnostic and treatment outcomes. We provide a brief historical review of different clinical neuropsychological assessment approaches (Lurian, Flexible and Fixed Batteries, Boston Process Approach) and critical developments that have influenced their interpretation (normative standards, cultural considerations, longitudinal change, common metric batteries, and translational assessment constructs). Lastly, we discuss growing trends in assessment including technological advances, efforts to integrate neuropsychology across disciplines (e.g., primary care), and changes in neuropsychological assessment infrastructure. Neuropsychological assessment has undergone massive growth in the past several decades. Nonetheless, there remain many unanswered questions and future challenges to better support measurement tools and translate assessment findings into meaningful recommendations and treatments. As technology and our understanding of brain function advance, efforts to support infrastructure for both traditional and novel assessment approaches and integration of complementary brain assessment tools from other disciplines will be integral to inform brain health treatments and promote the growth of our field.
