There is debate as to whether the neurocognitive changes associated with HIV infection represent an acceleration of the typical aging process or more simply reflect a greater accentuated risk for age-related declines. We aimed to determine whether accelerated neurocognitive aging is observable in a sample of older HIV-infected individuals compared to age-matched seronegatives and older-old (i.e., aged ≥ 65) seronegative adults. Participants in a cross-sectional design included 48 HIV-seronegative (O−) and 40 HIV-positive (O+) participants between the ages of 50–65 (mean ages = 55 and 56, respectively) and 40 HIV-seronegative participants aged ≥ 65 (OO−; mean age = 74) who were comparable for other demographics. All participants were administered a brief neurocognitive battery of attention, episodic memory, speeded executive functions, and confrontation naming (i.e., Boston Naming Test). The O+ group performed more poorly than the O− group (i.e., accentuated aging), but not differently from the OO− on digit span and initial recall of a supraspan word list, consistent with an accelerating aging profile. However, the O+ group’s performance was comparable to the O− group on all other neurocognitive tests (ps > .05). These data partially support a model of accelerated neurocognitive aging in HIV-infection, which was observed in the domain of auditory verbal attention, but not in the areas of memory, language, or speeded executive functions. Future studies should examine whether HIV-infected adults over 65 evidence accelerated aging in downstream neurocognitive domains and subsequent everyday functioning outcomes.

There is a rising prevalence of older HIV+ adults who are at risk of deficits in higher-order neurocognitive functions and associated problems in everyday functioning. The current study applied Multiprocess Theory to examine the effects of HIV and aging on measures of laboratory-based, naturalistic, and self-perceived symptoms of prospective memory (PM). Participants included 125 Younger (48 with HIV, age = 32±4.6 years) and 189 Older (112 with HIV, age = 56±4.9 years) adults. Controlling for global neurocognitive functioning, mood, and other demographics, older age and HIV had independent effects on long-delay time-based PM in the laboratory, whereas on a naturalistic PM task older HIV− adults performed better than older HIV+ adults and younger persons. In line with the naturalistic findings, older age, but not HIV, was associated with a relative sparing of self-perceived PM failures in daily life across longer delay self-cued intervals. Findings suggest that, even in relatively younger aging cohorts, the effects of HIV and older age on PM can vary across PM delay intervals by the strategic demands of the retrieval cue type, are expressed differently in the laboratory and in daily life, and are independent of other higher-order neurocognitive functions (e.g., retrospective memory).

HIV-associated neurocognitive disorders (HAND) occur in approximately 50% of HIV-infected individuals, yet available diagnostic criteria yield varying prevalence rates. This study examined the frequency, reliability, and sensitivity to everyday functioning problems of three HAND diagnostic criteria (DSM-5, Frascati, Gisslén). Participants included 361 adults with HIV disease and 199 seronegative adults. Neurocognitive status as defined by each of the three diagnostic systems was determined via a comprehensive neuropsychological battery. Everyday functioning was evaluated through self-report and clinician ratings. Results of logistic regressions revealed an association of HIV serostatus with Frascati-defined neurocognitive impairment (p=.027, OR=1.7[1.1, 2.7]), but not DSM-5 or Gisslén-defined criteria (ps>.05). Frascati and DSM-5 criteria demonstrated agreement on 71% of observations, Frascati and Gisslén showed agreement on 80%, and DSM-5 and Gisslén criteria showed agreement on 46%, though reliability across the three criteria was poor. Only Frascati-defined neurocognitive impairment significantly predicted everyday functioning problems (p=.002, OR=2.3[1.4,3.8]). However, when both neurocognitive and complaint criteria were considered, the DSM-5 guidelines demonstrated significant relationships to everyday functioning, serostatus and also increased reliability overtime compared to neurocognitive criteria alone (all ps < .05). A subset (n = 118) of the HIV+ group was assessed again after 14.0 (2.2) months. DSM-5 criteria evidenced significantly higher rates of incident neurocognitive disorder compared to both Frascati (p = .003) and Gisslén (p = .021) guidelines, while there were fewer remitting neurocognitive disorder diagnoses when Gisslén criteria were applied to the study sample compared to Frascati (p = .04). Future studies should aim to identify gold standard biological markers (e.g., neuropathology) and clinical outcomes associated with specific diagnostic criteria.

HIV-associated PM deficits are common and exert a significant adverse effect on the daily lives and health of infected persons. Much work remains to be done to understand the cognitive architecture of HIV-associated PM deficits and the most efficient means to enhance PM functioning and improve health outcomes in persons living with HIV.

AbstractPurpose -The study is a preliminary attempt to identify cognitive factors (e.g., executive functions and intelligence) promoting resilience in youth in an underprivileged population. Sample consisted of 26 adolescents (seven female, 19 male) between the ages of 13 and 19 years (M ¼ 16.62, SD ¼ 1.53) from an underserved population who live in circumstances of poverty and family dysfunction and who had experienced multiple traumas. Design/methodology/approach -Resilience was measured with the Child and Youth Resilience Measure (CYRM)-28. Intelligence, working memory, and information processing speed were the cognitive factors of interest. Socioeconomic status was the environmental factor in interest. Findings -The protective factors (i.e. individual skills, relationship with caregivers and contextual factors) promoting resilience were correlated with cognitive factors. Further analyses yielded gender differences in these relations. Originality/value -Long-held beliefs that intelligence is positively associated with resilience are brought into question by these findings. The relationship between these concepts seems to differ in accordance with socioeconomic status.
