ObjectiveTo test the hypothesis that repetitive head impacts (RHIs), like those from contact sport play and traumatic brain injury (TBI) have long-term neuropsychiatric and cognitive consequences, we compared middle-age and older adult participants who reported a history of RHI and/or TBI with those without this history on measures of depression and cognition.MethodsThis cross-sectional study included 13,323 individuals (mean age, 61.95; 72.5% female) from the Brain Health Registry who completed online assessments, including the Ohio State University TBI Identification Method, the Geriatric Depression Scale (GDS-15), and the CogState Brief Battery and Lumos Labs NeuroCognitive Performance Tests. Inverse propensity-weighted linear regressions accounting for age, sex, race/ethnicity, and education tested the effects of RHI and TBI compared to a non-RHI/TBI group.ResultsA total of 725 participants reported RHI exposure (mostly contact sport play and abuse) and 7,277 reported TBI (n = 2,604 with loss of consciousness [LOC]). RHI (β, 1.24; 95% CI, 0.36–2.12), TBI without LOC (β, 0.43; 95% CI, 0.31–0.54), and TBI with LOC (β, 0.75; 95% CI, 0.59–0.91) corresponded to higher GDS-15 scores. While TBI with LOC had the most neuropsychological associations, TBI without LOC had a negative effect on CogState Identification (β, 0.004; 95% CI, 0.001–0.01) and CogState One Back Test (β, 0.004; 95% CI, 0.0002–0.01). RHI predicted worse CogState One Back Test scores (β, 0.02; 95% CI, −0.01 to 0.05). There were RHI × TBI interaction effects on several neuropsychological subtests, and participants who had a history of both RHI and TBI with LOC had the greatest depression symptoms and worse cognition.ConclusionsRHI and TBI independently contributed to worse mid- to later-life neuropsychiatric and cognitive functioning.

Background: Athletes who participate in collision sports may experience more repetitive head impacts than other sport types. These repetitive head impacts have been theorized as a potential catalyst for cognitive problems later in life. It is unknown, however, if sport type influences neurocognitive performance. Hypothesis/Purpose: Our purpose was to investigate the association between sport type and baseline neurocognitive scores in a high school athletic population. We hypothesized that athletes participating in collision sports would demonstrate worse scores on baseline neurocognitive tests compared to those in contact or non-contact sports. Methods: We conducted a cross-sectional, observational study using baseline computerized neurocognitive scores of 186,117 high school student-athletes (age: 15.47±2.28 years, height: 168.53±10.77 cm, weight: 63.02±14.83 kg, 45% female) in the state of Massachusetts. The dependent variables were five composite scores (verbal memory, visual memory, visual motor, reaction time, and impulse control) and total symptom score. The independent variables included sport type (collision, contact, non-contact), age, sex, and concussion history. We used univariable one-way ANOVAS to compare composite scores between sport type. We conducted a series of multivariable regression models, controlling for age, sex, and number of previous concussions, to examine the independent association between sport type and composite scores. Results: There was a minimal but statistically significant association between sport type and composite scores, with collision sport athletes performing slightly worse than other athletes on most composite scores. Collision sport athletes had a slightly lower symptom burden. (Tables 1 and 2) Conclusion: While statistically significant, the differences in neurocognitive function and symptom burden between sport type are of questionable clinical significance. In fact, all of them fall within the reliable change index values of each respective score. As participants were in high school at the time of the study, we cannot determine the potential for associations later in life. Tables/Figures: [Table: see text][Table: see text]

Objective: Online banking is becoming increasingly common among older adults, whomay experience difficulties effectively navigating this instrumental technology. Thisstudy examined age effects on a performance-based Internet banking task and itsassociation with neurocognitive ability and functional capacity in older and youngeradults. Method: Thirty-five older adults and 50 younger adults completed anexperimenter-controlled online banking measure in which they independentlyperformed a series of naturalistic financial tasks (e.g., account transfers, bill paying).Participants also completed a standardized battery of neuropsychological tests andmeasures of functional capacity. Results: Older adults were markedly slower and lessaccurate in completing the Internet-based banking task, which was not confounded byother demographic, mood, or computer use factors. Higher scores on measures ofneurocognition and financial functional capacity were both strongly associated withhigher Internet-based banking task accuracy scores and quicker completion times inthe older, but not the younger adults. Conclusions: Findings suggest that older adultsexperience difficultly quickly and accurately navigating online banking platforms, whichmay be partly related to age-related declines in neurocognitive functions and basicfinancial capacity. Future studies might examine whether neurocognitive approaches toremediation and compensation can be used to improve online banking capacity inolder adults.

Human immunodeficiency virus enters the central nervous system (CNS) early after systemic infection, and may cause neural injury and associated neurocognitive impairment through multiple direct and indirect mechanisms. An international conference of multidisciplinary neuroAIDS experts convened in 2005 to propose operationalized research criteria for HIV-related cognitive and everyday functioning impairments. The resulting classification system, known as the Frascati criteria, defined three types of HIV-associated neurocognitive disorder (HAND): asymptomatic neurocognitive impairment, mild neurocognitive disorder, and HIV-associated dementia (HAD). Consideration of comorbid conditions that can influence neurocognitive performance, such as developmental disabilities, non-HIV forms of CNS compromise (neurological and systemic), severe psychiatric conditions, and substance use disorders, is essential to differential diagnosis. Since the introduction of combination antiretroviral therapy (ART), rates of severe HAND (i.e., HAD) have greatly declined, although the milder forms of HAND remain quite prevalent, even in virally suppressed people living with HIV (PLWH). Beyond ART, clinical management of HAND includes behavioral interventions focused on neurocognitive and functional improvements. This chapter covers a range of HAND-related topics, such as the neuropathological mechanisms of HIV-related CNS injury, assessment and diagnostic systems for neurocognitive and everyday functioning impairment in HIV, treatment and protective factors, aging with HIV, HAND in international settings, and ongoing challenges and controversies in the field. Future needs for progress with HAND include advances in early detection of mild cognitive deficits and associated functional impairment in PLWH; biomarkers that may be sensitive to its underlying pathogenesis; and differential diagnosis of HAND versus age-related, non-HIV-associated disorders.
