Abstract
BACKGROUND Self-report of motor and non-motor symptoms is integral to understanding daily challenges of persons with Parkinson's disease (PwPD). Care partners are often asked to serve as informants regarding symptom severity, raising the question of concordance with PwPD self-reports, especially regarding internalized (not outwardly visible) symptoms. OBJECTIVES Concordance between PwPD and informant ratings of motor and non-motor symptoms was evaluated across multiple domains. METHODS In 60 PwPD-informant pairs, we compared ratings on 11 online self-report measures comprising 33 total scores, 2/3 of which represented purely internalized symptoms. For discordant scores, multiple regression analyses were used to examine demographic/clinical predictors. RESULTS Though concordant on 85% of measures, PwPD endorsed more non-motor symptoms, bodily discomfort, stigma, and motor symptoms than informants. For PwPD, younger age, greater disease severity, and female gender predicted discordance. CONCLUSIONS Discordance between PwPD and informants on measures assessing symptoms that cannot be outwardly observed may require targeted education.

Abstract
OBJECTIVE Functional near-infrared spectroscopy (fNIRS) is a non-invasive functional neuroimaging method that indirectly measures cortical activation via task-related changes in oxygenated hemoglobin (HbO). We used fNIRS during a working memory task to assess learning effect over time by assessing brain activity (fNIRS signal) and task performance. We hypothesized that in later blocks of the task, learning (better accuracy) would be correlated to less increase in HbO in prefrontal regions, indicating improved cognitive efficiency. METHOD Eighteen healthy adults [mean age = 24.9 (SD = 4.2); 14 female] engaged in 8 blocks of serial-3 subtraction for 30 seconds each followed by 20 seconds of rest. fNIRS data were collected in 8 cortical regions of interest (ROI) broadly covering the frontal lobe. fNIRS signal in each ROI and task-performance data were compared for the first 4 and last 4 blocks to examine learning. RESULTS fNIRS signal was significantly greater for the first 4 than last 4 blocks (z = -2.1, p < 0.05) in only the right dorsolateral prefrontal cortex ROI. No learning effects appeared for any task-performance variables. CONCLUSIONS These results indicate a dissociation between brain activity and task performance during a working memory task in healthy adults. There was less activity in the right dorsolateral prefrontal cortex during later than earlier trials, indicating an increase in this region's efficiency, without a change in task performance. The results suggest that fNIRS may be sensitive to change in brain activity before it appears clinically, which may be useful in studying people with conditions such as preclinical Alzheimer's disease, and in assessing subtle effects of interventions.

Abstract
Prior teleneuropsychological research has assessed the reliability between in-person and remote administration of cognitive assessments. Few, if any, studies have examined the test-retest reliability of cognitive assessments conducted in sequential clinic-to-home or home-to-home teleneuropsychological evaluations - a critical issue given the state of clinical practice during the COVID-19 pandemic. This study examined this key psychometric question for several cognitive tests administered over repeated videoconferencing visits 4-6 months apart in a sample of healthy English-speaking adults. A total of 44 participants (ages 18-75) completed baseline and follow-up cognitive testing 4-6 months apart. Testing was conducted in a home-to-home setting over HIPAA-compliant videoconferencing meetings on participants' audio-visual enabled laptop or desktop computers. The following measures were repeated at both virtual visits: the Controlled Oral Word Association Test (FAS), Category Fluency (Animals), and Digit Span Forward and Backward from the Wechsler Adult Intelligence Scale, Fourth Edition. Intraclass correlation coefficients (ICC), Pearson correlations, root mean square difference (RMSD), and concordance correlation coefficients (CCC) were calculated as test-retest reliability metrics, and practice effects were assessed using paired-samples t-tests. Some tests exhibited small practice effects, and test-retest reliability was marginal or worse for all measures except FAS, which had adequate reliability (based on ICC and r). Reliability estimates with RMSD suggested that change within +/- 1 SD on these measures may reflect typical test-retest variability. The included cognitive measures exhibited questionable reliability over repeated home-to-home videoconferencing evaluations. Future teleneuropsychology test-retest reliability research is needed with larger, more diverse samples and in clinical populations.

Abstract
STUDY OBJECTIVES Slow wave and spindle coupling supports memory consolidation, and loss of coupling is linked with cognitive decline and neurodegeneration. Coupling is proposed to be a possible biomarker of neurological disease, yet little is known about the different subtypes of coupling that normally occur throughout human development and aging. Here we identify distinct subtypes of spindles within slow wave upstates and describe their relationships with sleep stage across the human lifespan. METHODS Coupling within a cross-sectional cohort of 582 subjects was quantified from stages N2 and N3 sleep across ages 6-88 years old. Results were analyzed across the study population via mixed model regression. Within a subset of subjects, we further utilized coupling to identify discrete subtypes of slow waves by their coupled spindles. RESULTS Two different subtypes of spindles were identified during the upstates of (distinct) slow waves: an "early-fast" spindle, more common in stage N2 sleep, and a "late-fast" spindle, more common in stage N3. We further found stages N2 and N3 sleep contain a mixture of discrete subtypes of slow waves, each identified by their unique coupled-spindle timing and frequency. The relative contribution of coupling subtypes shifts across the human lifespan, and a deeper sleep phenotype prevails with increasing age. CONCLUSIONS Distinct subtypes of slow waves and coupled spindles form the composite of slow wave sleep. Our findings support a model of sleep-dependent synaptic regulation via discrete slow wave/spindle coupling subtypes and advance a conceptual framework for the development of coupling-based biomarkers in age-associated neurological disease.

Abstract
Introduction: Aging is associated with heterogeneous cognitive trajectories. There is considerable interest in identifying risk factors for pathological aging, with recent studies demonstrating a link between surgical procedures and proximal cognitive decline; however, the role of lifetime exposure to surgical procedures and cognitive function has been relatively unexplored. This pilot study aimed to evaluate the association between total lifetime surgical procedures and memory function in older adults. Methods: A cohort of 62 older adults underwent a neuropsychological evaluation and health history assessment. Self-reported lifetime surgical history was categorized as "cardiac" or "non-cardiac." General linear models were fit with demographics as nuisance covariates, and the total number of non-cardiac surgeries as our predictor of interest. Total scores on measures of episodic memory, language, working memory, fluency, and visuospatial function were separate outcome variables. In a secondary analysis, vascular risk factors were included as covariates. Diffusion tensor imaging was obtained for exploratory analyses of selected regions of interest. Results: The mean age of participants was 70, and 0-13 lifetime non-cardiac surgical procedures were reported. Higher numbers of lifetime non-cardiac surgical procedures were associated with worse verbal learning and memory (p = .04). The negative association between lifetime non-cardiac procedures and cognition was specific to memory. Exploratory analyses showed that higher number of lifetime non-cardiac procedures was related to lower FA in the fornix body (p = .02). Conclusions: These results of this pilot study suggest that greater lifetime exposure to surgery may be associated with worse verbal learning and memory in healthy older adults. These findings add to a growing body of literature suggesting that cumulative medical events may be risk factors for negative cognitive outcomes.

Abstract
BACKGROUND Virtual reality applications to assist older adult with cognitive and functional decline are fast growing. However, such technological developments face limitations such as due to limited constructs and ecological validity. This study was aimed at investigating age-related changes in functional abilities and their associated cognitive underpinnings during task performance in virtual and real environments. METHOD Twenty-two younger adults (university students) and 22 older adults (aged 58-74) performed a multiple errands task twice, once in the "Discoveries" section of the National Museum of Scotland and once in the same room as a virtual environment. Accuracy and distance traveled were measured in both groups. Cognitive and daily living abilities were recorded in older adults using standard and novel questionnaires. RESULTS The testing environment had a significant effect on how efficient individuals performed the task. Older and younger adults' performance was alike but older adults relied on more cognitive resources. Older adults struggled in the virtual but not in the real environment. Younger but not older adults could transfer knowledge between environments. CONCLUSION The use of technology to assist frail older adults and those affected by dementia is growing rapidly. For these novel tools to be theoretically valid, they need to incorporate knowledge of the challenges they pose to these vulnerable groups. Here we present evidence of such challenges and their cognitive underpinnings. This theory may be considered by future applications aimed at enhancing functional abilities in these populations.

Abstract
Medical decision-making requires the integration on costs, risks, and benefits of treatment. Clinical side effects and benefits are typically expressed in terms of symptoms and clinical states of diseases. Integrating probabilistic information about different categories is often difficult from both the patient's and the clinician's perspectives. We offer a General Health Policy Model that expresses the benefits and side effects of treatment within a common unit. The model takes into consideration mortality, function (morbidity), and preference for health states. In addition, the model uses probability information to describe the prognosis or likelihood of transition among states over the course of time. The output of the model is a well-year which is defined as the equivalent of a completely well-year of life. The well-year is a comprehensive expression of benefits minus side effects that may be useful for individual patient decision-making.
