Background To determine if accelerometer measured sedentary behavior (SED), light‐intensity physical activity (LPA), and moderate‐to‐vigorous–intensity physical activity (MVPA) in midlife is prospectively associated with cognitive function. Methods and Results Participants were 1970 adults enrolled in the CARDIA (Coronary Artery Risk Development in Young Adults) study who wore an accelerometer in 2005 to 2006 (ages 38–50 years) and had cognitive function assessments completed 5 and/or 10 years later. SED, LPA, and MVPA were measured by an ActiGraph 7164 accelerometer. Cognitive function tests included the Digit Symbol Substitution Test, Rey Auditory Verbal Learning Test, and Stroop Test. Compositional isotemporal substitution analysis examined associations of SED, LPA, and MVPA with repeated measures of the cognitive function standardized scores. In men, statistical reallocation of 30 minutes of LPA with 30 minutes of MVPA resulted in an estimated difference of SD 0.07 (95% CI, 0.01–0.14), SD 0.09 (95% CI, 0.02–0.17), and SD −0.11 (95% CI, −0.19 to −0.04) in the Digit Symbol Substitution Test, Rey Auditory Verbal Learning Test, and Stroop scores, respectively, indicating better performance. Associations were similar when reallocating time in SED with MVPA, but results were less robust. Reallocation of time in SED with LPA resulted in an estimated difference of SD −0.05 (95% CI, −0.06 to −0.03), SD −0.03 (95% CI, −0.05 to −0.01), and SD 0.05 (95% CI, 0.03– 0.07) in the Digit Symbol Substitution Test, Rey Auditory Verbal Learning Test, and Stroop scores, respectively, indicating worse performance. Associations were largely nonsignificant among women. Conclusions Our findings support the idea that for men, higher‐intensity activities (MVPA) may be necessary in midlife to observe beneficial associations with cognition.

Evidence is scarce for an association between treadmill performance and cognitive function in healthy young and middle-aged adults. We assessed the hypothesis that duration on treadmill predicts cognitive function 25 years later. Participants were from the population-based Coronary Artery Risk Development in Young Adults (CARDIA) study, a multi-center study of black and white men and women aged 18-30 at recruitment in 1985-86 (year 0). The main independent variable of interest was baseline symptom-limited maximal treadmill test duration as a measure of treadmill performance potential, including its major subcomponent cardiorespiratory fitness (CRF/TPP). Cognitive functions measured were verbal memory (with the Rey auditory-verbal learning (AVLT)), psychomotor speed (Digit Symbol Substitution Test (DSST)) and executive function (modified Stroop interference test, where lower is better). We analyzed 2444 participants who had y0 treadmill testing and y25 cognitive testing. For each additional SD of treadmill duration (2.8 minutes), the DSST was 2.4 digits correctly substituted higher, the AVLT was 0.36 words recalled higher, and the Stroop test time 1.7 seconds less, after accounting for race, sex, age, highest attained education level and center of clinic visit( Table ). Further adjustment for dietary pattern, physical activity, smoking, BMI, alcohol consumption, glomerular filtration rate, blood pressure, cholesterol and diabetes status yielded similar trends for these cognitive function tests. In conclusion, CRF/TPP predicts cognitive function 25 years later independently of other factors among apparently healthy adults.

Background: Accumulating evidence suggests the presence of cardiovascular risk factors in middle-age is associated with later adulthood cognitive dysfunction; however, the consequences of suboptimal cardiovascular health in young adulthood are unclear. Methods: The Coronary Artery Risk Development in Young Adults (CARDIA) Study is a cohort of white and black men and women who were 18-30 years when a series of health behaviors (smoking status, body mass index, physical activity, diet) and health factors (total cholesterol, blood pressure, fasting glucose) were measured during a baseline clinic examination in 1985-1986. Included in the current study were 2,577 participants who completed an examination 25 years later when a cognitive battery to assess psychomotor speed (Digit Symbol Substitution Test [DSST]), executive function (modified Stroop Test), and verbal memory (Rey Auditory Verbal Learning Test [RAVLT]) were administered. Ideal levels for each behavior and factor were defined according to the 2020 American Heart Association Goals for Cardiovascular Health. Associations were adjusted for age, sex, race, midlife educational attainment, and study center. Results: At baseline, the percentage of participants with 0-1, 2, 3, 4, 5, and 6-7 ideal health factors were 1.2%, 7.2%, 19.6%, 34.9%, 29.2%, and 7.8%, respectively. Adjusted mean DSST and RAVLT scores were higher among those with a greater number of ideal health factors ( Table ). Each additional factor at the ideal level was associated with a 0.78-point higher DSST score (95% CI: 0.28 to 1.28) and a 0.13-point higher memory score (95% CI: 0.02 to 0.25). Results did not differ by race or sex (p-interaction > 0.05). The ideal cardiovascular health score was not associated with performance on the Stroop Test. Conclusion: In this population-based sample, ideal cardiovascular health in young adulthood was independently associated with cognitive functioning in midlife. Table.

Performance on a German version of the Rey Auditory-Verbal Learning Test (AVLT) was investigated for 64 juvenile patients who were subdivided in 6 clinical groups. In addition to standard evaluation of AVLT protocols which is usually confined to items recalled correctly, an error analysis was performed. Differentiating between total errors (TE), repetition errors (RE), and misnamings (ME), substantial differences between clinical groups could be demonstrated. It is argued that error analysis of verbal memory and learning enriches the understanding of neuropsychological syndromes, and provides additional information for diagnostic and clinical use. Thus, it is possible to gain a more accurate picture so that patients can be appropriately retrained, and research into the functional causes of memory and learning disorders can be intensified.

Objective: The aim of the current study was to estimate the discriminant potential and validity of the Digit Symbol Substitution Test (DSST) of the WAIS-R in the Greek elderly population meeting criteria for subjective cognitive decline (SCD), mild cognitive impairment (aMCI; amnestic subtype), or Alzheimer’s disease dementia (ADD). Method: Four hundred eighty-eight community-dwelling older adults, visitors of the Day Center of Alzheimer Hellas, participated in the study. Two hundred forty-three of them met the criteria for ADD, one hundred eighty-two for aMCI and sixty-three for SCD. Results: Path analysis indicated that the DSST score is affected by age group, educational level, and diagnostic category, but is not affected by gender. The ROC curve analysis showed that the DSST sum score could perfectly differentiate SCD from ADD patients, whereas test’s discriminant potential between aMCI and dementia ADD’s subtype was satisfactory. However, DSST was unable to separate the SCD from the aMCI group. Conclusion: It appears that the DSST is unable to separate the SCD from aMCI population. Therefore, the test in question may be insensitive to incipient cognitive decline. On the contrary, the discriminant potential of the DSST as regards SCD and ADD is excellent, while discrimination between aMCI and ADD is good.

Abstract It remains unclear whether the onset of psychosis is associated with deterioration in cognitive performance. The aim of this study was to examine the course of cognitive performance in an ultrahigh risk (UHR) cohort, and whether change in cognition is associated with transition to psychosis and change in functioning. Consecutive admissions to Personal Assessment and Crisis Evaluation (PACE) Clinic between May 1994 and July 2000 who had completed a comprehensive cognitive assessment at baseline and follow-up were eligible (N = 80). Follow-up ranged from 7.3 to 13.4 years (M = 10.4 years; SD = 1.5). In the whole sample, significant improvements were observed on the Similarities (P = .03), Information (P < .01), Digit Symbol Coding (P < .01), and Trail Making Test-B (P = .01) tasks, whereas performance on the Rey Auditory Verbal Learning Test (Trials 1–3) declined significantly (P < .01) over the follow-up period. Change in performance on cognitive measures was not significantly associated with transition status. Taking time to transition into account, those who transitioned after 1 year showed significant decline on Digit Symbol Coding, whereas those who did not transition improved on this measure (P = .01; effect size [ES] = 0.85). Small positive correlations were observed between improvements in functioning and improvements in performance on Digit Symbol Coding and Arithmetic (0.24, P = .03 and 0.28, P = .01, respectively). In summary, the onset of psychosis was not associated with deterioration in cognitive ability. However, specific findings suggest that immediate verbal learning and memory, and processing speed may be relevant domains for future risk models and early intervention research in UHR individuals.
