Abstract Objective Clinical neuropsychology is an evidence-based discipline that draws heavily from the field’s peer-reviewed journal articles. However, our scientific understanding of the methods and content that comprise the articles published in clinical neuropsychology journals is quite limited. Method A mixed methods approach was used to describe the aims, methods, and content of clinical neuropsychology’s major lifespan journals. Six-hundred articles were randomly sampled from the 2020–2024 volumes of six lifespan clinical neuropsychology journals. All articles were coded across 42 dimensions, including article type, population, design, methods, ability domains, and miscellaneous topics (e.g., brain health). The aims/scope sections of the journals were subjected to qualitative analyses, to identify relevant themes. Results The most common article content was observed in the areas of empirical/data-driven studies, cross-sectional and observational designs, older and neurological participants, cognitive testing of higher-order abilities, and psychometrics/methods. Results showed significant between-journal differences for some of these content areas at broadly medium effect sizes (e.g., experimental design, brain health topics). Qualitative analyses yielded five shared themes, suggesting that the lifespan clinical neuropsychology journals are interested in submissions on brain-behavior relationships, clinical applications, both clinical and healthy/typical populations, professional/guild matters, and multidisciplinary investigations. Conclusions The scientific content published within clinical neuropsychology’s six primary lifespan journals varies in some dimensions, but largely focuses on cross-sectional, observational studies of psychometrics and higher-order cognition. The implications of these findings for future research in clinical neuropsychology are contextualized for authors, reviewers, and readers.

ObjectiveThis study assessed patient‐reported outcomes (PROs) in individuals with persistently positive antiphospholipid antibodies (aPL) to better understand how living with aPL may affect their quality of life.MethodsPatients completed Patient‐Reported Outcomes Measurement Information System Physical Function (PF) and Cognitive Function (CF) Short Forms as well as the pain intensity (PI) rating (scale of 1‐10). Patients were characterized for demographics, clinical manifestations of antiphospholipid syndrome (APS), cardiovascular risk factors, laboratory test results, and medication usage. Multivariate modeling was done via linear regression.ResultsOf 139 patients, 89 had primary APS, 21 had secondary APS, and 29 had persistent aPL without meeting clinical criteria for APS. The average T scores (±SD) for PF and CF were 45.4 ± 9.2 and 48.6 ± 11.6, respectively; the average for PI was 3.0 ± 2.6. Approximately half of the patients (47%) endorsed at least mild impairment in PF (T score < 45). Mean PF, CF, and PI did not differ between diagnostic groups. Individuals who endorsed more impairment on one measure also tended to endorse more impairment on another (Pearson r = 0.43‐0.59). In the multivariate models, age, smoking, pain medications, and serotonergic medications were associated with impairment in at least one PRO domain. The Damage Index for APS was significantly correlated with both PF and CF.ConclusionIndividuals living with APS endorsed more impairment in PF (and potentially CF) than expected for the general population. The relationship between certain medications and PROs warrants further study, as does the longitudinal trajectory of these and other PROs.

Importance Black individuals are more likely than white individuals to develop dementia. Whether higher blood pressure (BP) levels in black individuals explain differences between black and white individuals in dementia risk is uncertain. Objective To determine whether cumulative BP levels explain racial differences in cognitive decline. Design, Setting, and Participants Individual participant data from 5 cohorts (January 1971 to December 2017) were pooled from the Atherosclerosis Risk in Communities Study, Coronary Artery Risk Development in Young Adults Study, Cardiovascular Health Study, Framingham Offspring Study, and Northern Manhattan Study. Outcomes were standardized as t scores (mean [SD], 50 [10]); a 1-point difference represented a 0.1-SD difference in cognition. The median (interquartile range) follow-up was 12.4 (5.9-21.0) years. Analysis began September 2018. Main Outcomes and Measures The primary outcome was change in global cognition, and secondary outcomes were change in memory and executive function. Exposures Race (black vs white). Results Among 34 349 participants, 19 378 individuals who were free of stroke and dementia and had longitudinal BP, cognitive, and covariate data were included in the analysis. The mean (SD) age at first cognitive assessment was 59.8 (10.4) years and ranged from 5 to 95 years. Of 19 378 individuals, 10 724 (55.3%) were female and 15 526 (80.1%) were white. Compared with white individuals, black individuals had significantly faster declines in global cognition (−0.03 points per year faster [95% CI, −0.05 to −0.01]; P = .004) and memory (−0.08 points per year faster [95% CI, −0.11 to −0.06]; P &amp;lt; .001) but significantly slower declines in executive function (0.09 points per year slower [95% CI, 0.08-0.10]; P &amp;lt; .001). Time-dependent cumulative mean systolic BP level was associated with significantly faster declines in global cognition (−0.018 points per year faster per each 10–mm Hg increase [95% CI, −0.023 to −0.014]; P &amp;lt; .001), memory (−0.028 points per year faster per each 10–mm Hg increase [95% CI, −0.035 to −0.021]; P &amp;lt; .001), and executive function (−0.01 points per year faster per each 10–mm Hg increase [95% CI, −0.014 to −0.007]; P &amp;lt; .001). After adjusting for cumulative mean systolic BP, differences between black and white individuals in cognitive slopes were attenuated for global cognition (−0.01 points per year [95% CI, −0.03 to 0.01]; P = .56) and memory (−0.06 points per year [95% CI, −0.08 to −0.03]; P &amp;lt; .001) but not executive function (0.10 points per year [95% CI, 0.09-0.11]; P &amp;lt; .001). Conclusions and Relevance These results suggest that black individuals’ higher cumulative BP levels may contribute to racial differences in later-life cognitive decline.

Background: High blood pressure (BP), particularly in mid-life, increases the risk for late-life cognitive impairment and dementia (CID). The extent to which Blacks’ and Hispanics’ worse BP control starting in young adulthood contributes to their greater risk of CID compared to Whites is uncertain. Objective: To describe a pooled, multi-ethnic cohort created to determine the associations between BP levels over the life course and CID risk in Blacks, Hispanics, and Whites. Methods: We pooled individual-level data from 35,473 adults (22.6% Blacks, 8.1% Hispanics, 67.3% Whites, 2% Other) with baseline age ≥18 and cognitive assessments across 6 longitudinal cohorts in the United States from 1971 to 2016: Atherosclerosis Risk in Communities Study (ARIC), Coronary Artery Risk Development in Young Adults Study (CARDIA), Cardiovascular Health Study (CHS), Framingham Offspring Study (FOS), Multi-Ethnic Study of Atherosclerosis (MESA), and Northern Manhattan Study (NOMAS). We harmonized cognitive tests across studies into 3 factors representing global cognitive performance, executive function, and memory using statistically appropriate confirmatory factor analysis. Mean (SD) follow up was 17.1 (10.9) years. Results: The mean (SD) baseline age was 54.3 (16.4) years and 19554 (55.1%) participants were female (Table). There were 3193 (9.0%) first incident strokes (2651 ischemic, 348 hemorrhagic, and 117 other or undetermined type) and 15147 (42.7%) deaths. The Table presents mean BPs at the first and last visits by cohort and the pooled sample. From the initial to the last assessment, mean global cognition decreased over time (p<0.001), as did mean executive function (p<0.001) and mean memory scores (p<0.001) in the pooled sample. Conclusion: This will be the first comprehensive, large investigation of the association of BP levels from young adulthood to late-life and CID risk in Blacks, Hispanics, and Whites.
