Remote assessment of cognitive dysfunction in hematologic malignancies using web‐based neuropsychological testing
Background Cognitive impairment is a frequent adverse effect of cancer and its therapies. As neuropsychological assessment is not often standard of care for patients with non‐CNS disease, efficient, practical assessment tools are required to track cognition across the disease course. We examined cognitive functioning using a web‐based cognitive testing battery to determine if it could detect differences between patients with cancer and controls. Methods We enrolled 22 patients with multiple myeloma (MM) or non‐Hodgkin lymphoma (NHL) and 40 healthy controls (mean age = 56 ± 11 years, 52% male). Participants completed the BrainCheck cognitive testing battery and online versions of select measures from the Patient Reported Outcome Measures Information System (PROMIS) during a video conference. MANOVA was used to compare BrainCheck and PROMIS scores between groups controlling for age and sex. An exploratory linear regression analysis was conducted within the cancer group to determine potential contributors to cognitive functioning. Results All participants except for one control completed the online assessment measures without difficulty. Compared to controls, the cancer group demonstrated significantly lower scores in objective and subjective cognitive function, physical functioning, and social role performance and elevated fatigue scores. Corticosteroid treatment, immunotherapy, lower physical functioning, lower income, and older age significantly contributed to lower cognitive function (adjusted R2 = 0.925, F = 19.63, p = 0.002). Conclusion Remote assessment of cognitive and psychosocial functioning is feasible with patients with cancer following treatments. The BrainCheck cognitive testing battery has the potential to detect differences in cognition between patients with cancer and controls. Cancers and their treatments can result in impaired brain function. Evaluating brain function can be challenging due to feasibility and resource limitations. We remotely administered a web‐based, commercially available cognitive testing battery and demonstrated that patients scored significantly lower than controls. Immunotherapy, high dose steroids, older age, lower physical function, and lower income level were associated with lower cognitive function. Remote assessment of cognitive function is feasible in patients with cancer and could increase availability of brain function surveillance.
Evidence of compensatory neural hyperactivity in a subgroup of breast cancer survivors treated with chemotherapy and its association with brain aging
Chemotherapy-related cognitive impairment (CRCI) remains poorly understood in terms of the mechanisms of cognitive decline. Neural hyperactivity has been reported on average in cancer survivors, but it is unclear which patients demonstrate this neurophenotype, limiting precision medicine in this population. We evaluated a retrospective sample of 80 breast cancer survivors and 80 non-cancer controls, aged 35-73, for which we had previously identified and validated three data-driven, biological subgroups (biotypes) of CRCI. We measured neural activity using the z-normalized percent amplitude of fluctuation from resting-state functional magnetic resonance imaging (MRI). We tested established, quantitative criteria to determine whether hyperactivity can accurately be considered compensatory. We also calculated the brain age gap by applying a previously validated algorithm to anatomic MRI. We found that neural activity differed across the three CRCI biotypes and controls (  = 13.5,  < 0.001), with Biotype 2 demonstrating significant hyperactivity compared to the other groups (  < 0.004, corrected), primarily in prefrontal regions. Alternatively, Biotypes 1 and 3 demonstrated significant hypoactivity (  < 0.02, corrected). Hyperactivity in Biotype 2 met several of the criteria to be considered compensatory. However, we also found a positive relationship between neural activity and the brain age gap in these patients (r = 0.45,  = 0.042). Our results indicated that neural hyperactivity is specific to a subgroup of breast cancer survivors and, while it seems to support preserved cognitive function, it could also increase the risk of accelerated brain aging. These findings could inform future neuromodulatory interventions with respect to the risks and benefits of upregulation or downregulation of neural activity.
Altered functional brain connectivity, efficiency, and information flow associated with brain fog after mild to moderate COVID-19 infection
COVID-19 is associated with increased risk for cognitive decline but very little is known regarding the neural mechanisms of this risk. We enrolled 49 adults (55% female, mean age = 30.7 ± 8.7), 25 with and 24 without a history of COVID-19 infection. We administered standardized tests of cognitive function and acquired brain connectivity data using MRI. The COVID-19 group demonstrated significantly lower cognitive function (W = 475, p < 0.001, effect size r = 0.58) and lower functional connectivity in multiple brain regions (mean t = 3.47 ±0.36, p = 0.03, corrected, effect size d = 0.92 to 1.5). Hypo-connectivity of these regions was inversely correlated with subjective cognitive function and directly correlated with fatigue (p < 0.05, corrected). These regions demonstrated significantly reduced local efficiency (p < 0.026, corrected) and altered effective connectivity (p < 0.001, corrected). COVID-19 may have a widespread effect on the functional connectome characterized by lower functional connectivity and altered patterns of information processing efficiency and effective information flow. This may serve as an adaptation to the pathology of SARS-CoV-2 wherein the brain can continue functioning at near expected objective levels, but patients experience lowered efficiency as brain fog.
Cancer-related cognitive impairment in racial and ethnic minority groups: a scoping review
Purpose Disparities in cognitive function among racial and ethnic groups have been reported in non-cancer conditions, but cancer-related cognitive impairment (CRCI) in racial and ethnic minority groups is poorly understood. We aimed to synthesize and characterize the available literature about CRCI in racial and ethnic minority populations. Methods We conducted a scoping review in the PubMed, PsycInfo, and Cumulative Index to Nursing and Allied Health Literature databases. Articles were included if they were published in English or Spanish, reported cognitive functioning in adults diagnosed with cancer, and characterized the race or ethnicity of the participants. Literature reviews, commentaries, letters to the editor, and gray literature were excluded. Results Seventy-four articles met the inclusion criteria, but only 33.8% differentiated the CRCI findings by racial or ethnic subgroups. There were associations between cognitive outcomes and the participants’ race or ethnicity. Additionally, some studies found that Black and non-white individuals with cancer were more likely to experience CRCI than their white counterparts. Biological, sociocultural, and instrumentation factors were associated with CRCI differences between racial and ethnic groups. Conclusions Our findings indicate that racial and ethnic minoritized individuals  may be disparately affected by CRCI. Future research should use standardized guidelines for measuring and reporting the self-identified racial and ethnic composition of the sample; differentiate CRCI findings by racial and ethnic subgroups; consider the influence of structural racism in health outcomes; and develop strategies to promote the participation of members of racial and ethnic minority groups.
Reasons for Perceived Everyday Discrimination, Quality of Life, and Psychosocial Health of Breast Cancer Survivors: A Cross-Sectional Cluster Analysis
Introduction Discrimination exacerbates disparities among breast cancer survivors (BCS), yet how different reasons for experiencing perceived discrimination (e.g., race, age) influence health remains understudied. We explored the association between self-reported discrimination, psychosocial health, and quality of life (QOL), identified clusters based on reasons for perceived discrimination, and examined differences in QOL and psychosocial outcomes between these clusters. Methods In this cross-sectional study, we examined correlations between reasons for perceived discrimination (Everyday Discrimination Scale; EDS), QOL domains (cognitive, physical, social, emotional, and functional QOL measured with FACT-G), social dysfunction (Social Difficulties Inventory), and a psychological distress composite score (included measures of stress [Perceived Stress Scale], anxiety [PROMIS Anxiety], and depression [PROMIS Depression]), among 174 breast cancer survivors (stage 0-IV; ≥21 years). We used k-modes clustering to identify discrimination groups. Differences in demographics, clinical characteristics, and outcomes across clusters were assessed using Chi-square, analysis of variance, covariance, or non-parametric tests, followed by post hoc analyses. Results Overall, experiences of discrimination were associated with poorer QOL and psychosocial health (|0.306| 0.05). Conclusion QOL and psychosocial health scores varied between clusters based on reasons for perceived discrimination. Future interventions to improve QOL for breast cancer survivors should consider addressing stigma related to gender, physical appearance, and other forms of discrimination.
Feasibility, reliability and validity of smartphone administered cognitive ecological momentary assessments in breast cancer survivors
Breast cancer and its treatment are associated with cancer-related cognitive impairments (CRCI). Cognitive ecological momentary assessments (EMA) allow for the assessment of individual subjective and objective cognitive functioning in real world environments and can be easily administered via smartphones. The objective of this study was to establish the feasibility, reliability, and validity of a cognitive EMA platform, NeuroUX, for assessing CRCI in breast cancer survivors. Using a prospective design, clinical cognitive assessments (neuropsychological testing; patient reported outcomes) were collected at baseline, followed by an 8-week EMA smartphone protocol assessing self-reported cognitive concerns and objective cognitive performance via mobile cognitive tests once per day, every other day. Satisfaction and feedback questions were included in follow-up data collection. Feasibility data were analyzed using descriptive methods. Test-retest reliability was examined using intraclass correlation coefficients for each cognitive EMA (tests and self-report questions), and Pearson's correlation was used to evaluate convergent validity between cognitive EMAs and baseline clinical cognitive variables. 105 breast cancer survivors completed the EMA protocol with high adherence (87.3%) and high satisfaction (mean 87%). Intraclass correlation coefficients for all cognitive EMAs were strong (>0.73) and correlational findings indicated moderately strong convergent validity (|0.23| <   < |0.61|). Fully remote, self-administered cognitive testing for 8-weeks on smartphones was feasible in breast cancer survivors who completed adjuvant treatment and the specific cognitive EMAs (cognitive EMA tests and self-report questions) administered demonstrate strong reliability and validity for CRCI.
Feasibility and psychometric quality of smartphone administered cognitive ecological momentary assessments in women with metastatic breast cancer
Objective Metastatic breast cancer (MBC) is associated with burdensome side effects, including cognitive changes that require ongoing monitoring. Cognitive ecological momentary assessments (EMAs) allow for assessment of individual cognitive functioning in natural environments and can be administered via smartphones. Accordingly, we sought to establish the feasibility, reliability, and validity of a commercially available cognitive EMA platform. Methods Using a prospective design, clinical cognitive and psychosocial assessments (cognitive batteries; patient reported outcomes) were collected at baseline, followed by a 28-day daily EMA protocol that included self-ratings for symptoms and mobile cognitive tests (memory, executive functioning, working memory, processing speed). Satisfaction and feedback questions were included in follow-up data collection. Feasibility data were analyzed using mixed descriptive methods. Test-retest reliability was examined using intraclass correlation coefficients (ICCs) for each EMA, and Pearson's correlation were used to evaluate convergent validity between cognitive EMAs and baseline clinical cognitive and psychosocial variables. Results Fifty-one women with MBC (n = 51) completed this EMA study. High satisfaction (median 90%), low burden (median 19%), high adherence rates (mean 94%), and 100% retention rate were observed. ICCs for cognitive tests of working memory, executive function, and processing speed were robust (>0.90) and ICC for memory tests acceptable (>0.66). Other correlational findings indicated strong convergent validity for all cognitive and psychosocial EMAs. Conclusion Cognitive EMA monitoring for 28 days is feasible and acceptable in women with MBC, with specific cognitive EMAs (mobile cognitive tests; cognitive function self-ratings) demonstrating strong reliability and validity.
Characterizing cancer-related cognitive impairments and impact on quality of life in women with metastatic breast cancer
Purpose Little is known about cancer-related cognitive impairments (CRCI) in women with metastatic breast cancer (MBC). The purpose of this study is to (1) comprehensively describe CRCI and any associated psychosocial and behavioral symptoms, (2) determine observable sociodemographic and clinical risk factors for CRCI, and (3) explore cognitive and psychosocial predictors of quality of life and social functioning in women living with MBC. Methods Using a cross-sectional design, women with MBC completed assessments (objective and subjective measures of CRCI including 3 open-ended questions, measures of psychosocial and behavioral factors, and assessments of quality of life and social function), and data were analyzed using descriptive statistics, qualitative content analysis, correlation analyses, t tests, analysis of variance, and linear regression models. Results Data from 52 women were analyzed. 69.2% of the sample reported clinically significant CRCI and 46% of the sample scored < 1 standard deviation below the standardized mean on one or more cognitive tests. Those with triple-negative MBC (compared to HER2+), recurrent MBC (compared to de novo), and no history of chemotherapy had worse subjective CRCI, and those without history of surgery and older age had worse objective CRCI. Subjective CRCI, but not objective CRCI, was significantly associated with quality of life and social functioning. Conclusion Subjective and objective CRCI are likely a common problem for those with MBC. Subjective CRCI is associated with poorer quality of life and lower social functioning. Healthcare providers should acknowledge cognitive symptoms, continually assess cognitive function, and address associated unmet needs across the MBC trajectory.
The effect of non-pharmacological interventions on cognitive function in cancer: an overview of systematic reviews
Purpose A significant number of cancer survivors experience cancer-related cognitive impairment (CRCI), which can impact their ability to think, reason, make decisions, and perform daily actions. In recent years, non-pharmacological interventions for CRCI have gained significant attention. These interventions include exercise, cognitive behavioural therapy, cognitive training/remediation, dietary, mind–body, and multi-modal/complex interventions. This umbrella review provides a critical overview to inform guidelines and current practice, identify the most promising interventions, and uncover gaps in the research literature. Methods This umbrella review of systematic reviews was pre-registered on Open Science Framework and PROSPERO. Six databases were searched. Systematic reviews (SR) assessing any non-pharmacological interventions to improve cognition in cancer (any type) were included. The overview followed gold-standard guidelines and recommendations. The results were narratively synthesised, and descriptive statistics and effect size ranges were calculated. Results Sixty-four ( n  = 64) SRs were included. Results were synthesised into four non-pharmacological domains. Cognitive training/rehabilitation had the strongest evidence for efficacy. Physical activity/exercise showed promising efficacy; however, the variability of findings was considerable. Mind–body and psychological/behavioural therapy interventions were limited, but there was evidence for short-term effectiveness. Multi-modal/complex interventions showed potential for improving cognition in cancer but were poorly defined. Conclusions Overall, non-pharmacological interventions demonstrated efficacy for improving cognition in cancer. There were limited intervention characteristics within domains which were consistently related to efficacy. Three key recommendations are provided for future research: (1) adopt harmonisation and reporting guidelines; (2) develop definitional guidelines of cognitive domains for CRCI research; and (3) assess intervention and participant characteristics associated with positive versus null/negative findings.
A Telehealth-Based Behavioral Intervention for Cancer-Related Cognitive Decline in Older Adults Undergoing Systemic Therapy for Breast Cancer: Development and Usability Testing
Cancer-related cognitive decline (CRCD) is a significant problem; interventions are needed to mitigate CRCD for older adults (aged ≥65 years). Our objective was to develop and evaluate the usability of Memory and Attention Adaptation Training-Geriatrics (MAAT-G), a CRCD intervention for older adults with breast cancer undergoing systemic treatment. We conducted an intervention adaptation study to develop MAAT-G. MAAT-G is a cognitive behavioral therapy-based intervention delivered by a health professional over the course of 10 weekly individual workshops via videoconferencing. To develop MAAT-G, the contextual, cohort-based, maturity, and specific challenge framework was used for preliminary adaptations. Patient advocate collaborators guided further refinement, reviewing MAAT-G workshop content, the participant workbook, and intervention delivery via videoconferencing to optimize relevance and usability for older adults. The usability of MAAT-G and its videoconferencing delivery were subsequently evaluated in 4 older adults with breast cancer using the System Usability Scale (score range 0-100; >67 being above average) and through semistructured qualitative interviews. Numerous adaptations were made to address the unique needs of older patients using the contextual, cohort-based, maturity, and specific challenge framework and patient advocate feedback. Usability testing included 4 female patients with breast cancer (mean age 73.3, SD 3.77; range 67-77 years). Patients were receiving systemic therapy (2 receiving adjuvant therapy and 2 receiving advanced-stage disease therapy). One patient had an educational level lower than high school; 3 had some college education or higher. All 4 patients completed study procedures, including 10 MAAT-G workshop sessions (100% intervention adherence). The mean System Usability Scale score was 90.6 (SD 13.51), indicating good usability. MAAT-G is a behavioral intervention developed to mitigate CRCD. It is designed specifically for older adults and showed above-average usability in this population.
