RESUMO
PURPOSE: Research suggests that cancer-related cognitive impairment (CRCI) can occur before breast cancer (BC) treatment. The limited extant evidence suggests the underlying mechanisms could be stress-related. Potential psychological and biological predictors of CRCI prior to any BC treatment were examined. METHODS: 112 treatment-naïve women with BC and 67 healthy controls (HC) completed a neuropsychological test battery to assess cognitive impairment and a self-report battery to assess cognitive complaints, cancer-related stress, depressive and anxiety symptoms. Morning and evening cortisol and α-amylase were collected from saliva. Multilinear regressions were conducted. RESULTS: Treatment-naïve BC patients were more frequently impaired in verbal memory and processing speed and reported more cognitive complaints (all p < .001) than HC. BC patients and HC did not differ in overall cognitive impairment (p = .21). Steeper α-amylase, lower cancer-related stress and younger age was associated with better overall cognitive function in treatment-naïve BC patients. Higher depressive symptoms predicted higher levels of cognitive complaints in BC patients. CONCLUSION: Overall, these findings suggest that stress plays a role in CRCI. This study is the first to associate α-amylase with cognitive function in cancer patients, informing future research. The findings on impairment in processing speed and verbal memory among treatment-naïve BC highlight the need to screen for such impairments among BC patients and indicate that future studies on CRCI should include baseline assessments prior to BC treatment. If replicated, these findings could inform the development and testing of appropriate interventions to decrease CRCI among cancer patients.

Advances in diagnostics and treatment of childhood cancer during the past few decades have substantially increased survival, resulting in a growing population of survivors of childhood cancer. Somatic and mental late effects of the cancer and the treatment may impact the quality of life (QoL). Previous reviews of QoL in survivors of childhood cancer have shown contradictory findings across studies and the majority of studies included have been based on data from North America and may not be directly comparable to a European setting. The aim of our study was to critically evaluate and summarise the latest evidence on the QoL of childhood cancer survivors in Europe and to identify survivors at particular risk. The eligible studies were published between 2008 and 2022, conducted in Europe and included participants who had survived at least 5 years after diagnosis of a childhood cancer. The main outcome of interest was QoL of survivors which was measured with validated qualitative and quantitative QoL questionnaires. A systematic literature search conducted in PubMed, EMBASE, PsycINFO and CINALH resulted in inclusion of 36 articles with a total of 14 342 survivors of childhood cancer. The majority of included studies found that childhood cancer survivors reported poorer QoL than comparisons. Female gender, treatment with haematopoietic stem cell transplantation and a brain tumour diagnosis were associated with lower QoL. With a growing population of childhood cancer survivors with many years ahead of them, targeted interventions and optimal follow-up care are important to improve the QoL of survivors.

OBJECTIVE: Improved survival rates have made it increasingly important for clinicians to focus on cancer survivorship issues affecting the quality of life of melanoma patients. To provide a comprehensive overview of the disease and treatment-related issues affecting such patients, we conducted a systematic review and meta-analysis of the literature to estimate the prevalence of symptoms of depression, anxiety, fatigue, sleep disturbance, and cognitive problems among melanoma patients, both uveal and cutaneous, before, during and after treatment. METHODS: The review was preregistered with PROSPERO (#CRD42020189847) and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of the literature published up until June 2022 was undertaken using PubMed, PsycInfo, the Cochrane Library, and CINAHL. Two independent reviewers screened 1418 records and quality-rated included studies. The reported prevalence rates of symptoms were pooled using a random-effects model. RESULTS: Sixty-six studies including a total of 12,400 melanoma patients published between 1992 and 2022 were included. Pooled prevalence rates ranged from 6% to 16% for depression and 7%-30% for anxiety across diagnoses (uveal and cutaneous melanoma) and assessment time points. One third of the patients (35%) reported clinically significant fatigue, 20%-44% had cognitive complaints, while prevalence of sleep disturbance was not reported. Quality assessment indicated that 80% of the studies were of good quality. CONCLUSION: A large body of research shows that depression and anxiety symptoms are prevalent in melanoma patients before, during and after treatment. However, research examining other symptoms known to affect quality of life, such as fatigue, sleep disturbances, and cognitive problems, is still needed.

BACKGROUND: Evidence suggests that patients with prostate cancer (PCPs) receiving androgen-deprivation therapy (ADT) are at risk for cognitive impairment. Research with other populations with cancer indicates that cognitive impairment may also occur before systemic treatment. The authors assessed cognitive impairment in untreated PCPs referred to ADT and explored associations with structural brain networks, endocrine status, and selected genotypes. METHODS: Forty untreated PCPs and 27 healthy controls (HCs) who completed a questionnaire package underwent neuropsychological testing, magnetic resonance imaging, and blood sampling. Cognitive impairment was defined as a z score ≤-2 on 1 neuropsychological test or ≤-1.5 on 2 neuropsychological tests. Structural brain networks were investigated using diffusion-weighted imaging and graph theory. Associations of cognitive performance with patient-reported outcome measures (PROMs), brain networks, testosterone levels, and genotypes (apolipoprotein ε [APOE], catechol-O-methyltransferase [COMT], and brain-derived neurotrophic factor [BDNF]) were explored. RESULTS: PCPs performed poorer than HCs on 7 of 15 neuropsychological tests and exhibited a higher frequency of cognitive impairment (57.5% vs 22.2%; P ≤ .01 to .03). All neuropsychological outcomes were associated with ≥1 PROM (P ≤ .01 to .04). Compared with the HC group, the PCP group exhibited altered global network organization as well as disrupted regional network characteristics in frontal and temporal regions (P < .01). PCPs had lower testosterone levels (P < .01) than HCs, which correlated with better visuospatial performance (r = -0.33; P = .04). No effects were found of APOE, COMT, or BDNF. CONCLUSIONS: The current results suggest that untreated PCPs may demonstrate cognitive impairment and that psychological and behavioral symptoms (PROMs), as well as impairment in structural brain networks, might be the underlying mechanisms.

Background: Cancer and cancer treatments may impact the brain through several pathways leading to cognitive impairment. Neuroimaging evidence has begun to elucidate the neurobiological underpinnings of cancer-related cognitive impairment. The aim of this paper was to systematically review available literature on structural brain alterations following adult non-central nervous system (CNS) cancers and associated treatments. Methods: This review followed PRISMA guidelines and was registered in PROSPERO (ID#107387). Comprehensive searches were conducted in June 2018 using PubMed and Web of Science. Inclusion criteria were English peer-reviewed journal articles of formal, controlled studies that examined structural neuroimaging outcomes in adult non-CNS cancer patients and survivors. Selected articles were assessed for quality and risk of bias using the National Institutes of Health Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Results: Thirty-six publications of prospective and cross-sectional studies met inclusion criteria and were included. Structural brain alterations following cancer and its treatment were reported in a majority of the publications as evidenced by reduced global and local gray matter volumes, impaired white matter microstructural integrity, and brain network alterations. Structural alterations were most often evident when cancer-treated groups were compared with healthy controls, and more subtle when compared with cancer controls. Regarding the existence of pretreatment impairments, the evidence was equivocal. There was significant between-study heterogeneity in imaging analytical approaches and use of statistical adjustments. Over half reported associations with cognitive outcomes, though regions and associated cognitive domains were heterogeneous. Conclusions: Structural brain alterations following cancer and cancer treatments were reported in a majority of the reviewed studies. However, the extent of observed alterations depended on the choice of comparison groups. Methodological issues exist that will need to be addressed systematically to ensure the validity of findings. Large-scale prospective studies with extended assessment points are warranted to replicate and build upon initial findings.

Background: Fear of cancer recurrence (FCR) in patients and their spouses is associated with reduced quality of life, but little is known about longitudinal dyadic associations of FCR between them. This study examined (i) the trajectory of FCR from pre-treatment to 12 months later; (ii) dyadic associations of FCR over time; and (iii) whether cancer treatment type predicted later FCR among prostate cancer patients and their spouses. Methods: Sixty-nine patients and 71 spouses of patients with localized prostate cancer completed a FCR measure at baseline (pre-treatment), 6 months and 12 months later (post-treatment). A repeated measures linear mixed model was used to examine FCR trajectories. Actor-partner interdependence models (APIMs) were conducted on the 52 couples with complete data to examine actor and partner effects and treatment type on subsequent FCR. Results: Patients and spouses reported moderate FCR levels over time, though spouses' FCR was significantly higher than patients' FCR (p < .001). FCR declined significantly for both groups over time (p < .001). APIMs demonstrated significant actor effects in baseline to 6 month, and 6-12 month models. Surgery was significantly associated with lower spouse FCR at 6 months, and radiation with lower patient FCR at 12 months. Conclusions: This is the first study to have concurrently examined FCR longitudinally in prostate cancer patients and spouses. Patients' and spouses' FCR declined from pre- to post-treatment, with spouses experiencing greater FCR than patients over time. FCR in patients and spouses did not appear to impact one another over time. Treatment type impacted FCR in patients and spouses differently.

Background: Cancer-related cognitive impairment (CRCI) is a commonly reported complaint among non-CNS cancer patients. Even subtle CRCI may have detrimental effects on quality of life and identifying patients at increased risk for CRCI to improve survivorship care is important. In the present paper, we systematically reviewed available studies of possible genetic risk factors for developing CRCI. Methods: Keyword-based systematic searches were undertaken on 24 July 2018 in PubMed, Web of Science, The Cochrane Library, and CINAHL. Three authors independently evaluated full-texts of identified papers and excluded studies with registration of reasons. Seventeen studies reporting results from 14 independent samples were included for review. Two authors independently quality assessed the included studies. The review was preregistered with PROSPERO (CRD42018107689). Results: Ten studies investigated apolipoprotein E (APOE), with four studies reporting that carrying at least one risk allele (APOE4 (ε4)) was associated with CRCI, while six studies found no association. The remaining identified genetic risk variants associated with CRCI located in: COMT, four DNA repair genes, five oxidative stress genes, 22 genes related to breast cancer phenotype, and GNB3. No associations were found between CRCI and genes coding for interleukin-6 (IL6), tumor necrosis factor alpha (TNF), interleukin 1 beta (IL1B), and brain-derived neurotropic factor (BDNF). With the exception of APOE, the genetic risk factors had only been investigated in one or two studies each. Conclusions: Overall, the available evidence of possible genetic risk factors for CRCI is limited. While some research suggests a role for the ε4 allele, the literature is generally inconsistent, and the currently available evidence does not allow clear-cut conclusions regarding the role of genetic factors in the development of CRCI. Larger genetic studies and studies investigating additional genetic variants are needed to uncover genetic risk factors for CRCI.

Background: The extent of radiation therapy (RT)-induced changes in cognitive function is unknown. RT with protons instead of photons spares the healthy brain tissue more and is believed to reduce the risk of cognitive dysfunction. There is modest knowledge on which parts of the brain we need to spare, to prevent cognitive dysfunction. To uncover which cognitive domains is most affected, we compared cognitive functioning in brain tumor patients treated with neurosurgery and RT with brain tumor patients treated with neurosurgery alone. Methods: A cross-sectional study assessing cognitive function in 110 patients with a primary brain tumor grades I-III or medulloblastoma (grade IV) treated at Aarhus University Hospital (AUH), Denmark between 2006 and 2016. Two cohorts were established: a cohort of 81 brain tumor patients who had received neurosurgery followed by RT (RT+), and a cohort of 29 brain tumor patients who had only received neurosurgery (RT-). The patients underwent questionnaires and neuropsychological assessment with standardized tests. Results: Mean age was 53.5 years with an average time since diagnosis of 7.3 years. Compared with normative data, lower average scores were observed for the entire group on domains concerning of verbal learning and memory (p < .001), attention and working memory (p < .001), processing speed (p < .001), and executive functioning (p < .001). Compared to RT- patients, RT + patients scored lower on domains concerning processing speed (p = .04) and executive function (p = .05) and had higher impairment frequency on verbal fluency (p = .02) with 16% of patients exceeding 1.5 SD below normative data. Conclusions: Our results indicate that treatment, including RT, for a primary brain tumor may have negative long-term impact on cognitive function, especially on processing speed and executive function.

OBJECTIVE: Hematopoietic stem cell transplant (HSCT) survivors may show evidence of objective cognitive impairment; however, perceived cognitive problems and their impact on quality of life are less well-understood. The purpose of this study was to explore HSCT survivors' perceptions of cognitive impairment and its effect on daily life functioning. METHOD: Sixty-nine autologous and allogeneic HSCT survivors nine months to three years posttransplant experiencing mild survivorship problems completed a brief structured interview regarding perceived cognitive impairment since transplant. Data were coded and content analyzed. The frequency of participants reporting cognitive problems by domain and associations between reports of cognitive problems and age, depressed mood, anxiety, and health-related quality of life were examined. RESULT: Overall, 49 of the 69 participants (71%) reported cognitive impairments after transplant: 38 in memory (55%), 29 in attention and concentration (42%), and smaller numbers in other domains. There were no significant differences in problems reported by transplant type. Of the 50 participants who worked before transplant, 19 (38%) did not return to work following transplant, with 12 citing cognitive and health problems as being the reason. There were significant associations between reports of cognitive impairment and younger age (p = 0.02), depressed mood (p = 0.02), anxiety (p = 0.002), and health-related quality of life (p = 0.008). SIGNIFICANCE OF RESULTS: A large proportion of survivors reported cognitive impairment following HSCT that impaired daily life functioning. Perceived cognitive impairment was associated with younger age, greater distress and reduced health-related quality of life.

OBJECTIVE: Our aim was to assess with positron emission tomography (PET) the temporal and spatial inter-relationships between levels of cortical microglial activation and the aggregated amyloid-ß and tau load in mild cognitive impairment (MCI) and early Alzheimer's disease (AD). METHODS: Six clinically probable AD and 20 MCI subjects had inflammation (11C-(R)-PK11195), amyloid (11C-PiB) and tau (18F-flortaucipir) PET, magnetic resonance imaging (MRI) and a neuropsychological assessment. Parametric images of tracer binding were interrogated at a voxel level and by region of interest analyses. RESULTS: 55% of MCI and 83% of AD subjects had a high amyloid-ß load. We have previously reported that clusters of correlated amyloid and inflammation levels are present in cortex. Here we found no correlation between levels of inflammation (11C-(R)-PK11195 BPND) and tau (18F-flortaucipir SUVR) or MMSE scores in high amyloid-ß cases. INTERPRETATION: While correlated levels of amyloid-ß and inflammation can be seen in MCI, we did not detect an association between levels of cortical tau tangles and inflammation in our series of high amyloid-ß cases. High levels of inflammation could be seen in amyloid-ß positive MCI cases where 18F-flortaucipir signals were low suggesting microglial activation precedes tau tangle formation. Inflammation levels were higher in high amyloid-ß MCI than in early AD cases, compatible with it initially playing a protective role.

See Kreisl (doi:10.1093/awx151) for a scientific commentary on this article.Subjects with mild cognitive impairment associated with cortical amyloid-ß have a greatly increased risk of progressing to Alzheimer's disease. We hypothesized that neuroinflammation occurs early in Alzheimer's disease and would be present in most amyloid-positive mild cognitive impairment cases. 11C-Pittsburgh compound B and 11C-(R)-PK11195 positron emission tomography was used to determine the amyloid load and detect the extent of neuroinflammation (microglial activation) in 42 mild cognitive impairment cases. Twelve age-matched healthy control subjects had 11C-Pittsburgh compound B and 10 healthy control subjects had 11C-(R)-PK11195 positron emission tomography for comparison. Amyloid-positivity was defined as 11C-Pittsburgh compound B target-to-cerebellar ratio above 1.5 within a composite cortical volume of interest. Supervised cluster analysis was used to generate parametric maps of 11C-(R)-PK11195 binding potential. Levels of 11C-(R)-PK11195 binding potential were measured in a selection of cortical volumes of interest and at a voxel level. Twenty-six (62%) of 42 mild cognitive impairment cases showed a raised cortical amyloid load compared to healthy controls. Twenty-two (85%) of the 26 amyloid-positive mild cognitive impairment cases showed clusters of increased cortical microglial activation accompanying the amyloid. There was a positive correlation between levels of amyloid load and 11C-(R)-PK11195 binding potentials at a voxel level within subregions of frontal, parietal and temporal cortices. 11C-(R)-PK11195 positron emission tomography reveals increased inflammation in a majority of amyloid positive mild cognitive impairment cases, its cortical distribution overlapping that of amyloid deposition.

PURPOSE: Prostate cancer patients who have undergone androgen deprivation therapy (ADT) may experience cognitive impairment, yet there is an unmet need for nonpharmacological interventions to address cognitive impairment in this population. This study examines the feasibility, acceptability, and preliminary efficacy of a home-based computerized cognitive training (CCT) program to treat cancer-related cognitive impairment. METHODS: Sixty men who had received ≥ 3 months of ADT were screened for at least mild cognitive or neurobehavioral impairment and randomized to 8 weeks of CCT or usual care. Follow-up assessments occurred immediately post-intervention or equivalent (T2) and 8 weeks later (T3). The acceptability of CCT was also assessed. RESULTS: Feasibility:A priori feasibility thresholds were partially met (i.e., randomization rate > 50%, retention rate > 70% excluding CCT drop-outs, but < 70% for intent-to-treat). Acceptability: Participants were mostly satisfied with CCT and found it somewhat enjoyable, though barriers to uptake existed. Preliminary efficacy: Linear mixed models indicated significant time by group effects favorable to CCT in reaction time (p = .01), but unfavorable to CCT in verbal and visual memory (ps < .05). Memory was temporarily suppressed in the CCT group at T2, but normalized by T3. There was no effect of CCT on self-reported cognitive functioning, neurobehavioral functioning, nor quality of life. CONCLUSIONS: This study provides tentative support for the feasibility and acceptability of CCT to treat mild cognitive impairment in ADT patients. CCT had a beneficial effect on reaction time, but temporarily suppressed memory. CCT's benefits may be limited to a narrow area of functioning. Larger-scale studies are needed.

OBJECTIVE: The aim of this study was to determine the prevalence of cognitive impairment (CI) in newly diagnosed and orchiectomized testicular cancer (TC) patients prior to systemic treatment, and to explore biological and psychological correlates. METHODS: Sixty-six TC patients were compared with 25 healthy men on neuropsychological tests and a measure of cognitive complaints. CI status and a global composite score (representing overall neuropsychological performance) were calculated for each participant. Possible psychological (depression, anxiety, stress, and post-traumatic stress symptoms) and biological (cortisol, IL-6, TNF-α, and CRP) correlates and predictors of patients' cognitive functioning were explored. RESULTS: TC patients had lower scores on 6 out of 11 neuropsychological outcomes (p < 0.01) in processing speed, attention, and working memory, verbal learning and memory, and verbal fluency. Prevalence of CI among TC patients was 58%, significantly exceeding the frequency in healthy men (p < 0.01). Patients' cortisol levels predicted overall neuropsychological performance (p = 0.04). Cognitive complaints were associated with IL-6 (p = 0.02) and all psychological distress measures (p < 0.001). CONCLUSIONS: The prevalence of CI in recently orchiectomized TC patients was unexpectedly high with patients performing more poorly than healthy controls on a majority of neuropsychological outcomes. Cortisol is a potential predictor of neuropsychological performance in TC patients prior to cytotoxic treatment.

PURPOSE: The aim of the present study was to determine the prevalence of cognitive impairment (CI) in a group of testicular (TC) survivors by comparing their neuropsychological test scores with normative data and to assess their performance in specific cognitive domains. METHODS: Seventy-two TC survivors were evaluated 2 to 7 years post-treatment with a neuropsychological test battery that assessed multiple cognitive domains-attention and working memory, processing speed, verbal fluency, learning and memory, and executive functioning. Test scores were compared with normative data, and CI status was calculated for each participant. RESULTS: In group-level analyses, survivors exhibited significantly impaired scores on a majority (9/12) of the neuropsychological outcomes (p < 0.01). In individual-level analyses, 62.5 % of the survivors were classified as having CI, significantly exceeding the expected normative frequency of 25 % (binomial test: p < 0.001). In particular, CI was observed in multiple outcomes related to verbal learning and memory (29 to 33 % of participants), visual learning and memory (14-28 %), processing speed (8-24 %), executive functioning (17 %), and attention and working memory (4-15 %). No association was found between treatment modality (surgery ± chemotherapy) and CI. CONCLUSIONS: The prevalence of CI in TC survivors was unexpectedly high, with survivors performing significantly worse than expected on a majority of the neuropsychological outcomes. While the findings are preliminary in nature, they still have important implications for the diagnosis and treatment of CI in TC survivors.

People are generally poor at remembering complex food stimuli, such as wine. While writing a description has been shown to improve memory performance, talking about wine is generally a difficult task for novices. However, giving novices a framework in which to evaluate the wine may help with the memory process. Using a short-term recognition task, this experiment compared different forms of wine evaluation on the to-be-remembered wine sample, using either 1) a classic smell and taste evaluation, 2) a multisensory metaphor selection task with visual, auditory, and tactile metaphors, or 3) a control condition with no writing. Results from 153 participants revealed that recognition performance between the three groups was not significantly different. Secondary analysis revealed that recognition accuracy was correlated with wine liking for the control group, suggesting that in the absence of explicitly evaluating the wine, participants relied on wine liking as a cue for memory. Implications for theory development and applications in wine education are discussed.

BACKGROUND: Insomnia is a prevalent condition with significant health, societal, and economic impacts. Cognitive behavioral therapy for insomnia (CBTI) is recommended as the first-line treatment. With limited accessibility to in-person-delivered CBTI (ipCBTI), electronically delivered eHealth CBTI (eCBTI), ranging from telephone- and videoconference-delivered interventions to fully automated web-based programs and mobile apps, has emerged as an alternative. However, the relative efficacy of eCBTI compared to ipCBTI has not been conclusively determined. OBJECTIVE: This study aims to test the comparability of eCBTI and ipCBTI through a systematic review and meta-analysis of equivalence based on randomized controlled trials directly comparing the 2 delivery formats. METHODS: A comprehensive search across multiple databases was conducted, leading to the identification and analysis of 15 unique randomized head-to-head comparisons of ipCBTI and eCBTI. Data on sleep and nonsleep outcomes were extracted and subjected to both conventional meta-analytical methods and equivalence testing based on predetermined equivalence margins derived from previously suggested minimal important differences. Supplementary Bayesian analyses were conducted to determine the strength of the available evidence. RESULTS: The meta-analysis included 15 studies with a total of 1083 participants. Conventional comparisons generally favored ipCBTI. However, the effect sizes were small, and the 2 delivery formats were statistically significantly equivalent (P<.05) for most sleep and nonsleep outcomes. Additional within-group analyses showed that both formats led to statistically significant improvements (P<.05) in insomnia severity; sleep quality; and secondary outcomes such as fatigue, anxiety, and depression. Heterogeneity analyses highlighted the role of treatment duration and dropout rates as potential moderators of the differences in treatment efficacy. CONCLUSIONS: eCBTI and ipCBTI were found to be statistically significantly equivalent for treating insomnia for most examined outcomes, indicating eCBTI as a clinically relevant alternative to ipCBTI. This supports the expansion of eCBTI as a viable option to increase accessibility to effective insomnia treatment. Nonetheless, further research is needed to address the limitations noted, including the high risk of bias in some studies and the potential impact of treatment duration and dropout rates on efficacy.

BACKGROUND: Considering the persistent nature and higher prevalence of insomnia in cancer patients and survivors compared with the general population, there is a need for effective management strategies. This systematic review and meta-analysis aimed to comprehensively evaluate the available evidence for the efficacy of pharmacological and nonpharmacological interventions for insomnia in adult cancer patients and survivors. METHODS: Following the PRISMA guidelines, we analyzed data from 61 randomized controlled trials involving 6528 participants. Interventions included pharmacological, physical, and psychological treatments, with a focus on insomnia severity and secondary sleep and non-sleep outcomes. Frequentist and Bayesian analytical strategies were employed for data synthesis and interpretation. RESULTS: Cognitive-Behavioral Therapy for Insomnia (CBT-I) emerged as the most efficacious intervention for reducing insomnia severity in cancer survivors and further demonstrated significant improvements in fatigue, depressive symptoms, and anxiety. CBT-I showed a large postintervention effect (g = 0.86; 95% confidence interval [CI] = 0.57 to 1.15) and a medium effect at follow-up (g = 0.55; 95% CI = 0.18 to 0.92). Other interventions such as bright white light therapy, sleep medication, melatonin, exercise, mind-body therapies, and mindfulness-based therapies showed benefits, but the evidence for their efficacy was less convincing compared with CBT-I. Brief Behavioral Therapy for Insomnia showed promise as a less burdensome alternative for patients in active cancer treatment. CONCLUSIONS: CBT-I is supported as a first-line treatment for insomnia in cancer survivors, with significant benefits observed across sleep and non-sleep outcomes. The findings also highlight the potential of less intensive alternatives. The research contributes valuable insights for clinical practice and underscores the need for further exploration into the complexities of sleep disturbances in cancer patients and survivors.

Sleep is important for brain health, having both a restorative function and playing an important role in cognitive functions, e.g., attention, memory, learning, and planning. This review finds that sleep disturbances are prevalent and associated with poorer cognitive functioning in neurodegenerative disorders such as Parkinson's disease and in people with non-neurodegenerative diseases such as cancer and mood disorders. Screening for and treating sleep disturbances are potential supplementary approaches to preventing and treating cognitive impairment.
