The Effect of Baseline Patient and Caregiver Mindfulness on Dementia Outcomes

Background: Mindfulness is the practice of awareness and living in the present moment without judgment. Mindfulness-based interventions may improve dementia-related outcomes. Before initiating interventions, it would be beneficial to measure baseline mindfulness to understand targets for therapy and its influence on dementia outcomes. Objective: This cross-sectional study examined patient and caregiver mindfulness with patient and caregiver rating scales and patient cognitive performance and determined whether dyadic pairing of mindfulness influences patient outcomes. Methods: Individuals (N = 291) underwent comprehensive evaluations, with baseline mindfulness assessed using the 15-item Applied Mindfulness Process Scale (AMPS). Correlation, regression, and mediation models tested relationships between patient and caregiver mindfulness and outcomes. Results: Patients had a mean AMPS score of 38.0±11.9 and caregivers had a mean AMPS score of 38.9±11.5. Patient mindfulness correlated with activities of daily living, behavior and mood, health-related quality of life, subjective cognitive complaints, and performance on episodic memory and attention tasks. Caregiver mindfulness correlated with preparedness, care confidence, depression, and better patient cognitive performance. Patients in dyads with higher mindfulness had better cognitive performance, less subjective complaints, and higher health-related quality of life (all p-values<0.001). Mindfulness effects on cognition were mediated by physical activity, social engagement, frailty, and vascular risk factors. Conclusion: Higher baseline mindfulness was associated with better patient and caregiver outcomes, particularly when both patients and caregivers had high baseline mindfulness. Understanding the baseline influence of mindfulness on the completion of rating scales and neuropsychological test performance can help develop targeted interventions to improve well-being in patients and their caregivers.

The difference between the pain self-perceptions of children with cerebral palsy and those of their caregivers

Introduction/Objective. Pain is often an under-recognized entity in children with cerebral palsy. The aim of this study was to determine whether there are differences in pain self-perception between children with cerebral palsy and their caregivers. Methods. This retrospective study included 70 children with cerebral palsy and 70 of their caregivers, treated at the Institute of Child and Youth Health Care of Vojvodina, Serbia. Pain intensity ratings on the Visual Analog Scale (VAS) provided by children and/or their caregivers were analyzed. Results. The research involved 70 children with cerebral palsy and the same number of their caregivers. While only 43 (61.4%) of these children were testable, all 70 caregivers participated. Pain was reported by 19 (44.2%) children and 42 (60%) caregivers, while 17 (39.5%) children suffered from musculoskeletal pain, which was noted by 39 (55.7%) caregivers. Average caregiver rating for musculoskeletal pain for children at Level V, I and III on the Gross Motor Function Classification System (GMFCS) was 6.20 ? 2.10, 2.67 ? 2.18, and 2.50 ? 2, respectively. Average self- and caregiver-reported VAS rating for headache/stomachache was 2.73 ? 1.86 and 2.35 ? 1.49, respectively (p > 0.05). Statistically significant differences were noted in the musculoskeletal pain VAS scores provided by the caregivers for children at different GMFCS levels (p < 0.01). Conclusion: Although no differences in pain perception between children with cerebral palsy and their caregivers have been established, in children with the most severe level of motor disability, caregivers report a statistically higher level of musculoskeletal pain.

Depression and anxiety symptoms in bereaved caregivers of patients with advanced cancer.

17 Background: Caregivers of patients with advanced cancer experience substantial caregiving burden and psychological distress during the illness course. However, data on depression and anxiety symptoms in bereaved caregivers and factors associated with their psychological distress are lacking. Methods: We conducted a secondary analysis of 168 caregivers enrolled in a randomized trial of early palliative care integrated with oncology care versus oncology care alone for patients newly-diagnosed with incurable lung and non-colorectal gastrointestinal cancers and their caregivers who completed bereavement assessments at 3 months after their loved one’s death. We used the Hospital Anxiety and Depression Scale (HADS) to assess patients’ and caregivers’ depression and anxiety symptoms at baseline within 8 weeks of diagnosis, and at 3-4 months after the patient’s death (for caregivers). We asked caregivers to rate patient’s physical and psychological distress in the last week of life on a 10-point scale. We used linear regression adjusting for randomization and cancer type to explore associations between patient and caregiver factors and bereaved caregivers’ depression and anxiety. Results: 30.4% (51/168) and 43.4% (73/168) of bereaved caregivers reported clinically significant depression and anxiety symptoms, respectively. Younger patient age (B = -0.06, P = 0.041), higher patient baseline anxiety (B = 0.28, P = 0.002), and caregiver rating of worse physical (B = 0.28, P = 0.035) and psychological (B = 0.41, P < 0.001) distress experienced by the patient at the end of life (EOL) were associated with worse depression symptoms in bereaved caregivers. Only caregiver factors, including age (B = -0.07, P = 0.004), female sex (B = 1.60, P = 0.024), and rating of worse psychological distress experienced by the patient at the EOL (B = 0.42, P < 0.001) were associated with worse bereaved caregivers’ anxiety symptoms. Conclusions: Bereaved caregivers of patients with advanced cancer experience substantial psychological distress which is associated with their perceptions of their loved one’s distress at the EOL. Interventions to optimize EOL care for patients and reduce bereaved caregivers’ psychological distress are needed.

Dietary long-chain omega-3 fatty acids are related to impulse control and anterior cingulate function in adolescents

Impulse control, an emergent function modulated by the prefrontal cortex (PFC), helps to dampen risky behaviors during adolescence. Influences on PFC maturation during this period may contribute to variations in impulse control. Availability of omega-3 fatty acids, an essential dietary nutrient integral to neuronal structure and function, may be one such influence. This study examined whether intake of energy-adjusted long-chain omega-3 fatty acids (eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA)) was related to variation in impulse control and PFC activity during performance of an inhibitory task in adolescents (n= 87; 51.7% female, mean age 13.3+1.1 years) enrolled in a longitudinal neuroimaging study. Intake of DHA+EPA was assessed using a food frequency questionnaire and adjusted for total energy intake. Inhibitory control was assessed using caregiver rating scale (BRIEF Inhibit subscale) and task performance (false alarm rate) on a Go/No-Go task performed during functional MRI. Reported intake of long-chain omega-3 was positively associated with caregiver ratings of adolescent ability to control impulses (p=0.017) and there was a trend for an association between intake and task-based impulse control (p=0.072). Furthermore, a regression of BOLD response within PFC during successful impulse control (Correct No-Go versus Incorrect NoGo) with energy-adjusted DHA+EPA intake revealed that adolescents reporting lower intakes display greater activation in the dorsal anterior cingulate, potentially suggestive of a possible lag in cortical development. The present results suggest that dietary omega-3 fatty acids are related to development of both impulse control and function of the dorsal anterior cingulate gyrus in normative adolescent development. Insufficiency of dietary omega-3 fatty acids during this developmental period may be a factor which hinders development of behavioral control.

Differential perceptions of quality of life (QoL) in community-dwelling persons with mild-to-moderate dementia

ABSTRACTBackground:Discordance between patient- and caregiver-reported quality of life (QoL) is well recognized. This study sought to (i) identify predictors of discrepancy between patient- and caregiver-rated QoL amongst community-dwelling persons with mild-to-moderate dementia, and (ii) differentiate between patients who systematically rate their QoL lower versus those who rate their QoL higher relative to their caregiver ratings.Methods:We recruited 165 patient–caregiver dyads with mild-to-moderate dementia. Quality of life in Alzheimer's disease (QoL-AD) scale was administered separately to patients and caregivers. Data on socio-demographics, interpersonal relationship, and disease-related characteristics (cognitive performance, mood, neuropsychiatric symptoms, functional ability, and caregiver burden) were collected. Patient–caregiver dyads were categorized based on whether patient-rated QoL was lower or higher than their respective caregiver ratings. Univariate analyses and multiple regression models were performed to identify predictors of dyadic rating discrepancy.Results:Mean patient-rated QoL was significantly higher than caregiver rating (mean difference: 3.8 ± 7.1, p < 0.001). Majority (111 (67.2%)) of patients had more positive self-perceived QoL (QoL-ADp (QoL-AD self rated by the patient) > QoL-ADc (QoL-AD proxy-rated by a caregiver)), compared with those (44 (26.7%)) with poorer self-perceived QoL (QoL-ADp < QoL-ADc). Patient's education level, depressive symptoms, and severity of neuropsychiatric symptoms predicted magnitude of discrepancy. Depression (OR = 1.17, 95% CI = 1.02–1.35) and being cared for by other relative (non-spouse/adult child; OR = 7.54, 95% CI = 1.07–53.03) predicted poorer self-perceived QoL.Conclusions:Dyadic rating discrepancy in QoL should draw the clinician's attention to patient depression and neuropsychiatric symptoms. Consideration should also be given to nature of patient–caregiver relationship when discordance between patient and caregiver assessments of QoL is observed.

Caregiver rating bias in mild cognitive impairment and mild Alzheimer's disease: impact of caregiver burden and depression on dyadic rating discrepancy across domains

ABSTRACTBackground: Caregivers of individuals with dementia are biased in their rating of mental health measures of the care receiver. This study examines caregiver burden and depression as predictors of this bias for mild cognitive impairment and mild Alzheimer's disease in different domains.Methods: The sample consisted of 202 persons: 60 with mild cognitive impairment, 41 with mild Alzheimer's disease, and 101 caregivers. Discrepancy scores were calculated by subtracting the mean caregiver score from the respective mean patient score on the following assessment instruments: the Geriatric Depression Scale, Apathy Evaluation Scale, Bayer-Activities of Daily Living Scale, and Quality of Life-AD scale. Caregiver burden and depression were assessed by the Zarit Burden Interview and the Center for Epidemiologic Studies Depression Scale.Results: Intraclass correlation coefficients were low for apathy (0.38), daily functioning (0.38), and quality of life (0.30) and moderate for depression (0.49). These domains showed negative rating discrepancies, which indicates caregiver rating bias for all four domains. Regression analyses revealed that caregiver burden significantly contributed to explaining these discrepancies in the domains apathy, daily functioning, and quality of life.Conclusion: Caregiver rating bias can be attributed to caregiver burden. When caregiver burden is present, data based on caregiver ratings should therefore be interpreted with caution.

Predictors of Discrepancies in Parkinson's Disease Patient and Caregiver Ratings of Apathy, Disinhibition, and Executive Dysfunction before and after Diagnosis

Parkinson's disease (PD) patient and caregiver reports of patient functioning are often used interchangeably in clinical and research settings; however, the consistency of these reports is largely unknown. This study aimed to investigate the consistency and predictors of discrepancy between self- and caregiver reports of patient apathy, disinhibition, and executive dysfunction. Fifty-one pairs of nondemented PD patients and their caregivers completed the Frontal Systems Behavior Scale (FrSBe). Patients were administered a neuropsychological battery, and mood and burden were assessed in a subset of caregivers. Patients and caregivers significantly differed in their ratings of all retrospective prediagnosis behaviors and current levels of disinhibition. Current levodopa equivalent dosages predicted patient-caregiver rating differences in prediagnosis and current apathy and current executive dysfunction, while patient motor function, cognition, and mood failed to predict any disparities in ratings. Caregiver burden and depression were associated with apathy rating discrepancies, while burden was associated with discrepancies in ratings of disinhibition. These results suggest that consistency of patient and caregiver behavioral ratings may vary depending on the behavior assessed; and underscore the importance of considering the reporter when using subjective measures, as discrepancies in behavioral reports may be influenced by specific patient and/or caregiver symptoms or factors.
