To date, no remediation treatment is available aimed at improving cognitive functioning in patients with older age bipolar disorder (OABD). Our pilot intervention (Brain train) included cognitive training, physical exercise, and social encounter with peers for OABD and was positively evaluated by the participants. However, its feasibility was limited as few patients fulfilled the inclusion criteria of cognitive and social impairment and retaining the physical ability to walk for a minimum of 30 min. OABD patients with cognitive impairment are a vulnerable group for which it is most challenging to design interventions aimed at improving daily functioning.

Introduction: Previous studies suggest an association between poor mastication and cognitive impairment. The role of chewing efficiency and dentition in this relation is unclear. The aim was to examine global cognitive functioning and dentition as predictors for chewing efficiency, in older people with mild cognitive impairment (MCI) or dementia. Methods: In this observational cross-sectional study, 136 people with MCI or dementia were included. The chewing efficiency was assessed with a two-colored chewing gum and analyzed with the Chewing Efficiency Analysis software. The level of global cognitive functioning was measured with the Mini Mental State Examination (MMSE) by trained clinical staff. An oral examination was performed by a dentist and included the number of present teeth, the number of occluding pairs, and the presence of prostheses. Age, gender, and educational years were derived from the medical records. Univariate and multivariate backward stepwise linear regression analyses were used to evaluate global cognitive functioning and dentition as predictors for chewing efficiency. Results: The mean age of the participants was 82.1 (SD 5.8) years, and 74 (54.4%) were female. The participants had a median MMSE score of 22.4 (IQR 18.0–26.0) and a median Chewing Efficiency Analysis score of 0.46 (IQR 0.14–0.59). The median number of teeth was 13.0 (IQR 0.0–23.0), and the median number of occluding pairs was 0.0 (IQR 0.0–7.0). Sixty-four (47.4%) of the participants wore full prosthesis in the upper jaw. In univariate linear regression analyses, predictive factors for the Chewing Efficiency Analysis score were age, MMSE score, full prosthesis in the upper jaw, number of present teeth, and number of occluding pairs. In the multivariate model, full prosthesis in the upper jaw and number of occluding pairs were significant predictors for the Chewing Efficiency Analysis score. Participants with full prosthesis in the upper jaw had a lower Chewing Efficiency Analysis score than participants with natural dentition in the upper jaw. Conclusion: Better mastication is associated with a higher number of occluding pairs. Full prosthesis in the upper jaw is related to a lower chewing efficiency. Global cognitive functioning is not associated with mastication in older people with MCI or mild-to-moderate dementia. This might be explained by sufficient capacity for compensation of reduced mastication in this group.

Background: The role of cognitive reserve (CR) to explain individual differences in cognitive functioning is unclear in memory clinic patients. Objective: To examine the cross-sectional effect of CR on cognition in relation to levels of neurodegeneration in a large elderly single-center memory clinic population. Methods: We included patients with subjective cognitive impairment (SCI, n = 481), mild cognitive impairment (MCI, n = 628) or Alzheimer's disease (AD, n = 1,099). Education was used as proxy for CR and visually rated medial temporal lobe atrophy (MTA) on CT was used as parameter of neurodegeneration. Relations between CR, cognition, and MTA were analyzed with multiple linear regression adjusted for age, sex, and cerebral atrophy. In addition, we examined if education affects the relation between MTA and cognition using an interaction variable. Results: Education was significantly related to all measures of cognition including subtests with an explained variance of education as a determinant of cognition of 11%. More highly educated patients had more advanced levels of MTA at the same level of cognition. All these results were stronger or only present in demented compared to non-demented patients but appeared no longer significant in those with lowest overall cognition. The interaction effect was significant indicating that with more advanced MTA, less cognitive decline was shown in higher educated patients. Conclusion: Education is a very strong determinant of cognition in an elderly memory clinic population. The positive effect of education was stronger in demented than in non-demented patients but disappeared in those with the lowest cognitive scores indicating a 'window of CR benefit'.

BACKGROUND: Despite the evidence that disrupted sleep-wake cycles are associated with an exacerbation of behavioural disturbances and an acceleration of the disease progression in dementia, the effect of sensory stimulation for improving sleep quality and rest-activity rhythm is unclear. The aim of the current meta-analysis is to give an overview of the effectiveness of sensory stimulation interventions on reduction and prevention of sleep disturbances in nursing homes residents with dementia. METHOD: A systematic literature search and meta-analysis were performed on December 3, 2019. Twenty-seven studies examining the effects of a sensory stimulation intervention on rest-activity rhythm and/or nocturnal restlessness in nursing home residents with dementia were included. Outcomes were measured with Actiwatches and/or standardized observation scales. Extensive subgroup meta-analyses were performed to adjust for varying characteristics of included studies. RESULT: Uni-sensory stimulation including tactile and visual stimulation (i.e. light therapy, massage, acupuncture, animal-assisted interventions) seemed effective for improving sleep quality and strengthen the rest-activity rhythm (Hedges g=.47, p ≤ .01, Figure 1). More specifically, visual and tactile stimulation with a minimum of 30 minutes/day for two weeks have effectively reduced the duration of nocturnal awakenings (g=-.29, p≤.05), sleep onset latency (g=-.25, p≤.05), and nocturnal behaviour disturbances (g=-.57, p≤.01), and have improved nocturnal sleep duration (g = .38, p ≤ .01), and sleep efficiency (g=.48, p≤.01). The heterogeneity within the majority of outcomes varied between medium and large. The majority of studies were of poor quality (59%, Figure 2). Dementia type and severity, gender, treatment duration and intensity (light levels in lux values) were not related to the effectiveness of sensory stimulation in all outcomes. CONCLUSION: Although the methodological quality of the studies was limited, we found indications that sleep quality and nocturnal restlessness in nursing home residents with dementia may benefit from sensory stimulation. Recommended is to use a sensory stimulating environment in nursing homes which may prevent or improve sleep disturbances, and therefore can contribute to higher quality of life of their patients. Future research should conduct RCTs, while using comparable interventions, measuring instruments and procure, so the quality of dementia can be further improved.

Research on the association between physical inactivity and cognitive decline and dementia is dominated by studies with short-term follow-up, that might be biased by reverse causality.Investigate the long-term association between physical activity, cognition, and the rate of age-associated cognitive decline.We investigated the association between late-life physical activity and executive functioning and rate of decline of executive abilities during follow-up of up to 16 years, in 3553 participants of the prospective Rotterdam Study cohort. Measurement took place in 1997-1999, 2002-2004, 2009-2011, and 2014-2015.At baseline (age ± 72 years), higher levels of physical activity were associated with higher levels of executive functioning (adjusted mean difference = 0.03, 95% CI: 0.00 ; 0.06, p = 0.03). This difference remained intact up to 16 years of follow-up. The level of physical activity at baseline was unrelated to the rate of decline of executive abilities over time, in the whole group (adjusted mean difference in changeHigher levels of physical activity in late adulthood are related to higher levels of executive functioning, up to 16 years of follow-up. Accelerated decline of executive abilities observed in those with the ApoE-ε4 allele might be mitigated by higher levels of physical activity.

The severe consequences of the present Corona Virus Disease 2019 COVID-19 pandemic seem to be closely related to an already ongoing (‘first’) pandemic, directly associated with a sedentary lifestyle. It seems evident that the prognosis after infection is substantially worse for individuals suffering from, for example, (visceral) obesity, cardiovascular disease, and diabetes type 2. Consequently, it may be considered highly relevant to gain insight into the potential beneficial effects of exercise interventions to strengthen the immune system, particularly in high-risk populations. For this reason, the exercise protocols that are suggested to strengthen the immune system, which can be executed by all ages and almost all physical conditions, were reviewed and evaluated. Previously published protocols range from interrupting prolonged sitting, to regular low-to-moderate exercise activities, to high intensity, typically interval, sports formats. Reported positive effects on immune functioning appear to be induced either directly or via beneficial metabolic and/or psychological effects and become measurable after 3 weeks to 3 months. Based in these findings, it appeared possible to design an optimal exercise protocol to maximize effects on immune functioning that should be executable for all, even under restricted (‘lockdown’) circumstances.

Background: The association between pain and dementia is complicated and may depend on underlying brain pathology. It was hypothesized that both medial temporal atrophy (MTA) and global cortical atrophy (GCA) predicted no/mild pain, while white matter hyperintensities (WMH) predicted moderate/severe pain. Objectives: To study the association between pain intensity and measures of brain pathology, more specifically MTA, GCA, and WMH. Methods: In total, 115 consecutive patients visiting an outpatient memory clinic were included. In total, diagnoses included dementia (N=70), mild cognitive impairment (N=30), and subjective cognitive impairment (N=15). Without administering stimuli, pain intensity was assessed with the Brief Pain Inventory. MTA, GCA, and WMH were measured with a MRI visual rating scale. Logistic regression analyses to examine the relationship between WMH, MTA, GCA, and self-reported pain intensity (no/mild pain versus moderate/severe pain) were adjusted for confounders. Results: Mean age of the patients was 81 years (IQR: 78-85, 53% female). Moderate/severe pain was reported by 23.5% and associated with greater WMH (OR =3.34, 95% CI =1.01-10.97, p=0.047), but not MTA or GCA. Conclusions: In contrast to the present results, earlier studies have reported either a positive or negative relationship between pain and brain volume. It is suggested that the presence of dementia may explain the absence of a relationship between pain and brain volume. WMH is positively related with pain in an older memory outpatient population. Considering the small sample size, our findings should be interpreted with caution. Hence, our conclusions are preliminary findings, warranting future replication.

Background: Nursing home residents with dementia show a rapid decline in their ability to perform activities of daily living. This decline is linked to a greater care dependency, which is associated with a reduced quality of life. Care dependency is influenced by multiple predictors, yet current research often focuses on the contribution of a single or a small number of predictors of care dependency. Objectives: To examine the contribution of multiple predictors in predicting care dependency. Design: The present study analyzed baseline data from a 6-month double-parallel randomized controlled trial which examined the effect of three physical activity interventions on multiple outcomes. Setting: This study was conducted in eleven nursing homes in Bergen op Zoom, the Netherlands. Participants: In total, 85 nursing home residents with moderate to severe dementia were included in the study, of which 75 were included for analysis. Methods: Predictors considered were cognitive, physical, neuropsychiatric, demographic, and disease related factors. The outcome measure care dependency was assessed with the Care Dependency Scale and the Erlangen Test of Activities of Daily Living. Linear multilevel regression analyses were used to identify the most important predictors of care dependency. Results: Apathy, physical endurance, number of comorbidities, and global cognition were significant predictors of care dependency. The model explained 66% of the variance in care dependency. Global cognition was a significant predictor of ability to perform activities of daily living and explained 60% percent of its variance. Conclusion: The present study shows that multiple predictors (i.e., apathy, cognitive and physical abilities, and disease-related factors) contribute to predicting care dependency. Future research could focus on the effectiveness of multifactorial interventions to maintain the highest possible level of independence in nursing home residents with dementia.

BACKGROUND: The number of people with dementia and natural dentition is growing. As dementia progresses, the degree of self-care decreases and the risk of oral health problems and orofacial pain increases.OBJECTIVES: To examine and compare the presence of orofacial pain and its potential causes in older people with Mild Cognitive Impairment (MCI) or dementia.METHODS: In this cross-sectional observational study, the presence of orofacial pain and its potential causes was studied in 348 participants with MCI or dementia with all levels of cognitive impairment in two outpatient memory clinics and ten nursing homes.RESULTS: Orofacial pain was reported by 25.7% of the 179 participants who were considered to present a reliable pain self-report (Mini-Mental State Examination score ≥14 points), while it could not be determined in people with more severe cognitive impairment. The oral health examination of the 348 participants indicated that potential painful conditions, such as coronal caries, root caries, tooth root remnants or ulcers were present in 50.3%. There was a significant correlation between the level of cognitive impairment and the number of teeth, r = 0.185, P = 0.003, teeth with coronal caries, r = -0.238, P < 0.001, and the number of tooth root remnants, r = -0.229, P = 0.004, after adjusting for age.CONCLUSIONS: This study indicated that orofacial pain and its potential causes were frequently present in participants with MCI or dementia. Therefore, a regular oral examination by (oral) healthcare providers in people with MCI or dementia remains imperative, even if no pain is reported.

The objective of this cross-sectional study was to investigate if Traumatic Brain Injury (TBI) is related to decision-making deficits as well as to heightened levels of (reactive) aggression and criminal behavior in a group of Dutch male prisoners. Characteristics of aggression were assessed using three self-report questionnaires as well as systematic staff observations, complemented with data from criminal records. A semi-structured interview was conducted to rate lifetime prevalence of TBI and the Iowa Gambling Task (IGT) was completed to assess risky decision-making. Out of the total of 133 participants, 74 (55.6%) reported having sustained one or more incidents with potential TBI. Statistical comparisons between offenders with and without TBI indicated that the offenders with TBI reported significantly higher levels of (reactive) aggression on two out of three questionnaires than offenders without TBI (p-values ranging from 0.003 to 0.008), but no significant differences were found on staff observations of aggression and on the IGT. The higher conviction rates in offenders with TBI compared to the non-TBI group showed a trend. The confirmed relationship between TBI and higher aggressive tendencies is especially relevant for forensic populations due to the high prevalence rates of TBI in offenders. How this relates to specific cognitive processes remains unclear. The lack of a statistical difference between offenders with and without TBI on the IGT is in contrast with literature in non-offender samples, but seems to be in line with other studies in forensic populations.

Research on the association between non-motor symptoms (NMS) of Parkinson's discasc (PD) and patients' quality of life (QoL) has given insight into the burden of NMS. Most studies investigate NMS by assessing the contribution of individual symptoms to QoL. However, symptoms could also have an interactive relationship, which might not be fully taken into account when only studying these individual contributions. Recently, a network approach has been developed that treats symptoms as nodes and associations between symptoms as edges in a network, providing the opportunity to investigate the dimensional spectrum of NMS. In the current cross-sectional study, we investigated NMS with both approaches: first, we assessed individual contributions of NMS to QoL. Second, we aimed to assess NMS using a network approach. Seventy PD patients completed questionnaires on NMS and QoL. Our primary analysis shows that the domains Mood and Pain are significant contributors to QoL. Our secondary network analysis suggests that Mood and Sleep play central roles in the NMS-network, and that Mood and Cognition are strongly related. Because of power issues, the generalizability of our explorative results is limited. However, complementary information from the network analysis does suggest that focusing on sleep problems might help both mood and pain symptoms, which negatively affect QoL. Investigating symptoms not only as individual and independent entities but rather as part of a connected network could show how treating one symptom affects other symptoms.

Introduction: It is known that music may enhance emotional well-being which may have a positive effect on sleep. The goal of the present study was to examine whether a specific type of music, rapping and singing (Rap & Sing Music Therapy (Rap&SingMT)) could serve as a motivating engagement strategy to improve sleep in adolescents. Methods: Fifty-two adolescents received Rap&SingMT, 45 min, once a week, during four months in a group school setting. Twenty-three adolescents in the control group received a program of various mental activities–but no music. Actigraphy assessed six sleep variables: sleep time, sleep efficiency, sleep episodes, snooze time, onset latency and wake percentage. Sleep assessments took place at baseline and after four months (post-testing). Results: A repeated-measures multivariate analysis of variance failed to demonstrate a significant effect of Rap&SingMT on “overall” sleep. However, a decline in total sleep time over a period of four months was less in the Rap&SingMT group than in the control group. Discussion: Despite the fact that the participants did not suffer from sleep disturbances, a seasonal change over the experimental period of four months appeared to have less impact on total sleep time in the Rap&SingMT group. These findings will be addressed in more detail.

Background As several COVID-19 vaccines are rolled-out globally, it has become important to develop an effective strategy for vaccine acceptance, especially in high-risk groups, such as elderly. Vaccine misconception was declared by WHO as one of the top 10 health issues in 2019. Here we test the effectiveness of applying debunking to combat vaccine misinformation, and reduce vaccine hesitancy. Methods Participants were recruited via a daily news show on Dutch Television, targeted to elderly viewers. The study was conducted in 980 elderly citizens during the October 2020 National Influenza Vaccination Campaign. Borrowing from the recent literature in behavioural science and psychology we conducted a two-arm randomized blinded parallel study, in which participants were allocated to exposure to a video containing social norms, vaccine information plus debunking of vaccination myths (intervention group, n = 505) or a video only containing vaccine information plus social norm (control group, n = 475). Participants who viewed either of the video's and completed both a pre- and post-intervention survey on vaccination trust and knowledge, were included in the analysis. The main outcomes of this study were improvement on vaccine knowledge and awareness. Findings Participants were recruited from the 13th of October 2020 till the 16th of October 2020 and could immediately participate in the pre-intervention survey. Subsequently, eligible participants were randomly assigned to an interventional video and the follow-up survey, distributed through email on the 18th of October 2020, and available for participation till the 24th of October 2020. We found that exposure to the video with addition of debunking strategies on top of social norm modelling and information resulted in substantially stronger rejection of vaccination misconceptions, including the belief that: (1) vaccinations can cause Autism Spectrum Disorders; (2) vaccinations weaken the immune system; (3) influenza vaccination would hamper the COVID-19 vaccine efficacy. Additionally, we observed that exposure to debunking in the intervention resulted in enhanced trust in government. Interpretation Utilizing debunking in media campaigns on top of vaccine information and social norm modeling is an effective means to combat misinformation and distrust associated with vaccination in elderly, and could help maximize grounds for the acceptance of vaccines, including the COVID-19 vaccines.

Background: Brain-derived neurotropic factor (BDNF) plays a vital role in neuronal survival and plasticity and facilitates long-term potentiation, essential for memory. Alterations in BDNF signaling have been associated with cognitive impairment, dementia, and Alzheimer’s disease. Although peripheral BDNF levels are reduced in dementia patients, it is unclear whether changes in BDNF levels precede or follow dementia onset. Objective: In the present study, we examined the association between BDNF plasma levels and dementia risk over a follow-up period of up to 16 years. Methods: Plasma BDNF levels were assessed in 758 participants of the Rotterdam Study. Dementia was assessed from baseline (1997–1999) to follow-up until January 2016. Associations of plasma BDNF and incident dementia were assessed with Cox proportional hazards models, adjusted for age and sex. Associations between plasma BDNF and lifestyle and metabolic factors are investigated using linear regression. Results: During a follow up of 3,286 person-years, 131 participants developed dementia, of whom 104 had Alzheimer’s disease. We did not find an association between plasma BDNF and risk of dementia (adjusted hazard ratio 0.99; 95%CI 0.84–1.16). BDNF levels were positively associated with age (B = 0.003, SD = 0.001, p = 0.002), smoking (B = 0.08, SE = 0.01, p =

Contains fulltext : 227192.pdf (Publisher’s version ) (Open Access) Cognitive reserve (CR) is known to reduce or even protect against the negative effects of aging on cognitive functioning. Nonetheless, little is known about how CR influences the relationship between different cognitive abilities and age in the old-old. The goal of the present study was, therefore, to test the hypothesis whether, in the old-old, CR still modifies the relationship between age and cognitive functioning. Eighty-three adults (aged 71-94) without mild cognitive impairment or dementia residing in residential care facilities completed a detailed neuropsychological test battery. CR was estimated using a combination of educational attainment and an estimation of verbal intelligence. Moderation analyses revealed a significant effect for fluency and a trend for flexibility, showing that the negative relationship between age and cognitive performance is reduced as the level of CR increases. These results demonstrate that CR still influences the relationship between age and executive functions in adults of advanced age. 6 p.

Background Understanding if and how pain influences activities of daily living (ADL) in dementia is essential to improving pain management and ADL functioning. This study examined the relationship between the course of pain and change in ADL functioning, both generally and regarding specific ADL functions. Methods Participants were Dutch nursing home residents (n = 229) with advanced dementia. ADL functioning was assessed with the Katz ADL scale, and pain with the Dutch version of the Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC-D). Changes of PACSLAC-D and Katz ADL scores were computed based on the difference in scores between baseline, 3-month and 6-month follow-up. Multivariate linear regression models were used to assess the relationships between change in pain score, change in total ADL score and specific ADL item scores during follow-up. Results At baseline, residents had a median ADL score of 18 (interquartile range 13–22, range 6–24) and 48% of the residents were in pain (PACSLAC-D ≥ 4). Residents with pain were more ADL dependent than residents without pain. A change in pain score within the first 3 months was a significant predictor for a decline in ADL functioning over the 6-month follow-up (B = 0.10, SE = 0.05, P = 0.045), and specifically, a decline on the items ‘transferring’ over the 6-month follow-up and ‘feeding’ during the first 3 months of follow-up. Conclusions Pain is associated with ADL functioning cross-sectionally, and a change in pain score predicts a decline in ADL functioning, independent of dementia severity. Awareness of (changes in) ADL activities is clearly important and might result in both improved recognition of pain and improved pain management.

Importance: In the absence of a vaccine and therapeutic agent, personal hygiene and physical distancing are essential measures to contain the coronavirus disease 2019 pandemic. Objective: To determine whether a social media campaign, targeted at the gaps in behavior on personal hygiene and physical distancing and distributed nationwide via digital news media, may be an effective method to improve behavior and help to inhibit person-to-person transmission of severe acute respiratory syndrome coronavirus 2. Design, Setting, and Participants: This survey study was designed to uncover self-reported gaps in behavior regarding personal hygiene and physical distancing in the Netherlands. A diagnostic survey was distributed by a large national newspaper (De Telegraaf) and a popular social influencer (Govert Sweep) on March 17, 2020, and was completed by 16 072 participants. Analysis of these outcomes showed that coughing and sneezing in the elbow was done well, but that handwashing, face touching, and physical distancing showed serious gaps compared with advised behavior. This diagnostic information was used to design infographics and a video targeted at repairing these gaps in behavior. The video and infographics were distributed on a national level on March 21, 2020, followed by a postcampaign survey to measure the results on March 24, 2020. Data analysis was performed from March to April 2020. Exposure: Exposed participants were those who viewed the infographics and/or video. Main Outcomes and Measures: Improvement on the extent of handwashing in all areas, handwashing duration of 20 seconds or longer, awareness on face touching, and physical distancing were measured according to responses on the postcampaign survey. Results: A total of 17 189 participants (mean [SD] age, 47.61 [13.57] years; 9100 women [52.9%]) responded to the postcampaign survey. The news article in De Telegraaf was read more than 2 million times, and the influencer video was watched more than 80 000 times. Cross-sectional analysis of the postcampaign survey using logistic regression correcting for age, gender, and educational level showed that exposure to the video plus infographics (827 participants) (adjusted odds ratio [OR], 2.14; 95% CI, 1.83-2.50; P

Background Potential moderators such as exercise intensity or apolipoprotein-E4 (ApoE4) carriership may determine the magnitude of exercise effects on physical and cognitive functions in patients with dementia (PwD). We determined the effects of a 24-week aerobic and strength training program with a low- and high-intensity phase on physical and cognitive function. Methods In an assessor-blinded randomized trial, 91 PwD (all-cause dementia, recruited from daycare and residential care facilities, age 82.3 ± 7.0 years, 59 women, Mini-Mental State Examination 20.2 ± 4.4) were allocated to the exercise or control group. In the exercise group, PwD participated in a walking and lower limb strength training program with 12 weeks low- and 12 weeks high-intensity training offered three times/week. Attention-matched control participants performed flexibility exercises and recreational activities. We assessed adherence, compliance, and exercise intensity for each session. We assessed physical (endurance, gait speed, mobility, balance, leg strength) and cognitive (verbal memory, visual memory, executive function, inhibitory control, psychomotor speed) functions with performance-based tests at baseline and after 6, 12, 18, 24, and 36 weeks (follow-up). ApoE4 carriership was determined post-intervention. Results Sixty-nine PwD were analyzed. Their mean attendance was ~ 60% during the study period. There were no significant effects of the exercise vs. control intervention on endurance, mobility, balance, and leg strength in favor of the exercise group (Cohen’s d = 0.13–0.18). Gait speed significantly improved with ~ 0.05 m/s after the high-intensity phase for exercise participants (Cohen’s d = 0.41) but declined at follow-up. There were no significant effects of the exercise vs. control intervention on any of the cognitive measures (Cohen’s d ~ − 0.04). ApoE4 carriership did not significantly moderate exercise effects on physical or cognitive function. Conclusions Exercise was superior to control activities for gait speed in our sample of PwD. However, the training effect provided no protection for mobility loss after detraining (follow-up). There were no beneficial effects of the exercise vs. control group on cognitive function. Exercise intensity moderated the effects of exercise on gait speed. ApoE4 carriership moderated the effect of exercise on global cognition only (trend level).

BackgroundPrevious literature has shown a putative relationship between playing a musical instrument and a benefit in various cognitive domains. However, to date it still remains unknown whether the exposure to a musically-enriched environment instead of playing an instrument yourself might also increase cognitive domains such as language, mathematics or executive sub-functions such as for example planning or working memory in primary school children.DesignCross-sectionalMethodExposure to a musically-enriched environment like listening to music at home, during play or when attending concerts was assessed using a comprehensive intake questionnaire administered to a sample of 176 primary school children. Furthermore, participants completed the verbal intelligence section of the Wechsler Intelligence Scale (WISC III), performed executive sub-function tasks such as planning (Tower of London), working memory (Klingberg Matrix backward span) and inhibition (Go/no-Go task), and a short-term memory task (Klingberg Matrix forward span).ResultsLinear and multiple regression analyses showed no significant relationship between exposure to a musically-enriched environment, executive sub-functions (planning, inhibition and working memory), and short-term memory. The relationship between an enriched musical environment and verbal IQ has revealed trends.DiscussionExperiencing a musically enriched environment does not serve as predictor for higher performance on executive sub-functions, however, can influence verbal IQ.

Pain is an important non-motor symptom in Parkinson’s disease (PD), but its underlying pathophysiological mechanisms are still unclear. Research has shown that functional connectivity during the resting-state may be involved in persistent pain in PD. In the present cross-sectional study, 24 PD patients (both during on and off medication phase) and 27 controls participated. We assessed pain with the colored analogue scale and the McGill pain questionnaire. We examined a possible pathophysiological mechanism with resting-state fMRI using functional network topology, i.e., the architecture of functional connections. We took betweenness centrality (BC) to assess hubness, and global efficiency (GE) to assess integration of the network. We aimed to (1) assess the differences between PD patients and controls with respect to pain and resting-state network topology, and (2) investigate how resting-state network topology (BC and GE) is associated with clinical pain in both PD patients and controls. Results show that PD patients experienced more pain than controls. GE of the whole brain was higher in PD patients (on as well as off medication) compared to healthy controls. GE of the specialized pain network was also higher in PD patients compared to controls, but only when patients were on medication. BC of the pain network was lower in PD patients off medication compared to controls. We found a positive association between pain and GE of the pain network in PD patients off medication. For healthy controls, a negative association was found between pain and GE of the pain network, and also between pain and BC of the pain network. Our results suggest that functional network topology differs between PD patients and healthy controls, and that this topology can be used to investigate the underlying neural mechanisms of pain symptoms in PD.

Marinda Henskens,1 Ilse M Nauta,2 Katja T Drost,3 Erik JA Scherder1 1Department of Clinical Neuropsychology, Vrije Universiteit Amsterdam, Amsterdam, the Netherlands; 2Department of Neurology, MS Center Amsterdam, Vrije Universiteit Medical Center, Amsterdam, the Netherlands; 3tanteLouise, Bergen op Zoom, the Netherlands Background: Nursing home (NH) residents with dementia experience a reduced quality of life (QoL), in part, due to a dependence in performing activities of daily living (ADL). Stimulating movement is associated with improvements in ADL performance. Therefore, movement stimulating interventions, such as ADL training and exercise, focus on optimizing ADL performance to improve QoL. This study aimed to evaluate the effect of three movement stimulating interventions on QoL and ADL performance in NH residents with dementia. Methods: In this 6-month double parallel randomized controlled trial, the effects of ADL training, a multicomponent aerobic and strength exercise training, and a combined ADL and exercise training were analyzed in 87 NH residents with dementia. The Global Deterioration Scale was used to classify the severity of dementia. Participants were screened at baseline using the 6 minute walk test and Mini-Mental State Examination. The Qualidem, and the Care Dependency Scale and Erlangen ADL test were evaluated at baseline, and after 3 and 6 months to measure QoL and ADL, respectively. Multilevel analyses were adjusted for baseline performance, age, and gender. Results: A 6-month ADL training positively affected overall QoL (p= 0.004) and multiple aspects of QoL, including care relationship (p = 0.004), positive self-image (p= 0.002), and feeling at home (p= 0.001), compared to care-as-usual. No benefits were observed of exercise on QoL. No benefits were observed of a combined ADL and exercise intervention on QoL. No effects were found of the three movement interventions on ADL performance. Conclusion: The results indicate that ADL training can improve QoL. The results contribute to the limited knowledge regarding the effect of movement stimulation on resident outcomes. Further large-scale studies are recommended.

Rogier Scherder,1 Neeltje Kant,2 Evelien T Wolf,3 Bas Pijnenburg,4 Erik JA Scherder3 1Department of Orthopedics, Westfries Gasthuis, Hoorn, 2Department of Neuropsychology, Reade, Amsterdam, 3Department of Clinical Neuropsychology, Vrije Universiteit, Amsterdam, 4Acibadem International Medical Center, Amsterdam, the Netherlands Background: It has been observed that patients with multiple sclerosis (MS), who have psychiatric and physical comorbidities such as depression and COPD, have an increased risk of experiencing more pain. In this study, we have distinguished between pain intensity and pain affect, as the latter, particularly, requires treatment. Furthermore, while pain and comorbidities have been assessed using questionnaires, this is possibly a less reliable method for those who are cognitively vulnerable. Objective: The aim of this study was to determine whether psychiatric and physical comorbidities can predict pain intensity and pain affect in MS patients, susceptible to cognitive impairment.Methods: Ninety-four patients with MS and 80 control participants participated in this cross-sectional study. Besides depression and anxiety, 47 additional comorbidities were extracted from patients’ medical records. Depression and anxiety were assessed using the Beck Depression Inventory and the Symptom Check List-90. Pain was assessed using the Number of Words Chosen Affective, Coloured Analog Scale, and the Faces Pain Scale. Cognitive functions, for example, memory and executive functions, were assessed using several neuropsychological tests.Results: The main findings indicate that psychiatric comorbidities (depression and anxiety) predict both pain intensity and pain affect and that total physical comorbidity predicts only pain affect in MS patients, susceptible to cognitive impairment.Conclusion: Both psychiatric and physical comorbidities predict pain affect. All three clinical outcomes enhance MS patients’ suffering. Keywords: multiple sclerosis, pain, comorbidities, mood, cognition

Objectives: The aim of this study was to examine and compare the oral function of older people with mild cognitive impairment (MCI) or dementia. Methods: This cross-sectional observational study included participants with MCI or dementia aged 60 years or older. Global cognitive functioning was evaluated with the Mini Mental State Examination (MMSE) and the oral function was evaluated with subjective and objective assessments, including the perceived quality of chewing and swallowing, the function of the prostheses, the number of occluding pairs (OP), the degree of tooth wear and the active and passive maximum mouth opening. Results: The quality of chewing and swallowing was perceived as good in, respectively, 86.0% and 90.9% of the participants. Full or partial prostheses were worn by 63.8% of the participants, and the retention was good in 58.4% of the upper and 50.0% of the lower prostheses. Participants with MCI had a median of 3.0 (Inter Quartile Range [IQR] 0.0-7.5) occluding pairs, while participants with dementia had a median of 0.0 (IQR 0.0-1.0) occluding pairs, U = 3838.50, P

Objective. To examine whether hypoesthesia and chronic pain are related in patients with MS. Methods. Sixty-seven MS patients with pain and 80 persons without MS were included. Sensory functioning was tested by bedside neurological examination. Touch, joint position (dorsal column-medial lemniscus pathway), temperature sense, and pain (spinothalamic tract) were tested. Pain intensity was measured by the Colored Analogue Scale (CAS Intensity) and the Faces Pain Scale (FPS); pain affect was also measured by CAS Affect and Number of Words Chosen-Affective (NWC-A). Mood was assessed with the SCL-90 anxiety and depression subscales and the Beck Depression Inventory (BDI). Results. A significant negative relationship was found between pain intensity and the function of the dorsal column-medial lemniscal pathway, but not with the spinothalamic tract. Conclusion. In addition to the already known relation between hyperesthesia and pain, hypoesthesia for touch and joint position also seems to be related to chronic pain in MS patients.

Background The number of older people with dementia and a natural dentition is growing. Recently, a systematic review concerning the oral health of older people with dementia with the focus on diseases of oral hard tissues was published. Objective To provide a comprehensive literature overview following a systematic approach of the level of oral hygiene and oral health status in older people with dementia with focus on oral soft tissues. Methods A literature search was conducted in the databases PubMed, CINAHL, and the Cochrane Library. The following search terms were used: dementia and oral health or stomatognathic disease. A critical appraisal of the included studies was performed with the Newcastle-Ottawa scale (NOS) and Delphi list. Results The searches yielded 549 unique articles, of which 36 were included for critical appraisal and data extraction. The included studies suggest that older people with dementia had high scores for gingival bleeding, periodontitis, plaque, and assistance for oral care. In addition, candidiasis, stomatitis, and reduced salivary flow were frequently present in older people with dementia. Conclusions The studies included in the current systematic review suggest that older people with dementia have high levels of plaque and many oral health problems related to oral soft tissues, such as gingival bleeding, periodontal pockets, stomatitis, mucosal lesions, and reduced salivary flow. Scientific rationale for study With the aging of the population, a higher prevalence of dementia and an increase in oral health problems can be expected. It is of interest to have an overview of the prevalence of oral problems in people with dementia. Principal findings Older people with dementia have multiple oral health problems related to oral soft tissues, such as gingival bleeding, periodontal pockets, mucosal lesions, and reduced salivary flow. Practical implications The oral health and hygiene of older people with dementia is not sufficient and could be improved with oral care education of formal and informal caregivers and regular professional dental care to people with dementia.

Contains fulltext : 191183.pdf (Publisher’s version ) (Closed access) Objective: To assess the pain prevalence, pain intensity, and pain medication use in older patients with a diagnosed subtype of dementia, mild cognitive impairment (MCI), or subjective cognitive impairment (SCI). Design: Cross-sectional. Setting: Outpatient memory clinics. Subjects: In total, 759 patients with Alzheimer's disease (AD), vascular dementia, mixed AD and vascular pathology (MD), frontotemporal dementia, dementia with Lewy Bodies, MCI, or SCI. Methods: Self-reported presence and intensity of pain, prescribed medication, and related descriptive variables were given for each group. To compare groups on prevalence of pain, logistic regression analyses were adjusted for age, gender, and mood. Differences in pain intensity were tested using a Kruskall-Wallis test, and differences in analgesic use with chi-square analyses. Results: Pain prevalence ranged from 34% in MD to 50% in SCI. AD (odds ratio [OR] = 0.56, 95% confidence interval [CI] = 0.34-0.93) and MD (OR = 0.45, CI = 0.20-0.98) patients were less likely to report pain than SCI patients. The self-reported pain intensity did not differ between groups. In total, 62.5% of patients did not use any analgesic medication despite being in pain, which did not differ significantly between groups. Conclusion: Outpatient memory clinic patients with mild to moderate AD and MD are less likely to report pain than patients with SCI. No difference in self-reported pain intensity was present. The high percentage of patients with and without dementia who do not use analgesics when in pain raises the question of whether pain treatment is adequate in older patients. 8 p.

Purpose The Drug Burden Index (DBI) is a tool to quantify the anticholinergic and sedative load of drugs. Establishing functional correlates of the DBI could optimize drug prescribing in patients with dementia. In this cross-sectional study, we determined the relationship between DBI and cognitive and physical functions in a sample of patients with dementia. Methods Using performance-based tests, we measured physical and cognitive functions in 140 nursing home patients aged over 70 with all-cause dementia. We also determined anticholinergic DBI (AChDBI) and sedative DBI (SDBI) separately and in combination as total drug burden (TDB). Results Nearly one half of patients (48%) used at least one DBI-contributing drug. In 33% of the patients, drug burden was moderate (0 0.05). Conclusions A lack of association between drug burden and physical or cognitive function in this sample of patients with dementia could imply that drug prescribing is more optimal for patients with dementia compared with healthy older populations. However, such an interpretation of the data warrants scrutiny as several dementia-related factors may confound the results of the study.

The objective was to evaluate the effects of a multicomponent dyadic intervention on the cognitive functioning of people with dementia living at home in a randomized controlled trial. People with dementia and their family caregivers (n = 111) were randomly assigned to 8 home-based sessions including physical exercise and support or a minimal intervention consisting of monthly written information bulletins and monthly phone calls. Memory, executive functioning (EF), and attention were assessed at baseline, and after 3 (postmeasurement) and 6 months (follow-up). Data were analyzed by using generalized estimating equations (GEE). A small, significant effect was found on attention. No effects were found on memory and EF. Finding only a small significant effect might be explained by the ineffectiveness of the intervention, but also by moderate treatment adherence or a lack of room for improvement because half of the people with dementia were already receiving care in a day care facility.

Background An enriched environment for residents with dementia may have a positive effect on the rest-activity rhythm. A small scaled homelike special care unit might be such an enriched environment. The present study shows whether the rest-activity rhythm of residents with moderate to severe dementia responds positively to a transfer from a regular Special Care Unit (SCU) to a small scaled homelike SCU. Methods Initially, a group of 145 residents living in a regular SCU participated. Out of this group, 77 residents moved to a small scaled homelike SCU. This group was compared to the group of 68 residents that remained at the regular SCU. Rest-activity rhythm was assessed by means of actigraphy and observation scales before and after relocation. Results No significant main effects nor significant interaction effects in intradaily and interdaily activity were found for the data of 38 residents in the small scaled homelike SCU and 20 residents of the regular SCU. The effect sizes, however, ranged from small to large. Conclusions Considering the effect sizes, a new study with a larger number of participants is necessary before firm conclusions can be drawn.

Objective: The aim was to examine whether the presence of pain (based on physical conditions and participants' report) and self-reported pain experience in adults with Down syndrome (DS) differ from general population controls.Design: Cross-sectional study of 224 adults with DS (mean age = 38.1 years, mild-severe intellectual disabilities) and 142 age-matched controls (median age = 40.5 years, mean estimated IQ = 105.7) in the Netherlands.Methods: File-based medical information was evaluated. Self-reported presence and experience of pain were assessed in rest and after movement during a test session (affect with facial affective scale (FAS: 0.04-0.97), intensity assessed with numeric rating scale (NRS: 0-10).Results: Compared with controls, more DS participants had physical conditions that may cause pain and/or discomfort ( p = .004, 50% vs 35%), but fewer DS participants reported pain during the test session ( p = .003, 58% vs 73%). Of the participants who indicated pain and comprehended self-reporting scales ( n = 198 FAS, n = 161 NRS), the DS group reported a higher pain affect and intensity than the controls ( p Conclusions: Not all adults with DS and painful/discomforting physical conditions reported pain. Those who did indicated a higher pain experience than adults from the general population. Research into spontaneous self-report of pain, repeated pain assessment, and acute pain is needed in people with DS for more insight into pain experience and mismatches between self-report and medical information.

Objective: The aim of the present study was to examine whether cognitive functioning (i.e., memory and executive functioning) is related to self-reported presence of pain (i.e., affirmative answer to the question whether the individual feels pain) and experience of pain (i.e., intensity and affect) in adults with Down syndrome (DS).Design, Setting, and Subjects: Cross-sectional study of 224 adults with DS (mean age = 38.1 years, mild-severe intellectual disabilities) in the Netherlands.Methods: File-based medical information was evaluated. Self-reported presence and experience of pain were assessed during a test session, both in rest and after movement (affect with the facial affective scale [FAS], intensity with the numeric rating scale [NRS]). Neuropsychological tests for memory and executive functioning were used.Results: Participants with lower memory scores were more likely to report the presence of pain, while controlling for age, gender, physical conditions that may cause pain, language comprehension, and vocabulary ( p = .030, 58.4% classification rate, N = 154). No statistically significant associations were found between executive functioning and self-reported presence of pain or between cognitive functioning and self-reported pain experience.Conclusions: Memory seems to be related to the self-reported presence of pain in adults with DS after explicit inquiry, although the clinical use of this model is yet limited. Therefore, further research is needed for insight into the role of cognitive processes in self-report (e.g., involving aspects such as acquiescence and repeated measurements) to evaluate whether neuropsychological examination could contribute to pain assessment in DS.
