Background: Even though poor lighting at nighttime is an important risk factor for falls (and most falls occur during the night), lighting interventions to improve nightly lighting from bed to bathroom are rarely evaluated for fall prevention.Objective: We tested the hypothesis that an automated guiding light would reduce nightly fear of falling (FOF) and increase sleep quality of community-dwelling older people.Methods: This study had a pragmatic uncontrolled before-after design, including participants during a period of 8 months if they (i) were aged at least 65 years, (ii) ambulated independently at night, and (iii) had no cognitive or audiovisual impairments obstructing outcome measurement. Automated LED strips (GightTM) were installed in the participants' homes. The primary outcome measure was overnight FOF on a scale of 0-10. Secondary outcome measures included sleep quality on a scale of 0-10 and fall rate. Additionally, a sample of participants was interviewed about their experiences with Gight.Results: Sixty-four participants were included (mean age: 80.8 ± 8.1 years; 89% living independently). Mean study length was 118 days (range: 30-231). In the intention-to-treat analysis, overnight FOF declined from 5.5 ± 3.0 to 3.8 ± 3.2 (p = 0.001), and sleep quality increased from 6.7 ± 2.4 to 7.4 ± 1.7 (p = 0.012). The fall rate during the study was too low to detect changes. Participants appreciated Gight (8.4 ± 0.8 on a scale of 10), and the majority (57%) reported a subjective decrease in FOF.Conclusion: Gight shows promising results for overnight FOF and sleep quality, but the effect of lighting interventions on fall rate should be evaluated further before widespread implementation.

Aims: The aim of this study was to examine physical activity and sedentary behaviour characteristics of ambulatory and community-dwelling patients with dementia compared to cognitively healthy age-, sex- and weight-matched controls. Methods: In this cross-sectional study, we included community-dwelling dementia patients (n = 45, age 79.6 ± 5.9 years, Mini-Mental State Examination [MMSE] 22.8 ± 3.2) and matched controls (n = 49, age 80.0 ± 7.7 years, MMSE 29.0 ± 1.2). Participants wore a wrist accelerometer for 7 days to assess sedentary time, sedentary bout duration and time spent in very light, light-to-moderate and moderate-to-vigorous physical activities. Results: Relative sedentary time and sedentary bout duration was significantly higher in dementia patients than in controls (median [interquartile range] 57% [49–68] vs. 55% [47–59] and 18.3 [16.4–21.1] min vs. 16.6 [15.3–18.4] min, p = 0.042 and p = 0.008, respectively). In addition, dementia patients spent a lower percentage of their waking time in light-to-moderate and moderate-to-vigorous intensity physical activities (20% [15–23] vs. 22% [18–25] and 5% [2–10] vs. 10% [5–13], p = 0.017 and p = 0.001, respectively). Conclusion: We revealed that dementia patients are more sedentary and perform less physical activity than cognitively healthy controls. This may have clinically important consequences, given the observation that sedentary behaviour and little physical activity independently predict all-cause mortality and morbidity.

Background: Recent research suggests using an imaginary version of the Timed Up and Go test (TUG) for a first assessment of cognitive impairment. By using the time difference between a real (TUGr) and an imagined (TUGi) TUG task, the objective of this study was to examine the effect of cognitive impairment on motor imagery ability. Methods: Fifty-two participants (mean age 69.3 ± 4.0 years) with mild cognitive impairment or subjective cognitive impairment were included in this study. The time difference between the TUGr and the TUGi was used as the main outcome. The Trail Making Test part B (TMT B), the ratio between TMT A and TMT B, and the Montreal Cognitive Assessment (MoCA) battery were the main independent variables. Results: The difference between TUGr and TUGi performance time and the TMT B performance time increased with decreasing cognitive function (p < 0.01). There was no relationship between TUGr and TUGi performance time and TMT B/A ratio. There were significant correlations between TUG time differences and the MoCA score (r = -0.489, p < 0.01), the TMT B (r = 0.364, p < 0.01), and the TMT B/A ratio (r = 0.377, p < 0.01). Conclusion: The combination of TUGr and TUGi may have added value in assessing cognitive impairment, which is a possible pre-stage of dementia. [ABSTRACT FROM AUTHOR]

Background: Until now, multiple reviews on the pharmacological treatment of dementia have been published. Methods: We performed a scoping review to summarize research findings and to identify gaps in the existing literature. We searched the literature and assessed the risk of bias of the included reviews. A team of clinical experts assessed the fields in which more research is necessary. Fifty-five reviews with a low risk of bias were included, most of them concerning the treatment of cognitive decline (n = 16) and behavioral symptoms (n = 10) in Alzheimer's disease (AD). For cognitive impairment, cholinesterase inhibitors (n = 13) and memantine (n = 7) were described most frequently. Little information was found about the treatment of depression in dementia. Conclusions: For many current treatments, there is sufficient evidence. New research should focus on the symptomatic treatment of the earliest and most salient complaints in AD as well as on disease-modifying interventions acting at the level of the amyloid cascade. © 2013 S.

Background/Aims: To identify prodromal Alzheimer's disease (AD) subjects using a data-driven approach to determine cognitive profiles in mild cognitive impairment (MCI). Methods: A total of 881 MCI subjects were recruited from 20 memory clinics and followed for up to 5 years. Outcome measures included cognitive variables, conversion to AD, and biomarkers (e.g. CSF, and MRI markers). Two hierarchical cluster analyses (HCA) were performed to identify clusters of subjects with distinct cognitive profiles. The first HCA included all subjects with complete cognitive data, whereas the second one selected subjects with very mild MCI (MMSE ≥28). ANOVAs and ANCOVAs were computed to examine whether the clusters differed with regard to conversion to AD, and to AD-specific biomarkers. Results: The HCAs identified 4-cluster solutions that best reflected the sample structure. One cluster (aMCIsingle) had a significantly higher conversion rate (19%), compared to subjective cognitive impairment (SCI, p < 0.0001), and non-amnestic MCI (naMCI, p = 0.012). This cluster was the only one showing a significantly different biomarker profile (Aβ42, t-tau, APOE ε4, and medial temporal atrophy), compared to SCI or naMCI. Conclusion: In subjects with mild MCI, the single-domain amnestic MCI profile was associated with the highest risk of conversion, even if memory impairment did not necessarily cross specific cut-off points. A cognitive profile characterized by isolated memory deficits may be sufficient to warrant applying prevention strategies in MCI, whether or not memory performance lies below specific z-scores. This is supported by our preliminary biomarker analyses. However, further analyses with bigger samples are needed to corroborate these findings. Copyright © 2013 S.

Background/Aims: The prevalence of multiple psychiatric symptoms (MPS) in psychogeriatric patients is about 80%. MPS have negative effects on caregivers; 70-80% of caregivers are moderately to heavily burdened. We tested an integrative psychotherapeutic programme (IRR) focused on MPS as well as caregiver burden. To develop decision rules in indicating IRR, prognostic potentialities of diagnostic and functional baseline variables for a favourable outcome of IRR were identified. Methods: Patients with a DSM-IV classification of dementia, amnestic disorders or other cognitive disorders were followed in a randomised controlled trial, comparing IRR (n = 81) with usual nursing home care (n = 87). Assessments at T1 (intake) and T2 (6 months' follow-up). Results: In the combined prognostic models Alzheimer dementia showed significant prognostic qualities for improvement on NPI sum severity (OR 3.01), IRR on general burden and competence of caregiver (OR 2.29 and 3.34). Cognitive functions had low prognostic value. Conclusion: Prognostic modelling of positive change on severity of MPS and caregiver burden was feasible. Applying three decision rules, all resulted in IRR as indicated intervention. It seems justified to refer psychogeriatric patients suffering from a broad range of cognitive function disorders, specifically patients with dementia of the Alzheimer type, to the IRR programme.

Background: Patients with mild cognitive impairment (MCI) have to deal with an uncertain prognosis and also face a multitude of memory-related problems and psychosocial consequences. A newly developed group programme proved to be feasible, however, it needed confirmation by a controlled study. Aim: This controlled study evaluates this group therapy for MCI patients aimed to help them accept and manage the memory problems and the psychosocial consequences. The programme combines elements from psychoeducation, cognitive rehabilitation and cognitive-behavioural therapy. Patients and Methods: Ninety-three MCI patients received treatment, with 30 patients being first assigned to a waiting list, thus serving as their own control group. Pre- and post-treatment acceptance and helplessness were assessed using subscales of the Illness Cognition Questionnaire, while distress and general well-being were gauged with the Geriatric Depression Scale and subscales of the RAND-36. Results: Linear mixed model analyses showed that, relative to the controls, acceptance had increased more in the intervention group compared to the waiting-list period (p = 0.034). Distress and general well-being showed no changes. Treatment responders demonstrating a clinically significant effect on acceptance and two of three secondary outcome measures had higher baseline levels of helplessness and fewer self-reported memory complaints in daily life than patients who did not improve. Conclusion: The intervention helped the patients deal better with their uncertain future in that they were overall better able to accept their condition, with especially the female patients showing a decrease in helplessness cognitions, although the effects were relatively small.

Background: Visual estimation of age can be used as a measure of biological age (BA) and has become useful in predicting life expectancy.Objective: The aim of this study was to quantify the interrater agreement of experienced geriatricians in visual estimation of BA.Methods: In a prospective controlled study, 4 experienced geriatricians estimated the BA of 43 elderly subjects (mean age 82.5 +/- 6.0 years) during a short standardized interview, using a checklist of age-associated changes in appearance, communication and mobility. Interrater agreement was calculated by analysis of variance and expressed as the intra-class coefficient of correlation (ICCC).Results: The ICCC of the BA estimation was 0.76 (p < 0.001). Within-subject standard deviation of the estimate was 3. 4 years. On average, BA was 4.8 (+/-4.4) years lower than chronological age (p < 0.001).Conclusion: Visual estimation of BA based on a simple checklist has a good interrater agreement and therefore should be part of geriatric assessment.
