Abstract
INTRODUCTION People with dementia often experience behavioral and psychological symptoms of dementia (BPSD), which are a major cause of caregiver burden and institutionalization. Therefore, we conducted a double-blind, parallel-group randomized controlled trial to examine the efficacy of blue-enriched light therapy for BPSD in institutionalized older adults with dementia. METHODS Participants were enrolled and randomly allocated into blue-enriched light therapy (N = 30) or the conventional light group (N = 30) for 60 min in 10 weeks with five sessions per week. The primary outcome was sleep quality measured by actigraphy and Pittsburgh Sleep Quality Index (PSQI). The secondary outcome was overall BPSD severity (Cohen-Mansfield Agitation Inventory [CMAI] and Neuropsychiatric Inventory [NPI-NH]). The outcome indicators were assessed at baseline, mid-test, immediate posttest, 1-month, 3-month, and 6-month follow-up. The effects of the blue-enriched light therapy were examined by the generalized estimating equation model. RESULTS Blue-enriched light therapy revealed significant differences in the objective sleep parameters (sleep efficiency: β = 5.81, Waldχ2 = 32.60, CI: 3.82; 7.80; sleep latency: β = -19.82, Waldχ2 = 38.38, CI:-26.09; -13.55), subjective sleep quality (PSQI: β = -2.07, Waldχ2 = 45.94, CI: -2.66; -1.47), and overall BPSD severity (CMAI: β = -0.90, Waldχ2 = 14.38, CI: -1.37; -0.44) (NPI-NH: β = -1.67, Waldχ2 = 30.61, CI: -2.26; -1.08) compared to conventional phototherapy immediate posttest, 1-month, 3-month, and 6-month follow-up. Furthermore, the effects for sleep efficiency and sleep latency lasted for up to 6 months. In the subscale analysis, the differences of the behavioral symptoms changed significantly between the groups in physical/nonaggressive (CI: -1.01; -0.26) and verbal/nonaggressive (CI: -0.97; -0.29). CONCLUSIONS Blue-enriched light therapy is a feasible low-cost intervention that could be integrated as a comprehensive therapy program for BPSD among older adults with dementia.

[PMID: 36410392 DOI: 10.1016/j.jamda.2022.10.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 10/14/2022] [Accepted: 10/14/2022] [Indexed: 11/19/2022]
Abstract
OBJECTIVES Because light can regulate sleep rhythms, numerous studies have investigated whether light therapy can improve sleep disorders in older people, but its efficacy remains controversial. Therefore, this systematic review aimed to examine and summarize current evidence about the efficacy of light therapy to improve sleep for older people in residential long-term care. DESIGN Systematic review. SETTING AND PARTICIPANTS Older people living in long-term care settings. METHODS Systematic searches were conducted in the databases PubMed, Web of Science, Cochrane, EMBASE, CINAHL, China National Knowledge Infrastructure, China Science and Technology Journal Database, WanFang, Chinese Biomedical Literature Database, and in reference lists within relevant articles. Studies were eligible for inclusion if they evaluated light therapy for older people with sleep disorders in long-term care settings. RESULTS This systematic review includes 21 articles, summarizing light therapy with different durations and intensities. The light intervention was typically administered between 7:00 and 12:00 am for 30-120 minutes. The interventions lasted from 1 week to several months, and the intensity of the light intervention usually ranged from 2500 to 10,000 lux. Short-term exposure (30-60 minutes) with high light levels (≥10,000 lux), relatively long-term exposure (1-2 hours) with moderate light levels (2500-10,000 lux), or long-term exposure (1-4 hours or full day) with low light levels (≤2500 lux) were associated with improved sleep indicators for older people in long-term care settings. CONCLUSIONS AND IMPLICATIONS The efficacy of light therapy in long-term care settings may be affected by the duration of exposure, time and length of intervention, intensity of light, and equipment used to administer the therapy. Further research must be conducted to optimize light therapy parameters. Large, high-quality randomized controlled trials are needed to deepen our understanding of the effects of light therapy on sleep in older people living in long-term care settings.

Circadian preference and sleep quality in healthy controls and psychiatric inpatients with major depressive disorder - An actigraphy study incorporating morning and evening mood assessments.

Abstract
Major depressive disorder (MDD) is frequently accompanied by sleep disturbance. Regarding diurnal preference (chronotype), sleep problems and low mood have been associated with evening orientation. Considering diurnal preference, we investigated subjective restorative value of sleep and actigraphy sleep parameters together with mood assessments twice a day, i.e. in the morning and evening, during weekdays and weekends in MDD psychiatric inpatients and healthy controls (HCs). The restorative value of sleep was higher during the weekend in HC, and bedtimes and risetimes were delayed during the weekend compared to weekdays in HC and MDD. Morning mood affected subjective sleep ratings in both groups, while association with symptom severity (BDI) in MDD remained insignificant. In HC, better evening mood was associated with later bedtimes. Regarding the chronotype in HC, evening orientation was associated with relatively low restorative value of sleep during weekdays, and morning orientation was associated with relatively higher actigraphy sleep efficiency during weekdays compared to weekend. In MDD, an association of evening orientation with later rise times could be observed, while no chronotype dependent effect emerged regarding the restorative value of sleep or sleep efficiency. Our results emphasize that research on sleep in MDD should incorporate weekdays as well as weekends, chronotype assessment, and measures of morning and evening mood, as these can be associated with ratings of the subjective restorative value of sleep (i.e. in our study, better morning mood was associated with higher restorative values), but also with behavioral sleep parameters (i.e. in our study, more positive evening mood was associated with later bedtimes). Potentially, the restorative value of sleep in MDD evening types can be improved by maintaining a regular sleep schedule, which needs to be investigated in an experimental design.

Abstract
Bright light treatment is an effective way to influence circadian rhythms in healthy adults, but previous research with dementia patients has yielded mixed results. The present study presents a primary outcome of the DEM.LIGHT trial, a 24-week randomized controlled trial conducted at nursing homes in Bergen, Norway, investigating the effects of a bright light intervention. The intervention consisted of ceiling-mounted LED panels providing varying illuminance and correlated color temperature throughout the day, with a peak of 1000 lx, 6000 K between 10 a.m. and 3 p.m. Activity was recorded using actigraphs at baseline and after 8, 16, and 24 weeks. Non-parametric indicators and extended cosine models were used to investigate rest-activity rhythms, and outcomes were analyzed with multi-level regression models. Sixty-one patients with severe dementia (median MMSE = 4) were included. After 16 weeks, the acrophase was advanced from baseline in the intervention group compared to the control group (B = -1.02, 95%; CI = -2.00, -0.05). There was no significant difference between the groups on any other rest-activity measures. When comparing parametric and non-parametric indicators of rest-activity rhythms, 25 out of 35 comparisons were significantly correlated. The present results indicate that ambient bright light treatment did not improve rest-activity rhythms for people with dementia.

Abstract
INTRODUCTION Disrupted sleep-wake cycles might be associated with an exacerbation of behavioural disturbances and accelerate disease progression in dementia. The effect of sensory stimulation for improving sleep quality is unclear. METHODS A systematic literature search was performed and all studies examining the effects of a sensory stimulation intervention (i.e. bright light, massage, acupuncture, animal-assisted interventions) on rest-activity rhythm (RAR) and/or nocturnal restlessness in nursing-home residents with dementia were included. RESULTS Sensory stimulation was shown to improve nocturnal behavioural restlessness as well as sleep duration and continuation, but the effect on the number of awakenings, RAR, and daytime sleep was negligible. Notable was the high heterogeneity between studies regarding treatments and patients' characteristics and sleep parameters. CONCLUSION Sleep quality and nocturnal restlessness in nursing-home residents with dementia may benefit from sensory stimulation. An environment with sensory stimulation may prevent or improve sleep disturbances in nursing homes, and thereby contribute to a better quality of life for their patients.

Abstract
ABSTRACT Given the increasing incidence of neurodegenerative disease (ND), recent research efforts have intensified the search for curative treatments. Despite significant research, however, existing therapeutic options for ND can only slow down the progression of the disease, but not provide a cure. Light therapy (LT) has been used to treat some mental and sleep disorders. This review illustrates recent studies of the use of LT in patients with ND and highlights its potential for clinical applications. The literature was collected from PubMed through June 2020. Selected studies were primarily English articles or articles that could be obtained with English abstracts and Chinese main text. Articles were not limited by type. Additional potential publications were also identified from the bibliographies of identified articles and the authors' reference libraries. The identified literature suggests that LT is a safe and convenient physical method of treatment. It may alleviate sleep disorders, depression, cognitive function, and other clinical symptoms. However, some studies have reported limited or no effects. Therefore, LT represents an attractive therapeutic approach for further investigation in ND. LT is an effective physical form of therapy and a new direction for research into treatments for ND. However, it requires further animal experiments to elucidate mechanisms of action and large, double-blind, randomized, and controlled trials to explore true efficacy in patients with ND.

Abstract
This systematic review aims to assess the efficacy of light therapy on behavioural and psychological symptoms of dementia (BPSD), cognition, functional status, and quality of life in older adults with cognitive impairment; and secondarily, to identify the optimal characteristics of light therapy to establish an adequate protocol for its clinical application. We searched Web of Science and Medline databases through December 2019, resulting in 36 included articles: 3 evaluated the effects on BPSD, 25 on sleep, 12 on agitation, 10 on mood, 4 on neuropsychiatric symptoms, 4 on cognition, 2 on quality of life and 2 on functional status. Literature has shown potential evidence for positive effects of light therapy on managing sleep, behavioural and mood disturbances in people with cognitive impairment, but a limited effect on cognition, quality of life and functional status. This review provides guidelines for intervention protocols with light therapy in older people with cognitive impairment.

Abstract
Dementia is a devastating disease with a global impact, and there is an urgent need for effective interventions to alleviate the accompanying disturbances in behavior, mood, sleep, and circadian rhythms. Bright light treatment (BLT) is a promising non-pharmacological intervention; however, studies have yielded conflicting results. This systematic review provides a comprehensive overview of the effect of BLT in dementia, with a specific focus on how study characteristics might have affected the available results. The included studies were small and comprised time-limited interventions and follow-ups. Light values, adherence to treatment, and time of year were not consistently reported. Varying designs, methods, and population characteristics such as age, gender, dementia diagnosis, circadian phase, and baseline symptoms may have moderated the outcomes and affected review results. The use of crossover designs and too high illumination as placebo lights might have nullified positive effects of BLT. Because some studies had negative outcomes after ambient BLT with high amounts of short wavelengths, more modest light levels should be further investigated. Employing rigorous designs and detailed reporting of intervention characteristics, i.e., the illumination, correlated color temperature, timing, and duration of light utilized, are of utmost importance to establish the optimal treatment approach in this population. Systematic review registration number: PROSPERO CRD42017051004.

Abstract
AIM Sleep disturbances are prevalent in various dementia subtypes but rarely investigated in early clinical stages. Although memory clinics have become an established institution for the early diagnosis of dementia, sleep assessment is not part of their routine diagnostics. This study aimed to examine whether subjective and objective sleep variables are related to cognitive impairment in patients referred to a memory clinic. METHODS On two consecutive days, patients underwent routine diagnostic procedures, including a neuropsychological examination (consortium to establish a registry for alzheimer's disease), and had their sleep quality evaluated by the Pittsburgh Sleep Quality Index and overnight hand-wrist actigraphy. RESULTS Data of 31 patients (age, M ± SEM: 74.1 ± 1.5; 18 women, 13 men; Clinical Dementia Rating: 0-1) were analysed. One had been diagnosed with subjective cognitive impairment, 13 with mild cognitive impairment with or without depression, and 17 with dementia syndrome due to Alzheimer's and/or cerebrovascular disease. Compared to patients with subjective or mild cognitive impairment, dementia patients showed a significantly increased nocturnal acceleration magnitude; other differences in subjective and objective sleep measures were not significant. Comparing patients with subjectively poor (Pittsburgh Sleep Quality Index > 5: n = 9) and good sleep (Pittsburgh Sleep Quality Index ≤ 5: n = 22) yielded no differences in any neuropsychological and clinical variables. In contrast, patients with low actigraphically recorded sleep efficiency (<85%: n = 11) exhibited a significantly more impaired cognitive performance than those in the high sleep efficiency group (≥85%: n = 20). Correlation analyses demonstrated that actigraphically assessed disturbed sleep continuity accompanied by increased night-time motor activity was substantially associated with cognitive impairment. CONCLUSION This study highlights that objectively assessed, but not self-reported, parameters of disturbed sleep are closely related to cognitive dysfunction in the early stages of dementia of different aetiologies. Possible diagnostic and treatment implications are discussed.

[DOI: 10.2174/1567205016666191010124011] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2019] [Revised: 08/10/2019] [Accepted: 09/08/2019] [Indexed: 12/18/2022]
Abstract
Background:
Alzheimer's Disease (AD) is often accompanied by severe sleep problems and
circadian rhythm disturbances which may to some extent be attributed to a dysfunction in the biological
clock. The 24-h light/dark cycle is the strongest Zeitgeber for the biological clock. People with AD,
however, often live in environments with inappropriate photic Zeitgebers. Timed bright light exposure
may help to consolidate sleep- and circadian rest/activity rhythm problems in AD, and may be a low-risk
alternative to pharmacological treatment.
Objective & Method:
In the present review, experts from several research disciplines summarized the
results of twenty-seven light intervention studies which used wrist actigraphy to measure sleep and circadian
activity in AD patients.
Results:
Taken together, the findings remain inconclusive with regard to beneficial light effects. However,
the considered studies varied substantially with respect to the utilized light intervention, study design,
and usage of actigraphy. The paper provides a comprehensive critical discussion of these issues.
Conclusion:
Fusing knowledge across complementary research disciplines has the potential to critically
advance our understanding of the biological input of light on health and may contribute to architectural
lighting designs in hospitals, as well as our homes and work environments.

Abstract
Worldwide, individuals are living longer due to medical and scientific advances, increased availability of medical care and changes in public health policies. Consequently, increasing attention has been focused on managing chronic conditions and age-related diseases to ensure healthy aging. The endogenous circadian system regulates molecular, physiological and behavioral rhythms orchestrating functional coordination and processes across tissues and organs. Circadian disruption or desynchronization of circadian oscillators increases disease risk and appears to accelerate aging. Reciprocally, aging weakens circadian function aggravating age-related diseases and pathologies. In this review, we summarize the molecular composition and structural organization of the circadian system in mammals and humans, and evaluate the technological and societal factors contributing to the increasing incidence of circadian disorders. Furthermore, we discuss the adverse effects of circadian dysfunction on aging and longevity and the bidirectional interactions through which aging affects circadian function using examples from mammalian research models and humans. Additionally, we review promising methods for managing healthy aging through behavioral and pharmacological reinforcement of the circadian system. Understanding age-related changes in the circadian clock and minimizing circadian dysfunction may be crucial components to promote healthy aging.

O'Caoimh R, Mannion H, Sezgin D, O'Donovan MR, Liew A, Molloy DW. Non-pharmacological treatments for sleep disturbance in mild cognitive impairment and dementia: A systematic review and meta-analysis. Maturitas 2019; 127:82-94. [PMID: 31351523 DOI: 10.1016/j.maturitas.2019.06.007] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Revised: 06/13/2019] [Accepted: 06/14/2019] [Indexed: 02/07/2023]
Abstract
No disease-modifying treatments for dementia are available. Sleep disturbance is strongly associated with cognitive impairment. Non-pharmacological treatments targeting sleep may offer an alternative therapeutic approach. We searched PubMed, CINAHL, EMBASE and the Cochrane library for non-pharmacological treatments for sleep disturbance in mild cognitive impairment (MCI) and dementia, published in English from October 1965 to 2018, including all designs, excluding studies of drug therapies. In all, 53 papers representing 48 studies were included. Participant age ranged from 67.3 to 89.4 years. Most studies (79%) had small samples (<50 participants, range 1-173) and were conducted in long-term/residential care (62%). The majority (85%) recruited participants with moderate-severe dementia; mean MMSE scores ranged from 0 to 28.3/30. Four studies examined MCI. Light therapy delivered over 1-10 weeks was the most studied stand-alone intervention (n = 27), and the majority (81.5%) of these studies found improvements on objective or subjective sleep measures, though the evidence was inconclusive with significant clinical and methodological heterogeneity. Seven multi-modal intervention studies were identified, all incorporating light exposure, and six of these reported improved sleep. Other interventions included electrotherapy stimulation (n = 4), physical exercises/activities (n = 4), acupressure/acupuncture (n = 3) and mindfulness/cognitive behavioural therapy (n = 3). Those examining MCI utilised different mono-modal approaches. A meta-analysis of data from randomised controlled trials showed a statistically significant (mean difference = 3.44, 95% CI: 0.89-5.99, I2=0%; p = 0.008) improvement in sleep efficiency between interventions and controls, favouring the pooled interventions (bright light, multi-domain and other therapies). No other significant differences in sleep or non-sleep outcomes were found. While evidence is available for non-pharmacological sleep interventions, particularly multi-domain approaches, studies were diverse and had small samples. More research examining multi-modal interventions, community-dwellers and those with MCI is required.

Abstract
BACKGROUND Bright light treatment is a therapeutic intervention mainly used to treat sleep and circadian disturbances in Alzheimer's disease (AD) patients. Recently, a handful of studies also focused on the effect on cognition and behavior. Conflicting findings are reported in the literature, and no definite conclusions have been drawn about its specific therapeutic effect. SUMMARY The aim of this review is to provide a critical evaluation of available evidence in this field, highlighting the specific characteristics of effective bright light treatment. Eligible studies were required to assess at least one of the following outcome measures: sleep, cognition, mood, and/or behavior (e.g., depression, agitation). A total of 32 articles were included in this systematic review and identified as research intervention studies about light treatment in AD. The quality of the papers was evaluated based on the US Preventive Service Task Force guidelines. Key Messages: Overall, the current literature suggests that the effects of light treatment in AD patients are mixed and may be influenced by several factors, but with a general trend toward a positive effect. Bright light seems to be a promising intervention treatment without significant adverse effects; therefore, further well-designed randomized controlled trials are needed taking into account the highlighted recommendations.

Abstract
OBJECTIVES Lighting is one of the environmental factors which can improve patient sleep in healthcare environments. Due to the high degree of variation in study designs and results on this topic, the implications have been difficult to interpret. This review consolidates studies on the impact of bright light exposure on sleep to identify lighting conditions that can be applied and researched in future healthcare environments. METHODS We searched for peer-reviewed articles on the impact of light on sleep or sleep-related outcomes in healthcare settings. We provided detailed analysis of the direct links between light and sleep, and a more cursory analysis of links between light and sleep-related factors, from 34 articles which met our inclusion criteria. RESULTS The current state of the literature includes evidence on how various durations and intensities of morning, midday, and evening bright light exposure, as well as whole-day light exposure interventions can improve specific aspects of sleep. Lighting interventions differed in all attributes (illuminance levels, exposure time, exposure duration, and spectral qualities) but showed promising results in improving patients' sleep. CONCLUSIONS Short-term bright light exposure in the morning, up to 2 hr of moderate (3,000-10,000 lux) morning exposures, up to 4 hr of moderate evening exposure, and whole-day exposures to lower illuminance levels (<3,000 lux) can improve patient sleep outcomes. Based on new findings on the mechanism through which light impacts sleep, future studies should be more specific about the spectral qualities of light sources.

Abstract
The purpose of this article is to provide tactics for the behavior analyst to effectively evaluate the evidence base for an unfamiliar nonbehavioral intervention when expanding services. Just as behavior analysts must be aware of fad treatments in autism likely to be encountered, so, too, should practitioners become familiar with potential fad treatments in any expanded area of practice. The present article extends previous work by considering challenges surrounding contact with nonbehavioral literature in the context of an expanded consumer base. The article also considers ethical interactions with nonbehavioral professionals following appraisal of the intervention, and how adopting the strategies listed here can aid in establishing oneself as a resource. Associated barriers and solutions are presented around four tactics: (a) searching the literature, (b) recognizing and evaluating the common properties of fad treatments, (c) distinguishing quality of evidence, and (d) ascertaining behavioral mechanisms of action. Examples from gerontology will be provided to illustrate the use of the proposed tactics.

Abstract
Background Disturbances in sleep and circadian rhythms are common among residents of long-term care facilities. In this systematic review, we aim to identify and evaluate the literature documenting the outcomes associated with non-pharmacological interventions to improve nighttime sleep among long-term care residents. Methods The Preferred Reporting Items for Systematic Reviews guided searches of five databases (MEDLINE, Embase, CINAHL, Scopus, and Cochrane Library) for articles reporting results of experimental or quasi-experimental studies conducted in long-term care settings (nursing homes, assisted-living facilities, or group homes) in which nighttime sleep was subjectively or objectively measured as a primary outcome. We categorized each intervention by its intended use and how it was administered. Results Of the 54 included studies evaluating the effects of 25 different non-pharmacological interventions, more than half employed a randomized controlled trial design (n = 30); the others used a pre-post design with (n = 11) or without (n = 13) a comparison group. The majority of randomized controlled trials were at low risk for most types of bias, and most other studies met the standard quality criteria. The interventions were categorized as environmental interventions (n = 14), complementary health practices (n = 12), social/physical stimulation (n = 11), clinical care practices (n = 3), or mind-body practices (n = 3). Although there was no clear pattern of positive findings, three interventions had the most promising results: increased daytime light exposure, nighttime use of melatonin, and acupressure. Conclusions Non-pharmacological interventions have the potential to improve sleep for residents of long-term care facilities. Further research is needed to better standardize such interventions and provide clear implementation guidelines using cost-effective practices.

Abstract
BACKGROUND Sleep fragmentation is common among those with advanced serious illness. Nonpharmacological interventions to improve sleep have few, if any, adverse effects and are often underutilized in these settings. OBJECTIVE We aimed to summarize the literature related to nonpharmacological interventions to improve sleep among adults with advanced serious illness. METHODS We systematically searched six electronic databases for literature reporting sleep outcomes associated with nonpharmacological interventions that included participants with advanced serious illness during the period of 1996-2016. RESULTS From a total of 2731 results, 42 studies met the inclusion criteria. A total of 31 individual interventions were identified, each evaluated individually and some in combination with other interventions. Twelve of these studies employed either multiple interventions within an intervention category (n = 8) or a multicomponent intervention consisting of interventions from two or more categories (n = 5). The following intervention categories emerged: sleep hygiene (1), environmental (6), physical activity (4), complementary health practices (11), and mind-body practices (13). Of the 42 studies, 22 demonstrated a statistically significant, positive impact on sleep and represented each of the categories. The quality of the studies varied considerably, with 17 studies classified as strong, 17 as moderate, and 8 as weak. CONCLUSIONS Several interventions have been demonstrated to improve sleep in these patients. However, the small number of studies and wide variation of individual interventions within each category limit the generalizability of findings. Further studies are needed to assess interventions and determine effectiveness and acceptability.

Abstract
STUDY OBJECTIVES Sleep disturbances are commonly reported by cancer survivors. Systematic light exposure using bright light has been used to improve sleep in other populations. In this secondary data analysis, the effect of morning administration of bright light on sleep and sleep quality was examined in a mixed group of fatigued cancer survivors. METHODS Forty-four cancer survivors screened for cancer-related fatigue were randomized to either a bright white light or a comparison dim red light condition. Participants were instructed to use a light box every morning for 30 minutes for 4 weeks. Wrist actigraphy and the Pittsburgh Sleep Quality Index were administered at 4 time points: prior to light treatment (baseline), 2 weeks into the intervention, during the last week of the intervention, and 3 weeks postintervention. Thirty-seven participants completed the end-of-intervention assessment. RESULTS Repeated-measures linear mixed models indicated a statistically significant time × treatment group interaction effect with sleep efficiency improving more in the bright light condition over time compared with the dim light condition (F3,42 = 5.55; P = .003) with a large effect size (partial η2 = 0.28). By the end of the intervention and 3 weeks postintervention, mean sleep efficiency in the bright light group was in the normal range. Medium to large effect sizes were also seen in sleep quality, total sleep time, and wake after sleep onset for participants favoring the bright light condition. CONCLUSIONS The results suggest that systematic bright light exposure in the morning may have beneficial effects on sleep in fatigued cancer survivors. Larger scale efficacy trials are warranted.

Abstract
Chronotherapeutics are well established for the treatment of depression and associated sleeping problems in adults. However, effects are still understudied in adolescents. Two pilot studies highlighted the crucial role of sleep when it comes to the treatment of depression, by means of chronotherapeutics, in adolescents. The aim of the present study was to investigate the role of adjunctive wake therapy (WT) in addition to bright light therapy (BLT) with respect to sleep behaviors. In the present study, 62 depressed inpatients (aged 13-18 years; diagnosed with Beck Depression Inventory Revision) were randomly assigned to two groups: BLT only (BLT-group) and a combination of BLT and WT (COMB-group). After one night of WT adolescents in the COMB-group revealed longer sleep durations, time in bed, advanced sleep onset, less wakes during night and an improved sleep efficiency. However, one night of WT plus BLT had no additional effect on sleep parameters compared with BLT-group in the long run. Therefore, future studies should assess whether more nights of WT might lead to more sustainable effects.

Abstract
This study was designed as an intervention study to determine the effect of light therapy on sleep problems and sleep quality of elderly people. The study sample was composed of a total of 61 elderly persons from Social Security Institution Narlıdere Municipal Nursing Home, 30 in the test group and 31 in the control group. Those 65 years and older, not diagnosed with major depression, not exercising regularly, not having sun allergy, not using sleeping pills, independent in activities of daily living, and having bad sleep quality were included in the study. The Pittsburgh Sleep Quality Index, the Demographic Data Form, and the Follow-up Form for Elderly were used for data collection, whereas the Pittsburgh Sleep Quality Index was used for sample selection. It was found that exposure to direct sunlight between 8 AM and 10 AM for 5 days seems to be effective in increasing the global sleep quality score (P < .001). In light of the findings in this study, it is suggested that allocating living places in the institution's architectural setting and providing social opportunities for elderly persons to get direct sunlight exposure can help increase the sleep quality of older adults.

Abstract
BACKGROUND Previous studies have suggested that visiting dogs can have positive effects on elderly people in nursing homes. We wanted to study the effects of biweekly dog visits on sleep patterns and the psychiatric well-being of elderly people. METHODS A total of 100 residents (median age: 85.5 years; [79; 90]) from four nursing homes were randomly assigned to receive biweekly visits for 6 weeks from a person accompanied by either a dog, a robot seal (PARO), or a soft toy cat. Sleep patterns were measured using actigraphy technology before, during (the third and sixth week), and after the series of visits. The participants were weighed and scored on the Geriatric Depression Scale, the Gottfries-Bråne-Steen Scale, and the Mini-Mental State Examination before and after the visit period. RESULTS We found that sleep duration (min) increased in the third week when visitors were accompanied by a dog rather than the robot seal or soft toy cat (dog: 610 ± 127 min; seal: 498 ± 146 min; cat: 540 ± 163 min; F2,37 = 4.99; P = 0.01). No effects were found in the sixth week or after the visit period had ended. We found that visit type had no effect on weight (F2,88 = 0.13; P > 0.05), body mass index (F2,86 = 0.33; P > 0.05), Geriatric Depression Scale (F2,82 = 0.85; P > 0.05), Gottfries-Bråne-Steen Scale (F2,90 = 0.41; P > 0.05), or Mini-Mental State Examination (F2,91 = 0.35; P > 0.05). Furthermore, we found a decrease in the Geriatric Depression Scale during the experimental period (S = -420; P < 0.05), whereas cognitive impairment worsened as shown by a decrease in Mini-Mental State Examination score (S = -483; P < 0.05) and an increase in the Gottfries-Bråne-Steen Scale (t = 2.06; P < 0.05). CONCLUSION Visit type did not affect the long-term mental state of the participants. The causal relationship between sleep duration and dog-accompanied visits remains to be explored.

Abstract
A systematic literature review and meta-analyses (where appropriate) were performed and the GRADE approach was used to update the previous American Academy of Sleep Medicine Practice Parameters on the treatment of intrinsic circadian rhythm sleep-wake disorders. Available data allowed for positive endorsement (at a second-tier degree of confidence) of strategically timed melatonin (for the treatment of DSWPD, blind adults with N24SWD, and children/ adolescents with ISWRD and comorbid neurological disorders), and light therapy with or without accompanying behavioral interventions (adults with ASWPD, children/adolescents with DSWPD, and elderly with dementia). Recommendations against the use of melatonin and discrete sleep-promoting medications are provided for demented elderly patients, at a second- and first-tier degree of confidence, respectively. No recommendations were provided for remaining treatments/ populations, due to either insufficient or absent data. Areas where further research is needed are discussed.

Abstract
AIM The purpose of this study was to examine the effects of bright light exposure on behavioral and psychological symptoms of dementia (BPSD), including sleep disturbances and the burden on caregivers in institutionalized elderly with cognitive decline. METHODS The subjects included eight people with cognitive decline (mean [SD] age, 79.9 [9.1] years) living in geriatric healthcare facilities for the elderly. BPSD and the burden on caregivers were measured over three weeks using the CMAI (Cohen-Mansfield Agitation Inventory), NPI-NH (Neuropsychiatric Inventory-Nursing Home Version) and J-ZBI (Modified Japanese Version of the Zarit Caregiver Burden Interview) at the end of each week. During the second week, the subjects received either 12,000 K (white) or 2,400 K (orange) of light corresponding to approximately 2,000 lux from a light-emitting diode (LED) device, measured before the eyes in the gaze direction, from 9 : 00 to 9 : 30 during occupational tasks, such as origami and coloring. Differences in the variables obtained at the different weeks were assessed using ANOVA with multiple comparisons. RESULTS The scores for the severity of BPSD, including sleep disturbances and the burden on caregivers, on the NPI-NH significantly (P<0.05) improved following the treatment with white light exposure, while the scores for the MMSE and J-ZBI did not change over the three-week study period. CONCLUSIONS These results suggest that exposure to white bright light during occupational tasks in the morning may have a benefit in improving BPSD, including sleep disturbances and the burden on caregivers.

Abstract
AIMS AND OBJECTIVES This study aimed to evaluate effects of a non-pharmacological intervention on sleep, activity and fatigue in patients receiving peritoneal dialysis by the use of both actigraphy registration and self-assessed questionnaires. BACKGROUND Insomnia is estimated to affect up to 60% of haemo- and peritoneal dialysis patients. It is associated with two common uremic symptoms, pruritus and restless legs syndrome. To our knowledge, no interventions have been evaluated by actigraphy. DESIGN A prospective multiple baseline single-case experimental design. METHODS Two women and seven men with sleep problems, 48-77 years, treated with PD participated in a 17-week study from January 2009 to February 2011. Two interventions were separately implemented. First, a pressure-relieving mattress and second, a four week individual sleep hygiene and sleep scheduling intervention. The two interventions were evaluated both objectively by actigraphy and subjectively by questionnaires. RESULTS A total of 315 sleep-wake cycles from nine individuals were evaluated. Three patients improved clinically significantly in five or more of the nine outcomes, i.e. sleep onset latency, nocturnal sleep duration, numbers and duration of napping, movement and fragmentation index, number of steps, metabolic equivalent unit, sleep efficiency and fatigue. The other six patients also showed improvements but to a lesser degree. Physical activity advice was the intervention that yielded most sleep improvements. CONCLUSIONS This study illuminates the need for regular assessment of sleep and tiredness. It also demonstrates how a non-pharmacological treatment and self-management can be applied with renal supportive care to improve sleep quality. RELEVANCE TO CLINICAL PRACTICE This study is a clinical example of a non-pharmacological intervention with supportive care and self-management. This model can improve health and reduce the pharmacological burden because hypnotics can be replaced by sleep hygiene self-care activities.

Abstract
Sleep disorders are common in patients with Alzheimer's disease (AD). An important aspect of intervention studies in patients with sleep disorders is the choice of assessment strategy. This paper presents a literature review concerning assessment strategies for measuring sleep in intervention studies with AD patients, with a focus on actigraphy. Thirty-seven articles were selected for this review, having analysis of sleep/nocturnal rhythm disturbances by actigraphy as the primary or secondary outcome. The advantages and limitations of actigraphy were discussed vis-à-vis polysomnography and subjective interventions. The following methodological aspects were addressed: impact of experimental design and patient setting, inclusion and exclusion criteria, placement of the actigraphy device, adherence to the regimen, duration of recordings and the choice of sleep parameters. Our analyses suggest that the methods used in intervention studies encompassing sleep disorders and dementia could be improved by increasing accuracy of diagnosis, categorization of sleep disturbances, adherence to actigraphy, and by clearly defining the variables and endpoints in each study. Also, controlling variables that could interfere with sleep and describing the data processing and analysis might improve interpretation of results.

Abstract
Alzheimer’s disease (AD) is characterised, not only by cognitive deficits and neuropathological changes, but also by several non-cognitive behavioural symptoms that can lead to a poorer quality of life. Circadian disturbances in core body temperature and physical activity are reported in AD patients, although the cause and consequences of these changes are unknown. We therefore characterised circadian patterns of body temperature and activity in male triple transgenic AD mice (3xTgAD) and non-transgenic (Non-Tg) control mice by remote radiotelemetry. At 4 months of age, daily temperature rhythms were phase advanced and by 6 months of age an increase in mean core body temperature and amplitude of temperature rhythms were observed in 3xTgAD mice. No differences in daily activity rhythms were seen in 4- to 9-month-old 3xTgAD mice, but by 10 months of age an increase in mean daily activity and the amplitude of activity profiles for 3xTgAD mice were detected. At all ages (4–10 months), 3xTgAD mice exhibited greater food intake compared with Non-Tg mice. The changes in temperature did not appear to be solely due to increased food intake and were not cyclooxygenase dependent because the temperature rise was not abolished by chronic ibuprofen treatment. No β-amyloid (Aβ) plaques or neurofibrillary tangles were noted in the hypothalamus of 3xTgAD mice, a key area involved in temperature regulation, although these pathological features were observed in the hippocampus and amygdala of 3xTgAD mice from 10 months of age. These data demonstrate age-dependent changes in core body temperature and activity in 3xTgAD mice that are present before significant AD-related neuropathology and are analogous to those observed in AD patients. The 3xTgAD mouse might therefore be an appropriate model for studying the underlying mechanisms involved in non-cognitive behavioural changes in AD.

Abstract
The amount and timing of sleep and sleep architecture (sleep stages) are determined by several factors, important among which are the environment, circadian rhythms and time awake. Separating the roles played by these factors requires specific protocols, including the constant routine and altered sleep-wake schedules. Results from such protocols have led to the discovery of the factors that determine the amounts and distribution of slow wave and rapid eye movement sleep as well as to the development of models to determine the amount and timing of sleep. One successful model postulates two processes. The first is process S, which is due to sleep pressure (and increases with time awake) and is attributed to a 'sleep homeostat'. Process S reverses during slow wave sleep (when it is called process S'). The second is process C, which shows a daily rhythm that is parallel to the rhythm of core temperature. Processes S and C combine approximately additively to determine the times of sleep onset and waking. The model has proved useful in describing normal sleep in adults. Current work aims to identify the detailed nature of processes S and C. The model can also be applied to circumstances when the sleep-wake cycle is different from the norm in some way. These circumstances include: those who are poor sleepers or short sleepers; the role an individual's chronotype (a measure of how the timing of the individual's preferred sleep-wake cycle compares with the average for a population); and changes in the sleep-wake cycle with age, particularly in adolescence and aging, since individuals tend to prefer to go to sleep later during adolescence and earlier in old age. In all circumstances, the evidence that sleep times and architecture are altered and the possible causes of these changes (including altered S, S' and C processes) are examined.

Abstract
BACKGROUND The increasing prevalence of dementia will precipitate a significant burden in terms of the costs of caring for people with dementia over the next 30 years; sleep disturbances in dementia are an important factor contributing to this burden. METHODS We reviewed sleep disturbances in people with dementia and their carers and describe the various diagnostic, assessment and treatment strategies available to physicians in the management of this clinically significant problem. RESULTS Sleep disturbances in people with dementia and their carers (i) are highly prevalent; (ii) impact significantly on quality of life of both people with dementia and their carers; (iii) increase the rate of cognitive decline; and (iv) accelerate the breakdown of community-based care. The training of physicians in the assessment and treatment of sleep disturbances in dementia and caregiving is scant despite a wide range of assessment strategies and treatment approaches, which comprise both pharmacological (including hypnotic/sedative medications) and non-pharmacological approaches (including: environmental; psychobehavioral; exercise and activity; and multi-component interventions). Specific diagnostic criteria for sleep disturbances in people with dementia and their carers remain lacking despite established criteria for general insomnia. Further to this, proposed changes to diagnostic criteria for DSM-V do not include a specific focus for the diagnosis and management of sleep disturbances in people with dementia or their carers. CONCLUSIONS This review suggests that the improved training of physicians to meet the needs of these vulnerable groups of older people is a priority, especially in the context of a rapidly increasing demand for accurate, early diagnosis and efficient management of sleep disturbance in these groups.

Abstract
In recent decades, the hectic lifestyle of industrialized societies has wrought its effects on the quality of sleep, and these effects are evidenced by a profusion of sleep-related disorders. Regular exposure to artificial light, coupled with social and economic pressures have shortened the time spent asleep. Otherwise, Circadian Rhythm Sleep Disorders are characterized by desynchronization between the intrinsic circadian clock and the extrinsic cycles of light/dark and social activities. This desynchronization produces excessive sleepiness and insomnia. The International Classification of Sleep Disorders describes nine sleep disorders under the category of Circadian Rhythm Sleep Disorders. Currently, this diagnosis is made based on the patient's history, a sleep log alone, or the sleep logs and actigraphy conducted for at least 7 days. This review contains an overview of current treatment options, including chronotherapy, timed bright light exposure, and administration of exogenous melatonin.

Abstract
Aging is associated with substantial changes in sleep patterns, which are almost always negative in nature. Typical findings in the elderly include a reduction in the deeper stages of sleep and a profound increase in the fragmentation of nighttime sleep by periods of wakefulness. The prevalence of specific sleep disorders increases with age, such as a phase advance in the normal circadian sleep cycle, restless legs syndrome, and obstructive sleep apnea, which is increasingly seen among older individuals and is significantly associated with cardio- and cerebrovascular disease as well as cognitive impairment. Elderly patients with sleep disturbances are often considered difficult to treat; yet, they are among the groups with the greatest need of treatment. Management of sleep disturbances begins with recognition and adequate assessment. Hypnotic drugs have clearly been shown to improve subjective and objective sleep measures in short-term situations, but their role in chronic insomnia still remains to be further defined by research evidence. Non-pharmacological treatments, particularly stimulus control and sleep restriction, are effective for conditioned aspects of insomnia and are associated with a stable, long-term improvement in sleep. This review delineates the common causes of disordered sleep in older individuals, and effective diagnostic approaches and treatments for these conditions.

Abstract
Sleep-related disorders are most prevalent in the older adult population. A high prevalence of medical and psychosocial comorbidities and the frequent use of multiple medications, rather than aging per se, are major reasons for this. A major concern, often underappreciated and underaddressed by clinicians, is the strong bidirectional relationship between sleep disorders and serious medical problems in older adults. Hypertension, depression, cardiovascular disease, and cerebrovascular disease are examples of diseases that are more likely to develop in individuals with sleep disorders. Conversely, individuals with any of these diseases are at a higher risk of developing sleep disorders. The goals of this article are to help guide clinicians in their general understanding of sleep problems in older persons, examine specific sleep disorders that occur in older persons, and suggest evidence- and expert-based recommendations for the assessment and treatment of sleep disorders in older persons. No such recommendations are available to help clinicians in their daily patient care practices. The four sections in the beginning of the article are titled, Background and Significance, General Review of Sleep, Recommendations Development, and General Approach to Detecting Sleep Disorders in an Ambulatory Setting. These are followed by overviews of specific sleep disorders: Insomnia, Sleep Apnea, Restless Legs Syndrome, Circadian Rhythm Sleep Disorders, Parasomnias, Hypersomnias, and Sleep Disorders in Long-Term Care Settings. Evidence- and expert- based recommendations, developed by a group of sleep and clinical experts, are presented after each sleep disorder.

Abstract
The expanding science of circadian rhythm biology and a growing literature in human clinical research on circadian rhythm sleep disorders (CRSDs) prompted the American Academy of Sleep Medicine (AASM) to convene a task force of experts to write a review of this important topic. Due to the extensive nature of the disorders covered, the review was written in two sections. The first review paper, in addition to providing a general introduction to circadian biology, addresses "exogenous" circadian rhythm sleep disorders, including shift work disorder (SWD) and jet lag disorder (JLD). The second review paper addresses the "endogenous" circadian rhythm sleep disorders, including advanced sleep phase disorder (ASPD), delayed sleep phase disorder (DSPD), irregular sleep-wake rhythm (ISWR), and the non-24-hour sleep-wake syndrome (nonentrained type) or free-running disorder (FRD). These practice parameters were developed by the Standards of Practice Committee and reviewed and approved by the Board of Directors of the AASM to present recommendations for the assessment and treatment of CRSDs based on the two accompanying comprehensive reviews. The main diagnostic tools considered include sleep logs, actigraphy, the Morningness-Eveningness Questionnaire (MEQ), circadian phase markers, and polysomnography. Use of a sleep log or diary is indicated in the assessment of patients with a suspected circadian rhythm sleep disorder (Guideline). Actigraphy is indicated to assist in evaluation of patients suspected of circadian rhythm disorders (strength of recommendation varies from "Option" to "Guideline," depending on the suspected CRSD). Polysomnography is not routinely indicated for the diagnosis of CRSDs, but may be indicated to rule out another primary sleep disorder (Standard). There is insufficient evidence to justify the use of MEQ for the routine clinical evaluation of CRSDs (Option). Circadian phase markers are useful to determine circadian phase and confirm the diagnosis of FRD in sighted and unsighted patients but there is insufficient evidence to recommend their routine use in the diagnosis of SWD, JLD, ASPD, DSPD, or ISWR (Option). Additionally, actigraphy is useful as an outcome measure in evaluating the response to treatment for CRSDs (Guideline). A range of therapeutic interventions were considered including planned sleep schedules, timed light exposure, timed melatonin doses, hypnotics, stimulants, and alerting agents. Planned or prescribed sleep schedules are indicated in SWD (Standard) and in JLD, DSPD, ASPD, ISWR (excluding elderly-demented/nursing home residents), and FRD (Option). Specifically dosed and timed light exposure is indicated for each of the circadian disorders with variable success (Option). Timed melatonin administration is indicated for JLD (Standard); SWD, DSPD, and FRD in unsighted persons (Guideline); and for ASPD, FRD in sighted individuals, and for ISWR in children with moderate to severe psychomotor retardation (Option). Hypnotic medications may be indicated to promote or improve daytime sleep among night shift workers (Guideline) and to treat jet lag-induced insomnia (Option). Stimulants may be indicated to improve alertness in JLD and SWD (Option) but may have risks that must be weighed prior to use. Modafinil may be indicated to improve alertness during the night shift for patients with SWD (Guideline).

Abstract
AIMS To explore self-care management strategies for sleep disturbances and risk factors for poor sleep among older residents of nursing homes in Taiwan. BACKGROUND With the deterioration of health that accompanies ageing, sleep quality becomes poorer, making it a significant issue in geriatric care. However, little is known about self-care strategies for management of sleep disturbances among elders worldwide. DESIGN A cross-sectional design was used. METHODS Residents (n = 196) were recruited from nine nursing homes chosen by stratified sampling across Taiwan. The Pittsburgh Sleep Quality Index, a self-care management of sleep disturbance questionnaire and a demographic form were used to collect data. RESULTS The prevalence of poor sleep in these older nursing home residents was 46.4%. Only 48.5% of participants used self-care strategies to manage sleep disturbances. The most frequently used strategy was 'take prescribed medicines'. Self-learning was the main information source for self-care strategies. Logistic regression analysis indicated that having no spouse and a low educational level significantly predicted poor sleep. CONCLUSIONS This study revealed a high prevalence of poor sleep quality among older residents of nursing homes in Taiwan. Older residents' inability to get relief from sleep disturbances may have been because of their limited use of strategies to manage sleep disturbances. RELEVANCE TO CLINICAL PRACTICE As health care providers play an important role in helping older people to manage sleep disturbances in nursing homes, it is crucial to train nursing home staff to perform sleep assessments and provide current knowledge about sleep disturbance management. It is also necessary to pay more attention to the sleep problems of elders without spouses and with little education.

Abstract
Rest-activity rhythm disruption is a prominent clinical feature of Alzheimer's disease (AD). The origin of the altered rest-activity rhythm is believed to be degeneration of the suprachiasmatic nucleus (SCN). In accordance with the 'use it or lose it' hypothesis of Swaab [Neurobiol Aging 1991, 12: 317-324] stimulation of the SCN may prevent age-related loss of neurons and might reactivate nerve cells that are inactive but not lost. Previous studies with relatively small sample sizes have demonstrated positive effects of peripheral electrical nerve stimulation on the rest-activity rhythm in AD patients. The present randomized, placebo-controlled, parallel-group study was meant to replicate prior findings of electrical stimulation in AD in a substantially larger group of AD patients. The experimental group (n = 31) received peripheral electrical nerve stimulation and the placebo group (n = 31) received sham stimulation. Effects of the intervention on the rest-activity rhythm were assessed by using wrist-worn actigraphs. Near-significant findings on the rest-activity rhythm partially support the hypothesis that neuronal stimulation enhances the rest-activity rhythm in AD patients. Interestingly, post-hoc analyses revealed significant treatment effects in a group of patients who were not using acetylcholinesterase inhibitors concomitantly. We conclude that more research is needed before firm general conclusions about the effectiveness of electrical stimulation as a symptomatic treatment in AD can be drawn. In addition, the present post-hoc findings indicate that future studies on non-pharmacological interventions should take medication use into account.

Abstract
OBJECTIVES This study examines the correlation between actigraphic measures and a validated assessment scale of agitated behaviour in dementia, the Cohen-Mansfield Agitation Inventory (CMAI). METHODS A total of 110 patients were included. Patients either suffered from Alzheimer dementia (AD), mixed dementia (MXD), frontotemporal dementia (FTD) or diffuse Lewy body disease (DLB). All patients underwent actigraphic recordings for 48 h. CMAI was scored by professional caretakers, who were responsible for the patient during his or her actigraphic recording. RESULTS Patients with high total CMAI scores (>or= 50) clearly had higher levels of activity during the day as measured by means of actigraphy than patients with low total CMAI scores (ANOVA, F=126.75, p<0.0001). Patients with low MMSE scores (<20) also had higher activity levels during the day than patients with higher MMSE scores (ANOVA, F= 85.74, p<0.0001). Correlations between ctigraphic data and CMAI total scores were moderate but highly significant. CONCLUSION We conclude that actigraphy is a useful tool to examine agitated behaviour in dementia.

Abstract
This study determined the differences in demographic and sleep characteristics in cognitively impaired nursing home residents with and without severe sleep/wake pattern inefficiency. Identification of characteristics associated with severe sleep/wake pattern inefficiency will allow health care providers to make the best cost effective use of finite resources because they can target interventions towards those most likely to need them. This article reports the baseline characteristics of the total sample, compares the demographic and sleep characteristics of the subgroups with and without severe sleep/wake pattern inefficiency, and reviews related literature.
