CONTEXT Cognitive decline, mood, behavioral and sleep disturbances, and limitations of activities of daily living commonly burden elderly patients with dementia and their caregivers. Circadian rhythm disturbances have been associated with these symptoms. OBJECTIVE To determine whether the progression of cognitive and noncognitive symptoms may be ameliorated by individual or combined long-term application of the 2 major synchronizers of the circadian timing system: bright light and melatonin…

The Effect of Bright Light Treatment on Rest–Activity Rhythms in People with Dementia: A 24-Week Cluster Randomized Controlled Trial
TLDR
The present results indicate that ambient bright light treatment did not improve rest–activity rhythms for people with dementia.
The effects of bright light treatment on affective symptoms in people with dementia: a 24-week cluster randomized controlled trial
TLDR
Compared to the control condition, affective symptoms were reduced after 16 weeks in the group receiving BLT, suggesting BLT may be beneficial for nursing home patients with dementia.
Long-Term, All-Day Exposure to Circadian-Effective Light Improves Sleep, Mood, and Behavior in Persons with Dementia
TLDR
A regular circadian-effective daytime lighting intervention can improve sleep at night and reduce depression and agitation in patients with dementia living in controlled environments.
Prevention of depression and sleep disturbances in elderly with memory-problems by activation of the biological clock with light - a randomized clinical trial
TLDR
If bright light therapy attenuates the worsening of sleep-wake rhythms and depressive symptoms, it will provide a measure that is easy to implement in the homes of elderly people with memory complaints, to complement treatments with cholinesterase inhibitors, sleep medication or anti-depressants or as a stand-alone treatment.

Effects of a Tailored Lighting Intervention on Sleep Quality, Rest-Activity, Mood, and Behavior in Older Adults With Alzheimer Disease and Related Dementias: A Randomized Clinical Trial.
TLDR
A lighting intervention tailored to maximally entrain the circadian system can improve sleep, mood, and behavior in patients with dementia living in controlled environments.
Light therapy and Alzheimer's disease and related dementia: past, present, and future.
TLDR
Research results from studies looking at the effectiveness of light therapy in improving sleep, depression, and agitation in older adults with ADRD, and future research needs are discussed.
Effects of bright light exposure on the behavioral and psychological symptoms of dementia and the burden on caregivers in institutionalized elderly with cognitive decline.
TLDR
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.
Progression of Dementia Assessed by Temporal Correlations of Physical Activity: Results From a 3.5-Year, Longitudinal Randomized Controlled Trial
TLDR
Results suggest a mechanistic link between multiscale activity regulation and circadian/sleep function in dementia patients and whether temporal activity patterns allow unobtrusive, long-term monitoring of dementia progression and mood changes is worth further investigation.
Bright light treatment in elderly patients with nonseasonal major depressive disorder: a randomized placebo-controlled trial.
TLDR
In elderly patients with MDD, BLT improved mood, enhanced sleep efficiency, and increased the upslope melatonin level gradient, and BLT produced continuing improvement in mood and an attenuation of cortisol hyperexcretion after discontinuation of treatment.

Morning bright light therapy for sleep and behavior disorders in elderly patients with dementia
TLDR
It is indicated that morning bright light is a powerful synchronizer that can normalize disturbed sleep and substantially reduce the frequency of behavior disorders in elderly people with dementia.
Double blind randomised placebo controlled trial of low dose melatonin for sleep disorders in dementia
TLDR
A randomised double blind placebo controlled cross over trial was undertaken to test the hypothesis that slow release exogenous melatonin 6 mg improves sleep for people with dementia.
Sleep/wake patterns In Alzheimer's disease: relationships with cognition and function
TLDR
The results indicate that with advancing severity of the disease, sleep/wake patterns are disrupted in parallel with the disturbances in cognition and function that are the hallmarks of AD, and suggest that the neural substrates underlying each process degenerate at somewhat comparable rates.
Circadian and sleep disturbances in the elderly
Circadian and sleep disturbances in the elderly.
TLDR
Age-related alterations in the circadian timing system appear to contribute strongly to these problems in healthy and demented elderly and may be reversible, since supplementation of stimuli that impinge on the SCN can re-activate these neurons and ameliorate disturbances in the sleep-wake rhythm.

Summary In order to investigate how the duration of actigraphic recordings affects the reliability of actigraphic estimates of sleep and 24-h activity rhythm variables, two to 3 weeks of
Improving actigraphic sleep estimates in insomnia and dementia: how many nights?
TLDR
It can be concluded that a valuable improvement in the reliability of actigraphic sleep estimates can be obtained by simply increasing the number of recording nights, and the results support the importance of day‐to‐day variability in insomnia and dementia, and even suggest the presence of ’week‐to-week’ variability.
The factor structure of the Cornell Scale for Depression in Dementia among probable Alzheimer's disease patients.
TLDR
The authors rated 137 outpatients with probable Alzheimer's disease on the Cornell Scale for Depression in Dementia as part of routine evaluation, showing moderate concordance with the five symptom clusters proposed in the original presentation of the CSDD.
