Study Summary

This trial tests the effect of a special light intervention on sleep, circadian activity and moods of elderly people with dementia in long-term care.

Who is the study for?
This trial is for older adults over 50 with mild to major dementia who are not currently using light therapy or light-altering devices. They should have no major organ failure, significant additional diagnoses, history of head injury, obstructing cataracts, macular degeneration, or blindness.Check my eligibility
What is being tested?
The study tests dynamic lighting that changes intensity and spectrum throughout the day against placebo lighting in long-term care facilities. It aims to see if this can improve sleep quality, circadian rhythms, and mood in older adults with dementia.See study design
What are the potential side effects?
Since this trial involves lighting interventions rather than medication or invasive procedures, side effects may be minimal but could include discomfort due to changes in light exposure or potential disruption of usual sleep patterns.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Change in Nocturnal Sleep Duration (in minutes) as measured by actigraphy
Change in Percent Sleep Efficiency (total sleep time divided by time in bed) measured by actigraphy.
Changes in agitation levels measured by Cohen-Mansfield Agitation Inventory (CMAI).

2Treatment groups
Experimental Treatment
Group I: Placebo Condition followed by Dynamic ConditionExperimental Treatment2 Interventions
Each lighting condition will last for three weeks (Weeks 2-4 or 5-7). The order of conditions will be randomized. Sleep data will be collected only on the last 7 days of each condition using actigraphy. Light spectrum and intensity will be tracked continuously throughout the waking hours (wearable light tracker). Moreover, caregivers will complete two questionnaires (CSDD and CMAI) every seven days to assess the short and long-term effects of each condition on mood and agitation of older adult participants.
