Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Be older than 18 years old

Timeline

Screening 3 weeks

Treatment Varies

Follow Up 24 hours everyday during the last 7 days of each condition, namely 7 days of baseline, 7 days of dynamic, and 7 days of placebo.

Summary

This trial uses special lighting to help older adults with dementia in long-term care facilities. The lighting mimics natural daylight patterns to improve their sleep and mood.

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.

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.

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.

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.
