“…These studies have used bright white light (at least 2500 lux and as high as 8000 lux) for at least 1 hour in the morning, and treatment was carried on for at least 2 weeks. Results showed greater sleep efficiency at night, decreased sleep during daytime hours and, in some cases, reduced agitation behavior [39][40][41][42][43][44]. Unattended exposure to bright white light during the entire day improved rest/activity rhythms of people with AD.…”

This paper discusses a proposed 24-hr lighting scheme for older adults that can positively impact the aging visual, circadian and perceptual systems. New lighting was installed in eight private rooms in an assisted living facility. Measurements of residents' sleep quality and circadian rest-activity patterns were obtained, before and after the new lighting was installed. Consistent with predictions based upon previous research, the subjects who completed the study showed an improvement in sleep quality and rest/activity rhythms under the new 24-hr lighting scheme. In addition, all study participants reported a strong preference for the 24-hr lighting. The new lighting not only provides older adults with good lighting for performing their routine visual tasks, but also promotes high circadian light stimulation during the day and low circadian light stimulation at night. Although not studied here, but also discussed as part of the 24-hr lighting scheme, is the impact of a previously studied, novel night-light system that provides older adults with enhanced perceptual cues for nighttime navigation within the room. The new 24-hr lighting scheme appears to have important practical implications for improving the quality of life for seniors and will hopefully be adopted by architects, lighting specifiers and engineers.

“…Satlin et al (1992) found that evening exposure to light (1500-2000 lux, 7-9 pm) decreased nighttime activity and sundowning symptoms in 10 subjects with AD. Lyketsos et al (1999) administered morning light (10,000 lux) for 2 weeks to institutionalized patients with dementia and found that those patients who exhibited agitated behaviors slept more hours at night with the bright light exposure. Bright light did not, however, improve agitated behaviors in patients who did not exhibit disturbed sleep-wake cycles.…”

“…For example, dementia patients in chronic care, who were experiencing agitated behaviors, demonstrated improvement after undergoing bright light [12] [13]. Similarly, music therapy has been accepted as a safe and effective method for treating both agitation and anxiety in AD patients [14].…”

Timeslips™ is a group storytelling program that encourages creative expression among dementia patients without the pressure to recall the past. Analysis of the literature was conducted to determine the nine most relevant agitation and anxiety scales most appropriate for use with Timeslips in nursing home patients with dementia, who experience agitation and anxiety. Qualitative assessment of the nine scales was conducted to identify six criteria to determine the most pertinent characteristics for implementation of Timeslips within this patient population: 1) validity/reliability, 2) observation period, 3) training required, 4) time to administer, 5) most appropriate administrator and 6) accessibility/cost. Utilizing these six criteria, quantitative assessment was conducted using the Analytical Hierarchical Process (AHP) to identify that the Overt Agitation Severity Scale (OASS) was optimal. IRB approvals have been attained to investigate use of the OASS with Timeslips in the nursing home setting for patients with dementia, who experience agitation and anxiety.
