Nighttime lighting to lower falls in people with Alzheimer's and related dementias

A Pragmatic Crossover Trial to Test the Effectiveness of a Novel Lighting System to Reduce Nighttime Falls in Persons with Alzheimer’s Disease and Related Dementias

NIH-funded research Univ of North Carolina Chapel Hill · NIH-11144500

This project uses a new nighttime lighting system to help people with Alzheimer's disease and related dementias get up at night with fewer falls.

What this research studies

You would remain in your assisted-living community while the study compares nights with a passive, balance-promoting lighting system versus usual lighting. Each participant experiences both lighting conditions in a randomized crossover design so researchers can compare fall rates within the same person. The lights are designed to turn on in a way that supports posture and walking without requiring you to change your behavior. The team builds on an earlier small trial that showed a 34% drop in falls and will track falls, injuries, and related healthcare use.

Who could benefit from this research

Good fit: Ideal candidates are ambulatory adults aged 65 or older with Alzheimer's disease or related dementias who live in assisted-living settings and sometimes get up at night.

Not a fit: People who are non-ambulatory, who do not wake at night, who live entirely at home with no assisted-living component, or who have very poor vision may not receive benefit.

Why it matters

Potential benefit: If successful, this could cut nighttime falls and reduce related injuries and hospital stays for people with dementia.

How similar studies have performed: A prior NIH R21 randomized crossover trial by the same team reported a 34% reduction in falls, indicating promising preliminary results.
