Abstract:
Agitation and sleep disturbance are problematic for people with dementia and their carers, and have been linked to disrupted circadian rhythms caused by a lack of exposure to light. Bright light therapy (BLT) offers a powerful and cost-effective alternative to pharmacological options, and can be easily incorporated into care routines. This article describes practical issues faced when implementing light therapy in a nursing home setting, and attempts to address existing perceptions about its effectiveness.
