Bright Light Therapy Reduces Depression and Agitation in Dementia Sufferers
Dementia is most often associated with memory loss, but seniors who suffer from the condition also experience depression and agitation. These symptoms are often treated with medication. But results of a new study, a collaboration between Radford University and Commonwealth Care of Roanoke (CCR), indicate bright light therapy reduces depression and agitation in dementia sufferers. The pioneering study was funded in part by an award from the Virginia Alzheimer’s and Related Diseases Research Award Fund and the Radford University Waldron Research Fund. Bright, full spectrum lighting confers the benefits of sunlight when sunlight is scarce, and Seasonal Affective Disorder (SAD) sufferers regularly use bright light therapy to combat depression, anxiety, insomnia, and other symptoms. Lora Epperly, a registered nurse, wondered if the same therapy could help her dementia patients. Epperly, who also serves as the Director of Business Development and Care Innovations with CCR, approached Lisa L. Onega, PhD, RN, a professor at the Radford University School of Nursing, about teaming up on the study. Onega conducted the eight-week study at four long-term care facilities managed by CCR. The results showed bright light therapy significantly reduced depression and agitation in the test group by more than half using standardized measurements. Families noticed the difference, and CCR is exploring ways to implement bright light treatment at their facilities.
