Improve Measures of Sleep, Depression, and Agitation in Persons with Alzheimer’s Disease and Related Dementia.

“Light therapy has shown great promise as a nonpharmacological method to improve symptoms associated with Alzheimer’s disease and related dementias (ADRD), with preliminary studies demonstrating that appropriately timed light exposure can improve nighttime sleep efficiency, reduce nocturnal wandering, and alleviate evening agitation. Since the human circadian system is maximally sensitive to short-wavelength (blue) light, lower, more targeted lighting interventions for therapeutic purposes, can be used.”

Extend the Benefits of Therapy for those with PTSD.

“This research is exciting and unique because it points to an easy-to-use method for helping those with PTSD to retain the benefits of therapy long after the treatment ends,” said psychiatry professor William “Scott” Killgore, PhD, director of the Social, Cognitive and Affective Neuroscience (SCAN) Lab and senior author on the paper, “Morning blue light treatment improves sleep complaints, symptom severity, and retention of fear extinction memory in post-traumatic stress disorder.”
