Light treatment given during the day may improve sleep, depression and agitation in people with Alzheimer's disease and related dementia, according to a new study. The reason is that the light helps better regulate a person's circadian rhythm. The treatment tailered for four weeks led to a decrease in depression and agitation.
The discovery provides a non-pharmacologic, inexpensive way of dealing with symptoms associated with Alzheimer's and dementia.
A new study suggests that light treatment tailored to increase circadian stimulation during the day may improve sleep, depression and agitation in people with Alzheimer’s disease and related dementia. “The improvements we saw in agitation and depression were very impressive.” The study was published in the journal Sleep.
