Lighting intervention improves sleep and mood for Alzheimer's patients as daytime light exposure decreases sleep disturbances, depression and agitation, according to the American Academy of Sleep Medicine.

Alzheimer's disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

‘Daytime light exposure decreases sleep disturbances, depression and agitation, and enhances mood for Alzheimer's patients.’
Compared to baseline and to the inactive lighting condition, the lighting intervention significantly decreased sleep disturbances, depression and agitation. While all measures improved, the most significant improvement was seen in sleep quality. "Here we show that if the stimulus (light dose) is carefully delivered and measured, it can have a strong impact on sleep, depression and agitation," said principal investigator and lead author Mariana Figueiro, PhD, a professor and director at the Lighting Research Center at Rensselaer Polytechnic Institute in Troy, New York. "Depression was a secondary measure, and I was pleasantly surprised by the positive impact of the light treatment on depression scores."
The study involved 43 subjects diagnosed with Alzheimer's disease and related dementias who were exposed to an active and inactive tailored lighting intervention for successive 4-week periods, spaced by a 4-week washout period. The lighting intervention was added to spaces in which patients spent most of their waking hours and was energized from wake time until 6 p.m. Calibrated personal light meters monitored exposures. Measures of sleep disturbances (Pittsburgh Sleep Quality Index), mood (Cornell Scale for Depression in Dementia) and agitation (Cohen-Mansfield Agitation Index) were collected at baseline and during the last week of the intervention.
Genetics of Alzheimer’s disease
There are numerous genes that have been discovered that are associated with Alzheimer’s disease and indicate increased risk, aiding genetic counseling and better care.

Dementia - Types, Causes, Symptoms, Diagnosis, Treatment
Dementia has become a very big concern as we have an aging population across the world. Dementia is also terrifying to us because of its disturbing symptoms and limited treatment options.

Diet and Alzheimer's Disease
Alzheimer's begins with forgetfulness, but over time affects speech and coordination along with drastic behavioral changes. The right diet may lower your risk by 40%. So isn't a diet change worth it?
