A team of Dutch scientists have found
that exposing dementia patients to nine hours of bright light each day
can significantly slow the progression of dementia.
It has often been suggested that some dementia behaviors and issues
are related to disruptions of the circadian rhythm within the body.
Circadian rhythm refers to the body's natural clock that is based on a
24 hour cycle.
The researchers at the Netherlands Institute for Neuroscience in
Amsterdam found that using 9 hours of bright light along with the sleep
hormone melatonin improved dementia subject's mood, sleep and behavior
issues by 5%.
