How are circadian rhythms affected by dementia?

C. Boyer  asked the Naked Scientists:

Dear Dr. Chris,
 
I enjoyed your show on circadian rhythms!

I am curious about the following: a friend's husband at Harvard does research on circadian rhythm disturbances in Alzheimer's patients, and I wondered if circadian rhythm changes can now definitively be used to differentiate various forms of dementia?
 
Sincerely,
C. Boyer
Illinois, USA

What do you think?

The term "sundowning" refers to people who become increasingly confused at the end of the day and into the night.
Sundowning isn't a disease, but a symptom that often occurs in people with dementia, such as Alzheimer's disease.

Sundowning can also occur in vascular dementia, so it is not pathognomonic for Alzheimer's.
