Sundowning is not some sort of "new" discovery.

Geriatric psych. literature is rife with references to this phenomenon.

There are various strategies. Keep the blinds closed, discourage 
daytime napping to prevent insomnia, etc.

Light therapy would be an idea. Keep in mind that it likely must mimic 
sunlight and therefore be full-spectrum, and of an adequate LUX (units of 
light).

Perhaps it is an SCN (suprachiasmatic nucleus) deterioration thing.
