What causes the patient to go through 24 to 48 hours of constant activity like he is working on his ranch?

i do remember working for an affluent local farmer with alz a few years ago. his near 90 yr old wife kept him out of most mischief but occasionally hed flee to the pastures and trod around with the cattle. the family must have had a heck of an understanding about life and death and the dangers associated with each.
his wife lived to 99. i know i spin out. evelyn was pretty sexy ( and industrious ) up till 99.

your SIL is a crackhead stegman but i could go along with the rest of what you said..

Does this happen with a full moon? I have a sister in law who cannot sleep during a full moon. Couple lunar influence with Alzheimer's and you have a perfect neurological storm. Rapidly falling barometric pressure, just before a storm, can also cause agitation in AD patients. This is not unnatural, and observations of wildlife will show many species more active in a full moon. Birds will load up at feeders when a storm approaches, dogs and cats will be hungry, then when the storm hits they hunker down, seek shelter and sleep. Why should humans be any different?
