I too have experienced a loved one with Sundowning... My Dad usually had this once a month. It wasn't that often, thank goodness, and he actually experienced it MORE in the beginning stages of his dementia than in the middle, or later.

He was diagnosed with Lewy-Body Dementia. Eventually we had to place him in the VA home with other patients of Alzheimers as we could not lift him, or give him the care he needed. Sometimes the ENTIRE set of residents would have it at the same time, once a month. Isn't that strange?

I found there was nothing I could do to prevent it, or fight it and that is was yet another thing to deal with as far as LBD was concerned. I visited every night after work, and I would stay as late as possible when Daddy was experiencing this because he was so restless and I knew the nurses and CNA's didn't have the time or manpower to give him one-on-one attention, which was what he needed and DESERVED. So I would stay until his meds for sleeping kicked in and he was resting peacefully.

A word of caution. Make sure your Mom is diagnosed properly before ANYBODY gives her meds of any kind. Some people I know had their loved ones diagnosed with dementia when in fact all they had was thyroid problems!
