@GreenWeaver - That’s true. I just wanted to say that the writer is absolutely correct with respect to the poor personal hygiene and the link with dementia.
My friend’s uncle had a disheveled appearance and did not bathe often. He was also suffering from dementia and was receiving anti-psychotic drugs because he was starting to become aggressive with the nursing staff at the assisted living facility that he was living in.
In fact because of his poor hygiene many of his children had limited contact with him because they were embarrassed by his body odor and appearance.
I really did not even think that the condition of dementia was related to his poor hygiene. Thank you for the information.
