A few questions and answers.

Thank Marjorie for your question?

Individuals who have Dementia goes through these changes because it is
A mental disorder marked by memory failures, personality changes, and
impaired reasoning.

Never argue back with him instead always invite him to do something else
and while he is doing something else you remove his pack baggage and
because of memory failure, when he return he will forget that he was
leaving.

Thank Shirley for your question?
