He wets the floor but not himself and talk to himself more frequently, sundowning appears
between 2 to 3 am
and he would be very active, yell out Hello, searching all sort of things
and hide them, making noises, hearing, seeing children with no legs and arm and hiding in panry, or objects and also relate himself to TV or radio and some time if he upsets then he can be nasty but just nudge gently, usually he is a gentle person.
