dementia damages the brain. As a result, the person becomes unable to make sense of what he sees and hears. Not being able to make sense of things leads to confusion. This confusion may make the person frightened and anxious. This is why he sometimes insists on “going home,” why he lashes out in anger at you or resists care, why he believes that someone is stealing his money or trying to poison him. Most of these behaviors are not under his control, and he usually is trying as hard as he can. Other symptoms result more directly from the brain damage.
