What do you see?
Your relative may become odd, distant or just different from how they used to be. They may avoid contact with people and become less active. If they have delusional ideas, they may talk about them but may also keep quiet about them. If they are hearing voices, they may suddenly look away from you as if they are listening to something else. When you speak to them, they may say little, or be difficult to understand. Their sleep pattern may change so that they stay up all night and sleep during the day
