Help! Never sleeps, walks around like a drunk. I'm afraid if she don't get sleep she will drop and have a heart attack. Any advice?

Because of no sleep always want to be on the go. I know since she's been doing this my blood pressure has gone up to 241/199. I need some very good advice. Help!!!!! She is my mom 89 and lies alot, curses, talks to her self. Very combative. If can't have her way accuse you of holding her against her will and become very evil. She can look just like a demon. None of her personaility she use to have is not there any more. That sweet mom I use to know. These brain diseases is a demon (devil) diseases I would no wish this on anyone. 😭😰😢😥
