My mom is restless more and more. She walks around the house for hours. Mom has alzheimers. Lately she can't settle down. She walks around the house for hours. I can distract her briefly sometimes with a book or TV or a chore, but it only lasts for a few minutes. Right now it is 11 am and she's been walking around on and off for 4 hours. If today is like other days recently, she won't stop all day. Any ideas?
