Radiation for Throat Cancer

Hi, everyone I have been on before my husband is getting radiation therapy for throat cancer. He does have his good days but it's the nights that are getting to me.He takes naps during the day. I.understand I try but can't always. Well when he has a really busy day or his really tired, it's like a person with sundowners, if you understand that. He gets confused.up and down all night. I got up and found him asleep sitting on the toilet. It gets worse. He is ok as long as I am beside him touching him but I am scared to fall asleep. They just put him on night feeding pump as well because of not getting enough during the day. Can the radiation bring on this kind of behavior? This is a worry cause is family has dementia in most of the older.women. Thanks for listening just really needed to vent
