My Mother Is 90 Years Old And Has Dementia. We

My mother is 90 years old and has dementia. We have private caregivers that care for her in her home where she lives with my Dad....they are toileting her every 2 hours around the clock, I've been pondering this and feel this interrupts her sleep cycles and that this may affect her in negative ways. question: Does every 2 hour toileting at night adversely affect Mom ?
