My mother-in-law's sister has Dementia/Alheimer's. My mother-in-law calls her every Saturday at approximately 11:00 - 11:30 a.m. If her daughter isn't present when my Mother-in-law calls. The sister will tell her daughter that my Mother-in-law didn't call and says something may be wrong. It causes some chaos and makes my Mother-in-law uneasy. I would be open to suggestions. I believe that the sister needs calendar to mark/record that my Mother-in-law called her on Saturday, February 18 at such and such a time. She needs a clock that displays the time and displays the date. She is always asking what day it is which wears on her daughter. She has a companion working with her Monday -Friday. Maybe the companion could work this exercise into their daily schedule to stimulate her mind. Any thoughts or suggestions would help.
