My Mom and Dad have been living with me for two years. My dad is still with me and constantly asks for "that woman" I ask if he means his wife Palmie and he says yes. I told him what happened and he cries. He did attend her wake and funeral but does not remember. He is constantly asking for her. He will something happened and again I will tell him and he cries as if it is the first time I tell him. I don't know what to day it is so upsetting for him and for myself. Any advise. I do believe he knows something is wrong but forgets what. His dementia has progressed a great deal since my mom passed in February. He is 94yrs old.
