Sleeping more, eating less. What does this mean?

More info from your profile: "I am caring for my mother Maria, who is 92 years old, living in my home with age-related decline, alzheimer's / dementia, anxiety, arthritis, broken hip, depression, hearing loss, incontinence, mobility problems, osteoporosis, and vision problems."

Well hopefully you have brought hospice on board by now, as sleeping more and eating less can be signs of end of life.
