My mother age of 92 yrs.she has lost her senses last ten or more days.she is not having food or anything. can u please suggest treatment?

Offer favorites: Sometimes, at advanced ages, the person just decides that their "time has come" and stops eating or drinking. Offer water in small amounts and small bites of favorite foods. Insure that there is no infection by checking temperature and possibly urinalysis. If temp normal and no urinary tract infection, continue to offer feedings and observe. She may begin to eat again spontaneously.
