My grandmother is 79 and she is suffering from Alzheimer's. The condition began to deteriorate few days earlier when she stopped taking food altogether. Other symptoms like a complete loss of coherence and occasional violent outbursts(especially if one is trying to feed her) are there. Her primary caregivers are her children. Though they are extremely sympathetic and patient with her, still the problem remains that the final amount of food she takes is just not enough to live on. She has been on a low dose of sedative and my uncle(who is a doctor) suggests to increase the dose. She has become physically very weak and even collapsed once the sedatives started. Is there any option other than sedating and artificially feeding her? And is there any possibility of slightest improvement from her present mental condition? Some of you might have gone through similar situations. Please help.
