My mum has advanced dementia, no speech, requires 24 hr care. She's in a care home. She was very ill a few weeks ago, drs said it was probably covid, but no swab test available. She recovered but since then has declined further - she's not been eating and is now not really drinking either. They're sending her to hospital for tests but gp said its more likely a hastening of the dementia. Is it likely this is nearing the end? I guess once she stops taking in fluids that's not a good sign.
