she's not physically fit to even use the bathroom. currently admitted in a hospital. she has not eaten or drank anything for more than 5 days. 
The symptoms that she has that I know of are that she keeps gazing in empty space, yelling at a health worker (told her to get out of the room), does not respond when asked whether she is aware that she is not physically and mentally fit (or to any other question), once had paranoia that we are on house arrest and that neighbours are spying on us (four months back, we took it for granted and now her disease has worsened).

The whole family is looking after her. she didn't even take medicine for chest infection she currently has. Now she's asking to get her home and that she doesn't want to switch hospitals. it's really hard to get her to do anything. 

is this common with schizophrenic patients? is there some way we can convince her to get diagnosed?
